For example, when the vehicle monitoring node monitors that a vehicle on the road has a fault, the control circuit board controls the first light emitting device 111 to emit a light signal for prohibiting passage (for example, the first light emitting device 111 emits red light); when the vehicle monitoring node monitors that the road is unobstructed, the control circuit board controls the first light-emitting device 111 to emit a light signal allowing the passage (for example, the first light-emitting device 111 emits green light); when the vehicle monitoring node monitors that the vehicle on the road runs slowly, the control circuit board controls the first light-emitting device 111 to emit a warning traffic light signal (for example, the first light-emitting device 111 emits yellow light).

In this embodiment of the application, the first light emitting device 111 may be formed by combining a plurality of LED beads, LED strips, or graphene lamps, and the expression form of the first light emitting device 111 may be the situation shown in fig. 1a, but certainly, the expression form of the first light emitting device 111 is not limited thereto, and the expression form of the first light emitting device 111 may be correspondingly adjusted according to actual needs and scenes, for example, the number of beads or the number of strips in the first light emitting device 111 may be reduced or increased, or the arrangement shape of the beads or the strips may be changed, and the like.

Optionally, the second protective cover 122 may be a protective cover made of a tempered glass material (such as a tempered ground glass material or a tempered non-ground glass material), or may be a protective cover made of other transparent or translucent materials with higher hardness. The second protective cover 122 may be made of the same or similar material as the first protective cover 112.

In the embodiment of the present application, the second light emitting device 121 can send out the optical signal for allowing the passage of light under the control of the control circuit board, and the second light emitting device 121 can also send out the optical signal for prohibiting the passage of light under the control of the control circuit board; alternatively, the second light emitting device 121 can emit an enable optical signal under the control of the control circuit board, the second light emitting device 121 can also emit an inhibit optical signal under the control of the control circuit board, and the second light emitting device 121 can also emit a warning enable optical signal under the control of the control circuit board.

For example, when there are two adjacent traffic lanes with opposite traveling directions, such as the traffic lane 1 and the traffic lane 2 adjacent to the traffic lane 1, and when a fault occurs on the traffic lane 1, and the traffic lane 2 is empty, the first light emitting device 111 of the road fault detection apparatus 10 on the traffic lane 2 may be controlled to emit a traffic prohibition light signal (e.g., the first light emitting device 121 emits red light) and the second light emitting device 121 emits a traffic permission light signal (e.g., the second light emitting device 121 emits green light), so that the vehicle on the traffic lane 1 travels through the traffic lane 2, and the traveling direction of the traffic lane 2 is changed to be opposite to the original traveling direction, that is, the traveling direction of the traffic lane 1 is the same as the traveling direction of the traffic lane 1; when the fault on the traffic lane 1 is resolved, the first light emitting device 111 of the road fault detection device 10 on the traffic lane 2 can be controlled to emit a light signal for allowing traffic (for example, the first light emitting device 121 emits green light) and the second light emitting device 121 emits a light signal for prohibiting traffic (for example, the second light emitting device 121 emits red light), that is, the vehicle on the traffic lane 1 is prohibited from passing through the traffic lane 2, and at this time, the traffic lane 2 returns to the original driving direction; when the indication signal of the second light emitting device 121 transits from the passage permission to the passage prohibition, the second light emitting device 121 of the road fault detection device 10 on the traffic lane 2 may also emit a warning light signal (for example, the second light emitting device 121 emits yellow light) to prompt the vehicle to be changed on the traffic lane 1. The road fault detection device 10 here performs the indicating function of a two-way traffic signal lamp.

In this embodiment of the application, the second light emitting device 121 may be formed by combining a plurality of LED lamp beads, LED lamp strips, or graphene lamps, and its expression form may be the same as or similar to that of the first light emitting device 111.

The road-type fault detection device 10 may be applied to an urban road, a suburban road, or an expressway. In practical applications, the road fault detection device 10 may be disposed in one or more entrance/exit lanes of a plane intersection (crossing) intersection, and is used to monitor traffic conditions in the entrance/exit lanes (e.g., whether a vehicle is in fault, whether a vehicle is slowing down, etc.), and to provide guidance for the traffic of vehicles behind.

Specifically, the distribution of the inlet/outlet channels of the planar intersection involved in the embodiment of the present application may be as shown in fig. 2a by way of example. In the example shown in fig. 2a, the plane intersection can be regarded as a plane intersection, and crosswalks are arranged between some entrance/exit lanes of the plane intersection and the intersection, and crosswalks are not arranged between other entrance/exit lanes and the intersection. In practical application, pedestrian crosswalks can be arranged between part or all of the inlet/outlet lanes of some plane intersections and intersections, and pedestrian crosswalks can not be arranged between part or all of the inlet/outlet lanes of some plane intersections and intersections. In fig. 2a, a cross-shaped planar intersection is taken as an example, however, the planar intersection may also be a T-shaped planar intersection or a planar intersection with another shape, and the embodiment of the present invention is not limited thereto.

Wherein all the inlet channels and outlet channels of the plane intersection are converged in the intersection area. The entrance lane of a level crossing may also be referred to as an entrance lane. An entry lane of a level crossing may include one or more entry lanes, which may also be referred to as entry lanes. The exit lane of the level crossing may also be referred to as a downstream lane. An exit lane of a level crossing may include one or more exit lanes, which may also be referred to as downstream lanes. In the drawings related to the embodiments of the present application, the inlet lane is mainly located on the right side of the corresponding outlet lane, and the inlet lane of some countries may also be located on the left side of the corresponding outlet lane, and so on. It is to be understood that the definition of the entrance lane and the exit lane is relative to the intersection, and the entrance lane of one level intersection may be the exit lane of the next level intersection, and the exit lane of one level intersection may be the entrance lane of the next level intersection. The road fault detection device 10 according to the embodiment of the present application may be disposed in one or several entrance/exit lanes, specifically, in the whole entrance/exit lane, or in a partial area of the entrance/exit lane (e.g., a frequent accident section).

In addition, another common distribution of planar intersection junctions involved in the embodiments of the present application can be exemplified as shown in fig. 2 b. In the example shown in fig. 2b, the planar intersection 300 includes 2 entrance lanes and 1 exit lane, and the 2 entrance lanes and the 1 exit lane converge in the intersection area, that is, the exits of the 2 entrance lanes are connected to the entrances of the intersection area, the entrances of the exit lanes are connected to the exits of the intersection area, and the traveling directions of the 2 entrance lanes are different. The plane intersection 400 includes 2 entrance lanes and 1 exit lane, and the 2 entrance lanes and the 1 exit lane converge in the intersection area, that is, the exit of the 2 entrance lanes is connected to the entrance of the intersection area, the entrance of the exit lane is connected to the exit of the intersection area, and the traveling directions of the 2 entrance lanes are the same. Because the intersection is often a high-speed road section of a traffic accident, the road-type fault detection device 10 can be arranged in 2 entrance lanes and/or 1 exit lane and/or an intersection area of the plane intersection 300 and the plane intersection 400, so that the accident on the road can be conveniently and automatically detected, and a vehicle behind the road can be indicated to reasonably avoid obstacles. It is understood that the plane intersection 300 and/or the plane intersection 400 may also be provided with more or less than 2 entrance lanes, and may also be provided with more than 1 exit lane, and the embodiment of the present invention is not limited thereto.

One possible way of arranging an array of road-based fault detection devices on the entrance/exit lanes may be as illustrated in fig. 4 for example. In fig. 4, the road includes an entrance lane 1, an entrance lane 2, an exit lane 1, and an exit lane 2, wherein each of the entrance lane 1, the entrance lane 2, the exit lane 1, and the exit lane 2 is provided with a road fault detection device, and a plurality of or all of the road fault detection devices on one entrance lane (or exit lane) may be regarded as a road fault detection device array, or a plurality of or all of the road fault detection devices on the entrance lane (or exit lane) may be combined to be regarded as a road fault detection device array. The main housing of any one of the road surface type fault detection devices may be partially buried under the road surface, or the main housing of any one of the road surface type fault detection devices may be attached to the road surface. When the road surface type fault detection device is installed, the first side surface of the road surface type fault detection device is perpendicular to the driving direction of the entrance lane (or the exit lane) where the road surface type fault detection device is located, and the direction of the first side surface is opposite to the driving direction of the vehicle, so that a driver can visually see an indicating light signal emitted from the first side surface in the driving process of the vehicle. Once each road surface type fault detection device is installed, the position of each road surface type fault detection device is fixed, and the position of an accident can be determined according to the road surface type fault detection device for detecting the accident. The front and back adjacent two pavement type fault detection devices in the pavement type fault detection device array can be in communication connection with each other, and the road type fault detection device array has the advantages that when one pavement type fault detection device detects that a vehicle has a fault, the front and back adjacent pavement type fault detection devices can be informed, the back pavement type fault detection device can also be informed of the back pavement type fault detection device, and therefore, the pavement type fault detection devices in a road section with the preset length can all send out traffic-prohibition optical signals (or traffic-warning optical signals) to prompt that an accident occurs in the front of the back vehicle, and obstacle avoidance preparation is well made.

Further, when a road fault detection device on the entrance lane 1 detects that a fault occurs, the road fault detection devices within a certain distance behind the road fault detection device are controlled to send out a light signal for forbidding passing from the first side surface, and at the moment, a vehicle behind the entrance lane 1 cannot pass on the entrance lane 1 continuously and can pass on the entrance lane 2 after changing the lane. In addition, when the exit lane 2 adjacent to the entrance lane 1 is vacant, the partial or entire road surface type failure detection device on the exit lane 2 may be controlled to emit the clear light signal from the second side surface and switch the clear light signal emitted from the first side surface to the no light signal, and at this time, the rear vehicle on the entrance lane 1 may enter the exit lane 2 and the exit lane 2 may be temporarily switched to the entrance lane. When the accident on the entrance lane 1 is removed, the road fault detection device on the entrance lane 1 can switch the light signal for forbidding passage from the first side surface to the light signal for allowing passage, the road fault detection device on the exit lane 2 can switch the light signal for allowing passage from the second side surface to the light signal for forbidding passage (or off), and the light signal for forbidding passage from the first side surface is switched to the light signal for allowing passage, at which time, the vehicles on the entrance lane 1 can not allow passage from the exit lane 2 any more. The bidirectional signal lamp is adopted for indicating, so that the passing efficiency of the vehicle can be improved, and traffic paralysis caused by accidents is avoided.

Wherein, the distance between any two adjacent road surface type fault detection devices 10 on any entrance lane (or exit lane) can be equal or partially equal or different. For example, the distance between any two adjacent road fault detection devices 10 on an entrance lane (or exit lane) may be 3 meters, 5 meters, 7.5 meters, 10 meters, 12 meters, or other values. As another example, in the traveling direction of the entrance lane (or the exit lane), the spacing between two adjacent road surface type failure detection devices 10 gradually decreases; alternatively, the distance between two adjacent road surface type failure detection devices 10 gradually increases in the traveling direction of the entrance lane (or the exit lane). Of course, the distance between two adjacent sensors on the entrance lane (or the exit lane) may also be varied randomly or in other variations, and does not necessarily exhibit the above-exemplified variations that gradually decrease or gradually increase in a certain direction.

Alternatively, the road fault detection device 10 may have at least one wireless and/or wired power input interface, and the at least one wireless and/or wired power input interface is coupled to the control circuit board and the vehicle monitoring node, respectively, and is connected to an external power supply circuit through the at least one wireless and/or wired power input interface to provide power for the control circuit board and the vehicle monitoring node. Specifically, the road fault detection device 10 may be connected to an external power supply circuit in a wireless manner and/or a wired manner, and obtain electric energy from the external power supply circuit to maintain electric energy required by normal operation of each functional module, where the external power supply circuit may be a power grid, a power station, a power box, a storage battery, or the like.

Optionally, the road surface type fault detection device 10 may also have a power supply circuit, for example, a power supply block (such as a storage battery or other battery with strong cruising ability) is arranged in the road surface type fault detection device 10, and the power supply block can supply power to each functional module in the road surface type fault detection device 10.

Alternatively, the road fault detection device 10 may also adopt a new energy power supply module, such as a common solar power supply module. Specifically, please refer to fig. 4a and 4b together, in which fig. 4a is a schematic top view of another road fault detection apparatus provided in the embodiment of the present application; fig. 4b is a schematic top view of a main housing of the pavement fault detection apparatus illustrated in fig. 4a according to an embodiment of the present disclosure. The road fault detection device 10 shown in fig. 4a and 4b may further include a solar cell panel 131 and a third protection cover 132 besides the structure described in fig. 1a and 1b, a third receiving cavity 133 for receiving the solar cell panel 131 is disposed on the top surface of the main housing 110, the third protection cover 132 covers an opening surface of the third receiving cavity 133 for receiving the solar cell panel 131, a sealing and waterproof structure is formed between the opening surface of the third receiving cavity 133 and the third protection cover 132, and an optical signal in an external environment can partially or completely penetrate through the third protection cover 132; the solar cell panel 131 is connected to the control circuit board and the vehicle monitoring node, respectively, and is configured to provide electric energy to the control circuit board and the vehicle monitoring node.

The solar cell panel 131 may be composed of a plurality of cells, such as 4, 6, 8, and so on. The third protecting cover 132 may be a protecting cover made of a tempered glass material with high hardness and good light transmittance (generally, light transmittance is more than 91%), and preferably, the third protecting cover 132 is a protecting cover made of a super white tempered glass material. The road fault detection device 10 converts solar energy in the external environment into electric energy through the solar cell panel 131, and supplies power to each functional module in the road fault detection device 10, so as to maintain normal operation of the road fault detection device 10. In addition, adopt solar cell panel to supply power and traditional adoption built-in battery to supply power and compare, the benefit lies in can directly utilizing environmental resource, and inexhaustible, and can solve road surface formula fault detection device because of the limited problem that needs often to change the battery of battery electric power storage.

It is to be understood that the above embodiments are illustrative of the shape, size, etc. of the road surface type fault detection device, and in practical applications, the shape, size, etc. of the road surface type fault detection device may be adjusted schematically.

As can be seen from the above, the road fault detection apparatus in some embodiments of the present application includes a main housing, a control circuit board, a vehicle monitoring node, a first light emitting device, a second light emitting device, a first protective cover, and a second protective cover, where the control circuit board is connected to the vehicle monitoring node, the vehicle monitoring node is configured to sense a passing vehicle and obtain running state information of the passing vehicle, so as to determine whether a vehicle has a fault, the first light emitting device and the second light emitting device are disposed on two opposite sides of the main housing, and the first light emitting device and the second light emitting device are respectively connected to the control circuit board and respectively controlled by the control circuit board, and the first light emitting device and the second light emitting device can be controlled to emit different indication light signals when a road is in different traffic states, for example, when the vehicle monitoring node located on a certain lane monitors that a vehicle has a fault or slowly travels, the control circuit board can control the first light-emitting device to emit a traffic prohibition or traffic warning light signal to prompt a rear vehicle to prohibit the rear vehicle from advancing on the traffic lane, so that the rear vehicle can change lanes in advance to avoid a front fault; when the vehicle monitoring node monitors that the traffic lane is unobstructed, the control circuit board can control the first light-emitting device to emit a light signal allowing traffic, and then a rear vehicle can normally move forward on the traffic lane. When a certain lane has a fault, the vehicle on the failed lane can be switched to the adjacent lane by adjusting the second light-emitting device of the road fault detection device on the adjacent lane. The traffic state on the road is automatically monitored through the vehicle monitoring node, and the indicating light signals sent by the first light-emitting device and the second light-emitting device indicate the passing of the rear vehicle, so that a certain hardware foundation can be laid for timely obstacle avoidance when the vehicle runs on the road, and particularly, the pavement type fault detection device is applied to a road section with multiple accidents, and the passing efficiency and the safety performance of the traffic can be improved.

In addition, in some embodiments of the present application, the pavement-type fault detection device may further include a solar cell panel disposed on the top surface of the main housing, and solar energy is converted into electric energy through the solar cell panel to supply power to each functional module in the pavement-type fault detection device, so that the pavement-type fault detection device can work normally, and the problem that the pavement-type fault detection device needs to replace the battery frequently due to limited battery storage is also solved.

The embodiment of the application also provides a fault emergency processing system of the adjacent traffic lanes.

Referring to fig. 5, the emergency fault handling system for adjacent traffic lanes may include:

the signal controller 200 is connected to the road surface type fault detection device array 100, and is configured to receive feedback information sent by each road surface type fault detection device 10, and analyze each feedback information to determine whether there is a fault in each feedback information; if the fault feedback information exists, determining a traffic lane xi where the road surface type fault detection device sending the fault feedback information is located, controlling a first light-emitting device of the road surface type fault detection device sending the fault feedback information to emit a traffic prohibition light signal or a traffic warning light signal, and controlling a first light-emitting device of the road surface type fault detection device within a preset distance behind the road surface type fault detection device sending the fault feedback information to emit the same light signal as the road surface type fault detection device sending the fault feedback information along the running direction of the traffic lane xi;

the signal controller 200 is further configured to control a first light emitting device of the road surface type failure detection apparatus, which is a part or all of the traffic lane yi, to emit a light signal for prohibiting passage of traffic, and control a second light emitting device of the road surface type failure detection apparatus, which is a part or all of the traffic lane yi, to emit a light signal for permitting passage of traffic, when it is determined that no vehicle passes through the traffic lane yi, which is adjacent to the traffic lane xi and has an opposite traveling direction.

In the embodiment of the present application, the road surface type fault detection device i may have at least one wireless and/or wired control signal input interface, so that the road surface type fault detection device i may establish a communication connection with the control signal output interface of the signal controller 200 in a wireless and/or wired manner. In addition, the road fault detection device i may further have at least one wireless and/or wired control signal output interface, and the control signal output interface is connected to the signal controller 200 and the control circuit board, respectively, so that the road fault detection device i may establish a communication connection with the control signal input interface of the signal controller 200 in a wireless and/or wired manner. Based on the above communication process, communication interaction between the road-based fault detection device i and the signal controller 200 can be realized.

Specifically, the main housing 110 of the pavement type fault detection device i may be partially buried under the pavement of the traffic lane, for example, the traffic lane is provided with a plurality of grooves, and the main housing 110 of the pavement type fault detection device i is partially embedded in the grooves; alternatively, the main housing 110 of the road-type failure detection device i may be attached to the road surface of the traffic lane. The array 100 of road-based fault detection devices is disposed on the ground of two adjacent traffic lanes with opposite driving directions, which may be two or any two adjacent traffic lanes with opposite driving directions, and particularly, may be one of an entrance lane and an adjacent exit lane at a plane intersection of a road, or one of the entrance lane and the adjacent exit lane at a plane intersection of a road. That is, part or all of the adjacent entrance lanes and exit lanes of the plane intersection may be deployed with the road fault detection device in a deployment manner identical or similar to the above-described traffic lanes.

The roads referred to in the embodiments of the present application may be urban roads (including overpasses, viaducts), suburban roads, expressways, or the like. In practical applications, the road surface type fault detection device may be disposed on part or all of the traffic lanes of the roads such as urban roads, suburban roads, and expressways, and the manner of disposing the road surface type fault detection device on part or all of the traffic lanes may be the same or similar.

Whether a vehicle passes through can be sensed through the vehicle monitoring node, and the running state information of the passing vehicle, such as the running speed, the running position, the running duration, the running direction and the like of the passing vehicle, is obtained.

Alternatively, the vehicle monitoring node may be separately disposed outside of main housing 110, or the vehicle monitoring node may be packaged inside main housing 110, or the vehicle monitoring node may be disposed on a surface of main housing 110 (e.g., on either side or a top surface of main housing 110).

After the signal controller 200 establishes communication connection with each road surface type fault detection device 10 in the road surface type fault detection device array 100, it can receive feedback information sent by each road surface type fault detection device 10. Each road fault detection device 10 may send feedback information to the signal controller 200 every fixed time period (e.g., 5 seconds, 10 seconds, 30 seconds, etc.), or send feedback information to the signal controller 200 when it senses that a vehicle passes through, where the feedback information sent by the road fault detection device 10 may include the obtained driving state information of the passing vehicle, and may include, but is not limited to, a real-time position of the vehicle (i.e., a position where the current road fault detection device 10 is located), a driving speed of the vehicle (i.e., a speed value passing through the road fault detection device 10), a driving time period (i.e., a time required to pass through the road fault detection device 10), a driving direction of the vehicle, identity information of the vehicle (e.g., an electronic license plate of the vehicle, a vehicle identification number VIN), and the like.

In the embodiment of the present application, each of the road surface type fault detection devices in the road surface type fault detection device array 100 may operate under the driving control of the signal controller 200. The signal controller 200 may analyze the received feedback information to determine whether there is a fault in the feedback information, specifically, the signal controller 200 matches the received feedback information with preset model data, and if the driving speed included in the feedback information is lower than a preset speed, or the driving duration included in the feedback information exceeds a preset duration, it may be determined that the sensed vehicle has a fault such as stopping or slow driving, and accordingly, it may be determined that there is a fault in the feedback information at this time. If the signal controller 200 analyzes that the feedback information sent by a certain road fault detection device has fault feedback information, it can determine the traffic lane xi where the road fault detection device is located, and then control the first light emitting device of the road fault detection device to send out a light signal for prohibiting traffic or a light signal for warning traffic, and control the first light emitting device of the road fault detection device within a preset distance behind the road fault detection device to send out the same light signal as the road fault detection device along the driving direction of the traffic lane xi. At the moment, the second light-emitting device of the road surface type fault detection device and the second light-emitting device of the road surface type fault detection device within the preset distance behind the second light-emitting device send out a traffic-prohibition light signal by default or are turned off. Further, the signal controller 200 may monitor whether a traffic lane yi adjacent to the traffic lane xi and having an opposite driving direction is empty, and if empty (i.e., no vehicle passes through the traffic lane yi), may control a first light emitting device of a road surface type failure detecting apparatus of a portion (e.g., a portion adjacent to a length of a lane section on the traffic lane xi where a failure occurs and the lane section is prohibited) or all of the road surface type failure detecting apparatus to emit a light signal for prohibiting passage of traffic, and control a second light emitting device of the above-mentioned portion or all of the road surface type failure detecting apparatus to emit a light signal for permitting passage of traffic. At this time, the road surface type failure detection device in part or all of the traffic lane yi changes the traveling direction of the traffic lane yi, that is, the traveling direction originally opposite to the traffic lane xi, to the same traveling direction, so that the vehicle traveling on the upper rear side of the traffic lane xi can pass through the traffic lane yi. The road type fault detection device in a certain distance of the accident road section is controlled to send out the indicating light signal, so that a driver of a vehicle at the rear can visually know the traffic road condition in front, and can timely make corresponding measures such as deceleration and the like according to the road condition, and then the vehicle on the fault lane is allowed to pass by changing the running direction of the adjacent traffic lane, so that the vehicle on the fault lane can be driven by changing the lane to avoid the obstacle, the congestion caused by the fault is relieved, the traffic running efficiency is improved, and certain assistance is provided for relieving the fault.

The traffic lane xi is one of two adjacent traffic lanes in which the road fault detection device included in the road fault detection device array 100 is located and the traveling directions of which are opposite, and the traffic lane yi is the other of the two traffic lanes. The signal controller 200 may store the identification number and the position information of each road surface type fault detection device in advance, the identification number of the road surface type fault detection device may be used to uniquely identify the identity of the road surface type fault detection device, and the identification numbers of different road surface type fault detection devices are different. The position information of the road surface type fault detection device may include, but is not limited to, at least one of a traffic lane where the road surface type fault detection device is located, a specific position on the traffic lane, longitude and latitude, and the like. The road fault detection device also sends the self identity identification number by default while sending the feedback information to the signal controller 200, so that the signal controller 200 confirms the identity of the road fault detection device through the identity identification number, and then the position information of the road fault detection device corresponding to the identity identification number can be acquired from a plurality of pieces of position information stored in advance, and the lane where the road fault detection device is located is determined. Whether the first light emitting device of the road surface type fault detection device which detects the fault emits the light signal for prohibiting passing or the light signal for warning passing can be determined according to which preset speed interval in the preset model data the running speed included in the feedback information acquired by the road surface type fault detection device is located or which preset time interval in the preset model data the running time included in the acquired feedback information is located. For example, the smaller the speed value included in the preset speed interval, the preset speed interval may correspond to the optical signal that is prohibited from being passed through; the greater the speed value contained in the preset speed interval is, the preset speed interval can correspond to the warning traffic light signal. Different preset duration intervals correspond to different indication optical signals, for example, if a duration value included in the preset duration interval is larger, the preset duration interval may correspond to the optical signal prohibited from being communicated; the smaller the time length value contained in the preset time length interval is, the smaller the preset time length interval can correspond to the warning traffic light signal.

In addition, the preset distance may be a predetermined fixed distance, such as 50 meters, 75 meters, 100 meters, 150 meters, 200 meters, or other values. The preset distance may also be determined according to which preset speed interval in the preset model data the driving speed included in the acquired feedback information is located or which preset duration interval in the preset model data the driving duration included in the acquired feedback information is located. The preset distances corresponding to different preset speed intervals may be different, for example, the smaller the speed value included in the preset speed interval is, the larger the corresponding preset distance may be, the larger the speed value included in the preset speed interval is, the smaller the corresponding preset distance may be. The preset distances corresponding to different preset time length intervals may be different, for example, the larger the time length value included in the preset time length interval is, the larger the corresponding preset distance may be, and the smaller the time length value included in the preset time length interval is, the smaller the corresponding preset distance may be. The determination of whether or not a vehicle passes through the traffic lane yi by the signal controller 200 may be determined according to whether or not the signal controller 200 receives the feedback information sent by the road surface type failure detection device in the traffic lane yi within a certain period of time, or whether or not the received feedback information includes vehicle information. For example, if the feedback information transmitted from any one of the road surface type failure detection devices in the traffic lane yi is not received for a while, it can be considered that no vehicle passes through the current traffic lane yi. For another example, the feedback information sent by each road fault detection device in the traffic lane yi is received, which does not include vehicle information, that is, all vehicles are sensed, and at this time, it can be considered that no vehicle passes through the current traffic lane yi. It is understood that, when the fault on the traffic lane xi is resolved, the signal controller 200 may control the first light emitting device of the above-mentioned partial or all road surface type fault detection apparatus in the traffic lane yi to be switched from the no-passing light signal to the no-passing light signal, and the second light emitting device to be switched from the no-passing light signal to the no-passing light signal or to be turned off, so as to prevent the vehicle on the traffic lane xi from entering the traffic lane yi, and at this time, the driving direction of the traffic lane yi will be restored to the original driving direction, that is, the driving direction opposite to the traffic lane xi.

Optionally, the signal controller 200 may control the road surface type fault detection device in the traffic lane yi to switch the indication light signal to change the driving direction of the traffic lane yi when it is determined that the fault on the traffic lane xi is serious (for example, the fault causes the first light emitting device corresponding to the road surface type fault detection device to emit the no-pass light signal) and no vehicle passes through the traffic lane yi, and may not change the driving direction of the traffic lane yi when the fault on the traffic lane xi is light (for example, the fault causes the first light emitting device corresponding to the road surface type fault detection device to emit the warning pass light signal).

Optionally, the fourth accommodating cavity is disposed on the bottom surface of the main housing 110, and the pavement fault detection device i may further include a bottom plate, wherein the bottom plate covers an opening surface of the fourth accommodating cavity that accommodates the control circuit board, and a sealing and waterproof structure is formed between the opening surface of the fourth accommodating cavity and the bottom plate. Optionally, a waterproof wire routing hole for external routing may be further disposed on the bottom plate. Optionally, a fourth accommodating cavity accommodating the main control circuit board is filled with waterproof sealing cement.

Optionally, the road-type fault detection device i may further include a solar cell panel 131 and a third protective cover 132, a third receiving cavity 133 for receiving the solar cell panel 131 is disposed on the top surface of the main housing 110, the third protective cover 132 covers an opening surface of the third receiving cavity 133 for receiving the solar cell panel 131, a sealed and waterproof structure is formed between the opening surface of the third receiving cavity 133 and the third protective cover 132, and an optical signal in an external environment can partially or completely penetrate through the third protective cover 132; the solar cell panel 131 is connected to the control circuit board and the vehicle monitoring node, respectively, and is configured to provide electric energy to the control circuit board and the vehicle monitoring node.

Optionally, the road surface type fault detection device i may have at least one wireless and/or wired power input interface, where the at least one wireless and/or wired power input interface is coupled with the control circuit board and the vehicle monitoring node, respectively, and is connected with an external power supply circuit through the at least one wireless and/or wired power input interface to provide electric energy for the control circuit board and the vehicle monitoring node.

Optionally, the signal controller 200 may be further configured to control a first light emitting device of each road surface type fault detection apparatus in the road surface type fault detection apparatus array 100 to emit an optical signal for allowing light to pass through and control a second light emitting device of each road surface type fault detection apparatus in the road surface type fault detection apparatus array 100 to emit an optical signal for prohibiting light to pass through when it is determined that no fault feedback information exists in each feedback information.

Specifically, when no fault occurs on the traffic lane, the first light-emitting devices of the road fault detection devices on the traffic lane can be controlled to emit a light signal allowing traffic and the second light-emitting devices can be controlled to emit a light signal prohibiting traffic or be turned off; alternatively, when the trouble occurring on the traffic lane is resolved, the first light emitting device of the road-type trouble detecting apparatus on the traffic lane may be controlled to switch from emitting the no-traffic light signal or the warning-traffic light signal to emitting the permission-traffic light signal.

In practical applications, the distances between any two adjacent road fault detection devices on each traffic lane may be equal or partially equal or different from each other. Specifically, the distance between any two adjacent road-type fault detection devices belonging to the same lane can be completely equal; or, along the driving direction of a traffic lane, the distance between two adjacent road-type fault detection devices on the traffic lane is gradually reduced; alternatively, the distance between two adjacent road-type failure detection devices on a traffic lane gradually increases in the traveling direction of the traffic lane.

The signal controller 200 mentioned in the embodiment of the present application may also be referred to as a signal, a program controlled switch, a traffic control signal, a traffic signal, an intersection traffic signal, or an intersection traffic control signal, and the like. Specifically, the signal controller 200 transmits a control signal to the control signal input interface of the road fault detection apparatus through the control signal output interface, and drives and controls the first light emitting device and/or the second light emitting device to operate through the control circuit board of the road fault detection apparatus.

It can be seen that the fault emergency processing system provided by some embodiments of the present application senses passing vehicles by using an array of road fault detection devices disposed on the ground of two adjacent traffic lanes of a road and having opposite driving directions, and obtains the running state information of the passing vehicle, and analyzes the obtained running state information through the signal controller to determine whether the sensed vehicle has a fault (such as vehicle stop or slow running), if a fault occurs, determining a lane where the fault is located, controlling a first light-emitting device of the road surface type fault detection device which senses the fault to emit a light signal for prohibiting passing or a light signal for warning passing, controlling a first light-emitting device of the road surface type fault detection device within a preset distance behind the road surface type fault detection device sensing the fault to emit the same optical signal as the road surface type fault detection device sensing the fault along the running direction of a traffic lane where the fault is located; further, when it is determined that no vehicle passes through a traffic lane adjacent to the failed traffic lane and having an opposite traveling direction, it is possible to control a part or all of the first light emitting devices of the road surface type failure detecting means in the adjacent traffic lane to emit a light signal for prohibiting passage of traffic, and to control a part or all of the second light emitting devices of the road surface type failure detecting means to emit a light signal for permitting passage of traffic. Therefore, traffic faults on urban roads or expressways can be intelligently monitored in real time, corresponding indication light signals are sent out by controlling the road fault detection device, and vehicles behind can be timely notified, so that the vehicles behind can be decelerated in advance or the vehicles behind can be switched to go out to avoid obstacles; in addition, when the adjacent traffic lane is idle, the driving direction of the adjacent traffic lane can be changed by controlling the road fault detection device on the adjacent traffic lane, so that the vehicle on the traffic lane with the fault passes through the adjacent traffic lane, and the passing efficiency of the vehicle can be improved. In addition, the system is applied to the road sections with multiple accidents, and the traffic efficiency and the safety performance can be improved.

Referring to fig. 6, the road with the fault detection function may include a roadbed (not shown in the figure) and a road surface disposed on the roadbed, wherein at least two traffic lanes are disposed on the road surface, and driving directions of two adjacent traffic lanes in the at least two traffic lanes are opposite, a traffic lane xi and a traffic lane yi are disposed as shown in the figure, and both the traffic lane xi and the traffic lane yi are provided with grooves, and any one of the road fault detection devices 10 described in the above embodiments is embedded in the groove.

The road mainly comprises a roadbed and a pavement, and the road can be an urban road, a suburban road, an expressway and the like. The roadbed may be regarded as the foundation of a road, which is located below the road surface, and the road surface is laid above the roadbed for vehicles to travel.

Specifically, a plurality of grooves are formed in the traffic lane xi and the traffic lane yi, and a road type fault detection device 10 is embedded in each groove, so that a road type fault detection device array 100 is formed, and is used for monitoring the running state information of vehicles passing through the traffic lane to determine whether an accident occurs, and when the accident is monitored, the rear vehicle is prompted by sending an indication light signal, so that the rear vehicle is ready for obstacle avoidance in time. Wherein the shape and size of the groove are adapted to the shape and size of the main housing 110 of the pavement-type fault detection device 10. Optionally, when the vehicle monitoring node is independently disposed outside the main housing 110 of the road fault detection device 10, a groove may be further formed beside each groove for embedding the vehicle monitoring node for monitoring the driving state information of the passing vehicle. The shape and the size of the groove for deploying the vehicle monitoring node are matched with those of the vehicle monitoring node. And a strip-shaped groove for wiring can be formed between two adjacent grooves, so that the control circuit board of the road fault detection device 10 and the vehicle monitoring node are in wiring communication connection. The signal controller 200 may be disposed on the roadside of the traffic lane, and the signal controller 200 establishes a wired and/or wireless connection with each of the road fault detection devices 10 disposed on the traffic lane xi and the traffic lane yi, respectively, so as to realize communication interaction between the signal controller 200 and any one of the road fault detection devices 10. When a vehicle on the traffic lane xi has a fault sensed by the road fault detection device, the signal controller 200 may control the road fault detection devices on the traffic lane xi within a preset distance or a preset number from the road fault detection device to send out a traffic prohibition light signal or a traffic warning light signal. In addition, when no vehicle passes through the traffic lane yi, the signal controller 200 may further control some or all of the road surface type fault detection devices on the traffic lane yi to send out an indication light signal to change the traveling direction (i.e., the vehicle passing direction) of the traffic lane yi, so that the vehicle on the traffic lane xi passes through the traffic lane yi, and thus, the traffic jam and other conditions caused by the fault are alleviated.

The specific functions and structures of the road fault detection device 10 may refer to all or part of the contents described in the foregoing embodiments, and the specific functions of the signal controller 200 may also refer to all or part of the contents described in the foregoing embodiments, which will not be described again here.

It can be understood that, when the pavement-type fault detection device 10 is disposed on a road in a mounting manner, the pavement-type fault detection device 10 can be directly mounted on the surface of the traffic lane without forming a groove on the traffic lane.

Some embodiments of the present application provide a road with a fault detection function, wherein two adjacent traffic lanes with opposite driving directions are disposed on the road, a plurality of grooves are arranged on each lane, a road type fault detection device is embedded in each groove, the road surface type fault detection device can automatically monitor the traffic state on the current traffic lane, judge whether the road conditions such as fault or slow traffic exist or not through the signal controller, when a fault occurs on one traffic lane, the road fault detection device on the traffic lane can be controlled to send out an indication light signal to inform a rear vehicle, and when the other traffic lane is idle, the driving direction of the other traffic lane is changed by controlling the road-type fault detection device on the other traffic lane to switch the indication light signal, the vehicle on the accident traffic lane can be allowed to pass on another traffic lane, so that the passing efficiency and the safety performance of traffic are improved.

The embodiment of the application also provides a fault emergency treatment method for the adjacent traffic lanes. The adjacent traffic lane fault emergency processing method can be applied to the adjacent traffic lane fault emergency processing system disclosed in the above embodiment. Referring to fig. 7, the method for emergency handling of a fault of an adjacent traffic lane may include the following steps:

710. the fault emergency processing system senses a passing vehicle on a traffic lane of a road by using the road surface type fault detection device array 100 and acquires running state information of the passing vehicle.

One or any one of the road fault detection devices in the array 100 of road fault detection devices includes a first light emitting device disposed on a first side surface of the housing and a second light emitting device disposed on a second side surface of the housing, where the first side surface and the second side surface are two opposite side surfaces on the housing. When the road type fault detection device is arranged on the ground, the first side face faces the direction of the passing vehicle on the traffic lane, namely, the driver can visually see the first side face of the road type fault detection device. The road surface type failure detection device array 100 is disposed on the ground of two adjacent traffic lanes of a road, which are opposite in traveling direction. Specifically, the housing of one or any one of the road surface type fault detection devices in the road surface type fault detection device array 100 may be partially buried under the road surface of the traffic lane, or the housing of one or any one of the road surface type fault detection devices in the road surface type fault detection device array 100 may be attached to the road surface of the traffic lane. One or any one of the above-mentioned at least one road surface type fault detection devices may be the road surface type fault detection device 10 in the foregoing embodiment, and the specific structure and function thereof may refer to part or all of the contents of the road surface type fault detection device 10 in the foregoing embodiment. The vehicle monitoring node integrated in the road fault detection device can be used for sensing a passing vehicle on a lane where the passing vehicle is located and acquiring running state information of the passing vehicle, wherein the vehicle monitoring node can include but is not limited to at least one of a geomagnetic sensor, a piezoelectric sensor (such as a gravity sensor), a photoelectric sensor (such as a laser sensor, an infrared sensor and the like), an ultrasonic sensor, a capacitive sensor and the like. The driving state information of the vehicle may include, but is not limited to, a driving speed, a driving time period, a driving direction, a driving location, identity information of the vehicle, and the like when the vehicle passes through the road fault detection device.

720. The fault emergency processing system determines whether the vehicle sensed by the road surface type fault detection device of the vehicle has a fault according to the running state information acquired by the road surface type fault detection device of the vehicle sensed in the road surface type fault detection device array 100, determines a traffic lane xi where the road surface type fault detection device of the vehicle is sensed if the vehicle has the fault, controls a first light-emitting device of the road surface type fault detection device of the vehicle sensed to emit a traffic prohibition light signal or a traffic warning light signal, and controls a first light-emitting device of the road surface type fault detection device within a preset distance behind the road surface type fault detection device of the vehicle sensed to emit the same light signal as the road surface type fault detection device of the vehicle sensed along the running direction of the traffic lane xi.

Each road surface type fault detection device is provided with an identity identification number for uniquely identifying the identity of the road surface type fault detection device. The position information and the identification number of each road surface type fault detection device in the road surface type fault detection device array 100 can be stored in advance, and the position of the road surface type fault detection device is determined by sensing the identification number of the road surface type fault detection device of the vehicle, so that the lane to which the fault belongs can be known. The traffic lane xi and the traffic lane yi are those two adjacent traffic lanes in which the road surface type failure detection devices in the road surface type failure detection device array 100 are disposed and in which the traveling directions are opposite. It should be noted that the second light emitting device of the road surface type fault detection device sensing the vehicle and the road surface type fault detection device within the preset distance behind sends out the traffic prohibition light signal or extinguishes by default. The first light emitting device of the road surface type fault detection device on the road section where no accident occurs in front of the road surface type fault detection device for sensing the vehicle emits the light signal for allowing the traffic light and the second light emitting device emits the light signal for forbidding the traffic light or extinguishes.

730. When the fault emergency processing system determines that no vehicle passes through a traffic lane yi which is adjacent to the traffic lane xi and has the opposite driving direction, the fault emergency processing system controls a first light-emitting device of a part or all of the road surface type fault detection devices in the traffic lane yi to emit a light signal for forbidding passing, and controls a second light-emitting device of the part or all of the road surface type fault detection devices to emit a light signal for allowing passing.

Optionally, the step 720 may include the following steps, according to the driving state information acquired by the road fault detection device sensing the vehicle in the road fault detection device array 100, in a specific implementation manner, the fault emergency processing system determining whether the vehicle sensed by the road fault detection device sensing the vehicle has a fault:

71) the fault emergency processing system determines whether the driving speed included in the acquired driving state information is lower than a preset speed according to the driving state information acquired by the road type fault detection device sensing the vehicle in the road type fault detection device array 100, and if the driving speed included in the acquired driving state information is lower than the preset speed, determines that the vehicle sensed by the road type fault detection device sensing the vehicle has a fault.

Specifically, preset model data may be stored in advance, where the preset model data may include a preset speed, and when the road fault detection device senses that a vehicle passes through the road fault detection device and obtains a running speed of the vehicle, the running speed may be matched with the preset speed in the preset model data, and if the running speed of the vehicle is greater than or equal to the preset speed, the vehicle may be considered to be in a normal running state; if the running speed of the vehicle is less than the preset speed, the vehicle can be considered to be in an abnormal running state, such as slow running or stop running, and at this time, the vehicle can be considered to be in a fault. In addition, the preset model data may include more than one preset speed, and the severity level of the fault may be determined according to a speed interval in which the driving speed of the vehicle falls, where the lower the speed is, the higher the severity level of the fault is, and conversely, the lower the severity level of the fault is.

72) the fault emergency processing system judges whether the driving time included in the acquired driving state information is longer than a preset time according to the driving state information acquired by the road type fault detection device sensing the vehicle in the road type fault detection device array 100, and if so, determines that the vehicle sensed by the road type fault detection device sensing the vehicle has a fault.

Specifically, the preset model data may include a preset duration, when the road fault detection device senses that a vehicle passes through and acquires the running duration of the vehicle (i.e., the time required for the vehicle to pass through the road fault detection device), the running duration may be matched with the preset duration in the preset model data, and if the running duration of the vehicle is less than or equal to the preset duration, the vehicle may be considered to be in a normal running state; if the running time of the vehicle is longer than the preset time, the vehicle can be considered to be in an abnormal running state, such as slow running or stop running, and at the moment, the vehicle can be considered to be in a fault. In addition, the preset model data can contain more than one preset time, the severity level of the fault can be determined according to the time interval in which the running time of the vehicle falls, the longer the time is, the higher the severity level of the fault is, and otherwise, the lower the severity level of the fault is.

In the embodiment of the application, when it is determined that a fault occurs in a vehicle according to the driving state information of the vehicle acquired by a certain road fault detection device, the road fault detection device may be controlled to send out the traffic prohibition optical signal or the traffic warning optical signal. In addition, along the driving direction of the traffic lane where the road surface type fault detection device is located, the road surface type fault detection device within a preset distance behind the road surface type fault detection device can be controlled to send out the same indicating light signal. The preset distance may be a fixed distance value, or may be set according to a fault severity level, where the higher the fault severity level is, the larger the preset distance is, and otherwise, the smaller the preset distance is. The road type fault detection device can determine whether to send out the traffic prohibition optical signal or the traffic warning optical signal according to the severity level of the fault, if the severity level of the fault is high, the traffic prohibition optical signal can be sent out, and if the severity level of the fault is low, the traffic warning optical signal can be sent out. The severity level of the fault may be determined according to which preset speed interval in the preset model data the driving speed included in the driving state information acquired by the road fault detection device is located or which preset time interval in the preset model data the driving time included in the acquired driving state information is located. The severity level of the fault can be represented by a number, such as a high level represented by the number "1", where traffic congestion can be considered severe; the middle level is indicated by the number "2", at which time traffic may be considered sluggish; the low grade is indicated by the number "3" and at this point traffic unblocking can be considered. The severity level of the fault can also be indicated by letters, such as the letter "A" indicating a high level, i.e., severe traffic congestion; the letter "B" represents a medium level, i.e., traffic slowdown; the letter "C" is used to denote a low grade, i.e., traffic jam. It should be understood that, in the embodiment of the present application, the road surface type fault detection device within the rear preset distance sends out the same optical signal as the road surface type fault detection device which senses the fault, but is not limited to this, and the distance between the road surface type fault detection device which senses the fault and the road surface type fault detection device which senses the fault may be determined according to the length of the distance, for example, when the road surface type fault detection device which senses the fault sends out the light signal for prohibiting the passage of light, a part of the road surface type fault detection device which is close to the road surface type fault detection device may also send out the light signal for prohibiting the passage of light, and a part of the road surface type fault detection device which is far from the road surface type fault detection device may send out the light signal for.

Optionally, when it is determined that no vehicle passes through the traffic lane yi adjacent to the traffic lane xi and having the opposite driving direction, the fault emergency processing system of step 730 may control the first light emitting device of the partial or all of the road surface type fault detection devices in the traffic lane yi to emit the light signal for prohibiting passing of traffic, and control the second light emitting device of the partial or all of the road surface type fault detection devices to emit the light signal for allowing passing of traffic, including the following steps:

73) the fault emergency processing system determines a fault severity level according to the acquired running state information, judges whether the fault severity level reaches a preset level, controls a first light-emitting device of a partial or all road surface type fault detection device in a traffic lane yi adjacent to the traffic lane xi and opposite in running direction to emit a light signal for forbidding traffic and controls a second light-emitting device of the partial or all road surface type fault detection device to emit a light signal for allowing traffic if the fault severity level reaches the preset level and determines that no vehicle passes through the traffic lane yi in the traffic lane xi.

Specifically, the road-type fault detection device on the traffic lane yi is allowed to be regulated to change the driving direction of the traffic lane yi under the condition that the fault severity level on the traffic lane xi reaches the preset level and the traffic lane yi is free, otherwise, the driving direction of the traffic lane yi is not changed. For example, when the severity level of the fault reaches a high level, which indicates that traffic congestion on the traffic lane xi is severe, the road-type fault detection device in the traffic lane yi is allowed to be controlled only when the traffic lane yi is idle. When the fault on the traffic lane xi is relieved or relieved (e.g., the fault severity level is lowered below the preset level), the first light-emitting device of the partial or all of the road surface type fault detection devices in the traffic lane yi may be controlled to change from emitting the light signal for prohibiting passage of traffic to emitting the light signal for permitting passage of traffic, and the second light-emitting device of the partial or all of the road surface type fault detection devices may be controlled to change from emitting the light signal for permitting passage of traffic to emitting the light signal for prohibiting passage of traffic or to be extinguished.

Optionally, the fault emergency processing method described in fig. 7 may further include the following steps:

74) when the fault emergency processing system determines that no fault occurs in the vehicles sensed by each road surface type fault detection device in the road surface type fault detection device array 100, the fault emergency processing system controls the first light-emitting device of each road surface type fault detection device in the road surface type fault detection device array 100 to send out an optical signal for allowing the vehicle to pass through, and controls the second light-emitting device of each road surface type fault detection device in the road surface type fault detection device array 100 to send out an optical signal for forbidding the vehicle to pass through.

Specifically, when the driving state information of the vehicle acquired by each road fault detection device in the road fault detection device array 100 is matched with the preset model data, that is, no fault occurs on both lanes, the traffic condition may be considered to be good at this time, and therefore, the first light emitting devices of all the road fault detection devices may be controlled to emit the permission light signal and the second light emitting devices may be controlled to emit the prohibition light signal or be turned off. Alternatively, when the trouble on the traffic lane in which the trouble has occurred is resolved, the light signal emitted from the road-type trouble detecting device on the traffic lane may be controlled to be converted from the passage-prohibition light signal (or the passage-warning light signal) into the passage-permission light signal.

It can be seen that, in the embodiments of the present application, a plurality of road surface type fault detection devices are laid on the road surfaces of two adjacent lanes of a road, where the driving directions of the two adjacent lanes are opposite to each other, to form a road surface type fault detection device array, a fault emergency processing system senses and obtains driving state information of a passing vehicle by using the road surface type fault detection device array, and analyzes the obtained driving state information to determine whether a sensed vehicle has a fault (such as vehicle stop or slow driving), if the vehicle has the fault, determines a lane where the fault exists, controls a first light emitting device of the road surface type fault detection device that senses the fault exists to emit a no-pass light signal or a warning pass light signal, and controls a first light emitting device of the road surface type fault detection device that senses the fault within a preset distance behind the road surface type fault detection device that senses the fault to emit the same light signal as the road surface type fault detection device that senses the fault in the driving direction of the lane where the fault exists (ii) a Further, when it is determined that no vehicle passes through a traffic lane adjacent to the failed traffic lane and having an opposite traveling direction, it is possible to control a part or all of the first light emitting devices of the road surface type failure detecting means in the adjacent traffic lane to emit a light signal for prohibiting passage of traffic, and to control a part or all of the second light emitting devices of the road surface type failure detecting means to emit a light signal for permitting passage of traffic. Therefore, traffic faults on urban roads or expressways can be intelligently monitored in real time, corresponding indication light signals are sent out by controlling the road fault detection device, and vehicles behind can be timely notified, so that the vehicles behind can be decelerated in advance or the vehicles behind can be switched to go out to avoid obstacles; in addition, when the adjacent traffic lane is idle, the driving direction of the adjacent traffic lane can be changed by controlling the road fault detection device on the adjacent traffic lane, so that the vehicle on the traffic lane with the fault passes through the adjacent traffic lane, and the passing efficiency of the vehicle can be improved. In addition, the system is applied to the road sections with multiple accidents, and the traffic efficiency and the safety performance can be improved.
