The embodiment of the application provides a road surface type fault detection device, a vehicle-road interactive type fault detection and emergency processing system and method.

The terms "comprising" and "having," and any variations thereof, as appearing in the specification, claims and drawings of this application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. Furthermore, the terms "first," "second," and "third," etc. are used to distinguish between different objects and are not used to describe a particular order. Some related terms are first explained below by way of example.

The embodiment of the application provides a road surface type fault detection device 10.

Referring to fig. 1a to fig. 1c, in which, fig. 1a is a schematic top view of a road fault detection device according to an embodiment of the present disclosure; fig. 1b is a schematic top view of a main housing of the pavement fault detection apparatus illustrated in fig. 1a according to an embodiment of the present disclosure; fig. 1c is a schematic front view of the pavement fault detection apparatus illustrated in fig. 1a according to an embodiment of the present application.

The road surface type fault detection device 10 may include: the vehicle monitoring system comprises a main shell 110, a control circuit board (not shown in the figure), a vehicle monitoring node (not shown in the figure), a first light-emitting device 111 and a first protective cover 112, wherein the control circuit board is connected with the vehicle monitoring node, the vehicle monitoring node is used for sensing a passing vehicle and acquiring running state information of the passing vehicle, and the area of the bottom surface of the main shell 110 is larger than or equal to that of the top surface of the main shell 110;

a first accommodating cavity 113 for accommodating the first light emitting device 111 is formed in the first side surface of the main housing 110, the first protecting cover 112 covers an opening surface of the first accommodating cavity 113 for accommodating the first light emitting device 111, a sealing and waterproof structure is formed between the opening surface of the first accommodating cavity 113 and the first protecting cover 112 in a matching manner, the first light emitting device 111 is connected with the control circuit board, and a light signal emitted by the first light emitting device 111 can partially or completely penetrate through the first protecting cover 112;

the main housing 110 is further provided with a fourth receiving cavity (not shown) for receiving the control circuit board.

Optionally, the first protective cover 112 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.

Alternatively, the bottom surface of the main housing 110 may be rectangular or square, or other regular/irregular shapes, etc.

Optionally, the fourth accommodating cavity may be disposed on the bottom surface of the main housing 110, and the pavement fault detection apparatus 10 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, the fourth accommodating cavity accommodating the control circuit board may be filled with waterproof sealing mastic.

Optionally, the vehicle monitoring node may include, but is not limited to, at least one of a geomagnetic sensor, a piezoelectric sensor (e.g., a gravity sensor), a photoelectric sensor (e.g., a laser sensor, an infrared sensor, etc.), an ultrasonic sensor, and a capacitive sensor. The vehicle monitoring node is used for sensing a vehicle running on a road, and can detect running state information of the vehicle at the same time, wherein the running state information of the vehicle can include but is not limited to running speed, running time, running direction, running position and the like when the vehicle passes through the vehicle monitoring node. Specifically, when a vehicle runs on a road, a signal of the sensor changes when the vehicle passes through the sensor, so that the sensor senses that the vehicle passes through. For example, a vehicle passing by a geomagnetic sensor may cause a change in the magnetic field around the sensor; when the vehicle passes through the piezoelectric sensor, the sensor can sense the pressure exerted on the sensor by the vehicle; when a vehicle passes through the photoelectric sensor, the sensor senses that the ambient illumination intensity changes, or receives a reflected light signal when the vehicle passes through the photoelectric sensor; when the vehicle passes through the ultrasonic sensor, the sensor receives the reflected ultrasonic signal; a vehicle passing a capacitive sensor may cause the sensor to sense a change in capacitance due to pressure exerted thereon by the vehicle, and so on.

Alternatively, the vehicle monitoring node may be separately disposed outside the main housing 110, or the vehicle monitoring node may be packaged inside the main housing 110, or the vehicle monitoring node may be disposed on the surface of the main housing 110. Specifically, when the vehicle monitoring node is disposed outside the main housing 110, the vehicle monitoring node may be located beside the main housing 110, and the vehicle monitoring node and the control circuit board may be wired through a waterproof wire hole on the bottom plate for communication connection, and at this time, the vehicle monitoring node may be partially or completely buried under the road surface. When the vehicle monitoring node is housed inside the main housing 110, the vehicle monitoring node may be partially or fully housed within the main housing 110. When the vehicle monitoring node is disposed on the surface of the main housing 110, the vehicle monitoring node may be attached to one or any one of the side surfaces of the main housing 110, or attached to the top surface of the main housing 110.

In the embodiment of the present application, the first light emitting device 111 can send out the optical signal for allowing the light to pass under the control of the control circuit board, and the first light emitting device 111 can also send out the optical signal for prohibiting the light to pass under the control of the control circuit board; alternatively, the first light emitting device 111 can send out the enable light signal under the control of the control circuit board, the first light emitting device 111 can also send out the disable light signal under the control of the control circuit board, and the first light emitting device 111 can also send out the warning light signal under the control of the control circuit board.

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.

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 100 includes 2 entrance lanes and 1 exit lane, and the 2 entrance lanes and the 1 exit lane converge in the intersection region, that is, the exits of the 2 entrance lanes are connected to the entrances of the intersection region, the entrances of the exit lanes are connected to the exits of the intersection region, and the traveling directions of the 2 entrance lanes are different. The plane intersection 200 includes 2 entrance lanes and 1 exit lane, and the 2 entrance lanes and 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 100 and the plane intersection 200, 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 100 and/or the plane intersection 200 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.

Referring to fig. 3a and fig. 3b together, fig. 3a is a schematic top view of another pavement fault detection apparatus according to an embodiment of the present disclosure; fig. 3b is a schematic top view of a main housing of the pavement fault detection apparatus illustrated in fig. 3a according to an embodiment of the present disclosure. The road fault detection apparatus 10 shown in fig. 3a and 3b may further include a second light emitting device 121 and a second protective cover 122 besides the structures described in fig. 1a to 1c, a second receiving cavity 123 for receiving the second light emitting device 121 is disposed on the second side surface of the main housing 110, the second protective cover 122 covers an opening surface of the second receiving cavity 123 for receiving the second light emitting device 121, a sealing and waterproof structure is formed between the opening surface of the second receiving cavity 123 and the second protective cover 122 in a matching manner, the second light emitting device 121 is connected to the control circuit board, the first light emitting device 111 and the second light emitting device 121 are independently controlled by the control circuit board, and an optical signal emitted by the second light emitting device 121 can partially or completely penetrate through the second protective cover 122;

the first side and the second side are two opposite sides of the main housing 110.

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 traffic lanes with opposite traveling directions, such as the entrance lane 1 and the exit lane 2 adjacent to the entrance lane 1, and when a fault occurs on the entrance lane 1, the second light emitting device 121 of the road fault detection device 10 on the exit lane 2 can emit a clear light signal (e.g., the second light emitting device 121 emits green light) when the exit lane 2 is empty, so that the vehicle on the entrance lane 1 can pass through the exit lane 2, and the traveling direction of the exit lane 2 will be opposite to the original traveling direction, i.e., the traveling direction of the entrance lane 1 is the same; when the fault on the entrance lane 1 is resolved, the second light emitting device 121 of the road fault detection apparatus 10 on the exit lane 2 may emit a light signal for prohibiting passage (for example, the second light emitting device 121 emits red light), that is, the vehicle on the entrance lane 1 is prohibited from passing through the exit lane 2; 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 apparatus 10 on the exit lane 2 may also emit a warning passage light signal (e.g., the second light emitting device 121 emits yellow light), which may prompt the vehicle to be changed on the entrance 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.

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 surface type fault detection device, and a plurality of or all of the road surface type fault detection devices on one entrance lane (or exit lane) may be regarded as a road surface type fault detection device array. The main housing of any one of the road surface type fault detection devices may be partially or completely 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 in the road surface type fault detection device array on any entrance lane (or exit lane) can be equal or partially equal or different. For example, the spacing between any two adjacent road surface fault detection devices 10 in the array of road surface fault detection devices 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 in the array of road surface type failure detection devices gradually decreases; alternatively, the spacing between two adjacent road surface type failure detection devices 10 in the array of road surface type failure detection devices gradually increases in the traveling direction of the entrance lane (or the exit lane). Of course, the spacing between two adjacent sensors in the array of pavement-type fault detection devices may also be varied randomly or in other ways, and does not necessarily exhibit the above-mentioned exemplary gradually decreasing or gradually increasing variation 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. 5a and 5b together, fig. 5a is a schematic top view of a pavement fault detection apparatus according to an embodiment of the present disclosure; fig. 5b is a schematic top view of a main housing of the pavement fault detection apparatus illustrated in fig. 5a according to an embodiment of the present disclosure.

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.

The traffic state on the road is automatically monitored through the vehicle monitoring node, and the traffic of the vehicle behind is indicated through the indicating light signal sent by the first light-emitting device, so that a certain hardware foundation can be laid for timely obstacle avoidance when the vehicle runs on the road, and particularly, the road type fault detection device is applied to a road section with multiple accidents, and the traffic efficiency and the traffic safety performance can be improved.

In addition, in some embodiments of the present application, the road-type fault detection apparatus may further include a second light emitting device disposed opposite to the first light emitting device, and/or a solar cell panel disposed on the top surface of the main housing; the driving direction of the traffic lane can be changed by adjusting the first light-emitting device and the second light-emitting device, so that the requirement of bidirectional indication can be met. In addition, solar energy is converted into electric energy through the solar cell panel to supply power to each functional module in the road surface type fault detection device, so that the road surface type fault detection device can work normally, and the problem that the road surface type fault detection device needs to replace batteries frequently due to limited battery storage is solved.

The road-based fault detection device 10 may have at least one wireless and/or wired control signal input interface such that the road-based fault detection device 10 may establish a communication connection with the control signal output interface of the signal controller 20 in a wireless and/or wired manner.

It is understood that the back office management center 30 may be a traffic control center, a server, a service desk, etc. of a traffic management department.

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 pavement fault detection apparatus 10 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.

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.

Optionally, the signal controller 20 may be further configured to, after receiving the fault feedback information, control the first light emitting device of the road surface type fault detection apparatus that sends the fault feedback information to send an optical signal for prohibiting passage of traffic, and control the first light emitting device of the road surface type fault detection apparatus that is within a preset distance behind the road surface type fault detection apparatus that sends the fault feedback information to send an optical signal for prohibiting passage of traffic along the traveling direction of the lane; alternatively, the signal controller 20 may be further configured to control the first light emitting device of the road surface type fault detection apparatus that transmits the fault feedback information to emit the warning traffic light signal after receiving the fault feedback information, and to control the first light emitting device of the road surface type fault detection apparatus that transmits the fault feedback information within a preset distance from the road surface type fault detection apparatus to emit the warning traffic light signal along the traveling direction of the lane.

Wherein each of the road-type failure detection apparatuses 10 on the traffic lane is operable under the driving control of the signal controller 20. Specifically, when the signal controller 20 receives the feedback information and analyzes that the feedback information sent by the road fault detection device 10 is not matched with the preset model, if the running speed in the feedback information is lower than the preset speed, or the running time in the feedback information exceeds the preset time, it may be determined that a vehicle on the lane has a fault such as stopping or slow running. Further, the signal controller 20 may control the first light emitting device 111 of the road fault detection apparatus 10 with the feedback fault to emit the light signal for prohibiting passing or the light signal for warning passing, and may control all or a certain number of the first light emitting devices 111 of the road fault detection apparatus 10 at a certain distance behind the road fault detection apparatus 10 to emit the light signal for prohibiting passing or the light signal for warning passing along the traveling direction of the lane, so that the following vehicles can timely avoid the obstacle or change the lane according to the indication light signal.

In addition, whether the first light emitting device 111 emits the light signal for prohibiting passage or the light signal for warning passage may be determined according to the severity level of the failure, and if the severity level of the failure is high, the light signal for prohibiting passage may be emitted, and if the severity level of the failure is low, the light signal for warning passage may be emitted. And the fault severity level can be determined according to which preset speed interval or duration interval the running speed or running duration of the vehicle falls.

In addition, when a vehicle on a lane adjacent to and opposite to the lane is in an accident and the lane is idle, the signal controller 20 may control all or a part of the first light emitting devices 111 of the road fault detection devices 10 on the lane to emit a no-passing light signal or to be turned off, and control the second light emitting devices 121 of the road fault detection devices 10 to emit a no-passing light signal, so as to allow the vehicle running on the lane in which the accident occurs to pass through the lane, thereby alleviating traffic paralysis caused by the accident. Of course, the above control process is also applicable to a tidal lane, i.e., the driving direction of the tidal lane is adjusted by controlling the first light emitting device 111 and the second light emitting device 121 of the road-type malfunction detection apparatus 10 on a certain lane.

Therefore, traffic faults on urban roads or expressways can be intelligently monitored in real time, the faults are sent to the vehicle-mounted terminal in a broadcasting mode to achieve vehicle-road interaction, and vehicles behind can be timely informed to change lanes to go out to avoid obstacles. 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. 7, the road with the fault detection function may include a roadbed (not shown in the figure) and a road surface arranged on the roadbed, wherein a traffic lane is arranged on the road surface, a groove is formed in the traffic lane, and any one of the road surface type 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. Furthermore, at least one traffic lane can be arranged on the road surface, the traffic lane can be an entrance lane or an exit lane of a certain plane intersection on the road, and the driving directions of vehicles are opposite when the vehicles drive in the entrance lane and the exit lane.

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 20 may be disposed at the roadside of the traffic lane, and the signal controller 20 establishes a wired and/or wireless connection with each road fault detection device 10 disposed on the traffic lane, respectively, so as to realize communication interaction between the signal controller 20 and any one of the road fault detection devices 10. The back office management center 30 may be disposed beside the road or indoors, which is not limited herein.

The vehicle-road interactive fault detection and emergency processing method can be applied to the vehicle-road interactive fault detection and emergency processing system disclosed by the embodiment. Referring to fig. 8, the method for interactive fault detection and emergency handling for a vehicle road may include the following steps:

810. the fault detection and emergency processing system senses passing vehicles on a lane of a road by using at least one road-type fault detection device and acquires running state information of the passing vehicles.

Wherein, above-mentioned at least one road surface formula fault detection device sets up on the ground of this traffic lane. Specifically, the housing of one or any one of the at least one road fault detection device may be partially buried under the road surface of the traffic lane, or the housing of one or any one of the at least one road fault detection device 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 may be used to sense a passing vehicle on a traffic lane and acquire driving state information of the passing vehicle, wherein the vehicle monitoring node may include, but is not limited to, at least one of a geomagnetic sensor, a piezoelectric sensor (e.g., a gravity sensor), a photoelectric sensor (e.g., a laser sensor, an infrared sensor, etc.), 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, and the like when the vehicle passes through the road fault detection device.

820. And the fault detection and emergency processing system determines whether a fault occurs on the traffic lane according to the driving state information acquired by the road fault detection device sensing the vehicle in the at least one road fault detection device.

830. And when the fault detection and emergency processing system determines that the fault occurs on the lane, the fault detection and emergency processing system broadcasts fault feedback information to the vehicle-mounted terminal.

Optionally, the specific implementation manner of the step 820, in which the fault detection and emergency processing system determines whether a fault occurs on the traffic lane according to the driving state information acquired by the road fault detection device sensing the vehicle from the at least one road fault detection device, may include the following steps:

81) and the fault detection and emergency processing system judges whether the running speed included in the obtained running state information is lower than a preset speed or not according to the running state information obtained by the road type fault detection device sensing the vehicle in the at least one road type fault detection device, and if the running speed is lower than the preset speed, the fault on the running lane is determined.

Specifically, the model data may be stored in advance, where the model data may include a preset speed, when the road fault detection device senses that a vehicle passes through and obtains the running speed of the vehicle, the running speed may be matched with the preset speed in the 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. In addition, the 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.

82) and the fault detection and emergency processing system judges whether the running time included in the obtained running state information is longer than the preset time according to the running state information obtained by the road type fault detection device sensing the vehicle in the at least one road type fault detection device, and if so, determines that a fault occurs on the running lane.

Specifically, the pre-stored 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 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. In addition, the model data may include more than one preset time duration, and the severity level of the fault may be determined according to a time duration interval in which the driving time duration of the vehicle falls, wherein the longer the time duration is, the higher the severity level of the fault is, and conversely, the lower the severity level of the fault is.

In the embodiment of the application, when it is determined that a fault occurs on the traffic lane according to the driving state information of the vehicle, the fault feedback information can be sent to the vehicle-mounted terminal installed on the vehicle driving on the road in a broadcasting manner. The fault feedback information may include, but is not limited to, location information of the fault, severity level of the fault, time of occurrence of the fault, safety speed prompt information, and the like. After receiving the fault feedback information, the vehicle can timely know the traffic condition on the road ahead, and can timely make corresponding countermeasures according to the prompt of the fault feedback information, such as changing a traffic lane in advance or reducing the driving speed to be within a safe speed range, and the like.

Optionally, the vehicle-road interactive fault detection and emergency processing method described in fig. 8 may further include the following steps:

83) when the fault detection and emergency processing system determines that a fault occurs on the traffic lane, the fault detection and emergency processing system controls the road surface type fault detection device sensing the vehicle to send out a light signal for forbidding traffic, and controls the road surface type fault detection device sensing the vehicle within a preset distance behind the road surface type fault detection device to send out a light signal for forbidding traffic along the running direction of the traffic lane; or,

84) when the fault detection and emergency processing system determines that a fault occurs on the traffic lane, the fault detection and emergency processing system controls the road surface type fault detection device sensing the vehicle to send out a warning traffic light signal, and controls the road surface type fault detection device sensing the vehicle within a preset distance behind the road surface type fault detection device to send out the warning traffic light signal along the running direction of the traffic lane.

Specifically, when it is determined that the vehicle has a fault 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 an optical signal for prohibiting traffic or an optical signal for warning traffic. In addition, along the driving direction of the lane, 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 a traffic prohibition light signal or a traffic warning 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 road surface type failure detection device within the predetermined rear distance may emit the same optical signal as the road surface type failure detection device that senses the failure, or may be determined according to the distance from the road surface type failure detection device that senses the failure, for example, when the road surface type failure detection device that senses the failure emits the light signal for prohibiting passage of light, a part of the road surface type failure detection device near the road surface type failure detection device may also emit the light signal for prohibiting passage of light, and a part of the road surface type failure detection device far from the road surface type failure detection device may emit the light signal for warning passage of light.

85) and when the fault detection and emergency processing system determines that no fault occurs on the traffic lane, the fault detection and emergency processing system controls all the road type fault detection devices on the traffic lane to send out light signals allowing traffic.

Specifically, when the driving state information of the vehicle acquired by each road surface type fault detection device on the traffic lane is matched with the model data, that is, when no fault occurs on the traffic lane, the traffic condition can be considered to be good at this time, and therefore all the road surface type fault detection devices on the traffic lane can be controlled to send out the light signal allowing traffic. Alternatively, when the fault on the traffic lane is resolved, the optical signals emitted by all the road fault detection devices on the traffic lane may be controlled to be converted from the traffic-restricted optical signal (or the warning traffic optical signal) into the traffic-permitted optical signal.

It can be seen that, in the embodiment of the present application, at least one road-type fault detection device is laid on a road surface of a lane of a road, and the interactive vehicle-road fault detection and emergency processing system senses and acquires driving state information of a passing vehicle by using the at least one road-type fault detection device, and analyzes the acquired driving state information to determine whether a fault occurs on the lane (such as vehicle stopping or slow driving), and if a fault occurs on the lane, broadcasts fault feedback information to each vehicle-mounted terminal on the lane, such as broadcasting information of a fault location, a fault severity level, and the like to each vehicle-mounted terminal. Therefore, traffic faults on urban roads or expressways can be intelligently monitored in real time, the faults are sent to the vehicle-mounted terminal in a broadcasting mode to achieve vehicle-road interaction, and vehicles behind can be timely informed of the occurrence of lane changing to avoid obstacles. In addition, the system is applied to the road sections with multiple accidents, and the traffic efficiency and the safety performance can be improved.
