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.

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 information can be stored in the storage module, so that the accident occurrence position 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 certain 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 can be controlled to send out the light signal for prohibiting passing from the first side surface, and at this time, the rear vehicle on the entrance lane 1 cannot pass on the entrance lane 1 continuously, and can change the lane to pass on the entrance lane 2. 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.
Optionally, 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, the vehicle monitoring node, the storage module, and the communication module, 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, the vehicle monitoring node, the storage module, and the communication module. 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 road fault detection device 10 shown in fig. 5a and 5b may further include a solar cell panel 131 and a third protection cover 132 besides the structure described in fig. 3a and 3b, 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 with the control circuit board, the vehicle monitoring node, the storage module and the communication module respectively, and is used for providing electric energy for the control circuit board, the vehicle monitoring node, the storage module and the communication module.
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 device in some embodiments of the present application includes a main housing, a control circuit board, a vehicle monitoring node, a storage module, a communication module, a first light emitting device and a first 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 the passing vehicle has a fault, the first light emitting device is disposed on one side of the main housing, and the first light emitting device is connected to the control circuit board and controlled by the control circuit board, so that the first 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 on a certain lane detects that the passing vehicle has a fault or delays the passing, the control circuit board can control the first light emitting device to emit a no-pass or warning-pass light signal, prompting the rear vehicle to prohibit the vehicle from advancing on the lane, so that the rear vehicle can change lanes in advance to avoid the 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. 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.

Specifically, the control circuit board of the road surface type fault detection device i may send the control information to the communication module of another road surface type fault detection device through the communication module, so that the control circuit board of the road surface type fault detection device controls the first light emitting device to emit the second indication light signal according to the indication of the control information. The control circuit board of the road surface type fault detection device i can send control information to the next adjacent road surface type fault detection device and enable the control information to be responded, the next road surface type fault detection device sends the control information to the next adjacent road surface type fault detection device and enables the next road surface type fault detection device to respond, and therefore the road surface type fault detection devices within the first preset distance can receive the control information one by one and respond. In addition, the control circuit board of the road fault detection device i may also send the control information to all the road fault detection devices within the first preset distance in a broadcast manner, so that all the road fault detection devices within the first preset distance receive the control information and respond.
The fault severity level can be divided into at least two levels, the fault severity level can be represented by a number, for example, a high level is represented by a number "1", and at this time, the traffic congestion can be considered to be serious; 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.
Specifically, the first indicating light signal may include a no-go light signal or a warning-go light signal, and the first indicating light signal may be determined by the severity level of the fault. When the severity level of the fault is higher, the first indicating light signal can be a light signal for forbidding to pass (for example, emitting red light), and when the severity level of the fault is lower, the first indicating light signal can be a light signal for warning to pass (for example, emitting yellow light). The first predetermined distance is associated with a fault severity level, and the first predetermined distances corresponding to different fault severity levels may be the same or different. The first predetermined distance may be larger when the fault severity level is higher, and may be smaller when the fault severity level is lower, such as the first predetermined distance being 50 meters, 60 meters, 75 meters, 90 meters, 100 meters, or other values. The second indicating light signal is also associated with a fault severity level, and may be an optical signal for inhibiting passage or an optical signal for warning passage when the first indicating light signal is determined to be an optical signal for inhibiting passage by the fault severity level, for example, the second indicating light signal is an optical signal for inhibiting passage (e.g., emitting red light) when the fault severity level is high, and the second indicating light signal is an optical signal for warning passage (e.g., emitting yellow light) when the fault severity level is low. When the first indicating optical signal is determined to be the warning traffic optical signal according to the fault severity level, the second indicating optical signal may also be the warning traffic optical signal. The road surface type fault detection device in a certain distance of the accident road section is controlled to send out an indicating light signal, so that a driver of a vehicle behind can visually know the traffic road condition in front, and the vehicle can timely decelerate or change the road to drive according to the road condition.
Optionally, the control circuit board of the road-type fault detection device i may be specifically configured to match the driving state information with preset model data stored in the storage module, determine whether a driving speed included in the driving state information is within one of preset speed intervals included in the preset model data, if so, determine that a fault occurs on a lane xi, determine a fault severity level according to a preset speed interval to which the driving speed included in the driving state information belongs, control a first light-emitting device of the road-type fault detection device i to emit a first indication light signal corresponding to the fault severity level, and send first control information to a road-type fault detection device within a first preset distance behind the road-type fault detection device i along a driving direction of the lane xi, so as to control the first light-emitting devices of the road-type fault detection devices to emit second indication light signals corresponding to the fault severity level; or, the control circuit board of the road fault detection device i may be specifically configured to match the driving state information with preset model data stored in the storage module, determine whether the driving time included in the driving state information is within one of preset time intervals included in the preset model data, if so, determining that the fault occurs on the traffic lane xi, determining the severity level of the fault according to the preset time interval to which the running time included in the running state information belongs, and controls a first light emitting device of the road-type fault detection device i to emit a first indicating light signal corresponding to the severity level of the fault, and along the driving direction of the traffic lane xi, sending first control information to a road surface type fault detection device within a first preset distance behind the road surface type fault detection device i, so as to control the first light-emitting device of the road surface type fault detection devices to emit a second indicating light signal corresponding to the severity level of the fault.
The storage module of the road fault detection device i may store a preset data model in advance, and the preset data model may include, but is not limited to, different preset speed intervals, different preset duration intervals, a preset driving direction and other information. When the driving state information acquired by the vehicle monitoring node of the road fault detection device i includes the driving speed of the vehicle, the control circuit board of the road fault detection device i can compare the driving speed with each preset speed interval in the preset data model to judge whether the driving speed falls into one of the preset speed intervals, and if the driving speed does not fall into any preset speed interval, the vehicle can be considered to be currently and normally driven, and no fault occurs on a driving lane xi; if the driving speed falls into one of the preset speed intervals, it can be considered that a fault occurs on the current driving lane xi, and the fault severity level of the accident is determined according to the preset speed interval in which the driving speed falls, so that the first light-emitting device of the road surface type fault detection device i is controlled to emit a corresponding indicating light signal according to the fault severity level. For example, the smaller the speed value included in the preset speed interval is, the larger the fault severity level is, and the larger the speed value included in the preset speed interval is, the smaller the fault severity level is. Or, when the driving state information acquired by the vehicle monitoring node of the road fault detection device i includes the driving time length of the vehicle, the control circuit board of the road fault detection device i may compare the driving time length with each preset time length interval in the preset data model to determine whether the driving time length falls into one of the preset time length intervals, and if the driving time length does not fall into any one of the preset time length intervals, it may be determined that the vehicle is currently and normally driven and no fault occurs on the driving lane xi; if the running time length falls into one of the preset time length intervals, the fault on the current running lane xi can be considered to occur, the fault severity level of the accident is determined according to the preset time length interval in which the running time length falls, and then the first light-emitting device of the road surface type fault detection device i is controlled to emit corresponding indicating light signals according to the fault severity level. For example, the smaller the duration value included in the preset duration interval is, the smaller the severity level of the fault is, and the larger the duration value included in the preset duration interval is, the larger the severity level of the fault is.
Optionally, the control circuit board of the road surface type fault detection device i may be further configured to send second control information to the road surface type fault detection device within a range from the first preset distance to a second preset distance behind the road surface type fault detection device i when it is determined that a fault occurs on the traffic lane xi, so as to control the first light emitting device of the road surface type fault detection device within the range from the first preset distance to the second preset distance behind the road surface type fault detection device i to send a third indicating light signal corresponding to the fault severity level, where the second preset distance is determined by the fault severity level.
The second preset distances corresponding to different fault severity levels may be the same or different. The second predetermined distance may be larger when the fault severity level is higher, and may be smaller when the fault severity level is lower, such as 20 meters, 30 meters, 50 meters, 65 meters, 70 meters, or other values. The third indicating light signal is also associated with a fault severity level, and may be an optical signal for inhibiting passage or an optical signal for warning passage when the second indicating light signal is determined to be an optical signal for inhibiting passage by the fault severity level, for example, the third indicating light signal is an optical signal for inhibiting passage (e.g., emitting red light) when the fault severity level is high, and the third indicating light signal is an optical signal for warning passage (e.g., emitting yellow light) when the fault severity level is low. The third indicating light signal may be a warning light signal or a clear light signal when the fault severity level determines that the second indicating light signal is a warning light signal, for example, the third indicating light signal is a warning light signal (e.g., emitting yellow light) when the fault severity level is high, and the third indicating light signal is a clear light signal (e.g., emitting green light) when the fault severity level is low. The road surface type fault detection devices which control a certain number of road surface type fault detection devices in a segmented mode can reflect the traffic road conditions more visually and more accurately, and give drivers of rear vehicles sufficient reaction time.

In practical application, when no fault occurs on a traffic lane, each road type fault detection device on the traffic lane can be controlled to send out a light signal allowing traffic; alternatively, when the trouble occurring in the traffic lane is resolved, the road-type trouble detecting device on the traffic lane may be controlled to switch from emitting the light signal for prohibiting the passage of traffic or the light signal for warning the passage of traffic to emitting the light signal for permitting the passage of traffic.
Optionally, the road surface type fault detection apparatus i may further include a second light emitting device 121 and a second protective cover 122, a second receiving cavity 123 for receiving the second light emitting device 121 is disposed on a 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 sealed 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 respectively and 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 of the main housing 110 are two opposite sides of the main housing 110.

In practical applications, the advantage of using the array of road fault detection devices is that when one of the road fault detection devices fails to work normally due to damage, the detection of the traffic fault is not adversely affected, that is, even if one or some of the road fault detection devices fails to work, other undamaged road fault detection devices can still be used to monitor the traffic status normally.
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. As shown in fig. 6, a road may include a roadbed (not shown in the figure) and a road surface provided on the roadbed, wherein the roadbed may be regarded as a foundation of the road and is located below the road surface, and the road surface is laid above the roadbed for vehicles to travel.

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.
It can be seen that the intelligent fault detection and emergency processing system provided by the embodiment of the present application includes a road fault detection device array formed by a plurality of road fault detection devices laid on a lane, wherein any two adjacent road fault detection devices are in communication connection, when the road fault detection device senses a passing vehicle and acquires running state information of the passing vehicle, the road fault detection device can determine whether a fault occurs on the current lane (such as vehicle stop or slow running, etc.) according to the running state information, and if so, can further determine a fault severity level, the road fault detection device controls itself to send out a first indication light signal corresponding to the fault severity level, and sends control information to the road fault detection device within a first preset distance behind the road fault detection device along the running direction of the lane, so as to control the road surface type fault detection devices to send out second indication optical signals corresponding to the severity level of the fault.
