[0090] The function of the laser transmitter Ⅰ5 and the laser receiver Ⅰ10 is to sense the target (vehicle) and then send the sensing result to the main controller Ⅰ4; specifically, when the vehicle passes by and blocks the laser beam 19, the main controller Ⅰ4 is triggered, and the main controller Ⅰ4 controls the LED light source controller Ⅱ11 to control the color of the LED light source 16 on the intelligent road stud host to change (strobe)

[0091] The main controller Ⅰ4 communicates with the main controller Ⅱ12 through the intelligent communicator Ⅰ7 and the intelligent communicator Ⅱ13. The main controller Ⅱ12 controls the LED light controller Ⅰ2 to change the color (strobe) of the LED light 16 on the intelligent road stud slave. At the same time, the intelligent road stud host also communicates with the adjacent intelligent road stud host and intelligent road stud slave through the intelligent communicator Ⅰ7. Thus, the LED light 16 on these devices can be controlled to change color (strobe), which plays a role in vehicle guidance and distance maintenance for the front and rear vehicles.

[0092] The fault diagnosis device I6 can monitor the internal operation faults of the intelligent road stud host in real time, and send the fault data to the remote end through the intelligent communicator I7. The functions of the intelligent communicator I7 are: ① to complete the local communication with the intelligent road stud slave; ② to complete the transmission of fault data to the remote end; ③ to complete the communication between multiple devices in the intelligent road stud layout section.

[0093] The fault diagnosis device II 14 can monitor the internal operation faults of the intelligent road spike slave in real time, and send the fault data to the remote end through the intelligent communicator II 13. The functions of the intelligent communicator II 13 are: ① to complete the local communication with the intelligent road spike host; ② to complete the transmission of fault data to the remote end; ③ to complete the communication between multiple devices in the intelligent road spike deployment section.

[0094] The intelligent road spike host and the intelligent road spike slave of the utility model are both designed to be separated and detachable. The power supply Ⅰ8 is installed in the intelligent road spike host control base Ⅰ23, and the power supply Ⅱ15 is installed in the intelligent road spike slave control base Ⅱ25, which can prevent power supply operation failure from causing damage to the entire intelligent road spike host and the intelligent road spike slave.

[0095] The intelligent road spike host and intelligent road spike slave of the utility model adopt the layout scheme of embedding in the road surface. Among them, the intelligent road spike host control body Ⅰ22 is higher than the road surface, and the intelligent road spike host control base Ⅰ23 is lower than the road surface, and can be separated by M5 bolts 21, which is convenient for debugging the functions of the intelligent road spike host and the intelligent road spike slave, and convenient for maintenance operations. The intelligent road spike slave control body Ⅱ24 is higher than the road surface, and the intelligent road spike slave control base Ⅱ25 is lower than the road surface, and can be separated by M5 bolts 21, which is convenient for debugging the functions of the intelligent road spike host and the intelligent road spike slave, and convenient for maintenance operations.

[0096] In the utility model, the LED light emitting body controller Ⅰ2 and the LED light emitting body controller Ⅱ11 are installed toward the vehicle approaching side.

[0097] In the present invention, the intelligent communicator I7 and the intelligent communicator II13 communicate with each other by wireless communication to achieve synchronization of the flashing frequency of the LED light emitting body 16 .

[0098] In bad weather conditions, the LED lights on the smart road stud master and smart road stud slave in the area in front and behind the vehicle will flash red and regularly to remind the vehicles in front and behind to keep a safe distance. At night, the LED lights will flash to keep the lane and guide the vehicle.

[0099] The temperature and humidity sensor 3 can monitor the real-time data of the road surface temperature and humidity in the road stud deployment area, and then send the data to the remote server for data transmission through the intelligent communicator I 7 using DTU communication.

[0100] Under adverse weather conditions such as low visibility and heavy rain, when a vehicle passes by and blocks the laser beam 19, the monitoring function of the intelligent road stud host is triggered, and it randomly communicates locally with the adjacent intelligent road stud host and intelligent road stud slave, controlling the color of the LED light 16 on these devices to change (strobe), thereby playing a role in guiding the vehicles in front and behind and maintaining the distance between vehicles.

[0101] Smart road studs are installed on the left and right shoulders of highways. Figure 2 The main intelligent road stud is installed on the left side of the road, and the main intelligent road stud is installed on the right side of the road. The installation distance between the main intelligent road studs is 3~5m, and the installation distance between the slave intelligent road studs is 3~5m. The actual installation distance can be dynamically adjusted according to the layout requirements.

[0102] The fault diagnosis device Ⅰ6 in the intelligent road stud host can monitor the current and voltage data of the power supply Ⅰ8 in real time; and monitor the working stability of the laser emitter Ⅰ5 and the temperature and humidity sensor 3 (the working state is judged according to the byte information sent by the laser emitter Ⅰ5 and the temperature and humidity sensor 3 to the main controller Ⅰ4, thereby judging its working stability). When an abnormality is detected, the abnormal data is divided into the format of the fault source information category threshold by the main controller Ⅰ4 to select the target object level (according to Table 1, choose to process locally or remotely) to complete the transmission of the fault source data.

[0103] For example, when the main controller I detects the fault source information of abnormal monitoring data signal transmission, it repairs the fault by self-restart (locally); if it receives the fault source information of abnormal voltage and current data, it completes the remote (remote server) communication through DTU communication and uploads the fault point data.

[0104] For example, the classification of the thresholds of the fault source information detected by the intelligent communicator I is shown in Table 1. The present invention does not limit this, and it can be set according to the actual situation and the existing method.

[0105] Table 1

[0106] Risk Level Fault source information Fault information receiving level Ⅳ Communication lost remote Ⅲ Voltage and current data are abnormal remote Ⅱ Monitoring data signal transmission abnormality local Ⅰ Laser detection signal is abnormal local

[0107] Note: Local refers to the smart road spike host, and remote refers to the remote server.

[0108] The fault diagnosis device Ⅱ14 in the intelligent road stud slave can monitor the current and voltage data of the power supply Ⅱ15 in real time; and monitor the working stability of the laser receiver Ⅰ10 (the working state is determined according to the byte information sent by the laser receiver Ⅰ10 to the main controller Ⅰ4, thereby determining its working stability). When an abnormality is detected, the abnormal data is divided into the format of the fault source information category threshold by the main controller Ⅱ12 to select the target object level (according to Table 1, whether to select local or remote processing) to complete the transmission of the fault source data.

[0109] The main function of the intelligent road spike host is to receive data from the intelligent road spike slave and to communicate locally and remotely. The main functions of the intelligent road spike slave are: ① Send the fault data information of the intelligent road spike slave to the intelligent road spike host. ② Form a laser beam 19 with the laser transmitter of the intelligent road spike host to sense the target.
