In the absence of traffic signal 01 or platform 02, the light color conversion of tidal variable lane indicator light 03 can also be controlled according to the internal preset scheme; control module 00 also processes the light color information sampled by fault detection module 40 in real time to determine whether the tidal variable lane indicator light 03 is normal, performs corresponding fault processing according to different fault states, and also sends the tidal lane fault information to other control intersections of this tidal lane through 5G. The tidal variable lane controllers at other intersections will perform corresponding fault processing upon receiving the fault information; at the same time, control module 00 will also send the light color and fault state of tidal variable lane indicator light 03 to platform 02 through a wired or wireless network. Control module 00 has a processor, preferably, the chip model of the processor is FET3568.

[0024] Light control module 10: The input end of the light control module 10 is connected to the control module 00, and the output end of the light control module 10 is connected to the tidal variable lane indicator light 03.

When the light control module is in a fault state, the backup light control module 20 can control the passing and prohibiting light color information of the tidal variable lane indicator light 03 in real time through the control of the control module 00.

[0026] Mains switching module 30: The mains switching module 30 is connected to the lighting control module 10 and the backup lighting control module 20 respectively to switch the power of the lighting control module 10 and the backup lighting control module 20. Specifically, when the lighting control module 10 is working, the mains input is provided to the module, and the mains switching module 30 cuts off the power of the backup lighting control module 20; when the backup lighting control module 20 is working, the mains input is provided to the module, and the mains switching module 30 cuts off the power supply of the lighting control module 10.

[0027] Fault detection module 40: The input end of the fault detection module 40 is connected to the tidal variable lane indicator light 03 to detect and compare the voltage and current of the tidal variable lane indicator light 03, and the output end of the fault detection module 40 is connected to the control module 00. Specifically, the fault detection module 40 can detect the voltage and current of the tidal variable lane indicator light 03 in real time, and compare the real-time detected voltage and current with the pre-stored normal current and voltage values ​​to determine whether the tidal variable lane indicator light 03 is in a fault state.

[0028] Communication module 50: The input end of the communication module 50 is interactively connected with the traffic signal 01, and the output end of the communication module 50 is connected with the control module 00.

The network module 60 mainly converts the RMII interface of the control module 00 into a standard RJ45 interface to facilitate communication with the platform 02 and other network interfaces.

[0030] GPS module 70: GPS module 70 is interactively connected with control module 00 for time calibration and positioning of the controller. Time calibration makes the time of the tidal variable lane controller more accurate; positioning can know the location where the tidal variable lane controller is installed, so that when a fault occurs, the faulty device can be accurately found for repair or replacement.

[0031] Status indication module 80: The status indication module 80 is connected to the output end of the control module 00. The status indication module 80 has an LED light and an OLED screen to display the status of the controller in real time.

[0032] The working principle of the utility model is: Figure 3After the tidal variable lane controller is powered on, it will actively connect to platform 02 through the wired network RJ45 or 5G wireless module and send a request control instruction to the traffic signal 01. If the traffic signal 01 or platform 02 returns the control instruction, the tidal variable lane controller controls the light color of the tidal variable lane indicator light 03 according to the command issued by the traffic signal 01 or platform 02; if the traffic signal 01 and platform 02 do not issue a control instruction, the tidal variable lane controller controls the light color of the tidal variable lane indicator light 03 according to its preset plan; when platform 02 and traffic signal 01 issue control instructions at the same time, the tidal variable lane controller determines the execution instruction according to the priority of the instructions of the traffic signal 01 and platform 02, that is, executes the control instruction with high priority.

[0033] After executing the control of the light color, the tidal variable lane controller will detect the voltage and current of the tidal indicator light or the variable lane indicator light in real time. When the voltage and current of the indicator light are not within the preset normal value range, the indicator light fault will be reported. Among them, the tidal indicator light fault is divided into lamp damage, lamp error, prohibition and passage lights are lit at the same time, and the opposite tidal passage lights are lit at the same time; the lane indicator light fault is divided into lamp damage, lamp error, variable lane lights are lit at the same time, etc.

[0034] After detecting a fault, the tidal variable lane controller will immediately turn off the power supply of the light control module 10, turn on the power supply of the backup light control module 20, and use the backup light control module 20 for control. Under the control of the backup control module 20, if the fault is eliminated, it is determined that the light control module 10 is faulty; if connected to platform 02, the fault information will be reported to platform 02; if connected to traffic signal 01, the fault information will be reported to traffic signal 01; at the same time, the fault message will be sent to relevant maintenance personnel through the 5G module. If the fault is not eliminated after switching to the backup light control module 20, if connected to platform 02, the fault information will be reported to platform 02; if connected to traffic signal 01, the fault information will be reported to traffic signal 01, and at the same time, the fault message will be sent to relevant maintenance personnel through the 5G module, and they will be processed according to the corresponding fault. Specifically, if the no-traffic light of the tidal lane is damaged or the no-traffic light of the tidal lane is mistakenly lit, the traffic light in the opposite direction of the faulty tidal lane signal light will be turned off, the no-traffic light of the tidal lane will be turned on, and the tidal variable lane controllers of other intersections of the tidal lane will be sent through the 5G module to switch the two-way tidal lane indicator lights to no-traffic control; if the no-traffic light of the tidal lane is damaged or the no-traffic light of the tidal lane is mistakenly lit, the fault will be reported and not processed temporarily while waiting for maintenance; if the opposite tidal traffic lights are on at the same time, the traffic lights will be turned off first, the no-traffic lights will be turned on, and the 5G module will be sent to other intersections of the tidal lane to switch both directions to no-traffic control; if the fault is still there, the power will be turned off and the relevant maintenance personnel will be notified urgently for maintenance; if the variable lane control light is damaged, the fault will be reported and not processed temporarily while waiting for maintenance; if the variable lane control lights are on at the same time, the power supply of the lighting control module 10 will be turned off, and it will be reported to the relevant personnel for maintenance. After the fault is resolved, the tidal variable lane controller will send fault clearance information to other intersections of the tidal lane through the 5G module, allowing other intersections to return to normal tidal lane control.
