[0037] In the wiring unit 11, the wiring unit is connected to the traffic signal cabinet; wherein the traffic signal cabinet includes traffic signal lamps with a countdown timer.

[0038] Spring terminal blocks are used on the detection device, thus facilitating the quick connection of the output wires and signal lamp wires of the controller in the traffic signal cabinet to the detection device.

[0039] The wiring unit 11 includes several voltage mutual inductance coils 21, several current mutual inductance coils 22 and several power chips 23. The models of the voltage mutual inductance coils 21, the current mutual inductance coils 22 and the power chips 23 are all Belling BL0937.

[0040] In this embodiment, the numbers of the voltage mutual inductance coils 21, the current mutual inductance coils 22 and the power chips 23 are the same, and also correspond to the number of traffic lights, so that one end of one voltage mutual inductance coil 21 and one current mutual inductance coil 22 are both connected to one traffic light, and the other ends of one voltage mutual inductance coil 21 and one current mutual inductance coil 22 are both connected to one power chip 23. Furthermore, the voltage and active power of the traffic lights are detected through the voltage mutual inductance coils 21, the current mutual inductance coils 22 and the power chips 23, and it can also adapt to various 220V signal lights of different styles. Moreover, even if the traffic light detection device is powered off or damaged, it will not affect the normal operation of the original signal light system.

[0041] In the data acquisition unit 12, the voltage and power data of the traffic lights are acquired.

[0042] The model of the data acquisition unit 12 is the Gowin GW2A FPGA chip, which can sample up to 48 signal lights; the FPGA samples once every 0.25 seconds and can analyze the power change of the signal lights within each second. From the data, it can analyze the flashing of the signal lights and the change of the countdown timer, and then acquire the voltage and power data of each traffic light in real time and quickly.

[0043] In the analysis and processing unit 13, the acquired data is analyzed to obtain the on / off states and fault types of each traffic light and countdown timer.

[0044] The model of the analysis and processing unit 13 is the Allwinner T113-i chip. It reads the acquisition data of each signal light through the SPI interface for analysis and calculation, and can judge the on / off states and fault types of the signal lights and countdown timers, providing fault analysis for the maintenance unit.

[0045] It should be noted that the analysis and calculation of the acquired data are realized by the Allwinner T113-i chip itself. In this embodiment, it is not necessary to improve this chip to obtain the on / off states and fault types of the signal lights and countdown timers.

[0046] In the positioning unit 14, the detection device is positioned.

[0050] In the power supply unit 16, electric energy is provided for the detection device.

[0051] The power supply unit 16 is a UPS power supply module 27. In the case of a power outage of the commercial power, the UPS power supply module can quickly switch to battery UPS power supply, and the power outage information can be transmitted to the network management platform and the mobile phone APP through the communication unit 15.

[0052] The auxiliary service unit 17 detects the traffic signal cabinet.

[0053] The auxiliary service unit includes auxiliary functions such as an RS485 interface 28, a cabinet door detection module 29, a water immersion detection module 30, temperature and humidity 31, an alarm 32 detection, etc., and can understand the internal operating environment of the traffic signal cabinet in real time, such as the cabinet door status, the internal environment of the cabinet, etc.

[0056] 2. After the first installation is completed, check the wiring to ensure normal operation and ensure that the signal lamp and the signal controller are normal; click the learning button, and the device will learn the information of the connected lamps, including whether there are lamps, countdown timers, and power values in various states.

[0058] 4. The detection device collects the voltage and power data of the signal lights in real time through the GaoYun GW2A FPGA chip, and at the same time compares with the data during learning through the Allwinner T113-i chip to determine whether the signal light or the countdown timer is damaged and whether there is voltage input; it judges whether there are disorders, conflicts, and simultaneous illuminations according to the phase relationship and the signal light change rules, and issues corresponding warnings.
