[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0015] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0016] like Figure 1As shown, one embodiment of this utility model relates to a three-color traffic light control device based on carrier communication, including a control panel 10 and a control box 20. The control panel 10 integrates a main control module 11, as well as operation buttons 12, a dimming potentiometer 13, and indicator lights 14 electrically connected to the main control module 11. The control box 20 is equipped with a carrier communication module 21 and a communication module 22. The main control module 11, the carrier communication module 21, and the communication module 22 are connected via a CAN bus. The carrier communication module 21 controls multiple three-color traffic lights 30. In one example, the carrier communication module 21 modulates the carrier signal and transmits it to the three-color traffic lights 30 via power lines, thereby easily controlling the colors of the three-color traffic lights 30 to switch between white, red, and green. This effectively reduces the number of single-color traffic lights to be laid, reduces the amount of traffic light cables to be laid, and lowers the difficulty and cost of construction. The reduction in the number of traffic lights also simplifies the light mast structure. Using a power line carrier communication scheme, there is no need to lay additional signal lines, making installation easier and facilitating the upgrading of existing traffic light control devices.

[0017] like Figure 2 As shown, one embodiment relates to a three-color traffic light control device based on carrier communication.

The operation buttons 12 are connected to the input terminals of the I / O expansion chips after being divided by resistors and regulated by Zener diodes. The main MCU unit 112 obtains the status of each input via the I2C bus. In one example, the I / O expansion chip is model PCA9535PW,118. Taking one input as an example, the digital input is divided by a 1.5K resistor R2 and a 10K resistor R3, then grounded after passing through a Zener diode D1 and a debouncing filter capacitor C1. The input terminal of the I / O expansion chip is connected to the filter capacitor and then grounded. Other inputs are similar and will not be described in detail.

In one example, the LED driver chip is a TM1809. Taking one PWM output as an example, the input signal DIN of the LED driver chip is connected in series with a 75R resistor to receive the signal from the previous LED driver chip, and the output signal DOUT is connected in series with a 51R resistor to send the signal to the next LED driver chip, thus outputting a PWM signal to the indicator lights 14.

[0021] like Figure 6As shown, in one example, the carrier communication module 21 is an ES1670-C. The carrier modulation and receiving unit 214 is powered by the carrier power supply unit 213. The carrier power supply unit 213 provides a +24V power supply that is stepped down to a +12V power supply mode. The carrier modulation and receiving unit 214 communicates bidirectionally with the carrier MCU unit 212 via a serial port (RX / TX). The RX pin of the carrier modulation and receiving unit 214 is connected to the TX pin of the carrier MCU unit 212, and the TX pin of the carrier modulation and receiving unit 214 is connected to the RX pin of the carrier MCU unit 212.
