Research and Design of Intelligent Traffic Signal Light Handheld Control Terminal Based on STM32

In recent years, the number of motor vehicles in various countries has increased dramatically, as has the traffic signal system. Remote signal lamp system monitoring is the mainstream monitoring method at present, but remote control also has some disadvantages, so it is very important to study a signal lamp control terminal based on the scene. This paper studies the implementation and design of the real-time traffic signal handheld control terminal based on STM32. In the hardware part, the handheld control terminal core uses STM32F103RCT6. The main control board is integrated with a 2.8-inch TFT touch screen to facilitate the user to input control commands and display the response data of the controller. The control command is sent to the traffic signal controller in real time through the Si4463 radio frequency module. In the software part, the man-machine interface and wireless communication code of the control terminal are designed. When the sending button is pressed, the radio frequency module will be called and the control command will be sent to the controller according to the communication protocol of the controller. Meanwhile, the radio frequency module will wait for the response of the receiving controller. After receiving the response, the data will be displayed on the touch screen for the user to read. The debugging results show that the control terminal is cost-effective, practical and can be used in various weather conditions and environments.
