In view of the characteristics of wireless communication and the functional requirements of a certain type of wireless communication system, a control terminal based on STM32 microcontroller is designed. This paper designs a terminal by adopting the modular design method to optimize the manmachine interface of the communication system and by utilizing the rich peripheral devices and the powerful data processing ability of STM32. The terminal has a friendly manmachine interaction mode, and provides a large number of data ports for the communication system, realizing the logical coordination between the modules. Through the experiment, the manmachine interaction, state monitoring and short message sending and receiving functions of the terminal are tested. The test results show that the operating interface of the system is simple and efficient, and the management of the working state monitoring, communication parameter setting, radio frequency data reading and control operation of the wireless communication system is realized. The terminal can detect the running state of the system in real time, and the short message data of the terminal is sent and received normally, and the six communication records can be displayed simultaneously on the control interface. Compared with the same kind of design, this terminal has some improvement and has great practical value for miltary.
