Abstract
In order to realize the function of an automatic target-scoring system for shock wave pressure signal positioning, it is necessary to collect multi-channel shock wave pressure signals. Therefore, this paper designs a sensor signal acquisition and processing system based on STM32. The system can realize the acquisition and processing of 8-channel sensor signals. The hardware module includes the operational amplifier module, the acquisition conversion module, the temperature acquisition module, and the wireless transmission module. In order to solve the positioning coordinates, the program is written based on Keil uVision5 and STM32 firmware library. The PYQT5 is called to design the host computer receiving software. Finally, the acquisition test of the designed acquisition system is carried out. The test results show that the signal reduction degree of the designed acquisition system is more than 90%. The designed signal acquisition system has the advantages of high reliability and small size. It also has a certain universality.
