Abstract: Aiming at the parts quality measurement process in the digital closedloop manufacturing, a wireless terminal for onmachine measurement system of parts quality was designed. Firstly, framework of the onmachine measurement system was given, and functional requirements of the wireless terminal were presented afterwards. Then, hardware module selection and design, software module and workflow of the wireless terminal were introduced, and the PC configuration software of WiFi network was designed. With a core embedded STM32 chip, the terminal was composed of RS485 communication module, WiFi and GRPS wireless network communication modules, etc. The terminal software was composed of the quality data collection, data format processing, wireless communications networks, field equipment control and GPIO interface module, etc. The results indicate that, as a critical component in the connection of field equipment and cloud server, this terminal can be used for the parts quality data acquisition, remote equipment monitoring, and parts quality control based on the cloud computing technology.
