Design of Remote Terminal of Air Compressor Based on STM32 and GPRS

摘要

In this paper,a remote terminal of air compressor based on STM32 and GPRS is designed,which is used to collect data of air compressor in real time and upload data to server end through GPRS network.The power and signal physical isolation hardware design,to ensure the safety of equipment and terminal isolation,software using the exception handling and heartbeat mechanism,improve the stability of the remote terminal connected to the server.The data transmission protocol to streamline the security to improve the real-time and reliability of GPRS network transmission.The operation results show that the air compressor remote terminal has strong anti-interference ability,and the automatic dropping of the line can be automatically reconnected,and the comprehensive packet loss rate is about 0.23%,and the expected results can be achieved.
