Design of network multi point remote data monitoring system based on STM32 and SIM900A

针对工业上监测现场数据采集的远程网络传输需求,提出了一种基于STM32F103微控制器和SIM900A通信模块的网络多点远程数据监测系统。STM32下位机可以完成各传感器的周期性数据采集,并利用SIM900A模块实现其与远程上位机在GPRS网络上的不依赖监测现场网络环境的TCP数据通信。系统可以实现不间断对多个监测点的多个监测对象同时进行数据采集和远程数据传输。现场实验表明,该监测系统稳定性高、实时性强、测量误差小、功耗低,可以满足工业上的设计要求。

According to the demand of remote network transmission monitoring field data acquisition in the industry, this paper proposed a net- work multi point remote data monitoring system based on STM32F103 microcontroller and SIM900A communication module. STM32 MCU can complete periodic data acquisition of each sensor and use SIM9OOA module to realize the data communication with the remote host TCP in the GPRS network, which does not rely on monitoring network. The system can carry out data collection and remote data transmission to multiple monitoring points at the same time without interruption. The field experiment shows that the monitoring system has high stablity, strong real- time performance, small measurement error, and low power consumption, which can meet the design requirements of the industry.
