基于STM32的无线多源数据采集系统的设计

Design of Wireless Multi-source Data Acquisition System Based on STM32

针对传统的嵌入式数据采集系统的单一性输入、交互性差和传输距离有限的缺点,设计了一种以STM32H750XB为核心控制器的无线多源数据采集系统。系统支持以标准电信号形式的多源输入,通过自行设定与输入数据的变换关系,实时动态地将数据波形图显示到人机交互屏幕,并通过无线通信模块进行远程数据监控和系统控制。试验结果表明,系统能满足同时采集多路多源数据的采集要求,且测量精度高,无线通信传输稳定,可适用于家居、野外和农业等多种场合。

Aiming at the shortcomings of single input,poor interactivity and limited transmission distance of the traditional embedded data acquisition system,a wireless multi-source data acquisition system with STM32H750XB as the core controller was designed.The system supports multi-source input in the form of standard electrical signals.Through self-setting of the transformation relationship with the input data,the data waveform diagram was dynamically displayed on the human-computer interaction screen in real time,and the remote data monitoring and system control were carried out through the wireless communication module.The results show that the system can meet the requirements of multi-channel and multi-source data collection at the same time,with high measurement accuracy,stable wireless communication and transmission,and can be applied to many occasions such as home,field and agriculture.
