基于STM32的励磁装置数据采集系统

励磁装置数据采集对于系统实时监视有重要意义。为了分析实时数据,实现励磁装置故障诊断和定位以及故障预测,基于STM32最小系统,设计了励磁电压、电流和发电机机端电压、电流信号调理电路,完成了高压、大电流信号缩放、平移和偏置等环节。综合分析STM32F407ZGT6资源,采用ADC双重同步触发模式和DMA数据转移,编写了相应数据采集程序,完成了多通道数据采集。通过CAN通讯将数据传输到上位机,上位机接收数据后由LabVIEW实时显示数据波形。

Data Acquisition System of Excitation Device Based on STM32

Data acquisition of excitation device is very important for real-time monitoring of the system.In order to analyze real-time data,realize the fault diagnosis and location and fault prediction of excitation device,the excitation voltage,current,generator terminal voltage and current signal conditioning circuit were designed,and the high voltage and large current signal scaling,translation and offset were completed based on STM32 minimum system.The STM32F407ZGT6 resources were comprehensively analyzed,and the corresponding data acquisition program was compiled by using ADC dual synchronization trigger mode and DMA data transfer,and the multichannel data acquisition was completed.The data is transmitted to the upper computer through CAN communication,after receiving the data,the data waveform is displayed by LabVIEWin real time.
