摘　　要：农业墒情站能够对农作物生长环境进行全方位的检测,为农业生产和农业环境调节提供科技保障,但农业墒情站采用太阳能系统进行供电,由于太阳能系统受天气影响较大,连续阴天会使得设备因供电不足而无法正常工作,因此研究农业墒情站功耗问题极为重要。文中提出了一款基于农业墒情站的多路功耗采集系统,主要由五部分组成:以STM32F103ZET6为核心的数据处理模块、电流电压检测模块、GPRS传输模块、光照传感器模块以及供电模块。系统通过STM32F103ZET6芯片对墒情站各模块的功耗数据(电流电压检测模块所检测到的电流电压数据)及光照强度数据进行采集,按照自定义的通信协议将数据进行帧封装,由GPRS模块上传至PC端进行显示。系统测试结果表明,该系统运行稳定,可以实时测量墒情站的功耗数据,为后续功耗优化实验提供基础。Agricultural soil moisture station can carry on the full range of testing environment for the growth of crops,and provide scientific and technological guarantee for agricultural production and agricultural environment regulation. It is crucial to study the power consumption of the soil moisture station because the solar system,which is used to supply power to the soil moisture station,is greatly affected by the weather,and the continuous cloudy days will make the equipment unable to work properly due to the lack of power supply. We propose a multi-channel power acquisition system based on agricultural moisture content stations,which is mainly composed of five parts:data processing module with STM32 F103 ZET6 as the core,current and voltage detection module,GPRS transmission module,lighting sensor module and power supply module. The system collects the power consumption data(current and voltage data detected by the current and voltage detection module) and illumination intensity data of various modules of moisture content station through the STM32 F103 ZET6 chip. The data are packaged in frame according to the custom communication protocol and uploaded by GPRS module to the PC terminal for display. The system test results show that the system is stable and can measure the power consumption data of moisture content stations in real time,which provides a basis for subsequent power optimization experiments.
