Development of intelligent operation monitoring system for irrigation pump

For the purpose of improving the irrigation pump performance,reducing the energy consumption and ensuring the quality of irrigation water,an intelligent operation monitoring system for irrigation pump based on the single chip microcomputer STM32 F103 ZET6 was developed,which has the ability to acquire the irrigation pump performance parameters and irrigation water quality information in real time. The developed system mainly consisted of the MCU core control module,the water quality monitoring module,the voltage and current signal acquisition module,the GPRS communication module,the monitoring information display module and the power supply module. These functional modules were designed and accomplished both in hardware and software,and combined to multi operation and information display platform to realize the real time monitoring of irrigation pump. A prototype was manufactured and experiments were conducted to verify its reliability. The experimental results show that the system is worked normally and the monitoring information update frequency of the intelligent operation monitoring system is maintained at 2 000 Hz stably,and the monitoring error of each parameter is controlled within 0.5%.
