【Abstract】 The low-cost and intelligent measurement of agricultural irrigation water has always been a problem to be solved in the industry. An electric-water conversion measurement method is proposed for pumping stations,and a fully intelligent measurement system for agricultural irrigation water based on NB-IoT is designed.The important components of the system include: NB-IoT-based sensing and metering pre-terminal,improved particle swarm optimization-based electricity-water conversion algorithm, B/S-based background management system and mobile phone APP system. The system uses embedded technology,Internet of Things communication technology and electricity-water conversion algorithm. Compared with the existing intelligent monitoring and measurement system based on flow sensors,the system has a higher cost performance ratio and has been widely applied.更多还原
