"智能潜水泵保护器设计研究——基于单片机控制技术应用"

The research paper "Design and Research of Intelligent Submersible Pump Protection Device Based on Single Chip Microcomputer" highlights the widespread application of submersible pumps in agriculture and the frequent occurrence of motor burnout accidents due to harsh working conditions underwater, particularly caused by the lack of water in the pump. To address this common issue, the paper introduces a controller designed for monitoring and protecting submersible pumps. Two protection modes are discussed in the paper: the first is a water level control mode where the pump automatically starts when the water level in the tank is below a certain point and stops when it reaches a certain level. If the pump runs dry during operation, it will automatically shut down and restart after a user-defined delay period, which can be adjusted according to the water source conditions. The second mode is a timed pumping mode where the system can automatically start and stop the pump based on pre-set intervals and durations, effectively preventing pump burnout due to water shortage. The paper outlines the overall design concept of the intelligent submersible pump protection controller and provides detailed hardware circuit diagrams and software flowcharts. The key components of the design include the single-chip microcomputer AT89C51, submersible pump, and the protection controller. Overall, the research paper presents an innovative solution to the common problem of submersible pump failure due to water shortage, offering a practical and efficient method for monitoring, protecting, and optimizing the performance of submersible pumps in agricultural applications.
