霍尔和磁阻技术在智能水泵控制器中的应用

Application of Hall and Magnetoresistance Technology in Intelligent Pump Controller

本文根据目前国内居民、工业、灌溉设施现状,中国的水资源分布以及使用现状,揭示了一种水流水压检测系统,包括逻辑控制器、电源变换电路、信号驱动器、霍尔水流感应传感器、磁阻水压感应传感器。本控制系统可以检测使用环境中是否有漏水、渗水、设定水压、稳定水压、检测水流,若系统水压不足或者有漏水的情况,报警信号灯会亮;若系统处于冲水状态,信号指示灯会亮。由于本系统可以设定水压、对漏水进行报警,可以达到节约用水的目的,从而辅助缓解目前中国的缺水状况。

According to the current situation of domestic residents, industry and irrigation facilities, water resources distribution and utilization in China, this paper reveals a water pressure detection system, including logic controller, power conversion circuit, signal driver, Hall water flow induction sensor, magnetoresistive water pressure induction sensor. This control system can detect whether there is leakage, seepage, set water pressure, stabilize water pressure and detect water flow in the use environment. If there is insufficient water pressure or leakage in the system, the alarm signal light will be on;if the system is in the flushing state, the signal indicator light will be on. Because the system can set the water pressure and alarm the leakage, it can save water and help alleviate the current water shortage in China.
