Centrifugal pump motor condition monitoring devices based on android platform

The utility model discloses a centrifugal pump motor condition monitoring devices based on android platform, include centrifugal pump motor electric current, voltage signal collection module based on the ATT7022B chip, based on the receipt of STM32 microcontroller data, analysis processes module, data communication and sharing module, android customer end and the host computer under the labwindows environment. Through based on centrifugal pump motor electric current, the voltage signal collection module of ATT7022B chip, collect motor stator current signal, voltage signal turn into current signal, voltage signal the rotational speed and the power signal of centrifugal pump again, utilize the power sum rotational speed signal that obtains then, combine the characteristic curve and the proportionality law of pump, the performance of the pump that converts out, for example lift, efficiency equivalent go to judge corresponding operating mode, and pass through data communication with information and sharing module
