Centrifugal pump motor state monitoring device and method based on Android platform

Abstract

The invention discloses a centrifugal pump motor state monitoring device and method based on an Android platform. The device comprises a centrifugal pump motor current and voltage signal collection module based on an ATT7022B chip, a microcontroller data receiving and analyzing processing module based on STM32, a data communication and sharing module, an Android client and an upper computer in Labwindows environment. The method includes: collecting motor stator current signals and voltage signals through the centrifugal pump motor current and voltage signal collection module based on the ATT7022B chip; converting the current signals and the voltage signals into rotating speed and power signals of a centrifugal pump; utilizing acquired power and rotating speed signals, and combining with characteristic curve and proportion law of the pump for conversion to acquire performances like lift and efficiency equivalence of the pump so as to judge corresponding working conditions; transmitting information to the Android client and the upper computer through the data communication and sharing module so as to remote monitor state of the centrifugal pump in real time. By the centrifugal pump motor state monitoring device and method, state predicting and monitoring of the centrifugal pump are realized by only utilizing electrical parameters of a driving motor.

Description

technical field [0001] The invention belongs to the technical field of data acquisition, in particular to a centrifugal pump motor state monitoring device and monitoring method based on an Android platform. Background technique [0002] Regarding the parameter detection of water pumps, the relevant research in developed countries such as foreign countries, Europe and the United States generally started earlier, and it is still ahead of China in some fields such as the manufacture of special pumps and the internal characteristic testing of pumps. As far as the external characteristic test device of the pump is concerned, as early as 1961, the British National Engineering Laboratory (NEL) established its own hydraulic machinery test bench, which can be used for performance tests of water pumps and model turbines (maximum runner diameter 0.5m) , Efficiency and cavitation tests can be carried out in open and closed cycle modes. Some parameters can be controlled semi-automaticall...
