Intelligent Vacuum-pumping Detection Device Base On STM32MCU

摘要：

　　Large centrifugal water pumps are widely applied in various water-supply and drainage systems.The vacuum-pumping is pre-requisite for their start-up so that the intelligent vacuum-pumping detection device utilizing STM32F103 as the main controller was presented to realize the automatic control especially of unattended pumps.A differential pressure transducer was adopted to measure the vacuum degree in pump chamber.Afterwards, an electrical signal of corresponding value was output, and then entered the ADC of STM32F103 after conditioning.The threshold algorithm was introduced for the judgement whether vacuum-pumping had been accomplished.Actual applications indicated this detection device was feasible and reliable, and the judgement algorithm was simply implemented and performed well in practice.
