Energy efficiency and safety integrated monitoring method and device for ventilator or water pump

The invention relates to the technology of ventilators or water pumps, and aims to provide an energy efficiency and safety integrated monitoring method and device for a ventilator or a water pump. A data processing module, a signal input and output module, a data storage module, a display module, a communication module and a power supply module are arranged in a hollow shell of the device; and the data processing module is connected to each module through a signal line, and the power supply module is used for supplying power to each component. Operation energy efficiency analysis, vibration spectrum analysis and control functions are integrated, and the method can be widely applied to various ventilators or water pump equipment and has very high applicability. A local data storage function is achieved, and historical data comparison can be achieved without networking. Parameters of an inlet pipeline and an outlet pipeline of a ventilator or a water pump can be sampled in real time, online energy efficiency ca
