The passive wireless electrical monitoring system, based on the new generation of Internet of things, self powered, ultra-low power consumption, mixed networking and other technologies, can continuously measure the equipment current, voltage or line temperature, obtain the working condition, operation and safety data of electrical lines and electrical equipment in real time, and analyze the startup, shutdown, standby, operation, idling and other states of the monitored equipment in combination with the platform big data AI diagnosis function, Realize the fine operation management of leased equipment. At the same time, alarm the abnormal behaviors such as low operating rate, equipment movement, low battery capacity, acquisition interruption or offline, equipment removal and so on, timely remind and check, reduce the leasing risk, and realize the purposes of asset monitoring, abnormal early warning and risk control.

The system can be applied to equipment leasing, intelligent manufacturing, environmental protection supervision, charging pile management, commercial super cold storage, hotel office and other industries. It can effectively realize the connection of equipment and things, and solve the problems existing in traditional sensors, such as power supply, cumbersome installation, high cost and data transmission, so as to achieve the purpose of self correction, self inspection and effective supervision of abnormal working conditions, so as to make production management and maintenance more smart.
