Application of Electricity Sensor in Electricity Measurement and Control System [Copy link]

A centralized power measurement and control system is designed. The system consists of a PC (host computer) and a power
acquisition system (slave computer) with 5 single-chip microcomputers as the core. The RS-485 interface of the host computer is connected to the RS-485 interface of each slave computer through a cable to form a
networked measurement and control system; the slave computer uses a new electronic power sensor AD7751 as a power measurement element to achieve multi-point power
detection and power theft detection. Because the system uses a special power sensor, the power calculation method is simple, and accidents such as system short circuit and power theft can be detected in time
, which helps to improve the safety of power use.
