Detection and identification device of electric appliance

Abstract:
This design takes the high-precision electric energy metering IC ade7953 as the core acquisition, uses the stm32c8t6 single chip microcomputer as the control center for circuit control and data processing, measures the electrical characteristic parameters of electrical appliances and matches the internal storage parameters, and uses the Euclidean algorithm for parameter comparison to realize the identification of the types of electrical appliances, The final identification and analysis results are sent to LCD12864 display screen and app for real-time display. After testing, the system maintains a current of 10mA under the operation of USB adapter. After learning, it can identify different combinations of seven electrical appliances, meet the identification of random increase and decrease, and the response time is less than 2S, achieve the topic foundation and give full play to all indicators, and complete the real-time display of app.
