Design of Electrical Equipment Monitoring Device Based on STM32F411

The working current is an important indicator to measure the operating status of electrical equipment. Continuous monitoring of equipment status is crucial for maintaining its normal operation. A device for monitoring electrical equipment current was designed, with the goal of achieving precise and continuous monitoring of equipment operation. The device uses sampling resistors and the HLW8032 chip to precisely acquire current data from electrical equipment, and the STM32F4 11 microprocessor (intelligent processing module) calculates and processes the equipment data characteristics. The processed data is transmitted to the server via the WIFI data exchange module, and the Web server displays the real-time monitoring data of equipment operation. When the equipment operation data is abnormal, the data received is stored in the database server, and an alarm is issued and a warning prompt is given to the alarm module, achieving real-time monitoring of equipment operation data. The experimental results show that the device can reliably and accurately acquire current data and monitor equipment status in real-time.
