With the development of electrical engineering, the performance requirements of existing feeder automation terminal devices for protection devices are increasing. This project uses STM32F103ZET6 as the main control MCU, with 4.3' TFTLCD LCD touch capacitive screen as the display and control device, and RN8302 chip with mutual inductor to form the acquisition circuit. The acquisition chip can use current and voltage transformers to directly calculate the parameters of the feeder automation terminal device, and then transmit the data to the main controller, and then analyze the status and information transmission of the collected parameters, and display the final results on the display, and can be synchronously transmitted to the cell phone.
