Multifunctional electrical equipment power detection system based on EMI filter power supply

Abstract

The invention discloses a multifunctional electrical equipment power detection system based on an EMI filter power supply, including a voltage detection module, a current detection module, a data conditioning module, a processor module, a data transmission module, a commercial power access module, an EMI filter module, an AC / DC conversion device, a high-frequency transformer, and a data transmission module. The voltage detection module and the current detection module are connected with the processor module through the data conditioning module. The commercial power access module passes throughthe EMI filter module, the AC / DC conversion device and the high-frequency transformer in turn and is then connected with the processor module. The processor module is connected with the data transmission module. The readings of smart electric meters are gathered to a microcontroller module. Through data transmission via a wireless network, the efficiency and accuracy are improved, and human resources are greatly saved. Intelligent monitoring of power parameters is finished through voltage and current detection.

Description

technical field [0001] The invention belongs to the field of intelligent monitoring, and in particular relates to a multifunctional electrical equipment power detection system based on an EMI filter power supply. Background technique [0002] Smart meters in most cities in my country generally adopt the manual meter reading management method. The line-finding personnel carry portable detection equipment to each smart meter. When a fault occurs, the staff will be sent to repair it and then deal with it accordingly. This method has certain flexibility. Sex and sensitivity, but this traditional detection method has many loopholes in time and space. It cannot timely and effectively know the faulty electric meter. It needs to invest a lot of manpower and material resources, and the use effect is not good. [0003] Wireless network refers to the combination of various information sensing devices, such as radio frequency transmitters, positioning systems, laser scanners, etc., with ...
