Multifunctional electric power monitoring system based on MODBUS protocol

Abstract

The invention discloses a multifunctional electric power monitoring system based on an MODBUS protocol. The monitoring system comprises a data monitoring terminal and multiple data acquisition terminals connected thereto through the MODBUS protocol. Each data acquisition terminal comprises a micro-controller module, a voltage detection module, a current detection module, an analog-to-digital conversion module, an amplifying circuit module, an RS485 port module, a positioning module, a display module, a wireless communication module, a memory module, a power supply manager and a power supply module. The monitoring system is characterized in that the monitoring device is low in cost and easy to achieve; the monitoring device is connected with multiple intelligent ammeters through the RS485 port modules; the reading of the intelligent ammeters are gathered to the micro-controller modules; through the data transmission of the wireless network, efficiency and accuracy are effectively improved; human resources are greatly saved; and through detection of the voltage and the current, intelligent monitoring of electric power parameters is finished.

Description

technical field [0001] The invention belongs to the field of intelligent monitoring, in particular to a multifunctional power monitoring system based on MODBUS protocol. 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 the Internet to form a huge network. Then,...
