Remote monitoring maintenance method and system based on 3G and wind-solar complementary power supply technology

Abstract

The invention discloses a remote monitoring maintenance method and a remote monitoring maintenance system based on 3G and wind-solar complementary power supply technology. The method comprises programmable logic controller (PLC) data acquisition and control, wind-solar complementary power supply, 3G wireless communication and remote monitoring maintenance, wherein wind-solar complementary new energy power supply technology, 3G network communication technology and automation control technology are organically combined to acquire data of temperature, pressure, flow, water level, water quality and other data of a pump station and monitor the pump station on site. The remote monitoring maintenance system and the PLC data acquisition and control system adopt a distributed structure; the remotemonitoring maintenance system monitors the data of each PLC data acquisition and control system on line in real time; a 3G wireless communication system provides smooth and rapid communication for the remote monitoring maintenance system and the PLC data acquisition and control system; and a wind-solar complementary power supply system provides power supply for the PLC data acquisition and control system. The method and the system realize wireless energy of the remote pump station and data transmission operation.

Description

technical field [0001] The technical field of the present invention is the industrial automation industry, using 3G network to remotely monitor and maintain unattended pumping stations, and specifically relates to a method and system for remote monitoring and maintenance based on 3G and wind-solar complementary power supply technology. Background technique [0002] The pumping station is the main facility of the water conservancy project, and the pumping station facility plays a key role in urban flood control and drainage and rural water diversion and irrigation. With the rapid development of my country's economic construction, higher requirements are put forward for water conservancy facilities and water environment. Urban flood control and drainage, urban water environment, deep-water wells and drainage facilities all face the requirement of using modern information technology to further improve facilities. [0003] The realization of projects such as drainage, well gr...

AI Technical Summary

Problems solved by technology

Using the perfect combination of 3G wireless communication technology, network technology and industrial automation technology, it effectively solves the problem of laying special cables or GPRS wireless communication for video transmission and control of the controller program level (remote program upload and download, online diagnosis, etc.) , Pumping station maintenance personnel shortage, low quality, etc.

The application of new energy technology will effectively solve the problem of backup power supply for the communication system, and gain more time for maintenance operations after the pumping station equipment fails
