GPRS-based wireless remote online monitoring system of distributed arrester

Abstract

The invention discloses a GPRS-based wireless remote online monitoring system of a distributed arrester, comprising a distributed field detection terminal, field detection terminals, a mobile base station, Internet, a router, a monitoring computer and monitoring client computers. The mobile base station, the Internet and the router are all public information infrastructures. The distributed fielddetection terminal is used for completing real-time online detection of the operating parameters of the arrester and realizing wireless remote transmission of the operating parameters to the mobile base station via a wireless access module. The monitoring computer is used for remote monitoring of the field operating condition of the arrester and remote control of the working mode, relevant information management and user management of the detection terminal. The system is the remote, non-contact, networked and real-time online monitoring system, and the monitoring is accurate, real-time, convenient and strong in practicality.

Description

technical field [0001] The invention relates to a wireless remote on-line monitoring system of a collection and distribution lightning arrester, which realizes the collection of information such as the total leakage current of a lightning arrester (MOA), the phase angle between the total leakage current and voltage, and the number of times the lightning arrester is struck by lightning. Background technique [0002] Since the 1970s, various countries have conducted in-depth research on zinc oxide arresters (MOA) and their detection methods. At present, most zinc oxide arresters at home and abroad are without gaps. Due to the long-term operating voltage and various external factors during operation, the deterioration of the zinc oxide valve plate is accelerated, so its performance needs to be checked regularly. Initially, the detection method of the arrester was manually detected when the power was off. With the emergence of new technologies and the deepening of the research o...

Problems solved by technology

The use of fieldbus technology has the characteristics of simple protocol, strong fault tolerance, good security, long transmission distance, and strong anti-interference ability. However, due to the scattered layout of arresters, if the bus is used for monitoring, it is necessary to lay cables or optical cables. Very inconvenient, too costly, and not very scalable
