Remote monitoring system for natural gas pressure regulating stations based on MOBUS protocol

Abstract

The invention discloses a remote monitoring system for natural gas pressure regulating stations based on a MOBUS protocol. The remote monitoring system includes a monitoring terminal and a plurality of data acquisition terminals connected with the same via a remote transmitting module. Each data acquisition terminal includes a salve computer and a field electrical device connected with the same. The data acquisition terminal further comprises an optical coupler isolation module. The field electrical device is connected to the slave computer through the optical coupler isolation module. The remote monitoring system is designed for problems that natural gas pressure regulating stations are spaced far away from one another and high in dispersity and a traditional wired monitoring system cannot be completely competent in the monitoring of the pressure regulating stations. The natural gas remote monitoring system is formed by the remote data transmission module in combination with a STM32and the MODBUS protocol so as to achieve the wireless remote monitoring of natural gas and meet the monitoring needs of a wide range and long distance.

Description

technical field [0001] The invention belongs to the field of intelligent monitoring, in particular to a remote monitoring system for a natural gas pressure regulating station based on the MOBUS protocol. Background technique [0002] The coverage of natural gas transmission is very wide. In the transmission of natural gas, the natural gas pressure regulating stations that provide the transmission pressure and control the flow of natural gas are distributed in various regions. The traditional monitoring system of natural gas pressure regulating station adopts manual control, which cannot realize automatic, remote and centralized operation of data monitoring. In particular, the data transmission has always been on-site wiring, which cannot realize long-distance real-time monitoring. In the context of today's greatly increased natural gas consumption, the development of a reliable and practical natural gas remote automatic monitoring system can greatly improve the production an...
