Natural gas pressure regulating station remote monitoring system based on sensor network

Abstract

The invention discloses a natural gas pressure regulating station remote monitoring system based on a sensor network. The natural gas pressure regulating station remote monitoring system is characterized by comprising a monitoring center, a convergence node and a sensor network formed by a plurality of sensor nodes for data acquisition; wherein the sensor nodes perform information exchange with the monitoring center via the convergence node; each of the sensor nodes includes a microcontroller module, a field electrical device, an optical coupler isolation module, a data transmission module, apower module and a data storage module; the power module includes commercial power, an EMI filter module, a circuit switching module and a standby battery module. In order to prevent accidental interruption of an external power supply, the standby battery module is designed. When an external circuit operates normally, the battery does not supply power. When the external power supply is interrupted, the battery supplies power to the system immediately in order to guarantee the normal operation of the system.

Description

technical field [0001] The invention belongs to the field of intelligent monitoring, and in particular relates to a remote monitoring system for a natural gas pressure regulating station based on a sensor network. 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 pro...
