With the development of industrial gas supply and user requirements for continuous improvement to ensure the supply pipe network security, stability, economic operation, improve the gas efficiency of management, modern management to achieve the level of the gas network, gas pipeline network with computer monitoring system for gas centralized network management to monitor and quantify is the city's current development trends.
First, the system structure
City gas pipeline network monitoring and dispatching emergency standby master and door stations from the master station is responsible for the reserves stood regulator stations, valve stations and pressure measurement points, measurement points of the automation equipment, instrumentation and the corresponding parameters, real-time monitoring of the pipe network heating of the whole process, clearly reflect the real-time operation of the site; detailed record of the pipeline operating parameters of the site; centralized display temperature, pressure, flow rate, cumulative flow, and other parameters. Distributed in many sites around the city with the master to maintain real-time reliable data transmission, digital radio because of its high performance, reliability and low operation and maintenance costs to be more and more applications.
Multipoint wireless data acquisition monitoring system
Measurement points of the valve stations and unattended remote control determines the radio tower to be installed outdoors, requires radio stations to withstand harsh weather conditions; the large systems, monitoring of the valve stations and the number of measurement points than to require wireless higher rate communication system, polling response time faster; the same time as the gas industry for the country's energy infrastructure, which is equipped with industrial control systems are the most advanced and reliable equipment, so the key to the whole system to ensure that the wireless communication link must be reliable stable and high performance industrial control systems to ensure the best operation.
Second, the specific application
Tianjin gas pipeline, gas pipeline, Wuhan, Lanzhou, gas, etc.
