ShunNan Nature Gas Station Computer Monitoring System Study And Development

When the development scale of natural gas is larger and larger, gas transmission and distribution system is bigger and more complicated. It is not easy for people to master the running regulation of pipe-network, to monitor ,control, analysis and treatment the process condition of pipe-network,to measure the natural gas precisely. It is necessary to develop a new and advanced computer monitor system for nature gas station. The paper analysis the main problem of ShunNan nature gas station ,develop a distribute measure central query, manage and monitor system, realize the process condition automatic detection and remote monitoring, complete steady-state simulation and dynamic simulation of pipe-network, optimize the nature gas scheduling, enhance the gas usage efficiency.The paper based on the structure of ShunNan gas pipe-network, complete holistic design of computer hardware, collect site signal and data of evey measure point by ADS125 chip, design anti-jamming way during the measured-signal transmission process, setup interface parameters and design long-distance communication based on configuration soft MCGS, according to the rule of measure standard SY/T6143—1996, realize the on time measure, add up flux and historyparameters storage and management of nature gas.The paper complete holistic design of ShunNan nature gas station computer monitoring soft, according to international standard about savageness gene, based on configuration soft MCGS design script programmer for nature gas measure with volume flux arithmetic and compensate technology, develop soft about measure process with two computer hot standby, manage the database of measure monitoring system. It is easy to master the production, provide, sell running condition of nature gas, and it is easy to make decision and analysis.At last, the paper aim at the gas flux calculation problem in gas pipe-net, take advantage of numerical method's Jacobian matrix and method of characteristics, built the steady-state simulation and dynamic simulation model, realize the simulation by configuration soft MCGS, optimize the nature gas scheduling. It is more precise, reliable during the running of the monitoring system with stronger function.The monitoring system have been run, identified by technology supervise section of bureau, the measure precision of nature gas is more precise than the first class measure of nature standard, reliable , and satisfy the engineering need.
