[Abstract]:With the rapid development of domestic natural gas industry, natural gas compressor units, as the key supercharging equipment in the natural gas production process, have been widely used. The natural gas compressor unit has the characteristics of large investment, complex structure and continuous operation all year round. In order to reduce the loss caused by the fault of the unit and improve the reliability of the unit, It is very important to equip a set of reliable operation monitoring system for the natural gas compressor unit. The operation monitoring system can monitor the operation parameters of every part of the unit in real time, and any abnormal parameters can alarm or stop in time. Can effectively avoid the occurrence of unit failures, reduce the labor intensity of operators, improve the level of equipment management. The importance of natural gas compressor unit and its monitoring system in petroleum and natural gas industry is first expounded, and the structure, principle, type and application characteristics of computer monitoring system in natural gas compressor unit are summarized. Based on the analysis of the composition and working principle of the integrated natural gas compressor unit and the requirements of the monitoring system for the engineering practice, the basic principles and general technical specifications for the design of the monitoring system for the natural gas compressor unit are clarified. Overall design scheme and design steps. The natural gas compressor unit monitoring system includes two parts: the lower computer monitoring system and the upper computer monitoring system. The hardware design and software design of the lower computer monitoring system are carried out. In the hardware design, the hardware selection is first completed, and then the electrical schematic design and field installation of the system are completed. The software design includes the design of PLC control program and touch-screen configuration program to realize the logic control and man-machine interaction function of local monitoring of natural gas compressor unit. Through the development of system communication setup and configuration software program, the remote monitoring of natural gas compressor unit by the upper computer system is realized, which meets the practical needs of the project.
