CNG加气站卡机联动及网络管理系统的分析与应用

随着CNG技术的广泛应用，天然气汽车数量的不断增加，CNG站将逐步使用卡机联动及网络管理系统，全面实现自动化管理，提高工作效率。针对大港油田CNG站2005年引进卡机联动及网络管理系统，我们对卡机联动、通讯功能及定额、定量加气功能等方面进行了分析、改进，使该系统在应用上更加快捷、高效、准确。文中从卡机联动系统功能，卡机联动改造分析与研究以及系统的优势等方面进行了较详细的阐述。

ANALYSIS AND APPLICATIONS OF CNG GAS STATION UNITED CONTROLLING SYSTEM WITH CARD AND MACHINE AS WELL AS THE NETWORK AUTOMATIC MANAGEMENT

With the worldwide application of CNG technology,the quantity of automobiles fueled by natural gas increase very fast.In order to achieve the comprehensive automatic management and to enhance the working efficiency,CNG station is going to utilize the united controlling system with card and machine and the network automatic management system.On the basis of the united controlling system with card and machine and the network automatic management system that Dagang Oilfield introduced in the year of 2005,we analyzed and improved the united controlling system with card and machine,communication function and the gas filling with fixed quantity and quota function in order to make the system even more efficient,more effective and more accurate in the application.The function of this system it ortroduced in the paper,the system reconstruction and its advantages are expounded in detail.
