天然气脱水装置控制系统的研制

DEVELOPMENT OF COMPUTERIZED CONTROL SYSTEM OF INSTALLATIONS OF GAS PROCESSING

论述了替代进口控制系统的大庆天然气脱水装置控制系统的设计目标、设计思想、设计方案和实现技术，该设计采用了作者提出的实时系统的数据流／时间分析与设计方法，克服了原有系统的死机现象和切换跳闸现象．我们选择台湾研华计算机控制系统Ｃ选择Ｃ语言作为宿主编程语言，设计了多任务并发控制软件系统，实现了自动／半自动／手动方式的平稳切换。

Abstract The idea,design and implementation techniques of a computerized control system of in-stallations of gas processing was described.A new design of data flow and time analysis inreal time system to overcome dead and stop step phenomenon was given. Yanhua product ofcomputer-control system and the programming language C for host language were chosen,and software system of multi-task concurrent control was designed to make a smcoth cut forautomatic,half-automatic and manual ways.SUBJECT TERMS:automatie control,comtuper control,gas processing,discharge water equipment,Daqing Oilfield
