一、前言近年来,自动控制系统在原油长输管道过程控制中得到了广泛推广和应用,在提升运行自动化水平、提高生产效能等方面体现出了巨大优势。与此同时,原油长输管道所具有的分布地域广、现场环境复杂的特点,以及控制系统包含的仪表设备众多、逻辑功能复杂等特性,也给系统及设备的现场维护工作带来极大不便。常规的维护设备不是准确度较低,对环境条
I. Introduction In recent years, the automatic control system has been widely popularized and applied in the process control of crude oil long distance pipelines, which shows great advantages in enhancing the automation level of operation and improving the production efficiency. At the same time, the characteristics of the crude oil long-distance pipeline, such as the wide geographical distribution and complicated site environment, as well as the large number of instrumentation and control devices and complex logic functions, bring great inconvenience to the on-site maintenance of the system and equipment . Routine maintenance equipment is not less accurate to the environment
