基于现场总线的油库监控系统研发

面对油库传统设备多的现实,在我国油库自动化水平亟待提高的背景下,应用基于现场总线的Sie-mens自动化技术构建了油库监控系统。介绍了PROFIBUS现场总线与AS i总线的特点、长处以及它们在整个SCADA系统中所处的不同位置和所起的不同作用,从而两者集成而构建的监控系统不仅使得通信、控制更趋流畅、有效,而且使得对现场安全情况的监视更加可靠,另一方面,本监控系统适合我国油库设备现状,并且已成功应用于油库。

Research and Development of Supervision and Control System in the Oil-storage Based on Fieldbus

With the reality that the oil-storage devices are mostly traditional,and on the background that the automation standard of oil-storages in our country should be raised immediately,an oil-storage supervision and control system is established by applying Siemens automatic technology which based on fieldbus.The features and advantages of PROFIBUS and ASi bus technologies are introduced,as well as their different locations and functions in the whole SCADA system,as a result,the SCADA system with the integration of the two kinds of technologies above not only makes the communication and control actions more effective,but also render the supervision of local security situation more reliable,on the other hand,it adapts to the fact of oil-storage instruments in our country.This system has already been applied in an oil storage successfully.
