摘要
本文研讨基于西门子S7-300控制器的油田计量站自动量油系统的设计。系统针对油田恶劣的环境气候和所处的地理位置研制,运用西门子S7-300系列大型PLC控制器.具有先进的计量程序、优良的通信能力。而且具有性能稳定、安装方便等优点。特别适用于油田恶劣的温度和湿度环境。本系统能够实时采集现场数据,接收上位机和人机界面的指令自动完成量油任务,并且在出现异常情况自动处理,真正实现了现场无人值守。
This paper designed an automatic metering system scheme for oilfield metering station based on Siemens Programmable Logic Controller （PLC） 300. As the system aimed at the hardly environment and location of oilfield, it can collect information real time, receive the command from host computer and human-machine interface, and then accomplish oil- metering task, besides, deals with unnormal situation automatically, and realizes really unattended operation.
