摘要
串行通讯技术在石油和天然气工程的智能检测仪表和控制系统中正在得到大量的应用。文章在分析RS485串行通讯技术特点的基础上,结合RS485串行通讯技术在中东某油田的应用实例,简要论述了智能仪表选型、串行通讯链路的工程设计方法。
The serial communication technique is widely used in the smart instrumentation and control devices of petroleum engineering. Based on the analysis of RS485 serial communication technical characteristics,this paper takes the application of this technique in a certain Middle East oilfield for example to demonstrate the type selection of smart instrumentation and the engineering design method of serial communication chain.
