摘要
针对钻井现场地面数据种类多样化的特点,设计一种基于最新的工业以太网标准PROFINET的地面数据采集系统,采用西门子PLC1200做为数据采集核心处理单元,可兼容常规总线如PROFIBUS总线和以太网设备,克服传统数据采集装置硬件设计单一,不易于扩展,兼容性差等缺点,实现从管理级到现场IO设备的“一网到底”,并可兼容工业以太网设备。本设计具有数据传输可靠稳定,现场使用灵活,可方便扩展系统等诸多优点,可在钻井现场环境数据监控及采集处理中发挥重要作用。
According to the characteristics of data diversity of drilling site, this paper designs a data acquisition system which is the latest industrial Ethernet standard based on PROFINET, using SIEMENS PLC1200 CPU as the core data acquisition processing unit, compatible with conventional bus such as PROFIBUS bus and Ethernet equipment, to overcome disadvantages of simple hardware design of the traditional data acquisition system, expansion and poor compatibility. The design can realize the management from the site IO equipment to man-machine interface in PROFINET network, and can be compatible with industrial Ethernet equipment. The design has many advantages, such as reliable and stable data transmission, flexible field usage and easy expansion of the system. It can play an important role in monitoring, collecting and processing the data in the drilling site.
