通讯控制器,又名集线器、通讯处理器或通讯控制设备,是计算机网络、远程控制系统和分布式数据处理系统中的核心部分.在一个小型的油田自动化集中测量控制系统的设计和实现中,考虑到终端站多达三十五个,联网时专门设计了一个通讯控制器,以保证系统的正常工作和提高主机的使用效率. 在一个方圆约五十平方公里的石油构造内,随机地分布了二百来口油井和注水井.十几口油井和注水井汇集在一个计量站,由站内统一控制.几个计量站的输出均接到中转站,最后是油库、注水站和水源泵站.每天,主机都要打印出前一日的各项数据.终端则代替人做各种数据的采集、井位的测量、控制和报警.并通过无线电话机,每隔一个半小时,送回前一个半小时的各项数据.
Communication controller, also known as hub, communication processor or communication control equipment, is the core part of computer network, remote control system and distributed data processing system.In a small oil field automation centralized measurement control system design and implementation, Taking into account the terminal station up to thirty-five, networking specially designed a communication controller to ensure the normal operation of the system and improve the efficiency of the host in a radius of about 50 square kilometers of oil within the distribution of random A dozen oil wells and water injection wells, a dozen oil wells and water injection wells converged in a metering station, unified control by the station.A few of the metering station output are received transfer station, and finally the depot, water injection station and water pumping station Every day, the host computer prints out the data of the previous day, and the terminal replaces all kinds of data collection, well location measurement, control and alarm, and sends the data through the radiotelephone every half an hour A half-hour of the data.
