The industrial computer mainly implements the functions of long - range supervision and management it includes : dynamic show of technics flow , real time data acquirement and show , history data save and print , fault alarm , etc ; the plc control system mainly accomplishes the wastewater technics flow control , harmonizes the logical relationship among local intelligent control instruments and transmits the state of each local equipment to the industrial computer , simultaneously , the plc control station receives the control commands from the industrial computer ; the local intelligent units take charge of the correlated parameters " measure > disposal and control , and it will transmit the related parameters to the computer , etc . in this thesis , introduced municipal wastewater treatment technics , the integrated application program development of computer , the design method of plc control station , the communication between plc control system and computer , and the network of wastewater treatment with industrial ethernet was also discussed 上位计算机主要实现远程监测和管理功能，具体包括：工艺流程动态显示、实时数据获得及显示、历史数据存储与打印、故障报警等功能； plc控制系统主要完成工艺流程控制以及协调现场各智能仪表之间的逻辑关系，将现场各设备的运行状态通过通讯网络传输到上位计算机，并接收上位计算机的控制指令；现场各智能仪表单元负责各相关参数的监测和处理、控制，并将有关参数送往上位监控计算机进行处理、保存等。本论文介绍了城市污水处理工艺、上位监控计算机的综合应用程序开发、城市污水处理自动控制系统plc控制站的设计和采用工业以太网技术的污水处理通信网络。
The research project in this thesis is " study on measurement and control system for vacuum magnetic switchgear based on intel 80c196kb " , which is a continuation project of " study on measurement and control system for vacuum magnetic swichgear based on plc " and is sponsored by education committee , science and technology committee of shanxi province . the reason why this project is put forward is because the cost of plc measurement and control system is high , and it is not adaptable to large - scale production . the main contents of this project is aimed at solving the key problems of centralized control and integrated protections of high capacity motors used in high yield and efficiency automation coal faces 本文研究的内容是“基于intel80c196kb控制的矿用真空磁力控制站测控系统的研究” ，它是山西省科技攻关项目“基于plc控制的矿用隔爆兼本质安全型组合磁力控制站的研究” (项目编号为no . 20002013 )的后续课题，主要是针对plc控制系统成本高，不利于规模化生产的缺点而提出的，该课题的研究内容主要是解决矿井高产高效综合自动化采煤工作面大型电动机的集中控制和保护等问题。
In a remote communication system , the action taken by a control station whereby messages addressed to an inoperative station are accepted and stored at the control station until they can be sent to the destination station . the control station may be a computer in a message switching system 在远程通信系统中，当报文发往的工作站处于不工作状态时控制站所采取的行动，即接收并存储该报文直到该工作站恢复工作时，再由控制站将报文送给它。在报文交换系统中，控制站可以是一台计算机。
