【摘要】 本文通过对污水处理工艺的研究，开发出了“污水处理计算机集散控制系统”。该控制系统主要由上位计算机、PLC控制系统和现场智能监控仪器组成。 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；PLC控制系统主要完成工艺流程控制以及协调现场各智能监控仪器之间的逻辑关系，将现场各设备的运行状态通过通信线路传输到上位计算机，并接受上位计算机的控制指令；现场各智能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计算机进行处理、保存等。 介绍了PLC控制系统的设计方法、上位计算机的综合应用程序开发、PLC控制系统与上位计算机之间的通信的实现，讨论了现场智能单元的一般设计等问题。 本文在污水处理自动化、智能化方面作了一些探索和研究，希望对现有污水处理设备的改造、新型污水处理设备和系统的设计提供一些理论借鉴和技术参考，以提高我国污水处理设备的总体技术水平。更多还原

【Abstract】 The Distributed Computer Control System for Waste Water disposal with the research of disposal technics of waste water was introduced. The control system consists of computer PLC control system and local intelligent control instruments. The computer mainly realizes the functions of long-range supervision and management and it includes: dynamic show of technics flow, real time data acquirement and show, history data save and print, error alarm, etc; The PLC control system mainly accomplishes the technics flow control and harmonizes the logical relationship among local intelligent control instruments, and it will not only transmit the running states of local instruments to the computer ,but also receive the control commands from the computer; The local intelligent units take charge of the correlated parameter’s inspect, process and control, and it will transmit the related parameters to the computer , etc.The design method of PLC control system, the integrated program development of computer the communication between PLC control system and computer was introduced, and the common design for local intelligent units was also discussed.This paper’s purpose is to try to research the automation and intelligent for waste water disposal, and to provide some theory and technics for currently improvement of waste water disposal equipment new pattern waste water disposal equipment and design of control system. We hope it will improve the whole technics level of waste water disposal equipment for our country.更多还原
