| The thing existing inevitably has reasonable. In the modern water industry, with the urgent request of the sewage treatment for the operation and the management automation and the self-advantage of the computer supervisory system in the industrial automation domain sewage treatment and the computer supervisory system closely are unified in together. The advanced reasonable automatic control system may enormously reduce operator's labor intensity, reduce possible accident and hidden danger which the human factor brings, guarantee the sewage treatment water quality, enhance the working efficiency, enhance the enterprise the production automation level and the scientific quantification. So that it makes the enterprise fit to the tense competition.The emergence of a series of new equipment and the new technology, such as the PLC programmable controller, the simulation screen, monitor the computer, the industry ethernet, configuration software and so on causes the industrial automation possibly to become. The programmable controller especially is suitable for the sewage treatment plant because this kind of electromechanical device variety multi- quantities greatly dispersible needs the real-time monitor enterprise. After more than 30 years development, now this product software and hardware already quite consummated, already more and more was mature in the industry domain utilization. The Changchun sewage treatment computer supervisory system uses the open style system, the lamination structure which the host control room to establish two monitorings computers (ä¸Šä½æœº) ,five PLC substation, the multitudinous programmable controller (PLC), the 100M auto-adapted single link optical fiber net. All these compose... |
