【正文】 尤其是 ,更適合復(fù)雜的控制系統(tǒng)。 該監(jiān)控系統(tǒng)的設(shè)計和組態(tài)軟件 MCGS 組態(tài)。 CP1H 系列可編程序控制器 (PLC)的一個簡單的控制器，它由 24 輸入和 16 個輸出。 緊急控制信號是控制交通緊急開關(guān)如果沒有緊急事件所有的紅綠燈正常工作，只是緊急事件發(fā)生的時候打開。因此，一種交通燈控制系統(tǒng)的設(shè)計 , 可以用來顯示時間的倒計時 , 與電腦聯(lián)網(wǎng)控制實時數(shù)據(jù)。正常運行和緊急運輸進 行了詳細的介紹，并從突發(fā)事件的東西南北可以相互連鎖。 eight kinds of 濱州學(xué)院本科畢業(yè)設(shè)計 (外文翻譯 ) 4 interlocking internal relay is used to implement the urgency and transmit pulse two directions to PLC, shown in the figure. Two SDEC instructions are used to display the countdown display the corresponding light. As an important part of the countdown display program, east and west of the green light reflected in the view 4 in these programs downloaded to the programmable logic controller (PLC), all the traffic lights running accuracy, urgency, and things can be interlocked from north to south strictly, all the lights can be set back to the urgency of passing state. Therefore, these control program is correct, simple. C. Monitoring System Computer system has two main functions: an output signal acquisition and display realtime status of the programmable logic controller (PLC) to control traffic lights, traffic lights. Another notification robot status and history of the state realtime curve by examining the history and alarm window. This monitoring system design and configuration software MCGS configuration is easy. The serial munication is implemented as follows. 濱州學(xué)院本科畢業(yè)設(shè)計 (外文翻譯 ) 5 Data inspection methods: double ended Serial Communications Number: COM0 ended The minimum sampling period: 200 ms Programmable Logic Controller (PLC) The parameters are defined as follows: The minimum sampling period of the basic properties: 200 ms Three read / write channel: X0, X1, X2 Six readonly access (read . traffic lights): Q0Q5 All channels must be connected to a variable defined in a realtime database access visits and other parameters to their default values. After a successful relationship, PLC and puter control system is able to change the color of
