【正文】 制器 ) 問世以前，工業(yè)控制領域中，繼電器控制占有主導地位。 第 1 章 緒論 課題 研究背景及意義 輸煤系統(tǒng)是火力發(fā) 電廠中較為龐 大 的公用系統(tǒng)。 關鍵字 ： ABplc 輸煤系統(tǒng) 料位控制 溫度控制 Abstract The subject is to design mainly based on the Rockwell Automation Laboratory’s coal power plant system and simulate system for the realization of power plant coalrelated functions. The main achievement of control are that starting the conveyor belt, material level control and temperature control. The hardware of the system includes two parts, threetier work of Rockwell PLCbased integrated framework and the objects include conveyor belt, coal bunker and Boiler the Nextbit machine, programming PLC and frequency converter on the use of RSLogix 5000、 using the work configuration software Networks to plan and municatting through RSLink systerm run in accordance with the actual coal thermal power plant. The full realization of the entire work of munication requirements, the system is running normally, successfully simulating a coal thermal power plant control system. This article provides a detailed diagram of the hardware connection 、port plans and procedures ， hope these can provide an example for the teaching demonstration. Keywords: ABplc coal power plant system material level control temperature control 1 目錄 第 1 章 緒論 .......................................................................................................... 2 課題研究背景及意義 ............................................................................... 2 本課題的設計目標和主要工作 ............................................................... 3 第 2 章 輸煤模擬系統(tǒng)設計功能的描述 ............................................................... 4 實驗室輸煤模擬系統(tǒng)簡介 ....................................................................... 4 系統(tǒng)設計功能描述 .................................................................................. 5 第 3 章 系統(tǒng)設計方案 ........................................................................................... 6 火電廠輸煤系統(tǒng)整體設計方案 .............................................................. 6 順序起停及煤位控制部分 .......................................................... 6 溫度控制部分 ............................................................................. 12 基于 ABPLC 的控制網(wǎng)絡設計方案 ..................................................... 17 羅克韋爾三層網(wǎng)絡介紹 ............................................................ 17 EtherNet 以太網(wǎng)的實現(xiàn) .............................................................. 20 DeviceNet 設備網(wǎng)的實現(xiàn) ........................................................... 21 第 4 章 系統(tǒng)線路的設計和編程 ......................................................................... 24 系統(tǒng)線路和端口分配圖 ......................................................................... 24 系統(tǒng)線路圖 .................................................................................. 24 端口分配圖 .................................................................................. 25 算法的實現(xiàn) .............................................................................................. 25 編程環(huán)境簡介 ............................................................. 25 參考梯形圖程序 .......................................................................... 27 見附錄 1 ................................................................................................. 27 第 5 章 調(diào)試修改和完善 ..................................................................................... 28 第 6 章 總結 .....................................................................................
