In addition, this thesis introduces the control system's software programming process briefly from the following aspects : the touch panel's software design, the profffius master station and slave stations " control software design . and, it also gives the corresponding control flowcharts 此外,本文從觸摸屏組態(tài)軟件的設(shè)計(jì)、profibus主站及從站控制程序設(shè)計(jì)等幾個(gè)方面簡(jiǎn)要介紹了控制系統(tǒng)的軟件設(shè)計(jì)過程,并給出了相應(yīng)的控制流程圖。
From the introduction of the structure and characteristic of dcs, the analyzing in process and control peculiarity of huaxin type cement kiln and the analyzing in the ordinary forms of computer control system in the cement plant, to determine the feasibility of application of the dcs in computer control system of huaxin type cement kiln; introduced the structure of the system hardware, constitutes and characteristic of the industrial network, the characteristic and the performance in industrial control system of the software system; illuminated the whole course of the design and the application of simatic s7-300 programmable controller in the industrial producing process profoundly : the protraction of a control flowchart; the confirmation of the control scheme in every cell; how to workout a table of the all controlling and measuring dots in the control system; how to set up a plc control project; the configuration of the hardware and the network in project; illuminated the course of how to program the plc control program in detail; how to establish a connection between the plc and the programmer; how to download the configuration and the program of the plc project; the configuration of control center software simatic wincc; the whole course and the methods of the control system debugging; illuminated the essential in the course of the design in project and program; illuminated the problem and its respondence maybe encountered in the project; illuminated the superiority of the new control system in inspecting, operating and its stability; discuss the development of the computer control system in the application of the huaxin type cement kiln 從介紹了dcs的結(jié)構(gòu)、特點(diǎn)和分析華新型水泥窯的工藝控制特點(diǎn)及當(dāng)今在水泥窯計(jì)算機(jī)控制系統(tǒng)上采用的幾種常見形式的比較出發(fā),分析了在華新型水泥窯應(yīng)用dcs的可行性;詳細(xì)介紹了系統(tǒng)硬件結(jié)構(gòu)、網(wǎng)絡(luò)組成及特點(diǎn)、所采用的軟件體系的特點(diǎn)及其在工業(yè)控制應(yīng)用中的性能;深入詳細(xì)地說明了西門子s7-300可編程序控制器在華新型水泥窯控制上應(yīng)用及設(shè)計(jì)的全過程:控制流程圖的繪制;單元控制方案的確定;系統(tǒng)控制測(cè)點(diǎn)表的編制;plc控制項(xiàng)目的建立;項(xiàng)目硬件及網(wǎng)絡(luò)的組態(tài);plc控制程序的編制過程并詳細(xì)說明了控制程序的編制思路;plc與編程器連接的建立;plc項(xiàng)目組態(tài)及控制程序的下載;wincc監(jiān)控軟件的組態(tài);控制系統(tǒng)的調(diào)試過程及方法;對(duì)設(shè)計(jì)和使用的要點(diǎn)及系統(tǒng)調(diào)試時(shí)應(yīng)注意的問題進(jìn)行了說明;對(duì)項(xiàng)目的實(shí)施后的華新型水泥窯控制系統(tǒng)在操作和控制上及其在系統(tǒng)易維護(hù)性、系統(tǒng)穩(wěn)定性上的優(yōu)勢(shì)進(jìn)行了說明并討論了華新型水泥窯計(jì)算機(jī)控制系統(tǒng)的發(fā)展方向。
