摘 要

自動(dòng)化傳輸線是工業(yè)生產(chǎn)過程中最常見的設(shè)備之一。自上個(gè)世紀(jì)60年代PLC問世以來，由于其在控制方面的優(yōu)點(diǎn)，目前利用PLC作為核心控制器件的工業(yè)應(yīng)用越來越廣泛，本論文對(duì)PLC及其相關(guān)的外圍器件進(jìn)行了研究，提出了基于PLC的自動(dòng)化傳輸線控制系統(tǒng)框架。

   根據(jù)自動(dòng)化傳輸線的運(yùn)行要求，本論文設(shè)計(jì)了一種利用PLC（松下FP1）作為主控器件，包含移載、頂升和提升三個(gè)基本環(huán)節(jié)的自動(dòng)化傳輸控制系統(tǒng)。首先闡述了PLC及接近開關(guān)、行程開關(guān)等外圍器件的工作原理，然后介紹了自動(dòng)化傳輸線各個(gè)部分的工作原理及整體框圖。在此基礎(chǔ)上，選擇出相應(yīng)的硬件并簡(jiǎn)單介紹其技術(shù)參數(shù)，根據(jù)其原理設(shè)計(jì)出自動(dòng)化傳輸線的硬件控制框圖，并利用FPWIN-GR軟件編寫了相應(yīng)的梯形圖程序。

   通過實(shí)際調(diào)試運(yùn)行，該系統(tǒng)運(yùn)行穩(wěn)定，安全可靠，取得了較好的效果，達(dá)到了實(shí)際運(yùn)行要求。

ABSTRACT

  Automation transmission line is in the industrial production process one of most common equipment. Since on century 60's PLC being published, as a result of it in the control aspect merit, has at present controlled the component using PLC as the core the industrial application to be more and more widespread, the present paper has conducted the research to PLC and the correlation periphery component, proposed based on the PLC automated transmission line control system frame.

According to the automated transmission line movement request, the present paper designed one kind using PLC (Panasonic FP1) to take the master control component, contained moves carries, goes against rises and promotes three basic links the automated transmission control systems. First elaborated periphery component and so on PLC and close switch, limit switch principles of work, then introduced the automated transmission line each part of principle of work and the overall diagram. In this foundation, choice showing off should the hardware and introduced simply its technical parameter, designs the automated transmission line according to its principle the hardware control diagram, and has compiled the corresponding

Trapezoidal chart procedure using the FPWIN-GR software.

Through the actual debugging movement, this system movement is stable, safe reliable, has obtained the good effect, has met

the actual movement requirements.


Key words: transmission line; PLC; FP1; close switch; limit switch; FPWIN-GR; trapezoidal chart
