- 基于PLC的皮帶運輸系統監控設計（全套）2012本科畢業設計ABSTRACT
Transmission belt machines occupy a very important position in many businesses, but its control unit is variety,there is a difference between the performance and functionality. The traditional relay control of the transmission belt has complex circuits exist, poor reliability, fault diagnosis and rule out the difficulties shortcomings, in order to achieve the economic benefits of good corporate and social economic benefits,by using user-friendly,practical,strong PLC ladder (LADDER DIAGRAM) programming language on the belt transmission control system design.
The topic is introduced the apply for Series C Omron PLC in four paragraphs belt transmission system of control,it is given the hardware and software design of the PLC control belt transmission systems,including the PLC Selection,I/O address assignment, I/O terminal wiring,programming and control theory. The design of the equipment improve the reliability of equipment and reduce the failure rate,it has been successful.
Keywords：PLC；Ladder；Transmission belt machine；Automatic control; Supervisory equipment

第1章 緒 論
1.1研究現狀和研究意義
1.1.1國內外皮帶運輸機的研究現狀
國外在帶式輸送機動態分析研究方面開展得比較早,動態分析理論與研制的軟件已基本能夠滿足當前帶式輸送機發展之需；而我國相對較晚,與國外相比還存在一定的差距,尤其是動態分析軟件部分。為了盡快彌補這一差距,趕超世界水平,有必要研究和分析當今國外帶式輸送機的動態分析軟件。國外動態分析軟件目前,美國、法國、澳大利亞、意大利等國家在動態分析研究方面,已經達到國際領先地位
我國生產制造的上運帶式輸送機的品種、類型較多。在“八五”期間，通過國家一條龍“日產萬噸綜采設備”項目的實施，帶式輸送機的技術水平有了很大提高，煤礦井下用大功率、長距離帶式輸送機的關鍵技術研究和新產品開發都取得了很大的進步。如大傾角、長距離帶式輸送機成套設備、高產高效工作面順槽可伸縮帶式輸送機等均填補了國內空白，并對帶式輸送機的主要元部件進...
