本科毕业论文（设计）题目混料传送带PLC控制系统设计与安装

摘要

介绍了PLC在四节传送带控制系统中的应用，同时也详细地叙述了系统中相关控制项目的设计方案及具体实现方法。文中还介绍了基于PLC与单片机的区别使我们能更加的清楚认识PLC，对学生熟悉PLC控制系统的结构和工作原理以及学习梯形图的编写都有很大的帮助。

本系统是对四节混料传送带控制的系统，该设备适用于流水线生产等，也可以把生产出的货物进行传送到特定的地方。

高可靠性是电气控制设备的关键性能。PLC由于采用现代大规模集成电路技术，采用严格的生产工艺制造，内部电路采取了先进的抗干扰技术，具有很高的可靠性。从PLC的机外电路来说，使用PLC构成控制系统，和同等规模的继电接触器系统相比，电气接线及开关接点已减少到数百甚至数千分之一，故障也就大大降低。此外，PLC带有硬件故障自我检测功能，出现故障时可及时发出警报信息。在应用软件中，应用者还可以编入外围器件的故障自诊断程序，使系统中除PLC以外的电路及设备也获得故障自诊断保护。

Abstract

Introduced PLC in four conveyer belts control system application, simultaneously also in detail narrated in the system to be connected the control project design proposal and the concrete realization method. In the article also introduced enables us based on PLC and the monolithic integrated circuit difference even more clearly to know PLC, is familiar with the PLC control system to the student the structure and the principle of work as well as the study trapezoidal chart compilation all has the very big help.

This system is a system which controls to four conveyer belts, this equipment is suitable for the production-runs and so on, also may the cargo which produces carry on transmits to the specific place. The redundant reliability is the electricity control device essential performance. PLC because uses the modern large scale integrated circuit technology, used the strict production craft manufacture, the internal circuit has adopted the advanced antijamming technology, had the very high reliability. Machine the external circuit said from PLC that, uses the PLC constitution control system, compares with the same level scale relay system, the electrical wiring and the switch contact reduced to several hundred even several 1/1,000, the breakdown also greatly reduces. In addition, PLC has the hardware breakdown self-examination function, appears when the breakdown may promptly send out the warning information. In the application software, the application also may enroll the periphery component the breakdown from the diagnostic program, causes in the system also obtains the breakdown besides PLC electric circuit and the equipment from the diagnosis protection
