中 州 大 学 工 程 技 术 学 院 可编程控制器课程设计 设计题目： 抢答器PLC控制系统设计 专 业： 电气自动化 班 级： 08电气（2）班 姓 名： 学 号： 指导教师： 摘要 可编程序控制器(PLC) 是一种新型的通用的自动控制装置,它将传统的继电器控制技术、计算机技术和通讯技术融为一体,是功能加强、编程简单、使用方便以及体积小、重量轻、功耗低等一系列优点。 近年来随着科技的飞速发展，PLC的应用正在不断地走向深入，同时带动传统控制检测日新月益更新。在实时检测和自动控制的PLC应用系统中，PLC往往是作为一个核心部件来使用，仅PLC方面知识是不够的，还应根据具体硬件结构，以及针对具体应用对象特点的软件结合，加以完善。 PLC的应用领域已经拓宽到了各个领域，在日常生活中，智能抢答器广泛的应用于各种竞赛和抢答场合。越来越多的抢答器投入市场，可是大部分的抢答器主要采用的是单片机系统；而单片机系统由于稳定性不高，所以我们设想是否可以利用PLC进行抢答器的设计，所以我们小组针对此次毕业设计进行了软硬件的设计。基于此，我们采用了欧姆龙公司的PLC 来实现智能抢答器控制系统的设计。 关键词： 抢答器 PLC 自动控制装置 summary Programmable logic controller (PLC) is a new kind of general automatic control equipment, it will traditional relay control technology, computer technology and communication technology, and is a function, use convenient and simple programming, small volume, light weight, low power consumption, a series of advantages. In recent years, with the rapid development of science and technology, the application of PLC is continuously to further, traditional control test on new PE updates. In real-time detection and automatic control of PLC system and PLC is often used as a core component of PLC, knowledge is not enough only, still should according to specific hardware structure, and in light of the specific characteristics of the object software application, perfected. PLC application domain has widened to each domain, in daily life, intelligence contest is widely used in various competitions and vies to answer first occasion. The contest is more, but most of the investment market is mainly adopts the responder SCM system is, Due to the stability and single-chip microcomputer system is not high, so we can imagine use PLC to design contest for the team, so our graduation design of hardware and software design. Based on this, we adopted omron PLC to realize the intelligence of the company control system design contest. cKeywords: vies to answer first editor PLC automatic control device 第二章 抢答
