八路抢答器的PLC控制(含plc梯形图)(含任务书,毕业论文11000字,cad图纸)
摘 要
抢答器的定义，即在竞赛、文体娱乐活动（抢答活动）中，能准确、公正、直观地判断出抢答者的机器。在现今社会里，抢答器在娱乐节目、拍卖会等场合越来越得到重用，它可以帮助改善工作方式，方便思想的快速交流，使工作效率得到较大的提升。只要按一下按钮就能轻松的表达自己的想法，简单快捷。充分利用科学技术为生活服务，是现代社会发展的方向。
实现抢答器功能的方式由多种，可以采用早期的模拟电路、数字电路或模数混合电路。近年来随着科技的飞速发展。单片机、PLC的应用不断地走向深入。同时带动传统的控制检测技术的不断更新。现介绍的就是一种利用日本三菱公司生产的ＦＸ２Ｎ－６４ＭＲ型PLC作为核心控制器的八路抢答器系统。给出了系统结构图、梯形图以及输入输出端子的分配方案。

ANSWER EIGHT-WAY PLC DEVICE CONTROL
ABSTRACT
Answer's definition, that is, in the contest, style entertainment (Answer activities) in an accurate, fair and visually determine the machine Answer. In today's society, Answer in entertainment, the auction will be increasingly important and so on, it can help to improve the working methods to facilitate the rapid exchange of ideas, so that a greater work efficiency improved. Just click the button will be able to easily express their ideas, simple and quick. Make full use of science and technology services for the life of modern social development.
Answer feature to achieve a combination of methods can be used early analog circuits, digital circuits or analog-to-digital hybrid circuits. In recent years, with the rapid development of science and technology. Single-chip, PLC applications to continue to depth. At the same time, the control of traditional detection technologies constantly updated. Are introduced is a production of Japan's Mitsubishi FX2N-64MR-based PLC as the core of the eight-way controller system Answer. The system structure diagram, ladder diagram, as well as the distribution of input and output terminal program.
