自动化综合实训设备载体设计与制作—8路抢答器
摘要：文章介绍一种利用日本三菱公司生产的FX3U-48MT 型PLC 作为核心控制器的自动化综合实训设备载体设计与制作—八路抢答器，其中还有人机界面模块，PLC模块，电源模块，设备载体模块又分为按钮子模块、指示灯子模块、数码显示模块，并且给出了系统组成模块、外部接线图、梯形图以及输入输出端子的分配方案。该实训设备载体具有基本的抢答功能，报警功能，还具有数字显示功能。其中抢答器的工作原理：当主持人发布抢答命令后，若有人按下按键，这时通过程序判断且在数码管显示先按键的人，这时其他人将不能进行按键作。并且答题人要在规定的时间内给出正确答案。当要进行下一次抢答时，由主持人按复位键，电路复位，进入下一次抢答。该电路具有工作稳定可靠、响应速度快、实时性强等特点。主要是为了给高校学生进行自动化综合实训设备提供更加系统的学习，可以快速提高学生的认知和思考能力，培养大家的发散思维。

Abstract:Article introduces a way to use Japan mitsubishi company production of FX3U - 48 mt type PLC as the core controller of automatic comprehensive training equipment carrier - eight-way vies to answer first device design and manufacture, including man-machine interface module, PLC module, power module, equipment carrier is divided into button module, module module, digital display module, and gives the system module, external wiring diagram and ladder diagram and the distribution of the input and output terminals. The training equipment carrier has basic vies to answer first function, alarm function, also has the function of digital display. The buzzer working principle: when the host orders issued vies to answer first, if they press the button, then to judge by the program and in digital tube display button first, then others will not be able to button. And the answer should be within the prescribed period of time given the right answer. When to be next time vies to answer first, by the host according to the reset button and reset circuit, into the next time vies to answer first. The circuit is stable and reliable work, fast response speed, strong real-time performance, etc. Mainly for university student to carry on the comprehensive training equipment automation provide more systematic learning, can quickly improve the students' cognitive and thinking ability, to cultivate divergent thinking.
Keywords:Comprehensive training equipment automation; PLC; Eight-way vies to answer first function; Digital display function
