基于PLC的多路抢答器控制系统设计
摘要:本次设计利用三菱FX2N系列PLC作为核心部件,完成一个八路抢答器控制系统的制作。该系统可供八个或八组分台选手同时抢答,总台掌握着启动/停止开关、抢答开始按钮、抢答复位按钮、主持人安静提示按钮和手动设置个分台计分按钮等,分台则具有一个抢答按钮。该系统由七段数码管显示倒计时、分台号、选手计分和当前时间、温度情况,并作为被控设备由PLC驱动。因为系统中有很多七段数码管,所以我运用了动态扫描的方法来减少端口数。有一个蜂鸣器提示抢答开始、抢答复位、回答超时、抢答违规、无人抢答和安静提示。有17个发光二极管,总台一个用来显示无人抢答和回答超时,每分台两个用来显示抢答成功和抢答违规。本次设计中,硬件电路设计使用AUTOCAD软件;使用GX Developer软件编写程序;利用GX Simulator仿真软件对八路抢答器进行各部分模块仿真,观察结果。

PLC-based multi-Responder Control System Design

Abstract:The design of the use of Mitsubishi FX2N Series PLC as a ponent of this design plete an eight-way control system for the production. The ponents for eight or eight players in each group to answer at the same time Total station holds the start/stop switch, to answer in the start button, reset button to answer in the host prompts quiet buttons and manually set the scoring button sub-station and so on. Sub-station will have an answer in the button. The system consists of seven-segment LED display countdown, sub-station number, player points and the current time, temperature conditions, and as charged by the PLC-driven device. Because the system has a lot of seven-segment digital tube, so I used the dynamic scanning method to reduce the number of ports. There is a buzzer prompt to answer in the beginning, to answer in reset, the answer overtime, to answer in pliance, no one answer in his place and quiet Tips. There are 17 light-emitting diodes. with a total station 1 is used to display and answer no one to answer in overtime, each sub-units used to display the answer in his two essful and to answer in pliance. The design, the hardware circuit design using AUTOCAD software; use GX Developer software programming; the use of simulation software GX Simulator octal responder simulation of various parts of the module, observe the results.
