详细说明： 带数字显示的抢答器控制系统设计摘 要：抢答器被广泛应用于各种知识竞赛中，传统的抢答器大部分都是基于数字电路组成的，制作过程复杂，可靠性差。本设计利用西门子S7-200系列PLC作为核心部件，完成一个六路抢答器控制系统的制作。该系统可供六名或六组选手同时抢答，总台掌握着启动/停止开关、抢答开始按钮、抢答复位按钮等，分台则具有一个抢答按钮。本系统由两组七段数码管显示抢答倒计时、抢答选手号、无人抢答闪烁，同时作为被控设备由PLC驱动。有一个蜂鸣器提示抢答开始减计时、数码显示锁存、无人抢答报警。同时该系统设计了系统结构图、梯形图以及输入输出端子的分配方案，实现了锁存、定时和报警功能，不仅电路简单，控制方便、灵活，而且保证了抢答的公平、公正原则。 关键词：抢答器 PLC LED数码管 系统 Responder with Digital Display Control System Design Abstract: Responder is widely used in a variety of knowledge contests, traditional Responder mostly digital circuits, the complex ity of the production process, poor reliability. The design of the use of Siemens S7-200 Series PLC as a core component of this design to complete an six-way control system for the production. The system components for six or six 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 and so on. The system consists of seven-segment LED display countdown, sub-station number, the current time, and as charged by the PLC-driven device. There is a buzzer prompt to answer in the beginning, to answer in reset, the answer over time, no one answer in his place. At the same time the design contents the system structure diagram, ladder, and the input and output terminals of the distribution plan, and to achieve the latch, timer and alarm, not only simple circuit easy to control, flexible, but also to ensure the answer in the fire and just principles. ...展开收缩
