[SCM] qiangdaqi DL : 0: 本设计是以八路抢答为基本理念。考虑到依需设定限时回答的功能，利用AT89C51单片机及外围接口实现的抢答系统，利用单片机的定时器/计数器定时和记数的原理，将软、硬件有机地结合起来，使得系统能够正确地进行计时，同时使数码管能够正确地显示时间。-The design is based on eight-way to answer in the basic concepts. Taking into account the need to set time-bound to answer according to the function, using AT89C51 microcontroller and external interface of the answer in his system, using microcontroller timer/counter timing and count of the principle, the hardware and software together organically, making the system able to correctly to carry out time, while the digital control to correctly display the time.

[SCM] sadfasd DL : 0: 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。-The design uses Mitsubishi FX2N Series PLC as a core component, eight-way Responder to complete a production control system. The system components for eight or eight players at the same time answer in Taiwan, with a total station holds the start/stop switch, answer the Start button, answer the reset button, the host quiet hint button and manually set the sub-sets of scoring buttons, etc., sub-station you have a answer in the button. The system consists of seven-segment display countdown, sub-station number, player points and the current time, temperature, and serve as driven by PLC controlled equipment. Because the system has a lot of seven-segment, so I used the dynamic scan method to reduce the number of ports. There is a buzzer to answer in the beginning, answer reset answer time out, answer in illegal, no one answer in a quiet and tips. 17 light-emitting diode, a total station is used to display and answer no answer in overtime, each sub-station to answer in two to show success and

[SCM] Eight-way-responder DL : 0: 本次设计使用了74系列常用集成电路设计的数码显示八路抢答器的电路组成、设计思路及功能。此次设计的抢答器同时供8名选手或8个代表队比赛，分别用8个按钮S1~S8表示。设置一个暂停，系统复位和抢答控制开关S，该开关由主持人控制。当其中一路抢先接通电路后，装置自动切断其他电路的信号，同时答器具有锁存与显示功能。即选手按动按钮，锁存相应的编号，并在LED数码管上显示，同时扬声器发出报警声响提示。如过倒计时二十秒后无人抢答，系统自动复位，倒计时小于五秒发出报警提示。-This design uses 74 series of common integrated circuit design of digital display circuit eight responder composition, design ideas and functions. The design of the responder for 8 players or 8 teams, respectively, with 8 button S1~S8. Set a timeout, system reset and Responder control switch S, the switch is controlled by the moderator. When one of the first circuit is switched on, the device automatically cuts off the signal of the other circuit, and the device has the function of latch and display. The players press the button, the corresponding number of latches, and display in the LED digital tube, and the loudspeaker alarm prompt. As the countdown twenty seconds after no one answer, the system automatically reset, less than five seconds countdown alarm prompt.
