基于STM32的多路抢答器设计与制作
Design and Make of Multiple Answering Device on STM3
内容摘要
抢答不仅仅需要参与者，还需要裁判，而裁判的作用是整个过程中是最终要的，他是影响结果的一个很重要因素，在古代，裁判只能通过肉眼去判断谁先抢答，但是人的肉眼的能力是有限的，很难精准的得出正确的选择，如果出现相差不大的情况，裁判很容易就会错判，导致结果的错误而改变。而随着时代的不断变化，人们也想到很多去增加判断的精确度的方法，如敲锣，打鼓等都被应用到抢答中，这时候裁判的判断点又多了一个，但是这还不够精确，错判的几率相对来说还是有些大，而随着时代的变更发展，敲锣打鼓和肉眼已经不能够满足人们对于抢答精准的需求，随着发展，以按键配合二极管为主的抢答器就出现了，它从一开始的单路按键功能简单到多路按键功能复杂，然后慢慢出现以单片机为核心的多路抢答
器，再蜕变成从有线连接到无线连接的多路抢答器，从结构复杂功能简单到结构简单功能繁多，它一直在随着时代的发展而在不断改进中，人们对于抢答器的功能的要求增长越来越高，抢答器的更新换代也越来越快，它的功能和精准度也就变得越来越多。
本文是基于STM32的多路抢答器的设计与制作，它支持多线路抢答，可以精确判断哪一路先完成抢答，人可以通过1602LCD液晶显示，LED灯，数码管看到哪一个是第一抢答者，抢答者面前的灯会亮起，LED显示屏会显示抢答者的信息，数码管会显示可回到倒计时，在裁判进行复位前全部抢答者不能进行操作； 当回答时间快要结束时，蜂鸣器会发出警告和LED灯的闪烁来提醒参赛者和裁判时间快结束了，当时间到达后，抢答者面前的灯将会熄灭，这时候裁判可通过按下复位键，让抢答者们可以重新操作，进行下一轮抢答。

Abstract
Responding not only requires participants, but also the referee, and the role of the refere
e is the final one in the whole process. He is a very important factor affecting the result. In ancient times, the referee can only judge who responded first by the naked eye, but the person The ability of the naked eye is limited, it is difficult to accurately draw the correct choice, if there is not much difference, the referee will easily misjudge, leading to wrong results and change. With the continuous changes of the times, people also think of many ways to increa the accuracy of judgments, such as knocking gongs, playing drums, etc., are applied to the answer. At this time, the referee has one more judgment point, but this is not accurate enough. The probability of misjudgment is still relatively large, and with the development of the times, drumming and drumming and the naked eye have been unable to meet people's demand for accurate answering. With the development, answering devices bad on buttons and diodes are mainly ud. Appeared, it was from the beginning of the single-channel key function is simple to multi-channel key function is complex, and then slowly appeared multi-channel answering device with the single-chip as the core, and then transformed into a multi-channel answering device from wired connection to wireless connection, from The structure is complicated and the function is s
imple to the structure is simple and has many functions. It has been constantly improving with the development of the times. The requirements for the function of the answering device are growing higher and higher, and the updating and updating of the answering device are getting faster and faster. The functions and precision of the UPS become more and more.
This article is bad on the design and production of STM32 multi-channel answering device, it supports multi-line answering, you can accurately determine which way to complete the answering first, people can e which one is the first responder through 1602LED LCD display, LED lights, digital , The light in front of the responder will light up, the LED display will show the information of the responder, the digital tube will show that it can return to the countdown, and all the responders cannot operate before the referee rets; A warning and a flashing LED light will be issued to remind the contestants and the referee that the time is almost over. When the time is up, the light in front of the responder will go out. At this time, the referee can press the ret button to allow the responders to re-operate For the next round of rush answers.
