STC89C52单片机射频的8路无线抢答器设计+电路图+程序

摘要：抢答器在生活中扮演着重要的角色，对于不同的场合，自然使用的抢答器风格也不一样。抢答器种类的多样化也使得比赛现场更加具有趣味性。抢答器的作用就是是比赛更加具有公平性，不然的话仅凭肉眼是很难判断出谁第一个抢答的，容易出现误差。然而从目前的抢答器市场来看，存在很多不足之处。许多抢答器在设计上十分复杂，线路也十分繁琐。因此在后期的使用中容易出现状况。因此在整个抢答器布置的过程中自然就加大了难度，同时也不美观了。所以本课题设计了基于射频的8路无线抢答器。我们以单片机为控制核心设计基于射频的8 路无线抢答器。在这次抢答器的设计中，主要使用N R F 2 4 L 0 1无线模块电路作为控制器。利用S T C 8 9 C 5 2 单片机作为数据处理中心。最后通过上位机将抢答结果显示在电脑屏幕上。76872

Eight wireless responder based on RF

Abstract：The buzzer plays an important role in our daily life, for different occasions, natural use buzzer style is different also。 Buzzer types of persification makes the game more interesting。 The role of the buzzer is the game more fair, otherwise just by the naked eye is difficult to determine who the first vies to answer first, prone to error。 However, from the responder market, there are a lot of disadvantages。 Many responder on the design is very complex, the line is also very complicated。 So it's easy to have a situation in the later use。 Therefore in the process of the buzzer to decorate naturally increased the difficulty, also not beautiful。 So this topic design 8-way wireless vies to answer first device based on radio frequency。 We design with the single chip processor as the nuclear heart 8-way wireless vies to answer first device based on beam frequency。 In the design of the buzzer, mainly using N R 2 4 L 0 F 1 wireless module circuit as a controller。 Using 5 S T C 8 and 9 C 2 single chip machine as a data processing center。 At last, by PC will vies to answer first the results displayed on a computer screen。
