电铃在实际生活中应用广泛，但是手动控制打铃可靠性差，噪声多，而且单独布线浪费工时和成本，为了解决可靠性差、减少不必要的噪声及布线问题，该设计主要介绍了一种以EasyARN11138单片机为核心，以七段数码管显示年、月、日、时、分和星期，时钟芯片DS12887计时并校时的无线电铃控制器。单片机根据时钟信号及事先编好的打铃表来控制发射端编码芯片PT2262发射信号，据此相应的接收端解码芯片PT2272接收信号，控制电铃工作。此设计还可以通过按键校时、选表，并留有扩展功能，使无线自动控制打铃器更贴近实际，更人性化。

Bell is widely used in actual life. However, poor reliability of manual control ring a bell, more noise, and separate wiring to waste hours and costs, in order to solve the wide application of poor reliability, reduce noise and wiring, the design mainly introduces a radio and bell controller： an EasyARM1138, with seven segment digital tube that year, month, day, hour, minute, and week ,the clock chip code DS12887 time counting and correcting time. MCU clock signal and according to pre-programmed to control the fight bell table encoding chips PT2262 transmitter emission signal, whereby the corresponding receiver decoder chip PT2272 received signal, control, electric bell work. This design can also corrects time, selects table, and leaves extensions to ring a bell wireless control device closer to the real, more humanize.
