时钟无线混合控制开关的设计与实现

以STC89C52单片机作为核心控制器,基本定时开关功能通过DS12CR887时钟芯片提供的时间标准与设定时间的比较结果控制继电器来实现开启和关断用电器,遥控功能通过SC2272解码芯片无线遥控来实现电器的开关,按键可以对实时时间,定时时间,模式选择等进行设置,开关由继电器控制交流电的开关,LCD1602显示相关定时信息和模式。从而保证了电器在各种场合下都可以不过度浪费电,也解决了人不在时的麻烦。

On the Clock P.adio Mix Control Switch

Taking STC89C52 microcontroller as the core controller, basic timer switch function are relayed to achieve open and shut off the electrical appliances by time standards and setting the time comparison result provided by the DS12CR887 clock chip to control relay, the remote control function to realiTe the wireless remote control elec- tric switch by the SC2272 decoding chip, button can be on time, timing, mode selection setting a switch is controlled by the relay, AC, LCD1602 display timing information and mode. In order to ensure the electrical appliance can not excessive waste of electricity on various occasions, but also solve the people not in trouble.
