说明：  作息时间控制系统软件设计以时钟显示为主程序，以读时钟芯片的时间信息、给数码显示管送显示信息、键盘扫描、时间比较控制为子程序。在设计中利用单片机时钟计时集成电路完成计时的任务，并500ms向单片机发一个中断，中断子程序有时钟显示及时间比较，如比较相等，则说明作息时间已到，发出指令控制电铃或照明电路的开、关操作。
(Rest time control system software designed to display the main program the clock to the time clock chip read information sent to the digital display tube display information, keyboard scanning, time subroutine more control to. In the design of integrated circuits using single chip clock time to complete the task time and 500ms send an interrupt to the microcontroller, interrupt routines and spend more time with the clock display, such as relatively equal, it indicates the time has come to rest, give directions bell or lighting circuits control The opening and closing operation.)
