摘要
本系统由单片机最小系统、无线遥控模块、语音录入播放模块、键盘、LED显示、步进电机驱动模块组成。系统利用Freescale公司的MC9S12DG128BCPU做为主控芯片,利用其内部定时器设置定时时间,实现步进电机的调速,从而控制升降旗的时间;利用数字键预输入国旗的指定位置来实现任意位置的自动停止;升旗时能够完成升旗动作并同步播放国歌以及数字实时显示旗帜高度的基本功能。系统除上述基本功能外,还具有自动半旗、断电旗帜高度数据保持、升降旗时间可调以及无线遥控升降旗功能。
The system is consisted by Single-chip Microprocessor Minimum System, wireless remote modules, voice recording and playback module, keyboards, LED display, the stepper motor-driven module. The system uses MC9S12DG128 as CPU chip, and the internal timer is employed to set scheduled time for stepper motor, thus achieve to control the time of lifting and falling flag. It utilizes the number keys enter the national flag of the pre-designated locations anywhere to achieve automatic cut-off. While the flag raising action, the system can be completed simultaneously broadcast the national anthem and real-time display the high of the flag. Besides the basic functions, it also has the function of semi-automatic flag,displaying the high data of flag and wireless remote control .
