摘　　要：本文介绍了一种基于HT48R10A单片机的风机转速测量、报警系统的硬件电路设计以及软件实现。当低于一定转速时,发光二极管LED将间断性闪烁、蜂鸣器报警,以提示工作人员及时检查风机的运行情况。该系统已成功应用于雷达控制系统中的风机转速监测,确保雷达控制系统的正常运行。A fan speed measurement and alarm system is introduced in this paper. The hardware design and software design of the system are presented. When the fan speed is lower than a given threshold,the light emitter diode LED will glitter discontinuously,and the buzzer will give out an alarm sound. So the stuff can find the abnormal fan and replace it with a good one. The system has been used in the cooling system of the radar control system successfully. It can make sure that the radar control system can run norma...
