Abstract :
This paper introduces a kind of radio alarm design which based upon MCU. IC NRF401 used in this alarm which can transmit & receive signal. P89LPC930 which has high-speed procession and A/D converter which has high-precision are all used in this alarm. So the design can realize the many kinds of alarm signals´ intelligent acquisition and procession. This paper shows us the design of receiving & transmitting hardware circuits and software flow chart. This design mainly used in coal-mines and underground garages´ alarm system, and it also can be used widely.
