The invention discloses an automobile tire monitoring system and a low-power-consumption alarming method thereof. The system comprises a tire monitoring sensor, a low-frequency matching module and a radio frequency matching module, wherein the tire monitoring sensor is used for detecting pressure, temperature, accelerated speed and voltage information; the low-frequency matching module is connected to the input end of the tire monitoring sensor by using an RLC (Radio Link Control) parallel resonance circuit; the radio frequency matching module is connected to the output end of the tire monitoring sensor by using a multi-grade LC (Launch Control) matching network; and the radio frequency matching module is matched with an automobile inflating valve antenna so that the optimal launching power is realized. According to the automobile tire monitoring system, the signal launching power can be greatly increased through the radio frequency matching module and the service life of a battery can be greatly prolonged through a designed alarming strategy.
