<p>PROBLEM TO BE SOLVED: To provide an electronic equipment starting device which does not perform useless power consumption except when used and a vehicle tires monitoring system that eliminates the useless power consumption of a battery of a detecting device by using the electronic equipment starting device. SOLUTION: This vehicle tires monitoring system uses electromagnetic waves to transmit a start signal from a monitor every period of time T1, the detecting device 3 that receives the start signal converts high frequency electromagnetic force induced in an antenna 31 with the start signal into electric energy with a rectifier circuit 33, a central processing part 34, a detecting part 35 and a transmitting part 36 are driven with the power, the central processing part 34 that starts driving sets a FET 382 to be on to feed power to a sensor part 38 from a battery 381 and the sensor part 38 is made to operate.</p> |
