1. A wireless tire pressure monitoring system comprising:
a wireless tire pressure sensor for being installed to a wheel rim of a vehicle, the wireless tire pressure sensor including a sensor and an emitter;
a wireless host for being installed to the vehicle, the wireless host including a circuit controller and a first receiving/emitting member, the circuit controller including a function of allocation by signals received, the first receiving/emitting member receiving signals from the wireless tire pressure sensor;
a wireless receiver connected to the wireless host and the wireless tire pressure sensor by a wireless system, the wireless receiver located at a position different from a position of the wireless host, the wireless receiver including an operation module and a second receiving/emitting member, the second receiving/emitting member receiving and emitting signals, the second receiving/emitting member detecting a phase angle of the signals from the emitter and the second receiving/emitting member, the circuit controller calculating a position of the wireless tire pressure sensor by the phase angle;
wherein the wireless tire pressure sensor sends signals to the first receiving/emitting member and the second receiving/emitting member by the emitter, the first receiving/emitting member and the second receiving/emitting member detect strength of the signals emitted from the wireless tire pressure sensor, the first receiving/emitting member and the second receiving/emitting member send the signals received from the wireless tire pressure sensor to the circuit controller and the operation member to be analyzed, the operation member forwards a result of the analyzed signals to the first receiving/emitting member and the circuit controller in sequence by the second receiving/emitting member.
