a detection end and a receiving end, the detection end including a plurality of tire pressure detectors, and the receiving end including a tire-pressure receiving device, an in-vehicle audio-video device and a mobile device, wherein:

each of the tire pressure detectors includes a tire status detection unit, a main control unit, a radio frequency circuit and a Bluetooth circuit;

the main control unit is electrically connected to the tire status detection unit, the radio frequency circuit and the Bluetooth circuit;

the tire status detection unit continuously detects a tire status when being in operation mode;

the main control unit, upon receiving an information of the tire status from the tire status detection unit, converts the information of the tire status into a control transmission signal for output; the radio frequency circuit includes a radio frequency control unit, a radio frequency matching unit and a radio frequency antenna;

the radio frequency matching unit is electrically connected to the radio frequency control unit and the radio frequency antenna;

the radio frequency control unit, upon receiving the control transmission signal, converts the control transmission signal into a radiofrequency signal;

the radio frequency matching unit, upon signal reception from the radio frequency control unit, adjusts the control transmission signal to match a pre-set radio frequency impedance;

the radio frequency antenna matches the pre-set radio frequency impedance for maximum power transfer, and allows for output of the radio frequency signal within a corresponding frequency band to any one or any two or more of the tire-pressure receiving device, the in-vehicle audio-video device and the mobile device so as to display the tire status;

the Bluetooth circuit includes a Bluetooth control unit, a Bluetooth matching unit and a Bluetooth antenna;

the Bluetooth matching unit is electrically connected to the Bluetooth control unit and the Bluetooth antenna;

the Bluetooth control unit, upon receiving the control transmission signal, converts the control transmission signal into a Bluetooth signal;

the Bluetooth matching unit, upon signal reception from the Bluetooth control unit, adjusts the control transmission signal to match a pre-set Bluetooth impedance;

the Bluetooth antenna matches the pre-set Bluetooth impedance for maximum power transfer, and allows for output of the Bluetooth signal within a corresponding frequency band to any one or any two or more of the tire-pressure receiving device, the in-vehicle audio-video device and the mobile device so as to display the tire status;

when the tire pressure detectors of the detection end are activated in the operation mode, the receiving end, upon receiving any one of the radio frequency signal and the Bluetooth signal, sends a feedback signal to the detection end to stop output of unreceived signals, so that the tire pressure detectors of the detection end are switched from the operation mode to power-saving mode so as to reduce transmission frequency of the detection end;

when the tire pressure detectors of the detection end are activated in the operation mode and outputs the radio frequency signal and the Bluetooth signal to the receiving end, the receiving end, upon failure of completing signal reception within a specified time frame, sends a feedback signal indicating non-operation to the detection end, causing the tire pressure detectors of the detection end to switch from the operation mode to positioning mode and initiating a positioning procedure with the receiving end.
