The transceiver host 100 includes a processing unit 110, a host Bluetooth transceiver unit 120 and a transceiver host antenna 130. In which, the host Bluetooth transceiver unit 120 is electrically connected to the processing unit 110 and the transceiver host antenna 130. Each of the Bluetooth tire pressure detectors 200 includes a battery 210, a monitoring module 220, a control unit 230, a Bluetooth transceiver unit 240 and a transceiver antenna 250. The battery 210 is electrically connected to the control unit 230 and the monitoring module 220, and the control unit 230 is electrically connected to the monitoring module 220. The Bluetooth transceiver unit 240 is electrically connected to the control unit 230 and the transceiver antenna 250. Further, the control unit 230 includes a locating program 230 and a tire condition program 232. The data detected by the monitoring module 220 is obtained by the locating program 231 and the tire condition program 232. Moreover, the transceiver host antenna 130 of the host Bluetooth transceiver unit 120 and the transceiver antenna 130 of the Bluetooth transceiver unit 240 constitute a duplex Bluetooth packet transmission. The host Bluetooth transceiver unit 120 of the transceiver host 100 controls the control unit 230 to start or stop the locating program 231 and limit the packet transmission of the tire condition program 232.

[0020] For example, the transceiver host 100 mentioned above is located inside the vehicle, and the Bluetooth tire pressure detector 200 is mounted on the tire of the vehicle (which can be either an inner side or an outer side). The monitoring module 220 includes a pressure monitoring unit 221, a temperature monitoring unit 222, a gravity monitoring unit 223 and a voltage monitoring unit 224. Through the pressure monitoring unit 221, the temperature monitoring unit 222, and the gravity monitoring unit 223, information for assisting in locating can be detected, such as tire pressure, temperature, acceleration, rotation time, rotation phase, and tire position, etc. In addition, the voltage of the battery 210 can be detected through the voltage monitoring unit 224, so as to prevent the voltage of the battery 210 from being lower than the operating voltage of the monitoring module 220 and the control unit 230, and prevent abnormality or insufficient power in the battery 210.

[0021] When the transceiver host 100 controls the control unit 230 by Bluetooth to operate the tire condition program 232 and limit transmitting the data of the monitoring module 220, the control unit 230 transmits the packet to the transceiver host 100 when the data from the monitoring module 220 compared to the default value of tire condition program 232 shows an abnormal state.

[0022] It is worth mentioning that, in one embodiment, the transceiver host 100 controls the control unit 230 by Bluetooth to operate the locating program 231 first, and then to operate the tire condition program 232 after the operation of the locating program 232 is finished. The order of the processes is as shown in FIG. 3. In another embodiment, the transceiver host 100 controls the control unit 230 via Bluetooth to operate the locating program 231 and the tire condition program 232 simultaneously.

[0027] S104: the Bluetooth tire pressure detector 200 transmits the Bluetooth locating packet to the transceiver host 100;

[0028] S105: the transceiver host 100 receives the Bluetooth locating packet till the locating is finished;

[0029] S106: the transceiver host 100 transmits Bluetooth controlling packet to the Bluetooth tire pressure detector 200 to stop the locating program 231 and start the tire condition program 232;

[0030] S107: the monitoring module 220 of the Bluetooth tire pressure detector 200 detects the tire rotating and generates a Bluetooth tire condition packet; and

[0031] 5108: the Bluetooth tire pressure detector 200 transmits the Bluetooth tire condition packet to the transceiver host 100;

[0032] The above-mentioned transmitting the Bluetooth locating packet to the transceiver host 100 is completed within 10 seconds from the beginning to the end, and the locating program 231 is turned off. The above-mentioned transmitting the Bluetooth tire condition packet to the transceiver host 100 is completed within 3 seconds from the beginning to the end, and contentious the tire condition program 232.

[0033] When the transceiver host 100 controls the control unit 230 by Bluetooth to operate the tire condition program 232 and limit transmitting the data of the monitoring module 220, the control unit 230 transmits the packet to the transceiver host 100 when the data from the monitoring module 220 compared to the default value of the tire condition program 232 shows an abnormal state.

[0034] The Bluetooth tire pressure system of the present disclosure can duplex transmit the packets. According to the needs, the transceiver host 100 controls the Bluetooth tire pressure detector 200 by Bluetooth and operates the tire condition program 231; during this time, the Bluetooth tire pressure detector 200 transmits the Bluetooth locating packet to the transceiver host 100 continuously. When the transceiver host 100 completes the locating of the Bluetooth tire pressure detector 200, the transceiver host 100 transmits a Bluetooth control packet to control the Bluetooth tire pressure detector 200 turning the locating program 231 off and operating the tire condition program 232.

[0035] In conjunction with FIG. 5, which is a method for duplex Bluetooth detecting tire pressure, including:

[0036] S201: starting a vehicle;

[0037] S202: a transceiver host 100 transmits a Bluetooth controls packet to a Bluetooth tire pressure detector 200 to start a locating program 231 and a tire condition program 232;

[0038] S203: the Bluetooth tire pressure detector 200 detects the tire rotating and generates a Bluetooth locating packet and a Bluetooth tire condition packet;

[0040] S205: the transceiver host 100 receives the Bluetooth locating packet till the locating is finished;

[0041] S206: a transceiver host 100 transmits a Bluetooth controlling packet to a Bluetooth tire pressure detector 200 to stop a locating program 231.

[0042] The Bluetooth tire pressure system of the present disclosure can duplex transmit the packets. According to the needs, the transceiver host 100 commands the Bluetooth tire pressure detector 200 by Bluetooth to operate the tire condition program 231 and the tire condition program 232; during this time, the Bluetooth tire pressure detector 200 transmits the Bluetooth locating packet and the Bluetooth tire condition packet to the transceiver host 100 continuously. When the transceiver host 100 completes the locating of the Bluetooth tire pressure detector 200, the transceiver host 100 transmits a Bluetooth control packet to command the Bluetooth tire pressure detector 200 turning the locating program 231 off and keeping operating the tire condition program 232.

[0043] Therefore, the duplex Bluetooth transmission tire pressure system/method of the present disclosure has the following advantages:

[0044] 1. The transceiver host 100 can simultaneously check the data when the Bluetooth locating packet data is received by Bluetooth to ensure whether the Bluetooth locating packet is valid (no errors or interruptions) so that the locating between the Bluetooth tire pressure detector 200 and the transceiver host 100 can be completed in a short time.

[0045] 2. The Bluetooth tire pressure detector 200 can be controlled by the transceiver host 100 to operate the locating program 231 and the tire condition program 232, and after obtaining the locating data of the Bluetooth tire pressure detector 200, the transceiver host 100 transmits a Bluetooth control packet to the Bluetooth tire pressure detector 200 to continuously operate the tire condition program 232. The Bluetooth tire pressure detector 200 only operates and is controlled by the transceiver host 100 when there is a locating requirement, so that the Bluetooth tire pressure detector 200 will not start automatically even when the vehicle temporarily stops and begins again.

[0046] 3. Errors in the locating data of the tire pressure detector can be prevented. In the conventional art, the vehicle must be stopped for a period of time before the tire pressure detector re-transmits the locating data to the transceiver host. At the same time, the present disclosure can transmit the locating data again in a short time.

[0047] 4. Through the above-mentioned operating mechanism, the transceiver host 100 can control the time of the Bluetooth tire pressure detector 200 to operate locating, which saves the time of locating compared with the conventional art; the present disclosure indeed saves the electricity of the Bluetooth tire pressure detector 200 to operate and locate.
