Tire detection data transmission system and the setting method thereof

Abstract

A tire detection data transmission system and the setting method thereof include at least one monitoring device, for detecting the condition of vehicle tires and generating tire information, which is transmitted via a RF signal to a transfer device. The transfer device then uses a Bluetooth signal to transmit the received tire information to a mobile communication device. The RF signal emitted by the monitoring device includes at least the tire information and the identification code of the monitoring device. The identification code makes subsequent updates to the settings of the monitoring device simpler and more convenient.

What is claimed is:  
     
         1 . A tire detection data transmission system, comprising:

         2 . The tire detection data transmission system of  claim 1 , wherein the CPU has an RF decoding unit, a data holding unit, and a data integration unit; the RF decoding unit decodes the RF signal received by the RF receiver, restores the RF signal into the tire information and the corresponding ID code in a specific coding and stores the tire information and the ID code in the data holding unit; the data holding unit holds multiple sets of tire information and is overwritable, keeping only the last tire information according to the coding; and the data integration unit collects the multiple sets of tire information in the data holding unit into the collective data and outputs the collective data to the BT module. 
     
     
         3 . The tire detection data transmission system of  claim 2 , wherein the CPU further has a tire condition judging unit and an alarm unit, the tire condition judging unit is preset with a default value to be compared with the tire information in the data holding unit, when the tire information exceeds the range of the default value the tire condition judging unit transmits an alarm signal to the alarm unit for the alarm unit to perform an alarm action. 
     
     
         4 . The tire detection data transmission system of  claim 1 , wherein the transfer device uses the BT module thereof to emit a BT pairing message, the BT device of the mobile communication device receives the BT pairing message and generates a corresponding data transmission command to complete the pairing. 
     
     
         5 . The tire detection data transmission system of  claim 4 , wherein the BT module has a BT converter and a BT emitter, the BT converts converting the received collective data into a BT signal and the BT emitter emitting the BT signal to the paired mobile communication device. 
     
     
         6 . The tire detection data transmission system of  claim 1 , wherein the executable software contains a receiving program, an analyzing program, and a displaying program, the receiving program receives the collective data restored by the BT device, the analyzing program breaks the collective data into multiple sets of tire information and the corresponding ID codes, the displaying program shows the tire information and the corresponding ID code in the corresponding displaying block of the display unit, and only the last set of tire information is displayed according to the coding. 
     
     
         7 . The tire detection data transmission system of  claim 6 , wherein the executable software further has a trigger program for generating a data reading command to the BT device. 
     
     
         8 . The tire detection data transmission system of  claim 7 , wherein the display unit is a touch-controls screen, the displaying program shows a touch-control display interface on the display unit, and touch-control display interface has a graphical interface for each of the tires for the user to click for starting the trigger program to show the tire information of the corresponding tire therein. 
     
     
         9 . A setting method of the tire detection data transmission system according to  claim 1 , comprising the steps of:
 a. starting the executable software;   b. displaying a graphical interface for each of the tires on the display unit, each of the graphical interfaces including a mode setting option;   c. selecting the mode setting option and entering an ID code for the newly replaced monitoring device, thereby updating the ID code of the monitoring device for the corresponding tire in the executable software; and   d. transmitting an update message from the executable software to the transfer device via the BT device to update the ID code of the monitoring device for the corresponding tire in the transfer device.   
     
     
         10 . The setting method of  claim 9  with the mode setting option being able to modify the communication protocol of the monitoring device, comprising the steps of:
