200918354 九、發明說明： 【發明所屬之技術領域】 本發明係有關一種以藍芽無線傳輸之胎壓偵測系統，尤指 一種依序藉由射頻訊號形式及藍芽訊號形式，而將輪胎壓力訊 號於集成後傳遞至電子裝置上並作顯示之系統。 【先前技術】 按，現有之胎壓彳貞測方式，通常係於汽車四個輪胎各裝設 有一訊號擷取裝置，訊號擷取裝置具有感測胎壓之功能，且並 將胎壓以無線之方式傳輸至汽車内儀表板附近之螢幕，此螢幕 係固定設置於汽車中。 因為螢幕通常係於特定位置處作固定式之設置，幾乎沒任 何之移動性’除了拆卸下來’因此，若欲對汽車胎壓之狀態作 觀察時，只得於汽車内觀看，實是不便。且螢幕固定設置於汽 車内時’除了會伯據許多空間，於視覺上亦會覺得汽車内之空 間變的較擁擠，而降低簡潔之美觀性，總之，即是有空間利用 與設計性不佳之缺點。 請參閱美國專利第6 8 2 5 7 5 8號之專利案，其同樣於 汽車四個輪胎上各設置有一訊號擷取裝置，該訊號擷取裝置中 有一感測器、一藍芽訊號發射器與一電池，其中該訊號擷取裝 置中有一可感測輪胎壓力之感測器，所感測到的胎壓訊號可經 k芽訊號發射1發射至手機上，其且該手機必彡貞具備有該公司 所提供之蚊軸方能讀取齡職受到的訊號 ，進而可供使 200918354 用者觀察汽車輪胎之胎壓狀況。 然而’此以手機觀察之技術雖具有可攜觀察之便利優點， 但仍存在一些問題，即因該訊號擷取裝置純粹以藍芽訊號來作 傳輸，因藍芽訊耗電量較高，常會過快耗盡電池之電量，故得 進行更換，然而，若欲直接更換電池亦是不便，因為此類訊號 擷取裝置係設置於輪胎上，若輪胎處於潮濕狀態下，訊號擷取 裝置易受潮而失效，因此訊號擷取裝置即設計成密封之封閉狀 態，以避免受潮失效之問題，故可知，若於直接更換電池幾乎 是不可行的，勢必得直接將整組的訊號擷取裝置作汰換，但如 此，除了支出費用較高外，得較頻繁拆卸輪胎亦是不便。此外， 使用該訊號掘取裝置時，得搭配具特定軟體之手機，如此將侷 限住其可攜之便利性，反而成為缺點。 由上可知，美國專利第6 8 2 5 7 5 8號之專利案雖可適 度克服前習用之不足，但仍然具有如前述之諸問題待解決。 【發明内容】200918354 IX. Description of the Invention: [Technical Field] The present invention relates to a tire pressure detection system for wireless transmission of Bluetooth, in particular, a tire pressure in the form of a radio frequency signal and a Bluetooth signal. The signal is integrated into the electronic device and displayed for display. [Prior Art] According to the existing tire pressure measurement method, usually, four tires are mounted on each of the four tires of the automobile, and the signal extraction device has the function of sensing the tire pressure, and the tire pressure is wireless. The way is transmitted to the screen near the dashboard of the car, which is fixed in the car. Since the screen is usually fixed at a specific position, there is almost no mobility except for disassembly. Therefore, if the state of the tire pressure is to be observed, it is inconvenient to watch in the car. When the screen is fixed in the car, in addition to the space, it will visually feel that the space inside the car becomes more crowded, and the simplicity of the appearance is reduced. In short, there is space utilization and poor design. Disadvantages. Please refer to the patent of US Pat. No. 6, 8 2 5 7 8 8 , which is also provided with a signal extraction device on each of the four tires of the automobile. The signal extraction device has a sensor and a blue signal transmitter. And a battery, wherein the signal extracting device has a sensor for sensing tire pressure, and the sensed tire pressure signal can be transmitted to the mobile phone via the k-ray signal transmission 1, and the mobile phone must have The mosquito shaft provided by the company can read the signals received by the aged, so that the users of 200918354 can observe the tire pressure of the automobile tires. However, although the technology of mobile phone observation has the advantage of portable observation, there are still some problems. Because the signal acquisition device is purely transmitted by Bluetooth signal, the power consumption of Bluetooth signal is high. It is too fast to drain the battery, so it has to be replaced. However, it is inconvenient to replace the battery directly, because such a signal extraction device is placed on the tire, and if the tire is in a wet state, the signal extraction device is susceptible to moisture. However, the signal extraction device is designed to be sealed and sealed to avoid the problem of moisture failure. Therefore, if it is almost impossible to replace the battery directly, it is necessary to directly remove the entire signal extraction device. Change, but in this case, in addition to higher expenditures, it is inconvenient to disassemble tires more frequently. In addition, when using the signal to dig the device, it is necessary to use a mobile phone with a specific software, which will limit its portability and become a disadvantage. It can be seen from the above that although the patent of U.S. Patent No. 6, 8 2 5 7 8 can reasonably overcome the disadvantages of the prior application, it still has the problems as described above to be solved.

In addition, the above-mentioned 5 ray sensor 1 1 can be further used to sense the temperature in the tire 21 and display the temperature signal to the user in a manner that the temperature signal is transmitted to the electronic device 4 by the same tire pressure signal. That is, the temperature signal of the tire is transmitted to the micro control unit 12, processed by the micro control unit 12, and transmitted to the radio frequency transmitter 13 and the temperature signal is transmitted by the radio frequency signal, and the signal is transmitted by the signal. The receiving host 3 receives the temperature signal, and processes the temperature signals from the four tires into an integrated temperature signal, and then transmits the integrated temperature signal in the form of a blue signal, and then receives the integrated temperature signal by the electronic device 4. It is not visible on the screen 41, and the user can understand the temperature condition of the four tires. Referring to Fig. 3, in the embodiment, the signal extracting device is further connected with an inflating head 5 passing through the rim 22 of the tire 21. In use, the tire pressure detecting system can play the following role. When the user wants to know the actual condition of the tire pressure of the automobile tire, the user only needs to use the electronic device 4 having the function of receiving the Bluetooth signal, such as A mobile phone, a pda, a gps 200918354, a notebook computer, or the like is equipped with a device such as a screen 41, and receives a tire pressure and a temperature § fi from a plurality of tires 21 by a signal receiving host 3 positioned in a relay role.
