Description
本發明係關於一種胎壓偵測裝置，尤其是關於具有載波偵測功能的胎壓偵測裝置。The invention relates to a tire pressure detecting device, in particular to a tire pressure detecting device with a carrier detecting function.
請參考第五圖，其為目前既有的胎壓偵測器的安裝即使用方式示意圖，目前的胎壓偵測器(51)可安裝於一汽車(50)的輪胎(52)上，實際應用上，通常於汽車(50)每個輪胎(52)均安裝一個該胎壓偵測器(51)。該胎壓偵測器(51)以無線訊號將檢測結果傳送給安裝於該汽車(50)內之一監測裝置(53)，該監測裝置(53)包含接收單元、通訊介面與顯示單元，且接受各胎壓偵測器(51)所傳送之無線訊號，並持續將各胎壓偵測器(51)之檢測結果透過顯示單元或傳送至該汽車(50)之儀表板，隨時警示及通報汽車駕駛。每一個胎壓偵測器(51)在出廠時，都會內建配有一組編號(ID)，當該胎壓偵測器(51)傳送訊號時，常一併傳送該編號，以供該監測裝置(53)識別各個胎壓偵測器(51)所傳送的訊號，也可避免其他鄰近車輛的胎壓偵測器(51)所傳送的訊號遭到該監測裝置(53)誤用。Please refer to the fifth figure, which is a schematic diagram of the installation and use mode of the existing tire pressure detector. The current tire pressure detector (51) can be mounted on the tire (52) of a car (50). In application, one of the tire pressure detectors (51) is usually installed in each tire (52) of the automobile (50). The tire pressure detector (51) transmits the detection result to a monitoring device (53) installed in the automobile (50) by using a wireless signal, and the monitoring device (53) comprises a receiving unit, a communication interface and a display unit, and Receiving the wireless signals transmitted by the tire pressure detectors (51), and continuously transmitting the detection results of the tire pressure detectors (51) through the display unit or to the dashboard of the automobile (50) for warning and notification at any time. Car driving. Each tire pressure detector (51) is built-in with a set of numbers (ID). When the tire pressure detector (51) transmits a signal, the number is often transmitted for monitoring. The device (53) identifies the signals transmitted by the respective tire pressure detectors (51), and also prevents the signals transmitted by the tire pressure detectors (51) of other adjacent vehicles from being misused by the monitoring device (53).
然而，前述該監測裝置(53)及各胎壓偵測器(51)之間的訊號傳遞方式屬於單向通訊，每一胎壓偵測器(51)無從得知其他的胎壓偵測器(51)是否正在傳送資料，因此，很容易讓兩個或兩個以上的胎壓偵測器(51)同時發送無線訊號給該監測裝置(53)，如此，各胎壓偵測器(51)所傳送的 無線訊號可能相互干擾、衝突而導致資料內容失真，造成資料傳送失敗。However, the signal transmission mode between the monitoring device (53) and each tire pressure detector (51) belongs to one-way communication, and each tire pressure detector (51) has no other tire pressure detector. (51) Whether data is being transmitted, so it is easy for two or more tire pressure detectors (51) to simultaneously send wireless signals to the monitoring device (53), thus, each tire pressure detector (51) Transmitted Wireless signals may interfere with each other and cause conflicts in the data content, causing data transmission failure.
為了克服前述因為同時傳送造成資料衝突的問題，一美國核准公告第6,486,773號專利案係使每一胎壓偵測器(51)每次傳送資料均會同時傳送8筆資料，且讓每筆資料傳送後都延遲一段時間之後才繼續發送資料，以解決資料相互干擾的問題。顯然地，US6486773專利所提出的方法雖可以解決資料衝突的問題，但其對於胎壓偵測器(51)之電力消耗非常嚴重，造成該胎壓偵測器使用壽命縮短。In order to overcome the above-mentioned problem of data conflict caused by simultaneous transmission, a patent approved by US U.S. Patent No. 6,486,773 causes each tire pressure detector (51) to transmit 8 pieces of data at a time, and each piece of data is transmitted. After the transmission is delayed for a while, the data will continue to be sent to solve the problem of data interference. Obviously, the method proposed in the US Pat. No. 6,486,773 patent can solve the problem of data conflict, but the power consumption of the tire pressure detector (51) is very serious, resulting in shortened service life of the tire pressure detector.
另外，尚有一美國核准公告第7,253,726號專利案，其係於每一胎壓偵測器內部安裝一低頻接收電路，同時在每一個胎壓偵測器必須配合一個低頻喚醒裝置，各低頻喚醒裝置接受控制於不同時間區間內喚醒其鄰近對應的胎壓偵測器進行訊號傳遞，以避免各胎壓偵測器於同時間傳送訊號的問題。然而，依據此一方式雖可以解決前述問題，但是，卻必須額外增加四個低頻喚醒裝置，造成成本增加。In addition, there is a U.S. approved publication No. 7,253,726, which is equipped with a low frequency receiving circuit inside each tire pressure detector, and a low frequency wake-up device, each low frequency wake-up device in each tire pressure detector. It is controlled to wake up the adjacent tire pressure detectors for signal transmission in different time intervals to avoid the problem that the tire pressure detectors transmit signals at the same time. However, although the foregoing problem can be solved according to this method, it is necessary to additionally add four low frequency wake-up devices, resulting in an increase in cost.
為了解決目前的胎壓偵測器單向資訊傳遞容易發生資料衝突、多次訊號傳送造成電力耗損或需要額外增加喚醒裝置等諸多問題，本發明係讓每一胎壓偵測器可以自行偵測鄰近之載波，並於鄰近位置不存在載波時才進行訊號傳遞，以避免無線訊號相互衝突的問題，同時解決成本、電力大量損耗等諸多問題。In order to solve the problems that the current one-way information transmission of the tire pressure detector is prone to data collision, power loss caused by multiple signal transmissions, or additional wake-up device, the present invention allows each tire pressure detector to detect itself. The adjacent carrier and the signal transmission are performed when there is no carrier in the adjacent position, so as to avoid the problem that the wireless signals collide with each other, and solve the problems of cost, power loss and the like.

該高頻傳送介面(162)為接受該微處理控制模組(12)控制將該感測結果以一高頻無線訊號傳遞給該監測裝置，其可為包含天線之無線傳輸電路。The high frequency transmission interface (162) is controlled by the microprocessor control module (12) to transmit the sensing result to the monitoring device as a high frequency wireless signal, which may be a wireless transmission circuit including an antenna.
該載波感應介面(164)則為與該高頻無線訊號相對應、可感應與該高頻無線訊號具有相同頻率之無線訊號(可為內 含資料的無線訊號或者為單純的載波)之感應線圈或電路，其可感應其鄰近位置空間之該高頻無線訊號，並於感應後，產生感應電壓、感應電流或數位訊號輸出，微處理控制模組(12)針對不同的訊號源訊，可透過類比轉數位的介面來處理類比的電壓、電流訊號或直接讀取數位訊號。與該高頻無線訊號具有相同頻率之無線訊號，可為由其他之可偵測載波之胎壓偵測裝置(10，10A，10B)所傳送之該高頻無線訊號，或為由其他一般之胎壓偵測器所傳送之無線訊號，其中，無線訊號之頻率與該高頻無線訊號相對應或相同。The carrier sensing interface (164) is a wireless signal corresponding to the high frequency wireless signal and capable of sensing the same frequency as the high frequency wireless signal (may be internal) Inductive coil or circuit containing data wireless signal or simple carrier, which can sense the high frequency wireless signal in the adjacent position space, and generate induced voltage, induced current or digital signal output after induction, micro processing control The module (12) can process the analog voltage, current signal or directly read the digital signal through the analog-to-digital interface for different signal sources.

該高頻接收介面(164A)則為一具有天線的電路，其可接收該高頻無線訊號，並將所接收的高頻無線訊號給該微處理控制模組(12)。The high frequency receiving interface (164A) is a circuit having an antenna that receives the high frequency wireless signal and sends the received high frequency wireless signal to the microprocessor control module (12).
如第三圖所示，該傳送感應模組(16)也可由一高頻傳送接收介面(17)取代，其係為包含天線且可以進行該高頻無線訊號之傳送及接收之電路單元，該高頻傳送接收介面(17)係於沒有在進行傳送該高頻無線訊號的時間內，接受該微處理控制模組(12)之控制進行該高頻無線訊號之接收，並將接收之結果輸出至該微處理控制模組(12)。As shown in the third figure, the transmission sensing module (16) can also be replaced by a high frequency transmission receiving interface (17), which is a circuit unit including an antenna and capable of transmitting and receiving the high frequency wireless signal. The high frequency transmission receiving interface (17) is controlled by the microprocessor control module (12) to receive the high frequency wireless signal without receiving the high frequency wireless signal, and outputs the received result. To the microprocessor control module (12).
其中，該傳送感應模組(16)或該高頻傳送接收介面(17)所傳送或接收之該高頻無線訊號之頻率可介於UHF頻段之等級，例如315MHz、433MHz、455MHz...等。The frequency of the high frequency wireless signal transmitted or received by the transmission sensing module (16) or the high frequency transmission receiving interface (17) may be in the UHF frequency band, for example, 315 MHz, 433 MHz, 455 MHz, etc. .
該電力模組(18)則提供該可偵測載波之胎壓偵測裝置(10，10A，10B)之內部其他功能模組操作所需之電力，其 可為一電池或電能搜集系統。The power module (18) provides power required for operation of other internal functional modules of the detectable carrier tire pressure detecting device (10, 10A, 10B). Can be a battery or power collection system.
該低頻接收模組(19)為一可接受外部訊號線連接之連接器或為一低頻無線接收器，例如125kHz...等。本較佳實施例之該低頻接收模組(19)接受該微處理控制模組(12)之控制，接受外部之一低頻無線訊號，該低頻無線訊號之頻率相對低於該傳送感應模組(16)之高頻無線訊號。The low frequency receiving module (19) is a connector that can accept an external signal line connection or a low frequency wireless receiver, such as 125 kHz...etc. The low frequency receiving module (19) of the preferred embodiment is controlled by the microprocessor control module (12) to receive an external low frequency wireless signal, and the frequency of the low frequency wireless signal is relatively lower than the transmitting sensing module ( 16) High frequency wireless signal.
由於低頻訊號的穿透率較差，故訊號接受距離受到限制，所以若欲以該低頻接收模組(19)讀取接收外部無線訊號，則該低頻接收模組(19)必須相當程度地接近外部無線訊號源。故於使用時，該可偵測載波之胎壓偵測裝置(10，10A，10B)可利用該低頻接收模組(19)接近不同的外部無線訊號源，而分別讀取不同的外部無線訊號源。當外部無線訊號源或該低頻無線訊號為包含一編號之一編號寫入指令時，該微處理控制模組(12)則讀入該編號寫入訊號之編號，並將該編號寫入該記憶單元(122)內。如此，使該可偵測載波之胎壓偵測裝置(10，10A，10B)可以更新、拷貝或替換其編號，讓該可偵測載波之胎壓偵測裝置(10，10A，10B)於編號被替換或取代之後，直接與其他之監測裝置進行連線及訊號傳遞。Since the penetration rate of the low frequency signal is poor, the signal receiving distance is limited, so if the low frequency receiving module (19) is to read and receive the external wireless signal, the low frequency receiving module (19) must be relatively close to the outside. Wireless signal source. Therefore, when used, the detectable carrier tire pressure detecting device (10, 10A, 10B) can use the low frequency receiving module (19) to access different external wireless signal sources, and respectively read different external wireless signals. source. When the external wireless signal source or the low frequency wireless signal is a number one written command, the microprocessor control module (12) reads the number of the numbered signal and writes the number to the memory. Within unit (122). In this way, the tire pressure detecting device (10, 10A, 10B) of the detectable carrier can update, copy or replace the number, so that the tire pressure detecting device (10, 10A, 10B) of the detectable carrier is After the number is replaced or replaced, it is directly connected to other monitoring devices for signal and signal transmission.
由於目前的監測裝置必須經過冗長的設定方式，才可與一個新的胎壓偵測器進行訊號傳遞，其原因在於各胎壓偵測器的編號不同所致，因此，本較佳實施例可以拷貝已經可以與該監測裝置進行訊號傳遞的胎壓偵測器之編號，於編號拷貝之後直接取代舊有的胎壓偵測器。Since the current monitoring device has to undergo a lengthy setting, the signal transmission can be performed with a new tire pressure detector because the number of each tire pressure detector is different. Therefore, the preferred embodiment can The number of the tire pressure detector that can be used to transmit signals to the monitoring device is copied, and the old tire pressure detector is directly replaced after the number copy.
使用時，可將四個該可偵測載波之胎壓偵測裝置(10，10A，10B)分別安裝於汽車之四個輪胎內，分別感測每個輪胎的內部狀態訊號，並輸出該高頻無線訊號傳送給該監測裝置。當每一可偵測載波之胎壓偵測裝置(10，10A，10B)透過該載波感應介面(164)或該高頻接收介面(164A)或該高頻傳送接收介面(17)接收或感應外部之該高頻無線訊號時，則接受該微處理控制模組(12)控制，暫時不傳送感應之結果；反之，若該可偵測載波之胎壓偵測裝置(10，10A，10B)之該微處理控制模組(12)並沒有於該載波感應介面(164)或該高頻接收介面(164A)或該高頻傳送接收介面(17)感應或接收外部之該高頻無線訊號，該微處理控制模組(12)則透過該高頻傳送介面(162)或該高頻傳送接收介面(17)傳遞其對應之該胎內狀況感應模組(14)的感測結果形成一個該高頻無線訊號予以傳送給該監測裝置。如此，每一個該可偵測載波之胎壓偵測裝置(10，10A，10B)僅在鄰近環境不存在其他之可偵測載波之胎壓偵測裝置(10，10A，10B)所傳送之該高頻無線訊號時，才進行高頻無線訊號之傳送，因此，可避免先前技術資料衝突的問題。另外，即使採用本較佳實施例的汽車行駛於車陣之中，由於法規之限制，其他汽車之胎壓偵測器的發射時間及功率受限，所以頻段不會一直被佔住，且限制發射的功率則限制發射距離，故車輛之間的胎壓偵測器之載波接收之相互影響狀況相當的低。In use, four tire pressure detecting devices (10, 10A, 10B) of the detectable carrier can be respectively installed in the four tires of the automobile, respectively sensing the internal state signals of each tire, and outputting the high The frequency wireless signal is transmitted to the monitoring device. When each detectable carrier tire pressure detecting device (10, 10A, 10B) receives or senses through the carrier sensing interface (164) or the high frequency receiving interface (164A) or the high frequency transmitting receiving interface (17) When the external high frequency wireless signal is received, the microprocessor control module (12) is controlled to temporarily not transmit the result of the sensing; otherwise, if the detectable carrier tire pressure detecting device (10, 10A, 10B) The microprocessor control module (12) does not sense or receive the external high frequency wireless signal from the carrier sensing interface (164) or the high frequency receiving interface (164A) or the high frequency transmitting and receiving interface (17). The microprocessor control module (12) transmits the corresponding sensing result of the intra-fetal condition sensing module (14) through the high-frequency transmission interface (162) or the high-frequency transmission receiving interface (17) to form a The high frequency wireless signal is transmitted to the monitoring device. Thus, each of the detectable carrier tire pressure detecting devices (10, 10A, 10B) is transmitted only by the tire pressure detecting device (10, 10A, 10B) in the vicinity of which there is no other detectable carrier. When the high-frequency wireless signal is transmitted, the transmission of the high-frequency wireless signal is performed, so that the problem of conflicting prior art data can be avoided. In addition, even if the automobile of the preferred embodiment is used in a vehicle array, the transmission time and power of other automobile tire pressure detectors are limited due to regulatory restrictions, so the frequency band is not always occupied and limited. The transmitted power limits the transmission distance, so the mutual influence of the carrier reception of the tire pressure detector between vehicles is relatively low.
請參考第四圖，其為本發明之胎壓偵測裝置之載波偵 測方法的較佳實施例，其步驟包含：啟動(41)、偵測胎內狀態(42)、判斷是否已達傳送時間(43)、判斷是否已偵測載波訊號(44)、資料傳送(45)以及進入休眠狀態(46)。Please refer to the fourth figure, which is the carrier detect of the tire pressure detecting device of the present invention. In a preferred embodiment of the method, the steps include: starting (41), detecting the intra-fetal state (42), determining whether the transmission time has been reached (43), determining whether the carrier signal (44) has been detected, and transmitting data ( 45) and enter the sleep state (46).
該啟動(41)步驟，係為開啟該胎壓偵測裝置，使該胎壓偵測裝置離開一休眠狀態。The step (41) is to turn on the tire pressure detecting device to cause the tire pressure detecting device to leave a sleep state.
該偵測胎內狀態(42)步驟，係該胎壓偵測裝置感測其對應輪胎內的胎壓、溫度...等狀態訊號。The step of detecting the in-cylinder state (42) is that the tire pressure detecting device senses a state signal such as a tire pressure, a temperature, and the like in the corresponding tire.
該判斷是否已達傳送時間(43)步驟，所謂之傳送時間，係為該胎壓偵測裝置事先內部設定的一時間區間，例如60秒、120秒...等，該胎壓偵測裝置於每一時間區間內量測一次輪胎內的狀態訊號並予以傳送。當本步驟(43)之判斷結果為是，則進行下一步驟，反之，則重複進行本步驟(43)。Whether the determination has reached the transmission time (43) step, the so-called transmission time is a time interval internally set by the tire pressure detecting device, for example, 60 seconds, 120 seconds, etc., the tire pressure detecting device The status signal in the tire is measured and transmitted in each time interval. When the judgment result in the step (43) is YES, the next step is performed, otherwise, the step (43) is repeated.
該判斷是否已偵測載波訊號(44)步驟，係該胎壓偵測裝置以感應或無線接收的方式，讀取其鄰近範圍內是否存在一載波訊號，所謂之載波訊號係代表其他的胎壓偵測裝置所傳送之無線訊號；當判斷結果係該胎壓偵測裝置並感應到外部環境存在該載波訊號，則進行一延遲(442)步驟，反之，則進行下一步驟(45)。The step of determining whether the carrier signal (44) has been detected is that the tire pressure detecting device reads whether there is a carrier signal in the proximity range by means of induction or wireless reception, and the so-called carrier signal represents other tire pressure Detecting the wireless signal transmitted by the device; when the result of the determination is that the tire pressure detecting device senses that the carrier signal exists in the external environment, performing a delay (442) step, and vice versa, proceeding to the next step (45).
該延遲(442)步驟，係該胎壓偵測裝置進行一延遲倒數時間，並於該延遲倒數時間內進入省電模式，不進行動作及防止消耗電能，且於該延遲(442)步驟完成後，重新回到該步驟(44)。The delay (442) step is that the tire pressure detecting device performs a delay countdown time, enters the power saving mode within the delay countdown time, does not operate and prevents power consumption, and after the delay (442) step is completed , go back to this step (44).
該資料傳送(45)步驟，係該胎壓偵測裝置將其感測的狀態訊號產生一個無線之載波訊號予以傳送。The data transmission (45) step is that the tire pressure detecting device generates a wireless carrier signal by transmitting the sensed status signal.
該進入休眠狀態(46)步驟，係該胎壓偵測裝置進入一相對較為省電之休眠狀態。The step of entering the sleep state (46) is that the tire pressure detecting device enters a relatively power-saving sleep state.
