the transmitted signal is sensed tire condition means the corresponding position. 本发明可应用于如图1所示的轮胎监测系统,以下仅使用图1来简单说明本发明的轮胎状态感测装置的定位方法。 The present invention can be applied to a tire monitoring system shown in Figure 1, 1 will be briefly described below using FIG positioning method only tire condition sensing device according to the present invention. 然而,本发明并不仅仅限于此例,本发明可应用于具有任意数目轮胎(包括备胎)的任何运输工具(如汽车、机车等)。 However, the present invention is not limited to this embodiment, the present invention is applicable to any vehicle with any number of tires (including the spare) (e.g., automobile, motorcycle, etc.). 参照图1和图2,图2为本发明实施例的轮胎状态感测装置的定位方法的信号示意图,其中轮胎状态感测装置12、 14、 16和18轮流每隔第一时间长度的时间(例如:l分钟)持续地发射第二时间长度的信号(例如:10ms)之久。 Referring to FIG. 1 and FIG. 2, FIG. 2 is a schematic view of the positioning signal of a tire condition sensing method of an embodiment of the apparatus of the invention, wherein 12, 14, 16 and 18 turns every time a first time length of the tire condition sensing means ( For example: 10ms) long: l min) signal (e.g., length of the second duration transmitted. 如图2所示,在时间点t0时,首先,发现轮胎状态感测装置正在发射信号。 As shown in FIG. 2, at time point t0, first, the found tire condition sensing apparatus is transmitting signals. 然后,轮胎监测系统进入一定位模式。 Then, tire monitoring system enters a positioning mode. 在时间点to至时间点tl之间(简称为第三时间长度),天线22、 24、 26和28接收到关于某一轮胎的状况的信号,将此信号传到接收器30后,将此信号译码。 At the time point to to (referred to as a length of the third time) between time point tl, the antenna 22, and 28 receives the status signal about a tire 24, 26, this signal is transmitted to the receiver 30, this signal decoding. 由于此信号包括有轮胎状态感测装置的识别编号,故由此识别编号可知此信号是从例如轮胎状态感测装置14所发射。 Because of this identification number signal includes a tire condition sensing device, whereby it is seen that this identification number is transmitted from the signal 14, for example, a tire condition sensing apparatus. 然而,由于此时系统不知道轮胎状态感测装置14是位于那一个轮胎,故系统无法得知此信号是关于那一个轮胎的状况。 However, since the system does not know at this time the tire condition sensing apparatus 14 that is located in a tire, so that the system can not know about this situation is that a signal of the tire. 接着,系统会判断此信号是否在时间点t0至时间点tl之间持续被发射,即信号是否在这段时间中持续被接收器30所收到,若判断结果为是, 则取得天线22、 24、 26和28共同接收此信号后由接收器30所产生的第一信号强度(如t0至tl间的信号曲线70的信号强度平均值)。 Next, the system determines whether the signal at a time point between the time point t0 to tl is transmitted continuously, i.e., during which time signal is continuously received by the receiver 30, if the judgment result is YES, the antenna 22 to obtain, first signal strength after 24, 26 and 28 commonly receive the signal generated by the receiver 30 (e.g., signal curve between t0 and tl the signal strength average value of 70). 然后,判断前面所述的识别编号是否属于系统(即是否由系统所在的运输工具中的轮胎状态感测装置所发射出来)。 Then, the foregoing is determined whether the identification number of the system (i.e., whether or not the vehicle emitted by the system is located in the tire condition sensing device). 若识别编号是属于系统,则进行识别信号位置的步骤。 If the identification code is part of the system, the step of identifying the position signal is performed. 在时间点tl时,将天线22、 24、 26和28全部关闭,再轮流快速地先开后关每一个天线,并使每一个天线的启动状态均持续地维持一段时间(例如:0.44ms)。 At time point tl, the antenna 22, 24, 26 and 28 are all closed, and then quickly turn the first switching each antenna, and each antenna are continuously activated state for some time (e.g.: 0.44ms) . 例如:将天线22、 24、 26和28全部关闭后, 在时间点tl开启天线22,再在时间点t2关闭天线22并开启天线24;再在时间点t3关闭天线24并开启天线26;再在时间点t4关闭天线26并开启天线28;然后,在时间点t5全部开启天线22、 24、 26和28,其中时间点tl、 t2、 t3、 t4和t5的间隔例如为:0.44ms (简称为第四时间长度)。 For example: After the antenna 22, 24, 26 and 28 are all closed, at the time point tl turned antenna 22, then at the time point t2 to close the antenna 22 and turn the antenna 24; then close the antenna 24 at the time point t3 and turned antenna 26; then off at the time point t4 turn the antenna 28 and the antenna 26; then, at the time point t5 all open antennas 22, 24, 26 and 28, wherein the time point tl, t2, t3, t4 and t5 intervals, for example: 0.44ms (referred to as a fourth length of time). 当快速地轮流开关天线22、 24、 26和28时,信号曲线70的第一信号强度会随之变化为信号曲线72、 74、 76和78的多个第二信号强度,比较第一信号强度和第二信号强度后,可获得的多个信号强度变化值(差值)。 When 22, 24, 26 and 28, the signal strength of curve 70 of the first signal will change with signal curve 72, 74, 76 and 78 of the plurality of second signal strength, comparing the first signal strength of the antenna switch rapidly turns and the second signal strength, the signal strength of the plurality of change values ​​obtained (difference). 接着,比较这些信号强度变化值,而得一最大值,即信号曲线74,而信号曲线74系在开关天线24时所产生,即代表天线24最靠近正在发射信号的轮胎状态感测装置。 Next, comparing the change in signal strength value, a maximum value is obtained, i.e. the signal curve 74, curve 74 and the signal line generated when the antenna switch 24, which represents the antenna 24 is closest to the tire condition sensing means transmitting a signal. 由于此轮胎状态感测装置必定具有前面所述的识别编号,而此识别编号是属于轮胎状态感测装置14,故系统可识别出轮胎状态感测装置14的位置系对应于天线24,即轮胎状态感测装置14是检测天线24所对应的轮胎。 Because of this tire condition sensing apparatus has an identification number must be previously described, and this identification number is part of the tire condition sensing device 14, so that the system can recognize the position of the tire condition sensing system 14 corresponding to the antenna device 24, i.e., the tire condition sensing device 14 is a detection antenna 24 of corresponding tire. 然后,在时间点t5之后,系统会分别接收到轮胎状态感测装置12、 16和18所发射的信号,重复上述步骤后,系统便可分别识别出所有轮胎状态感测装置12、 16和18的位置。 Then, after the time point T5, the system receives the tire condition sensing device 12, respectively, the transmitted signal 16 and 18, after repeating the above steps, respectively, the system can identify all of the tire condition sensing means 12, 16 and 18 s position. 值得一提的是,假如轮胎状态感测装置每隔1分钟持续地发射信号10ms,因此,本发明的辨识一个轮胎状态感测装置的操作时间(如时间点t0至t5)必须在10ms中完成。 It is worth mentioning that one minute continuously transmit signals 10ms if every tire condition sensing apparatus, therefore, the present invention is a recognition operation time (e.g., time point t0 to t5) of the tire condition sensing device must be done in 10ms . 因而,本发明所使用的信号接收电路必须能在10ms内反应出天线影响信号强度的变化值。 Thus, the signal receiving circuit used in the present invention must be able to reflect the influence of the antenna signal strength variation within 10ms. 另外,其中本发明所使用的天线可为同一规格型号的天线。 Further, where the antenna used in the present invention may be of the same specification type antenna. 另外,本发明实施例的辨识识别信号位置的步骤亦可在时间点tl时, 维持天线22、 24、 26和28于启动状态,再轮流快速地先关后开每一个天线,并使每一个天线的关闭状态均持续地维持一段时间(例如:0.44ms)。 Further, the step of identifying the position of the identification signal to an embodiment of the present invention may also be at a time point tl, to maintain the antenna 22, 24, 26 and 28 in each active state, then quickly turn to open after the first turn of each antenna, and closed state of the antenna are continuously maintained for a period of time (e.g.: 0.44ms). 例如:在时间点tl关闭天线22,再在时间点t2开启天线22并关闭天线24;再在时间点t3开启天线24并关闭天线26;再在时间点t4开启天线26并关闭天线28;然后,在时间点t5全部开启天线28 。 For example: at a time point tl off the antenna 22, again at a time point t2 turn antenna 22 and close the antenna 24; reopening antenna 24 at the time point t3 and close the antenna 26; reopening antenna 26 at the time point t4 and close the antenna 28; and at time t5 fully open antenna 28. 当快速地轮流关开天线22、 24、 26和28时,信号曲线70的信号强度会随之减弱,而分别产生第二信号强度,并获得第一信号强度与第二信号强度间的多个信号强度变化值(差值)。 Quickly turns OFF when the antenna 22, 24, 26 and 28, the signal intensity profile signal 70 will weakens, and generate a second signal strength, and received between the plurality of first signal strength and the second signal strength change in signal intensity value (difference). 接着,比较这些信号强度变化值,以找出哪一个变化最大(减少最多),便可得知产生最大变化值的天线所对应的轮胎, 就是正在发射信号的轮胎状态感测装置的所在位置。 Location tire condition sensing device then comparing the change in signal strength values, to find out which changes a maximum (largest reduction), that the antenna can generate a maximum change value corresponding to the tire, the signal is being transmitted. 参照图3A和图3B,分别为本发明实施例的轮胎状态感测装置的定位方法和识别信号位置步骤的流程示意图。 3A and 3B, a method of locating the tire condition sensing apparatus of the embodiment schematic flow chart of the position signal and the identification step of the present invention respectively. 如图3A所示,首先,进行步骤100以提供多个天线,其中这些天线分别安装在靠近多个轮胎状态感测装态感测装置则安装在一运输工具中。 3A, the first step 100 to provide a plurality of antennas, wherein the plurality of antennas are mounted adjacent the tire condition sensing apparatus state sensing means is mounted in a means of transport. 在轮胎监测系统进入定位模式(步骤110)后,将天线全部启动(步骤120)。 After the tire monitoring system to enter the positioning mode (step 110), all the antenna started (step 120). 接着,进行步骤130以接收并译码一信号,其中此信号至少包括有一识别编号,而此识别编号属于轮胎状态感测装置中的第一轮胎状态感测装置,故此信号是由第一轮胎状态感测装置所发射。 Next, step 130 receives and decodes a signal, wherein the signal comprises at least an identification number, and this identification number belonging to the first tire condition sensing device tire condition sensing device, and therefore the first signal is a state of the tire sensing means transmitted. 然后,进行步骤140判断是否持续发射信号,即此信号是否在一段时间中持续被发射。 Then, step 140 determines whether or not continuous transmission signal, i.e. whether the signal is transmitted continuously over a period of time. 若步骤140的结果为是, 则取得天线共同接收信号(接收器所获得的信号)后所产生的信号强度(步骤150)。 If the result of step 140 is YES, then the signal strength to obtain a common antenna reception signal (a signal obtained by the receiver) is generated (step 150). 进行步骤160以判断信号的识别编号是否属于此运输工具。 Step 160 determines whether the identification number signal of this vehicle. 若步骤160的结果为是,则进行辨识信号位置的步骤170。 If the result of step 160 is YES, a step position identification signal 170 is performed. 若步骤140或步骤160的结果为否,则回到步骤130以继续接收并译码一信号。 If the outcome of step 140 or step 160 is NO, the process returns to step 130 to continue to receive and decode a signal. 如图3B所示,在识别信号位置的步骤170中,首先,轮流快速地开关每一个天线(步骤172),接收器接收此信号后产生多个信号强度变化值,其中每一个天线的启动状态或关闭状态均持续地维持在一段时间中。 3B, the position of the identification signal in step 170, firstly, in turn generating a plurality of switching rapidly change in signal intensity value for each antenna (step 172), the receiver receives the signal, wherein the start-up state of each antenna or off state are continuously maintained in a period of time. 如上所述,在进行识别信号位置的步骤170之前,可先将天线全部关闭, 再轮流快速地先开后关每一个天线,其中每一个天线的启动状态均持续地维持一段时间;或者,在进行识别信号位置的步骤之前,仍旧保持全部天线于启动状态,再轮流快速地先关后开每一个天线,其中每一个天线的关闭状态均持续地维持一段时间。 As described above, performing the step of identifying the position signal 170 before, first antenna may be all closed, and then to turn off quickly after opening each antenna, wherein each antenna are continuously activated state for some time; or, in prior to the step of identifying the location of a signal, still remains in the active state all the antennas, and then turns off the first fast-open each antenna, wherein each antenna of the closed state are continuously maintained for some time. 接着,进行步骤174以比较这些信号强度变化值,而得一最大值。 Next, step 174 to compare the change in signal intensity value, a maximum value is obtained. 然后,进行步骤176以决定正在发射信号的第一轮胎状态感测装置的位置, 其中此最大值是在开关天线中的第一天线时所产生的,故第一轮胎状态感测装置对应于第一天线,即第一轮胎状态感测装置检测第一天线所对应的轮胎。 Then, step 176 to determine the position of a first tire condition sensing device is transmitting signals, wherein this maximum is in the antenna switch is generated when the first antenna, so that the first tire condition sensing device corresponding to the antenna, i.e., a first tire condition sensing means for detecting a first antenna corresponding to a tire. 然后,重复上述步骤以一一分别辨识识别出所有轮胎状态感测装置的位置。 Then, repeat the steps to identify the position of eleven respectively identify all of the tire condition sensing apparatus. 由上述本发明较佳实施例可知,应用本发明的优点为:可自动地识别轮胎状态感测装置的位置,大幅地縮短辨识识别时间,因而有效地节省人力物力,并满足消费者的需求。 By the preferred embodiment of the present invention it found that
