Description
本發明是有關於一種無線通訊技術，特別是用於改變磁場方向的一種裝置，一種可延長射頻標籤可工作範圍的一種裝置。 The present invention relates to a wireless communication technology, and more particularly to a device for changing the direction of a magnetic field, a device that extends the range of operation of a radio frequency tag.
目前在射頻(Radio Frequency，RF)無線讀取的技術上，射頻標籤(Tag)在具有單一天線的射頻讀取器所能讀取的範圍為射頻讀取器的天線周圍的圓形或橢圓形磁場範圍。若欲改變射頻標籤被讀取的位置時，通常也必須一起改變射頻讀取器的天線位置。此外，於射頻讀取器讀取立體外形的射頻標籤的情況中，當立體外形的射頻標籤穿過射頻讀取器天線的中間時，容易發生射頻標籤通過可讀取範圍的時間過短而無法順利被讀取的情形。或者，若射頻標籤由讀取死角方向通過射頻讀取器天線，則造成射頻標籤無法得到足夠可工作的能量，由於此時亦無法改變射頻標籤的方向，因而導致射頻讀取器漏失射頻標籤資料。 Currently, in the radio frequency (RF) wireless reading technology, a radio frequency tag (Tag) can be read by a radio frequency reader having a single antenna in a circular or elliptical shape around the antenna of the radio frequency reader. Magnetic field range. If you want to change the position where the RF tag is read, you must also change the antenna position of the RF reader together. In addition, in the case where the radio frequency reader reads the stereoscopic shape of the radio frequency tag, when the stereoscopic shape radio frequency tag passes through the middle of the radio frequency reader antenna, it is easy for the radio frequency tag to pass the readable range for too short time.

為了說明讀取距離，請參考第1圖。讀取器110連接線圈單元121以偵測原讀取距離X之內的無線訊號，其中無線訊號係來自原讀取距離X之內的資料產生模組130。具體而言，微控制單元140(例如微控制器)控制讀取器110透過連接的線圈單元121產生磁場，而磁場可涵蓋的最遠距離即為原讀取距離X。位於原讀取距離X內的資料產生模組130藉由磁場轉換出電能，而達到可工作電能時，資料產生模組130無線傳送資料(亦即無線訊號)至讀取器110，因此讀取器110可讀取資料產生模組130傳送的資料。換言之，讀取距離亦可表示資料產生模組130的可工作範圍。 To illustrate the reading distance, please refer to Figure 1. The reader 110 is connected to the coil unit 121 to detect a wireless signal within the original reading distance X, wherein the wireless signal is from the data generating module 130 within the original reading distance X. Specifically, the micro control unit 140 (eg, a microcontroller) controls the reader 110 to generate a magnetic field through the connected coil unit 121, and the farthest distance that the magnetic field can cover is the original read distance X. The data generating module 130 located in the original reading distance X converts the electric energy by the magnetic field, and when the working power is reached, the data generating module 130 wirelessly transmits the data (that is, the wireless signal) to the reader 110, so the reading is performed. The device 110 can read the data transmitted by the data generating module 130. In other words, the read distance may also indicate the operable range of the data generation module 130.
上述原讀取距離X取決於讀取器110、線圈單元 與資料產生模組的設計。原讀取範圍X的範圍約在數公分(cm)至數十公分(cm)之間。 The above original reading distance X depends on the reader 110 and the coil unit Design with the data generation module. The range of the original reading range X is between about several centimeters (cm) to several tens of centimeters (cm).
第2圖係說明本揭示內容一實施例之電子裝置示意圖。電子裝置包含讀取器110與複數個線圈單元120(包含線圈單元121、122)，其中讀取器110連接線圈單元121。讀取器110用以讀取無線訊號(例如來自資料產生模組130的無線訊號)。線圈單元122與線圈單元121沿著直線排列，並且線圈單元121、122的間距為d1，其中間距d1小於或等於原讀取距離X。換言之，線圈單元122位於可讀取距離X之內，並用以與連接讀取器110的線圈單元121產生磁耦合，以延伸原讀取距離X為延伸讀取距離。於本實施例中，資料產生模組130可放置於距離線圈單元122間距d2的位置，延伸讀取距離為間距d1加上間距d2，因此讀取器110可讀取到延伸讀取距離(d1+d2)之內的資料產生模組130發送的無線訊號。換言之，資料產生模組130的可工作範圍延伸為(d1+d2)。此處所述的原讀取範圍、延伸讀取範圍均指與線圈單元121的間距。 2 is a schematic diagram of an electronic device according to an embodiment of the present disclosure. The electronic device includes a reader 110 and a plurality of coil units 120 (including coil units 121, 122), wherein the reader 110 is coupled to the coil unit 121. The reader 110 is configured to read a wireless signal (eg, a wireless signal from the data generation module 130). The coil unit 122 and the coil unit 121 are arranged along a straight line, and the pitch of the coil units 121, 122 is d1, wherein the pitch d1 is less than or equal to the original reading distance X. In other words, the coil unit 122 is located within the readable distance X and is used to magnetically couple with the coil unit 121 connected to the reader 110 to extend the original read distance X to the extended read distance. In this embodiment, the data generating module 130 can be placed at a distance d2 from the coil unit 122, and the extended reading distance is the distance d1 plus the spacing d2, so the reader 110 can read the extended reading distance (d1). The data within the +d2) generates a wireless signal transmitted by the module 130. In other words, the workable range of the data generation module 130 extends to (d1+d2). The original read range and the extended read range described herein all refer to the pitch from the coil unit 121.
具體而言，上述線圈單元122與線圈單元121共振以延伸讀取器透過線圈單元121產生的磁場範圍。實作上，線圈單元122可包含電容器C，並根據線圈單元設計選擇適當電容值的電容器C，以決定與線圈單元121相同的共振頻率f。舉例而言，L為線圈單元122的等效電感值，C為電容器(例如共振電容器)的電容值，則線圈單元122的共振頻率f可由下列公式計算得出：
於另一實施例，線圈單元121與122具有相同尺寸，並且間距d1等於原讀取距離X。如此一來，讀取器110可讀取兩倍的原讀取距離X之內的無線訊號，亦即延伸讀取距離(資料產生模組130的可工作範圍)為2X。舉例而言，若原讀取距離X為6公分，則延伸讀取距離可達到12公分。 In another embodiment, the coil units 121 and 122 have the same size, and the spacing d1 is equal to the original reading distance X. In this way, the reader 110 can read twice the wireless signal within the original reading distance X, that is, the extended reading distance (the working range of the data generating module 130) is 2X. For example, if the original reading distance X is 6 cm, the extended reading distance can reach 12 cm.
於增加線圈單元120數目的一實施例中，如第3圖所示，第3圖的電子裝置除了於線圈單元122與資料產生模組130之間增加線圈單元123以外，其餘硬體與第2圖的電子裝置實質上相同。線圈單元121、122與123沿著直線排列，並且線圈單元122與123的間距d2小於或等於原讀取距離X。資料產生模組130可放置於距離線圈單元123間距d3的位置。操作上，讀取器110透過連接的線圈單元121產生磁場。線圈單元122與連接讀取器110的線圈單元121產生磁耦合，並且線圈單元123與線圈單元122產生磁耦合，因此延伸讀取距離可延長為間距d1、d2、d3的總和，亦即(d1+d2+d3)。線圈單元123的實作方式類似於線圈單元122，此處不再重複敘述。如上所述，當位於延伸讀取距離(d1+d2+d3)內的資料產生模組130由磁場轉換出可工作電能時，傳送無線訊號至讀取器110，讀取器110於是讀取到無線訊號。 In an embodiment in which the number of coil units 120 is increased, as shown in FIG. 3, the electronic device of FIG. 3 adds the coil unit 123 between the coil unit 122 and the data generating module 130, and the second hardware and the second The electronic devices of the figures are substantially identical. The coil units 121, 122, and 123 are arranged along a straight line, and the pitch d2 of the coil units 122 and 123 is less than or equal to the original reading distance X. The data generation module 130 can be placed at a distance d3 from the coil unit 123. In operation, the reader 110 generates a magnetic field through the connected coil unit 121. The coil unit 122 is magnetically coupled with the coil unit 121 connected to the reader 110, and the coil unit 123 and the coil unit 122 are magnetically coupled, so that the extended reading distance can be extended to the sum of the pitches d1, d2, d3, that is, (d1) +d2+d3). The coil unit 123 is implemented in a manner similar to the coil unit 122 and will not be repeated here. As described above, when the data generation module 130 located within the extended read distance (d1+d2+d3) converts the operable power from the magnetic field, the wireless signal is transmitted to the reader 110, and the reader 110 then reads Wireless signal.
於另一實施例，線圈單元121、122、123具有相同尺寸，並且間距d1、d2均等於原讀取距離X。如此一來， 讀取器110可讀取三倍的原讀取距離X之內的無線訊號，亦即延伸讀取距離為3X。舉例而言，若原讀取距離X為6公分，則延伸讀取距離可達到18公分。 In another embodiment, the coil units 121, 122, 123 have the same size, and the spacings d1, d2 are equal to the original reading distance X. As a result, The reader 110 can read three times the wireless signal within the original reading distance X, that is, the extended reading distance is 3X. For example, if the original reading distance X is 6 cm, the extended reading distance can reach 18 cm.
如上所述，本揭示內容透過增加連接讀取器110的線圈單元121與資料產生模組130之間的線圈單元(例如線圈單元122、123、...)的數目，依照線圈單元的排列順序產生磁耦合，以有效地延伸讀取器110的讀取距離。前述耦合的線圈單元(例如線圈單元122、123、...)數目將視讀取器110的發射功率以及耦合過程的衰減量而決定。舉例而言，於有效磁耦合的情況中，沿著直線排列的線圈單元120數目為正整數N並具有相同尺寸，則延伸讀取距離為N倍的原讀取距離X，亦即延伸讀取距離為(N*X)。 As described above, the present disclosure increases the number of coil units (eg, coil units 122, 123, . . . ) between the coil unit 121 and the data generation module 130 connected to the reader 110 in accordance with the arrangement order of the coil units. Magnetic coupling is produced to effectively extend the read distance of the reader 110. The number of coupled coil units (e.g., coil units 122, 123, ...) will depend on the transmit power of the reader 110 and the amount of attenuation of the coupling process. For example, in the case of effective magnetic coupling, the number of coil units 120 arranged along a straight line is a positive integer N and has the same size, and the original reading distance X of the reading distance N is extended, that is, extended reading The distance is (N*X).
第4圖係說明本揭示內容一實施例之電子裝置示意圖。電子裝置包含讀取器110、線圈單元121~125與可撓支撐單元450，其中可撓支撐單元具有中空通道。線圈單元121~125沿著可撓支撐單元450表面設置，以調整延伸讀取距離之方向為沿著中空通道，亦即線圈單元121~125依照可撓支撐單元450的彎曲方向而可沿著直線方向、曲線方向或其他方向排列。如第4圖所示，當線圈單元121~125沿著曲線間隔排列時，相鄰兩個線圈單元間距d1~d4均滿足至少有一方向的間距小於或等於原讀取距離X，則線圈單元121~125可依序產生磁耦合。如此一來，延伸讀取距離涵蓋中空通道內部，以及中空通道外部距離線圈單元125間距d5的範圍，其中間距d5小於或等於原讀取距離X。 因此，當資料產生模組130位於可撓支撐單元450的中空通道內的任何位置時，由於讀取死角的減少，因而提高資料產生模組130達到可工作電能而發送無線訊號至讀取器110的機率。 4 is a schematic diagram of an electronic device according to an embodiment of the present disclosure. The electronic device includes a reader 110, coil units 121-125 and a flexible support unit 450, wherein the flexible support unit has a hollow passage. The coil units 121-125 are disposed along the surface of the flexible supporting unit 450 to adjust the direction of the extended reading distance along the hollow passage, that is, the coil units 121-125 can follow the straight line according to the bending direction of the flexible supporting unit 450. Arrange in direction, curve direction, or other directions. As shown in FIG. 4, when the coil units 121-125 are arranged along the curve interval, the adjacent two coil unit pitches d1 to d4 satisfy that at least one direction of the pitch is less than or equal to the original reading distance X, and the coil unit 121 ~125 can generate magnetic coupling sequentially. In this way, the extended reading distance covers the inside of the hollow channel, and the range of the outer distance of the hollow channel from the distance d5 of the coil unit 125, wherein the spacing d5 is less than or equal to the original reading distance X. Therefore, when the data generating module 130 is located at any position in the hollow channel of the flexible supporting unit 450, the data generating module 130 is enabled to reach the operable power and transmit the wireless signal to the reader 110 due to the reduction of the read dead angle. The chance.
第4圖與第5圖的線圈單元121~125係沿著不同曲線排列，亦即可撓支撐單元450的彎曲狀況不同。如上所述，第5圖的線圈單元121~125中相鄰兩個線圈單元的間距d1~d4均滿足至少有一方向的間距小於或等於原讀取距離X，則線圈單元121~125可依序產生磁耦合。如此一來，延伸讀取距離涵蓋中空通道內部，以及中空通道外部距離線圈單元125間距d5的範圍，其中間距d5小於或等於原讀取距離X。因此，延伸讀取距離的方向可透過線圈單元121~125排列方式調整。於一實施例中，由於線圈單元121~125係設置於可撓支撐單元450表面，則調整可撓支撐單元450的方向亦可調整延伸讀取距離的方向。於另一實施例中，線圈單元整合於可撓支撐單元450。 The coil units 121 to 125 of FIGS. 4 and 5 are arranged along different curves, that is, the bending state of the flexible supporting unit 450 is different. As described above, the pitches d1 to d4 of the adjacent two coil units in the coil units 121 to 125 of FIG. 5 satisfy that the pitch of at least one direction is less than or equal to the original read distance X, and the coil units 121 to 125 can be sequentially Magnetic coupling is produced. In this way, the extended reading distance covers the inside of the hollow channel, and the range of the outer distance of the hollow channel from the distance d5 of the coil unit 125, wherein the spacing d5 is less than or equal to the original reading distance X. Therefore, the direction in which the reading distance is extended can be adjusted by the arrangement of the coil units 121 to 125. In one embodiment, since the coil units 121-125 are disposed on the surface of the flexible supporting unit 450, adjusting the direction of the flexible supporting unit 450 can also adjust the direction of extending the reading distance. In another embodiment, the coil unit is integrated into the flexible support unit 450.
第4、5圖的線圈單元122~125的實作方式類似於第2圖的線圈單元122，此處不再重複敘述。 The coil units 122 to 125 of Figs. 4 and 5 are similar to the coil unit 122 of Fig. 2 and will not be described again.
於一應用情境中，使用者可將資料產生模組130投入可撓支撐單元450的中空通道，而進入中空通道的資料產生模組130發送的無線訊號可持續被讀取器110所讀取。於另一應用情境中，亦可調整可撓支撐單元450的彎曲方式以因應不同的使用情況(例如使用者由不同方向投入資料產生模組130至中空通道)。 In an application scenario, the user can input the data generation module 130 into the hollow channel of the flexible support unit 450, and the wireless signal sent by the data generation module 130 entering the hollow channel can be read by the reader 110. In another application scenario, the bending manner of the flexible supporting unit 450 can also be adjusted to respond to different usage situations (for example, the user inputs the data generating module 130 to the hollow channel from different directions).
於一實施例中，如第6圖所示，讀取器110可連接多組複數個線圈單元120、650、660，其中讀取器110可支援多天線應用並連接至線圈單元121、651、661。多組複數個線圈單元120、650、660分別設置於可撓支撐單元451、452、453表面。多組複數個線圈單元120、650、660的線圈單元數目可相同或不同。可撓支撐單元451、452、453的長度與彎曲狀況可相同或不同。如上所述，多組複數個線圈單元120、650、660分別由線圈單元121、651、660開始，依序產生磁耦合以產生不同類型的延伸讀取距離。因此，第6圖所示的電子裝置可達到多位置、多方向的延伸讀取距離組合以因應不同使用情境。 In an embodiment, as shown in FIG. 6, the reader 110 can connect a plurality of sets of coil units 120, 650, 660, wherein the reader 110 can support multiple antenna applications and be connected to the coil units 121, 651, 661. A plurality of sets of coil units 120, 650, 660 are respectively disposed on the surfaces of the flexible support units 451, 452, and 453. The number of coil units of the plurality of sets of coil units 120, 650, 660 may be the same or different. The lengths of the flexible support units 451, 452, 453 and the bending conditions may be the same or different. As described above, the plurality of sets of coil units 120, 650, 660 are respectively started by the coil units 121, 651, 660, sequentially generating magnetic coupling to produce different types of extended read distances. Therefore, the electronic device shown in FIG. 6 can achieve a multi-position, multi-directional extended read distance combination to cope with different usage scenarios.
於一實施例中，本揭示內容的電子裝置可透過一組線圈單元120讀取多個資料產生模組731~733的無線訊號，如第7圖所示。線圈單元121~124設置於可撓支撐單元450的表面，並且沿著一直線排列。線圈單元121連接讀取器110，如上述，延伸讀取範圍涵蓋可撓支撐單元450的中空通道內。資料產生模組731~733垂直通過中空通道的時間均足以達到可工作電能以傳送無線訊號至讀取器110，進而受到讀取器110讀取。 In one embodiment, the electronic device of the present disclosure can read the wireless signals of the plurality of data generating modules 731-733 through a set of coil units 120, as shown in FIG. The coil units 121 to 124 are disposed on the surface of the flexible supporting unit 450 and arranged along a straight line. The coil unit 121 is coupled to the reader 110, and as described above, the extended reading range encompasses the hollow passage of the flexible support unit 450. The data generation modules 731-733 are vertically passed through the hollow channel for a time sufficient to reach the operable power to transmit the wireless signal to the reader 110, which is then read by the reader 110.
於一實施例中，多個線圈單元亦可具有不同尺寸。如第8圖所示，線圈單元821~823依尺寸由小到大間隔設置於錐形的可撓支撐單元850表面，其中最小的線圈單元821連接讀取器110。線圈單元821~823的間距根據線圈單元822、823的耦合磁場強度進行調整。舉例而言，線圈單 元821~823的間距依照線圈單元尺寸減小而減小。換言之，線圈單元823、822的間距大於線圈單元822、821的間距。如此一來，本揭示內容可延伸磁場、改變磁場方向以及擴展磁場面積，進而達到不同型態的延伸讀取距離，亦即不同型態的資料產生模組130可工作範圍。 In an embodiment, the plurality of coil units may also have different sizes.

The pitch of the coil units 921 to 925 is adjusted in accordance with the strength of the coupled magnetic field of the coil units 922 to 925. For example, the pitch of the coil units 921 to 925 is reduced in accordance with the reduction in the size of the coil unit. In other words, the pitch of the coil units 921, 922 is the largest, and the pitch of the coil units 924, 925 is the smallest. In this way, the disclosure can extend the magnetic field, change the direction of the magnetic field and the magnetic field density, and reduce the magnetic field area to make the magnetic field have directivity, thereby achieving different extended reading distances, that is, different types of data generating modules. 130 can work range.
