200912762 九、發明說明： 【發明所屬之技術領域】 ^發明係有關於一種使用射頻識別找尋物品的技術， 特別疋有關於利用具定位功能之射頻識別讀取裝置以找尋 目標物品的一種方法與裝置。 【先前技術】 找東西是許多人都經歷過的事情，尤其是找不到東西 夺那種著急與焦慮的心情，令人感到不安與無助，總是想 趕快找到東西，並希望下次不要再發生同樣事情。生活週 遭的小東西’如遙控器、鑰匙、文具及日常生活中的物品 種類繁多大小形狀及用途各不相同，因此，在收納管理上 通常是事倍功半，東西使用後常常都是隨處亂放，等到下 次要使用時，花了九牛二虎之力仍然無法找到要使用的東 西，尤其當約會或上班已經快來不及了，但卻找不到車子 或大門鑰匙，以致延誤了約會或上班的時間，除了造成個 人的困擾之外，其有形無形的損失也是一項不低的成本。 我國公告第435106號專利，揭露了 一種具時刻及聲控功 能的鑰匙圈，於上蓋内部設有聲控器’首先使用者先錄好 控制語音（如“鑰匙圈“）並儲存在鑰匙圈内，當使用者 欲找尋該鑰匙圈時，即可以講出控制語音（“鑰匙圈，，）， 當聲控器接受到使用者的控制語音時，該鑰匙圈對所收到 之聲音進行音頻比對，如果比對正確即可令一蜂鳴器產生 聲響並可使發光二極體發出亮光，以方便使用者找尋鑰匙 200912762 圈，雖然該鑰匙圈可以較方便地被找到，但是它仍有下列 ^個缺點：它只適用於鑰匙圈無法方便地普及至其他之物 印（如遙控器或小文具等其他物品）。再者，我們希望能獲 2有用的主動式資訊以指引使用者更快找到物品，如被找 尋之目標物的方位及距離可以顯示在一具有顯示幕之手持 式控制器上，並藉由移動該可檇式控制器，持續更新顯示 幕之方位及距離資訊，方便追蹤目標物之位置，以快速的 找到目松物，但該鍮匙圈並不具備這些功能，因此也不便 ,於被追蹤。最後一點，也是最重要一點就是該鑰匙圈所產 生之回應僅為單調的一種蜂鳴聲及一發光二極體之閃爍信 號更不疋數位#號，因此，無法像數位式信號可以做各 種加值式之運用，以致於該鑰匙圈只適於尋找單一種物 。口，無法像數位信號一樣，可以編碼的方式來識別多種不 同物οσ，並偵測出各物品之方位，更進一步可以物品種類 方式來找尋及對物品分類。 《 近年來由於無線射頻（Radio Frequency)技術之進展 及基於無線射頻技術之優勢，射頻識別技術正被運用在改 善人類的生活。我國公告第565802號專利『使用射頻識 別標蕺之物件追蹤及管理之系統及方法』及美國第 6600418 號之"〇bject track丨ng and management system and method using radio-frequency identification tags"專利揭露了一種使用射頻識別標籤 技術來官理倉庫物品之系統及方法，該發明所使用之無線 射頻讀取裝置並不具定位功能，而是利用位置標藏以獲知 6 200912762 =3舍是說必須事先將倉庫中欲被辨識位置的地 ’(即為位f 位配置了存有位置資訊之射頻識別標籤 過苹位置時1 ’待配有無線射頻讀取裝置的運輸車輛經 r 存：二讀取裝置讀取最接近之位置標籤内所儲

Description of the invention: [Technical field to which the invention pertains] ^The invention relates to a technique for searching for an item using radio frequency identification, and more particularly to a method and apparatus for finding a target item using a radio frequency identification reading device having a positioning function . [Prior Art] Finding things is something that many people have experienced, especially when they can't find things to win the anxiety and anxiety. It is uncomfortable and helpless. They always want to find things quickly and hope not to do it next time. The same thing happens again. The small things around you, such as remote controls, keys, stationery, and everyday objects, vary in size, shape, and use. Therefore, in storage management, it is usually half the effort, and things are often used everywhere. The next time I want to use it, I still can't find what I want to use, especially when I am dating or going to work, but I can't find the car or the door key, which delays the appointment or the time of going to work. In addition to causing personal problems, its tangible and intangible losses are also a low cost. China Patent No. 435106 discloses a key ring with time and voice control function, and a sound controller is arranged inside the upper cover. First, the user first records the control voice (such as "key ring") and stores it in the key ring. When the user wants to find the key ring, the control voice ("key ring,") can be spoken. When the voice controller receives the user's control voice, the key ring performs an audio comparison on the received voice. The correct sound can make a buzzer sound and make the light emitting diode shine, so that the user can find the key 200912762 circle. Although the key ring can be found more conveniently, it still has the following disadvantages. : It only applies to key rings that cannot be easily spread to other items (such as remote controls or small stationery). In addition, we hope to get 2 useful active information to guide users to find items faster. The orientation and distance of the target being searched can be displayed on a handheld controller with a display screen, and the display is continuously updated by moving the portable controller. The position and distance information makes it easy to track the position of the target to quickly find the object, but the key ring does not have these functions, so it is inconvenient to be tracked. The last and most important point is the key. The response generated by the circle is only a monotonous beep and a blinking signal of a light-emitting diode. The number is not more than the number #, therefore, it is impossible to use various value-added signals like digital signals, so that the key ring It is only suitable for finding a single object. The mouth cannot be used to identify a variety of different objects οσ like a digital signal, and to detect the orientation of each item, and further to find and classify the item by the type of item. In recent years, due to the advancement of radio frequency (Radio Frequency) technology and the advantages of radio frequency technology, radio frequency identification technology is being used to improve human life. China Patent No. 565802 "Use of RFID tags for object tracking and management" System and Method" and US 6600418 "〇bject track丨ng and management system and method using ra The dio-frequency identification tags" patent discloses a system and method for using a radio frequency identification tag technology to administer warehouse items. The radio frequency reading device used in the invention does not have a positioning function, but uses a location tag to know 6 200912762 =3she means that the location of the warehouse in which the location is to be recognized must be set in advance (that is, when the radio frequency identification tag with the location information is configured for the bit f position 1 'the transportation vehicle to be equipped with the radio frequency reading device After r: the second reading device reads the n stored in the closest location tag to know the current location information. Although the location of the aforementioned invention L-port storage item is not suitable for finding everyday life: Since the location of the location must be correctly configured before the location tag, it means that the location of the location tag is not configured: the frequency reading device recognizes the location, and in recent years, the radio frequency identification technology has been paralyzed: no, 'f The radio frequency identification system with flaws has also achieved satisfactory results. The principle of using the wireless radio frequency reading device with the clamp function is to use the wireless radio frequency tag to return the signal characteristics of the radio frequency reading device to calculate its orientation, so it is necessary to set the position label, and it is not necessary to configure the position target in advance. The location of the radio frequency tag can be determined at each location, so the aforementioned month is not suitable for finding items in daily life, and the device and method for using the radio frequency identification reading device with positioning function will be disclosed in the present invention. , you can quickly find what you are looking for. SUMMARY OF THE INVENTION The present invention mainly provides a method and apparatus for quickly finding an object 2 using radio frequency identification technology.

The form needs to be established in advance and stored in a non-volatile note. In the actual operation, the normalized module compares the currently used clamp module type with the look-up table method to find out the coordinate system used. And complete the coordinate conversion, and then multiply the magnification, that is, complete the formalization work. Figure 4 is the architecture diagram of the control module. The input module (603) is to receive the data from the input source (before, and to determine whether the input data is the item number or the name of the printed matter, and if it is the item name, the memory is searched. The item number name is for..., the table to find out its item number, used as a search item. The microprocessor (6〇1) negative shell executes the program stored in r〇m(6〇2), and executes in the program. In the process, the input module (603) captures the data, and the data is output to the screen or the system through the output module level 6〇4), while the microprocessor and the RFID reader device need to be read by the radio frequency identification. Communicating with each other through the intermediary of the device interface (605). FIG. 5 is an application example, in which the user can read the name of the item to be found by voice (44). In this embodiment, the name of the item to be found (44) 13 200912762 is taken as an example of the remote control 11 . The microphone remote control is transmitted to the Newridge module and identified as "TV remote control" and displayed on the screen. Refer to the item category name in the memory to check the number of the TV remote control and display it. On the screen, then the positioning module searches for the location of the "Work TV" remote control, and then returns the normalized position information. When t8 is activated, K will send out a distance. The sound of the defined volume and the distance between the length and the volume are inversely proportional, and the result of the search is displayed by using the returned position information as shown in Fig. 6, wherein the direction indicator (42) in the box represents the target to be searched. In the direction in which the object is located, in order to more clearly indicate the position of the object in space, the present invention positions the space in a three-dimensional three-dimensional coordinate, and the larger black dot in the figure is the position of the object. And the smaller gray dot is the coordinate origin, that is, the position of the item searcher (ie, the device of the present invention), the length indicated 3. plus the distance indication indicating the object searcher in the example from the target object ( 43). In addition to finding a single item, the device of the present invention can also search for all items of the same category in a category manner, and the item 7 is a picture for displaying the category, and can be entered by category, or by keyboard, voice or touch screen. The category name is used to find the item. If the information of the input is the category name, the category number can be found through the item category number name comparison table. Figure 8: Search results of the search category items, a total of TV remote control, audio remote control H and air-conditioning remote control | | three remote controls, using the three-dimensional coordinate map to capture the location and distance of each item To inform the user of all the items that can be found in the remote control category and their location. FIG. 9 is a flow chart 14 200912762 stored in the ROM for controlling the operation program of the device of the present invention. Step 922 is to detect whether the input module has any data input, and if there is data input, start searching for the item, step 9 The input data is read. Since the input data may be the item number or the item name, step 926 determines whether the input data is the item number or the item name. If the input data is an Arabic number, the item number is , the reverse is the item name, and when the input data is the item name, step 928 uses the look-up table method to find the item number corresponding to the input item name, because the first two codes in the item number (may also be the previous code or The first three yards, etc., may be the category code by the user mosquito, step 93 (3 may be determined by the length of the number to determine the number of the category or the number of the item, and if it is the category number, perform the category search of FIG. 9 as in step 932. Step, if searching for a single item, skip to 934 and send the item number to the m group through the RFID device interface to search The position of the item, and step 936 reads back the position information from the positioning module through the RFID device interface. Next, the volume of the sound emitted by the position information output to the 骸κ determines the position of the item. The closer the volume is, the smaller the volume is. The farther the volume is, the smaller the volume is. This can be obtained by querying the previously defined distance volume comparison table. Step 94G outputs the position information to the screen, and in step 942, the input module is determined. Is there any new information to enter to decide whether to start the other two search work? If there is new information, go back to step 924 to start another search work. Otherwise, it means that it is still searching for the original item. In order to enable the dog to continue to move the device of the present invention by relying on I, the user can move the invention in the direction indicated by the screen, and re-detect the distance of the article every predetermined time, and continue to output to The speaker 盥 screen, to increase the distance of the user's items, speed up the search for items, so step 15 200912762 944 to wait for a predetermined time, then return to the step The distance 'and the same way as above - 4 re-detected until the user initiates another new search, m48's work 948 is also (4) 934 to step 944, the steps are implemented by interruption or event In order to improve the interval, it can be set by the user. 1 The length of the time The search process of the category of Figure 10 first searches for the category of the category to be searched in the name comparison table of step 95 (assuming the item category number name comparison table) The first position determines whether the current k-th data is in the category, this; the 类别 954: 195 product number category code can know whether it is the same category of goods, if not ^ YES = step 962 shows all the items returned After the position ends the class another ^ search brother 'inversely, step 956 will be the k-th article σ edit = to search for its location, step 958 record its = not used 'because of the same category of article number name comparison data will be stored mr set , so the step will move to the next-pen record (coming soon), and then return to step 954 to determine if the next item number is still: - category continues to send the item number to the final group to search for the straight position Similarly, the positioning module returns bits of information stored down, repeat the same action - until the item number no longer belongs to halt its operation when the search To find a category, and location of receipt of the information displayed on the screen. Figure 11 shows the interface for creating an item category. The button for recording the “Vote attern” is used to record the voice signal of the category name, so that the voice module can be used for voice (4). The function of Figure 12 is similar to that of Figure u. Figure 200912762 12 It is used to create or modify the item data. The voice signal of the item name is recorded in the system of “VNce with em”, which is used together with Figure 11 for voice recognition of the voice module. The invention has many advantages, such as when searching for an item, by moving the volume of the human speaker, the volume of the sound of the human being is searched by the small and large representative, and the device is closer and closer, that is, the direction of the movement is correct, and vice versa. If the volume of the axe sound is from the big and small, the item searched is farther and farther away from the device of the present invention', that is, it should move in the opposite direction to find the object mechanism so that the item is quickly and easily found. Category, if you do not lose any category information, it will show the location of the object near the device of the present invention. 'This can quickly grip the drawer or the contents of the cabinet when sorting drawers and cabinets', so that the finishing work can do more with less. Effect: In terms of design, since the positioning module includes a normalized module, Z 乂 uses a radio frequency identification reading device with different functions produced by different manufacturers, which makes the product more flexible.
