The superiority of the technical content revealed by this project enables the single radio frequency identification device to achieve a multi-dimensional reading range and reduce the cost of installing multiple RFID readers. ° Refer to the heading 'Continuing the above paragraph, the "Multi-Dimensional Antenna Array RF Reader Device" mainly includes: "Resonance Chi Dimensions to Recording Space Row = Antenna _ 14 and - Resonant Capacitor 15" - Group The control device 12 is used to select the power frequency amplifier U or the carrier frequency signal provided by the shock blue source circuit 1 , and the antenna in the array 14 to generate an electromagnetic field, which can be used to detect the ___, when _ just magnetic field will be 5 200925547 to generate the identification code signal, the identification code signal will be selected by the controller 12 into the packet detector 18, the filtering and amplifying circuit 17, allowing the microprocessor module 16 to record its identification code and position, using this scanning switch In the switching mode, any one of the antenna arrays μ is activated one by one to record the identification codes of the radio frequency identification tags located in different spatial (different dimensions) positions. Referring to the second figure (A), the figure shows a schematic diagram of the antenna switching controller. The figure is a set of two switches in the controller 23, respectively displaying the control switches "on" and "〇ff", and when the control signal is displayed as "on" state, the carrier oscillation source is allowed to enter the antenna 14 controlled thereby. On the other hand, if the control signal is displayed as "0ff", the carrier oscillation source is not allowed to enter the antenna 14 controlled by it. Referring to Figure 2(B)', this figure shows a more detailed implementation of the controller 12. As shown in the figure, the controller 12 includes a plurality of pairs of switching switches (SW-1〇... SWJ〇' is respectively connected with a packet detector 18 and a transmitting module 19 to tap each group antenna (antenna 1) ·.. Antenna N). The controller 12 only turns on a specific set of switching switches per unit time, and turns off the remaining switching switches. When the switch SWJ is "〇n" (SW-2. · SW_N In the "off" state, if the RFID reader reads the identification code of the RFID tag, it indicates that there is an RFID tag at the location (coordinate) of the antenna 1. Based on this, the tracker is to be tracked. The surface of the positioned object is attached with a radio frequency identification mark. When the item enters the reading range of the antenna 1, the item can be detected at the position of the antenna 1. Referring to the third figure, the figure shows the multi-dimensional antenna. Array of Radio Frequency Identification Card Reader 6 200925547 Embodiment of the device. This embodiment is an inductive three-dimensional puzzle, which is divided into nine money areas, each antenna surface is provided with an antenna 14, a puzzle Block 20 is labeled with an RFID tag, when the puzzle piece 2〇 When the stereo puzzle board is on the three-dimensional puzzle board, the three-dimensional puzzle board can be side-mounted on the surface or in the presence or absence of a misplaced position to achieve the positioning effect. According to the foregoing paragraphs, based on multiple antennas (multi The positioning method of the coffee (four) array mode needs to use a set of controllers 12 to scan and switch each group of antennas, and the intensity of the RF signal nicknames will be reduced in the antennas of the antennas 14 to reduce the sensitivity of the readers. In addition, the antenna switching mode is used to increase the reading range, and the actual situation of each antenna cannot be synchronized. The main purpose of the present invention is to provide a positioning system for a multi-radio touch reader. The positioning system is composed of a plurality of radio frequency identification readers, and each of the radio frequency identification readers is provided with a unique identification code 'adjacent to each other to form a tracking network capable of tracking sideways. When the tagged item enters the reading mode of any radio frequency identification reader to which the positioning system belongs, the RFID reader can instantly reply to the back end (user) of the system. To the purpose of real-time monitoring, tracking and squatting. The fourth (in this), the structure of the 纽 系 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ It is less likely that the item is not detected and read. Another aspect of the present invention is the architecture of the multi-radio identification reader to achieve the function of 7 200925547 item location tracking, which is based on the conventional knowledge. The positioning method of the architecture of the RFID reader device with multi-dimensional antenna array, the radio frequency (RF) signal of the radio frequency identification reader is not swiveled by the antenna, and the attenuation is reduced. Based on this, the main implementation of this (4) (10) provides - read H from the computer and a plurality of RF identification, the Lai has a new office; the Wei Pai frequency identification reader 'each set with a unique - The coordinate identifier is connected to the serial power of the computer and is placed at the position of the desired item or its path of travel. When the surface (or internal) is attached with the RFID tag, the item is stopped. The thief is identified by any radio frequency When the reading range of the reader is known, the computer can use the coordinate identification code to know the location of the item. Continuation of the above and another embodiment of the present invention can also be judged by using the serial number of the computer itself. When the RFID reader is connected to the computer, the computer will give each RFID reader.

The plural side depends on _ take (four) 234, then (four) take in the shot Identifying the identification code of the tag. The RFID readers 312 each set a standard identification code, the coordinate _ code has a uniqueness, representing a non-coordinate position. When an item with a radio frequency identification tag is attached, When the reading range of any radio frequency identification reader (such as 301) of the status system is read, the item can be judged to be in the detection range of the radio frequency identification reader (such as 301). Referring to the fifth figure, The figure shows an embodiment of the positioning system of the multi-radio frequency identification reader of the present invention. The fifth embodiment is continued. The computer 4 of the embodiment utilizes the office interface to interact with each radio frequency identification reader (3 〇 312) Data transmission, wherein a hub 4 〇i (hub) is connected to the computer 4 and a plurality of radio frequency identification readers (301 312 312).
