Description

  The present invention relates to an IC tag recognition system, an IC tag recognition method, an IC tag recognition system carried by an elevator user, and an IC tag recognition method carried by an elevator user.

  An IC tag (or RFID (Radio Frequency IDentification)) is a small chip of several millimeters size made of a semiconductor element. The IC tag can perform wireless communication with the IC tag reader, and information can be recorded on the IC tag using the IC tag reader, or information recorded on the IC tag can be read out.

  When an IC tag is attached to an article, information on the manufacturing process and distribution process of the article can be sequentially recorded on and read from the IC tag. Therefore, the IC tag is expected to be widely used for inventory management of goods. In addition, by issuing an IC tag to a specific individual, it can be applied to management of entrance / exit and personal information.

Under such circumstances, Patent Document 1 discloses a technique for enhancing services for building users while identifying personal information using an IC tag.
JP 2003-242229 A

  In realizing the system disclosed in Patent Document 1, the IC tag and personal information of the building user worn on the IC tag must be remotely detected by the IC tag reader. That is, when a building user (pedestrian) passes through the passage, it is extremely inefficient to bother to stop in front of the IC tag reader and wait for the IC tag to be reliably recognized, and then start walking again. . Therefore, it is necessary to reliably read the IC tag from a remote location without restricting pedestrian behavior.

  However, depending on the positional relationship (angle) and distance between the IC tag and the IC tag reader, radio wave characteristics (magnetic field strength) may be weakened, and in some cases, personal information may not be read. As described above, there is a concern that the possibility of a detection error is potentially increased as the convenience of the IC tag is pursued.

  If this situation occurs when applied to a security system that automatically authenticates individuals, not only will personal information not be obtained at all, but the security system function may be impaired and there may be concerns about ensuring safety. turn into.

  Therefore, the present invention provides an IC tag recognition system and a recognition method capable of more reliably accessing information in an IC tag with a simple configuration, and more reliably accessing an elevator user's personal information. It is an object of the present invention to provide an elevator user recognition system and a recognition method that can be used.

  A third feature of the embodiment of the present invention is that in the IC tag recognition system for elevator users, information recorded on the IC tag carried by the elevator user who passes through the passage used by the elevator user. A plurality of readers installed at different reading angles to be read, a position information recognition unit for grasping a passing state of the IC tag of the elevator user from information read by the plurality of readers, and the IC of the elevator user who has passed A unique information recognition unit that recognizes the unique information recorded in the tag, and an operation control unit that controls the operation of the elevator based on an instruction from the unique information recognition unit.

  A fourth feature according to the embodiment of the present invention is that, in the elevator tag IC tag recognition method, information recorded on the IC tag carried by the elevator user passing through the passage used by the elevator user is stored. A step of reading by a plurality of readers installed at different reading angles, a step of grasping the passing state of the IC tag of the elevator user from the information read by the plurality of readers by the position information recognition unit, and the elevator that has passed A step of recognizing the unique information recorded in the IC tag of the user by the unique information recognition unit, and a step of controlling the operation of the elevator by the operation control unit based on an instruction from the unique information recognition unit.

  According to the present invention, an IC tag recognition system and a recognition method that can more reliably access information in an IC tag with a simple configuration, and more reliable access to personal information of elevator users. It is possible to provide a recognition system and a recognition method for an elevator user who can perform the above.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  As for the IC tag recognition system and the IC tag recognition method according to the present embodiment, for example, a user who uses an elevator in a building that is one form of a method of using the IC tag recognition system and the IC tag recognition method (hereinafter, use The IC tag recognition system and the elevator user's IC tag recognition method will be described below.

  In the present embodiment, personal information of each user necessary for using the office, tenant, facility, elevator, etc. in the building is input in advance to the IC tag issued to the user. It is assumed that each user is carrying it.

  The IC tag recognition system according to the embodiment of the present invention is provided, for example, in a passage in a building. As shown in FIG. 1 or FIG. 2, an elevator 2 as an example of an elevator is installed behind the passage 1. Two readers 3a and 3b for reading all information recorded in the IC tag carried by the user are installed at a position facing the passage 1 from the upper side to the lower side. A user (not shown) carrying an IC tag that intends to use the elevator 2 proceeds along the Z direction shown in FIG. 1 or 2 and gets into the elevator 2 installed in the back of the passage 1. In the present embodiment, the description will be made assuming that two readers 3 are installed. However, the number of readers 3 is not limited to two, and a plurality of readers 3 may be installed.

  While the user travels along the passage 1 to get into the elevator 2, the IC tag recognition system 10 reads all the information recorded in the IC tag. As shown in FIG. 3, the IC tag recognition system 10 includes a plurality of readers 3a and 3b and IC tags 4a, 4b, and 4c (hereinafter, the plurality of IC tags are collectively referred to as an IC tag 4 as appropriate). An information recognition unit 7 having a position information recognition unit 5 for comparing position information and the like, a unique information recognition unit 6 that makes a determination based on the information from the position information recognition unit 5 and the information of the IC tag 4 received by itself, And an operation control unit 8 that controls the operation of the elevator based on information from the unique information recognition unit 6.

  The readers 3 a and 3 b are devices for reading information recorded in the IC tag 4. Here, there are a plurality of methods for the reader to read information recorded on the IC tag, and the following method is given as an example. That is, as shown in the flowchart of FIG. 4, between the IC tag 4 and the readers 3a and 3b, first, radio waves are transmitted from the antennas provided in the readers 3a and 3b (ST1). The IC tag 4 is activated when the antenna of the IC tag 4 receives this radio wave (ST2). The IC tag 4 incorporates an IC chip capable of recording various information, and when the IC tag 4 is activated, the recorded information is transmitted from the antenna of the IC tag (ST3). . The transmitted information is received by the antennas of the readers 3a and 3b (ST4) and processed by, for example, a connected information processing device (in this embodiment, the unique information recognition unit 6).

  As described above, the readers 3a and 3b are installed at positions facing the passage 1 from above, and are installed at different angles with respect to the passage 1. That is, as shown in FIG. 1, the reader 3a is tilted in the + X direction with respect to the vertical direction (−Y direction), and the reader 3b is tilted in the −X direction with respect to the vertical direction (−Y direction). Yes. Further, as shown in FIG. 2, which is an overhead view of the passage 1, the reader 3a is in the + X direction with respect to the −Z direction, and the reader 3b is in the −X direction with respect to the −Z direction. Tilted. This is because the radio wave transmitted from the IC tag is generally directional, and the radio wave transmitted from the IC tag 4 cannot be read accurately depending on the angle of the reading surface of the readers 3a and 3b. Therefore, by setting a plurality of readers at different angles, it is possible to set different reading areas and increase the possibility of receiving radio waves. The multiple readers are not installed so that their reading surfaces face each other, but are installed in a position and a direction in which any of the multiple readers can simultaneously receive radio waves transmitted from the IC tag. As long as it is installed, it can be installed at any angle.

  Although not specifically shown here, the IC tag 4 has an IC chip in which various types of information are recorded, and an antenna for transmitting information on the IC chip. Various information can be recorded on the IC chip, but in this embodiment, personal information of the user is recorded. As an example of this personal information, for example, the serial number assigned to each IC tag and the information such as “name”, “affiliation”, “permitted destination floor” of the user carrying the IC tag 4 are recorded. ing.

  The position information recognition unit 5 is a part having a role of capturing the presence of the IC tag 4 when a user carrying the IC tag 4 passes through the passage 1 in which the readers 3a and 3b are installed. The position information recognition unit 5 includes a receiving unit 5a that receives information of the IC tag 4 read by the readers 3a and 3b, and a comparison unit 5b that compares the contents of information transmitted from the readers 3a and 3b. The transmission unit 5c transmits the comparison result to the unique information recognition unit 6. The “position” in the position information recognition unit 5 does not mean a specific distance between the readers 3 a and 3 b and the IC tag 4, for example, but a plurality of positions captured by the readers 3 a and 3 b. It means the number of IC tags 4 and the relative positional relationship.

  The unique information recognition unit 6 is a part that collates and determines the information of the IC tag 4 transmitted from the position information recognition unit 5 and the information of the IC tag 4 received from the readers 3a and 3b by itself. Further, information necessary for controlling the operation of the elevator 2 is selected. The “unique information” here refers to personal information recorded in an IC tag carried by each user. The unique information recognition unit 6 includes a receiving unit 6a that receives information from the readers 3a and 3b or the position information recognition unit 5, a storage unit 6b that temporarily stores information received from the readers 3a and 3b, A determination unit 6c that collates and selects information of the IC tag 4 transmitted from the position information recognition unit 5 and information of the IC tag 4 received from the readers 3a and 3b by itself, and information selected by the determination unit 6c Is transmitted to the operation control unit 8.

  The information recognition unit 7 includes the above-described position information recognition unit 5 and unique information recognition unit 6. In the present embodiment, the information recognition unit 7 is configured as described above. However, the position information recognition unit 5 and the unique information recognition unit 6 may be configured by independent devices.

  The operation control unit 8 is a part that controls the operation of the elevator 2 based on the information of the IC tag 4 transmitted from the information recognition unit 7. Information transmitted from the information recognition unit 7 is limited to information necessary for operation of the elevator 2 such as “permitted destination floor” among various information recorded in the IC tag 4.

  In such a configuration, processing of information recorded in the IC tag 4 in the present embodiment is performed as shown in the flowchart of FIG.

  When a user carrying an IC tag travels along the passage 1 trying to get on the elevator 2, the readers 3a and 3b installed on the upper wall surfaces on both sides of the passage 1 recognize the IC tag and record it in the IC tag. Reading of the stored information is started (ST10). Reading is performed along the flow of the flowchart of FIG. 4 described above, for example. At this time, the number of IC tags read by the readers 3a and 3b may be singular or plural. Note that the distance from the reader to the IC tag may be detected by the principle of triangulation.

  Next, it is determined which reader 3a, 3b has read the information of the IC tag (ST11). That is, the position information recognition unit 5 determines whether the information recorded in the IC tag 4 is received by the reception unit 5a in the position information recognition unit 5 via the readers 3a and 3b.

  As a result of the determination, when the readers 3a and 3b recognize the IC tag 4 passing therethrough and none of the readers 3a and 3b have read the information of the IC tag (N in ST11). Further, it is determined whether only one reader has read (ST12). As a result of this determination, if it is determined that the information does not enter the receiving unit 5a in the position information recognizing unit 5 (N in ST12), both the readers 3a and 3b use the information in the IC tag 4. It can be determined that the data could not be read. Accordingly, in this case, an error is displayed by the alarm device 9 installed in the passage 1 to alert the elevator user (ST13).

  Examples of the error display method include a sound alarm such as an alarm device 9 in FIG. 1 and a visual appeal such as an electric bulletin board. Then, by having the user of the elevator again read the information in the IC tag 4 so that the reader 3a, 3b can read the information in the IC tag 4, the inside of the IC tag 4 Read information.

  When it is determined that both of the readers 3a and 3b have read the information recorded on the IC tag 4 (Y in ST11), the read information is received by the receiving unit 6a of the unique information recognizing unit 6. (ST14). The received information is sent to the storage unit 6b and temporarily stored (ST15).

  On the other hand, the information in the IC tag 4 read by the readers 3a and 3b is simultaneously received by the receiving unit 5a of the position information recognizing unit 5 (ST16). Then, the information read by each reader 3a, 3b is compared in the comparison unit 5b (ST17). Here, it is compared whether or not there is a difference in information of each IC tag 4 read by the readers 3a and 3b (ST18). In addition, when the information in each IC tag 4 read by each of these readers 3a and 3b is compared, collated, and determined, each IC tag 4 out of the information recorded in the IC tag 4 is determined. Use the assigned serial number.

  If there is a difference in the information read by the respective readers 3a and 3b as a result of the comparison (Y in ST18), all the information read by all the readers is transmitted to the unique information recognition unit 6 ( ST19). In this case, it means that the plurality of IC tags 4 are read by the readers 3a and 3b. However, any or all of them cannot accurately read all the information in the plurality of IC tags 4.

  For example, it is assumed that three persons A, B, and C carrying the IC tag 4 pass in front of the readers 3a and 3b. In this case, the reader 3a reads information on the IC tags 4a and 4b carried by A and B, and the other reader 3b reads information on the IC tags 4a, 4b and 4c carried by A, B and C. Assuming that the information of the IC tag 4c is not read by the reader 3a, the information of all the IC tags that have passed is read by the reader 3b. That is, there is a difference in the information of the IC tag 4 read by the readers 3a and 3b. Here, for example, when processing is performed in which only the information read by both the readers 3a and 3b (information of the IC tags 4a and 4b) is transmitted to the unique information recognition unit 6, the readers 3a and 3b actually perform 3 Although the information of the two IC tags 4a, 4b, and 4c is read, the information of 4c is not sent to the operation control unit 8 that controls the operation of the elevator 2, which is inconvenient.

  Therefore, in such a case, all the information read by all the readers (in the above example, the IC tags 4a, 4b, 4c) is transmitted to the unique information recognition unit 6. By processing in this way, information can be sent to the operation control unit 8 via the position information recognition unit 5 without dropping any of the read information.

  Next, when there is no difference in the information of the IC tag 4 read by each of the readers 3a and 3b (N in ST18), it is further determined whether or not the information is from the same IC tag 4 ( ST20). As a result, when the information is not from the same IC tag (N of ST20), all the information read by the respective readers 3a and 3b is transmitted to the unique information recognition unit 6 (ST21). Unlike the above case, a plurality of IC tags 4 pass in front of the readers 3a and 3b. However, all the readers 3a and 3b can read the information of the IC tags 4 by the same number of people. Indicates that it was not possible.

  For example, it is assumed that three persons A, B, and C carrying the IC tag 4 pass in front of the readers 3a and 3b. In this case, the reader 3a reads the information of the IC tags 4a and 4b carried by A and B, and the other reader 3b reads the information of the IC tags 4a and 4c carried by A and C. The information of the IC tag 4c cannot be read by the machine 3a, and the information of the IC tag 4b cannot be read by the reader 3b. That is, all the readers 3a and 3b read the IC tag information for the same number of people, but the read IC tag information does not completely match. Here, for example, when a process for transmitting only the information read by both the readers 3a and 3b (information of the IC tag 4a) to the unique information recognition unit 6 is performed, the three ICs are actually used by the readers 3a and 3b. Although the information of the tags 4a, 4b, and 4c is read, as a result, the information of 4b and 4c is not sent to the operation control unit 8 that controls the operation of the elevator 2, which is inconvenient.

  Therefore, in such a case, all the information read by all the readers (in the above example, the IC tags 4a, 4b, 4c) is transmitted to the unique information recognition unit 6. By processing in this way, it is possible to send information to the operation control unit 8 via the position information recognition unit 5 by effectively using the read information.

  On the other hand, it is determined whether or not the information is from the same IC tag 4, and if both are information from the same IC tag (Y in ST20), the information is transmitted to the unique information recognition unit 6. (ST22). In this case, a plurality of IC tags 4 have passed in front of the readers 3a and 3b, and it has been shown that the information of the IC tags 4 for the number of people that all the readers have passed can be read accurately.

  Through any of the above steps (ST19, ST21, ST22), the unique information recognition unit 6 receives the information of the IC tag 4 read by the readers 3a, 3b from the position information recognition unit 5 (ST23).

  By the way, when it is determined that only one of the readers 3a and 3b has read the information of the IC tag 4 (Y of ST12), the read information is received by the receiving unit 6a of the unique information recognizing unit 6. (ST24). The received information is sent to the storage unit 6b and temporarily stored (ST25).

  On the other hand, the information in the IC tag 4 read by the readers 3a and 3b is simultaneously received by the receiving unit 5a of the position information recognizing unit 5 (ST26). However, in this case, since only one of the readers 3a and 3b can read the information of the IC tag 4, the position information recognizing unit 5 is unique without comparing the information as described above. A process of transmitting the received information as it is to the information recognition unit 6 is performed (ST27).

  Information is transmitted from the positional information recognition unit 5 to the unique information recognition unit 6 through the above-described steps. Thereafter, the determination unit 6c of the unique information recognition unit 6 collates the information transmitted from the position information recognition unit 5 with the information of the IC tag 4 from the readers 3a and 3b stored in its own storage unit 6b. (ST28). The unique information recognizing unit 6 also receives the same information as the position information recognizing unit 5 from the IC tag 4, and the information of the IC tag 4 transmitted from the readers 3a and 3b is stored in the storage unit 6b. . Therefore, the information of the IC tag 4 stored in the unique information recognition unit 6 can be associated with the information transmitted from the position information recognition unit 5. Based on this association, the unique information recognition unit 6 determines the relationship between the information in the IC tag 4 and the building usage. That is, for example, based on the information recorded on the IC tag 4, the user determines an area (for example, office floor, entrance floor, floor with a conference room, etc.) in which the user is allowed to enter the building. In addition, the use of the elevator 2, various facilities and facilities until reaching the floor is permitted.

  Then, from the determined information of the IC tag 4, only information necessary for controlling the operation of the elevator 2, for example, information such as the destination floor is selected (ST 29), and the selected information is recognized as unique information. It transmits from the transmission part 6d of the part 6 to the operation control part 8 of the elevator 2 (ST30).

  The operation control unit 8 receives the information (ST31), and controls the operation of the elevator 2 based on the received information (ST32). As a method of this control, for example, a landing call that pushes up and down buttons on the floor outside the elevator 2 is automatically registered, and the destination floor that the user is going to register is also automatically registered. . In addition, there is a method in which the door other than the destination floor stored in the IC tag 4 is not stopped, or the door of the elevator 2 that has been closed is opened for a user who is permitted to use the elevator 2. it can.

  In the present embodiment, the example in which the information in the IC tag 4 carried by the elevator user is read and the information is used for the control of the elevator has been described. However, the information recorded in the IC tag is read by the reader. The apparatus for comparing and determining the information read by the reading and information recognizing unit, or the method thereof, can be applied to other embodiments. Thereby, the information recorded on the IC tag can be read more reliably with a simple configuration.
