For example, when the number of successes is 100, the estimated distance is 0, when the number of successes is 50, the estimated distance is L, and when the number of successes is 25, the estimated distance is 2L.
- Such data can be created by taking statistics of the number of successes while changing the distance between the wireless IC tag 20 and the reader Z writer 30, but even if such data is created by other methods. OK!
- FIG. 11 shows an example of a table that stores the result of the motion analysis unit 103 calculating the estimated position of the wireless IC tag 20 based on the estimated distance for which the number of success times force is calculated.
- This table 110 has one record 1101 for each unique ID.
- Each record 1101 has a unique ID field 1102 for storing a unique ID, a first estimated distance field 1103 for storing an estimated distance from reader / writer A, and a second estimated distance field 1104 for storing an estimated distance from reader Z writer B.
- an estimated position field 1105 for storing the estimated position of the wireless IC tag 20 corresponding to the unique ID.
- the estimated position stored in estimated position field 1105 is calculated by motion analysis section 103 based on the estimated distances stored in first estimated distance field 1103 and second estimated distance field 1104.
- FIG. 12 is a conceptual diagram of a method for calculating an estimated position based on the estimated distances stored in the first estimated distance field 1103 and the second estimated distance field 1104.
- two reader / writers A and B are provided in a certain space (for example, a warehouse) 1200.
- the position of leader Z writer A is point P
- the position of reader Z writer A is point Q.
- the estimated distance between a wireless IC tag 20 and a reader Z writer A is L1
- the estimated distance force between the wireless IC tag 20 and the reader Z writer B is L1
- this wireless IC tag exists on a circle 1201 having a radius L1 centered on the point P and satisfying a circle 1202 having a radius L2 centered on the point P. That is, the estimated position of the wireless IC tag 20 can be obtained by obtaining the intersection of the circle 1201 and the circle 1202.
- the estimated position is not necessarily coordinate information, and information that specifies an area having a certain extent (for example, individual sections obtained by dividing a space into 16 sections) is used as the estimated position. Also good. In the example shown in Figure 12, there are two intersections, so the coordinates must be uniquely determined. I can't. In such a case, an area including these two intersections may be set as the estimated position.
- the estimated position calculated as described above is stored in the estimated position field 1105 of each record 1101.
- the motion analysis unit 103 can calculate an estimated position for each unique ID by referring to the table 110, and can calculate an estimated position of each wireless IC tag 20 and an exercise situation based on the estimated position. It becomes possible.
- the estimated distance is determined based on the number of successes. However, even if the estimated distance is determined based on the success probability (success number of times Z total number of read processing times), The invention is valid.
- An authentication means for performing biometrics authentication may be added to the above-described entrance / exit management system 1. For example, when the holder of the wireless IC tag 20 has reached the point just before the passing point, biometrics authentication for fingerprints, veins, faces, irises, etc. is performed, and only when the biometrics authentication is successful, the above-mentioned figure 8 Thus, the driving of the passage control device 40 in step S811 is executed. By deforming in this way, it is possible to prevent a person who has illegally acquired the wireless IC tag 20 (picked up or stolen) from entering the management target area illegally.
- Artificial voice generation means may be further added to the entry / exit system so that various messages and warnings may be issued in the execution of the entry / exit management method. For example, if the wireless IC tag holder 202 remains in the vicinity of the passing point and the driving control device 40 cannot be driven, a message such as ⁇ I'm afraid, please move away from the passing point immediately '' is displayed. You may make it emit by artificial voice. Also, if the wireless IC tag holder 201 or the wireless IC tag holder 202 is rapidly approaching the passing point and there is a risk of collision, a message such as “Dangerous. You can make a sage with artificial voices!
- the entry / exit management system and the entry / exit management apparatus manage whether or not entry / exit through a passing point is possible based on identification information obtained by reading identification information storage medium power.
- identification information obtained by reading identification information storage medium power.
- the entrance / exit management system operates and opens the door etc. by determining whether or not it is possible to pass the passage point, a third party gets into the machine and enters And has industrial applicability.
