Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a position detection system used to locate and identify a person entering or exiting a room.

[Conventional technology]

2. Description of the Related Art Intruder alarm devices have been widely used in corporate offices, houses, and the like to detect intrusion of people into work areas or living areas, and issue an alarm accordingly. This intruder alarm system installs an infrared emitter and an infrared receiver at entrances where people can easily move, and detects when an intruder crosses the infrared beam from the infrared emitter, that is, the beam is interrupted. and one in which an alarm is issued from an alarm device based on the output of the above-mentioned infrared receiver,
A proposed system is one in which a personal identification card carried by an individual is identified by a personal identification card reading device installed at the entrance, and an electric lock is locked or unlocked according to the identification result, allowing only specific individuals to pass through and enter. has been done.

[Problem to be solved by the invention]

However, such conventional human intrusion alarm systems using infrared emitters and infrared receivers are sufficiently effective when used for security against intrusion at night when unattended, but when a large number of people enter and exit, Intrusion is detected and an alarm is issued by both authorized and unauthorized persons, making it ineffective for use in areas where people move frequently.

In addition, intruder alarm devices that read personal identification cards using personal identification signal reading devices distinguish between those who are allowed to enter and exit and those who are not, so they can correctly identify intruders who are not allowed to enter or exit. However, if a person who is not authorized to enter follows the door of a population that has been opened by a person who is permitted to enter and exit, this will be overlooked and the door will be closed once the intruder has entered. There was a problem that once the intrusion occurred, the situation after the intrusion could not be grasped at all.

In addition, a fingerprint detector was installed at the entrance of the room, and permission to enter and exit was granted after comparing the fingerprint on the personal identification card with the fingerprint registered in the fingerprint detector. However, in this case, the cooperation of the examinee is required, just as when using a normal personal identification card.

Furthermore, when using a personal identification card as described above,
When trying to detect this without contact, it is necessary to close the detector to the detection part within a certain distance, which poses problems such as making it difficult to put it into practical use.

This invention was made in view of the above-mentioned problems in the prior art, and uses footwear such as shoes to emit a personal identification signal, which is detected by a signal reading device laid flat on the floor. An object of the present invention is to obtain a position detection system that can automatically and reliably identify the location of a person and the person.

[Means to solve the problem]

In the position detection system according to the present invention, a personal identification signal generating device is attached to footwear, and a signal reading device is provided on the upper or lower surface of the floor to capture the output signal emitted by the personal identification signal generating device. The structure is such that the data processing device identifies the person wearing the footwear and the location of the person based on the signal.

[Effect]

The personal identification signal generating device according to the present invention includes, for example, a barcode cart having an optical structure or a magnetic structure, which passes over a signal reading device made of, for example, an electromagnetic induction wire or a photocoupler laid in a matrix on the floor. As they move, they optically or magnetically detect the location of the barcode-card and the ID code on the barcode. Therefore, by processing this detected detection data, it is possible to determine the location in the room of a person wearing shoes equipped with a barcode card attached with a display device such as a sound generator or a display device such as a message using a liquid crystal display. It is possible to easily determine who the person is by calculation.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a signal reading device installed at regular intervals on the underside of the floor.
Consists of a matrix of parallel wires arranged around 0 mm.
The intersection position of each of these conductors IA corresponds to a detection position on the floor. Each of these conductors IA outputs a predetermined voltage in response to the magnitude of magnetism, and when a personal identification card as a personal identification signal generator having a magnetic material with a barcode pattern, which will be described later, approaches the conductor IA. By moving the personal identification card, a pulse signal corresponding to the bar code pattern is induced to the conductor IA near the personal identification card.

2 is a data processing device which introduces the induced pulses from each of the conductors IA, and from this determines the position of the person on the floor, which is the location of the personal identification card, and the identity of a particular individual, which is the content data of the personal identification code. Performs arithmetic processing to obtain data. 3 is a display device that displays the processing results of the data processing device 2;

FIG. 3 shows a shoe 5 having a personal identification card 4 as a personal identification signal generating device for identifying a specific individual according to the present invention. The shoes 5 may be made of leather, resin, or rubber, and the personal identification card 4 is attached to a part of the sole that does not directly touch the floor. This personal identification card 4 has a barcode pattern of a magnetic material for personal identification that specifies the individual wearing the shoes, and this barcode pattern is attached to any of the above-mentioned conductors IA. When passing near the
A barcode pulse signal corresponding to the barcode pattern is induced into the conductor at the passage point. Incidentally, the personal identification card 4 may be attached to the side surface or instep of the shoe 5, as shown by the chain line in FIG.

Further, the attachment of the personal identification cart 4 to the shoes 5 can be secured by using a holder 6, in addition to bonding with an adhesive or the like, either independently of this bonding or in conjunction with this bonding.

In a position detection system having such a configuration, for example, a personal identification card 4 owned only by a person who is allowed to enter a certain room is attached to the shoes 5 worn by that person, as shown in FIG. Therefore, this person, as shown in Figure 2,
When the person opens the door and enters the room, the conductor IA at the position of the shoes 5, that is, the position closest to the personal identification card 1-4, is connected to the conductor IA according to the barcode pattern of the magnetic material of the personal identification card 4. A pulse signal is induced. and,
This induced pulse is input to the data processing device 2, which performs various identification processes for the position of the personal identification card 4 on the floor and the holder of the personal identification card 4, that is, the individual identified by the personal identification card 4. , the result is displayed on the display device 3
will be displayed.

However, if a person who does not wear the personal identification card 4 on his shoes enters the room, no signal for identifying that specific individual will be guided to the conductor IA, so in this case The data processing device 2 can also activate the alarm device 6 to warn of illegal intrusion by a foreigner.

In the above embodiment, data from the personal identification cart 4 is read using electromagnetic induction. However, a large number of light sources such as light emitting diodes are placed on the floor according to a certain rule, and a bar is placed above the light source. Also by moving a personal identification card with a mirror of the code pattern.

The position of the shoe with the mirror barcode for individual identification and each identification process of the specific individual can be detected using optical means in the same manner as in the above embodiment.

Further, in the above embodiment, the conductor IA is provided on the lower surface of the floor, but the floor may be a carpet, a wooden board, or a synthetic resin board that does not contain magnetic material.

Furthermore, in the embodiment described above, the personal identification card 4 is attached to the shoe 5.
Although we have explained the case of attaching the personal identification card 4, it is also possible to use the personal identification card 4 by attaching it to general footwear such as slippers. By asking customers to do this, it becomes possible to grasp the customer flow line 8 moving toward the display s7, as shown in FIG. 4, and it is also possible to automatically manage best-sellers.

In addition, the personal identification card 4 is converted into an IC card, and its IC
By equipping the circuit with transmitting and receiving functions.

It is also possible to transmit a contact signal from the center to a specific individual by voice or light.

〔Effect of the invention〕

As described above, according to the present invention, a personal identification signal generating device is attached to footwear, and a signal reading device is provided on the upper or lower surface of the floor to capture the output signal generated by the personal identification signal generating device.

Based on this output signal, the data processing device is configured to identify the person wearing the footwear and the location of the person, so personal identification data can be detected with high sensitivity. Therefore, it is possible to continuously, accurately and automatically identify the status of people entering and exiting the room and the identification of the person, and it is possible to achieve effects such as eliminating errors in the identification work.

Further, when a conductive wire is used as a signal reading device laid on the floor surface, the equipment cost can be reduced and practicality can be increased.
