Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a management system for entrance and exit (including entry and exit in the present specification), and in particular, to an RFID (Radio Frequency Identification (hereinafter referred to as “RFID”) tag in this specification). The present invention relates to an entrance / exit management system having additional functions.
[0002]
[Prior art]
The conventional entrance / exit management system attaches RFID tags to entrances and exits, and installs RFID antennas, tag receivers, and intrusion detectors at the entrances and exits. A system has been proposed by the present inventors that cancels the detector or disables the detection of the intrusion detector.
[0003]
When the person wearing the RFID tag 50 approaches the entrance G, the management system of the entrance and exit receives the RF signal constantly transmitted from the RFID tag 50 by the antenna 51.
The ID (data) of the RFID tag received by the antenna 51 is sent to a receiver station 54 via a tag receiver 52 connected to the antenna.
The receiver station 54 identifies the ID of the RFID tag 50 and determines whether or not the traffic is permitted. If the traffic is permitted, cancel the intrusion detector 53 or disable the detection of the intrusion detector 53. In this way, the entrance and exit of the person having the RFID tag 50 with the traffic permission ID is automatically permitted, and the person with the RFID tag 50 without the traffic permission ID and the RFID tag 50 are permitted. If a person who does not have an entrance / exit attempts to enter / exit, the intrusion detectors 56 and 57 are activated, and the entrance / exit can be automatically prevented by an alarm, closing a gate, photographing with a camera, or the like. .
[0004]
In this case, the RFID tag 50 needs to constantly transmit an RF signal, and there is a problem in power consumption of the RFID tag 50.
Therefore, an RFID tag 20 shown in FIG. 3 has been proposed by the present inventors and the like. The RFID tag 20 has an infrared receiving section 11 for receiving infrared rays from an infrared transmitting device, and an infrared receiving section 11 for receiving infrared rays received by the infrared receiving section. A position ID discrimination processing unit 12 for identifying the position ID of the infrared transmitting device based on the wavelength, an RF signal conversion processing unit 13 for converting the position ID into an RF signal together with the ID of the tag 1 itself, and a tag An RF signal transmission processing unit 15 for transmitting to the tag receiver 5 via the antenna 14 and the RFID receiving antenna 4 is provided.
[0005]
As shown in FIG. 5, the entry / exit management system using the RFID tag 20 is such that when the tag holder enters the infrared irradiation area A of the infrared transmission device 3a of the corridor 6 outside the room 8, the tag 20 Receives the infrared light, recognizes the position ID of the infrared transmitting device 3a from the wavelength of the infrared light, converts it into an RF signal together with the ID of the tag 20 itself, and transmits the RF signal.
On the other hand, the tag receiver 5 receives the radio wave from the tag 20 by the RFID receiving antenna 4, recognizes the position ID and the tag ID of the infrared transmitting device 3a, and transmits them to the receiver station (not shown). .
As described above, it is possible to know that the tag holder exists in the irradiation area A of the outside infrared ray transmitting device 3a.
[0006]
At this time, as described above, the entrance and exit are automatically prevented by the alarm, the closing of the gate, the photographing by the camera, etc., and the door 7 provided in the entrance 2 so as to allow the passage of the person having the traffic permission ID. To release.
Further, when the tag holder enters the irradiation area B of the inner infrared transmitting device 3b, it is understood that the tag holder exists in the irradiation area B of the inner infrared transmitting device 3b by the same principle as described above. The receiver station can determine that the tag holder has entered the room at the same time (for example, see Patent Document 1).

[Problems to be solved by the invention]
By the way, in this case, although the unified management of the entrance and exit is possible, the RFID tag only transmits one kind of fixed ID information individually and cannot manage other additional information. Unless infrared rays from the infrared transmitter are received, an RF signal cannot be transmitted, and a signal cannot be transmitted in an emergency.
[0009]
The present invention has been made in view of the above-mentioned problems of the conventional entry / exit management system, and has been made so as to be able to manage not only permission / non-authorization of entry / exit into / out of the facility, but also work time and transmission of emergency situations, etc. The purpose of the present invention is to provide a management system.
[0010]
[Means for Solving the Problems]
To achieve the above object, the entrance / exit management system of the present invention attaches an RFID tag to the entrance / exit, and arranges an infrared ray, a sound wave or a radio wave transmitting device at the entrance and exit, and a tag receiver, In a management system in which a tag manages visitors by transmitting the ID of the tag itself to the tag receiver together with the position ID of the transmitting device based on the characteristics of the received infrared ray, sound wave, or radio wave, the tag is individually controlled by pressing a switch. It is characterized in that entrance / exit management is performed using an RFID tag for transmitting an ID.
[0011]
The entrance / exit management system can be used as emergency information in the case of adding or leaving work to / from a workplace by using ID information transmitted by pressing a switch separately from ID information of the tag itself.
[0012]
In this case, entry and exit can be managed by using an RFID tag that includes a plurality of switches and can transmit different signals by pressing them in combination.
[0013]
Thereby, a plurality of pieces of ID information can be transmitted by a combination of pressing of the switches.
[0014]
In this case, the entry and exit can be managed by using an RFID tag capable of transmitting the ID of the tag itself for a certain period of time by pressing a plurality of switches in an arbitrary order.
[0015]
Thereby, depending on the lost RFID tag, the ID of the tag itself is not transmitted, and illegal entry can be effectively prevented.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of an entrance / exit management system according to the present invention will be described with reference to the drawings.
[0017]
FIG. 1 and FIG. 2 show an RFID tag used in the entrance / exit management system of the present invention.
Similar to the conventional RFID tag, the RFID tag 1 has an infrared receiver 11 for receiving infrared rays from the infrared transmitters 3a and 3b, and a position ID of the infrared transmitter based on the wavelength of the infrared light received by the infrared receiver. A position ID discrimination processing unit 12 for discriminating, and an RF signal conversion processing unit 13 for converting the position ID into an RF signal together with the ID of the tag 1 itself, and a switch ID for discriminating depression of a switch in conjunction with a switch on the front surface A determination processing unit 16 is provided, and an RF signal transmission processing unit 15 for transmitting the converted RF signal to the tag receiver 5 via the tag antenna 14 and the RFID receiving antenna 4 as in the conventional example.
[0018]
In a state where the switch is not normally pressed, the RFID tag 1 emits infrared rays, sound waves, or radio waves (hereinafter, referred to as infrared rays) from an infrared ray, a sound wave, or a radio wave transmitting device (hereinafter, referred to as infrared ray transmitting devices 3a and 3b as in the related art). Will be described) when the infrared receiving section 11 of the tag 1 receives it, converts it into an RF signal together with the individual ID of the RFID tag 1 itself and the position ID determined by the received infrared ray, and transmits a radio wave. When the tag receiver 5 determines the position ID and the individual ID, grasps the position of the tag holder, and receives the title-specific individual ID, In the same manner as in the conventional example, the passage gate is opened to control entry and exit.
[0019]
At this time, when a function of the switch A provided in the RFID tag 1 is given, for example, a departure declaration ID and a function of the switch B is given a departure declaration ID, the switch A or the switch B is depressed to enter and leave the room. Then, the same effect as when a time card is pressed can be obtained.
[0020]
In addition, when a patient or the like admitted to a hospital is provided with a tag, by giving an emergency ID to one of the switches, it is possible to notify an emergency no matter where one is in the hospital.
[0021]
Further, in the case of the RFID tag 1 having an ID function start switch function, the individual ID is transmitted by, for example, combining the pressing order of three switches A, B, and C, and It should be possible to transmit only for a certain period of time after the button is pressed (in the case of 8 hours according to the working hours of the day, or in the case of the purpose of improving security due to loss, set to a short time of about 2 hours). Thus, it can be prevented from being used by others due to loss or the like.
[0022]
In addition, it is possible to configure so that different signals are transmitted by simultaneously pressing a plurality of switches.In particular, when entering a room requiring security, in addition to the individual ID, simultaneous pressing of the switches and the order of pressing the switches can be performed. The combination may allow only those who have transmitted the correct signal to pass.
[0023]
As described above, the entrance / exit management system of the present invention has been described based on the embodiment. However, the present invention is not limited to the configuration described in the above embodiment, and may be appropriately changed without departing from the gist thereof. The configuration can be changed.
[0024]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to the entrance / exit management system of this invention, in addition to giving an individual ID signal to an RFID tag, an emergency situation can be reported by pressing a switch, and the working time changed to a time card can be managed.
[0025]
In addition, when the function of transmitting the individual ID signal of the RFID tag is made effective for a certain period of time by a combination of pressing the switches, it is possible to prevent an outsider who has acquired the RFID tag from getting into the room due to loss.
