  That is, an entrance / entrance management apparatus that opens an entrance gate or a room door by allowing an ID card to be read by a reader when entering or entering a room and confirming that the person is a registered person has become widespread. This guarantees the security of the building.

  However, before the gates and doors are closed, those who do not have an ID card may be confused by those who are authorized to enter and enter the room. Alternatively, it may be assumed that a person who has been authorized to enter and enter the room has the purpose of intentionally bringing a person who has not received permission. A state in which a person who has not received such permission authentication is accompanied by a person who has received permission to enter and enter the room is called a co-entry room.

  In such a case, there is a concern that normal security management is not performed and many crimes occur.

  As a prior art relating to entrance management, the invention described in Patent Document 1 places at least two sensors in the passing direction of a passing person and counts the number of passing persons.

  The invention described in Patent Document 2 detects a passing person and measures the number of people passing by the time passing in front of the two-type optical sensor.

  The invention described in Patent Document 3 eliminates the hassle of personally authenticating all the groups when a group of a plurality of people enter the building, and improves convenience when entering the building. The number of people who pass is entered, and only one personal authentication allows the entire group to enter the building.

  The invention described in Patent Document 4 determines an entry / exit state based on detection outputs of both a non-contact card reader and a sensor for detecting a person.

In the invention described in Patent Document 5, the gate (or door) is opened / closed based on the coincidence / mismatch between the number of RF-ID tags read from the RF-ID tag and the number of persons in a limited input / output location. It is something to control.

  Embodiments will be described below with reference to the drawings. The embodiments are for understanding the invention, and the application of the invention is not limited to the embodiments.

  FIG. 1 is a diagram for explaining an outline of entrance / exit management to which an entrance management apparatus according to the present invention is applied.

  A control system of an entrance management device is arranged in the building 100.

  The control system includes the introductory management device 10 as a main device. A gate opening / closing device 11 is connected to the entrance management device 10, and the gate opening / closing device 11 opens and closes the entrance gate (or door) 12 of the building 100 based on a control signal from the entrance management device 10.

  The introductory management device 10 is connected to a reading device 13 that performs bidirectional communication with a remote controller (portable device) 20 possessed by the introductory person, performs mutual authentication, and outputs the result.

  Further, the control system has a person counting device 14 and counts the number of persons in the area of the introductory gate 12. Various methods can be applied to the people counting function of the people counting device 14.

  For example, when it is sufficient to detect that at least a plurality of people are in the area of the introductory gate 12, this can be detected by an infrared sensor.

  Alternatively, the number of persons can be measured by recognizing a face pattern using digital image recognition technology and counting the number of recognized face pattern frames.

  In the room entrance management apparatus shown in FIG. 1, the remote controller 20 is registered in advance in the entrance management apparatus 10.

  When a person who owns the remote controller 20 tries to enter the building 100, the person approaches the building 100 and transmits a call signal from the remote controller 20 following the preamble signal.

  The reading device 13 detects the preamble signal, and sends an identification code transmission request to the remote controller 20 together with the identification code of the entry management device 10. The remote controller 20 authenticates the identification code of the introductory management device 10 and transmits the identification code of the remote controller 20.

  On the other hand, the reading device 13 receives the identification code of the remote controller 20 and sends it to the entry management device 10.

  The entrance management device 10 checks the identification code of the remote controller 20 registered in advance, and if it matches, the entrance management device 10 relates to the number of people entering the room (passing through the entrance gate) from the remote controller 20 for the control to open the subsequent gate. Receive a signal.

  FIG. 2 is an example of the remote controller 20 and shows an appearance. The remote controller 20 has a wireless authentication function.

  A set button 201a, a reset button 201b, a number of people input button 202, and a number of people display section 203 are provided. The number of people input button 202 has a button 202a for inputting the number of people “1” by default and a number of people increasing button 202b for increasing the number of people by “1” each time the button is pressed.

  When the above-described mutual authentication is performed between the remote controller 20 and the reader 13, the remote controller holder inputs the number of persons entering the room using the number input button 202 (202a, 202b) and presses the set button 201a. The number of persons can be transmitted to the reading device 13. The reset button 201b is used to cancel the alarm.

  On the other hand, when the remote control holder intends to enter the room and approaches the building 100, the remote control holder enters the person counting area 30. In this people count area 30, the number of people in the people count area 30 is detected by an infrared sensor as shown in FIG.

  FIG. 3 is a diagram for explaining an example of the sensor device in the people count area 30.

  The sensor device includes a horizontal sensor 30a and a vertical sensor 30b.

  The horizontal direction sensor 30 a is an infrared sensor placed at a predetermined distance from the entrance gate 12 of the building 100. When a person holding the remote controller 20 that has performed mutual authentication approaches from the entrance gate 12 to a predetermined distance, infrared rays reflected from the person are detected.

  On the other hand, the vertical sensor 30 b has an infrared sensor on the ceiling, and detects infrared rays reflected from a person approaching the building 100.

  Here, since the human shoulder width is about 40 to 65 cm for an adult, the shoulders are arranged on the ceiling at intervals of 10 cm.

  Then, the state detected by these sensor devices is sent to the person counting device 14.

  FIG. 4 is a functional block diagram illustrating functions of the introductory management apparatus 10, and FIG. 5 is a corresponding functional processing flow.

  Here, in FIG. 4, the accompanying detection device 140 is shown as including a person counting device 14, a horizontal direction sensor 30 a, and a vertical direction sensor 30 b.

  Further, the remote controller 20 and the reading device 13 form a wireless authentication system. For example, a wireless authentication system (Japanese Patent No. 293276) based on mutual authentication previously presented by the present inventors can be applied.

  That is, in the wireless authentication system based on mutual authentication described in Japanese Patent No. 293276, the remote controller 20 and the reading device 13 register each other's identification ID in advance in the own device and transmit the identification ID to each other. Then, it is determined whether the identification ID transmitted from the other party matches the identification ID registered in advance in the own device. Then, when the identification IDs match in the determination in both devices, mutual authentication is established and data can be transmitted and received. Such mutual authentication can ensure high security.

  In the function processing flow of FIG. 5, such mutual authentication is performed, and the number of people entering the room is notified (step S1).

  Here, as a first example, a case is assumed in which only the remote control holder is allowed to pass through the entrance gate to prevent sharing. In such a case, the number of people entering the room is notified as “1”.

  First, the passage of a person is detected by the horizontal sensor 30a (step S2). Next, measurement of the number of people is started (step S3).

  It is determined whether the number of sensor detections detected by the vertical sensor 30b per unit time, for example, 1 second is 7 or less continuously (step S4). That is, the person counting device 14 of the accompanying detection device 140 sets a detection timing a plurality of times per second, records the detection signal from the vertical direction sensor 30b, and measures the number of times of continuous detection.

  When the number of times of sensor detection is 7 or less consecutively (step S4, Yes), the person counting device 14 notifies the entrance management device 10 that one person is going to enter the entrance gate 12. (Step S5). On the other hand, if the number of sensor detections is continuously greater than 7 (step S4, No), the entrance management device 10 is notified that there are a plurality of persons trying to enter the entrance gate 12 (step S6). .

  The introductory management device 10 receives the notification from the people counting device 14, and determines whether or not the notified number of people matches the number of people reported (step S7).

  When it is notified by the coincidence determination circuit 101 that one person is going to enter the room, it is determined as coincidence. In this case, the gate opening / closing device 11 is controlled to open the entrance gate 12 (step S8).

  On the other hand, if the coincidence determination circuit 101 determines that there is a mismatch, the gate opening / closing device 11 is controlled to close the entrance gate 12 (step S9).

  Thereby, those who pass through the introductory gate 12 with a companion other than the owner of the remote control can be blocked.

  Further, when the coincidence determination circuit 101 determines that there is a mismatch, corresponding processing such as sounding the alarm device 15 or notifying the administrator through the management device is performed.

  Furthermore, as a second example, when a plurality of persons together with the remote control owner try to pass the entrance gate 12, the number of persons entering the room is not “1” but the corresponding number of persons entering the room is notified.

  Therefore, the number counting device 14 of the accompanying detection device 140 obtains an average value of the number of people detected by the vertical direction sensor 30b at every detection timing a plurality of times per second. Then, the coincidence determination circuit 101 compares the average value of the number of persons obtained by the number counting device 14 with the number of persons previously notified by the remote control owner.

  If the difference is within the predetermined value as a result of the comparison, it is determined that the number of beginners is as reported, and the gate opening / closing device 11 is controlled to open the entrance gate 12 (step S8).

  As described according to the above-described embodiment, the present invention appropriately manages room entry, which leads to suppression of violent crimes and the like that have frequently occurred in recent years.

  Even in auto door lock apartments, there are always suspicious students who are introduced after the residents. By using the technique of the present invention, it is possible to detect the person entering with the resident and control so as not to open the gate, or at the same time automatically notify the administrator, so that the following measures can be taken.

It is a figure explaining the outline | summary of the entrance / exit management which applies the entrance management apparatus according to this invention. It is an example of the remote controller 20 and is a diagram showing an appearance. FIG. 3 is a diagram for explaining an example of the sensor device in the people count area 30. 3 is a functional block diagram illustrating functions of an introductory management device 10.
