Description

  The present invention relates to an entry / exit management support system that supports ID data wirelessly transmitted by an ID card such as an IC card by a wireless card reader and controls door unlocking to perform entrance / exit management.

  In recent years, entrance / exit management systems that control door unlocking have been adopted in office buildings and luxury condominiums. The entrance / exit management system reads ID data (identity data) of an authentication card (ID card) with a wireless card reader and collates it with management data, and manages unlocking of the door based on the collation result. A wireless ID chip for transmitting ID data wirelessly is embedded in the ID card.

  In office buildings and high-end condominiums that require a high level of security, the identity of the user is determined using a fingerprint, retina, etc. before the user enters or leaves the room using an ID card, and the revolving door is passed. This is to surely prevent a suspicious person from entering the room due to unauthorized take-in. This is described, for example, in Patent Document 1 below.

JP 2004-197455 A

  In the conventional technology, in order to prevent the suspicious person from entering the room, personal authentication is performed twice like fingerprint authentication and card authentication, and further restrictions imposed by physical block gates such as revolving doors and electromagnetic locks are imposed. The problem is that the user's psychological burden increases. In particular, in high-end condominiums, forcing such users to have a psychological burden is downgrading. For this reason, development of the technique which can prevent a suspicious person's entrance easily without giving a psychological burden to a user is strongly desired.

  An object of the present invention is to provide an entrance / exit management support system that can easily prevent a suspicious person from entering a room without giving a psychological burden to the user.

  A feature of the present invention is that a setting area is provided in an entrance passage through which a user passes, and a user who passes through an entrance boundary area on an entry side and an exit boundary area on an exit side is photographed with a camera. At the same time, the ID data permitted from the ID card carried by the user present in the setting area is received, and the number of users existing in the setting area counted by the images taken by both cameras and the number of users based on the ID data. And when there is a discrepancy, it is determined that there is a suspicious person.

  Since the present invention determines the suspicious person by comparing the number of users existing in the setting area counted by the captured images of both cameras and the number of users based on the ID data, the suspicious person is not given a psychological burden on the user. Can be prevented easily.

  The user carries an ID card that transmits the ID data of the user himself / herself. The ID card is embedded with a wireless ID chip that transmits ID data wirelessly. A setting area is provided in an entrance passage through which a plurality of users pass. In the setting area, an entrance boundary area perpendicular to the entrance passage is set on the entry side, and an exit boundary area is set on the exit side. The first camera photographs a user who passes through the entrance boundary area, and the second camera captures a user who passes through the exit boundary area. The wireless card reader receives permitted ID data from an ID card carried by a user existing in the setting area. The monitoring controller compares the number of users present in the setting area counted by the images taken by both cameras with the number of users based on the ID data received by the card reader, and determines that there is a suspicious person if they do not match. The monitoring controller calculates the number of users existing in the setting area by subtracting the number of persons leaving the setting area from the number of persons entering the setting area from the captured images of both cameras.

  FIG. 1 shows an embodiment of the present invention. FIG. 1 shows an example of a luxury apartment.

  In FIG. 1, a monitoring area (setting area) 3 is provided in an entrance passage 2 leading to an automatic door 1. In the setting area 3, an entry side boundary area 3a perpendicular to the entrance passage 2 is set on the entry side, and an exit side boundary area 3b is set on the exit side (automatic door 1 side).

  A user 4 passing through the entrance passage 2, that is, the setting area 3 carries an ID card 5 that transmits the ID data of the user himself / herself. The ID card 5 is embedded with a wireless ID chip (RFID) that transmits ID data wirelessly. Although a plurality of users 4 pass through the setting area 3, only one person is illustrated.

  The first camera 6 photographs the user 4 passing through the entrance boundary area 3a, and the second camera 7 captures the user 4 passing through the exit boundary area 3b. The wireless card reader (wireless tag reader) 8 receives the permitted ID data from the ID card 5 carried by the user 4 existing in the setting area 3. The card reader 8 counts the number of RFIDs (number of users) that transmit permitted ID data. The cameras 6 and 7 and the card reader 8 are installed on the ceiling of the entrance passage 2.

  The monitoring controller 9 inputs the number of users based on the captured images of both cameras 6 and 7 and the ID data received by the card reader 8. A personal computer is used as the monitoring controller 9. The number of users existing in the setting area 3 counted by the captured image is compared with the number of users based on the ID data received by the card reader 8. judge.

  FIG. 2 shows an example configuration diagram of the monitoring controller 9. The monitoring controller 9 includes a central processing unit (CPU), a bus (BUS), a work memory (MEM), a program memory (ROM), a display (DSP), a keyboard (KB), a voice alarm device (SP), cameras 6 and 7. The image input interface (A / D) and the card reader 8 interface (SIO).

  Next, the operation will be described with reference to the flowchart shown in FIG.

  In step S <b> 1, the monitoring controller 9 clears the number of detected RFIDs and the number of users (the number of staying people) existing in the setting area 3. In step S2, the RFID in the setting area 3 is read, and it is determined whether the RFID is permitted in step S3. If it is determined in step S3 that the RFID is permitted, the process proceeds to step S4 to increase the number of detected RFIDs.

  In step S5, it is determined whether all RFIDs have been read. If the reading is completed, all the RFID numbers in the setting area 3 are detected. If it is determined in step S5 that reading of all RFIDs has not been completed, the process returns to step S2 and the process is repeated.

  If it is determined in step S5 that all RFIDs have been read, the number of people staying in the setting area 3 is calculated in steps S6 to S8. In step S6, an image is captured from the camera 7 that captures the outgoing boundary area 3b, and the number of people entering and leaving the setting area 3 is calculated. The number of inbound persons is the number of persons calculated from the motion vector of the user 4 who has moved from the left side to the right side of the outgoing boundary area 3b, and the number of inbound persons is the number of persons calculated from the motion vector in the opposite direction.

  From step S6 to step S7, an image is captured from the camera 6 that captures the entry-side boundary area 3a, and the number of persons entering and leaving the setting area 3 is calculated. The number of inbound persons is the number of persons calculated from the motion vector of the user 4 who has moved from the right side to the left side of the inbound boundary area 3a, and the number of inbound persons is the number of persons calculated from the motion vector in the opposite direction.

  In step S8, the sum of the number of inbound persons and the number of inbound persons determined in steps S6 and S7 are obtained, and the difference between the two is calculated. That is, “(sum of the number of people entering the area) − (sum of the number of people leaving the area)” is calculated. The number of users 4 in the setting area 3 is equal to the number obtained by subtracting the number of retired persons from the number of persons entering the outgoing boundary area 3a and the incoming boundary area 3b.

  In step S9, it is determined whether the number of detected RFIDs and the number of uses determined from the camera image do not match. If they do not match, it is determined that there is a suspicious person and an audio alarm is output in step S10. With this voice alarm output, the guards will rush to respond. When there is a suspicious person, the door 1 can be prevented from being opened by being physically interlocked with the automatic door 1.

  In this way, the suspicious person is monitored, but the present invention determines the suspicious person by comparing the number of users existing in the setting area counted by the images taken by both cameras and the number of users based on the ID data. Therefore, it is possible to easily prevent the suspicious person from entering the room without giving a psychological burden to the user.
