Description

  The present invention relates to an entry / exit management system that includes a lock mechanism that automatically locks and unlocks a door of an entrance, and manages entry / exit of the authorized person in a room that is permitted only to the authorized person.

  For example, companies, research institutions, and the like are provided with an entrance / exit management system that allows only authorized personnel, such as employees, to enter a specific room, in order to maintain confidentiality. For example, Patent Document 1 discloses the following entrance / exit management system. That is, this system includes an entrance side card reader and an exit side card reader provided on the entrance side and the exit side of the room, an electric lock provided on the door, a door open detection sensor for detecting that the door is opened, It consists of a controller that controls the whole. The authorized person who is allowed to enter the room has an ID card, and ID information of the authorized person registered in advance is registered in the controller.

Thus, when the ID card is read by the entrance side card reader and the collation is OK, the controller unlocks the electric lock and then detects that the door is opened by the door opening detection sensor. The entry of the authorized person is recorded (flag is set to 1). Then, when the ID card is read by the exit side card reader and the collation is OK, the electric lock is unlocked, and then the door open detection sensor detects that the door is opened. It is determined that the user has exited (the flag is set to 0). Further, the controller turns off the power to the room lighting equipment and air conditioning equipment when it is determined that the room is unmanned.
JP-A-2-309499

  By the way, in the entrance / exit management system as described above, the entrance / exit of a person is determined based on the opening / closing of the door after the entrance / exit operation (card reading operation). However, for example, the person who wants to enter the room opens the door by entering the room, but the situation changes during that time and the person does not actually enter the room. Is also possible. In such a case, the inconvenience that it becomes impossible to grasp the person's accurate entrance / exit (the number of people in the room) occurs.

  Therefore, in order to deal with such a problem, in the above-mentioned Patent Document 1, a human sensor for detecting the presence of a person in the room is provided, and the controller determines that all have left (all the flags are 0). In addition, it is determined that the room is unattended on the condition that the human sensor detects unattended. However, in the above prior art, it is necessary to provide an extra human sensor, which increases the cost accordingly. In particular, in the case of a large room, there are circumstances in which a large number of human sensors must be provided so that there are no blind spots.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an entry / exit management system that can determine a person's entry / exit without fail, but can be completed with an inexpensive configuration. .

  In order to achieve the above object, an entrance / exit management system of the present invention includes an entrance-side authentication terminal that is provided outside the entrance near the entrance and performs an authentication operation of an authorized person permitted to enter the room, and a room near the entrance / exit. An exit-side authentication terminal that is provided inside and performs an authentication operation of the authorized person, and an entrance door by the lock mechanism based on the confirmation of the authorized person by the authentication operation of the entrance-side authentication terminal or the exit-side authentication terminal A lock release control means for executing unlocking, a door open / close detection means for detecting opening / closing of the door, and a judgment means for judging entry and exit of the authorized person. The authorized person is confirmed by the authentication operation of the authentication terminal, and the door opening / closing detection means is detected by the door opening / closing detection means after unlocking by the lock release control means, and then the exit side authentication is detected. When the same authorized person is confirmed by the authentication operation of the terminal, it is determined that the authorized person has entered the room, the authorized person is confirmed by the authentication operation of the exit side authentication terminal, and the lock by the unlock control means associated therewith When the door opening / closing detection means is detected after the release, and the same authorized person is confirmed by the authentication operation of the entrance side authentication terminal, it is determined that the authorized person has left the room. However, it has characteristics (the invention of claim 1).

  In the above configuration, when the authorized person enters the room, the authentication operation is first performed by the entrance-side authentication terminal, and when it is confirmed that the authorized person is authorized, the unlocking control means unlocks the door. Thereby, the authorized person can enter the room by opening the door, and the opening / closing of the door at that time is detected by the door opening / closing detection means. Next, the authorized person is judged by the judging means that the authorized person has entered the room by performing the authentication operation by the exit side authentication terminal. As a result, it is determined that the authorized person actually enters the room and enters the room only after being confirmed as the same authorized person by the authentication operation of the exit side authentication terminal. If the authentication does not match, the door remains locked, so that an unauthorized person cannot enter the room.

  Similarly, when an authorized person staying in the room leaves the room, first, the authentication operation by the exit side authentication terminal is performed, and if it is confirmed that the person is authorized, the lock release control means locks the door. Release is performed. Thereby, the authorized person can leave the room by opening the door, and the opening / closing of the door at that time is detected by the door opening / closing detection means. Next, the authorized person is judged by the judging means that the authorized person has exited by performing the authentication operation by the entrance side authentication terminal. As a result, it is determined that the authorized person who has been in the room has actually exited and has exited only after being confirmed as the same authorized person by the authentication operation of the entrance-side authentication terminal.

  As a result, it is possible to reliably determine the entry / exit of the authorized person by performing the authentication operation twice each when entering the room and leaving the room. In this case, it is not necessary to add an extra configuration such as a human sensor, so that the cost can be reduced.

  Moreover, in the entrance / exit management system of this invention, the indoor equipment control means which controls indoor equipment based on the judgment of the entrance / exit by the said judgment means can be provided (invention of Claim 2). The indoor facilities can be effectively controlled based on the reliable entry / exit determination by the determining means.

  Further, in the entrance / exit management system of the present invention, the determination means executes error processing when the next authentication operation is not performed within a predetermined time after the door opening / closing detection means detects the door opening / closing. You may comprise so that (Invention of Claim 3). By setting a certain time appropriately (necessary and sufficient time), if an authorized person makes a mistake in entering and leaving the room (how to use the authentication terminal), error handling will be performed promptly. It becomes effective.

  As a method for performing authentication in the present invention, a code such as a barcode or a two-dimensional code is used, which uses a non-contact IC card or RFID tag that stores an ID, uses a magnetic card that records an ID, or the like. Various methods such as using a card, using a personal identification number (password), and using a physical feature of an authorized person such as a fingerprint, a voiceprint, and a vein can be employed. Accordingly, various types of authentication terminals can be employed in accordance with them.

  Hereinafter, an embodiment embodying the present invention will be described with reference to the drawings. FIGS. 1 and 2 schematically show a state in which an entrance / exit management system 2 according to this embodiment is incorporated in a room 1 that requires confidentiality, such as a company office or a laboratory. In this embodiment, for example, only employees of a company are authorized persons permitted to enter the room 1, and each employee (authorized person) also uses, for example, an employee ID for authentication. I have a non-contact IC card 3.

  Here, although not shown in detail, the IC card 3 will be briefly described. This IC card 3 has predetermined items (employee's name, department, age, card expiration date, etc.) written on the surface of a plastic substrate, and a photograph of the employee's face. Has been. As is well known, the IC card 3 incorporates an antenna coil for performing electromagnetic wave communication with a card reader, which will be described later, and an IC chip for performing data communication processing and data retention. ing. The IC chip is a rectifying / smoothing circuit for obtaining an operating power supply from a power supply signal of a card reader, a CPU for controlling communication, a modulation / demodulating circuit for modulating / demodulating transmission / reception signals, a ROM for storing operation programs, and the like. A memory or the like for storing data including ID information unique to each member is configured as one chip.

  As shown in FIGS. 1 and 2, the chamber 1 in this case has one doorway 1 a, and this doorway 1 a is opened and closed by a door 4. A lock mechanism 5 for locking and unlocking the door 4 is provided at the entrance / exit 1a. In this case, the door 4 is urged in the closing direction by a door closer (not shown), and the lock mechanism 5 is configured to automatically lock (lock) with the door 4 closed. . Further, the lock mechanism 5 is configured to unlock (unlock) the door 4 in accordance with a signal from a control device described later. Further, a door opening / closing detection sensor 6 as a door opening / closing detection means for detecting opening / closing of the door 4 is provided at the entrance / exit 1a. The room 1 is provided with lighting equipment 7 and air conditioning equipment 8 as indoor equipment.

  In this embodiment, the entrance / exit management system 2 for managing the entry / exit of the authorized person (employee) into the room 1 includes an entrance side card reader 9 as an entrance side authentication terminal and an exit as an exit side authentication terminal. The side card reader 10 is provided with a control device 11 for controlling the whole.

  Among them, the entrance-side card reader 9 is provided on the wall on the outdoor side in the vicinity of the entrance / exit 1a. Although not shown in detail, the entrance-side card reader 9 includes an antenna for performing communication by electromagnetic waves with the antenna coil of the IC card 3, a transmission / reception circuit connected to the antenna, It has a well-known configuration including a connected communication control circuit. As a result, the entrance-side card reader 9 supplies power by electromagnetic waves to the IC card 3 disposed in proximity to the reading unit on the front surface of the housing, and performs data communication (reading of ID information). ing.

  The exit-side card reader 10 has the same configuration as the entrance-side card reader 9, and is provided on a wall on the indoor side in the vicinity of the entrance / exit 1a. The data (ID information) read from the IC card 3 by the entrance-side card reader 9 and the exit-side card reader 10 is input to the control device 11. Thus, as will be described in detail later, an employee as an authorized person causes the IC card 3 possessed by himself / herself to be read (held over) by the entrance side card reader 9 or the exit side card reader 10 to perform authentication. (Confirmation of authority) is performed.

  The control device 11 includes a microcomputer including a CPU, a ROM, a RAM, and the like, and controls the entire entrance / exit management system 2. At this time, ID information (card data) of all authorized persons (employees) permitted to enter the room is registered and stored in the control device 11 in advance. As described above, reading data (ID information) from the entrance-side card reader 9 and the exit-side card reader 10 is input to the control device 11, and the control device 11 is registered in advance. By comparing with the ID information of the authorized person (employee), confirmation processing (authentication) as to whether the person is authorized is performed.

  Further, as described above, the control device 11 controls the unlocking of the lock mechanism 5. Further, a door opening / closing signal from the door opening / closing detection sensor 6 is input to the control device 11. In the present embodiment, the control device 11 also has a function of automatically turning on / off the power of the lighting equipment 7 and the air conditioning equipment 8, and functions as an indoor equipment control means. The RAM of the control device 11 stores an occupancy flag indicating whether each employee (authorized person) is occupying the room 1.

  As will be described in detail later in the explanation of the operation (flowchart explanation), the control device 11 performs the authentication operation (reading of ID information) of the entrance side card reader 9 or the exit side card reader 10 by its software configuration. The door 4 of the entrance / exit 1a is unlocked by the lock mechanism 5 based on the confirmation of the authorized person. At the same time, the entry and exit of the authorized person is determined as described later. Therefore, the control device 11 functions as a lock release control unit and a determination unit.

  At this time, in making the above determination, the control device 11 confirms the authorized person by the authentication operation of the entrance-side card reader 9, and opens / closes the door 4 by the door opening / closing detection sensor 6 after unlocking the door 4. When the same authorized person is confirmed by the authentication operation of the exit-side card reader 10, it is determined that the authorized person has entered (the authorized person's occupancy flag is set). 1).

  Further, the controller 11 confirms the authorized person by the authentication operation of the exit-side card reader 10, and the door opening / closing detection sensor 6 opens / closes the door 4 (whether it has changed from closed to open) after the door 4 is unlocked. Then, when the same authorized person is confirmed by the authentication operation of the entrance side card reader 9, it is determined that the authorized person has left the room (the resident flag of the authorized person is set to 0). ing.

  Furthermore, in this embodiment, the controller 11 determines whether to enter or exit the room, and after the door opening / closing detection sensor 6 detects the opening / closing of the door, the controller 11 performs the following within a certain wait time (for example, 30 seconds). When the authentication operation of the entrance side card reader 9 or the exit side card reader 10 is not performed, error processing is executed. In this embodiment, the control device 11 automatically turns on the lighting equipment 7 and the air conditioning equipment 8 when it is judged that there is no person in the room 1 based on the judgment of the entrance / exit. It is supposed to be turned off.

  Next, the operation of the above configuration will be described with reference to FIGS. As described above, in the entrance / exit management system 2 of the present embodiment, an employee (authorized person) who wants to enter the room 1 holds the IC card 3 possessed by himself / herself as shown in FIG. 9 (arrow A), when the door 4 is unlocked, the door 4 is opened to enter the room (arrow B), and after entering the room (within 30 seconds after the door 4 is opened) This time, the IC card 3 is operated by the procedure of causing the exit side card reader 10 to read it (arrow C).

  Further, when an employee who is present in the room 1 wants to leave the room, as shown in FIG. 2, the IC card 3 possessed by the employee is read by the exit side card reader 10 (arrow D), When the door 4 is unlocked, the door 4 is opened to leave the room (arrow E), and after exiting the entrance / exit 1a (within 30 seconds after the door 4 is opened), the IC card 3 that was read earlier is removed. This time, the operation is performed in a procedure of causing the entrance-side card reader 9 to read (arrow F).

  The flowchart of FIG. 3 shows a procedure of processing executed in the entrance / exit management system 2 (mainly the control device 11) when entering the room (when the IC card 3 is read in the entrance side card reader 9 from the standby state). The flowchart of FIG. 4 is executed in the entrance / exit management system 2 (mainly the control device 11) when leaving the room (when the IC card 3 is read in the exit side card reader 10 from the standby state). The processing procedure is shown.

  That is, as shown in FIG. 3, when the IC card 3 is read in the entrance side card reader 9 from the standby state (Yes in step S1), in step S2, the entrance side card reader 9 The read data (ID information) of the IC card 3 is input to the control device 11. In step S3, the sent ID information is compared with previously registered ID information to authenticate whether the person is authorized to enter the room.

  If the authentication is OK (Yes in step S3), it is determined in next step S4 whether or not the occupancy flag in the RAM corresponding to the corresponding card data (authorized person) is 0. Here, if the authentication is NG in step S3 (No) or if the occupancy flag is not 0 in step S4 (No), in step S5, error handling, for example, buzzer Notification by ringing, lighting of the lamp, etc. is performed, and then, it returns to the standby state. In this case, since the door 4 remains locked, it goes without saying that an unauthorized person cannot enter the room.

  In contrast, if the authentication is OK and the occupant's occupancy flag is 0 (Yes in step S4), an unlock signal is sent to the lock mechanism 5 in step S6. The door 4 is unlocked. In the next step S7, it is determined from the signal of the door open / close detection sensor 6 whether the door 4 has changed from the closed state to the open state. When the door 4 is opened (Yes in step S7), a wait time (for example, 30 seconds) is set in the next step S8, and counting is started.

  In step S9, it is determined whether or not the exit-side card reader 10 has read the IC card 3. Here, when there is no reading operation of the IC card 3 in the exit side card reader 10 (No in step S9) and the wait time elapses (Yes in step S10), error processing is performed in step S11. Again, for example, a notification is given by sounding a buzzer or turning on a lamp, and the apparatus returns to a standby state.

  If there is a reading operation of the IC card 3 in the exit side card reader 10 before the wait time has elapsed (Yes in step S9), the IC card 3 read by the exit side card reader 10 in step S12. Data (ID information) is input to the control device 11. In step S13, the sent ID information is authenticated. If the authentication is NG (No in step S13), error processing is performed in step S16, and the process returns to step S9.

  Here, the reason why the authentication is NG is, for example, that an authorized person who wants to enter the room reads an incorrect card by another person immediately before trying to read the IC card 3 with respect to the exit-side card reader 10. There may be cases where the authorized person trying to enter the room tries to read the wrong card. Therefore, by returning to step S9, if the authorized person who intends to enter the room causes the correct IC card 3 to be read this time, it is possible to return to the regular entry process.

  If the authentication is OK in step S13 (Yes), whether or not the ID information sent in step S14 matches the data read by the entrance-side card reader 9 in step S1. To be judged. If the ID information matches, that is, if the IC card 3 is read by the same authorized person (Yes in step S14), the corresponding card data (authorized person) is handled in step S15. The occupancy flag in the RAM is set to 1 (occupancy), and the standby state is restored.

  If the ID information does not match in step S14 (No), the process proceeds to step S17, and the occupancy flag of the authority of the corresponding card data (ID information) (read in step S9) is 1. It is judged whether there is. Here, when the occupancy flag is 1 (Yes), the occupant who has attempted to enter the room is already in the room immediately before attempting to read the IC card 3 with respect to the exit side card reader 10. Since it is predicted that another authorized person has caused the exit-side card reader 10 to read the IC card 3 for leaving the room, the process proceeds to step S26 in the flowchart of FIG. 4 to be described later.

  If the occupancy flag is 0 (No in step S17), the process proceeds to step S16, error processing is performed, and then the process returns to step S9. Thus, if the authorized person who wants to enter the room allows the correct IC card 3 to be read, it is possible to return to the regular entry processing.

  As described above, when the authorized person enters the room 1, the IC card 3 possessed by the authorized person is read by the entrance side card reader 9, and after entering the room, the exit side card reader 10 reads the IC card 3. By following the regular procedure, the occupant's occupancy flag is set to 1 (occupancy). Therefore, if the authorized person does not enter the room after opening the door 4 after the entrance card reader 9 has read the IC card 3, it is determined that the authorized person has entered the room. It will not be done, and it is possible to determine the entrance to the room with certainty.

  On the other hand, when the authorized person in the room 1 leaves the room, that is, when the reading operation of the IC card 3 is performed in the exit-side card reader 10 from the standby state, the processing shown in the flowchart of FIG. Executed. That is, when the IC card 3 is read by the exit side card reader 10 (Yes in step S21), the data (ID information) of the IC card 3 read by the exit side card reader 10 is transferred to the control device in step S22. 11 is input. In step S23, the sent ID information is compared with previously registered ID information to authenticate whether or not the person is authorized to enter the room.

  If the authentication is OK (Yes in step S23), it is determined in next step S24 whether or not the occupancy flag in the RAM corresponding to the corresponding card data (authorized person) is 1. Here, if the authentication is NG in step S23 (No), or if the occupancy flag is not 1 in step S24 (No), error processing (buzzer sounding) is performed in step S25. Notification by lighting the lamp or the like), and then returns to the standby state.

  On the other hand, if the authentication is OK and the occupant's occupancy flag is 1 (Yes in step S24), an unlock signal is sent to the lock mechanism 5 in step S26. The door 4 is unlocked. In the next step S27, it is determined from the signal of the door opening / closing detection sensor 6 whether the door 4 has changed from the closed state to the open state. When the door 4 is opened (Yes in step S27), a wait time (for example, 30 seconds) is set in the next step S28, and counting is started.

  In step S29, it is determined whether or not the IC card 3 has been read by the entrance-side card reader 9. Here, when there is no reading operation of the IC card 3 in the entrance-side card reader 9 (No in Step S29), if the wait time has elapsed (Yes in Step S30), error processing is performed in Step S31, Return to standby.

  If there is a reading operation of the IC card 3 in the entrance side card reader 9 before the wait time elapses (Yes in step S29), the IC card 3 read by the entrance side card reader 9 in step S32. Data (ID information) is input to the control device 11. In step S33, authentication of the sent ID information is performed. If the authentication is NG (No in step S33), error processing is performed in step S36, and the process returns to step S29.

  If the authentication is OK in step S33 (Yes), whether or not the ID information sent in step S34 matches the data read by the exit side card reader 10 in step S21. To be judged. If the ID information matches, that is, if the IC card 3 is read by the same authorized person (Yes in step S34), the corresponding card data (authorized person) is handled in step S35. The occupancy flag in RAM is set to 0.

  Further, in step S38, it is determined whether all occupancy flags are 0, that is, whether there is no one in the room 1. If all occupancy flags are 0 (Yes), in step S39. After turning off the lighting equipment 7 and the air conditioning equipment 8 in the room 1, the apparatus returns to the standby state. If all the occupancy flags are not 0 (No in step S38), the process returns to the standby state.

  On the other hand, if the ID information does not match in step S24 (No), the process proceeds to step S37, and the occupant's occupancy flag of the corresponding card data (ID information) (read in step S29) is set. Whether it is zero is determined. Here, when the occupancy flag is 0 (Yes), immediately before the authorized person who tried to leave the room attempts to read the IC card 3 with respect to the entrance-side card reader 9, another authorized person Since the case where the IC card 3 is read by the entrance side card reader 9 for entering the room is predicted, the process proceeds to step S6 in the flowchart of FIG. If the occupancy flag is 1 (No in step S37), the process proceeds to step S36, error processing is performed, and then the process returns to step S29.

  As described above, when the authorized person leaves the room 1, the IC card 3 possessed by the authorized person is read by the exit side card reader 10, and after leaving the room, the entrance side card reader 9 reads. The occupant's occupancy flag is set to 0 by following the regular procedure. Accordingly, if the authorized person does not leave the room after opening the door 4 after the exit card reader 10 reads the IC card 3, it is determined that the authorized person has left the room. It is no longer done, and it is possible to reliably determine whether to leave the room. In addition, the lighting equipment 7 and the air conditioning equipment 8 can be controlled (the power is turned off when absent) based on the reliable determination of the entrance / exit.

  Thus, according to the entrance / exit management system 2 of the present embodiment, the authorized person not only enters the room by unlocking the door 4 by the authentication operation in the entrance side card reader 9, but the authorized person actually enters the room. Thus, it is determined that the user has entered the room only after the outlet card reader 10 is confirmed to be the same authorized person by the authentication operation. Further, even when leaving the room, not only the door 4 is unlocked by the authentication operation in the exit side card reader 10 but also the room is left, and the authorized person actually leaves the room and the authentication operation of the entrance side card reader 9 has the same authority. It is determined that the person has left the room only after the person is confirmed.

  As a result, it is possible to reliably determine the entry and exit of the authorized person by performing the authentication operation twice each when entering and leaving the room. At this time, since it is not necessary to add an extra configuration such as a human sensor as described in the conventional example, an inexpensive configuration can be used.

  In particular, in this embodiment, the facilities 7 and 8 in the room 1 can be effectively controlled based on the reliable entry / exit determination. Furthermore, in this embodiment, since the error processing is executed when the next authentication operation is not performed within a certain time after the opening / closing of the door 4 is detected, the authorized person can enter and leave the room ( When the card reader 9, 10) is wrong, error processing is performed promptly, which is more effective.

  In the above embodiment, the card readers 9 and 10 are used as the authentication terminals on the entrance side and the exit side, and the non-contact type IC card 3 is configured to be read by the card readers 9 and 10. In addition, as a method for performing authentication, other than using an RFID tag, using a magnetic card in which an ID is recorded, using a card on which a code such as a barcode or a two-dimensional code is written, a password (password) is used. It is possible to employ various methods such as using physical characteristics of an authorized person such as a fingerprint, a voiceprint, and a vein. Accordingly, various types of authentication terminals can be employed in accordance with them.

  Moreover, in the said Example, although the entrance / exit management system 2 controlled the illumination equipment 7 and the air conditioner 8 in the room 1, control as a power supply of various office equipment, a hot water supply equipment, etc. as an equipment. It is also possible to perform such control, and such indoor facilities may be controlled as necessary. Further, even when two or more entrances are provided in one room, the same can be implemented by providing an authentication terminal on the entrance side and exit side in each entrance / exit part. In addition, the fixed time (wait time) is not limited to 30 seconds and can be set as appropriate, and the present invention can be implemented with appropriate changes within a range not departing from the gist.
