  However, even the entrance / exit management system that realizes various excellent security functions as described above has the following problems. In other words, the reception room is operated in the primary release mode (meaning that it is automatically locked after a predetermined time after being unlocked with the key), and instead of handing the key to all persons using the room, Give one key per room. Therefore, if you leave the room and return without holding the key, you must have someone in your room open it each time. On the other hand, when someone leaves the room with a key, there is a problem that other people cannot enter or leave the room without knowing when the person leaving the room will return.

  In order to solve this problem, preparing keys for the number of people in the room is not a good idea considering the cost of the keys and the risk of loss. The present invention is to easily realize a key management system with sufficiently reduced risk even in the operation of such a temporary use purpose room.

The invention of the present application includes a key box including an IC card reader provided in the room for reading authentication information registered in an IC card possessed by a person who is permitted to enter a room in a building, and the read authentication. In a key management system comprising a management device that unlocks the electric lock of the room when the information is matched with the verification authentication information related to the room,
In the key management system, the electric lock is unlocked when the IC card is mounted in the key box.

  Furthermore, the present invention is a key management system that locks the electric lock when the IC card is separated from the key box.

  According to the present invention, the troublesomeness at the time of entering and leaving the room is eliminated, and the key management is ensured and simple for the visitor and the person in charge of the reception, and the key operation cost can be reduced.

The block diagram which shows the structure of the key management system concerning one Embodiment of this invention. Correlation operation flow of each function in the key management system according to the embodiment of the present invention The time sequence of the unlocking logic concerning implementation of this invention.

Hereinafter, the present invention will be described based on embodiments. FIG. 1 is a block diagram showing the configuration of a key management system showing an embodiment of the present invention. In the figure, reference numerals 12-1 to 12-3 denote card readers installed outside the doors 11-1 to 11-3 of a room to be managed such as a reception room, and 13-1 to 13-3 denote doors. Electric locks installed in 11-1 to 11-3, 14 is a management device,
15 is a network connecting the management device 14 to the card readers 12-1 to 12-3, the electric locks 13-1 to 13-3, and the key boxes 20-1 to 20-3 provided in the room, and 16 is a facility. This is an IC card possessed by a user who goes in and out.
In this example, the management apparatus 14 is configured by a plurality of rooms and supervises them. However, this is not necessarily a hierarchical configuration, but a stand-alone type that plays the role of a management apparatus in units of one room. It is also possible to deploy a controller for each room.

Each of the key boxes 20-1 to 20-3 incorporates an IC card reader (not shown). When the IC card 16 used for entering the room is attached to the key boxes 20-1 to 20-3, the key box 20-1 to 20-3 is attached to the management device 14. An unlock request signal is sent. When the IC card 16 is placed in the key boxes 20-1 to 20-3, it is always unlocked. On the other hand, when leaving the room, the IC card 16 is removed from the key boxes 20-1 to 20-3 in order to return it to the reception, etc., so that the key boxes 20-1 to 20-3 send a lock request signal to the management device 14 at that time. send. The key boxes 20-1 to 20-3 are provided at appropriate locations in each room.

Next, the operation of the present invention will be described based on the correlation flow of FIG. (For the sake of explanation, each code uses the first one)
For example, when the user goes through the door 11-1 and tries to enter the room, the user holds the IC card 16 that is lent and held over the card reader 12-1. A unique identification ID is recorded in advance on the IC card 16. The card reader 12-1 reads the identification ID from the IC card 16 (step S01 in FIG. 2). Then, the card reader 12-1 transmits a verification request including the reader address of the own device and the identification ID read from the IC card 16 to the management device 14 (step S02).

  Upon receiving the verification request, the management device 14 determines whether or not the user specified by the identification ID can pass through the door specified by the reader address, based on previously registered access permission information (step S03). And when it determines with the management apparatus 14 being able to pass, an unlocking command signal is sent with respect to the electric lock 13-1 of the door corresponding to a reader address (step S04). When receiving the unlock command signal, the electric lock 13-1 of the door 11-1 unlocks (step S05). In this way, the user can enter through the door 11-1. Further, when the management device 14 determines that the passage is impossible in step S03, the unlocking instruction signal is not output, and thus the passage of the user is rejected.

Next, when the user who enters the room attaches the IC card 16 possessed to the indoor key box 20-1, the IC card reader built in the key box reads the identification ID from the IC card 16 (step S10). Then, the key box 20-1 transmits a verification request including the reader address of the own device and the identification ID read from the IC card 16 to the management device 14 (step S12). This is confirmed by the IC card attachment / detachment confirmation (step S11) in the key box 20-1.

When receiving the collation request this time, the management device 14 determines whether or not the user specified by the identification ID can open the room specified by the reader address based on the opening permission information registered in advance (step S13). ). If the management device 14 determines that the door can be opened, it sends an unlock command signal to the electric lock 13-1 of the door corresponding to the reader address (step S14).
When receiving the unlock command signal, the electric lock 13-1 of the door 11-1 unlocks (step S05). In this way, the user can open the door 11-1 while unlocked. On the other hand, if it is determined in step S13 that the opening is not possible, the management device 14 outputs a locking command signal to the electric lock 13-1 (step S15).

The IC card attachment / detachment confirmation step shown in step S11 of the key box 20-1 is always executed at a constant cycle. When the IC card 16 is separated (removed) from the key box 20-1, the key box 20-1 transmits an IC card separation signal to the management device 14 (step S12). When receiving the separation signal this time, the management device 14 determines that the opening is impossible in the opening determination (step S13) and outputs a locking command signal (step S15). In this case, entry of users from outside is refused.

As a result, after all the IC cards are removed and the room is used, all of them leave the room and are locked (step S16). It should be noted that the timing of this locking is arbitrarily designed, such as whether a time delay is provided or a human sensor is used. Of course, as long as the door can be opened and closed freely from the inside of the room, there is no particular need for timing.

  The IC card 16 can communicate with the card reader 12 and the key box 20-1 in a non-contact manner using, for example, RFID (Radio Frequency Identification) technology. If a power-less IC card that receives radio waves from them and converts the radio waves into electric power is used, power supply to the IC card 16 becomes unnecessary. In addition, the management device 4 includes a transmission / reception unit that realizes a communication function via an intra-Internet communication network (whether wired or wireless), a storage unit that stores information, and a control unit that controls an electric lock. It is a computer system. The control unit includes a collating unit that determines whether or not a user can pass or not, and an electric lock control unit that controls the electric lock based on the determination result.

Next, in order to understand the invention of the present application, an example of a time sequence related to the operation related to the determination of whether or not to open (step S13 in FIG. 2) will be described. In the upper part of FIG. 3, the unlocking signal from the key box 20-1 to the management device 14 is shown, and the lower part shows the status transition of the electric lock. The unlock signal output by the management device starts with Off (a state where unlocking is not performed), which indicates an unused state of the room or a use end state, and starts from the locked state.
Here, at the timing indicated by the broken line on the left side, the management device 14 issues an unlock command On (unlocking state) to the electric lock 13-1 in response to the notification from the key box 20-1 that the IC card has been inserted (step) S14). As a result, the electric lock 13-1 is unlocked (step S05). Subsequently, at the timing indicated by the broken line on the right side, the management device 14 issues an unlock command Off to the electric lock 13-1 in response to notification from the key box 20-1 regarding the IC card separation (step S15). As a result, the electric lock 13-1 is in a locked state (step S16).

Industrial application fields

As described above, according to the present invention, even if it is a simple mechanism or from a security aspect such as theft prevention, if there is a key in the room, it can be regarded as being in the room. ) Is in an unlocked state, which is convenient for entering and leaving the room. In addition, when leaving the room, it is a mechanism that requires an exit operation using an IC card, and handling of entering and leaving the room is simple.
