FIG. 1 is an explanatory diagram showing an overview of the control system 1, and FIG. 2 is a block configuration diagram of the control system 1.
The control system 1 includes cabinets 2a to 2d having electric locks 3a to 3d, a computer 5 as a control device that controls locking and unlocking of the electric locks 3a to 3d through wireless communication, and operations related to locking and unlocking by the computer 5. It consists of an authentication device 4 for determining adequacy and an ID card 6 that has a unique ID and that can be read by the authentication device 4.

  Each of the cabinets 2a to 2d is a box that has an opening on the front surface and can store documents and the like inside, and the front opening can be opened and closed by a front door. Further, electric locks 3a to 3d for locking / unlocking the front door in the closed state are attached to the cabinets 2a to 2d. Each of the electric locks 3a to 3d is provided with a lock mechanism for locking and unlocking the front door, and is provided with a timer and a lock mechanism control means. After the lock mechanism is unlocked, the front door is not less than a predetermined time. When it is detected that it is in the closed state, the lock mechanism is automatically locked.

Further, each of the cabinets 2a to 2d is provided with indicator lamps (permission notification means) 8a to 8d that are turned on under the control of the computer 5 described later, and the lock mechanism control means is released to the lock mechanism control means by a pressing operation. Unlocking switches (cabinet specifying means) 7a to 7d for instructing the locking operation are provided. The unlocking switches 7a to 7d are set so that the pressing operation is valid only while the indicator lights 8a to 8d are lit.
In addition, the electric locks 3a to 3d are provided with wireless communication means for wirelessly communicating with the computer 5, receiving the unlock signal from the computer 5, and a completion signal to the computer 5 after the unlocking operation. Can be transmitted, and a locking signal can be transmitted to the computer 5 after the locking operation.

The authentication device 4 is a device for reading the unique ID of the ID card 6 and includes a reading unit capable of RFID communication. By bringing the ID card 6 close to the reading unit, for example, The unique ID can be read. Further, the authentication device 4 is connected to a computer 5 to be described later in a wired manner, and outputs the unique ID to the computer 5 when the unique ID of the ID card 6 is read.
The ID card 6 is a card body made of a synthetic resin in which an ID tag having a unique ID stored therein is stored, and possesses a unique ID that is different for each user.

  The computer 5 includes a control unit 11 such as a CPU for controlling various operations, a storage unit 12 such as a ROM for storing a registered unique ID, a display unit 13 such as a monitor, and an input unit 14 such as a keyboard. , A transmission / reception means 15 for performing wireless communication with the wireless communication means of the electric locks 3a to 3d, an interface 16 for connecting the authentication device 4, a timer 17 for measuring time, and the like.

Hereinafter, control of locking and unlocking of the cabinets 2a to 2d by the control system 1 will be described with reference to FIGS. FIG. 3 is a flowchart showing control related to locking / unlocking by the control means 11, and FIG. 4 is a flowchart showing control related to locking / unlocking on the cabinets 2a to 2d side.
In order to control locking / unlocking in the control system 1, registration of the ID card 6 to be used is necessary. Therefore, registration of the ID card 6 will be described first. The user puts the ID card 6 that he wants to use on the authentication device 4 to read the unique ID. Next, by operating the computer 5, the read unique ID is set as a usable registration ID, and a personal identification number (for example, a four-digit number) as a personal identification key corresponding to the registration ID is read. An identification number of a cabinet (in this embodiment, the cabinets 2a, 2b, and 2d are permitted) that are permitted to be unlocked by the ID card 6 having a unique ID is set, and a registration ID, The code number and the identification number are stored in association with each other. The registration of the ID card 6 is completed by this operation.

Next, locking and unlocking of the cabinets 2a to 2d using the registered ID card 6 will be described.
The authentication device 4 always transmits a calling wave from the reading unit, and immediately reads the unique ID of the ID card 6 when the ID card 6 is brought close to the reading unit such as being deceived (S1). The ID is output to the computer 5. In the computer 5, when the unique ID is input from the authentication device 4, it is determined whether or not the unique ID matches any of the registered IDs stored in the storage unit 12 (S2). Here, if the unique ID does not match any of the registered IDs (NO in S2), the locking / unlocking control is not continued because the ID card 6 is not usable (that is, the process does not proceed to S3 and subsequent steps).

  On the other hand, if the input unique ID matches any of the registered IDs (determined as YES in S2), the display unit 13 prompts the input unit 14 to input the code number. Is determined to match the password set as corresponding to the registered ID (S3). Here, if the input code number does not match the code number corresponding to the registered ID (NO in S3), the lock / unlock control is not continued because the user is not the user who should have the ID card 6 (ie, S4). I can't go on.) It should be noted that in S3, an input error of a password may be considered, so S3 may be repeatedly executed only a predetermined number of times.

  On the other hand, if the entered code number matches the code number corresponding to the registration ID (YES in S3), the cabinets 2a, 2b, 2d corresponding to the registration ID are permitted to be unlocked by the ID card 6. The unlocking signal is transmitted only to the cabinet) (S4), and unlocking is permitted. Note that no unlock signal is transmitted to the cabinet 2c.

  Here, in each cabinet 2a-2d, the radio | wireless communication means of the electric locks 3a-3d always monitors reception of an unlocking signal (S11). When the cabinets 2a, 2b, and 2d receive the unlock signal transmitted from the computer 5 as described above, the display lights 8a, 8b, and 8d are turned on (S12), and the unlock switches 7a, 7b, It is set so that the pressing operation of 7d becomes effective. When the unlocking switches 7a and 7b are operated within a predetermined time (for example, one minute) after the indicator lights 8a, 8b and 8d are turned on (YES in S13), the indicator lights 8a and 8b are turned off. Then, the lock mechanism of the electric locks 3a and 3b is unlocked so that the front door can be opened, and a completion signal is transmitted to the computer 5 (S16). On the other hand, if the unlocking switch 8d has not been operated for a predetermined time after the lighting of the indicator lamp 8d (YES in S14), the indicator lamp 8d is turned off (S15) and a lock signal is transmitted to the computer 5 At the same time, the process returns to the unlock signal standby state (ie, S11). The computer 5 determines that the cabinet is in an unlocked state upon receipt of the completion signal, and displays that fact on the display means 13.

  Further, in the cabinets 2a and 2b, after the unlocking operation, the lock condition (that is, detection of the closed state of the front door for a predetermined time or more) is satisfied (determined as YES in S17), and it is determined that the work is finished. Then, the locking mechanism is operated to lock the front door, and a locking signal is transmitted to the computer 5 (S18).

Further, when the computer 5 transmits the unlocking signal, it waits for the reception of the locking signal from the cabinets 2a, 2b, 2d (S5 and S6). Here, a predetermined time (for example, 20 minutes) is set in advance as the allowable opening time of each cabinet 2a to 2d, and in S6, it is determined whether or not the standby time has exceeded the allowable opening time. (In other words, forgetting to close it). And when a locking signal is received within the predetermined allowable opening time, it is processed as locking, such as displaying it on the display means 13 (S8). On the other hand, when the locking signal is not received beyond the allowable opening time In this case, an abnormality notification (S7), such as displaying “Cabinet 2a, forgetting to close!” Is displayed on the display means 13 to prompt the cabinet to be locked.
As described above, the locking and unlocking control of the cabinets 2a to 2d is performed.

According to the control system 1 as described above, since the cabinet can be selected and unlocked, the cabinet that is not required for every authentication of the ID card 6 is not unlocked, and the power consumption is reduced. It is possible to suppress the occurrence of forgetting to close or the like.
In addition, when the ID card 6 is authenticated, the indicator light of the cabinet that can be unlocked is lit, so that it is possible to reliably notify the user which cabinet is unlockable, which is easy to use. .

Furthermore, in order to unlock the cabinets 2a to 2d, it is necessary not only to authenticate the ID card 6, but also to input a personal identification number after the authentication of the ID card 6, so that other than the user of the ID card 6 Unlocking using the ID card 6 can be prevented. Therefore, misuse of the lost ID card 6 or the stolen ID card 6 can be prevented, and the crime prevention property is extremely high.
In addition, if the lock is not confirmed for a predetermined time after unlocking the cabinet, the state is notified by the display means 13 or the like, so that it is possible to prevent a situation in which the cabinet is left for a long time without forgetting to close it. The crime prevention property can be further improved.

  In addition, the structure which concerns on the control system of this invention is not limited to the aspect as described in the said embodiment at all, The structure which concerns on a cabinet, an electric lock, a control apparatus, an authentication apparatus, and an ID card | curd is the structure of this invention.
