In this example, since the card with a non-contact IC chip is adopted as the guest card 30, the information reading section 21 is configured by a non-contact type card reader / writer.

  The information reading unit 21 performs polling on the guest card 30 that is close within a predetermined range at a fixed period, and reads the locking / unlocking information necessary for the locking / unlocking operation when the guest card 30 approaches within the predetermined range. I do. The information reading unit 21 reads the room usage information and the usage time count value written in the guest card 30 at the first unlocking operation after the check-in procedure, and outputs them to the electric lock control unit 22. Further, the information reading unit 21 writes an abnormality flag ON signal to the guest card 30 for turning on the time abnormality flag stored in the guest card 30 when the internal clock in the card type electric lock 20 is out of time. doing.

  The electric lock control unit 22 performs drive control of each unit constituting the card type electric lock 20. The electric lock control unit 22 compares the locking / unlocking information read from the guest card 30 during the locking / unlocking operation with the authentication locking / unlocking information stored in the storage unit 23 to determine the correctness of the locking / unlocking information. When authenticated, a drive control signal is output to the locking / unlocking mechanism 25 according to the current lock and door state. The electric lock control unit 22 controls the counting process (counting up or counting down) in the clock unit 24 using the usage time count value from the guest card 30.

  Further, the electric lock control unit 22 compares the room use information from the guest card 30 with the current time measured by the clock unit 24 at the time of the first unlocking operation after the check-in procedure, and the storage unit 23. And a time shift determining means 23a for determining whether or not the time shift determination information described later is within an allowable range, and when the time measured by the clock unit 24 exceeds the time range of the time shift determination information. If determined, the abnormality flag ON signal for turning on the time abnormality flag is controlled to be written in the guest card 30 via the information reading unit 21.

  The storage unit 23 is configured by, for example, a magnetic or optical storage medium or a semiconductor memory such as a ROM or a RAM. The storage unit 23 is device information of each device constituting the card-type electric lock 20, various card information of the guest card 30 read by the information reading unit 21, and legitimate information that the read / unlock information is unlocked / unlocked. Authentication locking / unlocking information for determining whether or not, time deviation determination information in which an allowable time range for determining whether or not a time lag has occurred in the time measured by the clock unit 24, and monitor information Various data relating to locking / unlocking control, such as state signals (door open / closed state signal, locking / unlocking state signal of lock, locking / unlocking operation history) are stored.

  The clock unit 24 is composed of an RTC (RealTimeClock: clock circuit) and clocks the current date and time. Further, the clock unit 24 starts a count process (counting up or counting down) of the usage time count value from the guest card 30 under the control of the electric lock control unit 22.

[Processing operation]
Next, the processing operation in the card lock system 1 described above will be described. Here, an example of a processing operation between a guest using a hotel and checking in will be described.

  The guest goes to the front desk to perform the check-in procedure, and receives the guest card 30 used at the time of locking and unlocking the room where the guest stays. The guest card 30 stores various types of card information such as locked / unlocked information of the reserved room, room use information indicating a stay period, and a use time count value set based on the room use information. Then, the guest brings the guest card 30 close to a predetermined range of the card type electric lock 20 installed in the room where the guest card 30 is staying, and reads various stored card information.

  The card-type electric lock 20 compares the locking / unlocking information read from the guest card 30 with the authentication locking / unlocking information stored in the storage unit 23 to determine the validity of the locking / unlocking information. The lock is locked and unlocked according to the current lock and door status. At the same time, the room use information from the guest card 30 and the current time measured by the clock unit 24 are collated to determine whether the time measured by the clock unit 24 is within the allowable range of the time deviation determination information. And the control based on the count processing of the usage time count value is started.

  When the timekeeping time of the clock unit 24 exceeds the range of the time deviation determination information (that is, when an error is confirmed in the timekeeping time in the card type electric lock 20), the abnormal flag ON signal is sent to the information reading unit. The guest card 30 is controlled to be written via 21, and the time abnormality flag of the guest card 30 is turned ON. As a result, since the counting process based on the usage time count value from the guest card 30 is performed, even if the clock time of the clock unit 24 is incorrect, it is within the range of the usage time count value (that is, within the usable period). ), The user can freely lock and unlock the room.

  In addition, after the guest's check-out procedure is completed, the returned guest card 30 is read to check whether the time abnormality flag is turned on. If the flag is turned on, go to the corresponding room. Reset the time using a dedicated data setter.

  As described above, the card lock system described above is set based on at least the locking / unlocking information necessary for the locking / unlocking operation, the room usage information including the date / time information of the room usage time, and the usage time of the room used by the user. The guest card 30 in which the usage time count value is stored in advance is handed over to the user, and the guest card 30 is visited to the room to be used. The card-type electric lock 20 reads the locking / unlocking information from the guest card 30 at the first unlocking operation after check-in, and determines its validity. At the same time, the card-type electric lock 20 collates the room use information with the current time measured by the clock unit 24, and the time deviation of the time measured by the clock unit 24 is within the range of the time deviation determination information. It is determined whether or not there is a time error flag of the guest card 30 when a predetermined deviation occurs in the time measured by the clock unit 24. Furthermore, the card-type electric lock 20 starts the counting process from the time when the usage time count value is read. Then, the card issuance controller 10 checks whether or not the time abnormality flag of the guest card returned after the user's checkout is turned on.

  As a result, even if the time that the card-type electric lock 20 counts is inaccurate, the locking / unlocking operation can be performed within the usable period, so that the trouble that the locking / unlocking cannot be performed due to the inaccuracy of the time. The effect which prevents can be show | played. In addition, when the clock time measured by the clock unit 24 is out of order, the user checks the guest card 30 returned from the user after the check-out procedure is completed in order to set the time abnormality flag of the guest card 30 to ON. By simply doing, it is possible to easily confirm in which room the card-type electric lock 20 has a time lag.

  By the way, in the above-mentioned form, regardless of whether the time abnormality flag is ON from the guest card 30, the guest room is controlled by the count control based on the usage time count value according to the usage time at the first unlocking operation after the check-in procedure. Although the processing content for limiting the usage time has been described, the present invention is not limited to this.

  As another control example in the above-described form, for example, the electric lock control unit 22 compares the room use information acquired at the time of the first unlocking operation after the check-in procedure with the time measured by the clock unit 24 to check the clock unit 24. The configuration may be such that the count processing is performed using the usage time count value only when a time shift exceeding the range of the time shift determination information is confirmed at the time measurement time. In this case, if the time deviation of the time of the clock unit 24 is within the range of the time deviation determination information, the guest is within the accommodation date and time range of the room use information according to the time counted by the card type electric lock 20 as a normal management form. The card 30 is controlled to be usable.

  In the present system, it is also possible to use both the management of the usable period based on the normal check-in / check-out time within the stay period and the count control based on the usage time count value. By using the management mode of the usable period in this way, the usable period of the room can be accurately managed even when the timekeeping time is distorted for some reason after check-in.
