Description

  The present invention relates to an electric lock system that uses a portable terminal such as a cellular phone as a key and can confirm various information when collating with the portable terminal, thereby improving convenience.

  2. Description of the Related Art In recent years, electric lock systems using card-type electric locks have become widespread at entrances and exits of commercial facilities and public facilities such as hotels and office buildings, entrances and entrances of apartment houses and ordinary houses. This electric lock system uses a card-like storage medium in which various kinds of card information such as specific codes and lock / unlock information assigned in advance for each electric lock in each place are stored as a lock / unlock card, and is stored in this lock / lock card. Only when the various data (for example, locking / unlocking data by specific encryption) is read, the read card information is collated with the pre-registered information to determine the correctness, and the authentication is successful, the state of the lock at that time The lock is electrically locked / unlocked in accordance with (open / closed state of door, locked / unlocked state of lock).

  In addition, such an electric lock system is trusted in terms of security because it prevents an illegal locking / unlocking action such as picking and it is very difficult to duplicate a key. Furthermore, since various data for each locking / unlocking card is managed by the host computer, there is no fear of data corruption and the locking / unlocking card can be reissued even if the locking / unlocking card is lost. And as an electric lock system using such a card type electric lock, what is indicated by the following patent documents 1 is publicly known, for example.

  3A and 3B are schematic perspective views of an electric lock system disclosed in Patent Document 1 below. As shown in FIGS. 3A and 3B, for example, a lock device 101 is provided for each door of each room such as a hotel. The locking device 101 is disposed at a predetermined position of the door 200 by a fixing means such as a screw, and when the door 200 is closed, the unlocking solenoid is energized to automatically advance and retract the final fastening bolt 102. . The lock device 101 is provided with a manual card reader 105, an indicator lamp 106 for displaying unlocking, a keyhole 107 and a thumb turn 108.

  By the way, in the conventional electric lock system, when the lock / unlock card is collated, it is impossible to display the result so that it can be seen on the card. For this reason, the collation result is notified to the user by LED lighting (normal: green, abnormal: red, etc.) and buzzer sound. However, in this method, there are cases where it is difficult to see the lighting state of the LED due to external light, and there are situations where it is difficult to hear the buzzer sound due to ambient noise, and there are situations where it is difficult for the user to understand the verification result.

  In addition, when the lock / unlock operation of the lock / unlock card issued to the user for some reason at the time of the lock / unlock operation results in a NG determination and a verification error occurs, the setting information and operation history including the error information are stored in the card type. Although it is designed to be held by an electric lock, a dedicated device is required to confirm this information. For example, in the case of a user unfamiliar with card operation, if an NG determination is made by the locking / unlocking operation in the guest room, the cause of the NG determination and the coping method will not be known, and the door cannot be unlocked and unlocked. Claim. The employee of the front desk who received the complaint carries a data input device having a log collection function and accompanies a guest room that is judged NG, and uses the data input device to store the information held in the card-type electric lock. After the collection, the cause of the NG judgment could only be specified by returning to the front again and confirming the information collected from the card type electric lock. For this reason, the burden on the employees is large, and it takes time to deal with them, so the users are not satisfied. As a result, the hotel has lost a lot of money.

  Accordingly, the present invention has been made in view of the above problems, and provides an electric lock system that can use a mobile terminal as a key, perform various information checks when collating with the mobile terminal, and improve convenience. It is intended to do.
