Description

  The present invention is adopted in various buildings such as ordinary houses and apartment houses, and uses the ID key storing key data (password information) necessary for locking and unlocking the lock, and normally authenticates the key data obtained from the ID key. The present invention relates to a lock system that locks and unlocks the lock only when the lock is released.

  In recent years, card-type electric locks have been widely used in entrances and exits of commercial facilities and public facilities such as hotels and office buildings, entrances and entrances of housing complexes and ordinary houses. This card-type electric lock uses a card-like storage medium storing various data such as specific encryption and locking / unlocking information assigned in advance for each electric lock as a key card. Data (for example, locking / unlocking data with a specific encryption) is read, and the read various data are collated with information registered in advance to determine the legitimacy. Only when it is normally authenticated, locking / unlocking is performed.

  Such card-type electric locks are trusted in terms of security because they prevent unauthorized locking / unlocking actions such as picking and it is very difficult to duplicate keys. In addition, since various data for each key card is managed by the host computer, there is no worry about data corruption and the key card can be reissued even if the key card is lost. As a card lock system using such a card type electric lock, for example, an access control system disclosed in Patent Document 1 below is known.

  As shown in FIG. 3, the entrance / exit management system 101 disclosed in Patent Document 1 includes a door 102 as an entrance / exit management gate, an electric lock 103 attached to the door 102, and an individual of a person trying to pass through the door 102. Schematic configuration comprising a plurality of magnetic card readers 104 and 105 acting as a plurality of personal identification devices for identifying information, and a card controller 106 connected to the plurality of magnetic card readers 104 and 105 and controlling the electric lock 103 Is done.

The card controller 106 determines that the only electric lock drive unit K (104, 105) connected to the electric lock 103 and the personal information identified by one of the magnetic card readers 104 and 105 pass through the door 103. It is determined whether or not it is information on a permitted person. If it is information on a person who is permitted to pass, a signal for driving the electric lock 103 is generated in the electric lock driving section K (104, 105), and the door is opened. And a determination unit 107 that opens 103. A computer 108 equipped with management software is connected to the card controller 106 via a communication cable 109.

  However, in this type of conventional card lock system, even if key data (password information) is obtained from an ID key not registered in the system, only an error is notified to the user, which is effectively intimidating. In particular, it did not have a warning function.

  In a conventional card lock system having an error notification function, if an ID key is lost, there is a risk of unauthorized entry by bringing the ID key close to the reader and reading the key data. It was not possible to counter the actions of unauthorized users, such as searching for doors that can be unlocked with the.

  Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide a lock system that can effectively prompt a warning to an unauthorized user.

In order to achieve the above-described object, the lock system according to claim 1 uses an ID key storing key data necessary for locking and unlocking the lock, determines the validity of the key data of the ID key, In the lock system that locks and unlocks the lock only when the key data is normally authenticated,
At least one of a threatening action for threatening the user of the ID key and a use restricting action for stopping the use of the ID key as a countermeasure action content when setting the locking / unlocking condition before the lock and not satisfying the locking / unlocking condition A setting section for setting
An information reading unit capable of reading key data stored in the ID key and writing information to the ID key;
When reading the key data of the ID key by the information reading unit, if the content of the counter action is a threatening action without satisfying the locking / unlocking condition, a sound or display different from the key data reading error of the ID key The informing unit is controlled so as to threaten, and when the content of the counter action does not satisfy the locking / unlocking condition and the use operation is a use restriction operation, a use prohibition ID for invalidating the operation by the ID key is written in the ID key. And a control unit that controls the information reading unit.

  According to the lock system of the present invention, when the ID key is operated in the preset special operation mode, a threatening operation or a use restriction operation based on the content of the counter action is performed when the lock / unlock condition is not satisfied. It is a great threat to search for usable readers, and it is possible to prevent repeated use and intrusion of unauthorized use by unauthorized users of ID keys, and to reduce the use of illegally obtained ID keys. can do.

  Hereinafter, the best mode of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing a schematic configuration of a lock system according to the present invention, and FIG. 2 is an operation flowchart of the lock system according to the present invention.

  As shown in FIG. 1, the lock system 1 of this example is schematically configured to include a reader 10 and an ID key 20. First, the configuration of the reader 10 will be described. As shown in FIG. 1, the reader 10 includes a setting unit 11, a storage unit 12, an information reading / writing unit 13, a control unit 14, and a notification unit 15.

  The setting unit 11 includes various input keys such as numeric keys and operation buttons, and a display such as a liquid crystal display. For example, the setting unit 11 operates normally based on a user's input operation according to a predetermined procedure while viewing the display screen of the display. One of two types of modes and a special operation mode is selected, and various settings relating to lock / unlock control of the lock in the selected mode are performed.

  In this example, the normal operation mode is a mode in which the lock / unlock control of the lock can be performed by a normal lock / unlock operation in a situation where the user uses the ID key 20 such as when the user is at home. It is.

  In the special operation mode, for example, when the user does not use the ID key 20, such as when the user is absent or at bedtime, the predetermined locking / unlocking condition is satisfied even if the ID key 20 is operated. If there is no lock, the lock is not unlocked.

  More specifically, the special operation mode is a mode for preventing the ID key 20 from being illegally used. In this special operation mode, for example, a time condition that defines a time zone that is not used in the user's life situation, such as a time between the user's going out time and returning home time, or a sleeping time zone at home, such as different buildings and different levels The user inputs various settings such as a use prohibition condition for prohibiting the use of a different ID key 20 according to lifestyle, and sets various locking / unlocking conditions.

  Also, in this special operation mode, the content of the counter operation for performing a counter operation against an unauthorized user who has illegally used the ID key 20 during the special operation mode is appropriately set according to the installation environment, the operation status, and the like. The content of the counter action includes, for example, a buzzer sound or other intimidating action such as LED lighting, and a use restricting action for invalidating the action by the ID key 20. The special operation mode is released by, for example, switching to the normal operation mode with the mode selection screen displayed on the display of the setting unit 11 according to a predetermined operation procedure by the user. Can be done by.

  The storage unit 12 is composed of, for example, a magnetic or optical storage medium or a semiconductor memory such as a ROM or a RAM. The storage unit 12 includes key data for authentication for determining whether or not key data assigned to each ID key 20 is valid, locking / unlocking conditions and countermeasures in the special operation mode set by the setting unit 11. Various setting contents such as operation contents and various data relating to lock / unlock control of the lock such as a status signal (door open / close state signal and lock / unlock state signal) as monitor information are stored.

  The information reading unit 13 has a read / write function for reading and writing information with the ID key 20 by non-contact communication. In the information reading unit 13, when the ID key 20 comes close to the reader 10, the key data of the ID key 20 is read without contact, and the read key data is output to the control unit 14. Further, the information reading unit 13 does not satisfy the locking / unlocking condition in the special operation mode, and information (usage prohibition ID) for invalidating the operation by the ID key 20 when the use restriction operation is set as the content of the counter operation. ) Is written in the ID key 20 under the control of the control unit 14.

  The control unit 14 is composed of, for example, a microcomputer such as a CPU, ROM, or RAM, and compares the key data read from the ID key 20 during the locking / unlocking operation with the key data for authentication stored in the storage unit 12 as a key. The validity of the data is determined. Then, when the key data is normally authenticated in the normal operation mode, the control unit 14 controls locking / unlocking of the lock according to the current lock and door state. In addition, the control unit 14 controls the locking and unlocking of the lock according to the current lock and door state when the key data is normally authenticated in the special operation mode and the locking and unlocking conditions are satisfied. .

  Furthermore, the control unit 14 performs control according to the content of the countermeasure operation when the locking / unlocking condition is not satisfied in the special operation mode. That is, when a threatening action is set as the counter action content, a threatening execution signal for performing a threatening action is output to the notification unit 15. Further, when the use restriction operation is set as the content of the countermeasure operation, the information reading unit 13 is controlled so that information for invalidating the operation by the ID key 20 (use prohibition ID) is written in the ID key 20.

  Further, when the information reading unit 13 reads the use prohibition ID from the ID key 20 together with the key data, the control unit 14 prohibits the lock / unlock operation of the lock using the ID key 20 regardless of the operation mode, and performs a threatening operation. Is output to the notification unit 15. Thereby, the sounding means 15a and the display means 15b of the alerting | reporting part 15 are drive-controlled, and intimidation operation | movement is performed.

  The notification unit 15 includes a sounding means 15a for generating an error sound when reading the key data of the ID key 20 and a warning sound for threatening in the special operation mode, and a display means 15b that can be lit / flashed, such as an LED. It is prepared for. The notification unit 15 sets driving conditions for the sounding means 15a and the display means 15b in advance from the setting unit 11, and when a threatening execution signal is input from the control unit 14, the sounding means 15a and the display are displayed based on the driving conditions. Drive control of the means 15b is performed.

  Next, the configuration of the ID key 20 will be described. The ID key 20 is composed of, for example, a remote control key, a non-contact card, or the like, and has a read / write function for transmitting and receiving various types of information without contact with the reader 10 described above. The ID key 20 includes a storage unit 21 made of, for example, a semiconductor memory such as an IC chip, ROM, or RAM.

  In order to authenticate whether the ID key 20 is valid or not in the storage unit 21, key data including device information such as a room number and device number, and unlocking / locking information such as password information necessary for locking / unlocking the lock. Is remembered. The key data of the ID key 20 is sent to the reader 10 by performing non-contact communication close to the reader 10.

  Next, the operation of the reader 10 during operation of the lock system 1 having the above configuration will be described with reference to FIG. In the lock system 1 of this example, the normal operation mode is set during the initial operation. When operating in the special operation mode, the mode is switched from the setting unit 11 to the special operation mode, and the locking / unlocking condition and the content of the opposing operation are set.

  As shown in FIG. 2, when the ID key 20 is brought close to the reader 10 and reading of key data of the ID key 20 is started in the actual operation (ST1), it is determined whether or not the special operation mode is set (ST2). When it is determined that the operation mode is the normal operation mode (ST2-No), the operation mode is shifted to the normal operation mode, and it is determined whether the reading of the key data from the ID key 20 is completed (ST3). If it is determined that reading of the key data from the ID key 20 has been completed (ST3-Yes), it is determined whether or not the key data has been successfully authenticated (ST4). If it is determined that the key data has been successfully authenticated (ST4-Yes), an unlock signal or a lock signal is output to an electric lock (not shown) to unlock the lock according to the current lock and door state. (ST5).

  If the reading of the key data from the ID key 20 is not completed and it is determined that there is a reading error (ST3-No), an error will occur due to the buzzer sounding or LED lighting by the notification unit 15 in order to re-read the key data. (ST6). Further, even when the key data is not normally authenticated and is authenticated as abnormal, the fact of an error is notified by the buzzer sounding by the notification unit 25 or the lighting of the LED (ST6).

  If it is determined that the operation mode is the special operation mode in ST2 (ST2-Yes), it is determined whether or not the locking / unlocking condition is satisfied (ST7). When it is determined that the locking / unlocking conditions are satisfied (ST7-Yes), the operation proceeds to ST3, and the same operation as in the normal operation mode is executed. On the other hand, if it is determined that the locking / unlocking condition is not satisfied (ST7-No), the content of the counter action is determined (ST8). That is, it is determined whether the content of the counter action is “intimidation action” or “use restriction action”.

  If the content of the counter action is determined to be “intimidating action” (ST8—intimidating), the intimidating action is started by the buzzer sounding or LED lighting by the notification unit 15 distinguished from the time of error (ST9). Specifically, in the case of a buzzer, a short and high sound such as “beep” sounds when an error occurs, and a large and long sound such as “beep” sounds when threatened. In the case of an LED, it is lit briefly when an error occurs and flashes for a long time when threatened. Then, when the threatening time determined by the setting of the countermeasure content of the prohibition operation has elapsed, the operation returns to the initial operation.

  If the content of the counter action is determined to be “use restriction operation” (ST8—use restriction), a use prohibition ID for invalidating the operation by the ID key 20 is written to the ID key 20 (ST10). Thus, when the ID key 20 in which the use prohibition ID is written is in contact with another reader 10 and performs non-contact communication, the reader 10 invalidates the operation by the ID key 20 and the sounding means of the notification unit 15 The threatening action by 15a and the display means 15b is executed, and lock / unlock control before the lock is prohibited.

  In the operation example shown in FIG. 2, the threatening action and the use restricting operation are discriminated in ST8, and the process is performed according to the set counter action, but the use restricting action and the threatening action are set simultaneously. It is also possible. In this example, the reader 10 is described as including the setting unit 11. However, for example, a setting device configured separately from the reader 10 may have the function of the setting unit 11.

  As described above, in the lock system 1 described above, the user sets in advance either the normal operation mode or the special operation mode, and when the reading of the key data from the ID key 20 is started, Which mode is the current mode is determined. If the result of the mode discrimination is the normal operation mode, whether or not the read key data is valid is authenticated, and locking / unlocking control is performed based on the authentication result. On the other hand, in the special operation mode, it is determined whether or not the locking / unlocking conditions set in advance by the user are satisfied. When the locking / unlocking conditions are satisfied, the same locking / unlocking control as in the normal operation mode is performed. If the locking / unlocking condition is not satisfied, the threatening operation or the use restriction operation is selectively executed according to the content of the countermeasure operation, or the use restriction is applied so that the operation by the ID key 20 is invalidated.

  Thereby, it becomes a big threat to the search for a reader that can be used by a suspicious person, and an intruder of an unauthorized user who repeats an illegal action using an ID key can be prevented in advance. Further, mischief with an illegally obtained ID key can be reduced. Furthermore, since the user can set the locking / unlocking conditions and the content of the counter action when the locking / unlocking conditions are not satisfied, the contents of the counter action can be properly used according to the purpose, from threatening to use stoppage.

  Since the lock system itself has both a threatening function for unauthorized users of ID keys and a function for restricting the use of ID keys, devices for threatening unauthorized users such as sensor lights and dummy cameras are used. It is possible to provide a lock system that can effectively threaten unauthorized users and has excellent crime prevention.
