Description

  The present invention relates to an electric lock system that electrically drives and controls a locking / unlocking device provided in various doors, and has a control function having a function of authenticating locking / unlocking information from the outside and controlling the locking / unlocking device. The present invention relates to an electric lock system using an electric lock.

  Conventionally, for example, a door of a commercial building, a public facility, or a general house has been provided with an electric lock system having a high crime prevention property in order to avoid intrusion of a suspicious person. This type of electric lock system locks and unlocks a lock by driving a driving means such as a motor and a solenoid, for example, to electrically advance and retract a dead bolt in accordance with a specific locking and unlocking signal.

FIG. 11 shows a schematic configuration of this type of general electric lock system. The electric lock system shown in FIG. 11 has an electric lock 102 installed on a door 101, an electric lock control unit 103, an electric lock 102 installed on a wall and determined to be locked or unlocked by electric means. And a locking / unlocking determining means 104 for outputting a control signal for controlling the door 101, and one side of the door 101 is connected to the door frame 106 by a hinge 105 (attached to the door frame 106 so as to be opened and closed). The locking / unlocking determination means 104 is supplied with AC power (AC100V or AC200V) by a two-wire electric wire 107, and via the electric lock control unit 103 by remote operation from an operation indicator 108 installed in the house. The lock / unlock signal is transmitted. The electric lock system as described above is known as disclosed in, for example, Patent Document 1.
Japanese Patent Laid-Open No. 10-025935

  By the way, this type of electric lock system has a configuration in which an electric lock provided on a door and an electric lock control panel for controlling locking / unlocking of the electric lock are wired via a metal fitting of the door. For this reason, when an electric lock system is introduced, not only the electric lock is installed on the door, but also an electric lock control panel for controlling the electric lock must be separately installed on a different place from the door, for example, on the wall surface of the room. Don't be. Therefore, it is necessary to secure a dedicated installation space for the electric lock control panel. In actual operation, the electric lock control panel often remains the role of a power supply or terminal block, and the installation space and cost of the electric lock control panel are often wasted. Since the wiring space and the installation space for the electric lock control panel are limited, the versatility was poor. Furthermore, when the electric lock is remotely operated, an operation indicator is connected to the electric lock control panel, so that the structure is further complicated when the electric lock system is constructed.

  In addition, the electric lock used in the conventional electric lock system has a contact signal terminal for electrically monitoring the lock / unlock state of the lock and the open / close state of the door, and a motor / solenoid drive terminal of the lock / unlock mechanism. Since it is a structure that is directly pulled out from the lock body and wired to the electric lock control panel, the wires that are wired between the electric lock and the electric lock control panel are cut by fraud, etc. There is also a risk that the electric lock may be illegally locked / unlocked by inputting a predetermined signal (signal for driving the lock / unlock drive) from the outside.

  Furthermore, when constructing an electric lock system having an authentication function, it is usually necessary to connect an ID reader to the electric lock control panel. As a result, the system has become very expensive and hinders its spread.

  By the way, in recent years, in the housing entrance market, there is a demand for electric locks that have high security and can be flexibly adapted to various operations with one door and two locks (multiple locks). The electric lock system capable of two-lock operation employs an electric thumb turn that is driven and unlocked by attaching a drive unit from the door surface of a door to which a general lock is attached. However, in the configuration employing this electric thumb turn, the drive unit is exposed on the door surface, which impairs the design of the door.

  On the other hand, electric locks that are engraved and have excellent design properties are also known, but there is no electric lock control panel compatible with multiple locks, and it is impossible to operate, price, and wire even if the current product is used in combination. there were. Moreover, since only battery operation is required, wired connection is not possible, battery replacement is required, unlocking means are limited to the remote control only, non-touch type, etc., and unlocking from the interphone, etc. Since the device cannot be linked, it could not handle various operations. Furthermore, the engraving type electric lock is not preferable in terms of crime prevention because the drive wiring for the power source is directly pulled out from the lock case.

  In addition, since the conventional electric lock has a different energization method for each lock type, the control method of the electric lock becomes complicated, and it is difficult to separate the responsibility between the electric lock side and the control side in the event of a malfunction.

  Therefore, the present invention has been made in view of the above problems, and provides an electric lock system that simplifies the configuration, reduces installation space, has excellent versatility, and can improve crime prevention. It is intended.

Information indicating the locked / unlocked state is returned to the external terminal.

  As described above, according to the present invention, since the control means for comprehensively controlling the electric lock system is incorporated in the lock body, an electric lock control panel requiring a conventional arrangement space is not required. In addition to saving the space of the electric lock system, the manufacturing cost can be reduced by reducing the number of parts, and a simplified and inexpensive electric lock system can be constructed. In addition, it is possible to avoid unauthorized locking and unlocking due to fraud from the outside, and to obtain high crime prevention. And since the freedom degree of wiring and an installation space increases, construction of various electric lock systems is realizable, without limiting installation equipment.

  In addition, since the operation indicator is configured so that an external device that outputs a signal for controlling the electric lock can be connected, not only the operation from the operation indicator but also the signal from the external device can be applied. The lock can be controlled.

The status information is output to the relay device 50 (ST40). Then, when the lock status information output from the operation indicator 20 is input (ST41), the relay device 50 converts the lock status information from a serial communication command to a LAN command (ST42), and the command is converted. Status information is transmitted to the external terminal 60 (ST43). When the external terminal 60 receives the status information transmitted from the relay device 50 via the network (ST44), the received status information is displayed on the display screen. Thereby, the resident confirms the lock / unlock state of the lock on the display of the external terminal 60.

  Next, an operation when performing the locking / unlocking operation of the electric lock 10 with a control function using the external terminal 60 will be described with reference to FIGS. 9 and 10.

  A resident locks or unlocks the relay device 50 from the outside via a network network such as the Internet or Ethernet (registered trademark) in order to lock (unlock) the lock with an external terminal 60 such as a mobile phone, a PDA, or a personal computer. A locking (unlocking) signal for instructing unlocking is transmitted (ST51). Relay device 50 receives a locking (unlocking) signal from external terminal 60 (ST52). Then, the received locking (unlocking) signal is converted from a LAN command to a serial communication command (ST53) and output to the operation display 20 (ST54). When a lock (unlock) signal is input from relay device 50 (ST55), operation indicator 20 outputs a lock (unlock) signal to main electric lock 11 (ST56). The electric lock 10 with a control function is based on the locking (unlocking) signal input from the operation indicator 20, and locks the ST11 to ST18 (see FIG. 4) and ST21 to ST25 (see FIG. 5) described above (see FIG. 5).
