The detecting means on the auxiliary lock body 3 side is composed of switches 13A and 13B, but a reed switch for detecting the permanent magnets 8A and 8B, or a transmitting element for detecting a response radio wave by sending a radio wave to the loop antenna. In addition, it may be either a receiving element, a reflective interrupter that reads reflected light by irradiating light to a reflecting mirror, or a reading device that reads an identification mark.

  The auxiliary lock body 3 includes a metal cylindrical holding member (not shown) that holds the dead bolt 6 slidable in the longitudinal direction and immovable in the orthogonal direction, and a reduction gear mechanism for sliding the dead bolt 6 in the longitudinal direction. Alternatively, a drive mechanism (not shown) including a link mechanism, a motor M for driving the drive mechanism, a battery 9 that supplies power to the motor M, a microcomputer 10 that is supplied with power from the battery 9, and indoor centralized monitoring control. And a communication module 12 including a communication element and a CODEC element for transmitting and receiving a locking command, an unlocking command, and a monitoring command from the apparatus 11.

  The auxiliary lock body 3 includes switches 13A and 13B that are attracted and conducted by the permanent magnets 8A and 8B, a home position switch 14 that detects a position when the dead bolt 6 is on standby or unlocked, and a dead bolt 6 An insertion confirmation switch 15 for detecting the position of the dead bolt 6 when properly inserted into the keyhole 7 is provided. The dead bolt 6 includes a protrusion 6A for turning on the switch 15. The holding member (not shown) and the key hole 7 have a shape that can pass through the protrusion 6A. The dead bolt 6 includes a protrusion 6B for turning on the switch 14, and the holding member has a shape that can pass through the protrusion 6B.

  A relay element 16 is provided between the motor M and the battery 9 to control forward / reverse rotation by changing the direction of the current. The relay element 16 controls the rotation direction of the motor M under the control of the microcomputer 10. Control.

  The communication module 12 includes an antenna 17 for performing wireless communication with the centralized monitoring control device 11 and is supplied with power from the battery 9.

  The microcomputer 10 receives the “locking command signal”, the “monitoring command signal”, the “unlocking command signal”, or the “opening / closing state confirmation command signal” of the door from the centralized monitoring control device 11, and switches 13A, 13B, 14 and 15 are detected, and forward / reverse rotation control of the motor M or the like is performed.

  In other words, the centralized monitoring control device 11 locks the building, monitors the locking, and unlocks the building, and is connected via a home phone that can be connected to the mobile phone 20. It has a communication function for performing data communication with the telephone 20. The centralized monitoring and control apparatus 11 includes a lock button 11A, a monitor button 11B, an unlock button 11C, and a warning lamp 19, and also includes a “door open / close state confirmation command”, “lock command”, “monitor command”, or “unlock”. A communication program for transmitting the “command” to the auxiliary lock 1 is provided.

  When the centralized monitoring and control device 11 outputs the “open / close state confirmation command signal” of the door 4 from the antenna 11D, when the communication module 12 receives this “door open / close state confirmation command signal” via the antenna 17, the communication module 12 This “door open / close state confirmation command signal” is converted into a bit code and transmitted to the microcomputer 10.

  The microcomputer 10 activates the door opening / closing state confirmation program based on the “door opening / closing state confirmation command signal”, and determines whether the door 4 is properly closed with the object P not in a state of being caught in a gap or the like ( Check that the door is closed.

  This door open / close state confirmation program confirms whether or not the switches 13A and 13B are attracted by the permanent magnets 8A and 8B and are conducted.

  If the switches 13A and 13B are conductive, it is judged that the door 4 has properly closed the entrance P, and the “appropriate closing information” that the door 4 has been properly closed is converted to analog and centralized monitoring is performed. It transmits to the control apparatus 11. Upon receiving the “appropriate closing information”, the centralized monitoring control device 11 displays, for example, “The entrance door is closed” on the liquid crystal display panel 18.

  If the switches 13A and 13B are not conductive, it is determined that the door 4 does not close the entrance P, and “door opening information” is transmitted from the communication module 12 to the centralized monitoring controller 11 via the antenna 17. Upon receiving the “door opening information”, the centralized monitoring control device 11 displays, for example, “The entrance is open” on the liquid crystal display panel 18.

  Similarly, when the centralized monitoring control device 11 outputs the “locking command signal” for the door 4, when the communication module 12 receives this “locking command signal” via the antenna 17, the communication module 12 receives the “locking command signal”. Is converted into a bit code and transmitted to the microcomputer 10. The microcomputer 10 activates the locking program based on this “locking command signal”. This locking program first activates the door open / closed state confirmation program to determine whether the door 4 is properly closed (not locked) as to whether the door 4 is not in a state where an object is caught in a gap or the like. Check the status.

  If the door 4 is not properly closed in the door closing confirmation, a display such as “the entrance is open” is displayed on the liquid crystal display panel 18 and the warning lamp 19 of the centralized monitoring control device 11 blinks. And waits for the user to close the door 4.

  When the door 4 is properly closed, the locking program rotates the motor M forward and inserts the dead bolt 6 into the key hole 7. Whether or not the amount of entry of the dead bolt 6 into the keyhole 7 is appropriate is determined by turning on the insertion confirmation switch 15.

  If the switch 15 is turned on within a predetermined time, the microcomputer 10 determines that the dead bolt 6 has been properly inserted into the keyhole 7, and transmits the result to the centralized monitoring control device 11 as "locking complete". The centralized monitoring control device 11 receives the “locking completion information” and displays, for example, “locking” on the liquid crystal display unit 18.

  If the switch 15 is not turned on within a predetermined time, the microcomputer 10 determines that the dead bolt 6 has not been properly inserted into the keyhole 7, and transmits the result to the centralized monitoring control device 11 as "locking incomplete". . The centralized supervisory control device 11 receives the “unlocked information” and displays on the liquid crystal display unit 18, for example, “cannot be locked”, and blinks the warning lamp 19 of the centralized supervisory control device 11 for use. Wait for the person to close the door 4.

  The monitoring program is automatically started after execution of the locking program. The processing content of this monitoring program is that the door open / closed state confirmation program is periodically started on the condition that the locking program has been executed, and whether the door 4 is properly closing the entrance P or not. Confirm. After confirmation, the confirmation result is transmitted to the centralized monitoring control apparatus 11. When the door 4 is opened despite being “locked”, the centralized monitoring control device 11 blinks the alarm lamp 19, communicates with a security company or the like, or transmits an alarm to the mobile phone 20. For example, after the door 4 has properly closed the entrance P, the switches 13A and 13B are in an ON state, and the home position switch 14 is turned on even after a predetermined time has elapsed after the insertion confirmation switch 15 is turned off. If not, the alarm lamp 19 blinks because it is not a regular unlocking.

  When the centralized monitoring control device 11 receives a lock state confirmation command from the mobile phone 20 or the like, the centralized monitoring control device 11 outputs a “monitoring command signal” of the door 4 to the auxiliary lock 1. In this case, the microcomputer 10 activates the monitoring program based on this “monitoring command signal”.

  This monitoring program starts the door open / close state check program periodically on condition that the dead bolt 6 is inserted into the keyhole 7 when the locking program is finished, and the door 4 properly closes the entrance P. Check if the door is closed. Then, the confirmation result is transmitted to the centralized monitoring control apparatus 11, and the centralized monitoring control apparatus 11 transmits the confirmation result information to the mobile phone 20.

  Similarly, when the centralized monitoring control device 11 outputs an unlock command signal for the door 4, when the communication module 12 receives the “unlock command signal” via the antenna 17, the communication module 12 receives the “unlock command signal”. Is converted into a bit code and transmitted to the microcomputer 10. The microcomputer 10 activates the unlocking program based on the “unlock command signal”. In this unlocking program, the motor M is rotated in the reverse direction and the dead bolt 6 is removed from the keyhole 7. Whether or not the dead bolt 6 has been completely removed from the keyhole 7 is determined by turning on the switch 14.

  If the switch 14 is turned on within a predetermined time, the microcomputer 10 determines that the dead bolt 6 has been properly removed from the keyhole 7, and transmits the result to the centralized monitoring control device 11 as the unlocking completion. The centralized monitoring control device 11 receives the “unlocking completion information” and displays “Unlocking” on the liquid crystal display unit 18.

If the switch 14 is not turned on within a predetermined time, the microcomputer 10 determines that the dead bolt 6 has not been properly removed from the keyhole 7, and transmits the result to the centralized monitoring control device 11 as unlocking incomplete. The centralized monitoring control device 11 receives the “ unlocked incomplete information” and displays “ unlocked incomplete” on the liquid crystal display unit 18.

  When an unlocking command is transmitted from the mobile phone 20 or the like to the centralized monitoring control device 11, the “unlocking command signal” for the door 4 is output from the centralized monitoring control device 11 side to the microcomputer 10. The microcomputer 10 activates the unlocking program based on the “unlock command signal”.

  If the switch 14 is turned on within a predetermined time, the unlocking program transmits the result to the centralized monitoring control device 11 as the unlocking completion. The centralized monitoring control device 11 receives the “unlocking completion information” and displays “Unlocking” on the liquid crystal display unit 18 and also displays “Unlocking completed” on the mobile phone 20.

  On the contrary, if the switch 14 is not turned ON within a predetermined time, the microcomputer 10 transmits “unlocking incomplete information” to the centralized monitoring control device 11. The centralized monitoring control device 11 receives the “unlocked incomplete information” and displays “unlocked incomplete” on the liquid crystal display unit 18 and also displays “unlocked incomplete” on the mobile phone 20.

  As described above, since the permanent magnets 8A and 8B as the detection means are provided on the metal fitting 5 and the switches 13A and 13B as the detection means are provided on the auxiliary lock body 3, the door 4 can be opened and closed even when the lock is not being locked. The state can be easily detected in the room by detecting the state, and there is a convenience that it is not necessary to walk around to confirm the locked state of each opening. Moreover, since the appropriate position (insertion position) of the receiving metal fitting 5 and the dead bolt 6 can be easily detected, the configuration on the auxiliary lock body 3 side can be simplified.

  Furthermore, since it is electrically locked when it is used as an auxiliary lock for the front door 4, it can prevent intrusion such as so-called “picking” and “destruction of the key by a drill” and can be easily attached later. There is an advantage that it is not necessary to replace the main lock of the door 4.
