  That is, the non-contact key 2 does not need a battery and is composed of an RF tag and a display that operate using radio waves generated by non-contact communication from the electric lock device 3 as an energy source. When a part is reflected by the antenna of the tag, authentication information (ID information) for instructing locking or unlocking of the electric lock 33 of the electric lock device 3 is put on the reflected wave and returned to the electric lock device 3 ing.

  As shown in FIG. 1, the non-contact key 2 includes an authentication information storage unit 21, a transmission / reception unit 22, a control unit 23, and a display unit 24 as an internal configuration.

  The authentication information storage unit 21 stores ID information for instructing locking or unlocking of the electric lock 33 of the electric lock device 3 as authentication information.

  The transmitter / receiver 22 brings the non-contact key 2 close to the communicable area of the electric lock device 3, and when the non-contact key 2 is activated by power supply by non-contact communication with the electric lock device 3, Information is transmitted to and received from the transmission / reception unit 31 by non-contact communication.

  The control unit 23 controls each part of the non-contact key 2 and has a display control means 23a.

  The display control means 23a is an operation display command (locking operation display command or unlocking operation) from a display command control means 34c (to be described later) of the electric lock device 3 in the non-contact communication between the non-contact key 2 and the electric lock device 3. The display unit 24 is turned on or off or the voltage level is controlled based on the display command.

  The display unit 24 is configured by, for example, a liquid crystal display, and identifies and displays the final operation content when the user performs a locking operation or an unlocking operation using the non-contact key 2. The display unit 24 is controlled to be turned on / off by the display control unit 23a of the control unit 23 based on an operation display command (locking operation display command or unlocking operation display command) from a display command control unit 34c described later of the electric lock device 3. Alternatively, the voltage level is controlled.

  As the display unit 24, a cholesteric liquid crystal reflecting only a specific wavelength (light) is used, and the helical axis of the liquid crystal molecule is stabilized in the vertical direction or the horizontal direction. It is preferable to adopt a cholesteric liquid crystal display having a memory property that maintains the orientation of

  When a cholesteric liquid crystal display is used as the display unit 24, the display control unit 23a based on an operation display command (locking operation display command or unlocking operation display command) from a display command control unit 34c described later of the electric lock device 3 is used. Controls the voltage level applied to the transparent electrodes before and after each liquid crystal layer (red liquid crystal layer, green liquid crystal layer, blue liquid crystal layer) on the light absorption layer, and switches the presence or absence of reflection by changing the direction of the liquid crystal molecules ing.

  Here, when the operation content (locking operation and unlocking operation) by the non-contact key 2 is identified and displayed by turning on / off, the display unit 24 is displayed when a locking operation display command is input from the display command control means 34c described later. Turns on and lights up. When an unlocking operation display command is input from the display command control means 34c, the display unit 24 is turned off and turned off.

  In addition, when the operation content of the non-contact key 2 is color-coded and displayed for identification, a cholesteric liquid crystal display is used as the display unit 24 and the voltage level of the display unit 24 is controlled to control the display command control means 34c described later. When the locking operation display command is input, the display unit 24 is lit in red, for example, and when the unlocking operation display command is input from the display command control unit 34c, the display unit 24 is lit in green, for example.

  If a cholesteric liquid crystal display is used as the display unit 24 and the cholesteric liquid crystal display is controlled to be turned on / off or voltage level controlled by the display control unit 23a, the user locks or unlocks the electric lock 33. The final operation content can be identified and displayed, and the display content can be held even in a non-powered state with the voltage turned off.

  As shown in FIG. 1, the electric lock device 3 includes a transmission / reception unit 31, a state monitoring unit 32, an electric lock 33, a control unit 34, and a power supply unit 35.

  The transmission / reception unit 31 performs transmission / reception of information by non-contact communication with the transmission / reception unit 22 of the non-contact key 2 when the user brings the non-contact key 2 close to the communicable area of the electric lock device 3. Yes.

  The state monitoring unit 32 includes various detection sensors such as a micro switch and a reed switch, and monitors the locking / unlocking state of the electric lock 33 and the opening / closing state of the door. The monitoring result by the state monitoring unit 32 is sequentially transmitted to the control unit 34 as a state signal (locking / closing, unlocking / closing, locking / opening, unlocking / opening).

  The electric lock 33 is locked or unlocked by controlling energization of the drive means such as a motor or solenoid by the drive control means 34b and moving the dead bolt connected to the drive means forward and backward with respect to the engagement hole of the door frame. It consists of a well-known mechanism to be locked.

  The electric lock 33 may be configured so that the lock and unlocking of the lock is electrically controlled by the drive control means 34b of the control unit 34, and the structure is not limited.

  The control unit 34 controls each part of the electric lock device 3 and has a determination unit 34a, a drive control unit 34b, and a display command control unit 34c.

  In the discriminating means 34 a, information for permitting the locking or unlocking of the electric lock 33 is registered in advance as collation information, and the collation information and the transmission / reception unit 31 are contactless from the transmission / reception unit 22 of the non-contact key 2. The authentication information acquired by communication is collated to determine the validity of the authentication information, that is, whether or not the authentication information matches the verification information.

  When the authentication unit 34a successfully authenticates the authentication information, the determination unit 34a outputs a command signal (locking command signal or unlocking command signal) corresponding to the state signal from the state monitoring unit 32 to the drive control unit 34b. That is, if the state signal from the state monitoring unit 32 is unlocked / closed, the determination unit 34a outputs a locking command signal to the drive control unit 34b. On the other hand, if the state signal from the state monitoring unit 32 is locked / closed, the determination unit 34a outputs an unlock command signal to the drive control unit 34b.

  When the lock command signal is input from the discriminating means 34a, the drive control means 34b drives the electric lock 33 to be locked. Specifically, the drive means such as a motor or an actuator is energized, and a dead bolt connected to the drive means is engaged with the engagement hole of the door frame and locked. In addition, when the unlock command signal is input from the determination unit 34a, the drive control unit 34b drives to unlock the electric lock 33. Specifically, the drive means such as a motor or an actuator is turned off, and the dead bolt connected to the drive means is retracted from the engagement hole of the door frame and unlocked.

  The display command control means 34c identifies and displays on the display unit 24 of the non-contact key 2 that the lock operation by the non-contact key 2 has been performed when the determination means 34a outputs a lock command signal to the drive control means 34b. The locking operation display command indicating the locking operation content is output to the transmission / reception unit 31. Further, the display command control means 34c notifies the display unit 24 of the non-contact key 2 that the unlocking operation has been performed by the non-contact key 2 when the determination means 34a outputs the unlock command signal to the drive control means 34b. In order to display the identification, the unlocking operation display command indicating the unlocking operation content is output to the transmission / reception unit 31.

  The power supply unit 35 is supplied with building commercial power (for example, AC 100 V), and supplies necessary drive power to each part of the electric lock device 3 based on the commercial power.

  Next, as an operation of the electric lock system 1 configured as described above, a case where the electric lock 33 is locked using the non-contact key 2 will be briefly described with reference to FIG.

  When the non-contact key 2 is moved close to the communicable area of the electric lock device 3 to lock the electric lock 33 (ST1), non-contact communication by electromagnetic induction is performed between the non-contact key 2 and the electric lock device 3. It is started (ST2). And the transmission / reception part 31 of the electric lock apparatus 3 acquires authentication information from the non-contact key 2 by non-contact communication between the transmission / reception part 22 of the non-contact key 2 (ST3).

  Subsequently, the discriminating means 34a of the control unit 34 in the electric lock device 3 collates the authentication information acquired by the transmitting / receiving unit 31 with the collation information registered in advance, and discriminates the validity of the authentication information (ST4). If the authentication unit 34 normally authenticates the authentication information, the determination unit 34a outputs a locking command signal to the drive control unit 34b (ST5). Then, when the locking instruction is input from the determination unit 34a, the drive control unit 34b locks the electric lock 33 (ST6).

  Simultaneously with the authentication information collation determination processing, the display command control means 34c of the control unit 34 in the electric lock device 3 causes the determination means 34a to normally authenticate the authentication information and output a lock command signal to the drive control means 34b. Then, a lock operation display command for identifying and displaying the operation content indicating that the electric lock 33 is locked by the non-contact key 2 is transmitted from the transmission / reception unit 31 to the non-contact key 2 (ST7).

  Then, the transmission / reception unit 22 of the non-contact key 2 receives the locking operation display command from the transmission / reception unit 31 of the electric lock device 3 and sends it to the display control means 23a of the control unit 23 (ST8). When the locking operation display command is input, the display control means 23a regards the operation instruction (locking) as to the electric lock 33 and identifies on the display unit 24 that the electric lock 33 has been locked by the non-contact key 2. For example, the display unit 24 is turned on to control lighting (ST9).

  The processing operation described above is for the case where the electric lock 33 is locked by the non-contact key 2. However, when the electric lock 33 is unlocked by the non-contact key 2, the non-contact key 2 is used. For example, the display unit 24 is turned off so that the electric lock 33 can be distinguished from the locked state. Or the voltage level of the display part 24 is controlled and the display part 24 is color-coded, and the case where the electric lock 33 is locked and unlocked by the non-contact key 2 is identified and displayed.

  Thus, in the electric lock system 1 according to the present invention, when the non-contact key 2 is brought close to the communicable area of the electric lock device 3 by electromagnetic induction, the non-contact key 2 is activated by electromagnetic induction from the electric lock device 3. Then, non-contact communication is performed between the non-contact key 2 and the electric lock device 3, and the final operation content (locking operation and unlocking operation) is locked on the electric lock 33 based on a command from the electric lock device 3. Alternatively, since the non-contact key 2 includes the display unit 24 for identifying and displaying in conjunction with unlocking, even when the electric lock (lock) 33 is locked or unlocked by an electric operation, the user performs his / her own actions. The final operation content can be reliably recognized on the display unit 24 of the non-contact key 2.

  Further, the non-contact key 2 is composed of an RF doug that operates using radio waves generated by non-contact communication from the electric lock device 3 as an energy source when it is brought close to the communicable area of the electric lock device 3. It is not necessary to equip a power supply unit such as the key 52 of Patent Document 1, it can be thinned, and the user is not bulky when carrying it.

  Furthermore, if a cholesteric liquid crystal display is used as the display unit 24 and the on / off control or voltage level control of the cholesteric liquid crystal display is performed according to the operation content (locking operation, unlocking operation) of the non-contact key 2, the user can The final operation content can be identified and displayed, and the display content can be held even in a non-powered state.
