Is unlocked by projecting (locking) or pulling (unlocking) a dead bolt into the locking hole of the door frame.

  Next, an operation example of the electric lock system 1 described above will be described with a specific example. Here, the above-described electric lock system 1 is employed in an apartment house such as a general house or a condominium, for example, and a mobile phone having a videophone function is used as the external terminal 10 and the remote control robot 20 is operated by this mobile phone. An example in which the unlocked state of the electric lock 60 and the open / closed state of the door 70 are monitored from the outside and the electric lock 60 in the unlocked state is locked will be described as an example.

  When a resident who lives in an apartment house such as a general house or a condominium monitors the unlocking / unlocking state of the electric lock 60 and the opening / closing state of the door 70 from the outside, the remote control robot 20 placed first in the room is first used. In order to operate, a call is made to the remote control robot 20 with a mobile phone. Thereby, terminal identification information (for example, a predetermined telephone number) is transmitted from the mobile phone to the remote control robot 20. The remote control robot 20 determines whether the received telephone number is terminal identification information registered in advance. Then, if the remote operation robot 20 recognizes that the transmitted terminal identification information is information registered in advance as a result of the determination, the remote operation robot 20 drives the imaging means 22 to start imaging the current indoor situation.

  The resident operates the buttons based on the image picked up using the videophone function of the mobile phone, and guides the remote control robot 20 to the predetermined range of the robot operation display 30 by remote control. Then, the resident guides and moves the remote control robot 20 to the front of the robot operation display 30 by remote control from the mobile phone, and then displays the robot operation display 30 on the imaging means 22 of the remote control robot 20. The display content of the means 33 is imaged, and the current locking / unlocking state of the electric lock 60 and the open / closed state of the door 70 are confirmed from the display content. At this time, the robot operation indicator 30 detects that the remote operation robot 20 has approached within a predetermined range, and outputs a proximity detection signal indicating that the remote operation robot 20 has been detected to the control means 35.

  Then, as a result of the resident confirming the display content (in FIG. 3, the display of the door is extinguished and the unlocking display is lit / flashing), the door 70 is closed but the electric lock 60 is locked. You can see that it is not. Therefore, in order to lock the electric lock 60 from the outside, a button operation is performed so as to emit light for locking by operating the mobile phone, and the light emitting means 23 of the remote control robot 20 is driven. As a result, the robot operation indicator 30 detects the locking light emitted from the light emitting means 23 by the light detecting means 32 and outputs a light detection signal corresponding to the type of the light to the control means 35.

  When both the proximity detection signal from the proximity detection means 31 and the light detection signal from the light detection means 32 are input, the robot operation indicator 30 receives a command signal (here) Then, the lock control signal) is output to the electric lock control panel 50. Then, the electric lock control panel 50 drives and controls the electric lock 60 based on the lock control signal input from the robot operation indicator 30 and locks the electric lock 60.

  By the way, in the above-described embodiment, the robot operation indicator 30 instructs the electric lock control panel 50 on the condition that the remote control robot 20 is in the proximity state and that the light emission means 23 is illuminated. The case where the lock control signal is output as a signal and the electric lock control panel 50 receiving the lock control signal controls the lock of the electric lock 60 has been described as an example. However, the operation is not limited to this operation. For example, the electric lock control is performed by changing the illumination irradiation conditions (for example, wavelength, color, blinking method, lighting time, etc.) by the light emitting means 23 on condition that the remote control robot 20 is in the proximity of the robot operation indicator 30. It is also possible to output an unlock control signal as a command signal to the panel 50 to control the unlocking of the electric lock 60. Further, in the electric lock system 1 of this example, the state monitoring by the robot operation indicator 30 described above allows the remote operation from the external terminal 10 when the electric lock 60 is closed although the electric lock 60 is locked. If the electric lock 60 is unlocked via the remote control robot 20, the door can be automatically closed by a door closer installed on the door. Then, after that, by closing the electric lock 60 via the remote operation robot 20 by remote operation from the external terminal 10 again, it is possible to eliminate the door when the electric lock 60 is locked.

  As described above, the electric lock system 1 described above is used for a dedicated robot that remotely controls the indoor remote control robot 20 using the external terminal 10 registered in advance and takes an image with the imaging function of the remote control robot 20. The current locking / unlocking state of the electric lock 60 and the open / closed state of the door 70 are monitored from the display content of the operation indicator 30, and the unlocking (or unlocking) control of the electric lock 60 is performed as necessary. Thereby, it is possible to easily monitor and confirm the locking / unlocking state of the electric lock 60 and the open / closed state of the door 70 even from a remote location only by operating the external terminal 10, and the locking / unlocking control of the electric lock 60 according to the monitoring state can be performed. It can be carried out. As a result, the electric lock system is highly convenient, excellent in crime prevention, and can be constructed and operated without adding any special additional functions to the remote control robot. A system can be realized.
