Only when it is detected, the second ID code received from the first control device 51 is registered in the second ID code registration unit 56.

An example of the operation of the control circuit 50 will be described below.
(1) When unlocking the electric lock FIG. 10 shows an operation flow of the control unit 53 of the first control device 51 and the control unit 57 of the second control device 55 in this case.
FIG. 10A is an operation flow of the control unit 53 of the first control device 51. In the control unit 53, first, when the user inputs the first ID code using a magnetic card or a personal identification number, the first ID code is detected. Next, the second ID code previously registered in the second ID code holding unit 52 is read. And it authenticates whether the 1st ID code which the user input with the magnetic card, the PIN code, etc. and the code registered in the 2nd ID code holding part 52 correspond with the right thing. If the two do not match, the process ends. If the two match, the second ID code unique to the first control device 51 is read from the second ID code holding unit. Then, a second ID code unique to the first control device 51 is transmitted to the second control device 55 together with the control signal of the unlock command.

  FIG. 10B is an operation flow of the control unit 57 of the second control device 55. The control unit 57 detects the second ID code from the unlock command control signal received from the first control device 51 and the second ID code. Here, when only the control signal of the unlock command is received, the following processing is not performed and the processing is terminated. On the other hand, when the second ID code is detected together with the control signal of the received unlocking command, the detected second ID code is correctly registered in the second ID code registration unit 56 in advance. Authenticate whether it matches. Only when they match, the control signal for the electric lock is transmitted from the second control device 55, the drive source 58 is activated, and the electric lock is unlocked. That is, when the second ID code received from the first control device 51 does not match the code registered in the second ID code registration unit 56 in advance, or the second ID code is transmitted from the first control device 51. If not, the control signal for the electric lock is not transmitted from the second control device 55, and the electric lock 2 is not unlocked.

  As described above, the first control device 51 transmits the second ID code unique to the first control device 51 to the second control device 55 together with the control signal, and the second control device 55 receives the received second ID code. A control signal is sent and the drive source 58 is actuated to unlock the electric lock 2 on the condition that it matches the code registered in the second ID code registration unit 56 in advance. Therefore, even if a malicious third party sends an unauthorized control signal to the electric lock by some means such as an external input device, the second ID code is not received or even if it is received, the second ID code is not received. Since it is not valid, the control signal of the electric lock 2 is not transmitted from the second control device 55 only by the control signal, and the electric lock 2 is not unlocked. .

(2) When the old one of the first control device is replaced and the second ID code of the new control device 51 is newly registered in the second control device 55, the control unit 53 of the first control device 51 in this case and the second An operation flow of the control unit 57 of the control device 55 is shown in FIG.
FIG. 11A is an operation flow of the control unit 53 of the new first control device 51. In the control unit 53, when the transmission switch 54 is turned on, a new second ID code unique to the first control device 51 is read from the second ID code holding unit 52, and the second ID code is read from the second control device. To 55.

  FIG. 11B is an operation flow of the control unit 57 of the second control device 55. When the control unit 57 receives the second ID code from the first control device 51, the sensor unit 59 detects the locking / unlocking state of the second control device 55 and the open / closed state of the door. Then, only when the second control device 55 is in the unlocked state or the door is open, the old code registered in the second ID code registration unit 56 is rewritten with a new second ID code. Further, when the second control device 55 is in a locked state and the door is closed, the second ID code transmitted from the first control device 51 is not registered.

In this way, the second ID code received from the first control device 51 is sent to the second control device 55 only when the transmission switch 54 is turned on while the second control device 55 is unlocked or the door is open. sign up. That is, only authorized users can perform registration processing.
Therefore, even if a malicious third party sends an illegal storage command control signal from the external input device to the second control device in the locked state, the second control device 55 is in the unlocked state or the door in that case. Since the open state is not detected, even if the second ID code is received from the external input device, the second ID code cannot be registered.

(3) When the second ID code is registered in the second control device 55 at the time of initial setting The second ID code is registered in the second ID code registration unit 56 of the second control device 55 at the time of initial setting. When the control signal from the first control device 51 and the ID code (second ID code) unique to the first control device 51 are transmitted, the received second ID code Is automatically registered in the second ID code registration unit 56 of the second control device 55.

FIG. 12A shows an operation flow in the control unit 53 of the first control device 51.
At the time of initial setting, when the control unit 53 transmits a control signal, the control unit 53 reads the second ID code unique to the first control device 51 registered in the second ID code holding unit 52 and performs the second control together with the control signal. To device 55.

FIG. 12B shows an operation flow in the control unit 57 of the second control device 55.
At the time of initialization, the control unit 57 detects the second ID code from the control signal and the second ID code transmitted from the first control device 51. If only the control signal is transmitted, the process is terminated. In addition, when the second ID code is detected together with the control signal, the code is read from the second control device 55, whether or not they match is authenticated, and if they do not match, the process is terminated.

By the way, the door-side energizing device 20 is built in the electric lock 2 provided on the door end side of the door a as described above, but the door frame b facing the door-side energizing device 20 is as described above. A frame-side energization device 30 is provided in
The frame side energization device 30 will be described in detail below based on FIGS. 2, 13, and 14.

  That is, as described above, the frame-side energization device 30 is formed in a stepped box shape, and the partition 30b is formed from the front to the rear of the step 30a, and the frame side from the front to the rear of the partition 30b. A through hole 30c into which the electrode 32 is inserted is formed, and a magnet 39 is provided in a central portion of the partition wall 30b at a position facing the magnet 29 provided in the door side energization device 20.

Further, overhanging flange portions 35, 35 are formed on both upper and lower portions of the rear portion of the stepped portion 30 a, and between the back surface (rear surface) side of the overhanging flange portions 35, 35 and the bottom plate portion 91 b of the upper receiving box 91. A coil spring 36 is elastically supported. When the frame-side energization device 30 is assembled to the upper receiving box 91, the frame-side energization device 30 is inserted into the recess 91 a of the upper receiving box 91, and then the stepped portion 30 a of the frame-side energization device is inserted into the insertion hole of the seat 93. The receiving seat 93 is fixed to the door frame b with a screw or the like via the upper receiving box 91 by being freely fitted in the 93 a. As a result, the frame-side energization device 30 is normally biased forward (rightward in FIG. 14 b) by the spring force of the coil spring 36.
One end of a control panel side lead wire 31 is connected to the rear part of the frame side electrode 32.

  As described above, the frame-side energization device 30 forms the gaps S1 to S4 with the receiving part (the upper receiving box 91 and the receiving seat 93) of the other party, so that the door is opened by wind or human operation. Even in the case of rattling, the frame-side energization device 30 follows the rattling, and the frame-side electrode 32 reliably contacts the door-side electrode 22 to prevent contact failure. Since it is also slidably contacted, it also has a cleaning effect that the deposits attached to each electrode are removed.

The above effect will be described with reference to FIGS. 15 and 16. FIGS. 15A, 15B and 15C show the operation from the closed state to the opening of the door, and FIGS. 16A, 16B and 16C show the operation from the opened state to closing the door. Shows the operation.
FIG. 15A shows a state in which the door a is completely closed. In this case, the distances between the gap S3 and the gap S4 are equal.

When the door a moves in the opening direction while being normally or rattling from the closed state of FIG. 15A, the frame side electrode 32 of the frame side energizing device 30 is Since it is moved while rubbing against the door-side electrode 22, a contact failure between the electrodes 32, 32 can be prevented, and a self-cleaning effect of removing deposits adhering to the electrodes 32, 22 can be achieved. At this time, the distance of the gap S3 is reduced and is in a state of S4> S3.
Then, as shown in FIG. 15 (c), when the doors 32 and 22 are not in contact with each other, the distances of the gap S3 and the gap S4 are equal, and the above effect is lost.

When the door S is closed as shown in FIG. 16B from the state in which the distances of the gaps S3 and S4 are equal in the opened state as shown in FIG. 16A, the magnets 39 and 29 are attracted to each other. Further, when the door is further closed, the electrodes 32 and 22 are moved while rubbing against each other, so that contact failure between the electrodes 32 and 22 can be prevented and the self-cleaning effect can be achieved. At this time, the clearance S3 <S4.
When the door is completely closed as shown in FIG. 16 (c), it becomes as shown in FIG. 15 (a).

17 to 19 show modifications of the frame-side energization device 30.
In this case, the frame-side energization device 30 is obtained by changing the attachment structure of the coil spring 36 as compared with the present embodiment. That is, the overhanging flange portions 35, 35 formed in the vertical direction of the partition wall 30b of the frame-side energization device 30 are formed as thick portions as shown in FIG. A spring through hole 37 is provided toward the back side, and a coil spring 36 is inserted into the spring through hole 37.
Note that both ends of the coil spring 36 abut against the side wall of the recess 91 a of the upper receiving box 91.

  According to this configuration, there is an advantage that the attachment of the coil spring 36 is simpler than that of FIG.

Also in this case, since the gaps S1 to S4 are formed between the frame-side energization device 30 and the counterpart receiving portion (the upper receiving box 91 and the receiving seat 93), the same as in the case of the present embodiment. Have advantages.
For example, when the door hangs down due to wind or human operation, the frame-side energization device 30 is closed when the door is closed due to the attractive force between the magnets 39 and 39 with the door-side energization device 20 as shown in FIGS. ) Descent as shown. As a result, the gap S2 is closed by the stepped portion 30a of the frame-side energization device 30, and the gap S1 is expanded to the maximum distance.

Further, when the gap between the door and the window frame is reduced due to wind or human operation, the frame-side energization device 30 is arranged on the bottom plate portion 91b side of the upper receiving box 91 as shown in FIGS. 19 (b) and 19 (c). Retreat to.
In addition, the frame-side energization device 30 can move in any direction of the gaps S1 to S4.
