Used for. The fourth terminal of the parallel harness 44D is connected to a switch circuit 150 as a signal output unit. The switch circuit 150 is configured by, for example, BAN-Y.RO # (trade name, manufactured by Miwa Lock Co., Ltd.). In the switch circuit 150, the external card reader controller 50 is connected to the input side, the fourth terminal of the parallel harness 44D is connected to the output side, and power is supplied from the U harness 42D. Reference numeral 151 denotes a connector.

  Here, when the external card reader controller 50 is made, that is, when the card is verified by the external card reader controller 50 from the state where the door A 10 is unlocked, the output side of the switch circuit 150 becomes 0 V, and the parallel harness The 4th terminal of 44D becomes 0V (Low). Further, when the card is verified by the external card reader controller 50 from that state, that is, when a break occurs, the output side of the switch circuit 150 becomes a predetermined voltage (for example, 24V), and a predetermined voltage is applied to the fourth terminal of the parallel harness 44D. A voltage is applied.

  The selection unit 470 includes a first short-circuit terminal 471, a second short-circuit terminal 472, and a third short-circuit terminal 473. The selection unit 470 uses the short-circuit pin 46 to short-circuit the first short-circuit terminal 471 and the second short-circuit terminal 472 or to short-circuit the second short-circuit terminal 472 and the third short-circuit terminal 473. It can be selected exclusively. As shown in FIG. 3, such setting of the short-circuit pin 46 can be recognized visually by a person from the front.

  The relays 45A to 45C are connected on the input side to the third short-circuit terminal 473 in the selection unit 470 via the diode D1, and are opened and closed between the second terminal and the third terminal of the parallel harnesses 44A to 44C on the output side. Switch. That is, when a predetermined voltage is applied to the line 47, a voltage is applied from the line 47 to the relays 45A to 45C via the second short-circuit terminal 472, the short-circuit pin 46, and the third short-circuit terminal 473, and the relays 45A to 45C. 45D is turned ON, the space between the second terminal and the third terminal of the parallel harnesses 44A to 44C is released, and the electric lock 20 connected to the line 30 is unlocked. On the other hand, when the line 47 becomes 0V, the relays 45A to 45C become 0V from the line 47 via the second short-circuit terminal 472, the short-circuit pin 46, and the third short-circuit terminal 473, and the relays 45A to 45D are turned OFF, and the parallel harness The space between the second terminal and the third terminal of 44A to 44C is closed, and the electric lock 20 connected to the line 30 is locked.

  The first short-circuit terminal 471 is connected to the fourth terminal of the parallel harnesses 44A to 44D via the diode D2.

It is set to be High when the door 10 of the electric lock 20 is opened, and Low when the door 10 is closed. Accordingly, the first short-circuit terminal 471 is set to be high when the door 10 is opened, and the first short-circuit terminal 471 is set to be low when the door 10 is closed.

  In this embodiment, as shown in FIG. 3, when the A door is opened, the B door and the C door are closed, and when the B door is opened, the C and A doors are closed and the C door is opened. The short-circuit pin 46 is short-circuited in the selection unit 470 so that the door A and the door B are closed.

  In the present embodiment, in order to perform locking and unlocking from the outside, the second short-circuit terminal 472 corresponds to the four line portions where no line is set, and in the first to third selection units 470 from the bottom. The first short-circuit terminal 471 is short-circuited by the short-circuit pin 46.

In this state, for example, A door 10 of the electric lock 20 which corresponds to one line _{30 -1} is the door opening, the first short-circuit terminal 471 becomes High in 1 line _{30 -1,} through a shorting pin 46 to The second short-circuit terminal 472 connected in this manner becomes High, and the second and third lines 47 from the bottom become High. Thus, a predetermined voltage is applied to the two-line _{30 -2}及3 lines _{30 -3,} relay 45B and the relay 45C is turned ON, between the pin 2 and pin 3 of the parallel harness 44B and 44C become released is an electric lock 20 is unlocked two circuits _{30 -2}及3 lines ₃₀ connected B door and C door 10 to _-3.

On the other hand, the A door 10 of the electric lock 20 which corresponds to the example 1 line _{30 -1} When closing, the first short-circuit terminal 471 becomes Low in 1 line _{30 -1,} is connected via the shorting pin 46 to The second short-circuit terminal 472 becomes Low, and the second and third lines 47 from the bottom become Low (0 V). Thus, two circuits _{30 -2}及3 lines _{30 -3} and becomes Low, relays 45B and 45C are OFF, between the pin 2 and pin 3 of the parallel harness 44B and 44C become closed, two-line 30 _-2及3 line ₃₀ electric lock 20 of the connected B door and C door 10 _-3 is locked.
Interlock control is similarly performed for the opening and closing of the doors B and C.

Here, when the external card reader controller 50 is made, that is, when the card is verified by the external card reader controller 50 from the state where the door A 10 is unlocked, the output side of the switch circuit 150 becomes 0 V, and the parallel harness The 4th terminal of 44D becomes 0V (Low). As a result, the first to third lines 47 from the bottom become Low (0 V), the relays 45A to 45C are turned OFF, and the connection between the second and third terminals of the parallel harnesses 44A to 44C is closed. electric lock 20 of the a door ~C door 10 connected to the line ₃₀ -1 to 3 lines _{30 -3} is locked.

When the card is verified by the external card reader controller 50 from the locked state as described above, that is, when the card is broken, the output side of the switch circuit 150 becomes a predetermined voltage (for example, 24 V), and the parallel harness 44D 4 A predetermined voltage is applied to the terminal. As a result, the first to third lines 47 from the bottom become High (predetermined voltage), the relays 45A to 45C are turned ON, and the space between the second and third terminals of the parallel harnesses 44A to 44C is opened. is an electric lock 20 is unlocked in a door ~C door 10 connected to a line ₃₀ -1 to 3 lines _{30 -3.}

FIG. 4 is a diagram showing an example of daytime operation in such a system.
Normally, all the doors (A door to C door 10) are unlocked during standby (when all of the doors A, B, and C are closed) (FIG. 4 (a)). This is the initial state.
Here, when the A door 10 is opened, the B door 10 and the C door 10 are locked (FIG. 4B). When the door A 10 is closed from this state, the state returns to the initial state.
Moreover, when the B door 10 is opened, the A door 10 and the C door 10 are locked (FIG. 4C). When the door B is closed from this state, the state returns to the initial state.
Similarly, when the C door 10 is opened, the A door 10 and the B door 10 are locked (FIG. 4D). If C door 10 is closed from this state, it will return to an initial state.
When the operation panel 40 receives a fire signal from a predetermined alarm (not shown) or the like, the operation panel 40 is unlocked all at once and the interlock control is not performed (FIG. 4 (e)). For example, when the fire signal is cut off and all the doors (A door to C door 10) are closed, the control returns to the interlock control.

FIG. 5 is a diagram showing an example of night operation in such a system.
During night operation, when the card 152 is collated by the external card reader controller 50, all the doors (A door to C door 10) are locked all at once, and the interlock control is stopped (FIG. 5A).
When the card 152 is verified again by the external card reader controller 50 from this state, all the doors (A door to C door 10) are simultaneously unlocked, and the initial state in the daytime operation shown in FIG. Returning to FIG. 5 (b).

  Therefore, in the interlock system according to the present embodiment, it is not necessary to check the locking of each of the plurality of doors to be interlocked one by one, and the doors can be locked and unlocked all at once from the outside, for example. Therefore, for example, when the card reader is passed through at the final exit such as at night, all the doors that are interlock controlled are locked. Since the door controlled by the interlock is an external door, security can be secured by being able to lock regardless of the interlock control. Further, even if the interlock-controlled door is not an external door, this system contributes to ensuring security because it is not necessary to check the locking of each internal door.

  In the interlock system according to the present embodiment, the door can be locked and unlocked all at once from the outside using a conventional general-purpose interlock substrate, so that the configuration is very simple.

  Furthermore, as shown in FIG. 3, interlock control or the like can be arbitrarily set using a short-circuit pin in the selection unit, and such a short-circuit pin setting can be visually recognized from the front by a person. Therefore, the setting pattern including the interlock control and the like can be easily grasped, and the setting pattern can be easily changed.

  It should be noted that the present invention is not limited to the above-described embodiment, and can be appropriately modified within the scope of the technical idea of the present invention, and the scope of the implementation also falls within the technical scope of the present invention. It belongs to.
