[

In this embodiment, in implementing the emergency door locking system 1, as shown in FIGS. 1 and 2, a fire is detected through a smoke detector 410 installed at each site of a building, and a fire signal is controlled The control unit 240 of the control terminal 200 connects the fire re- ception unit 400 to the terminal 200. When the fire signal is received from the fire re- ception unit 400, The lock state of the emergency door is automatically released.

With this configuration, the emergency door that is normally restricted by the lock control module 100 and that controls the entry / exit of unspecified persons is automatically unlocked in the event of a fire, so that evacuation through the emergency exit is possible.

In particular, since the lock control module 100 of the electromagnetic lock type automatically releases the lock state of the emergency door when the starting current is interrupted, when the lock control module 100 fails or the supply of the starting current is not smooth, The lock of the door is automatically released, so that it has improved fire safety.

The control terminal 200 is further provided with a log file generation and recording unit 250 for generating and recording a log file in which the lock completion signal and the open signal output from the restraint module 120 are collected by time, Through the reading of the memory 251, it is possible to check the entrance / exit state of the emergency inquiry and the opening / closing state of the emergency inquiry.

In addition, in the present embodiment, the control terminal 200 is provided with a field notification unit 260 for on-site notification of on-off signals received through the open / close signal receiving unit 230, Receiving unit 270 is provided so that the lock status information including the lock and unlock of the emergency call by the lock control module 100 can be accurately recognized in real time by the field manager located in the field and the field staff located in the control room do.

According to the present embodiment, the field announcement unit 260 is a voice announcement type that notifies a field manager located at the field through voice by using an open signal and a lock completion signal. And notifies the administrator at the site in real time whether or not the emergency inquiry is locked according to the lock situation signal received through the terminal.

Then, the situation management device 300 pairs the smart phone 310 through a short-distance communication method such as Bluetooth or the like to allow the status management device 300 to remotely check the lock status information transmitted through the smart phone .

2 to 3 and FIGS. 5 to 7, when the door frame F is attached to the restraint unit 120 of the lock control module 100 in the embodiment of the present invention, A lock attempt detector 124 for generating a lock attempt signal of the emergency door D by interference with the emergency door D entering the door frame or the fixed unit 110 installed on the emergency door D entering the door frame, And a lock attempt signal output terminal 123d for outputting a lock attempt signal generated by the lock attempt detection unit 124 to the control terminal 200 is provided in the terminal unit 123. [

If the lock completion signal is not received during the set time after the emergency door D enters the door frame F and the lock attempt detection unit 124 detects the lock attempt of the lock, Is recognized as incomplete locked state, and it is notified in real time to a field manager located in the field and a situation worker located in the situation room.

8, the control terminal 200 controls the locking signal detection unit 124 by the fixed unit 110 fixed to the emergency door D or the emergency door to enter the door frame, When the lock completion signal is received in the restraint unit 120 within the set time after the signal is received, the locked state is audibly or visually notified to the field through the field notification unit 260, and the wireless transmission / To the situation management device 300 located in the situation room.

However, if the locking attempt detection unit is pressed by the fixed unit fixed to the emergency door or the emergency door entering the door frame and the locking signal is received and the locking signal is not received in the locking unit within the set time, the incomplete locking state Notifies the field audibly or visually through the field notification unit, and wirelessly transmits the notification to the situation management unit located in the situation room through the wireless transmission / reception unit.

If the lock attempt signal is not received by the lock attempt output terminal, the control terminal cuts off the start current supplied to the restraining unit through the start current output unit, and when the lock attempt signal is received by the lock attempt output terminal, And supplies the starting current to the restraining unit through the output unit. Thus, unnecessary consumption of the starting current is prevented by interrupting the supply of the starting current when the lock attempt is not made, that is, the emergency door is not entered into the door frame.

As shown in FIG. 3A and FIGS. 5 to 7, the lock attempt detecting unit 124 proposed in the preferred embodiment of the present invention includes a retractable rod 124a provided in a retractable structure in the restricting unit 120; A tangential spring 124b for urging the forward / backward rod 124a forward; And a sensing switch member 124c disposed at the rear of the moving rod 124a.

When the retractable rod is retracted by the urging of the emergency door (D) entering the door frame (F) or the fixed unit fixed to the emergency door (D), the detection attempting member And outputs a lock attempt signal to the control terminal 200.

The lock attempt detection unit 124 is pressed by the fixed unit 110 fixed to the emergency door D or the emergency door D to enter the door frame F and the set time The control terminal 200 audibly or visually informs the field through the on-site notifying unit 260 that the lock-up completion signal is normally received, And transmits it to the management apparatus 300 by radio.

However, after the lock attempt detection unit 124 is pressed by the fixed unit 110 fixed to the emergency door D or the emergency door D to enter the door frame F to receive the lock attempt signal, If the lock completion signal is not normally received within the time, the control terminal 200 audibly or visually notifies the incomplete lock signal through the field notifying unit 260, and transmits the incomplete lock signal through the wireless transmitting / Notify the worker in real time.

That is, when the emergency door D is opened and an open signal is received from the restraining unit 120, the control terminal 200 notifies the field manager with the message "Emergency door is normally opened" The control terminal 200 cuts off the supply of the starting current supplied to the restraining unit 120 and transmits the restraining force to the restraining unit 120. In this case, Unnecessary driving of the motor 120 is prevented and unnecessary consumption of the starting current is prevented.

When the lock attempt signal is received by the lock attempt detection unit 124 and the lock completion signal is received in the open / close detection unit 122 within the set time, the control terminal 200 transmits the lock completion signal The manager will be notified on-site with the message "Emergency door has been closed normally", and will be notified in real-time to the worker in the situation room through the wireless transceiver.

However, when the lock attempt signal is received by the lock attempt detection unit 124 and the lock completion signal is not received from the open / close detection unit 122 within the set time, the control terminal 200 notifies the on- Notifies the manager in real-time via the wireless transmission / reception unit 270, and notifies the status person in the status room through the wireless transmission / reception unit 270. In addition,

Therefore, according to the present invention, the situation recognition information including the open state of the emergency door, the abnormal closed state, and the normally closed state is accurately notified in real time to the manager located in the field and the situation employee located in the situation room, It is possible to prevent unnecessary consumption of the starting current as well as unnecessary driving of the restraint unit 120 when the emergency door is opened, especially when the field manager mistakes or confuses the lock state of the emergency door.

In the present invention, the force motor 125 is engaged with the forward / backward rod 124a constituting the lock attempt detection unit 124, so that the control terminal 200 can control the emergency door that enters the door frame F, 7, when the lock-up signal is received from the restraint unit 120 after the advance / retreat rod 124a is pressed by the fixed unit 110, and the lock-attempt signal is sensed, The motor 125 is instantaneously driven to provide a forward force to the retractable rod 124a which has retreated to verify the closing force of the emergency door by self-restraint.

In this embodiment, the rotary shaft of the forward / backward rod 124a and the force motor 125 is engaged with the rack and pinion structure, and the forward / backward rod 124a is advanced by the rotational force of the force motor 125.

7 to 8, the fixed unit 110 self-restrained by the restricting unit 120 is not pushed outward by the moving rod 124a advanced by the driving of the force motor 125, The control terminal 200 informs the manager located in the field of the notification that the electromagnetic force is good through the field notification unit 260. [

However, when the self-constraining fixed unit 110 is pushed outwardly by the moving rod 124a provided with the forward force from the force motor 125 and separated from the constraining unit 120, the constraining unit 120 is connected to the sensing circuit The control terminal 200 outputs an open signal to the control terminal 200 through the disconnection of the open / close detection unit 122. The control terminal 200 informs the user through the field notifying unit 260 that the electromagnetic force is insufficient To the on-site administrator.

That is, even if a starting current is supplied to the force motor 125 to provide a predetermined advancing force to the advancing and retracting rod 124a, the forces are not separated from each other by the self-binding force formed between the fixed unit 110 and the restraint unit 120 The control terminal 200 recognizes that the control terminal 200 has sufficient magnetic binding force.

However, when the control unit 200 receives an open signal from the fixed unit 110 and the restricting unit 120, the control terminal 200 determines that the self-limiting force of the lock control module 100 falls below the set value And notifies the administrator of the lock control module 100 of the abnormality via the field notification unit 260.

Accordingly, the manager located at the site senses an abnormality of the lock control module 100 and performs replacement or maintenance of the lock control module 100 to secure a stable magnetic binding force due to the lock of the emergency door.

In the preferred embodiment of the present invention, as shown in FIG. 3B, the detection switch member 124c is removed from the lock attempt detection unit 124, and the detection force of the engaging force motor 125 The control terminal 200 detects the emergency door lock attempt through the rotation.

That is, the force motor 125 is rotated by the advance / retreat rod 124a that retreats due to interference with the emergency door that enters the door frame F or the fixed unit 110 fixed to the emergency door, And the control terminal 200 detects the developed sensing current and converts it into a lock attempt signal.

With this configuration, the force motor 125 has a function of detecting a lock attempt to lock the emergency door and a function of pushing the magnetically confined fixed unit 110 outward to self-fix the self-binding force formed between the confining unit and the fixed unit Therefore, it is possible to minimize the restriction on the space due to disposing the detection switch member and the force motor separately, and to reduce the incidental cost.
