Such a remote fire station terminal is connected to the emergency power source 20 of the disaster prevention room and the wire is supplied with power in the present specification and claims, such wire is defined as "fire line 30".

The management means 200 is installed to be electrically connected to the emergency power supply 20, more specifically to the fire line 30 in the area where the manager resides, such as the disaster prevention room.

The automatic opening and closing means 100, the first central control unit 110 for controlling each part and outputs an emergency door opening and closing control signal in accordance with the emergency control signal received from the management means 200, fire line 30 and A first filter / combining unit 120 that separates or couples a power supply and a data signal from the connected power line signal, and a first communication module unit that receives a data signal transmitted from the filter / compositing unit 120 130 and the switch controller 140 which receives the emergency door open / close control signal from the first central controller 110 and outputs an emergency door operation signal.

Reference numeral 150 denotes a first battery for continuously applying current to the automatic opening and closing means 100 even in a power failure, and reference numeral 160 denotes a first manual control unit provided to manually open an emergency door. In addition, reference numeral 40 denotes an emergency door operating means for receiving the emergency door operation signal from the switch control unit 140 to operate the emergency door to open, and reference numeral 50 is a monitoring means for monitoring the opening and closing state of the emergency door.

The management means 200 transmits a data signal output from the second central control unit 210 and the second central control unit 210 for controlling each unit, receiving a detection signal and outputting an emergency control signal therefrom. The second communication module 220, a signal receiving unit 230 for receiving a signal transmitted as an emergency situation such as a fire by the automatic detection means 60, and the second communication module 220 And a second filter / combining unit 240 for coupling the data signal output from the power line with the frequency of the power line to synthesize the power line signal.

In addition, the management means 200 is a panel unit that can be provided with a warning light (not shown) that visually shows the occurrence of an emergency situation or the opening and closing state of the emergency door, or a speaker (not shown) that generates an audio alarm ( 250).

In addition, reference numeral 260 denotes a second battery capable of continuously supplying current to the management means 200 even during a power failure, and reference numeral 270 denotes a second manual operation unit for manually operating the emergency door.

In addition, the automatic detection means 60 includes any kind of sensor means known to detect a fire or smoke, including a fire detector.

Then, the operation of the emergency door automatic opening and closing system according to the present invention configured as described above will be described in detail with reference to FIG.

First, the second central control unit 210 of the management means 200 continuously determines whether a detection signal for informing a fire or the like is received (step S300). The detection signal is generated by the automatic detection means 60 detecting fire or smoke. That is, when a fire occurs, the automatic detection means 60 outputs a fire detection signal, which is received by the signal receiver 230 and then transmitted to the second central controller 210.

Then, if it is determined that the detection signal has been received, the second central control unit 210 outputs an emergency control signal to operate the emergency door (step S310). Preferably, the second central control unit 210 may transmit a separate output signal to the panel unit 250 to blink a warning light or generate an alarm through a speaker.

The output emergency control signal is transmitted along the fire line 30 in step S320. Specifically, the data signal output from the second central control unit 210 passes through the second communication module unit 220 to the second filter / synthesizing unit. And a second filter / synthesizer 240 couples the data signal to a power line frequency for Power Line Communication (PLC). As is known, power line communication is the transmission and reception of data at a frequency (1-30 MHz) that is much higher than the width (about 60 Hz) needed to send and receive power among the frequency widths within the power line. In general, power line communication is very vulnerable to noise and a lot of data loss, but according to the present invention, the fire line is embedded in the wall of the building to shield the influence of electric appliances such as air conditioning or audio through which strong electricity flows, It is relatively short-range and can be used effectively without any noise or data loss. The synthesized power line signal is transmitted along the fire line 30 to the automatic opening and closing means 100 electrically connected to a remote fire line terminal such as an induction lamp 10.

The first central control unit 110 determines whether an emergency control signal is received (step S330), and if a signal is received, outputs an opening / closing control signal to open the emergency door and transmits it to the switch control unit 140 (step S340).

The switch controller 140 determines whether an open / close control signal is received from the first central controller 110 (step S350), and if so, outputs an emergency door operation signal to open the emergency door (step S360).

The emergency door operation signal is transmitted to the emergency door operation means 40, and then the emergency door is opened by the operation of the operation means 40 (step S370).

According to the present invention, the opening and closing state of the emergency door can be continuously monitored to notify the manager of the disaster prevention room where the management means 200 is located. In detail, the opening / closing state of the emergency door is sensed by the monitor means 50, and the generated monitor signal is transmitted to the switch controller 140.

In response to the received monitor signal, the switch controller 140 notifies the first central controller 110 of the abnormality that the emergency door is abnormally opened, and accordingly, the first central controller 110 is abnormal. Output the signal.

The abnormal signal data output is converted into a data packet by the first communication module unit 130 and then coupled to the power line frequency by the first filter / combining unit 120. Next, the synthesized power line signal is transmitted to the management means 200 along the fire line 30 that connects the remote fire line terminal 10 and the emergency power source 20, the second filter / synthesis unit 240 The data signal is separated out. The separated data signal is transmitted to the second central control unit 210 via the second communication module unit 220 again, and the second central control unit outputs a warning signal to the panel unit 250, for example, the panel unit 250. By flashing a warning light or triggering an alarm through the speaker, you can alert the administrator of an abnormal condition of the emergency door.

According to the invention, the emergency door can also be opened by manual operation. Manual opening of the emergency door may be performed using the management means 200 in the remote disaster prevention room or in the automatic opening and closing means 100 located near the emergency door.

First, when the manager located on the management means 200 side operates the manual operation unit 270, the second central control unit 210 outputs the emergency door manual opening signal according to the signal. As described above, the output signal is synthesized with the power line through the second communication module unit 220, the second filter / combining unit 240, and then transmitted to the automatic switching unit 100 through the fire line 30. do.

Subsequently, the data signal separated by the first filter / combining unit 120 of the automatic switching unit 100 is received by the first central control unit 110 via the first communication module unit 130 and the first central control unit ( 110 is to command the opening of the emergency door by outputting the emergency door opening and closing control signal as described above.

On the other hand, when the emergency door opening operation using the first manual control unit 160 located on the automatic opening and closing means 100 side, the first central control unit 110 transmits the opening and closing control signal to the switch control unit 140 to open the emergency door. Simultaneously with the opening, the emergency door opening state signal is transmitted to the management means 200 through the first communication module 130. The open state signal is synthesized into a power line signal in the manner described above and transmitted to the management means 200 along the fire line 30, and the transmitted power line signal is processed by the second filter / combining unit 240 therefrom. The data signal is separated. The separated data signal is received by the second central control unit 210, from which a status display signal is output to the panel unit 250. Accordingly, the panel 250 may allow the administrator to visually confirm the opening of the emergency door by, for example, turning on the emergency door opening lamp according to the status display signal.

Emergency door automatic opening and closing system according to the present invention is provided with the first and second batteries 150, 260 by itself, even if the emergency power source 20 is cut off due to an accident such as a power failure, the fire line 30 by the battery power source ) Can be used for communication.
