Referring to the drawing, for the power line 12 to which the main power source AC 220V is applied, the power conversion unit 30 for generating the DC power required for the corresponding emergency door automatic switching device 10 is connected, and the power source. The power supply state detection unit 32 that detects whether or not the output of the DC power from the converter 30 detects a state including a power failure of the main power supply is connected.

In addition, the fire signal line 14 is connected to a fire signal detection unit 34 for detecting whether a fire signal is applied from the fire signal receiver through the fire signal line 14.

The battery 36 which applies the emergency power in the power failure state of the main power is charged through a battery charging means (not shown), and whether the battery 36 is in a circuit fault state or abnormally charged is the battery state detection unit. Is detected by 38.

The main power detection result of the power state detection unit 32, the fire signal detection result of the fire signal detection unit 34 and the battery state detection result are applied to the control unit 40, and the input side of the control unit 40 is The 10-key portion 18 and the emergency switch 22 are also connected.

An operation state display unit 16 for driving the LED elements 16a to 16f is connected to an output side of the control unit 40 and an emergency door driver 42 for opening an emergency door. And emergency door opening and closing 44 and the alarm unit 20 is connected.

Here, the emergency door opening and closing door 44 is preferably assumed to be an electromagnetic lock (Electromagnetic lock), it is also possible to apply the door opening and closing structure employed in the digital door lock including an electric motor or a solenoid.

Referring to the normal operation of the emergency door automatic opening and closing device 10 of the above-described configuration, first, the password input by the operation of the 10-key unit 18 is stored in the internal memory area or under the control of the control unit 40; It is stored in a separate memory area (not shown).

In this state, the main power applied to the corresponding emergency door automatic opening and closing device 10 through the power line 12 is converted into DC power through the power conversion unit 30 to the corresponding emergency door automatic opening and closing device 10 In addition to being applied as an operating power source of), it is also applied to the charging of the battery 36.

When the DC power is normally applied from the power conversion unit 30 through the power state detection unit 32, the control unit 40 may display the main power state display LED device 16a through the operation state display unit 16. While the normal state of the main power supply is turned on visually, when the DC power is not output from the power conversion unit 30 or is output at an abnormal level, the main power state through the operation state display unit 16. The display LED device 16a is turned off or blinks to visually check an abnormal state of the main power supply.

In addition, when the battery 36 is normally connected through the battery state detecting unit 38 and a normal charging power level is detected and applied, the control unit 40 provides emergency power through the operating state display unit 16. In addition to turning on the status display LED element 16b, the charging state of the battery 36 controls the lighting state of the emergency power charging state display LED element 16c, while the battery 36 controls the circuit. In the case of a short-circuit state or normal charging does not proceed, it is detected as a battery failure and the emergency power state display LED element 16b and the emergency power state display LED element 16c through the operation state display unit 16. Will turn off or flash.

In the state where the main power received through the power line 12 and the battery 36 are in a normal state, the control unit 40 locks the emergency door through the emergency door driving unit 42 through the emergency door driving unit 42. To be maintained.

In that state, when a fire signal (that is, a signal applied to a fire alarm or emergency exit induction from the fire signal receiver) is applied from the fire signal receiver to the fire signal line 14 through the fire signal line 14, the fire signal is set to the fire signal. The control unit 40 is provided to the control unit 40 through a signal detecting unit 34, and accordingly, the control unit 40 operates the emergency door opening / closing door 44 through the emergency door driving unit 42 to lock the emergency door. This will allow them to be released so that emergency doors can be opened and evacuated quickly in the event of an emergency.

In addition, the control unit 40 causes the emergency door opening / closing state display LED element 16f to be turned on or flashing through the operation state display unit 16, and outputs an alarm sound through the alarm unit 20. do.

Preferably, the control unit 40 is operated by the emergency power (preferably the power supply duration is 20min or more) provided from the battery 36 within a predetermined time (for example, 5sec) when the main power is determined to be abnormal. While controlling the control to switch to, when the abnormal state of the main power has passed a predetermined time (for example 20 minutes) through the emergency door driving unit 42 to operate the emergency door opening and closing 44 to lock the emergency door Is controlled to switch the current display state of the main power state display LED element 16a and the emergency door opening / closing state display LED element 16f through the operation state display unit 16 so as to be displayed.

In this case, in the case of the emergency switch 22 connected to the input side of the control unit 40, the control unit 40 immediately opens the emergency door opening and closing door 44 through the emergency door driving unit 42 in response to the operation. Since the emergency door is opened by the operation of the emergency switch 22, the emergency door is opened in a very normal state in which the main power and the emergency power are normal and no fire signal is applied from the fire signal receiver. Will be disadvantageous.

In view of this, in the first embodiment of the present invention, the emergency door can be opened by the emergency switch 22 when any one or two or more states of the main power source, the emergency power source, and the fire signal occur. The arbitrary opening to the bar will be prevented, which will be described in detail with reference to the flowchart shown in FIG. 3.

The control unit 40 determines that the emergency switch 22 is operated in the state in which the emergency door opening and closing door 44 is kept in the closed state (step 50), if it is determined that the emergency switch 22 is operated (YES in step 52). It is determined whether a fire signal which mediates the fire signal line 14 is detected by the fire signal detecting unit 34 (step 54).

As a result of the determination, when the fire signal is detected in the fire signal detecting unit 34 (YES in step 54), the control unit 40 proceeds to step 56 and the emergency door driving unit 42 passes through the emergency door driving unit 42. By controlling the emergency door to be opened by driving the emergency door opening and closing 44, the alarm unit 20 is operated to output an alarm sound (step 56).

If the fire signal is not detected as a result of the determination in step 54, the process proceeds to step 58 and when the converted DC level of the main power applied by the power conversion unit 30 is determined to be abnormal through the power state detection unit 32. (YES in step 54), the process proceeds to the above step 56 to drive the emergency door opening and closing 44 through the emergency door driver 42 to control the emergency door to open and to operate the alarm unit 20. Alarm sound is outputted.

In addition, when the main power is determined to be normal in the determination in step 58, when the main power is determined to be normal and the battery 36 is judged to be in an abnormal state through the battery state detecting unit 38 (YES in step 60), the The control unit 40 moves to the above step 56 to drive the emergency door opening and closing door 44 through the emergency door driving unit 42 to control the emergency door to be opened, and to operate the alarm unit 20 to alarm. The sound will be output.

Here, the control unit 40 is visually displayed by the LED display device via the operation state display unit 16 even during emergency door opening control by detecting abnormality of emergency power by the main power and battery and detection of fire signal. Will also be made.

Therefore, in the first embodiment of the present invention, the control unit 40 responds to the operation of the emergency switch 22 only in response to any one or two or more of abnormal detection of the main power supply and emergency power of the battery and detection of a fire signal. The door is controlled to be opened, thereby preventing any access by the unauthorized operation of the emergency switch 22.

In addition, according to the first embodiment of the present invention, a function of turning on / off by the 10-key unit 18 may be added with respect to whether the emergency switch 22 can be operated.

That is, when a changeable password (eg, 1111) assigned to turn off the function of the emergency switch 22 is input by the 10-key portion 18, the controller 40 functions as the emergency switch 22. While the password is re-entered or a changeable password (e.g., 4321) assigned to the emergency switch 22 to turn on the function is input, the control unit 40 returns to the emergency switch 22 function. It may be ON.

Here, when any one of abnormality and fire signal of the emergency power by the main power and the battery shown in FIG. 3 is detected by the 10-key unit 18 even when the function of the emergency switch 22 is turned off, It is more preferable if the operation by the emergency switch 22 is turned on immediately.

4 is a view illustrating a schematic configuration of an emergency door automatic opening and closing device to which a second embodiment of the present invention is applied, and FIG. 5 is a functional block diagram of the automatic emergency opening and closing device shown in FIG. 2. Parts corresponding to the configurations shown in Figs. 1 and 2 for one embodiment will be described with the same reference numerals.

The emergency door automatic opening and closing device 10 to which the first embodiment is applied is configured to operate in response to a fire signal of the fire signal receiver (that is, a signal applied to drive an alarm or an emergency induction in the event of an emergency). In such a configuration, the second embodiment of the present invention takes into consideration that the emergency door automatic opening and closing device 10 also malfunctions when the fire signal receiver and / or the alarm or the emergency exit guidance are not normally operated due to, for example, a neglect of management. In the embodiment, the emergency door automatic opening and closing device 10 is characterized in that the fire detection sensor 60 is provided.

According to the second embodiment of the present invention, in the case of a high-rise stepped building, for example, when a fire occurs in the lower floor, the smoke sensor 62 is preferably applied to the smoke detection sensor in consideration of the fact that the smoke quickly spreads to the upper floor. However, as the fire detection sensor 62, of course, the application of a heat detection sensor or a flame (flame) detection sensor is also possible.

Therefore, a smoke detection sensor is integrally installed as the fire detection sensor 60 on the front surface of the automatic emergency door opening and closing device 10 shown in FIG. 4, and the fire detection sensor 62 is the control unit 40 in FIG. 5. It is configured to be linked to.

In such a configuration, when a fire signal is detected from the fire signal detector through the fire detection line 14 or a fire is detected from the fire detection sensor 62, the controller 40 controls the emergency door driver 42. Through the emergency door opening and closing 44 is to be released immediately.

Here, the emergency switch 22 may be operated only at the time of detecting the abnormality and the fire signal of the emergency power by the main power and the battery described with reference to FIG. 3 and the fire detection by the fire detection sensor 62.

6 is a view for explaining a schematic configuration of an emergency door automatic opening and closing device according to a modification of the second embodiment of the present invention.

In the emergency door automatic opening and closing device 10 according to a modification of the second embodiment, instead of the fire detection sensor 62 shown in FIG. 4 or additionally, the fire detection sensor 64 (preferably a smoke detection sensor) is wired. Represents a connected structure.

In that case, the fire detection sensor 64 is installed at a position where smoke detection is easier (for example, a ceiling surface or a lower floor above the stairs), thereby enabling a faster smoke detection.

FIG. 7 is a view for explaining a schematic configuration of an emergency door automatic switching device according to another modification of the second embodiment of the present invention, and FIG. 8 is a functional block diagram of the emergency door automatic switching device shown in FIG.

That is, according to another modified example of the second embodiment of the present invention shown in FIG. 7, a wireless fire detection sensor 66 (preferably a smoke detection sensor) is linked to the emergency door opening and closing device 10. The exterior of the automatic door opening and closing device 10 is provided with a wireless fire detection signal receiving window 68 for receiving a wireless fire detection signal transmitted from the wireless fire detection sensor 66, the wireless fire detection signal receiving window 68 Is configured to be connected to the control unit 40.

In that case, the wireless fire detection sensor 66 may be installed in a position where the fire detection is more flexible than the configuration shown in FIG. 6, and the application of a heat detection sensor or a flame detection sensor may be possible.

In addition, even in the configuration shown in Figures 7 and 8, the fire detection sensor 62 shown in Figure 4 may be provided as a whole.

In addition, the emergency switch 22 may be operated only at the time of detecting the abnormal and fire signals of the emergency power by the main power and the battery described with reference to FIG. 3 and the fire detection by the wireless fire detection sensor 66. .

Meanwhile, the present invention is not limited to the above-described embodiments, and various changes and modifications can be made without departing from the technical gist and gist of the invention.

For example, in the above-described embodiment, the application of the password by the 10-key unit 18 is assumed to turn ON / OFF the function of the emergency switch 22, but the magnetic key or the semiconductor key is applied to the emergency door automatic switching device.
