Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm system and method for an emergency ladder,

The present invention relates to an alarm system and method for a ladder of a top-down type escape lane, and more particularly, to an alarm system and method for a ladder for a top-down type escape ladder, The present invention relates to an alarm system and method for a top-down escape ladder, which protects persons from fire by allowing them to deploy and deploys a top-down ladder,

Generally, a high-rise building such as an apartment or a building is provided with an emergency escape apparatus for escaping the building in case of emergency, but an emergency escape apparatus for escaping the building in case the emergency escape hole can not be used.

An example of such an emergency escape device is an elevator that can move out of the building through a window.

However, since the elevator depends on the wire rope and descends along the outer wall of the building, there is a limitation that it is difficult and dangerous to use by the general public and the escape speed is considerably slow because many people can not escape at one time. It is not suitable for use.

On the other hand, when a fire occurs, flames and toxic gases are directed upward. Therefore, when a fire occurs in a high-rise building, it is desirable to evacuate to the lower side of the fire area.

To solve these problems, a high-rise building such as an apartment or a building with a large number of people is provided with a ladder for escape in a space such as a balcony or a veranda, thereby providing an evacuation route to the upper floor, I can evacuate.

The above-described escape ladder is classified into an escape ladder installed inside a building and an escape ladder installed outdoors. However, in recent years, the escape ladder is installed inside a building rather than an escape ladder installed outdoors to save the aesthetics of the building More escape ladders are being installed.

In the meantime, as shown in FIG. 1 and FIG. 2, the top-down type evacuation port is located in a space such as a balcony or a veranda such that the position of the ladder for the upper and lower stories is horizontally shifted. A first escarpment 2 in which a first ladder 4 descends to a current layer (for example, two layers) in a current layer (for example, two layers), and a lower layer (for example, And the second evacuation port 2 'where the second ladder 4' descending downward is located at a shifted position. The Ministry of Land, Transport and Maritime ordinance requires that the spacing be set at 15 cm or more apart, while the top- In the lower level, the upper level of the evacuation port can not be opened. The ladder has a length of 50 cm or less from the bottom surface of the lower level. If the lid is opened, And the lighting system should be installed by a backup power source in the place where the evacuation port is located. In addition, if the person concerned inspects the inspection result, the result of the inspection should be reported to the head of the fire department director or the fire department director have.

However, the shelter occupies a porch or balcony space, while the shelter does not know when it will be used, or it may not be used as long as it does not cause a fire. Therefore, depending on the household, However, in such a case, it is impossible to evacuate in case of emergency such as a fire, which can cause irreversible human casualties.

Particularly, in the upper part of the second evacuation port 2 'where the second ladder 4' descending from the current layer (for example, two layers) to the lower layer (for example, one layer) It is possible to evacuate the evacuation ladder and evacuate to the lower level after the evacuation ladder is opened (although in this case, the evacuation is also prevented even in this case, the present applicant's patent application (entitled " The first ladder 4 is located on the upper floor (for example, the third floor) to the current floor (for example, the second floor) (2), there is no big problem right now. However, there is a problem that the escape ladder can not be developed on the upstairs (for example, the third floor) in case of need, and measures should be taken accordingly.

On the other hand, the above-mentioned type of top-down type evacuation port is not required to open or open the upper level evacuation port in the lower level, and various countermeasures are provided. However, since the upper level should be able to open the evacuation port, And the like.

As a result, various measures have been taken in this regard, and the most common method is to transmit a signal to the fire receiver 300 only when a fire is detected in the fire detector 200, as in the utility model registration No. 0453544 The locking of the locking means 100 including the EM lock 110 and the latch 120 is electrically released to allow the top-down type evacuation port to be opened The emergency evacuation box automatic opening / closing device 120 (see FIG. 3 and FIG. 4) or only when the fire detection sensor 112 of the emergency emergence detection unit 110 detects a fire as in the case of the patent No. 1111292 (See FIGS. 5 and 6). In this way, the evacuation box 140 is automatically opened while the top-down escape ladder 150 is deployed.

However, according to these methods, the evacuation port can be opened only when the fire monitoring is successfully performed, which is preferable from the viewpoint of security. However, if the fire monitoring sensor is broken or the power supply is not properly supplied to the automatic opening / closing device, There is a further problem that the evacuation port is automatically opened unnecessarily even in a situation where the evacuation port can be evacuated even if a fire occurs.

On the other hand, according to Patent No. 1532051, as a third prior art, in an apartment in which a top-down type evacuation port and an evacuation exit door are installed for each furniture, a fire detection signal of an upper layer, Based on the outgoing or collective unlit control detection signal which can be used to check whether there is an evacuation floor furniture or not, it is possible to control the emergency evacuation to the lower floor residence space of the upper floor evacuee or the emergency evacuation to the lower floor, An apartment-top-down type evacuation-area interlocking evacuation system configured to enable an effective emergency evacuation while preventing the risk of infringement and crime damage, and a system for opening and closing the door opening and closing control system for the evacuation unit door opening and closing management system.

The third prior art will be described with reference to Figs. 7 to 10. Fig.

Referring to FIG. 7, a description will be given of a top-down type evacuation facility of the third prior art. In the third prior art evacuation facility, a descending ladder 4 is installed in the top- The spheres (2) are provided at positions staggered from each other so that their positions do not overlap each other.

Each of the top-down type evacuation ports 2 is provided with a downward-type evacuation port opening detector 7 described later. The top-down type evacuation opening detector 7 is configured to transmit such an open state to the control section 500 of the evacuation layer by an electrical signal when the upper layer (or pyrotechnic layer) . The top-down type evacuation port opening detector 7 may be constituted by, for example, a conventional limit switch, a contact switch or a magnetic type sensor, or may be a variety of known switches capable of detecting whether the cover is open or closed and transmitting the same through an electrical signal A sensor can be used.

The third prior art apartment-top-down type evacuation port interlocking evacuation exit door opening / closing management system has an evacuation exit door 9 capable of connecting or disconnecting the evacuation exits of the evacuation floor and the residential space. For example, when the emergency exits door 9 is in the shut-off state (door-closed state), it can be opened or closed by the electrical opening / closing means 8 that is opened or closed by an electrical control signal. The electrical opening / closing means 8 can be realized in the form of a conventional electromagnetic electric lock (electric lock) or a mechanical electric lock (for example, an electric motor driven latch type). The electrical opening / closing means 8 may be constructed in such a manner that opening is performed when power is applied, or vice versa, when the power is turned off.

For example, the electrical opening / closing means 8 applied to the exiting front door 9 of the third prior art is installed in the exit door of the evacuation room so that the electromagnet or the latch (not shown) And an electromagnet or a latch may be engaged / disengaged from the wall toward the exit door of the evacuation room. When this configuration is taken, there is an advantage that it is easier to connect and manage the power supply line and the signal input line for the latching / releasing operation of the electrical opening / closing means 8. Various commercial products have already been known as the electrical opening and closing means 8.

On the other hand, the electrical opening / closing means 8 of the exit and exit door 9 can be opened or closed by the operation of the opening switch 502, which will be described later, during the process of maintaining the normally closed state, Closure can be controlled.

Alternatively, the electrical opening / closing means 8 of the exit and exit door 9 is kept in the normally open state, and during the process of maintaining the normally open state, the execution of the second function, which will be described later, Type evacuation port 2 is detected, and whether or not the opening / closing of the top-down type evacuation port 2 is controlled by the operation of the opening switch 502 may be controlled.

The third prior art apartment-top-down type evacuation port interlocking evacuation exit door opening / closing management system has an opening switch 502 for opening and closing the electrical opening / closing means 8 of the exit / exit door 9.

The open switch 502 is connected to the central monitoring room server 300 or 320 connected to the home server 100 through an apartment signal line, .

The open switch 502 is implemented in such a manner that a specific UI button on the administrator screen of the server is operated using the administrator console of the central monitoring room server 300 or 320 It is possible. When the open switch 502 is provided in the central monitoring room server 300 or 320, the open switch is operated by the server manager so that the electrical opening / closing means 8 of the exit and exit door 9 can be opened Lt; / RTI >

Alternatively, the open switch 502 may be provided on the side of the evacuation front side in the case of one layer of the apartment, and on the side of the residential space and the evacuation side in the case of the other layers.

As a result of the execution of the sensing information providing function, the control unit controls the control unit 500 of the evacuation floor, the home server 100, and the central monitoring unit connected through the apartment signal line according to the execution of the first and second functions May be configured to provide an audible alarm to at least one of the real servers 300 or 320. Preferably, the alarm sound may be provided as a different alarm sound by distinguishing a case where a fire is generated as a result of the execution of the first function and a case where a fire signal is not detected.

In addition, a return switch for stopping the alarm sound may further be provided. For example, the return switch may be provided in the residential space or in the central monitoring room server 300 or 320 connected to the home server 100 through the apartment signal line.

The control unit 500 of the third prior art may be configured in the form of a control panel, for example, and may be installed on the evacuation-side or on the side opposite to the evacuation site (residence) or in a form accessible from both sides.

A fire indicator (fire evacuation or evacuation opening indicator), an emergency status indicator (an emergency invasion open status indicator), and the like are displayed on the panel of the control unit 500 installed on the side opposite to the evacuation side , An open switch (door open switch), a return switch, and the like. The opening switch (door opening switch) and the returning switch may be further provided with a normal display function.

A power indicator, a standby indicator (a waiting guide), a moving indicator (a moving guide), an open switch (door opening switch), and the like may be provided on the panel of the control unit 500 installed on the evacuation destination side. The opening switch (door opening switch) may be further provided with a normal display function. The open switch on the evacuation side is opened by usual operation when it is normally detected (the upper level of the upper level escape hole is not open), and the emergency situation (the upper level of the upper level escape hole is detected as open ), The switch opening operation on the evacuation side can not be performed, but can be set to be operated only by a separate openable setting by the apartment manager or the floor occupant of the floor. However, in the case of fire in the above case (when a fire occurs in a floor of two or more floors, and a two-level downhole is detected as open), the open switch on the side of the first floor So that it can be opened.

The panel of each control unit 500 may further include an alarm sound generating unit. The alarm sound may be provided by distinguishing the case where the fire is generated in the upper level as a result of the execution of the first function and the case where the fire signal is not detected.

The system of the third prior art apartment-down-type evacuation interlocking evacuation exit door opening / closing management system comprises a first function for detecting an upper level fire signal through a fire alarm repeater 210 and a second function for detecting an upper level fire signal through a top- Based on the detection result of each function according to the execution of the third function for detecting the outgoing signal of the evacuation floor through the home server 100, a second function for detecting an open signal of the upper-level evacuation port 2, And a control unit (500) for executing at least the detection information providing function for providing the detection result to at least one of the residence space or the evacuation facility. For example, the control unit 500 may be implemented in the form of a conventional embedded system, and may include a known input unit and an output unit for inputting a control set value and displaying a control status.

The control unit 500 of one layer and another control unit 500 of a layer other than the layer may be interlayer interlocked through the home server 100 provided for each household and the home network server 300 connected to the home server 100 have.

8 to 10, the control unit 500 installed for each household is connected to the home server 100 of the corresponding furniture, and the control unit 500 is connected to the home It is possible to detect whether or not it is in a state of going out. For example, various sensors and switches for providing various home network services are connected to a normal home server 100. In the case of the third conventional technology, the home server 100 through the operation of the collective control switch 110, The home server 100 receives the outgoing signal of the evacuation floor through the outgoing signal input of the home server 100 or the like and detects whether the furniture (evacuation floor) is in the outgoing state. If it is not in a batch-off or outing state, it can be viewed in the same state as the home.

Through the above-described configuration, the outgoing signal detection of the evacuation floor through the home server 100 at the time of executing the function can be performed by detecting any one of inputting the outgoing state through the home server 100 or inputting the batch unlit signal .

The control unit 500 receives a signal from the fire alarm monitoring server 320 or the home network server 300 of the central monitoring room (disaster prevention room) connected to the home server 100 through the apartment signal line, The occurrence state can be detected. The fire alarm repeater 210 is provided for each floor so that when a fire is detected by the fire detector 200 for each household of a specific household on the floor, the fire alarm repeater 210 transmits the fire alarm alarm to the fire alarm surveillance server 320 located in the apartment central monitoring room (disaster prevention room) Or to the home network server 300. [ The apartment signal line may include a normal data backbone server 140, a new communication room 130, a household terminal box 120, and the like.

The opening detection signal of the top-down type evacuation port opening sensor 7 installed between the upper floor and the evacuation floor includes, for example, a top-down type evacuation opening detector 7 between the upper floor and the evacuation floor, -> the evacuation layer control unit 500 '. In this case, the home server 100 of the evacuation floor transmits an open sensing electrical signal to the evacuation gate opening / closing monitoring server 310 or the home network server 300 of the central monitoring room (disaster prevention room) The home server 100 of FIG.

Alternatively, the opening detection signal of the top-down type evacuation port opening sensor 7 installed between the upper floor and the evacuation floor can be transmitted to the home server 100 of the upper floor, The home server 100 of the evacuation floor, and the control unit 500 of the evacuation floor in the room (disaster prevention room).

FIG. 9 is a control flowchart of a system for opening and closing the door of the apartment-type top-down type evacuation system interlocking evacuation door according to the third prior art.

In step S10, the controller 500 detects an upper level fire signal through the fire alarm repeater (step S12). In step S12, the controller 500 detects an open signal of an upper-level refuge (The second function). In step S14, the control unit 500 detects the outgoing signal of the evacuation floor through the home server (third function).

Then, based on the detection results of the respective functions, a detection information providing function is provided to provide the detection result to at least one of the residence space or the evacuation facility.

In the case of providing the detection result to the residential space side, the resident of the evacuation floor in the residential space confirms whether the actual fire in the upper level and the actual escape of the upper-floor resident are evacuated based on the detection results of the first and second functions, The opening switch 502 is opened to open the electrical opening / closing means 8 of the exit and exit door 9 so that the evacuator can be rescued. This process corresponds to S50 to S60 in Fig.

In detail, in step S20, the controller 500 senses an upper level fire occurrence state as a result of execution of the first function, and in step S22, the controller 500 determines whether the upper- The control unit 500 senses that the evacuation layer 2 is in the open state and the control unit 500 detects that the evacuation layer is out or in the home state as a result of the execution of the third function in step S24. As a result of executing the information providing function, the detection result of each function according to the execution of the first and second functions is provided to the living space side.

When the result of the detection is provided to the evacuation destination side, a resident of the upper floor evacuating to the evacuation destination of the evacuation floor may determine that the resident of the evacuation floor can open the open switch 502 based on the detection result of the third function And whether or not they should evacuate further downstairs. This process corresponds to S40 in Fig.

In detail, in step S20, the controller 500 senses an upper level fire occurrence state as a result of execution of the first function, and in step S22, the controller 500 determines whether the upper- The control unit 500 senses the open state of the bulb 2 and if the control unit 500 detects that the evacuation layer is out or in the home state as a result of the execution of the third function in step S24, As a result of executing the information providing function, provides the detection result according to the execution of the third function to the evacuation location side. As a preferable example, it is possible to provide an alarm sound to at least one of the control unit of the evacuation floor, the home server, and the central monitoring room server connected through the apartment signal line, together with the provision of the detection result. It is further preferable that the alarm sound is provided in a different sound by distinguishing a case where a fire is generated in an upper level as a result of execution of the first function and a case where a fire signal is not detected.

For example, in the control process, a moving indicator lamp (a moving indicator) is operated in the panel of the controller 500 installed on the side of the evacuation area of the layer detected as being out of the room. Accordingly, the evacuator can quickly evacuate without being disturbed through the door (9) of the evacuation room of the lower-level residential house without staying in the evacuation floor furniture going out, and the out- The electric opening and closing means 8 is in a closed state, so that it is possible to prevent invasion of privacy.

FIG. 10 is another control flow chart of the system for opening and closing the door of the apartment top-down type evacuation tunnel interlocking evacuation door according to the third prior art.

In step S110, the controller 500 detects a fire signal in an upper layer through a fire alarm relay (first function). In step S112, the controller 500 detects an open signal of an upper-level refuge In operation S114, the control unit 500 detects whether the electrical opening / closing unit 8 provided in the upper exit door 9 is opened or closed (a fourth function). For example, when the electrical opening / closing means 8 is opened or closed through the control unit 500, the control unit 500 can directly detect the opening / closing state of the electrical opening / closing means 8, As another example, when the opening / closing of the electrical opening / closing means 8 is directly received by the operation of the opening switch 502 without passing through the control unit 500, the opening / The control unit 500 can detect the open or closed state of the electrical opening / closing unit 8. The sensing means may be any known electronic sensing means of a type similar to a top-down type evacuation opening sensor. Thereafter, the detection information providing function (or alarm sound providing function) is executed based on the detection result of each function.

In detail, if the control unit 500 determines in step S120 that the fire is not generated in the upper layer as a result of execution of the first function, the controller 500 determines in step S122 that the fire In step S124, the control unit 500 senses that the electrical opening / closing unit provided in the upper door of the evacuation unit door is open in the upper level as a result of the execution of the fourth function. In step S126, The control unit 500 detects an upper level fire occurrence state according to the execution result of the first function within a predetermined set time (for example, five minutes) after the electrical opening / closing means provided at the entrance / The control unit 500 of the evacuation floor, the home server 100, and the central monitoring room server 300 or 320 connected through the apartment signal line, as the execution result of the detection information providing function, And is configured to operate an alarm sound on any one of them.

The reason for taking the above-mentioned configuration is that even if a fire is generated on the upper floor and the occupant of the upper floor escapes from the fire to the upper floor evacuation excavation, the user is unable to open the lower ceiling evacuation port 2 Lost state) has occurred, so that the user can give assistance from the outside.

That is, in the case of the third prior art, an evacuation room capable of being automatically opened and closed is separately installed in each floor, and is interlocked with a fire detector of each floor, and when a fire is detected, If the residents of the lower floors are at home, they will be informed to evacuate to the outside of the building. If they are out, they will evacuate further down the hall. On the other hand, If the opening / closing means is not opened to the outside, notification is made to the outside to request the structure.

However, in the case of the third prior art, since it is still required to be interlocked with the fire alarm, the problem caused by the failure or malfunction of the fire alarm remains as in the first and second prior arts, It is premised on the construction of expensive devices and systems such as the opening / closing device of the excavation and the home automation, and the fact that the facilities which may be used once in a lifetime, It is true that both the state and the contractor are burdened.

For the most part, I hope that the above facilities will be resolved at several hundred thousand won per household. Nevertheless, it is more realistic to be able to rescue people without a problem in the event of a fire, and at the same time clean up security problems.

At this time, the sensor unit 200 is installed at the lower end of the evacuation port 2 to detect the position of the lower layer to which the evacuation ladder 4 is to be deployed, A near-field sensor 210 for detecting whether or not an object (for example, 50 cm or more) is loaded, and an evacuation opening sensor 220 for sensing whether the evacuation port is opened.

The near-field sensor 210 may be a photosensitive line sensor which is installed at a position of the evacuation port of the lower layer and is spaced apart from a control unit which applies a sensing signal to the control unit 100 by wire or wire, The light receiving unit may be a photosensitive line sensor directly connected to the control unit 100, but preferably both the light emitting unit and the light receiving unit are attached to the lower side of the refuge of the present layer, The sensor may be directly connected to the controller 100, and the sensor may be an RF electromagnetic wave as well as an infrared laser or an LED light.

The evacuation opening detection sensor 220 may be a conventional sensor such as a photo sensor as well as a magnet sensor installed on a cover of an evacuation port.

The warning unit 400 may be a warning light unit, a siren unit, or a loudspeaker unit for outputting audio information that is recorded on the base. Preferably, the warning unit 400 includes a lower warning unit 410 for warning the lower layer, It is preferable that the current layer warning unit 420 is separately operated.

Now, a control method of the control unit 100 of the alarm system of the ladder of the top-down type evacuation will be described in detail with reference to Fig.

First, the controller 100 issues a sensor driving signal at a predetermined time interval (for example, 30 minutes) to the near-field sensor 210, and loads the object at the deployment position of the ladder of the top- This is to detect the possibility of hindering the development of the dragon ladder.

At this time, if the detection is performed at an excessively long time interval, there is a high possibility that the time interval from the obstruction of the evacuation ladder deployment to the detection becomes long, and there is a possibility of occurrence of an emergency situation therebetween. In contrast, when sensing is performed too frequently, there is a possibility of causing a problem due to the discharge of the battery when the battery is used because the commercial power is not supplied due to various reasons. .

Meanwhile, the near-field sensor 210 performs near-field sensing in response to a sensor driving signal transmitted from the control unit 10 at a predetermined time interval (for example, 30 minutes) at a predetermined time T1. If the elevated ladder is loaded with too high an object (for example, at a height of 50 cm or more), the evacuation ladder may not be smoothly deployed in case of emergency, and most preferably, It is recommended to prevent the loader from being stowed. However, if a warning is given to a very small object, it may also cause discoloration between upper and lower floors due to frequent alarms. Therefore, Is prohibited.

Accordingly, it is determined whether or not the load of a predetermined height or more is detected, that is, whether or not the near sensor signal is received (S11). If the near sensor signal is not received in the above step, (S12), a sensor driving signal is issued again to repeat the near-field sensing operation.

On the other hand, if the near sensor signal is received in step S13, it is determined whether or not the evacuation port opening signal is detected through the evacuation opening detection sensor 220 (S13) Because an emergency situation such as an earthquake or a robbery occurs and a resident of the stratum can not evacuate to the entrance so that the evacuation ladder is opened due to the opening of the evacuation zone directly and the near sensor can detect it.

In the case of the opening of the evacuation port, a thief who has entered the entrance or window of the floor may open the evacuation port and evolve the evacuation ladder by exploiting the top-down type evacuation port, which may occur outside the emergency situation .

Accordingly, when the emergency exit opening signal is detected in step S13, a first alarm sound indicating that the evacuation port is opened is generated, and a notification is made to the management room and the security room (more preferably, also to the fire station and the police station) In case of fire, fire extinguishment should be done. If there is a thief, 112 should be informed and crime prevention should be done.

In addition, preferably, the first alarm sound is issued to both the lower-layer warning unit 410 and the current floor warning unit 420. In any case, the first alarm sound is an actual emergency situation, If necessary, a warning light is also mobilized so that it can be transplanted from the outside.

Alternatively, the step S14 may be performed in conjunction with an existing fire detector. In this case, if the fire detector detects a fire, it is sent to the management room and the fire department, and if it is not fire detection, So that it can be biased.

 If the evacuation opening signal is not detected in step S13, the sensing is performed again after waiting for the second time interval T2 (S15). The reason for performing the sensing again is that, for example, The second time interval T2 may be equal to or different from the first time interval T1. In this case, the second time interval T2 may be equal to or different from the first time interval T1. In general, a moving person or an object can not be stopped continuously for 10 minutes or longer. The second time interval T2 is preferably about 10 minutes.

Thereafter, it is determined whether there is near-field sensing (S16). If it is determined in step S16 that there is no near-field sensing, it is regarded as a moving object or object and the first return is made. , It is regarded that the object is placed on the lower layer, and a second alarm sound is generated in a primary (S17).

At this time, the second alarm sound is not an emergency situation and may be of a degree of caution, so it may be a weak alarm sound rather than the first alarm sound, or an electronic voice of degree of "please obstruct an obstacle of an evacuation hole" . In addition, it is preferable to send an alarm only to the lower-layer warning unit 410.

Thereafter, after the waiting time T3 again, the re-sensing is performed (S18), the alarm in the step S17 is heard, the case where the occupant of the lower floor clears the obstacle is assumed, Re-sensing is performed.

If it is determined in step S19 that there is no proximity sensing, it is determined that the obstacle has been removed (S20), and if there is proximity sensing still after T3, , It is regarded that the obstacle is not removed from the lower layer, and the notification to the management room is performed secondarily (S21).

Thus, in the management room, the manager directly directs the residents to take down the obstacles in the status of the co-housing manager from the lower-level households, or to take other necessary enforcement measures (such as direct visits to collect obstacles) Of the total number of employees.

In addition, the system of the present invention can be implemented in conjunction with home automation or IoT (object Internet) adopted in a high-class apartment complex such as a recent apartment complex. In this case, the control unit 100 controls the home server And the warning unit 400 can be replaced with an alarm unit connected to the home server of each floor and a management server or a guard room can be replaced with a management server of the apartment house. It will be possible without exerting the creative ability of.
