Description

Disaster evacuation guidance system using gobo lighting

The present invention relates to temporary firefighting facilities and disaster guidance and prevention of human casualties, and more specifically, information according to changes in the environment is intuitively displayed using gobo lighting in large buildings, multi-use facilities, and construction sites under construction. It relates to a disaster evacuation guidance system that can be seen and prevent human casualties.

In general, when a fire occurs in a multi-use facility or high-rise building, facility users or residents move according to the evacuation guidance system to evacuate from flames and toxic gases and use the ladder of a firefighting vehicle at a predetermined location, or use the emergency equipment installed separately in the building. An evacuation system using an evacuation device for evacuation is being applied. The evacuation guidance system currently used in general is implemented according to the regulations specified in the Building Act and Fire Safety Management Standards, and various contradictions are being improved and applied by foreign advanced systems such as the National Fire Protection Association (NFPA).

The evacuation guidance system is limited to the level of emergency exit guidance display and lighting, and there is no significant improvement from the past. That is, there is some improvement in terms of extending the lighting time or securing illumination in case of a fire, and a lighting system capable of displaying an evacuation route in order to overcome the problem that the evacuation route cannot be properly recognized due to poor visibility due to smoke generation during a fire There are some attempts to improve. However, it can be seen that the above technologies are merely indications or lighting equipment rather than the function of evacuation itself.

The occurrence of a fire is usually more damaging due to toxic gas than direct injury from flames, because the toxic gas fills the inside of the building within a relatively short time, so there is not enough time to wait for help from the outside. It is especially important to evacuate quickly in multi-use facilities such as high-rise buildings and large shopping malls.

However, the current fire evacuation guidance lights do not have a guiding function for the actual evacuation route, and are close to the function of the so-called emergency lighting that displays a simple emergency exit or passage at a designated location. It is difficult to say that conventional evacuation guidance systems are made to be easily recognized and understood in a state where the field of vision is unclear and psychologically unstable. Moreover, there is a limitation in that it is difficult to properly respond according to the situation of the fire site that changes every moment.

On the other hand, in a construction site in which the building is not completed, the above-described risk further increases when a fire occurs because firefighting facilities are not complete. If combustible materials are loaded among the construction materials loaded at the construction site, the risk increases rapidly.

In consideration of this risk, the installation of temporary firefighting facilities is mandatory in construction sites with fire risks according to the Fire Prevention and Firefighting Facility Installation Maintenance and Safety Management Act in Korea. In the construction of a specific fire-fighting object, it is required to install, maintain, and manage a fire-preparation facility that is easy to install and dismantle before performing fire-dangerous work in construction for construction, major repair, change of use, or installation, etc. . These temporary firefighting facilities include simple firefighting facilities and emergency alarm facilities.

Korean Patent Application Laid-Open No. 10-2017-0081371 discloses a technology for easy movement and installation of a prior art temporary fire fighting device, and FIG. 1 is a perspective view thereof.

Schematically, the mobile cart 100 includes an emergency kit box 20, a fire extinguishing device 30 including a fire extinguisher, and a wireless breaking device 40 mounted on the mobile cart 100 to be exposed to the outside. mounted. The mobile cart 100 is disposed in a work area for handling fire where there is a risk of fire, and is provided to respond to an emergency in case of an emergency. That is, when a fire occurs, the operator can quickly extinguish the fire through the fire extinguishing device 30 provided in the mobile cart 100, and when it is difficult to extinguish the fire through the fire extinguishing device 30, the emergency It is possible to inform the outside of the emergency situation through the switch 60, and also, through the emergency kit box 20, emergency treatment is possible in case a worker is injured during work, so that it is possible to quickly respond to various emergency situations.

In actual construction sites, due to construction efficiency, economic feasibility, and demolition problems, the temporary firefighting facilities are provided only enough to satisfy the requirements of the law. Here, the facilities that directly consider the safety of workers can be seen as emergency warning facilities and simple evacuation guide lines. There is a limit to guide.

The present invention has been devised to overcome the problems of the prior art, and in particular, it is easily applicable even when a simple and temporary firefighting facility needs to be built, such as a construction site, and by enabling rapid and efficient evacuation of human life.

In addition, the output unit, it is possible not to miss the information from the gobo lighting device by notifying the evacuation worker that the guidance of the evacuation route is emerging on the floor at the same time as the fire evacuation alarm.

According to the present invention described above, it is possible to detect changes in the environment of the field according to the set function and perform active judgment by configuring the complex sensor unit and the gobo lighting device without the provision of complex facilities, and it is clearly intuitive and intuitive through the gobo lighting. Because it is possible to guide danger and evacuation, it is not only economical but also has the effect of dramatically improving safety.

In addition, since a plurality of complex sensor units each actively function while exchanging information with each other, and changing the information displayed by the gobo lighting device with light in response to the moment-to-moment change situation, human casualties can be minimized. In addition, it is easy to install and move faithfully to the purpose of the temporary firefighting facility at the construction site, and it has a high reliability effect because it can be flexibly adapted to the working environment.

Various applications are conceivable.

The structure has a complex space divided mainly by structures such as walls, bulkheads, and doors, and can be used by a large number of people, including large shopping malls, high-rise buildings, factory buildings, department stores, amusement parks, apartment houses, industrial facilities, as well as bridges, It may include various civil facilities such as tunnels and dams. As mentioned above, there is a problem that can detect various environmental changes that can threaten the safety of workers because firefighting facilities are not complete in the construction process of these structures, and a technology that can immediately and intuitively know this is required.

For this purpose, the present invention performs the above function by fusion of the complex sensor unit and the gobo lighting device, and an embodiment thereof will be described in detail.

The complex sensor unit 1000 is provided at each location of the structure to detect environmental changes including fire, generate a predetermined detection signal, and transmit this information to another complex sensor unit or the local management unit 2000 .

This complex sensor unit 1000 is installed in a predetermined selected position of the structure to detect fire, temperature, humidity, gas, fine dust, worker entry and exit, etc., perform a predetermined safety judgment, and gobo lighting device (3000) can be controlled, and specific examples thereof will be described later.

The installation position of the complex sensor unit 1000 may be basically selected and arranged on a ceiling or a wall. Considering that it is a construction site, installation on a pole or equipment may be considered.

The complex sensor unit 1000 is installed in a selected position of the structure to be able to individually detect, judge, and control operations, and is installed in a plurality of places to collect information in a centralized manner and send a predetermined alarm or notification. It can perform functions that are immediately provided to the field. As a preferred embodiment, the control server 2020 may be composed of a cloud server that can collect environmental information about the location of a plurality of structures and make a database remotely. It will be possible to remotely perform a function of storing and managing the sensed values or determination results as data in time series with a distinguished identifier for each complex sensor unit 1000 for each structure.

Through the control server 2020, an operator or manager may check predetermined status information with a terminal such as a smart phone, a tablet PC, or a PC.

In the case of a general structure construction site, unlike a completed building, wiring from a power source or a communication network is not completely established, so in consideration of this, between the complex sensor units 1000 and/or the complex sensor unit 1000 and The connection of the server unit 300 is preferably made in a wireless manner. For example, a case in which various wireless communication methods such as Zigbee, Bluetooth, RF communication, WiFi, 3G, 4G, LoRa (Long Range), Cat.m1 communication are applied may be considered. However, a wired communication method is not excluded, and a wired communication method such as a wired LAN or RS485 Modbus may be applied.

As a temporary firefighting facility according to a preferred embodiment of the present invention, the flow of guidance such as detection of fire in the complex sensor unit 1000, detection of entry and exit, determination of whether to evacuate or route, display to the gobo lighting device, or transmission of an alarm can be operated according to

If the area of the structure is wide and there are many places where the complex sensor unit 1000 is installed, a local management unit 2000 may be additionally provided to manage it by a predetermined local area, and via the local management unit 2000, It may be connected to the relay unit 2010 and the control server 2020. In addition, each complex sensor unit 1000 may communicate with other complex sensor units through the local management unit 2000 . However, since there are many combustible materials at the construction site and the securing of firefighting and disaster prevention facilities and evacuation routes are not properly implemented, each complex sensor unit 1000 is equipped with an individual response algorithm in light of the urgency and importance of the initial response in case of fire. A predetermined transceiver unit is provided to directly communicate with each other so that discrimination and information exchange are possible.

The relay unit 2010 may mean a communication network including a base station of a telecommunication company that provides mobile communication services such as CDMA, 3G, 4G, 5G, etc., but is not necessarily limited thereto.

Preferably, the gobo disposed at the emitting portion of the light has a filter having a plurality of information, and the filter can be selected or removed on the light path through the control of the actuator. By controlling the gobo of the gobo lighting device 3000, the complex sensor unit 1000 can illuminate information suitable for environmental changes from among the information previously set by the operator.

In the event of a fire, it may be considered to display information through a display such as an electric billboard or a simple light emitting lamp in some cases. However, in the case of a display, it is necessary to look directly at the display itself, and when smoke occurs, it is not easy to find and check information, and it is not simple and intuitive. In addition, there are also disadvantages in terms of equipment and management uneconomical. Also, in the latter case, the amount of information is limited.

When using the gobo lighting device 3000 as in the present invention, it is used for the purpose of lighting to secure the field of view in normal times, and when necessary, the selected information can be displayed by the functionalized operation of the complex sensor unit 1000, making it simple It is economical, and has intuitive and efficient advantages because it can provide information such as an evacuation route on the floor to workers who are lying on the floor or looking at the ground in a limited field of view when smoke or smoke is generated by a fire.

The output unit 1441 may be a speaker outputting sound and/or a lamp capable of emitting light, flashing, dimming, and the like. When the output unit 1441 is made of a speaker, it is possible to notify the operator of the occurrence of a fire and/or a predicted situation of a fire and/or information on whether or not to evacuate and/or an evacuation route through voice or an alarm sound. In addition, when the output unit 1441 is made of a lamp, it is possible to notify the user of the numerical values of the supply of power and the operating state and environmental information in a color or blinking manner, and in some cases, the output unit 1441 may display an image A case in which a display capable of outputting information of

In the management unit 1400 , the sensing value mainly related to fire and worker entry and exit, and information on the situation determined by the management unit 1400 and the command corresponding to the command are transmitted through the transceiver 1110 to the outside including the control server 2020 It can be mainly transmitted wirelessly to the devices of A duplicate description in relation to the communication method will be omitted. In this case, the external equipment may be one or more gobo lighting devices 3000 , and may also be other complex sensor units 1000 .

In addition, due to the nature of being installed at the construction site, it can be driven by its own power supply without external power supply, and it is advantageous to be detachable and movable as needed. case can be considered.

The management unit 1400 basically performs a determination of changes in the environment related to the occurrence of a fire in the structure, and can track the fire point, determine the evacuation route, and select the information exposed in the gobo lighting device 3000 . There will be.

4 is a block diagram for explaining an embodiment of the sensor module in the disaster evacuation guidance system using the gobo lighting of the present invention.

In the complex sensor unit 1000 , a plurality of sensors are configured in a module form, and various types of sensors may be combined to perform a function selected by the management unit 1400 .

A fire sensor 1214 may be provided to detect a fire, and the fire sensor 1214 may include a heat sensor or a smoke sensor, but is not necessarily limited thereto, and various sensors for detecting a known fire may be applied. will be able The fire sensor 1214 generates a fire detection signal and transmits it to the management unit 1400 to perform a basic determination as to whether a fire has occurred.

In addition, a temperature-humidity sensor 1211 may be provided to determine the basic construction work environment, and the temperature-humidity sensor 1211 detects temperature and/or humidity in a predetermined space and transmits the detection value to the management unit 1400 . do. The temperature detection value of the temperature-humidity sensor 1211 may function to track the heat source of a fire, and a plurality of complex sensor units 1000 may exchange detection values with each other to be used as a variable for mapping.

In addition, it may include a gas detection sensor 1212 for determining the toxic environment, the gas detection sensor 1212 is based on a CO sensor, but an O ₂ sensor, a CO ₂ sensor and / or PM (Particulate Matter) Sensors and/or formaldehyde sensors may be additionally or interchangeably disposed. In the case of the PM sensor, for example, sensors capable of measuring particles of different sizes (PM10, PM2.5, PM1.0, etc.) may be combined.

In addition, it may include an entrance/exit detection sensor 1213, and the entrance/exit detection sensor 1213 may detect an entry or exit of an operator at a predetermined entrance or occupancy, and transmit a detection value to the management unit 1400. The entrance/exit detection sensor 1213 may be, for example, a PIR (Passive Infra-Red) sensor.

In addition, the sensor module 1200 may include any one or more of a microphone for sound input and/or a vibration sensor for detecting vibration.

Meanwhile, in consideration of the efficiency of smoke detection, a case in which a fan module that actively forms a flow is applied to a predetermined through-hole in the housing to guide the inflow and outflow of air may also be considered.

The sensor module 1200 is installed on the board together with the management unit 1400, and may include pins or terminals of connectivity so that each sensor device can be selectively mounted.

5 is a block diagram illustrating a function of a management unit according to an embodiment of the present invention.

The management unit 1400 may receive the detection signal from the sensor module 1200, digitize it, and compare it with a predetermined set value to determine whether a reference value is exceeded or whether a condition is satisfied. As described above, promptness and accuracy of guidance in the event of a fire at a construction site are important factors for reducing casualties and property damage, and for this purpose, each complex sensor unit 1000 can operate with an individualized and optimized function. In some cases, it may be operated through the determination of artificial intelligence in conjunction with the management server 2020.

The management unit 1400 may include a fire determination unit 1413 , and may receive a fire detection signal from the sensor module 1200 to determine whether there is a fire or a situation that may harm the body. The detection signal of the fire sensor 1214, which is basically a smoke sensor, can function as a major variable for fire determination. The value, etc., may be used for fire judgment.

In addition, the management unit 1400 includes the entry/exit end unit 1411 and may determine the entry/exit relationship due to the presence or absence of an operator in the space where each complex sensor unit 1000 is installed or the presence or absence of an operation at the entrance. When a predetermined worker needs to be evacuated, the gobo lighting device 3000 may be actively operated for the worker who has not been evacuated according to the determination result of the input/output end unit 1411 to induce a quick evacuation.

The map setting unit 1420 is related to the arrangement of a plurality of complex sensor units 1000 that are interrelated and constitute one system, and may basically include location information set in advance for the environment inside the structure. In addition, the location information includes information on the location of the gobo lighting device 3000 and the irradiated location (mainly the floor).

However, considering that there may be many cases where it is difficult to set maps one by one because installation, removal, and movement must be easy due to the characteristics of temporary firefighting facilities, each of the complex sensor units 1000 is mesh-connected with each other and the transceiver Through the strength of the signal received by 1110, the distance relationship or the existence of obstacles may be updated in real time to actively create a map.

To this end, the interlocking unit 1430 may configure a connection relationship between the plurality of complex sensor units 1000 . This is defined as a mesh connection, and a one-stage connection relationship or a multi-stage connection relationship can be configured. Here, the multi-stage connection relationship means that a complex sensor unit connected only to another complex sensor unit in one complex sensor unit is connected via another complex sensor. If the structure of the building is complex or wide and there are complex sensor units that do not receive radio waves smoothly, this multi-stage connection relationship will be meaningful. When installed in a construction environment, each complex sensor unit can detect and identify a signal between each other according to the operation of the interlocking unit 1430, and each complex sensor unit (1000a, b, c, d in FIG. 2) ) can be assigned an individual identifier. The interworking unit 1430 may determine the interconnectivity of the complex sensor units 1000a, b, c, and d having respective identifier signals, and if the signal is weak, a multi-stage (partial) mesh network You can configure it to strengthen connectivity.

The map setting unit 1420 calculates the distance according to the identifier and signal sensitivity of each of the complex sensor units 1000a, b, c, and d, and can actively compose a map of the arrangement based on the triangulation result. will be. The plurality of complex sensor units 1000a, b, c, and d may share this map. In this way, when the composite sensor units 1000 have a mutually connected relationship, the location information of the composite sensor that generated the fire detection signal and the values of each temperature detection signal are matched to determine the fire point (F in FIG. 2) and spread. It will be possible to trace the route, and it is possible to establish a plan for the evacuation route.

Referring to FIG. 2 , by designating one layer as a unit area in a predetermined structure, the complex sensor units 1000 may constitute one system. A total of six rooms are divided and divided by location, and complex sensor units are arranged. Here, there is a staircase that can move to the upper and lower floors and an emergency staircase, one by one.

The fire point (F) is the hallway between the first and second rooms on the right, and it is assumed that the operator is located in the third room on the right. The fire point (F) is adjacent to the complex sensor unit 1000e of the first room and the complex sensor unit 1000d of the second room, and is a fire point through the difference in time or intensity of the detection signal generated by the smoke sensor or the heat sensor. prediction will be possible.

At this time, it is possible to determine occupancy by receiving the entrance/exit detection signal from the complex sensor unit 1000c of the third room from the right. The gobo control unit 1450 may operate as an evacuation mode to irradiate the information on the fire occurrence and evacuation direction to the floor in the gobo lighting device 3000 closest to the operator.

The interlocking unit 1430 is a diagram of the connection relationship between the respective complex sensor units 1000, as well as the connection relation between the gobo lighting devices 3000 and the connection relationship between the complex sensor unit 1000 and the gobo lighting device 3000. can be formed As in the illustrated embodiment, when the location of the worker who needs to be evacuated is confirmed, in the gobo lighting device 3000 (lower side) adjacent to the evacuation route, the gobo control unit 1450 to provide guidance on the occurrence of a fire and guidance on the evacuation direction at the same time. ) can be operated to control the gobo 3010, and the gobo lighting device 3000 located further away from this will be able to irradiate only the information for guiding the fire to the floor surface. In addition, as shown in the figure, it is possible to organically guide the evacuation route by selecting the filter of the gobo 3010 indicating the direction of the arrow appropriate for the evacuation route in each gobo lighting device 3000 .

As an additional embodiment, the interlocking unit 1430 may guide the output unit 1441 of the complex sensor unit 1000c where the operator is located, and guide the evacuation route from the gobo lighting device 3000 adjacent thereto. , the optimal evacuation guidance is possible by tracing the evacuation route of the worker through the judgment of the entry/exit judgment unit 1411 in each complex sensor unit and providing sound guidance at the same time as the gobo lighting. At this time, the output unit 1441 informs the evacuating worker that the guidance of the evacuation route is emerging on the floor at the same time as the fire evacuation alarm, so that the information from the gobo lighting device 3000 will not be missed. .

As described above, since the complex sensor units 1000 mutually exchange information on environmental changes by the interlocking unit 1430, the adjacent complex sensor unit 1000 will change with the passage of time according to the movement of the worker. . At this time, the subject of the complex sensor unit 1000 for controlling the gobo lighting device 3000 may be changed, and the interlocking unit 1430 is the gobo lighting device 3000 just before the complex sensor unit in which the worker's entry and exit is detected. It can function to take over the control authority from the controlling complex sensor unit.

The determination of the evacuation route and tracking and control may be performed by the control and evacuation determination unit 1414 . Since the evacuation route guided by the control and evacuation determination unit 1414 in conjunction with the gobo lighting device 3000 or the output unit 1441 is guided in the direction of the emergency exit or stairs adjacent to the fire point F, there is a threat to safety. If it is determined that it may occur, safety may be judged as a factor that takes precedence over efficiency. Accordingly, even if it is the most effective evacuation route, if it is impossible or unsafe to evacuate over time, it may be possible to determine another route. This may follow the update result of the real-time determination of the fire determination unit 1413 . In this case, it will be possible to switch the guidance to the next-priority evacuation route that leads to the emergency stair far from the fire point (F).

The information of the fire, evacuation route information, the presence or absence of a worker, the current location and movement of the worker collected from the composite sensor unit 1000 is a terminal such as a mobile phone via the local management unit 2000 or the control server 2020 It may be possible to directly transmit a text message or a disaster alert to the worker carrying the .

Meanwhile, in the present invention, an emergency evacuation facility may be additionally provided at the entrance or the evacuation route. For example, the emergency evacuation facility may be formed of a panel installed on a wall of a location where the entrance of the evacuation route is easy to use, and may include a warning light that can be used during an emergency evacuation. In addition, the emergency evacuation facility may have a manual operation switch to manually operate the gobo lighting device 3000 and/or the complex sensor unit 1000 . For example, the alarm unit 1440 may force the transmission of alarm information through the output unit 1441 in a manner such as voice, light emission, or display according to a manual operation of the operator.

On the other hand, as described above, the fire determination unit 1413 may determine whether a fire exists by calculating based on a received signal such as a year detection signal or a heat detection signal of the composite sensor unit 1000 at each location. A certain tracking algorithm may be applied in relation to the location of the fire. Referring to FIG. 2 , when a fire detection signal is transmitted only from one location 1000a, it may be determined that a fire has occurred in the corresponding room. However, as in the above example, when a fire occurs in the passage portion where the composite sensor unit 1000 is not disposed, the method of triangulation may be applied through the determination values of three or more points as a simultaneous determination. This function may be performed through the interlocking unit 1430, and it will be possible to determine which complex sensor unit 1000 the fire is closer to through the time difference and the strength of the detection signal. In addition, it will be possible to track the spread of fire through the time-series judgment.

In addition, the fire determination unit 1413 detects and predicts fire spread by changing or adding the location of the fire point F that is spread by the measurement of the fire sensor 1214 by the function of the interlocking unit 1430. will be able Accordingly, the control and evacuation determination unit 1414 determines and corrects the evacuation route based on the fire spreading over time and the location of the evacuee. Here, the spreading fire may mean only the flame itself, but should be understood as including the determination of the detection value for the toxic gas received through the gas detection sensor 1212 .

In addition, the control and evacuation determination unit 1414 may enable the gobo 3010 to be operated in the control mode of field access through the gobo control unit 1450 when it is determined that the operator is not at the site of the fire. In this case, the filter of the gobo 3010 is adjusted so that information about the occurrence of fire and access control, not the evacuation route, is investigated and exposed.

By configuring the complex sensor unit and the gobo lighting device without the provision of complex facilities by the disaster evacuation guidance system using the gobo lighting of the present invention described above, the environmental change of the field is detected according to the set function and active judgment is performed to provide the gobo lighting. It is economical and safety can be dramatically improved because it is clear and intuitive, and it is possible to guide danger and evacuation.

In addition, since a plurality of complex sensor units each actively function while exchanging information with each other, and changing the information displayed by the gobo lighting device with light in response to the moment-to-moment change situation, human casualties can be minimized. There is this.

In addition, faithful to the purpose of the temporary firefighting facility at the construction site, it is easy to install and move, and it is highly reliable because it can be flexibly adapted to the working environment.
