It should be interpreted as a meaning and concept consistent with the technical spirit of the present invention based on the principle that it can be.

Therefore, the embodiments described in this specification and the configurations shown in the drawings are only preferred embodiments of the present invention, and do not represent all of the technical spirit of the present invention, so various equivalents and equivalents that can replace them at the time of the present application It should be understood that variations may exist.

The overall structure of the accident response system (Damage Control System) having the function of the automatic fire suppression system to which the present invention is applied is shown in FIG. 11.

The accident response system for ships includes an onboard sensor data interlocking unit that collects data from detection sensors that detect ship accidents, an accident response system unit that operates the system based on accident response scenarios through sensor data input, and an accident response system unit. It is composed of the automatic fire suppression system part that interlocks the fire suppression equipment through the output control signal.

The inboard sensor data interlocking unit receives the output data of the heterogeneous sensors installed in the ship through the interface unit, converts it into a TCP/IP signal, and transmits the converted signal data to the accident response system unit.

This inboard sensor data interlocking unit consists of Main Control Unit, Digital Interface Unit, Serial Interface Unit, Analog Interface Unit, and Power Supply Unit, and each unit can be expanded or separated according to the number of contact points of input heterogeneous sensor signals.

The accident response system unit monitors the state information of heterogeneous sensors input through the inboard sensor data interlocking unit, and through this, detects an onboard accident and plays a role in operating an accident response scenario.

This accident response system consists of accident response scenarios, accident response system operation software, UI software, desktop PC, monitor, UPS (uninterruptible power supply), HUB (network distribution device), fire analysis DB, etc., and the output of the input sensor. Based on the data, the accident response scenario operates and the automatic fire suppression system operates according to the result of the interlocking fire analysis DB.

The automatic fire suppression system unit can be interlocked with signals so that operation signals can be input to the fire suppression equipment so that the fire can be automatically extinguished when the set suppression stage is reached through the risk assessment of the fire analysis DB included in the accident response system unit. equip the unit

It consists of Main Control Unit, Digital Interface Unit, Serial Interface Unit, Analog Interface Unit, and Power Supply Unit with the same configuration as the inboard sensor data interlocking couple. can be used

In the present invention, since the operation command data format of the fire suppression equipment is a device that operates by receiving digital contact output data, an automatic fire suppression system can be implemented by configuring a Main Control Unit, a Digital Interface Unit, and a Power Supply Unit.

Fire suppression equipment in the ship that can be operated through the command of the automatic fire suppression system department includes a fixed fire extinguishing main (fixed CO2 fire extinguishing system) installed in the engine room, engine room, oil storage, etc., sprinklers installed on each deck, fire doors, sliding door, etc.

Each equipment can control operation through On/Off contact output (Dry Contact, Wet Contact) data.

Extinguishing equipment for fire suppression is as follows.

Fire extinguishing equipment generally installed on ships can be largely divided into CO2 fire extinguishers, water-based fire extinguishers, and foam and foam fire extinguishers according to the medium that causes the fire extinguishing effect.

The CO2 fire extinguisher stores CO2 in a certain high-pressure container and sprays it on the fire in case of fire to cut off the oxygen supply to extinguish the fire.

In order to obtain the fire extinguishing effect, the target area must be sealed, and since there is a high risk of suffocation if there are people in the enclosed area, it is common to operate it manually after confirming that all personnel have evacuated.

A water-based fire extinguisher is a fire extinguishing device that extinguishes a fire by using complex phenomena such as cooling and lowering the oxygen concentration around inflammable materials by spraying water particles in the fire area. Depending on the size of water particles, it is divided into sprinkler and water mist.

Since there is no damage to human life even if there is internal life, it is common to install in a form that automatically operates when the part blocking the nozzle is removed when a certain temperature condition is reached. They are more suitable for general fires than oil fires and are mainly installed in residential areas.

Foam and foam fire extinguishers store fire extinguishing agents separately, and when the fire extinguisher is operated, the fire extinguishing agent and water are mixed to form foam or foam and sprayed on the fire area. It is a digestive system that

Since the fire extinguishing agent is stored separately from water, the size of the storage container is reduced. However, equipment exposed to foam and foam extinguishers is not used recently because they cannot be reused and can damage equipment that is not exposed to fire.

The Accident Response System (DCS) configured in this way provides information that predicts the future outcome of a fire accident in the event of a fire on a ship so that the optimal response can be made. When the fire develops to the highest risk, it plays the role of automatically activating the fire suppression equipment to extinguish the fire.

The preliminary fire analysis unit 10 serves to analyze a fire in the event of a fire by using vessel section information and a preset fire accident scenario and calculate a fire analysis result. That is, in the event of a fire using the ship section information and a preset fire accident scenario, the fire is analyzed using the location information of the ship where the fire occurred, and the analyzed fire analysis result is used to predict the fire outcome in the event of a fire in the future. The fire analysis result is stored in the database 20 so as to

Here, the results of the fire analysis can be calculated in the form of changes in calorific value, temperature, smoke generation amount, and smoke layer height according to the passage of time after a fire occurs.

The fire analysis result database 20 serves to store the fire analysis result data pre-analyzed by the preliminary fire analysis unit 10 .

The form of the fire analysis result database 20 is a Time Series Database (TSDB), but it is preferable to use a general relational database (RDB) in consideration of the structure for an important similar result prediction function and the computer operating environment of the applied vessel. do.

The fire accident detecting unit 30 serves to detect the occurrence of a fire on the ship and provide fire occurrence information to the fire result predicting unit 40 . Here, the fire occurrence information may include fire occurrence location information of the ship.

When a fire accident is detected by the fire accident detection unit 30, the fire result prediction unit 40 uses the fire analysis result stored in the fire analysis result database 20 based on the detected fire accident information to determine the fire result. It predicts, controls the expression of predicted fire analysis results, and calculates and provides the fire spread risk.

The fire result prediction unit 40 expresses the fire prediction result and extracts similar cases stored in the fire analysis result database 20 using fire occurrence location information based on the user response to the fire situation to cause a fire. Calculate the risk of fire spread, which is the hazardous state of the zone and adjacent zones.

The prediction result visualization unit 50 serves to express the fire analysis result under the control of the fire result prediction unit 40 . The prediction result visualization unit 50 is an interface device (GUI) for interface with a user.

The prediction result visualization unit 50 may superimpose and display the fire spread risk information on the drawing of the ship using different colors for each risk level so that the user intuitively recognizes the fire spread risk information.

The active fire response unit 60 serves to extinguish the fire by automatically operating a fire suppression device installed in the ship based on the risk of fire spread under the control of the fire result prediction unit 40.

The active fire response unit 60 automatically operates the fire suppression device of the ship directly when the risk of fire spread provided by the fire result prediction unit 40 exceeds the risk range set by the accident response system 100. suppress the

Here, the fire suppression device may include a sprinkler, a fixed fire extinguisher (CO ₂ ), and the like. The accident response system 100 and each fire suppression device installed on the ship are connected through a control line, through which remote control can be implemented.

The ship accident response system having an automatic fire suppression function according to the present invention having such a configuration can be applied to all ships, but in the present invention, for convenience of description, it will be described as an embodiment applied to a general ship (driveway ship).

The operation of the ship accident response system 100 having an automatic fire suppression function according to a preferred embodiment of the present invention configured as described above is described in detail as follows.

First, basic functions for responding to fire accidents and flooding accidents in the ship accident response system (DCS) 100 perform the same as those of the conventional ship accident response system.

The present invention adds an active fire suppression function for active fire suppression response in the event of a fire on a ship in addition to the basic response function for fire accidents and flooding accidents as described above.

For example, information predicting the future outcome of a fire accident is provided to the user so that an optimal response can be made, and in case of a fire, the risk of fire spread from the initial stage is linked with the fire analysis result database to determine the fire situation and user response plan. As a result, when the risk of fire spread exceeds the risk range set in the accident response system, the fire suppression device of the ship is automatically operated to extinguish the fire.

To this end, the preliminary fire analysis unit 10 analyzes the fire by using the location information of the ship where the fire occurred when a fire occurs using the ship division information and the preset fire accident scenario, and the analyzed fire analysis result is later When a fire occurs, it is stored in the fire analysis result database 20 to be used for predicting fire results.

Then, when a fire breaks out in a specific place during ship operation, the fire accident detection unit 30 detects the fire, generates fire occurrence information, and sends it to the fire result prediction unit 40 through a multi-cast packet. deliver in real time. Here, since the fire occurrence information includes fire occurrence location information, when a fire occurs simultaneously in several places in a ship, a plurality of fire occurrence information corresponding thereto also occurs.

When a fire accident is detected by the fire accident detection unit 30, the fire result prediction unit 40 uses the fire analysis result stored in the fire analysis result database 20 on the basis of the detected fire accident information. Predict the result and control the display of the predicted fire analysis result.

The prediction result visualization unit 50 displays a fire analysis result under the control of the fire result prediction unit 40 . Here, the prediction result visualization unit 50 may superimpose and display the fire spread risk information on the drawing of the ship using different colors for each risk level so that the user intuitively recognizes the fire spread risk information.

2 is an example of an interface between a user and the fire result prediction unit 40 .

The user (DCS user), the operator of the ship accident response system, recognizes the fire outcome prediction information through the prediction result visualization unit 50 as described above, gives necessary instructions for each step according to a preset demo scenario, and responds with response instructions is input to the prediction result visualization unit 50, which is an interface device (GUI). The prediction result visualization unit 50 transmits the response guideline response to the fire result prediction unit 40 through a predefined multicast packet.

The fire result prediction unit 40 displays a fire prediction result, and similar cases stored in the fire analysis result database 20 using fire occurrence location information based on a user response (response guideline response) to the fire situation. It is extracted to calculate or change the risk of fire spread, which is the risk state of the fire area and nearby areas.

The calculated or changed fire spread risk information is displayed on the screen through the prediction result visualization unit 50 so that the DCS user can recognize it in real time.

Here, it is assumed that the fire result prediction unit 40 continues to expand until the fire is extinguished by using the fire location information generated by the fire accident detection unit 30 even if there is no response from the user, and the flow of time The risk level is continuously updated.

Here, the accident response system 100 of the present invention divided the risk of fire spread into three stages.

That is, as shown in FIG. 3, when a fire occurs at the bridge location, fire accident occurrence information is transmitted to the fire result prediction unit 40 (S101). The fire result prediction unit 40 calculates the fire spread risk in conjunction with the fire analysis result database 20 based on the transmitted fire accident location information using the fire spread risk calculation algorithm as shown in FIG. 5 .

12 is a conceptual diagram for predicting fire risk in the fire risk predictor 40.

Calculate the allowable evacuation time (ASET - Available Safe Escape Time), which is the risk limit of smoke and temperature calculated by fire analysis, and the evacuation time (RSET - Required Safe Escape Time), which is the evacuation movement time of passengers in the ship calculated by evacuation analysis and compare the two times to assess the risk.

When evaluating fire safety, the basic principle is to ensure that people can escape the area before the smoke, toxicity, and temperature from the fire rise to unhealthy levels.

13 shows a concept for this. Fire Growth represents the growth process of fire.

From the point at which the fire grows to a certain scale after the first ignition, the fire causes damage to life, and when this is called Time to hurt occupant, the evacuation time available to the user is It can be viewed from the time of detection (Discover Fire) to Time to hurt occupant. In other words, if the time required for evacuation (Required Safe Egress Time; RSET) is longer than the available safe egress time (ASET), human life is not guaranteed even if the user is aware of the fire. It is judged that it is a dangerous situation that causes

The determination of the risk level through fire risk prediction is shown in FIG. 14.

Here, the input values are Deck/Position/People/Time/Destination/1N-Area(Time)/2N-Area (Time), and the output values are ASET/RSET.

That is, the fire spread risk is determined by confirming the location of the fire and the type of fire.

Risk level 1 is a caution level and is expressed as visualization information as shown in FIG. 15 .

This is the stage of initial suppression from the time of fire occurrence, and the evacuation allowable time (ASET) has more margin than the evacuation possible time (RSET). The fire occurrence time continues to increase and the allowable evacuation time continues to decrease.

Accident elapsed time: 02 minutes and 14 seconds elapsed

ASET (23m 46s) > REST (15m 00s)

When the risk information on the risk level 1 is displayed on the prediction result visualization unit 50, the DCS user issues a response guideline for fire suppression according to the response guideline.

8 is an example of a screen for receiving and displaying risk information of risk level 1, which is an initial stage of fire.

Here, the risk data structure displayed on the prediction result visualization unit 50 is as shown in FIG. 4A. The meaning of each risk ID shown in FIG. 4A is serious if the risk ID is 0x01, dangerous if it is 0x02, and caution if it is 0x03.

After that, a corresponding guideline response is input through the GUI.

The fire result prediction unit 40 checks the corresponding guideline response input through the GUI, and if it is in the initial suppression state (S103), determines that the initial suppression has succeeded (S104), and moves to the situation standby step (S105) .

If, as a result of checking the response guideline response, it is determined that the initial suppression has failed, the fire spread risk level is changed to the second level, and the situation is disseminated to the outside by broadcasting a VHF fire (S106).

Risk level 2 is a warning level, and is expressed as visualization information as shown in FIG. 16.

This is the stage in which the fire continues to progress because the initial suppression fails after a fire occurs or the occurrence of a fire accident is not recognized, and if the evacuation allowable time (ASET) remains less than the evacuation possible time (RSET), there is a possibility of human casualties. am. The fire occurrence time continues to increase and the allowable evacuation time continues to decrease.

Accident elapsed time: 10 minutes and 30 seconds elapsed

ASET (14 min 30 sec) < REST (15 min 00 sec)

9 is an example of a screen for receiving and displaying risk information when the fire risk level rises to level 2 when the initial fire suppression fails during fire suppression.

In addition, DCS users have response guidelines according to fire spread risk level 2. For example, putting the response team (fire extinguishing team) into the fire place (S110), crew emergency deployment (S107), issuing a fire alarm and closing the fire area, stopping the engine, stopping the oil supply, closing the ventilation, emergency steering, and evacuating personnel from the fire area Response guidelines such as emergency response (S108), passenger evacuation broadcasting, passenger evacuation guide personnel arrangement, and passenger evacuation (S109) such as passenger evacuation confirmation are given.

Afterwards, response guidelines are given to the input of the response team.

The fire result prediction unit 40 checks the response guideline response to the fire spread risk level 2 input through the GUI, and when it is determined that the fire suppression was successful by the response team (S111), the final fire suppression was successful. It is determined that (S113), and a fire suppression report is prepared (S114).

Unlike this, the fire result prediction unit 40 checks the response guideline response to the fire spread risk level 2 input through the GUI, and when it is determined that the fire suppression has failed by the response team, the fire spread risk level 3 information is generated and displayed on the GUI and at the same time provides information of fire spread risk level 3 to the active fire response unit 60.

Risk level 3 is a serious level and is expressed as visualization information as shown in FIG. 17 .

This is the stage in which the fire spreads to other compartments when the fire suppression through the introduction of the response team fails or the occurrence of the fire accident is not recognized. The allowable evacuation time (ASET) has been exhausted, and human casualties are likely to occur. When the risk level enters Level 3 (severe level), the fire suppression system automatically operates and activates the fire suppression equipment equipped on board.

Accident elapsed time: 25 minutes 00 seconds elapsed

ASET(00m00s) < REST(15m00s)

10 is an example of a screen for receiving and displaying risk information when the fire spread risk level rises to 3 due to failure of fire suppression by a response team. In this case, the automatic fire suppression function is performed.

The active fire response unit 60 suppresses the fire by automatically operating a fixed fire suppression device installed on the ship according to the control of the fire result prediction unit 40 (fire spread risk level 3 information) (S112).

That is, when the fire spread risk provided by the fire result prediction unit 40 exceeds the risk range set by the accident response system 100 (fire spread risk level 3), the active fire response unit 60 automatically Extinguish the fire by activating the fire suppression system directly.

Here, the fire suppression device may include a sprinkler, a fixed fire extinguisher (CO ₂ ), and the like. The accident response system 100 and each fire suppression device installed on the ship are connected through a control line, through which remote control can be implemented.

7 is an example of a junction box for transmitting an operation signal to fire extinguishing equipment located remotely in the accident response system 100. In the accident response system 100, sprinklers, fixed fire extinguishers, and the like provided in the ship can be remotely controlled through the selected ship box.

6 is a configuration diagram for driving fire extinguishing equipment located remotely in the accident response system 100.

The fire extinguishing equipment driving signal generated in the accident response system 100 is received by the fire extinguishing equipment controller 210, and the fire extinguishing equipment controller 210 operates the sprinkler driver 240 to operate the associated sprinkler 2050 to fire. put pressure on...

In addition, the fire extinguishing equipment controller 210 operates a fixed fire extinguisher (CO ₂ ) provided in the carbon dioxide storage room 220 to emit carbon dioxide to extinguish the fire.

Carbon dioxide generated from the fixed fire extinguisher is supplied to the engine room or the engine room through the connected pipe, and automatically extinguishes the fire occurring in the corresponding room.

Thereafter, the final fire suppression situation is checked, and if the final fire suppression is successful, the fire and suppression report generation step is performed (S114), and, unlike this, if the final fire suppression is not successful, the ship is abandoned (S115).

According to the present invention described above, when a fire occurs on a ship, the future result of the fire accident is provided as predictive information so that the optimal response is made, and after providing the predicted result, the fire situation is continuously monitored to determine the risk level, and the fire is the highest When it develops to a dangerous level, it is possible to extinguish the fire by automatically driving the fire suppression equipment, thereby ensuring the safety of the ship from fire.

In addition, according to the present invention, when a ship fire occurs, the risk of spreading the fire is predicted, and when the predicted risk of spreading the fire exceeds the risk range set in the accident response system, the fire suppression device of the ship is automatically operated to extinguish the fire. can
