The present invention relates to a fire drill simulation system and a control method thereof, and more particularly, to a simulation system and a control method for firefighters to perform a fire drill by reproducing a fire situation close to a real situation through a simulator. .

In the firefighting training of firefighters, the safety of firefighters has been threatened as a method of using actual combustible materials (abbreviated as real materials) such as synthetic resin and wood has been mainly performed. In other words, the production of training situations using demonstration materials may lead to unexpected flame expansion during fire suppression training, and may lead to a true story, and there is no means to adequately cope with this. I had this emerging problem.

Therefore, in an effort to solve this problem, a fire fighting simulator was developed to reproduce the fire situation using natural gas. Such a simulator is comprised so that a burner may be installed in a fire generating part and the gas supplied from a gas tank to a fire generating part may be controlled appropriately. But in these simulators, there was still a problem with the stability of the training. In other words, since gas is used as a fuel source, there is a risk of uncontrollable conditions due to the failure of the gas supply system when a fire situation is generated, which may cause unexpected fires to injure adjacent firefighters injured in training. Have

In addition, since the flame is provided in the usual form, since the fire situation is formed only by the degree of the occurrence of a simple flame, there is a difference from the real fire, which is accompanied by a problem of low efficiency of fire drills.

In particular, the conventional simulator had a high risk of explosion in case of gas leakage. That is, when gas leakage occurs due to damage to the gas system, external shock, or the like, the leaked gas is concentrated and accumulated in the lower portion. In this case, since the conventional simulator uses a control valve using electricity, the leakage gas is ignited at the initial stage of operation of the simulator, which may cause an explosion.

Accordingly, the present invention has been made in view of the above problems, the object of which is to simulate the fire extinguishing fire by inserting a fire extinguishing agent while blocking the supply gas by detecting it during the unexpected expansion of the fire during training. It is to provide a system and a control method thereof.

Still another object of the present invention is to provide a fire drill simulation system and a control method thereof, which can increase the efficiency of fire drills by replaying the fire in a form similar to a real fire by sequentially expanding the flames.

The injection means preferably comprises an area of the first combustion section 50 and consists of a plurality of nozzles. The nozzle is preferably arranged at the boundary of the third combustion section 70.

Reference numerals 12b, 14b, 16b, and 18b, which are not explained, are regulators for adjusting gas pressure, and 12c are safety valves.

The operation of the fire drill simulation system in the present invention having such a configuration will be described with reference to the flowchart of FIG. 2.

The main valve 12a and the first valve 14a are opened to supply gas from the gas tank 10 to the first combustion unit 50 (S10).

The first burner 50 is ignited using a pilot burner (not shown) (S20). The pilot burner is ignited by a power source controlled by the control unit.

The temperature of the first combustion unit 50 is measured by the first temperature sensor 52 and compared with the first set value of the first combustion unit (S30). The first set value is set to a temperature that can be judged when a normal gas flame is burning.

If the temperature of the first combustion unit 50 is lower than the first set value, the ignition is continued. If the temperature of the first combustion unit 50 is higher, the second valve 16a is opened to ignite the second combustion unit 60 (S40). At this time, the second combustion unit 60 is ignited by the flame of the first combustion unit.

The temperature of the second combustion unit 60 is measured by the second temperature sensor 62 and compared with the first set value (S50).

If the temperature of the second combustion unit 60 is lower than the first set value, the ignition is continued, and if the temperature of the second combustion unit 60 is high, the first valve 14a is blocked to extinguish the first combustion unit 50 (S60).

Subsequently, the third valve 18a is opened to enlarge the flame of the second combustion unit (S70). The opening of the third valve increases the gas supply to the second combustion unit 60, so that the flame is increased in proportion.

The temperature of the second burner is measured by the second temperature sensor 62 and compared with the second set value of the second burner 60 (S80). At this time, the second set value is the temperature of the state of the flame suitable for performing the fire training mode.

If the temperature of the second combustion unit 60 is lower than the second set value, the ignition is continued, and if the temperature of the second combustion unit 60 is high (S90).

Next, the first temperature is measured by measuring the temperature of the third combustion part by using a third temperature sensor 72 disposed at a position spaced apart from the second combustion part 60 by a predetermined distance, and the first measured value is measured by the third temperature. It compares with the 1st set value of a combustion part (S100). The first set value of the third burner is set to a temperature value at which the degree of fire in the third burner is judged to be out of the normal range. Preferably, the first set value of the third combustion section is set to 1000 ??.

If the first measured value of the third combustion unit 70 is lower than the first set value of the third combustion unit, it is determined that the fire of the second combustion unit 60 has been suppressed by fire fighting and the training mode is terminated. Blocking both the main valve 12a and the first, second, and third valves, and a high value means that the fire is continuously being developed without suppression by the firefighter in training, and the main valve 12a and the first, At the same time shut off both the two and three valves and generates an alarm (S110, S120).

Subsequently, the temperature of the third combustion unit 70 is measured by the third temperature sensor 72 to obtain a second measured value, and the second measured value is compared with the first measured value (S130).

When the second measured value is lower than the first measured value, the training mode is terminated by shutting off all valves, and when the second measured value is higher, the fourth valve 22 is opened to inject the extinguishing agent of the fire extinguishing tank into the second combustion unit (S140). . The extinguishing agent is immediately supplied to the second combustion unit 60 through the extinguishing agent supply pipe 24.

Subsequently, the temperature of the third combustion unit 70 is compared with the second set value of the third combustion unit (S150). The second set value of the second combustion unit 60 is set to a temperature value at which the temperature of the third combustion unit is determined to the extent that no flame exists. If the temperature of the third combustion unit 70 is lower than the second set value, the fire extinguishing mode continues, and if it is low, it is determined that extinguishing is completed by the addition of the extinguishing agent and the training mode is terminated. It is preferable to set the second set value of the third burner to 100 ??.

 As described above, the fire drill simulation system and control method according to the present invention are equipped with a first combustion unit and a second combustion unit to supply and control gas through different paths, thereby creating a situation similar to that of a real fire.
