Description

Fire suppression system and its control method {FIRE SUPPRESSION SYSTEM AND CONTROLL METHOD THEREOF}

The present invention relates to a fire suppression system and a method which can be mounted in a vehicle or a building such as a railroad or a subway to detect and extinguish early when a fire occurs. In particular, all operations until a process of detecting and extinguishing a fire are automatically performed. On the other hand, the present invention relates to a fire suppression system and a method for notifying fire occurrence by directly operating a warning facility by a user who manages a passenger or a central monitoring system in a vehicle regardless of the operation of a fire detection sensor.

In general, railway and subway vehicles are used by a large number of passengers and have high-speed characteristics, so that a fire may lead to a large-scale personnel accident. Fire extinguishers are installed at the location to allow passengers to manually extinguish small fires, and facilities for manually opening the door of the vehicle as an evacuation means and facilities for communicating with the engineer of the vehicle are installed. .

However, since a large number of passengers are in the railway and subway cars, the space inside the vehicle is narrow, which makes it difficult for passengers to extinguish the fire in the event of a fire, making it difficult to operate a fire extinguisher or open the door of the vehicle manually. I had a problem that things could happen.

On the other hand, in the case of fire-fighting facilities installed in the building it is widely used to detect the fire through the smoke detector and to spray water by operating the sprinkler during the fire detection. However, when the smoke detector is not working due to aging, the fire fighting facility does not work at all, there is a problem that can be unnecessarily contaminated the site if the smoke detector is operated even when no fire occurs.

Accordingly, the present invention has been made to solve the conventional problems as described above, an object of the present invention is installed in a vehicle or building, such as railways and subways that can be suppressed automatically in the event of a fire suppression system and its control method To provide.

Another object of the present invention is to provide a fire suppression system and a method of controlling the same, which can operate a bell plant by directly controlling the control unit by a user of a central monitoring system or a passenger at a fire site when a fire occurs.

Still another object of the present invention is to provide a fire suppression system and a control method thereof, which have excellent fire detection performance and have improved fire suppression accuracy.

The operation of the fire suppression system according to the embodiment of the present invention configured as described above will be described.

3 is a flowchart for controlling a fire suppression system according to an embodiment of the present invention, where S means a step.

First, the control unit 200 monitors the mode (automatic mode / manual mode) and its own mode (automatic mode / manual mode) of the central monitoring system 500 (S1), and determines whether both modes are auto mode. (S2).

If both modes are the automatic mode (YES) in step S2, the control unit 200 determines whether the check method is a single check or a cross check-in (S3).

In the case of the single check method in step S3 (YES), the controller 200 determines whether any one of the smoke detector 100, the heat detector 110, and the image detector 120 detects a fire occurrence. (S4).

If all of the detectors do not detect a fire occurrence in step S4 (NO), while repeating the step S4, while any one of the detectors detects a fire occurrence (YES), the controller 200 By operating both the first and second switches 300 and 310 to turn on both the seedling facility 400 and the mist spraying facility 410 to notify the fire and spray the steamed water to extinguish the fire (S5). At the same time, the control unit 200 notifies the central monitoring system 500 of the current situation.

On the other hand, when the cross check method (NO) in step S3 (NO), the control unit 200 determines whether the heat sensor 110 or the image sensor 120 detects the fire (S6).

If both detectors do not detect a fire occurrence in step S6 (NO), while repeating this step S6, while detecting one of the two detectors (YES), the controller 200 It is determined whether the smoke detector 100 detects a fire occurrence (S7).

If the smoke detector 100 does not detect a fire occurrence in step S7 (NO), the process proceeds to the step S6, while if the smoke detector 100 detects a fire (YES), the step S5 Proceeds to.

Meanwhile, when at least one of the mode of the central sensing system 500 and the controller 200 itself is the manual mode in step S2 (NO), the controller 200 selects an operation selection key of the key signal input unit 130. It is determined whether or not the control signal input from the central monitoring system 500 is the on operation signal by the on operation signal (S8).

In step S8, the control unit 200 repeatedly performs this step S8 when the setting state of the control unit or the control signal from the central monitoring system 500 indicates that the plant is off (NO). When the control signal of the central monitoring system 500 indicates on (YES), the first switch 300 is turned on to operate the alarm facility 400 on (S9), and together with the central monitoring system 500 Notify

As described above, according to the fire suppression system and the control method thereof according to the present invention, all operations are automatically performed when a fire occurs, so that the fire can be suppressed at an early stage.

Another effect of the present invention is to directly control the operation switch of the key signal input unit or to the control signal from the central monitoring system in any of the modes of the control unit or the central monitoring system regardless of the operation of the smoke detector, the heat detector and the image detector. It is possible to notify the occurrence of fire by operating the alarm system.

Another effect of the present invention is that even if any one of the smoke detectors, heat detectors and image detectors can operate the seedling facility and the mist sprayer to extinguish the fire.

Another effect of the present invention is that if the check method of the control unit of the detector is set to the cross-check state, even if the smoke detector is malfunctioning due to aging smoke detectors and mist sprayer can operate only the heat detector or the image detector can operate the fire alarm system and the mist spraying system unnecessary fire suppression Is to avoid.
