The engine room temperature sensor 110 detects the temperature inside the engine room when the vehicle is continuously parked in the open air or the engine is overheated during high-speed driving in a dry, high-temperature summer season. Data is transmitted to UNO R3 (500). At this time, the temperature data detected by the engine room temperature sensor 110 is compared to the reference value in the ECU and transmitted to the temperature indicator of the vehicle clusters, and to the Arduino UNO R3 500 that can communicate with the ECU at the same time. It is possible to transmit.

The engine room fire detection sensor 120 performs the same function as the engine room temperature detection sensor 110. In particular, when a fire occurs in an engine room of a vehicle, the engine room fire detection sensor 120 may be caused by a fire. By changing the flame or brightness in the engine room to a resistance value, the fire detection signal is directly transmitted to the Arduino UNO R3 (500), and the Arduino UNO R3 (500) is compared with a previously programmed reference resistance value. If the calculation process is greater than or equal to a reference value, a drive control command is issued to the solenoid valve drive drive 200 to inject the abc fire extinguishing powder 300 as a sound insulation material.

The external collision detection sensor 130 performs the same function as the engine room temperature detection sensor 110 and transmits the collision detection data to the ECU of the vehicle when the vehicle crashes during driving.

2 and 3, the solenoid valve drive drive 200 is a means for injecting the sound-absorbing material abc fire extinguishing powder 300 in response to the drive control command of the Arduino UNO R3 (500), the present invention In an embodiment of the present invention, since four abc fire extinguishing powders 300 are installed in the engine room bonnet of a vehicle, the solenoid valve driving drive 200 is also equipped with a total of four abc fire extinguishing powders 300, respectively. It is assumed.

In addition, the solenoid valve drive drive 200 receives the driving control command of the Arduino UNO R3 in accordance with the burn-in stage in the initial stage of the fire in the engine room of the vehicle, and the abc fire extinguishing powder combined with the sound insulation material installed in the engine room bonnet. The solenoid valve drive drive is mounted on each of the soundproofing material abc fire extinguishing powder so that the injection can be selectively performed one by one out of all four.

Here, the classification of the degree of fire occurrence from the initial stage to the total combustion stage is based on a reference value pre-programmed in the Arduino UNO R3 500 to change the resistance value input from the engine room fire detection sensor 120. Operation processing is possible.

The sound-absorbing material abc fire extinguishing powder 300 according to an embodiment of the present invention is characterized in that it can be extinguished step by step according to the engine room fire range of the vehicle and can increase noise isolation of the engine room.

Here, the powder fire extinguishing agent is a drug that extinguishes by making a fine powder of substances such as sodium hydrogen carbonate, potassium hydrogen carbonate, and ammonium monophosphate to increase fluidity and then ejecting it at a gas pressure (mainly N2 or CO2 pressure). The particle size of the powder used is in the range of 10 to 70 μm, and the particle size showing the optimal extinguishing effect is 20 to 25 μm. Since the powder fire extinguishing agent reacts with moisture and solidifies, moisture-proof processing must be performed with metallic stearic acid leaves or silicone resins (currently, most silicone resins are used) to prevent this. Powder fire extinguishing equipment is divided into axial type and pressurized type according to the filling state of pressurized gas. The accumulator type is a method of filling the medicine storage tank with powdered extinguishing agent and then filling the pressurized gas together, and the pressurized type installs a pressurized gas container separately from the medicine storage tank to inject it into the medicine storage tank to release the medicine to the outside. Way.

Therefore, in the present invention, any one of an accumulator type or a pressurized type is selected inside the sound insulation material mounted on the lower part of the engine room bonnet to store the powder fire extinguishing agent. At this time, a separate means is taken to prevent the high temperature of the engine room from being transmitted through shock and sound insulation from the outside of the bonnet.

When a fire occurs in the engine room, the engine room fire detection sensor 120 and the Arduino UNO R3 500 inform the powder fire extinguishing agent of the abc fire extinguishing powder 300, which is a sound insulation material, is being normally sprayed. The emergency flashing and alarm functions are performed so that the driver can easily check the vehicle interior while driving.

Here, since the navigation 400 has a kind of display function that displays driving information and geographic information of the vehicle, the Arduino UNO R3 500 is based on the data detected by the engine room fire detection sensor 120. The navigation so that the solenoid valve drive drive 200 is driven and controlled to display digitally from the operation sensing of the solenoid valve drive drive 200 that the powder fire extinguishing agent of the soundproofing material abc fire extinguishing powder 300 is normally sprayed. 400. In addition, the emergency flashing or alarm function in the navigation 400 is also pre-programmed in the Arduino UNO R3 500, and the Arduino accepts input values from various switches or sensors to control and control these external functions. It is a small computer designed from scratch.

2 and 3, the Arduino UNO R3 500 is a means for controlling the entire automatic fire extinguishing device using the engine room bonnet sound insulation material of the vehicle according to an embodiment of the present invention, the engine brain of the vehicle The information can be collected through communication with a corresponding ECU (Electronic Control Unit), and the data transmitted from the engine room fire detection sensor 120 of the fire detection sensor 100 is calculated and processed to operate the solenoid valve drive drive 200 In order to issue a driving control command to the driving control to display the fire situation on the navigation (400).

In other words, when the fire occurs in the engine room of the car, the Arduino UNO R3 500 causes the engine room fire detection sensor 120 to change the degree of flame or brightness due to fire in the engine room to a resistance value. By directly transmitting the fire detection signal to the Arduino UNO R3 (500), the Arduino UNO R3 (500) performs a comparison operation process with a pre-programmed reference resistance value, and the solenoid valve drive drive ( 200) to deliver the driving control command to spray the abc fire extinguishing powder 300 for the sound insulation material. And, while driving, it enables the driver to visually check the fire situation and injection of the powdered fire extinguishing agent through the navigation inside the vehicle through digital graphics and emergency flashing or alarm functions.
