OBSERVATION SYSTEM FOR PERSONAL SAFETY OF FIRE FIGHTER

The present invention relates to a firefighter's safety system, and more particularly, to the personal safety of firefighters that can continuously monitor the surrounding hazards, including the amount of oxygen held by the firefighter, and can perform safety instructions and guidance from outside according to the monitoring results. It relates to a surveillance system.

In general, the firefighters had to visit their fellow firefighters to find out how to rescue the firefighters who were in danger due to accidents or noises. However, it is a reality that fellow firefighters are in danger while rescued firefighters who do not know the exact location.

Therefore, recently, a location detection system has been implemented to easily locate and rescue firefighters who are in danger of extinguishing a fire in a building.

First, Figure 1 is a state diagram schematically showing a conventional firefighter positioning system, Figure 2 is a block diagram showing a firefighter positioning system. Referring to this, the firefighter positioning system, the transmitting unit 110, the receiving unit 120, the positioning unit 130, the display unit 140, the main processing unit 150, the voice transmission wireless system 160 ) And database 170.

The transmitter 110 includes a sensor attached to the equipment worn by the firefighter to detect movement and position, and transmits the value extracted from the gyro sensor 112 and the acceleration sensor 114 as a means for transmitting the detected value. Done. The gyro sensor 112 extracts the angular acceleration value and is a sensor for detecting the movement of the firefighter on the x y coordinate.

The acceleration sensor 114 extracts the gravity acceleration value, and detects the height of the firefighter on the z-coordinate. Therefore, the position of the firefighter can be accurately determined by the gyro sensor 112 and the acceleration sensor 114. In addition, the transmitter 110 is given a unique identification number of each firefighter is stored in the database 170. The receiver 120 receives the motion information extracted by the sensor.

The position detecting unit 130 captures the movement from the sensor value received by the receiving unit 120 using the (x, y, z) coordinates, and compares it with the reference coordinate value stored in the database 170 to the firefighter. Know the location of the. The display unit 140 displays the captured motion on the screen using the (x, y, z) coordinates.

The main processor 150, when a firefighter falls down and does not change the sensor value for a predetermined period of time or when the firefighter himself is in an emergency situation, and requests an emergency rescue, the identification number of the firefighter lights up and the emergency rescue Make a beep to call for rescue. The voice transmission wireless system 160 is a system for receiving the emergency rescue signal and requesting assistance to other firefighters.

Therefore, the above-described conventional firefighter positioning system, because when the firefighter is inadvertently accidentally, do not convey his position accurately in a panic or the voice transmission radio system is broken, it is determined exactly where the firefighter is located. In addition, when a fire fighter has an accident during firefighting, the voice transmission radio system is used to contact a nearby fire fighter to help rescue or to be rescued by a fire fighter standing outside the building.

However, in this way, the location of the firefighters can be identified and the firefighters who are exposed to the dangerous situation can be easily rescued based on this, and many firefighters who are in the field overcame the danger situation even though they are notified of their location. It is not leading to an accident.
