Description

Real-time training information and gas information measurement device and training situation and gas distribution situation monitoring system using the same {APPARATUS FOR MESURING TRAINING INFORMATION AND GAS INFORMATION IN REAL TIME AND MONITORING SYSTEM FOR TRAINING SITUATION AND GAS DISTRIBUTION SITUATION USING THE SAME}

An embodiment of the present invention relates to a training information and gas information measuring device and a training situation and gas distribution situation monitoring system using the same, and more specifically, air consumption, location information, and heart rate measurement information for training members participating in fire training. A training information and gas information measuring device that measures and provides training information in real time, such as gas quantity and gas distribution situation, in real time, assuming that gas is distributed in the space to training members participating in the training, and This relates to a training situation and gas distribution situation monitoring system using this.

In the past, when firefighters were extinguishing fires, firefighters could not tell where they were due to smoke or noise, or fellow firefighters had to search for a way to rescue firefighters who were in danger due to an accident. However, the reality is that there are cases where fellow firefighters are also in danger while rescuing firefighters whose exact location is not known.

Accordingly, recently, in order to overcome these problems, a location detection system has been implemented to identify the location of firefighters in danger and easily rescue them when extinguishing a building fire.

However, even if a system has been introduced to identify the on-site location of firefighters and easily rescue firefighters exposed to dangerous situations based on this system, many firefighters who die on-site are notified of their location. Cases that result in accidents due to failure to overcome dangerous situations frequently occur. For example, firefighters must constantly be aware of the amount of oxygen they have, but in dangerous situations, they may face difficulties if they are unable to properly check the oxygen amount.

Therefore, before being deployed to an actual fire suppression situation, firefighters are able to conduct firefighting training by reproducing a fire situation that is close to the actual situation through a simulator. For example, according to the Fire Service Act, fire drills are mandatory to be conducted at least once a year for buildings over a certain size. These fire drills are crisis situation training assuming an actual fire situation and are conducted to strengthen actual response capabilities. It is becoming.

In addition, when gas is distributed within a space, it is necessary to monitor in real time areas where high concentrations of gas are distributed and areas where gas concentrations are relatively low or where no gas exists so that trainees can avoid gas sections as much as possible. Despite its size, there is no such training system in place.

Oxygen tank pressure MAX BAR = 300 BAR

Maximum charging air volume of oxygen tank: 300 BAR * 6.8L (internal volume) = 2040L

Trainer air consumption (e.g. when training drops to 250 BAR for 45 minutes): 250 BAR * 6.8L = 1700L, i.e. 2040L - 1700L = 340L

Air consumption during 45 minutes of training: 340 L

Converted to per minute, 340:45 = x:1, so x = 7.5L

Final consumption per minute: 7.5L used per minute.
