Description

A kind of safe and intelligent protective fire-fighting clothing

technical field

The invention belongs to the technical field of protective functional clothing, in particular to an intelligently regulated safety protective fire-fighting clothing and a control method thereof.

Background technique

As we all know, firefighting clothing belongs to the protective clothing worn by firefighters in the process of fire rescue. Its use scene is a harsh environment where open flames, thick smoke and high temperature and high radiant heat are combined. Thermogenic phenomenon. Moreover, during the rescue process, firefighters also have to engage in high-intensity activities such as climbing and rescue, carrying heavy objects, and brisk walking and sprinting, which further aggravates the body's heat generation and sweat discharge. If the large amount of heat and sweat produced by the body cannot be eliminated in time, it is easy to cause the core temperature of the human body to rise to a dangerous critical temperature (40°C) within the tolerance range of the human body. Therefore, it is very necessary to develop fire-fighting clothing with functions of thermal perception and intelligent regulation of the temperature of the air layer under the clothing and to ensure a constant and comfortable micro-environment temperature. At the same time, in the process of fire fighting and rescue, firefighters are often faced with open flames and dense smoke, which may lead to the risk of accidentally falling or falling from a high altitude. Moreover, during the rescue process (especially high-altitude rescue), firefighters will use safety ropes or rescue safety belts. If the flame touches the safety rope or rescue safety belt or the temperature of the environment is too high, there will be safety ropes or rescue safety belts. The fusing of seat belts has caused rescue personnel to fall from high altitudes and caused casualties, which seriously threatens the safety of firefighters themselves. Therefore, the anti-fall performance of firefighters wearing their clothing cannot be ignored. In addition, with the continuous advancement of my country's urbanization process, while people's living conditions have been improved, the height, scale and density of buildings such as residences and shopping malls are also increasing, which makes the danger of fire and the difficulty of rescue greatly increased. , especially the problems of heat stress and falling from heights. To sum up, it can be seen that it is very important to solve the problems of high temperature protection and fall prevention in the work of fire rescue personnel. Therefore, the present invention provides an intelligently regulated safety protective firefighting clothing and its production method to solve the problems of thermal stress in consumer clothing and falling from high altitudes that are easy to fall and fall to death in the above-mentioned background technology.

Contents of the invention

The purpose of the present invention is to provide an intelligent regulation and control safety protection fire-fighting clothing and its production method to solve the problems of thermal stress in consumer clothing and falling from high altitudes that are easy to fall and fall to death in the above-mentioned background technology. A soft elastic stretchable pipe (composed of polyester, aramid, spandex blended fibers) is arranged between the comfort layer and the heat insulation layer. During the fire fighting and rescue process, a soft, elastic and stretchable pipe is arranged between the comfort layer and the heat insulation layer of the firefighting clothing as a heat dissipation water cooling pipe for the flow of cooling water, realizing the thermal perception of the firefighting clothing and intelligently regulating the air layer under the clothing Temperature and ensure the constant and comfortable function of its micro-environment temperature; when accidentally falling, the soft, elastic and stretchable pipe can also be used as an airbag, absorbing and buffering external forces to form a protective effect, so as to protect firefighters from accidental falling injuries.

In order to solve the problem of easy falling and falling to death when falling from a high altitude, the present invention provides the following technical solution: use the MPU9250 integrated inertial sensor to collect the multi-dimensional human body motion posture data of firefighters, and transmit it to the STM32F103VDT microprocessor through the I ² C bus. The processor matches the received signal with the high-altitude fall posture model. If it judges that the current action posture belongs to the category of falling danger, its microprocessor will activate the miniature high-pressure gas cylinder and complete the inflation of the retractable airbag within 50ms to ensure accidental fall The soft, elastic and stretchable airbag can absorb and buffer external force to form a protective effect, so as to protect firefighters from accidental fall injuries. And start the safety alarm module at the same time, that is, the TMB12A buzzer continues to alarm and the LED light continues to flash, so as to inform the surrounding personnel and the police to take immediate action to rescue the falling high-altitude firefighters. In addition, in order to maximize the protection of the personal safety of firefighters when they fall from high altitudes in different emergencies. The air bag opening mode of the present invention also increases the manual opening mode. That is, the airbag activation mode of the present invention is divided into a manual activation mode and an automatic activation mode, wherein the manual activation mode: the staff can manually open the air bag according to the actual emergency situation; When falling, a control command will be issued, and the airbag will be opened by the controller. The above two working modes for starting the airbag can work independently and complement each other. For the manual start mode, set the highest priority for opening the airbags for the smart safety fire suit. At this time, no matter whether a high-altitude fall occurs or not, the wearer can trigger the airbag to work by pulling the device, which enhances the protection. When firefighters accidentally fall from high altitude, if their hands are occupied at this time, they cannot manually open the protective device. At this time, the automatic start mode will be started, that is, the multi-dimensional human motion posture data of firefighters will be collected with the help of the MPU9250 integrated inertial sensor, and transmitted to the STM32F103VDT microprocessor through the I ² C bus, and the microprocessor will receive the signal and the high-altitude The falling posture model is matched. If the current action posture is judged to be in the dangerous category of falling, its microprocessor will activate the miniature high-pressure gas cylinder to complete the inflation of the retractable airbag within 50ms, ensuring that the soft, elastic and retractable airbag will be inflated in case of an accidental fall. It can absorb and buffer external forces to form a protective effect, so as to protect firefighters from accidental fall injuries. And start the safety alarm module at the same time, that is, the TMB12A buzzer continues to alarm and the LED light continues to flash, so as to inform the surrounding personnel and the police to take immediate action to rescue the falling high-altitude firefighters.
