With the development of the market economy, urban construction continues to be upgraded and updated, and fire situations continue to become more complicated. Firefighters are dealing with increasingly complex fire situations. Therefore, how to improve firefighters’ personal equipment has become one of the current important research topics.
At present, the personal equipment equipped by domestic firefighting forces generally remains at the technical state of the last century, and the phenomenon that firefighters are repeatedly hindered and trapped in firefighting tasks deserves our deep thinking. The safety of firefighting officers and soldiers is not only related to their life safety, but also of great significance to the country’s military construction and social stability.
The environment at the fire scene is complex, with unpredictable hidden risk factors such as high temperature, heavy smoke, falling objects from buildings, flammable and explosive dangerous goods. Existing firefighting personal equipment products are far from meeting the rescue needs of firefighters and need to rely on Continuous upgrading and improvement of firefighting equipment.
Firefighter personal equipment needs to be upgraded
A fire scene is like a battlefield, so firefighters must achieve all-round protection during fire rescue missions. Their personal equipment includes five categories from head to toe: helmets, respirators, fire suits, fire gloves and fire boots. As far as the current production technology is concerned, no matter what type of equipment is designed and manufactured, all “hardware” factors such as the functionality of the material, the ergonomics of the structural design, and the safety of the color are considered. At the same time, in order to ensure the safety of production quality, relevant standards have been formulated at home and abroad, and technical adjustments have been made with the development of society. The change from old standards to new standards has led to increasingly higher technical requirements for protective products, which also means that awareness of the importance of the quality of firefighting personal equipment is constantly increasing.
But even as our standards continue to improve, there are still a number of issues that need to be addressed with the personal equipment that firefighters are equipped with.
First of all, the complete set of firefighting personal equipment configuration is too heavy. Under normal circumstances, various indicators of the human body’s balance function have troughs around 9.0kg and 11kg. When portable machinery is operating, as the weight of the human body increases, the physical strength and energy consumed by the human body to maintain the weight increase increases, and the human body controls and maintains balance. The ability of the patient decreases accordingly, causing the body to shake more and make it easier to fall.
Secondly, wearing personal protective equipment causes the climate inside the clothes to be stuffy, hot and humid. Experiments have shown that when people wear clothes to maintain optimal comfort, the average temperature of the skin is 33°C, the temperature of the air between the inner layer of the clothes and the skin is about 32°C, and the relative humidity is about 50%. When these conditions are greater or lower than the corresponding values, it will affect the normal performance of human body functions. Firefighters work in a high-temperature environment, and their equipment is relatively closed. The climate inside their clothes is often humid and hot. In addition, they consume a lot of physical energy, so they are prone to symptoms such as dizziness and nausea.
Third, there is a lack of intelligent applicable devices. In a collapsed building filled with smoke, it is difficult to scientifically analyze and judge the environment, avoid injuries from falling objects, and quickly search for victims.
Wearable technology has a bright future
In recent years, wearable technology has become a hot topic in the technology field. In the 1960s, the MIT Media Laboratory proposed wearable technology, which can embed multimedia, sensor and wireless communication technologies into clothing or carry with you, and support gestures, voice and eye movements. operation and other interactive methods. This innovative technology has played a role in the research and development of smart wearable technology. With the advent of the 4G era and the continuous maturity of basic mobile Internet conditions, the application prospects of wearable technology will become even broader.
More common smart wearable products for organizations, such as smart bracelets, can monitor the wearer’s movement status through sensing functions, and can also receive functions such as incoming call reminders on mobile phones through Bluetooth devices.
At present, my country’s wearable device market is still in its infancy, but there is huge room for market growth in the future. As network technology continues to improve, people’s requirements for communication methods and information acquisition continue to increase. The improvement of firefighting personal equipment can also focus on the interconnection and sharing technology of wearable devices and smart terminals, through short-range wireless communication, Bluetooth and other wireless functions, to achieve more convenient information transmission and resource sharing.
Wearable firefighting equipment to be developed
In the future, the smart wearable product market will usher in a development boom, and it will also provide a new direction for the development of personal firefighting equipment.
For example, adding smart terminals to firefighting equipment, through NFC, Wifi, Bluetooth, and other wireless functions, allows the wearer to transmit surrounding information and data at the disaster relief site and share it with wearers in different ranges of search and rescue, and at the same time, it can receive external signals. Output information data. In addition to the interconnection and sharing technology of smart terminals, there are also additions of human-machine interface (voice, somatosensory) and sensing (bone sensing, face recognition, geo-positioning, various sensors) functions.
Just imagine, firefighters wearing personal firefighting equipment with smart wearable technology enter the fire scene, capture the scene environment through infrared imagers, and then share the information with search and rescue vehicles in different ranges through smart terminal interconnection and sharing technology.The information is then passed to the outside staff, who then conduct precise analysis and judgment and feedback it to the firefighters at the fire extinguishing site, so that they can take more accurate actions. At the same time, external staff can use the sensors in the firefighting personal equipment to monitor the wearer’s physical health at all times to avoid injuries to firefighting personnel. Furthermore, building-type fires account for the majority of fires, especially when fighting fires in high-rise buildings. The risk of falling from high-rise buildings often needs to be considered. The development of personal fire-fighting equipment with safe falling devices from high altitudes provides safety guarantees.
The research results illustrate the urgent need to apply smart wearable technology to firefighting personal equipment to solve deficiencies. Through understanding the research results of smart wearable technology at home and abroad, the development of wearable technology has slowly transitioned from the conceptual stage in the past few years to The stage when a product comes out and is tested by consumers also means that wearable technology is gradually moving from concept to reality.
However, there are still some problems in the research field of the application and development of wearable technology for firefighting personal equipment. At present, the production technology of firefighting personal equipment manufacturers and processors is relatively mature, and the requirements for the wearable technology upgrade of the equipment are also relatively strong. However, their research and development capabilities are limited by industry technology. How to develop new smart wearable technology and implement it in the industry? The application of equipment is a difficult problem to be solved.
