In the vast desert, the heat evaporates. On the apron of a certain airport of the Western Theater Command Air Force, hot air wrapped in sand particles rushed towards us. With each breath, the reporter felt a pungent earthy smell, and his eyes involuntarily narrowed into a slit. On the tower, the officials of the department sat in front of the meteorological duty station, closely monitoring the digital changes on the display screen, calmly analyzing data such as temperature, wind direction, wind speed, visibility, etc. In the Air Force, weather is an important factor that must be considered first when organizing flight training. The weather is about to improve, so we can take off as planned. "After the calculation is completed, we will forward our suggestions to the commander. Sure enough, one hour later, the wind stopped, the clouds stopped, and the sand quieted down, and one after another, war eagles roared into the sky. Every summer, there is a significant increase in sandstorms and floating dust weather, which puts higher demands on meteorological monitoring and forecasting. ”Qi Qian told reporters that in response to the complex seasonal weather characteristics of the stationed area, they have collaborated with relevant universities to establish a comprehensive meteorological data database, achieving meteorological information fusion processing, integrated display, and rapid correlation retrieval. The warning time has been significantly advanced compared to the past. The scorching sun hung high, and an outdoor ground equipment was scorching hot, but its interior still operated stably. Qi Qian told reporters that they are keeping up with the cutting-edge technology in the field of meteorology, installing visibility observation instruments, upgrading multiple ground meteorological automatic observation systems, and achieving all-round and full-time monitoring within a range of tens of kilometers around the airport. The increasingly reliable equipment and precise data not only add layers of safety to flight training, but also add confidence and confidence to the work of "weather sentinels". The technological content and precision of flight are both high, and high temperatures may increase the risk of equipment failure, which cannot be underestimated. ”Pointing to the "List of Flight Support Measures under High Temperature Conditions" in front of him, the leader of the department told reporters that each measure not only seeks countermeasures in terms of working methods and techniques, but also seeks breakthroughs in technological means to maximize flight safety. Ensuring airspace safety relies not only on the monitoring and forecasting of "meteorological sentinels", but also on the bird repelling clearance of "field sentinels". During the training break, the reporter saw a small drone patrolling over the airport runway, making sharp noises. Despite being in the hottest period of the day, the drone still works tirelessly under the scorching sun. Summer is the peak season for bird activity, and it is crucial to maintain the runway and clear the airspace to drive away birds. ”The outdoor duty officer told reporters that this is a bird repelling unmanned aerial vehicle from the field operations company, equipped with bird repelling guns, airborne ultrasonic bird repelling devices, and high decibel loudspeakers. It is resistant to high temperatures and sandstorms, and has the characteristics of high-altitude patrol and wide field of view, which can accurately monitor bird conditions in the flight area; Having multiple working modes, it can distinguish different birds and take targeted measures to avoid birds entering the flight area and affecting flight safety. The combination of distant and close observation, the combination of high and low search, and the complementarity of artificial and intelligent are the characteristics of this bird repelling program. During the interview, the reporter found that in addition to bird repelling drones, various types of runway four-wheel drive vehicles, balance vehicles and other equipment also shuttle through the airport during flight intervals, building a three-dimensional bird repelling network and eliminating every blind spot and dead angle above the airport. Previously, technological means were limited, bird repelling efficiency was not high, summer work was hot and tiring, and clothes got wet and dry. Nowadays, we are exploring the formation of a new bird repelling model that combines drones, four-wheel drive vehicles, and manual operations, resulting in doubled work efficiency. ”Zhang Fengli, a soldier driving a four-wheel drive vehicle on the battlefield, told reporters that in recent years, the practical training of the troops has become increasingly tight and the support tasks have continued to increase. However, thanks to the continuous upgrading of technological means, the training and support of officers and soldiers have been orderly and more efficient. With the introduction of technologies such as the "visible light drive bird system" and "pesticide spraying system", the net air quality efficiency of airport bird control has been greatly improved. At the scene of a certain team's security mission, dazzling sunlight poured down. Deng Guangwei, the "security sentry," operated a drone to patrol the perimeter and key areas of the camp that could not be covered by fixed cameras, and analyzed and judged them in real time through the feedback of images. Deng Guangwei introduced that the widespread use of drones not only helps to improve the comprehensive monitoring level of the camp, but also provides assistance for them to deal with special situations. In the past, during summer duty, I had to stand in the sun for two to three hours every day, which was a huge physical test. Now that we are indoors, we can remotely perform duty and maintain long-term vigilance, allowing us to concentrate more on handling unexpected situations. ”Deng Guangwei introduced to reporters that in the past, when encountering special situations, although it was possible to climb to the high ground to observe the whole picture, it was difficult to continuously track distant targets. Now, the flexible and maneuverable advantages of drones have made up for this shortcoming. The new era sentinels, empowered by technology, stand guard for the motherland and the war eagle, including meteorological sentinels, field sentinels, and security sentinels. The leaders of the department told reporters that in recent years, they have also solidly promoted the construction of smart military camps, installed comprehensive information monitoring systems, adopted facial recognition check-in and other methods to weave a secure network, and steadily improved the efficiency of military security management. I will only do one thing in my life, I will be a defender for my country. ”The eye-catching slogan seen by the reporter on the side wall of the government building is a pledge made by the officers and soldiers. Over the past 50 years since the establishment of the military, successive officers and soldiers have rooted themselves in the vast deserts and Gobi, faithfully guarding the "western gateway" of the motherland's airspace, and excellently completing a series of major support tasks.
