Not long ago, the reporter went to the Chagola outpost in the Shigatse Military Sub district for an interview, and the altitude gauge on the vehicle kept rising, while the temperature and air pressure continued to drop. Outside the car window, the strong wind carried gravel and made a crackling sound. After a bumpy journey, the outpost finally appeared in sight. From a distance, a watchtower stands at the top of the mountains. Chaguola, in Tibetan, means "a place where flowers bloom". This post in the Shigatse Military District has the highest altitude, hence it is also known as the "outpost with blooming flowers". However, the outpost has an altitude of 5318 meters, low oxygen content, and an average annual temperature of -10 ℃. Chaguola, Chaguola, reach out and grab the sky; oxygen cannot be fully absorbed, wind and snow often dominate. "This self created oil poem by the soldiers of the outpost expresses the hardships of garrison. Officers and soldiers climb the ice and lie in the snow all year round to guard the border, practicing the resolute oath of "rather let life overdrawn than let mission owe" in the forbidden zone of life. Now, with the care and assistance of leadership at all levels, the appearance of the Chagola outpost has been completely transformed. The former "snow covered island" not only built micro pressure oxygen chambers, connected to water, electricity, and the internet, but also introduced various advanced technological means and equipment, resulting in higher efficiency and stronger border management and control capabilities for officers and soldiers. During the interview, the officers and soldiers of the outpost were on patrol duty. After obtaining approval, the reporter boarded the patrol car and followed the patrol team towards the target location. The vehicle moved forward in the bumpy road, and soon after, a huge glacier stood in front of them. The patrol team changed to walking. This glacier is known as the 'Knife Back' by officers and soldiers. It not only has strong winds and steep slopes, but also has hidden cracks in the ice, making it possible to fall into it with even a slight mistake while walking. The environment ahead is complex, use drones for reconnaissance! ”With the command of the patrol team commander Ren Hongrun, the second level sergeant and drone pilot Xuesong controlled the drone to take off. In the blink of an eye, the drone lightly flew over the glacier valley, and the onboard camera scanned over dangerous rocks and ice ridges everywhere. Real time high-definition images are transmitted, clearly outlining the entire terrain. Based on these images, Ren Hongrun led the officers and soldiers to quickly plan the best patrol route. Border patrols have no blind spots, and 'the motherland is in my heart' is more concrete. ”When it comes to the convenience that drones bring to patrols, Cedar opened the conversation box. That year, the mountains were covered in heavy snow, and officers and soldiers patrolled and performed their duties in the snow. As a pioneer in exploration, he tied a safety rope around his waist and held a pickaxe. He chiseled out his feet inch by inch on the steep ice cliff, and struggled to climb with both hands and feet, just to open up a safe path. Ice shards splattered and stung the face like needles. Such dangerous experiences were common during periods of heavy snow and mountain closures in the past. In the past, when patrolling, only the task of identifying the passage required unimaginable hardship. Nowadays, by manipulating drones into the air, it is possible to quickly determine the condition of glacier roads and scientifically plan patrol routes. ”Xuesong told reporters that in the past, during patrols, officers and soldiers often set out before dawn and returned to the team in the dark at night; Nowadays, with the help of technology, patrol time has been significantly shortened and duty efficiency has been significantly improved. Returning from patrol, the reporter walked into the monitoring room. The monitor displays real-time footage of the border defense line, and despite the howling wind outside the window, the image on the screen is still very clear. Sergeant Wan Duzheng, who is responsible for the duty task, is fully focused on the screen. He introduced to the reporter, "In the past, we mainly relied on telescopes to observe the situation on the front line of border defense. When the mountains were blocked by heavy snow, the observation effect was not good." "With this surveillance system, our efficiency and accuracy in standing guard and duty have been improved. ”Wan Du said that this system can also automatically identify abnormal moving targets within the preset area, issue alerts in the first time, and buy valuable time for dealing with special situations. At the beginning of the installation of many unmanned devices, people were worried that the high-altitude and cold environment would affect their performance? It has been proven that these devices have withstood the test. ”Wan Du told reporters. During the interview, the reporter learned that the outpost is equipped with various unmanned and intelligent surveillance devices, including a multifunctional fusion telescope and a fixed high-definition intelligent camera. These devices are like "intelligent sentinels", on duty 24 hours a day, sharing information in real-time, and building a three-dimensional monitoring network covering key mountain pass channels, making the long border more "transparent" and greatly improving the accuracy and timeliness of information collection. Recently, a private on duty discovered suspicious moving "black spots" at Yamaguchi. At that time, it was in the afternoon, with strong winds at Yamaguchi and sandstorms, and the telescope's field of view was limited. Black spots appear and disappear, making it difficult for officers and soldiers to accurately assess the situation. At a critical moment, Cedar piloted the drone into the sky and quickly flew towards the special situation area. Through the drone returning the footage, the officers and soldiers finally saw clearly that several yaks were foraging at the mountain pass. In the past, when encountering similar suspicious situations, we had to send a reconnaissance team to conduct on-site inspections. The terrain of Yamaguchi is complex, and it takes at least two to three hours to travel back and forth. The soldiers not only consume a lot of physical energy, but are also prone to falling into the air. Nowadays, relying on the three-dimensional monitoring network and cooperating with unmanned aerial vehicle reconnaissance, the verification task can be completed in just a few minutes from discovering anomalies to accurately identifying and approving the situation, saving time, effort, and being precise and efficient. ”Ren Hongrun said. As the new moon rises in the night sky, the sentry post lights up and blends with the twinkling stars in the sky. In the monitoring room, on the screen in front of Wan Du, the monitoring data keeps refreshing; In the equipment room, Ren Hongrun and his comrades are maintaining the drone... The lights on the sentry post are like clusters of burning flames, as if silently confessing: I am at the border, please rest assured for our country and people! (New Society)
