  From the Z-20, which was put into rescue and relief missions for the first time, to the aerial lighting of drones, to the satellite transmission system of reconnaissance vehicles...In the front line of flood fighting, innovative technology has become a weapon for army officers and soldiers in rescue and rescue, which has greatly improved the ability of the army to perform tasks. .

  The war eagle roared, piercing the clouds and breaking the fog... At 17:00 on July 22, 33 officers and soldiers of a certain air assault brigade of the 83rd Army took off 3 Zhi-20 helicopters (hereinafter referred to as Zhi-20) and quickly lifted off according to the order of the Central Theater. This time their destination is the flood-fighting front line in Xinxiang, Henan, and their mission is to perform aerial surveys and airdrop rescue supplies.

  This is the first time that Zhi-20 has been engaged in rescue and disaster relief missions.

  From the Z-20 to the aerial lighting of the UAV, to the satellite transmission system of the reconnaissance vehicle... The reporter of Science and Technology Daily found that on the front line of flood fighting, innovative technology has become a weapon for army officers and soldiers in flood fighting and rescue, which has greatly improved the ability of the army to perform tasks.

Zhi-20 participated in the rescue mission for the first time

  "There are people ahead, prepare to lower the altitude." Soon after arriving at the first line of flood fighting in Xinxiang, Henan, Li Zhijiang, the captain of the Zhi-20, spotted the distress signal from the crowd from the roof. He immediately lowered the flight altitude, and after confirming the safety of the airspace, he stabilized the helicopter. Stopped and rescued 12 people from the disaster.

  During this mission, the brigade also used helicopters to carry rescue materials such as drinking water, medicine, and food, and provided assistance to the victims in the form of airdrops and on-the-ground distribution.

Regardless of fatigue, 33 officers and soldiers fought continuously, taking off one after another to carry out flood fighting and rescue missions.

  As the most advanced medium-sized general-purpose helicopter in China, the Zhi-20 has high flexibility and versatility, and is the perfect choice for disaster relief.

  In the past few days, the flood situation in Xinxiang, Henan has been serious, and the dispatch of Zhi-20 is both unexpected and reasonable.

  The Zhi-20 is a medium-sized dual-engine multi-purpose helicopter independently developed by my country. It can perform diversified missions in different regions and has good performance on plains and plateaus. It can be quickly expanded from a basic transportation platform to other missions.

  The information previously disclosed by the Aviation Industry Corporation of China shows that as a new multi-purpose helicopter independently developed by my country, the Z-20 adopts a single rotor with a tail rotor, a low-position rear flat tail configuration, a low-resistance aerodynamic shape, and a high-performance rotor aerodynamic layout. The overall design is equipped with two domestically-made advanced turboshaft engines, and new technologies such as fly-by-wire flight control, rotor anti-icing/deicing, etc., can perform diversified tasks such as air landing and transportation under complex weather conditions day and night. Full-time dispatch ability.

  This trip to Xinxiang, Henan Province, was the first time to participate in rescue and disaster relief missions after the Z-20 troops were installed.

  Military expert Wei Dongxu also stated in an interview with the media that rescuers can obtain more timely and effective on-site information through the Z-20 aerial survey; if some people are isolated in a dangerous area by the flood, the Z-20 can land or hover at a low altitude. They carry out rescue operations and can also provide materials such as water, food, medicine and rescue equipment to the disaster-stricken areas.

  As of press time, the brigade has a total of 4 waves and 70 sorties from Z-20, which lasted 34 hours, covered 17 villages, rescued more than 20,000 people, and delivered 75 tons of materials.

Hard-core "black technology" illuminates the front line of flood fighting

  "Dongyao, Dongyao...report to you on the disaster situation..." On July 22, a heavy rainstorm caused power outages, transmission lines interruption, and optical cable damage to the communication base stations in Zhengzhou urban area. The interruption of communications brought many difficulties to rescue operations. .

  The officers and soldiers of the Reconnaissance Squadron of the Mobile Detachment of the Armed Police Henan Corps used the reconnaissance vehicle satellite transmission system to transmit the rescue scene images to the combat command center in real time, providing a reliable basis for the rescue command’s scientific and precise decision-making, and used the "communication line" to open up the people’s lifeline".

  In addition, UAV lighting equipment, which is more convenient to carry, wider in scope, and more flexible, also played an important role in the rescue.

  A short video full of "technological flavors" went viral on social media.

In the early morning of July 23, at the site of the task of blocking the breach on the dam of the Communist Canal in Xinxiang, Henan, from a distance, under the illumination of a small drone, the soldiers stepped up their actions in the dark to prevent the dam from breaking. What came next was their shouts of "not tired" and "not tired".

On the ground are commanders and fighters fighting continuously, and the sky is a drone that spreads light.

  On July 29, a flash flood occurred in Wangzongdian Village, Cuimiao Town, Xingyang City, Henan Province, and the Operation Support Brigade of the Mobile Detachment of the Armed Police Henan Corps moved out on demand.

As the only professional rescue squadron of the corps, the rescue platoon of the engineering squadron carried professional rescue equipment such as life detectors and snake eye detectors and quickly launched operations. The police dog Carrie, under the guidance of the trainers, conducted meticulous searches in the river.

  The reporter learned that life detectors, snake-eye detectors, etc. are equipment frequently used in disaster relief operations.

For example, the snake eye detector can use light reflection for life detection.

The main body of the instrument is very flexible, like a snake-skin tube used to pass through the sewer, which can twist freely in the rubble.

There is a small probe in the front of the instrument, which can probe deep into tiny gaps, similar to a camera instrument, and can transmit information back. The rescue team can use the observer to see the situation in the depths of the rubble clearly.

  "Since the torrential rain disaster in Zhengzhou, we have moved to five or six fronts. We will go wherever there is danger. This is the duty and mission of the military." said Qin Yuhao, a political instructor of a squadron of the combat support brigade of the mobile detachment on the front line.

Scientific and technological means frequently appear in non-war military operations

  The military has professional advantages in engineering, nuclear, biochemical, and medical technology and equipment, and is an assault force for emergency rescue and disaster relief.

Scientific and technological means are not uncommon in the military's participation in flood fighting and other non-war military operations.

  During the Jiuzhaigou earthquake in 2017, the geological disaster investigation team of the former Armed Police Golden Forces used 3D modeling technology to quickly draw the first geological disaster investigation and evaluation map in the Jiuzhaigou earthquake area, which provided scientific data support for post-disaster reconstruction and prevention of secondary disasters in the earthquake area.

  This set of 3D modeling technology integrates a multi-rotor UAV, a miniature tilting camera platform, a precise positioning system and agile modeling software. It is a space information acquisition technology that has reached the international advanced level.

It can obtain multi-angle image information of the disaster site at one time, and provide ultra-high-resolution field data for automatic modeling.

After the modeling is completed, the technical system can automatically interpret the disaster body, define the boundary and location of the disaster body, and automatically calculate the disaster amount.

This technology can effectively reduce the labor intensity and operational risks of officers and soldiers in conducting emergency surveys of geological disasters, and greatly improve the efficiency of survey work.

  In the flood disaster in the southern region in 2020, the troops in the eastern theater used a variety of scientific and technological methods to improve their operational capabilities and information acquisition capabilities.

These innovative technologies have become a weapon of flood fighting and rescue for military officers and soldiers.

  After entering the flood season last year, the Jiangxi Military Region urgently launched a self-developed intelligent mobilization system to dynamically update the flood disaster information reported daily by more than 18,000 militia information officers distributed throughout the region to improve the decision-making efficiency of command groups at all levels.

In the middle of the night of July 12, 2020, a dike breach occurred in the Triangle Lianwei in Yongxiu County, Jiangxi Province. After discovering the disaster, Yang Dezhi, a militia information officer, published the information in the system as soon as possible. After the commander of the People's Armed Forces Department learned the information, he quickly organized the militia to rescue , More than 20 people were successfully transferred.

  In the Chaisang District of Jiujiang, Jiangxi, a brigade of the 71st Group Army deployed a new type of command cabin at the first time to issue real-time operational instructions to the rescue team in a wartime state.

A relevant person in charge of a brigade of the 71st Group Army said: “Commanding flood resistance is like commanding a war, because you don’t know where new situations will arise. With the help of advanced communication and reconnaissance methods, you can greatly improve command efficiency.”

  A certain pontoon brigade of the Eastern Theater Army, as a "national-level professional flood-fighting and rescue unit", possesses a technical reserve of professional talents and rich practical experience.

During the disaster relief in the flood season in 2020, in response to the problems of low viscosity and easy collapse of the soil in the mission area after continuous soaking, they specially carried several tons of high-viscosity sandy mixed soil for reinforcement and construction of high-risk dams to cope with changes. Strong flood peaks and rainfall challenges.

  "In addition to the application of high technology in improving rescue efficiency, it has also played an important role in ensuring the safety of officers and soldiers." A leader of the Air Force Aviation Division of the Eastern Theater said that unlike the past, the officers and soldiers performing rescue missions are not only wearing life jackets, but also An inflatable life-saving belt that is only 5 cm wide will be worn around the waist.

If someone falls into the water accidentally, just open the inflation valve, and the high-pressure gas in the cylinder will fill the airbag and turn it into a lifebuoy around the waist, adding "new insurance" to the personal safety of officers and soldiers.
