How popular is skiing?

Report on Ice and Snow Tourism in China2020It shows that the number of ice and snow travelers in a single ice and snow season in China exceeds for the first time. 2 The goal of "300 million people on ice and snow" set by the State General Administration of Sports suddenly approached.

Summer has arrived, and indoor ski resorts are still hard to get.……

While enthusiasts flock to the ski resort, the hidden safety problems also begin.

2021 A year, a year 1 The moon, the moon 4 An accident occurred at Chongliyun Peak Ski Resort in Zhangjiakou City, Hebei Province. A man tripped over an electric juggernaut while skiing and died. Since then, local sports departments have required ski resorts to conduct self-inspection and carry out persistent inspection. The safety inspection and rescue system in the ski resort is negative, which has become the main direction of inspection.

In this regard, established European ski resorts with mature patrol and emergency rescue systems Val Thorens（Val Sorens, Val Sorens）What is not worth mentioning is the rental and appraisal of ski resorts around the country. Especially in recent years.Val Thorens The use of drones for daily inspection and rescue work shows good results.

In a recent avalanche, the patrol of the ski resort successfully rescued the first skier with drones, thus the corporal of the patrol and theDJI UAVIt became very popular in the ski circle.

DJI drones become "members" of patrol teams.

Val Thorens The ski resort is built in the valleys of the French Alps, with ultra-high altitude backrest and winding slides.Val Thorens It has been rated as "the best ski resort in the world" for many times. Compared with domestic ski resorts, high altitudeVal Thorens More prone to avalanches-cutoff 2020 The avalanche here occurred. 15 Next one

Even so Val Thorens The staff of the ski patrol are too much. 200 People, however, as a large ski resort, the burden of maintaining infrastructure and helping skiers in difficulty is still heavy.

2019 In 2008, a new member of the ski patrol came-- drones. After fully investigating the feasibility of the UAV patrol logic scheme, the ski patrol began to use the DJI flight platform with zoom, infrared and other lenses to participate in the work.

The application of UAV in ski resorts is widely praised, which not only saves time and cost, but also can better protect the life and safety of team members.2019 Before the winter of 2008, the team of drones at the ski resort was officially established.

Three major uses, patrol inspection is more comprehensive

Inspection is the daily work of the ski patrol. The new member of UAV provides an efficient and convenient way to patrol the snow.

1.Slope reconnaissance and safety assessment

Usually, before declaring the trails safe and open to skiers, patrols must manually inspect the complete trails, which are time-consuming and dangerous.

With drones, the patrol team can first use drones to detect snow trails in advance and accurately locate the area out of danger. Slope assessment work is more effective and safer from here.

The patrol's focus extends far beyond ski resorts. In the area outside the ski resort, the cruise team also needs to identify which areas have too many snowdrifts and take targeted measures to prevent avalanches. Unmanned work can replace the patrol team to find these areas quickly, which greatly reduces the safety risk of customs personnel.

2.Check the snow resort infrastructure

The infrastructure of ski resorts, such as ski cars, trams, communication structures, safety equipment, etc., are often exposed to extreme weather, and the task of inspection is extremely heavy. With drones, inspectors no longer have to check closely one by one. Through the drone screen to find the need for maintenance, and then send someone to overhaul.

Gas explosion avalanche control equipment is the most important snow field equipment.Val Thorens The valley where the snow resort is located has 101 A device like this. It turns out that inspection has always relied on experts to fly by helicopter, and that it has always relied on expert towers. If you determine the requirements for maintenance, you also have to bring the appropriate materials and tools to the site by helicopter again.

After the introduction of Dajiang UAV, the zoom and thermal imaging lens carried by the UAV make remote "consultation" possible, and even provide important information invisible to the naked eye, which greatly saves the daily inspection cost of the ski patrol team.

3.Night patrol inspection

The ability to work at night is a big advantage of drone patrols. Dajiang drones can fly at night, of course, in the air or on the ground, you can see the position of the drones by night lights to ensure the safety of personnel and flight. Fuselage integrated ADS-B The receiver can use the location of the nearby aircraft to give warning to the driver.

The night inspection of the UAV can accurately locate the areas requiring trimming and artificial snow, and guide the ground personnel to quickly complete the inspection and repair of the ski slopes before the ski resorts open in the morning.

Extremely fast search and rescue, saving 50% Rescue time:

1.Aerial search and rescue

On wide ski resorts, drones provide valuable aerial views, of course, through thermal signals that show skiers one night in the forest and fog, accurately locate mazes or skiers in danger, and guide searchers to quickly cross obstacles and find skiers.

The drone, coupled with a shouting system, can provide life-saving guidance to skiers in need of assistance and communicate with those in need and time, so as to enhance their confidence in survival.

2.To act quickly; act quickly.

Generally speaking, avalanche victims can only survive under snow 20 Minutes, average demand for ski patrols10It takes five minutes to get to the scene. The UAV can bypass the obstacles, fly directly to the avalanche area, and quickly find the victim through zoom and infrared lens, in order to save the rescue. 50% Valuable rescue time.

3.Escort members of the patrol

Every time an avalanche occurs, the patrol must send teams to reconnoitre the avalanche area and look for victims. The mountains and the second avalanche that could occur at any time put the patrol in serious danger. With timely aerial intelligence provided by drones, ski patrols only need police station drones to find victims.

The drones are at the ski resort. Val Thorens（Val Sorens, Val Sorens）The innovative application provides valuable experience for ski resorts all over the country. At present, skiing is accepted and enjoyed by more and more people, and gradually "nationalized".

The application of UAV in ski resorts will help to establish a better daily inspection system and emergency rescue system, and effectively ensure the life safety of skiers.
