As the first large-scale comprehensive event of national winter sports held after the Beijing Winter Olympics, the 14th National Winter Games (hereinafter referred to as the "14th Winter") not only benchmarks the Milan Winter Olympics in terms of competition items and competition rules, but also the empowerment of science and technology is also a highlight of this Winter Games.
As the venue for some snow events in the "14th Winter", the Zhalantun competition area has low temperatures, strong winds, low visibility and continuous snowfall on the top of the mountain. In order to better ensure the weather conditions in the competition area, meteorologists have set up weather radars, automatic weather stations, laser wind radars, radiation stations, microwave radiometers and ground-based remote sensing vertical observation systems, which can realize ground-based, space-based and space-based three-dimensional monitoring of time and space at the same time.
At the same time, in order to achieve full coverage of the meteorological monitoring data of the ski resort, the meteorological support personnel of the "14th Winter" comprehensive support group have built 15 sets of meteorological monitoring stations on 6 ski slopes in the ski resort, and set up meteorological monitoring equipment at the beginning, end and key points of the ski slopes. Among them, the millimeter-wave radar of the ground-based remote sensing cabin arrived at the Zhalantun competition area for the first time after the Chengdu Universiade, and it was also the first time to be put into winter sports support.

In the Liangcheng competition area of Ulanqab, the Liangcheng County Public Security Bureau created a safe, orderly, harmonious and stable "ice and snow event" for the "14th Winter" event and tourists through "technology empowerment and smart security".
The Liangcheng County Public Security Bureau makes full use of digital technology empowerment and comprehensively uses visual command technology and information means to build a visual, dynamic and flat point-to-point command and dispatch system "Visual Distributed Agent Management Platform". The platform is connected to more than 900 high-quality probes such as the 350 trillion cluster docking system and the command system of the security headquarters, as well as the face recognition system of the whole area of the competition venue and the hotel where the residence is located, so as to realize the interconnection of the public security network, the Internet and the private network, the command system and the "14th winter" operation command and dispatch center joint commissioning and joint test, real-time comprehensive control of the situation and abnormal behaviors of large-scale activities, rapid response and other functions, and the role of "smart security" is revealed.
In addition, the Liangcheng County Public Security Bureau has set up a "ground patrol team + aerial drone patrol control group", and the ground "foot patrol team" and the drone patrol control group have realized the integrated patrol mode and built an amphibious periphery patrol grid. The three DJI M210 drones equipped with them have improved the air patrol and control force, improved the efficiency of patrol prevention and control, and reduced the pressure on foot patrol personnel. The UAV can reach an average daily flight time of 2 hours, with an average daily takeoff and landing of more than 12 sorties, covering the remote areas and event areas around the ski resort in an all-round way, improving the efficiency of public security prevention and control, ensuring that it can respond quickly in an emergency, providing timely assistance for athletes and tourists, and intelligent cruising adds security weight.
