When it comes to "Beidou", everyone will be familiar with it.
Since ancient times, it has been an important sign to indicate the direction. If you get lost, you will find the Big Dipper, which is the experience passed down from generation to generation by Chinese.
Today, it is the most important weapon of the country that shines in the sky. Although it is often difficult for us to see with the naked eye, we can enjoy this crystallization of contemporary Chinese wisdom on our mobile phones at any time.
Since the beginning of this year, China's Beidou industry has continued to maintain rapid growth, the scale of application has been expanding, and the depth of application has continued to increase. **Enterprises are an important force in the application and development of Beidou system. In recent years, the company has accelerated technological research and product innovation, launched a number of marketable Beidou products and solutions, and handed over a heavy "report card" for promoting the development of Beidou industry.
Beidou, the "navigator" of a better life
The local old driver went around in a circle, and his brother dared to walk only when he led the way. In Chongqing, the "magic capital", the roads are bent and sloping, the buildings are "dreamy", and travel is often difficult for local residents and tourists. However, in the Chongqing Liberation Monument Underground Ring Road, which is composed of "one ring, seven connections, and N connections", drivers can travel without worry. Why is that?
Liberation Monument underground ring road plan, three-dimensional map.
"5G + Beidou" is the "golden key" of smooth travel. In order to solve the travel problem,China MobileRelying on the world's largest, most extensive coverage and the latest 5G+ Beidou high-precision positioning system built by itself, the 5G+ Beidou precision navigation project of Chongqing Jiefangbei Underground Ring Road has been built to provide accurate positioning and navigation services that are completely consistent with the ground for the majority of drivers and passengers. This is also the first time in the industry to realize seamless positioning and navigation between indoor and outdoor Beidou in the tunnel scene.
Indoor navigation is the "last mile" of navigation technology. When you walk into an unfamiliar stadium and can't find your destination after the signs, do you ever think, "If only you could navigate indoors?" During the 2022 Winter Olympics, such expectations became a reality in "Snow Ruyi".
The National Ski Jumping Center is built on the mountain, like a "Ruyi" located between the valleys, hence the name "Snow Ruyi". Its building has a high degree of three-dimensionality, many indoor space distribution, and it is difficult for satellite navigation signals to enter the venue and underground area.
The "black technology" that solves the problem is the reasonElectrical BranchThe Beidou micro base station indoor high-precision navigation and positioning system developed by Netcom. Beidou micro base station is the first small Beidou indoor sub-meter positioning base station independently developed in China, which can realize rapid positioning in the whole venue area according to the characteristics of building structures in different indoor environments, and the static positioning is better than 01 meter, dynamic positioning is better than 05 meters. "Xue Ruyi" is also the first large-scale stadium in the world that can achieve large-scale indoor and outdoor sub-meter continuous positioning.
During the Winter Olympics, byChina Central Inspection & Prosecution Co., LtdThe gas pipeline network detection project based on Beidou's accurate spatio-temporal information was developed, and the gas leakage inspection work was successfully completed to ensure the safety of the event. These scientific and technological achievements are the precious wealth of the Winter Olympics, and can also be widely used in densely populated areas such as airports, high-speed rail stations, and residential areas, becoming a "booster" for people's better life.
Beidou, the "accelerator" of industrial transformationBeidou brings us more than just navigation. In recent years, "Beidou+" and "+Beidou" have been widely used in the energy, power, infrastructure and other fields of central enterprises, helping all walks of life to accelerate digital and intelligent transformation, forming a good situation of in-depth application and large-scale development.
Nowadays, when you walk into many mining areas in our country, you will see a scene of "no man's land": mining trucks are busy working, and some cabs are empty. This is not a picture of a science fiction movie, but a microcosm of Beidou's empowerment of the coal industry to become intelligent.
InHuanengRelying on the high-precision spatial positioning and sensing technology of the Beidou navigation system, Yimin open-pit mine has realized multi-scenario applications such as unmanned pure electric mining truck loading and unloading operations, real-time monitoring and early warning of pit slope displacement, and collection and analysis of positioning data. At present, the production test of 9 unmanned pure electric mining trucks has been completed, which can achieve "truly unmanned" operation and all-weather uninterrupted operation.
Railway transportation is the most important mode of transportation of coal in ChinaChina General NumberThe "Train Autonomous Operation Control System Based on Beidou Positioning" developed for freight railways will soon be put into use on the Pingmei Railway. After the application of the system, it will effectively shorten the train departure interval, greatly improve the capacity of the district to receive trains, depart and pass, and promote the further increase of the line.
In the field of building construction, the application of the Beidou system is in full swing. Chinese architectureSelf-developed IABM intelligent assembly bridge making machine 20, its Beidou navigation and positioning system can realize the automatic hoisting control of prefabricated components, and increase the efficiency of the installation process by more than 20%;China RailwayThe world's first pile-beam integrated intelligent bridge erecting machine "Gonggong" developed by using the Beidou positioning system to drive piles, realize a full set of "air" operations for pilot holes, piling, beam erection, and assembly of bridge piers, and complete the erection of the first bridge in the "career" in November this yearChina Railway ConstructionIn cooperation with Wuhan University, the "Beidou Inertial Navigation Car" was independently developed, which was successfully applied to the construction site of the Chaoyang hub to Shunyi section of the Beijing-Shenyang high-speed railway, and completed the multi-round precision measurement task of nearly 50 kilometers of ballasted track, which is also the first engineering application of the Beidou-3 global satellite navigation system in the field of high-speed rail construction.
On November 28, the Shenzhong Passage Submarine Tunnel was fully completed, with an immersed tube section of 5,025 meters long, and each standard immersed pipe section is 165 meters long, 46 meters wide and 10 meters high6 meters, the displacement is equivalent to a medium aircraft carrier. How can such a behemoth complete millimeter-level docking at the deepest depth of 40 meters?Beidou is the super intelligence behind the super project.
When the project was launched, it coincided with the commissioning of the Beidou systemCCCGFor the first time in the world, the Beidou satellite positioning system was introduced into the field of immersed tube construction, and the Beidou satellite antenna on the ship and the nearby reference base station cooperated to carry out differential positioning of the immersed tube, with an accuracy of up to millimeter, and created a "deep precision" of millimeter-level docking of 7 consecutive pipe sections, which far exceeded the error of 5 cm required by the design.
Beidou, rescue and rescueIn February this year, a news that "the donkey friend Gongger grassland got lost in heavy snow, relied on mobile phone satellite communication to send a distress signal, and was finally successfully rescued", which attracted a lot of people's attention. The key to being rescued is built into the traveler's mobile phone, byChina Electronics Technology, Ordnance Industry Group, China Mobilemovingand other joint research and development of the first domestic smart phone Beidou short message communication RF baseband integrated chip.
At present, the Beidou system has played an important role in rescue and rescue at home and abroad. The addition of Beidou has significantly improved the efficiency of rescue and rescue.
In July 2021, Henan Province was hit by a historically rare heavy rainstorm and severe flooding. In order to avoid the accident of falling tower and disconnection, Anyang Power Grid has urgently deployed 25 sets of power Beidou tower tilt monitoring terminals in the flood discharge area to monitor the situation of the affected towers in real time. At the same time,State GridOn July 28, 2021, the platform responded to 13,872 requests for high-precision positioning services in a single day, helping Henan to successfully complete the rescue and power protection.
State Grid employees install power Beidou tower tilt monitoring terminals for towers in flood discharge areas.
When fishermen go out to sea, they are most afraid of bad weather. In August of this year,China TelecomMore than 3,000 fishing boats in Fuzhou are equipped with Beidou-3 shipborne positioning terminals, so that key data such as battery power, tilt status, and navigation status of ship equipment can be uploaded to the Lianjiang Smart Maritime Integrated Management Platform in real time through the Internet of Things, weaving a huge "safety net" for marine rescue.
Above the Yellow SeaChinese green hairJiangsu Rudong Offshore Wind Farm is the first wind farm in China based on Beidou positioning personnel tracking and overboard auxiliary rescue system. The station is equipped with 20 Beidou mobile companions, which can not only send out distress information with one click in case of failure or distress, but also view the location information of other people going to sea, which is convenient for mutual cooperation and resource allocation, and effectively solves the problem of personnel safety control and rescue caused by the limited network coverage around the offshore wind farm.
In the face of hidden, sudden and destructive geological disasters, how to give early warning and prevent problems before they happen, Beidou is also giving the answer.
Maintaining dam safety is the focus of the daily work of hydropower plants. In view of the complex environment of the surrounding area of the hydropower station and the potential existence of major geological disastersChina HuadianThe comprehensive use of Beidou, satellite remote sensing and other monitoring methods to establish a geological disaster monitoring and early warning system, to achieve the management of the whole process of the evolution of hydropower stations and surrounding geological disaster areas, effectively avoid the economic losses caused by geological disasters, improve the ability of monitoring the safe operation of hydropower dams and the monitoring efficiency of safe operation around hydropower stations.
