More than 400 experts from management departments, research institutions and industry entrepreneurs gathered in Shenzhen to talk about the development of the UAV industry. "UAV", as a keyword, once again attracted social attention.

Today, by the national security alarm system product quality supervision and inspection center (Beijing), Shenzhen UAV Industry Association sponsored by the "2021 UAV Counterstrike Technology Forum" held in Shenzhen, the forum focused on low altitude security guard, Exchanges were made from four aspects: "New Trends of UAV Countermeasure Technology", "Practical Application Cases of UAV Countermeasure Technology", "Construction of UAV Control Platform" and "Standardization and Testing of UAV Countermeasure Technology". The reporter learned at the scene that in 2020, the total output value of domestic UAV industry has reached 67 billion yuan, with a growth rate of 33%. With the vigorous development of new business forms represented by UAV, low-altitude economy such as general aviation is expected to become a new engine to drive social and economic growth.

In February this year, the Central Committee of the Communist Party of China and the State Council issued the Outline of the National Comprehensive Three-dimensional Transport Network Planning, which clearly proposed to "develop the transportation platform economy, hub economy, channel economy and low-altitude economy" and strengthen the construction of "low-altitude economy" from the national planning level. At present, the reform of low-altitude airspace management is being piloted in Hunan, Hainan and other provinces. Hunan has established the Hunan Low Altitude Airspace Coordinated Operation Management Committee to comprehensively promote the reform pilot work. Hainan takes low-altitude airspace reform as an important part of building an international free trade port. In the General Plan for the Construction of Hainan Free Trade Port, Hainan explicitly mentions "further relaxing airspace control and air route navigation right restrictions, optimizing shipping routes, encouraging the increase of transport capacity and opening more routes and flights". At present, Hainan has successfully built and operated a low-altitude flight control service operation system of "combination of vacant land and three-dimensional support", to ensure that low-altitude flight is "easy to fly, safe to fly and smooth to fly".

So, how to achieve better development of low-altitude economy? Reform of low-altitude airspace management is crucial. "The establishment of a perfect grid-based UAV monitoring and control system will help solve this problem." Jiang Huajing, chairman of Shanghai Tejin Wireless Technology Co., Ltd. (hereinafter referred to as "Shanghai Tejin"), said at the forum that with the development of smart city land and air integrated security system, low-altitude security is bound to develop from the initial focus of the simple defense stage to the all-area low-altitude security control stage. It has expanded from the single function of purely governing "black fly" UAVs to the comprehensive function of comprehensively supervising "cooperative targets" and "non-cooperative targets".

"Like the grid management in grassroots governance and video monitoring system can efficiently complete the ground dynamic information monitoring and effective management, special grade gold TDOA city grid system, and help to fill in the urban management of low-altitude airspace environment dynamic monitoring and control the ability of the blank, meet the demand of urban low-altitude airspace of fine management." "Jiang said.

The reporter understands, as the 70th anniversary of the successful guarantee National Day military parade, the CCTV Spring Festival gala, the activity of oversize low security of unmanned aerial vehicle (uav) control enterprise, Shanghai's gold at the world conference on unmanned aerial vehicle (uav) on the display of "level TDOA city grid unmanned aerial vehicle (uav) control system" will be more connected to the uav detection equipment to build on the basis of grid cell, by adopting the distributed technology, Intelligent switching and seamless integration among the UAV monitoring grids can be realized to break the "information island" and form a low-altitude UAV monitoring network covering the whole city. Once the "Heifei" UAV is found trying to break into the key protection area, the system will quickly deal with the intelligent linkage countermeasure unit to realize the efficient control of the large area of low-altitude airspace. It is understood that the system has been used in a number of key cities across the country. At the end of February this year, Shanghai Tejin and Hainan Jinlin Investment Group Co., Ltd. set up a joint venture "Hainan Jinlin Low-altitude Safety Co., Ltd.", establishing the first enterprise focusing on low-altitude safety technology in Hainan, jointly promoting the construction of Hainan Low-altitude Safety Management Demonstration Zone, and building a low-altitude safety prevention and control system for the general aviation industry. It is worth mentioning that Shanghai T&T launched a new series of hand-held products -- "Portable UAV Detection Equipment" at this conference, which attracted the attention of the industry and won the "Police Equipment Technology Innovation Award". The device is small and light, similar to the shape of a walkie-walkie and weighs only more than 700 grams. It can be used for UAV detection, identification and early warning. The effective detection distance in a complex urban environment is nearly 1 kilometer, and the effective detection distance in an open environment is more than 1.5 kilometers, which can meet the requirements of daily patrol and flexible use.
