this year marks the 75th anniversary of the founding of the people's republic of china and is a critical year for achieving the goals and tasks of the 14th five-year plan. as a new round of scientific and technological revolution and industrial transformation forms a historic intersection with china's accelerated transformation of its economic development model, the development of new quality productivity has become an important measure to consolidate the material and technological foundation for the comprehensive construction of a modern socialist country, and it is an inevitable trend.
those who observe the trend are wise, those who analyze the trend are intelligent, and those who follow the trend will succeed. based in the guangdong-hong kong-macao greater bay area, we will go to key cities covered by major regional strategies to find the shining highlights of china's technological innovation and industrial innovation, and start the third season of the in-depth investigation of digitalization of enterprises in the guangdong-hong kong-macao greater bay area. from may to august this year, yangcheng evening news will join hands with many media outlets across the country to carry out the national tour of new quality productivity. through in-depth research and reporting, we will present to readers the "renewed" picture of new quality productivity with a surge in technological innovation, a rise in industrial iteration, and a surging momentum of digitalization.
in nanjing, an engineering consulting and design group is moving from infrastructure to emerging professional fields such as intelligence, environmental protection, new energy, prefabricated construction, and commercial consumption. it has also compiled the first "nanjing city low-altitude flight-suitable airspace schematic diagram" and "nanjing city low-altitude route demand schematic diagram". yangcheng evening news and yangtze evening news visited huashe design group co., ltd. to jointly explore the development "offensive" of nanjing's new quality productivity.
traffic design is more "smart": generate new solutions with one click
"we started the restructuring in 2005, from a public institution to a company with all employees holding shares. before the restructuring, we were only involved in the two fields of highway and water transportation. after the restructuring, we started to engage in comprehensive transportation, such as aviation and environmental protection." deng runfei, chief planner and director of the board office of huashe group, said. in the exhibition hall of huashe group, more than 7,000 kilometers of highways, 80 airport project consulting and design, 3,200 kilometers of inland rivers and coastal waterways above level 4 are displayed.
the interactive integration of real and digital transportation has always been the focus of huashe group. "our independently developed cad/bim graphics computing engine version 1.0 can quickly build digital 3d terrain and realize 3d visualization parameterization and intelligent design of transportation infrastructure." deng runfei explained the software operation in the video. in the 3d picture of the traffic route construction, the design efficiency is increased by 10 times through dynamic update and control points.
"for example, if you modify the width and diameter of this bridge, the software will automatically generate a new bridge layout." in deng runfei's view, this self-developed technology has changed the previously used 2d cad design method, realized 3d linkage design, and transformed the design and drawing process into a 3d construction process. in addition, huashe group also uses vr technology to simulate real road traffic conditions to evaluate the safety, efficiency and feasibility of traffic design solutions.
"in the digital virtual world, the system can not only collect real-time data on multiple types of driving behaviors, including speed, acceleration, posture, steering wheel, lateral deviation formed by turning pedals, etc., but also simulate various complex road conditions and traffic conditions, such as rush hour, emergencies, traffic accidents, etc., so as to evaluate the performance of traffic design schemes under different circumstances." deng runfei said that in this way, designers and decision makers can better understand the advantages and disadvantages of road design schemes and room for improvement.
"we use digital means to solve engineering safety problems. we basically use products from germany and japan. this may be the first domestically developed product. currently, our largest sales are to universities, especially those with transportation majors."
low-altitude economy flies high: flyable airspace expands again
the airport design consulting service is an opportunity for china construction group to enter the low-altitude economy.
"in the early days, we were designing general airports in jiangsu and anhui. although there are differences between low-altitude economy and general aviation, that was equivalent to the beginning of our formal involvement and familiarity with the aviation field." deng runfei introduced that the design of general airports (airfields, including runways, air traffic control, communications, monitoring, etc.) is an area where china construction bank is very good at. "for all aircraft, if you want to fly, new infrastructure such as ground take-off and landing points and passages are necessary."
low-altitude economy starts with infrastructure construction. in april this year, the "taicang civilian uav test flight operation base construction and service project" led by huashe group passed the expert group acceptance of the civil aviation administration of east china. the base is the first civil uav test flight operation base in suzhou and the second in the province. in addition, digital air transportation, low-altitude internet of things, plant protection testing, etc. are also the focus of huashe group.
"like a flight service station, it has to do ground navigation, ground surveillance, ground monitoring and other work. we have participated in the construction of a local base in suzhou." deng runfei said that in terms of low-altitude internet of things, the base's aerial vehicles have achieved 5g communication navigation below 300 meters, "which is actually very similar to the internet of vehicles." in jiangbei new district, drones are connected to the logistics distribution system of yangtze river shipping ships, solving the problem of the "last mile" of water delivery.
how can the low-altitude economy move from a hot concept and policy to a hot market? "unmanned manned aircraft between cities and within cities can theoretically fly from office building to office building, but if they want to operate normally, they need to approve take-off and landing points, and they also need to solve the problems of noise and endurance. some problems cannot be solved in a short time," deng runfei said, giving an example.
in deng runfei's view, how to gradually expand the airspace pilot will be the focus of huashe group. the first "nanjing low-altitude suitable airspace schematic diagram" and "nanjing low-altitude route demand diagram" compiled by huashe group mentioned that the suitable airspace area below 120 meters in nanjing is about 1,670 square kilometers, and 20 temporary airspaces have been approved, with a total area of 944.35 square kilometers; at the same time, the approved routes have increased to 102, with a total mileage of 1,236 kilometers.
it is worth noting that the "three-year action plan for the construction of low-altitude flight service guarantee system in nanjing (2024-2026)" prepared by huashe group was also officially released recently. the "blueprint" drawn up in the "action plan" also responds to this demand, proposing to strive to set up more than 1,500 square kilometers of airspace by 2026, and expand the flyable airspace from below 120 meters true altitude to below 600 meters.
