From October 27 to October 31, 2023, final of the 18th “Challenge Cup” National Undergraduate Competition on Extracurricular Academic Science and Technology Works (NUC-EASTW), jointly organized by Central Committee of Chinese Communist Youth League, China Association for Science and Technology, Ministry of Education, Chinese Academy of Social Sciences, All-China Students’ Federation and Guizhou Provincial People’s Government, and hosted by Guizhou University, was held at Guizhou University. SDJU students made several breakthroughs as follows:
In the Special Red Contest of this year’s “Challenge Cup” NUC-EASTW, the SDJU entry “Searching for Third Front Builders and Reviewing the Grand Journey of China’s Industrial Development” by School of Electrical Engineering (SEE) won the third prize.
In NUC-EASTW Black Tech Demo this year, “Airborne Life Detector – UAV Life Detection Radar” by School of Electronics and Information Engineering (SEIE) won the star prize, and SEE’s “Wearable EEG – fNIRS Multi-modal Brain Functional Imaging Cap” won the satellite prize. Another SDJU entry “Design Optimization for Collaborative Operation of 200kV Transformer Substation Indoor Inspection Robots”, guided by SEE Zhang Wei and Zuo Dongsheng was awarded the third prize.
In addition, the other three SEE entries – “Wave & Wind Resistant Digital Twin Empowered Offshore Construction Workboat”, “Missile-borne Aegis - a Leading Miniaturized Anti-interference Navigation Expert” and “Intelligent Reflective Surface Based High-precision Target Perceptual System”, and one SME (School of Mechanical Engineering) entry “Intelligent Tennis Assistant” won the third prizes of Shanghai division.
This year’s “Challenge Cup” NUC-EASTW focuses on the strategy of strengthening science and technology, and aims to improves the effectiveness of education. To continuously improve guidance, influence and credibility of “Challenge Cup”, and to promote its reform and optimization, NUC-EASTW this year followed a “1+1+2 structure”, consisting of the main competition, the open competition, special red contest, and black tech demo. Challenge Cup this year attracted more than 2,000 universities across the country with over 400,000 entries and 2.5 million participating students. A total of 48 universities in Shanghai with 11,406 entries and 76,818 students participated.
No. 1 Prize-winning entry
SEE, “Design Optimization for Collaborative Operation of 200kV Transformer Substation Indoor Inspection Robots”, third prize of NUC-EASTW final, first prize of Shanghai
At present, the continuously expanding smart transformer substations are troubled by issues of traditional manual inspection such as high labor cost, low inspection efficiency, and unexpected safety risks (especially in extreme working conditions). In this regard, the team of SEE graduate students designed and developed an indoor inspection robot for transformer substations. This robot can effectively improve the intelligence and automation of substation inspections, improve efficiency, and ensure the safety of power supply. The robot can operate collaboratively in the indoor inspection of 200kV substation, competent multiple tasks like routine inspection, obstacle avoidance, image collection, and multi-robot collaboration. Characterized by energy saving and high inspection efficiency, this robot can be used in different scenarios of substation inspection as well as other applications.
No. 2 prize-winning entry
SEE, “Searching for Third Front Builders and Reviewing the Grand Journey of China’s Industrial Development”, NUC-EASTW Special Red Contest, third prize.
The SDJU social practice unit started their journey from Shanghai on July 15, and traveled over 9,300 miles within 24 days. Their tight special forces-style search spanned 11 provinces and municipalities across northwest, southwest, northeast, north and central China, and called on 36 third-front builders of the same age as PRC, and visited on site 17 equipment manufacturing companies growing up ever since their establishment during the third front construction period of the last century. The long journey of this social practice well reflected third-front builders’ contribution to China’s industrial development, with vicissitudes of industrial development of the New China recorded via camera lenses and tremendous changes brought by industrial development to economy, society and people’s lives felt by hearts of each social practice members. This stood out not only as vivid exploration of SDJU’s practical education, but also a tribute to all builders of China’s equipment manufacturing industry, an in-depth social investigation around the industrial development and socialist construction of China. During this summer, SDJU social practice unit visited alumni and third front enterprises, excavated and sorted out historical stories and brilliant achievements of some of those SDJU graduates who sacrificed and contributed to China’s equipment manufacturing industry during the third front construction period, which further completed and well proved SDJU’s glorious history of emerging for industry, rising with enterprises and prospering along the way.
No. 3 prizing-winning entry
SEIE, “Airborne Life Detector – UAV Life Detection Radar”, NUC-EASTW star prize .
The entry was a UAV life detection radar, jointly completed by five SEIE graduate students: Yu Feiqiao, Wang Huiyu, Ji Mintong, Meng Zhaohan, and Lu Ying. Compared with similar products on the market, the most outstanding feature of this detector lies in its flexibility in hand operation and mounting to drones or mobile units. and. It is small and flexible, presenting wide applications in different fields. The detector innovatively adopts an independently developed and designed parallel interference cancellation, which can effectively eliminate interference caused by flight vibrations. At the same time, independently developed millimeter wave RF module and antenna module are installed, greatly reducing the detector’s volume and weight, and a guarantee of complete localization of components.
