Zhongguancun Forum | Dynaflow successfully selected for the "Top 100 New Technologies and New Products List" of the Zhongguancun International Technology Fair

On April 25th, the Zhongguancun International Technology Fair, hosted by the Beijing Municipal Science and Technology Commission and the Zhongguancun Management Committee, was successfully held, and the "List of 100 New Technologies and New Products" was released. Four projects from companies in the park were successfully selected: Dynaflow "Simulated Microgravity Device", Tonghao Communication Information Group's "Key Technology for Multi-modal Omni-directional Perception of Abnormal Events in Complex Environments of High-speed Railways", Jiaokong Technology's "Intelligent Train Dispatching and Command System for Urban Rail Transit", and Changzheng Medical's "Huisheng-I ECMO". This reflects Fengtai's technological leadership in high-end medical devices, information security, intelligent manufacturing, and high-end equipment.

This year's list aims to showcase a batch of world-leading original scientific and technological achievements, promote the transformation of these achievements into market applications and real productivity, strengthen the effectiveness of building an international science and technology innovation center, and further improve the global technology trading ecosystem of Zhongguancun. Selected projects will receive supporting services such as project roadshow promotion, supply and demand matching, platform promotion, investment and financing matching, registration and landing, and science and technology policy consultation.

List of 100 New Technologies and New Products

Project

Dynaflow——Simulated Microgravity Device

This project uses digital control technology. By randomly changing the direction of the gravity vector during three-dimensional (3D) movement, it makes the gravity acting on the object almost entirely used to offset inertial force or centrifugal force, that is, the gravity is entirely used to provide the acceleration required for the object's movement, thereby eliminating the influence of gravity and achieving ground-based simulation experiments of microgravity. In terms of the algorithm for the movement trajectory, the software simulates the movement trajectory of the sample under test and calculates the coverage rate of the movement trajectory, while optimizing the theoretical speed setting range; from the functional design, it fully considers the application needs of scientific research instruments, and has completed experimental matching with multiple research fields, and can adapt to changes that may occur in its needs in the near and distant future. This product has already carried out preliminary cooperation with dozens of universities and research institutes, including silkworm cultivation, soybean cultivation, stem cell cultivation, lipase hydrolysis, brewer's yeast cultivation, suspension cell cultivation, osteoblast cultivation, protein induction, etc. Compared with the experimental results under normal gravity and microgravity environments, there are significant differences. The microgravity device can be widely used in cell cultivation and related experiments and scientific research work in the biomedicine field.

Tonghao Communication Information Group——Key Technology for Multi-modal Omni-directional Perception of Abnormal Events in Complex Environments of High-speed Railways

This project comprehensively utilizes multi-modal methods such as video analysis and radar monitoring. It innovatively integrates various deep learning algorithms such as target detection, semantic segmentation, and difference detection. Based on cutting-edge technologies such as flexible projection and segmented encoding and decoding, it achieves deep alignment and fusion analysis of feature information in video images, video encoding, and radar echoes. At the same time, it is supplemented by engineering technologies such as hardware acceleration, small sample training, and multi-dimensional stereoscopic visualization. It performs omni-directional perception, intelligent analysis, and real-time alarm on normally operating trains, as well as personnel intrusion, equipment abnormalities, and disasters such as falling rocks and debris flows that may threaten train safety, effectively ensuring the safe operation of rail transit. The system has been deployed and applied on multiple lines such as the Beijing-Zhangjiakou High-speed Railway, the Beijing-Tianjin Intercity Railway, and the Beijing-Shanghai High-speed Railway, and is also applied to the subway and smart city industries. It has promoted the innovation of communication and information technology in the field of rail transit and smart cities, improved the intelligent operation level of rail transit, and contributed to the in-depth reform of rail transit and the construction of smart cities.

Jiaokong Technology——Intelligent Train Dispatching and Command System for Urban Rail Transit

This project effectively solves the problems of incomplete information acquisition, low professional coupling, weak coordination between main and branch lines, and difficulties in manual emergency handling without system support in the existing operation process, from aspects such as train information acquisition, situational awareness, auxiliary decision-making, and strategy execution. The system has overcome key technologies such as automatic timetable compilation based on capacity and volume matching, generation of dispatching strategies for emergency scenarios, dynamic adjustment of timetables based on maximum capacity, and automatic arrangement of dispatching commands based on scenarios. The product is at the leading level in the industry in terms of product concept and functional design, especially in the field of rail transit train dispatching and control. It is the first in China to achieve online real-time dynamic adjustment of urban rail transit operation plans. It has completed on-site verification on Beijing Subway Line 19 in scenarios such as points failure, extended operation, and large passenger flow.

Changzheng Medical——Huisheng-I ECMO

This project is the first "purely domestic" ECMO designed, produced, and tested in China. It has completely independent intellectual property rights and its overall performance and indicators have reached the level of international counterparts. It is suitable for adult patients with acute respiratory failure and other treatment methods that are difficult to control and have a foreseeable risk of continued deterioration or death. The Huisheng-I device is highly stable, uses motor control drive technology of aerospace servo systems, can precisely control the speed, and reduces the perfusion fluctuation caused by changes in human blood load; it has high integration, with a total weight of about 7.5kg, which is 1/2-1/3 the weight of similar foreign products; it is easy to operate, with a simple process, and all functional settings can be completed within 2 steps. As one of the five major scientific and technological achievements for people's health, it was released at the 2023 Zhongguancun Forum and included in the "Beijing's First (Set) Major Technological Equipment Catalog" and selected into the "Ninth Batch of Excellent Domestic Medical Equipment Product Catalog" of the National Health Commission.
