今年，第十二屆“挑戰杯”中國大學生創業計劃競賽由團中央、教育部、中國科協、全國學聯、黑龍江省人民政府聯合主辦，東北林業大學、共青團黑龍江省委承辦。本屆大賽充分發揮互聯網扁平化動員優勢，以線上為主的形式舉辦全國決賽，超過600萬人次在線參與8項活動。
香港中文大學派出隊伍“朗思科技” 憑 痕量級激光光譜氣體在線傳感平台 贏得
第十二屆“挑戰杯”中國大學生創業計劃競賽 A組：科技創新和未來產業項目 全國決賽金獎。
關於“朗思科技” - 痕量級激光光譜氣體在線傳感平台
在我們賴以生存的大氣環境中，含量不足百萬分之一的痕量級氣體元素，卻時時刻刻影響著企業的生產效率和人類的健康生活。針對來自高污染能源行業的痛點問題和迫切的市場需求，中大工程學院機械與自動化工程學系博士生許可與任偉教授建立了朗思科技這間初創企業，許可博士領導科研團隊設計開發了一套高靈敏度氣體傳感與控制系統，用於電廠煙氣氮氧化物和氨氣分佈式在線監測，提高電廠脫硝能力和效率，實現大氣中氨氣、氮氧化物等汙染的源頭防治。這項發明基於可調諧激光吸收光譜技術以及超高靈敏光聲光譜技術，結合自主研發的自動反饋控制和人工智能算法，並採用先進芯片集成及封裝、無線數據傳輸和快速信號處理等多種技術融合，設計和製造了可滿足氨氮協同實時測量、系統免標定、超高靈敏度(sub-ppm)的氣體傳感系統，代表了香港原創精密儀器科技的最高水平。特別是在這場COVID-19疫情之下，許可博士積極響應本地香港政府的要求，打造了一台測量香港老舊的居民樓室內通風換氣能力的傳感器，用於追蹤病毒氣溶膠分子的流向，目前已經交付使用。朗思的這一系列發明代表中文大學獲得了第12屆“挑戰盃”中國大學生創業計劃競賽全國決賽金獎。
About LaSense Ultra-sensitive Online Gas Sensing System
In the atmospheric environment, trace gas species in sub-ppm level are always affecting the production efficiency and our life quality. PhD student Xu Ke and Professor Ren Wei from the Department of Mechanical and Automation Engineering, the Faculty of Engineering of CUHK, established a startup named LaSense Technology this year, and have designed and developed a series of ultra-sensitive gas sensing and control systems aiming at the urgent market demand from energy industry.
The developed distributed on-line monitoring system based on frontier laser spectroscopy will be used in the denitration process control to improve the denitration capacity and efficiency of the power plant, and to achieve the source prevention of trace air pollution like NH3 and NOx as well. This invention also combines multiple technologies including self-developed automatic feedback control, artificial intelligence algorithm, advanced chip integration, wireless data transmission and rapid signal processing, which represents the highest level of original instrument technology from Hong Kong. During this COVID-19 epidemic, Dr. Xu Ke also lead to build a gas sensor measuring the ventilation capacity of old buildings in Hong Kong, which has been applied to track the flow direction of virus aerosol molecules. LaSense's invention has won many awards this year on behalf of CUHK, including Gold Prize of the 12th "Challenge Cup" National College Student Business Plan Competition.
