On April 23, 2024, the Chinese Society of Environmental Sciences held an appraisal meeting in Changsha for the project results of "Ambient Air Pollutant Multi-parameter Intelligent Monitoring Instrument Equipment and System Application" hosted by Lihe Technology (Hunan) Co., Ltd. After review and questioning by the appraisal committee, it was unanimously agreed that the scientific and technological achievements have reached the international advanced level as a whole, and have reached the international leading level in multi-parameter intelligent monitoring and remote supervision of ambient air pollutants.

The meeting invited 11 experts including Academicians Liu Wenqing, Song Junqiang, and Zhang Yuanhang of the Chinese Academy of Engineering, Senior Engineer Luo Yi of the former Ecological and Environmental Monitoring Department of the Ministry of Ecological and Environmental Protection, Professor Luo Shenglian, Vice President of Hunan University, Professor Zeng Limin of Peking University, Researcher Wang Zifa of the Institute of Atmospheric Physics of the Chinese Academy of Sciences, Researcher Gao Jian of the Chinese Academy of Environmental Sciences, Professor Wang Boguang of Jinan University, Senior Engineer Yu Jianqiao of the Jiangsu Ecological and Environmental Monitoring Center, and Senior Engineer Xie Haitao of the Yunnan Ecological and Environmental Monitoring Center to review and discuss the project results. The meeting specially invited more than ten senior industry experts from the China National Environmental Monitoring Center, the Hunan Provincial Climate Center, and the environmental monitoring centers of various provinces and cities as special guests to evaluate and guide the project. The meeting was chaired by Director Wang Guoqing of the Chinese Society of Environmental Sciences, and Chairman Zou Xiongwei, General Manager Wen Liqun and technical backbones of Lihe Technology (Hunan) Co., Ltd. attended the meeting.

Introduction of equipment and system

The complete set of instruments and equipment for multi-parameter intelligent monitoring of ambient air pollutants is a key milestone in Lihe Technology's independent research and development of gas monitoring. It embodies Lihe Technology's more than ten years of research and development results, involving the independent research and development of more than 10 core sensors. It has developed a domestically produced, highly integrated series of intelligent monitoring instruments and intelligent data management and application platforms covering multiple parameters such as conventional, photochemical components, and particulate matter components. It can realize automatic monitoring of more than 150 indicators, with a localization rate of more than 95%, meeting the needs of intelligent monitoring and intelligent operation and maintenance management in multiple scenarios such as conventional, component, traffic station, cruise monitoring, and emergency support monitoring, forming an urbanized service model based on rapid and accurate monitoring, and has been widely used in the construction and operation of atmospheric pollution component monitoring networks in many places across the country, such as Hunan, Yunnan, Sichuan, and Fujian, realizing accurate monitoring, intelligent operation and maintenance, and online source analysis, solving the needs of relevant departments in intelligent management, data application, and decision-making support, improving the ability of refined control of atmospheric pollution, and achieving significant ecological environmental and economic benefits.

At the end of the meeting, Zou Xiongwei, Chairman of Lihe Technology, expressed his sincere gratitude to all the experts present and promised that the company will seriously study and actively adopt the suggestions of the experts and transform them into practical actions for subsequent research and development and improvement. In the next step, Lihe Technology will continue to adhere to independent innovation and research and development. First, it will continue to make efforts in system intelligence and deeply apply advanced technologies such as AI to intelligent quality control, intelligent operation and maintenance, smart applications, and intelligent prediction of instruments; second, it will carry out in-depth independent research and development of core components such as lasers and Fourier infrared and related instruments, and continue to optimize the performance of components and instruments to create more comprehensive and advanced intelligent monitoring technology and equipment for air pollution.
