China's facility agriculture has high energy consumption, poor environmental control capabilities, high labor intensity, and low resource utilization. The leader of the project, Beijing Jingpeng Global Technology Co., Ltd., gave a technical introduction to increase production. This project integrated innovative energy-saving technologies and developed A series of low-carbon agricultural facilities and equipment, to achieve the efficient use of green and clean energy, and promote the improvement of the atmospheric environment.
Focusing on the use of solar energy for clean energy, the project has integrated technological innovations in the integration of solar photovoltaic power generation technology and solar flat-panel heat-collection technology with greenhouse construction, realized the cogeneration of new energy, and realized the perfect combination of solar energy application and greenhouse construction; Phase change energy storage materials have been innovatively researched and applied in solar greenhouses; they have truly achieved the low carbonization of the annual production of agricultural facilities, and promoted the sustainable and healthy development of agricultural facilities. Developed an electrothermal phase change energy storage device, a solar low temperature phase change thermal storage device , Effectively reduce greenhouse energy consumption.
'The researchers invented a multi-objective optimization algorithm for intelligent control of the greenhouse environment based on the Internet of Things to achieve greenhouse energy-saving control and optimal control of economic benefits.' Zhou Zengchan said that a new-generation greenhouse information acquisition and control system based on the Internet of Things was developed. A group of wireless sensor network nodes and gateways based on ZigBee and 433 wireless communication protocols were proposed. A new algorithm (GOD-MOEA algorithm) for solving high-dimensional multi-objective optimization problems was proposed, and greenhouse environment based on crop physiological characteristics was proposed. Factor coordination control technology, to achieve the precise regulation of the greenhouse environment.
At the same time, the project personnel created a series of plant efficient and safe production technology and equipment to ensure that the crop growth process is safe and pollution-free, providing security for the safe production of vegetables in China.
