Greenhouse construction has been developing with a fast speed in China, up to now, both the amount and the size of greenhouses are leading in the world. In recent years, a variety of large-scale intelligent greenhouses are emerging. Their functions cover scientific research, education, science transmission, exhibition, tourism, leisure and entertainment, etc. Moreover, their shapes include triangular, cylindrical, rectangular shapes, etc. The size of greenhouse has increased sharply from hundreds to hundreds thousands of square meters, so far, The greenhouse of Tianjin Binhai International Park is the largest domestic single building whose area reaches as large as three hundred thousand square meters. However there exists a large number of problems in the field of greenhouse building, in particular the construction of electrical engineering systems. One typical problem is lack of uniform norms and standards. As a consequence, when constructing the norms and standards of greenhouse, people have to refer to the relevant norms and standards of civil or industrial buildings.In this paper, first of all, we briefly introduced the basic concepts and characteristics of intelligent greenhouse. Then, in accordance with the civil, industrial building design standards. each electrical engineering system of intelligent greenhouse was analyzed and summarized respectively, including electric power supply system, lighting system, lightning protection system, generic cabling system, automatic fire alarm system, security and protection system, and the automatic control system. Finally, we pointed out the drawbacks of the current norms and standards as well as proposed our recommendations for future improvement.Then we practiced our theory in the project of Multi-span greenhouse gardening industrialized breeding center of Henan Provincial Academy of Agricultural Sciences, modern agricultural science and technology experiments and demonstrations base. In this project, we studied the electrical design in term of the power supply systems, power and lighting distribution systems, lightning protection and grounding systems, etc.Collectively, our electrical design and research of intelligent greenhouse scarified the running of this center. And according to this program, we came up with a systematical set of intelligent greenhouse electrical design and technical specifications or measures, in particular for the large townhouses smart electrical design of the greenhouse.This study by the intelligent greenhouse electrical design content to summarize and analyze research, I hope to attract the attention of the industry authorities and industry insiders greenhouse Electrical Engineering, to promote the healthy development of the greenhouse industry.
