Plant Factory Strategic Alliance Established to Accelerate Application in LED Agriculture
On December 5, 2010, the “Plant Factory Innovation Achievement Conference†was held in the lecture hall of the Chinese Academy of Agricultural Sciences. Leaders from the China Finance Office, the Ministry of Science and Technology, the Ministry of Agriculture, etc., Philips, Panasonic, Yiguang, Yangzi, Ou Lin, etc. More than 150 people attended the meeting with well-known enterprises at home and abroad, peer experts and representatives from the press.
At the press conference, Beijing High-tech Enterprise, a high-tech enterprise affiliated to the Chinese Academy of Agricultural Sciences, launched the newly developed home-based plant factory and family gardening products, respectively, with Philips Lighting, and Mitsubishi Chemical of Japan. Dozens of internationally renowned companies such as Panasonic (China) Electrician, Taiwan Everlight, Yangzi Electric, and Ou Lin Group signed a strategic cooperation agreement to innovate in the fields of LED plant lighting, industrial control, air conditioning environmental control, and nutrient solution. The market development and other agreements were reached and a strategic alliance was signed. The convening of the conference not only marked the official birth of the first home-based plant factory in China, but also heralded the formal formation of a strategic alliance for plant plant research and development.
The plant factory is recognized as the most advanced development stage of facility agriculture in the world. It integrates modern technologies such as modern biotechnology, information technology, new materials, mechanical engineering and artificial environment control. The output can reach dozens of times and even hundreds of times in open field cultivation. It can also be produced on non-cultivable land such as Gobi, desert, island, water surface, polar, space and even urban 1f3a skyscrapers. It is considered to be the most effective technical means to solve population, resource and environmental problems in the future. At present, only a few developed countries such as Japan, the United States, and the Netherlands have mastered relevant technologies.
Beijing Zhonghua Yida Facilities Horticulture Technology Co., Ltd. has been committed to the research and development of key technologies in plant factories for many years. After more than 8 years of unremitting efforts, it has successfully mastered the core technical essentials of plant factories and obtained more than 30 national patents. In the year, he also won the second prize of National Science and Technology Progress Award. In recent years, the company has actively promoted the transformation and promotion of innovations in plant factories, and has successively promoted it to more than 10 provinces, municipalities and autonomous regions such as Changchun, Shenyang, Zhuhai, Tai'an, Yangling, Nanjing and Beijing. 2010 Shanghai World Expo, Tokyo Horticultural Exposition, Shenzhen After the high-end exhibitions such as the High-Tech Fair, it has won wide acclaim from all walks of life.
The home version of the plant factory and the family gardening series are all LED lighting, which is more energy-saving and environmentally friendly. It is understood that the Institute of Agricultural Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences has been engaged in the application research of LED in plant seedling plants since 2003. In 2006, it designed and built the first closed LED artificial light plant factory in China and developed it. The corresponding LED light environment control software and light environment control device are provided. In April 2009, the research team also successfully developed the first intelligent plant factory in China, using LED and fluorescent lamps as artificial light sources, and put them into operation in Changchun. At present, Philips, Yiguang, etc. have cooperated with the Academy of Agricultural Sciences on LED lighting in agriculture.
Artificial light has become one of the important means of plant production. The artificial light sources used in the field of plants for many years mainly include high-pressure sodium lamps, fluorescent lamps, metal halide lamps, incandescent lamps, etc. The outstanding disadvantages of these light sources are high energy consumption and high operating costs. Energy costs account for about 50% to 60% of all operating costs. Therefore, improving luminous efficiency and reducing energy consumption has always been an important issue in artificial light lighting applications in the field of plants. According to the statistics of the Ministry of Agriculture, the total area of ​​plant tissue culture in China is over 20 million square meters, and the output value is about 20 billion yuan. With the continuous development of modern agriculture, the demand for agricultural lighting is still expanding, but with the substantial increase in power consumption. As the concept of energy conservation continues to deepen, the huge market opportunities and energy consumption of agricultural lighting pose new challenges to traditional agricultural lighting technology, and provide an excellent opportunity for the development and application of new agricultural lighting.
The characteristics of LED light source and the existing research foundations show that LED as a plant illumination source can be widely used in plant cultivation, greenhouse light supplement, plant tissue culture, plant factories, to promote plant growth, regulate plant morphology, build energy, environmental protection, etc. Multi-faceted advantages, not only can emit light with narrow light, such as red, orange, yellow, green, blue, infrared, etc., and can be arbitrarily combined according to different needs of animals and plants, and it is also a cold light source with low heat characteristics. Proximity of plants and improvement of space utilization can not only provide reasonable light environmental conditions for the growth of agricultural organisms, reduce the use of chemicals such as pesticides and hormones, ensure food safety, but also be a low-energy green light source with broad application. The future is an important development trend of future plant illumination sources.
The cat7 Lan Cable are an eight-core Shield wire. Each pair has a Shield layer (commonly called a Foil Shield), and then a Shield layer (commonly called a Braided screen Shield) outside the eight cores, with the same connection as the RJ-45.The highest transmission frequency of the CAT7 Ethernet Cable S/FTP is 600MHz, and the transmission frequency of the CAT7 Network Cable is 1000MHz.
There are a number of significant differences between the six and seven cabling systems, the most obvious of which is bandwidth.The CAT6 cable of channels provide a comprehensive attenuation to crosspoint ratio of at least 200MHZ and an overall bandwidth of 250MHZ. CAT7 of systems can provide at least 500MHZ of comprehensive attenuation to crosspoking ratio and 600MHZ of overall bandwidth.
The proliferation of broadband applications has created a need for more bandwidth.For example, a typical CAT7 channel can provide a bandwidth of 862MHZ for the transmission of video signals, analog audio signals on another pair, and high-speed LAN information on a third or fourth pair.
Another difference between the CAT6 patch cable and cat7 patch cable systems is their structure.The six types of wiring systems can use either UTP or STP.The seven types of systems are based only on shielded cables.In the cat7 network cables, each pair has a shield layer, and four pairs of wires together have a common shield layer.In terms of physical structure, the additional shielding layer makes the CAT7 Ethernet Cable have a larger diameter.
Another important difference is its ability to connect hardware. The parameters of the cat7 patch cable of systems require that all pairs of wires provide at least 60DB of integrated proximal winding at 600MHZ.The cat6 systems only require 43dB at 100MHZ and 46dB at 250MHZ for the cat6 patch cable.
