Automatically controlled greenhouse farming system

The invention relates to an automatically controllable greenhouse cultivation system, in particular to a closed or semi-closed greenhouse, and a control and cultivation system for various growth environments and conditions required for the production of greenhouse plants by the fuel cell module green energy.

According to the traditional agricultural plant exposure to the natural environment, resulting in a large number of pests or external environmental pollution, the growing environment of planting can not be effectively controlled, can only rely on the natural climate, is a test for farmers, plus Traditional agriculture has been difficult to be controlled due to planting and production environment. It has been reported when planting cold or fever, and it is necessary to use a large amount of chemical fertilizers and highly toxic pesticides to increase the growth rate of plants and inhibit diseases and insect pests. After the human body is planted with planting products, it will have a greater health threat. Therefore, a new generation of greenhouses with fine cultivation and planting agriculture is the current trend of green agricultural technology, which can solve the problem of chemical fertilizer and pesticide pollution in the above-mentioned traditional agricultural cultivation. .

However, the conventional greenhouse planting needs to take into account the fact that the plants must perform photosynthesis in a clean greenhouse, and it is necessary to simulate the environmental factors such as the illumination, temperature, humidity, water supply irrigation and natural climate change of the plants outdoors. The plant can grow normally in the greenhouse like an outdoor environment. For example, the photosynthesis formula of plants is 12H ₂ O+6CO ₂ →C ₆ H ₁₂ O ₆ +6O ₂ +6H ₂ O. In other words, plants must borrow From the right amount of water and carbon dioxide, it can be converted into organic sugars (C ₆ H ₁₂ O ₆ ), oxygen and water through photosynthesis of the plant's own chlorophyll, that is, even if it is in the greenhouse, it must be Appropriate amount of water and moderate concentration of carbon dioxide can make the plant grow like photosynthesis in the natural environment to facilitate the normal growth of the plant.

Therefore, the conventional greenhouse planting needs to use the conventional utility power or the solar battery flaunting green energy as a power source to generate a light environment in nature, and consume a large amount of electricity by using the power source. The power conversion generates heat or water, water, spray, and other environmental conditions such as temperature, humidity, and water supply irrigation, and consumes a lot of power and power. For greenhouse plants that focus on green energy, power consumption is nothing more than The huge cost burden, and the conventional greenhouse must be organic fertilizer applied by planting, and then the natural decomposition of organic matter in the natural environment to produce carbon dioxide, or directly from the outside to supply carbon dioxide in the cylinder, in order to enable greenhouse planting Planting growth hormone with sufficient concentration of carbon dioxide for photosynthesis, so that in addition to electricity supply and illumination, it is necessary to separately plant the above-mentioned temperature, humidity, water supply irrigation and carbon dioxide plant growth and photosynthesis. The environmental resources needed for additional preparation and supply, and it is not easy to integrate the lighting, temperature, humidity, water supply irrigation and carbon dioxide and other environmental resources, and separately invest in equipment costs and consume a lot of unnecessary power, resulting in a well-known greenhouse. Planting environment equipment is complex, and equipment and planting costs are both High, resulting in the high price and high price of traditional greenhouse planting agricultural products, can only be limited to a small number of high-priced consumer groups to buy, but can not be popularized to the general civilian consumption of the mass population, which is currently the green greenhouse planting technology needs to be resolved The subject.

In the related prior patent documents, such as the Republic of China Patent Gazette No. M442023 "a plant cultivation system" new patent case, the No. I365711 "solar greenhouse" invention patent case, the M423999 "flower automatic care device" new patent case The invention patent publication No. 201309190 "Green Energy Water-saving Stem Greenhouse System" and the invention patent publication No. 201038190 "Greenhouse or Agricultural Greenhouse with Thin Film Solar Cells" respectively disclose the use of solar cells and batteries as the main power supply equipment, Providing the power required for lighting in the greenhouse, and providing the power required for the operation of equipment such as temperature, humidity, and water supply irrigation through power conversion, and still need to consume a large amount of unnecessary power during the conversion process to make the solar cell operate efficiently. If the power supply is insufficient, it is still necessary to input the auxiliary power supply of the mains power supply, and it is impossible to achieve the economic benefits of making the greenhouse planting truly enjoy the green energy and exquisite agricultural cultivation.

Similarly, the prior patents of the prior art still exist in the above-mentioned conventional greenhouse planting system, except that the illumination device can be directly input from the commercial power source or the solar power, and there is no way to directly solve the problem such as temperature, humidity, water supply irrigation and the like. The supply of environmental resources such as carbon dioxide still requires the provision and supply of equipment and resources for temperature, humidity, water supply irrigation and carbon dioxide supply. There are still complex equipment and expensive planting costs arising from the above-mentioned greenhouse planting systems. It is necessary to consume a lot of problems and shortcomings of converting power.

The main object of the present invention is to provide an automatically controllable greenhouse farming system for eliminating the conventional greenhouse planting system, which can only supply light power resources, and the equipment and resource supply such as temperature, humidity, water supply irrigation and carbon dioxide. Additional investment and supply are required, which leads to the problems and disadvantages of expensive planting and planting of greenhouse planting systems.
