Description
Technical field
The utility model relates to field of agricultural irrigation, particularly a kind of water saving irrigation intelligent system based on ARM.
Background technology
Agricultural is the trade that our human society is the most ancient, is the basic of each industry of each door, is also the condition that we mankind are lived simultaneously. The development of agricultural is depended on, two conditions, one is the condition of technology, and two is water condition.
The agrotechnique of innovation affects the development future of agricultural. Wanting to allow ancient artificial growth pattern automatically plant conversion towards high-tech, extensive operation transforms to intensive farming, just requires the jump that agrotechnique will be once big, starts once huge agrotechnique innovation. But agricultural or having fallen behind other industries one cuts greatly, it is particularly backward that agricultural waters the technology of irrigating. The low development seriously having tied down China's agricultural of irrigation technique. Irrigation system level of automation in the past is too low, and major part also to be depended on manual operation, though a fixed value given in advance, but well it is not effectively manipulated again, so in order to effectively improve irrigation efficiency, simplifying working time and save water resources, the research and development of water-saving irrigation technique are imperative.
A kind of technology efficiently for modern intelligent irrigation control system field irrigation management, it can effectively raising operation accuracy, facilitate the scientific management in irrigation process, and the quality for operator requires low. Precisely effective at regular time and quantity farm crop automatic watering function be can also give while significantly reducing labor capacity, quality, the output of farm crop improved, and can also saving water resource and electric power energy.
Modern irrigation controller does not also obtain a large amount of research and development in China and tries out, compare with foreign country, we are mostly is in manual plantation, even if some local system that oneself have studied some similar automatic irrigations, but that is all rely on the setting of conventional experience, can not flexible Application, if the in fact required water yield of the water yield and the farm crop irrigated is compared very little, just can not make farm crop healthy growth;And the water yield irrigated is too many, fertility runs off, and can make again the wasting of resources, and traditional irrigation method also to be controlled could use by people, such productivity too lowly, this do not meet modern agricultural development required for high-level efficiency, low labour requirement
China has bought foreign many senior irrigation systems this year, but fund consumption is too much relatively, repairs maintenance comparatively difficult, and major part can only be applied to agricultural trial plot, research unit and agricultural university, and is not suitable for the feature of China's soil property. Still it is in the starting stage in the independent studies of China and the modern irrigation controller of development. So, China is as a large agricultural country, it is necessary to develop one be attributed to from leading low cost, convenient protection, system function by force and expand simple digital Water-Saving Irrigation System. My graduation project is exactly an intelligent water-saving irrigation system designed for this present situation.
