Field irrigated area irrigation system based on CAN bus

Abstract

The invention discloses a field irrigated area irrigation system based on a CAN bus. The system comprises a system upper control center and lower nodes. The system upper control center and the lower nodes are in communication through a conversion card. The system upper control center and a peripheral terminal are in communication through the internet. According to the field irrigated area irrigation system based on the CAN bus, irrigation cell node configuration is flexible, increase and decrease are easy, and extension is convenient. A certain node can be automatically separated from the buswhen going wrong, normal work of other modules is not affected, and therefore the fault tolerance performance of the whole system is improved. Due to the distributed structure, each node has the autonomous capacity, functional nodes are controlled to be matched for processing mostly, the data transmission quantity of communication lines is greatly reduced, and meanwhile the work pressure of a computer center is also greatly reduced. Through internet transmission and publishing, remote monitoring can be conveniently achieved.

Description

technical field [0001] The invention relates to a field irrigation area irrigation system based on a CAN bus, which belongs to the technical field of agricultural automation. Background technique [0002] The process of irrigation water from the water source to the field, to being absorbed by crops and forming yields includes four links: water resource allocation, water distribution, field irrigation and crop absorption; the corresponding water-saving measures taken in each link constitute a A complete water-saving irrigation technology system, including water resource optimization and allocation technology, water-saving irrigation engineering technology, agronomic and biological water-saving technology and water-saving management technology; To meet the water demand of crops to the greatest extent, to achieve the best regional benefits of water regulation and management technology, which includes: automatic irrigation water management information system, automatic measureme...

[0002] The process of irrigation water from the water source to the field, to being absorbed by crops and forming yields includes four links: water resource allocation, water distribution, field irrigation and crop absorption; the corresponding water-saving measures taken in each link constitute a A complete water-saving irrigation technology system, including water resource optimization and allocation technology, water-saving irrigation engineering technology, agronomic and biological water-saving technology and water-saving management technology; To meet the water demand of crops to the greatest extent, to achieve the best regional benefits of water regulation and management technology, which includes: automatic irrigation water management information system, automatic measurement and monitoring technology of water transmission and distribution, automatic monitoring technology of soil moisture, water saving Irrigation systems, etc. Among them, the automatic measurement and monitoring technology of water transmission and distribution adopts high-standard measurement equipment to timely and accurately grasp the water conditions in irrigation areas, such as the water level and flow of reservoirs, rivers and channels, and the operation of pumps. Within the range, the average effective rate of irrigation water is only 37%, and the remaining 63% is wasted; this not only wastes water, increases costs, but also causes the loss of nutrients, and more seriously, causes soil salinization and water pollution. waterlogging, groundwater contamination, and transmission of certain diseases such as malaria and schistosomiasis
