Irrigation equipment network regulation and control method, equipment and system based on SDN

Abstract

The invention relates to an irrigation equipment network regulation and control method, equipment and system based on an SDN. The method comprises the following steps: obtaining a network topology structure of network equipment; adjusting the network topology structure of the network equipment according to the indication of the user and / or a preset network topology structure adjustment algorithm;and calculating the guaranteed bandwidth of the adjusted network topology structure according to a preset bandwidth algorithm, and adjusting the bandwidth of the network equipment based on the calculation result of the bandwidth so as to regulate and control the network of the irrigation service equipment. The SDN controller is added to the crop irrigation network system, centralized configurationof network topology is achieved through the SDN controller, and human input generated by network environment reconfiguration due to equipment replacement or irrigation environment change is reduced;according to the change of the definition identifiers of the crop information collection components, bandwidth regulation and control are carried out on the network where the components with differentpriorities are located through the SDN controller, so that the data forwarding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of SDN (Software Defined Network), in particular to an SDN-based irrigation equipment network regulation method, device and system. Background technique [0002] With the increasingly tense water resources, in agricultural production activities, people are gradually paying attention to ensuring the water use for agricultural irrigation and improving the water use efficiency as much as possible in agricultural irrigation. For example, the relatively mature sprinkler irrigation and micro-irrigation technologies at this stage, these agricultural irrigation technologies can send water from the water source to the farmland in a timely and appropriate amount, and allocate water resources in a timely manner according to the needs of crop growth, saving water resources and increasing water consumption. Possibility to grow crops on multiple levels. [0003] However, these agricultural irrigation technologies rely on...

Problems solved by technology

[0003] However, these agricultural irrigation technologies rely on the Internet. When the network bandwidth is limited, how to adjust the topology structure and traffic bandwidth of the network environment according to changes in the irrigation environment has become an urgent problem to be solved by those skilled in the art.
