Water-saving irrigation internet of things integrated system for crop cultivation and operation method

Abstract

The invention discloses a water-saving irrigation internet of things integrated system for crop cultivation. The system comprises a WSN (Wireless Sensor Networks) ad-hoc network for crop greenhouse cultivation and a node deployment module; the ad-hoc network comprises an ad-hoc network formed by WSN nodes and a WSN base station; the WSN nodes include sensor nodes, control nodes, a gateway and a relay node; a virtual force algorithm based on a variable step is adopted by the node deployment module to deploy the sensor nodes in a node static sensing range; and the virtual force algorithm based on the variable step changes a movement step of each of the sensor nodes based on a sigmoid function by establishing a two-dimensional planar model of a cultivation area and a sensing model of each ofthe nodes. According to a water-saving irrigation WSN node deployment algorithm for the crop cultivation provided by the invention, while the later convergent stability is guaranteed, the purpose of optimal effect for covering an equal number of nodes in a relatively short time can also be achieved; and thus, the time for obtaining a deployment strategy is shortened, the monitoring coverage rate is improved, and the comprehensiveness and the integrity of data monitoring are guaranteed.

Description

technical field [0001] The invention relates to an integrated system and an operating method of the system, in particular to an integrated system and an operating method of the Internet of Things for crop cultivation water-saving irrigation. Background technique [0002] Wireless sensor network is a self-organizing network composed of a large number of sensors in the form of wireless multi-hop communication. Applying wireless sensor network to the field of modern agriculture can not only efficiently perceive, monitor and regulate agricultural environmental information and crop growth information, but also change the traditional The production mode of agriculture promotes the transformation of agriculture to the direction of refinement and intelligence. However, due to the limited computing power, storage capacity and transmission capacity of sensor nodes in wireless sensor networks, there are still many problems to be solved in the large-scale application of wireless sensor ...
