Precision agriculture oriented WSN (wireless sensor network) network partition and terminal node deployment method

Abstract

The invention provides a precision agriculture oriented WSN (wireless sensor network) network partition and terminal node deployment method. The method includes partitioning a monitoring range into different areas, partitioning each area into different blocks, and drawing a network partition map for position labeling; initially deploying node positions of route collector terminals and non-route collector terminals and labeling the positions; initializing frequency and transmitting power of the collector terminals; adjusting the node positions of the route collector terminals and the non-route collector terminals; combining an adjusted terminal node position map with the network partition map to form a network partition and terminal node deployment map. Through reasonable terminal node deployment, data of multiple collection areas or different blocks of multiple areas are collected accurately, accurate and uniform early-warning and adjusting are performed, and a real-time accurate wireless sensor network system capable of monitoring and adjusting real-time conditions of equipment at designated locations is established, so that labor cost is reduced, and agricultural production efficiency is improved.

Description

technical field [0001] The invention relates to the field of agricultural information technology, in particular to a WSN network division and terminal node deployment method for precision agriculture. [0002] Background technique [0003] Precision agriculture is an ecological planting that uses sensors, network communications, and computer technology to collect and analyze crop growth environment parameters to save water and fertilizer, prevent pests and diseases, and reduce pesticide spraying. At present, the information collection network is divided into wired and wireless. The wired network consumes a large amount of wires, the initial investment cost is high, and the construction and maintenance workload is heavy, while the wireless sensor network is due to its low energy consumption, reliable transmission, and flexible node deployment. The market favors it, but the current deployment of wireless network nodes is based on the average distribution of information grids...

At present, the information collection network is divided into wired and wireless. The wired network consumes a large amount of wires, the initial investment cost is high, and the construction and maintenance workload is heavy, while the wireless sensor network is due to its low energy consumption, reliable transmission, and flexible node deployment. The market favors it, but at present, the deployment of wireless network nodes is based on the average distribution of information grids and information points. The data collection points in the monitored area cannot be accurately located, resulting in waste of terminal nodes, driving up costs, and bringing troubles to node maintenance and management.
