Layered data acquisition system applied to marine information network and method thereof

Abstract

The invention discloses a layered data acquisition system applied to a marine information network and a method thereof. A plurality of sensor nodes are arranged in a clustering manner; wherein each cluster comprises a cluster head node and a plurality of common nodes; seabed data information is collected through a plurality of common sensor nodes and then transmitted to the cluster head node in aunified mode, and the cluster head node is responsible for data summarization and transmits the data to the underwater robot, so that the use energy consumption of each sensor node is reduced, the service life of a sensor of the data collection layer is prolonged, and the data collection efficiency of the data collection layer is improved. Moreover, after each data acquisition period is completed,the data is acquired; a new sensor node is reselected from each cluster to serve as a cluster head node of the next data acquisition period; the energy loss of all the sensor nodes in the same cluster is well balanced, the data acquisition efficiency of the whole cluster is improved by continuously replacing the cluster head node in turn, the energy utilization maximization of all the sensor nodes in the cluster is realized, and the method is more energy-saving and efficient.

Description

technical field [0001] The present invention relates to the technical field of marine data information collection, in particular to a layered data collection system applied to a marine information network, and also to a layered data collection method applied to a marine information network. Background technique [0002] In recent years, the marine communication network has received extensive attention. Understanding the ocean, developing the ocean, managing the ocean, and comprehensively building a maritime power have been raised to a new strategic height. To support the construction of a marine power, marine information networks are essential. How to design a oriented A stable, efficient, and low-energy data acquisition system for marine information networks has become a core task. [0003] The current conventional data acquisition system is to arrange multiple sensor nodes at different depths in the ocean to collect and transmit underwater information. Through the multi-ho...
