Embodiment Construction

[0027] The present invention will be further explained below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, a method for detecting mesoscale eddies with incrementally deployed sensors, which fully considers the functional parameters of the actual ocean detection sensors and the detection method of ocean mesoscale eddies, includes the following steps: First, determine the ocean eddy based on satellite altimeter data The position and spatial scale of the sensor are constructed, the velocity field of the vortex area is constructed, the sensors are deployed in the target area by uniform deployment, and the mathematical model of sensor deployment is established. Then, when the sensor coverage in the target area drops to the threshold, the number of sensors that need to be incrementally deployed is determined according to the number of effective sensors in the target area. Finally, sensors are incrementally deployed based on the location of voids...

Abstract

The invention discloses a mesoscale eddy detection method for incrementally deploying sensors. The mesoscale eddy detection method comprises the steps of: determining the position and the spatial scale of an ocean eddy according to satellite altimeter data, constructing a velocity field of an eddy region, deploying sensors in a target region in a uniform deployment mode, and establishing a mathematical model for sensor deployment; then, after the sensor coverage degree of the target region is reduced to a threshold value, determining the number of sensors needing to be incrementally deployed according to the number of effective sensors in the target region; and finally, incrementally deploying the sensors according to hole positions in the target region. According to the method, the sensorcoverage rate of the target region can be effectively enhanced by adopting a mode of deploying the sensors incrementally, and the detection of the ocean mesoscale eddy is achieved.

Description

technical field [0001] The invention discloses a mesoscale eddy detection method for incrementally deployed sensors, which belongs to the technical field of wireless sensor networks, and is particularly suitable for using sensors to detect temperature, salt density data and eddy structure characteristics of ocean mesoscale eddies. Background technique [0002] Mesoscale eddies play an important role in ocean dynamics and transport of heat, salt and other chemical substances, and are an important research content of marine science. However, the data obtained by Argo buoys can hardly meet the resolution requirements for the study of mesoscale eddies, and the inversion of satellite altimeter can only obtain sea surface anomaly data, but cannot obtain underwater data. The need for the study of scale vortex mechanism. Disposable sensors are carried by scientific research ships, and high-density detection data can be obtained by deploying sensors in the target area. At the same ...
