Embodiment

[0027] see figure 1 The present invention provides a technical solution: a method for detecting a water environment pollution source based on a wireless sensor network. The method for detecting a water environment pollution source based on a wireless sensor network is as follows:

[0028] S1: Divide the water environment area to be measured into i groups of areas to be measured, and label them with P i (i=1, 2, 3...), each group of areas to be tested is provided with a sink node and n sensor nodes, and the label of the sink node is X i (i=1, 2, 3...), the sensor node label is Y n (n=1, 2, 3...), each sensor node has a water environment pollution source probe, and each group of sensor nodes in the area to be measured is converged with the group of sensors in the area to be measured by multi-hop communication The nodes are connected, and multiple aggregation nodes are respectively connected with the protocol converter through the wireless network. The protocol converter is con...

Abstract

The invention belongs to the technical field of wireless sensor network technology, and particularly relates to a water environment pollution source detection method based on a wireless sensor network, which comprises the following steps: grouping water environment areas to be detected, distributing aggregation nodes, positioning sensor node distribution by using water environment pollution sources, and detecting the pollution source of the water environment based on the wireless sensor network. According to the method, the to-be-detected water environment areas are grouped, grouping positioning can be facilitated, multiple point pollution sources can be conveniently positioned at the same time through multi-group positioning, and therefore it is avoided that positioning of the point pollution sources is affected by the point pollution sources existing at the same time; according to the invention, the sink node and the sensor node are used for tracking the water environment pollution source, and then the data management software and the water environment pollution source detection software are used for pre-judging the moving trajectory of the line pollution source, so that search personnel can find the line pollution source in time.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a method for detecting a water environment pollution source based on a wireless sensor network. Background technique [0002] Water environment pollution sources are the sources of pollutants that cause water pollution. Usually refers to places, equipment and settings that discharge pollutants into waters or have harmful effects on the water environment. According to the source of pollutants, it can be divided into two categories: natural pollution sources and man-made pollution sources. Man-made pollution sources can be divided into industrial, agricultural, living, transportation and other pollution sources according to the way of human activities; according to different types of pollutants, they can be divided into organic, inorganic, thermal, radioactive, heavy metals, pathogens, etc. The mixed pollution source of pollutants; according to the different spat...
