Abstract

The invention relates to a detecting method of water environment pollution source based on wireless sensor networks. The technical scheme is that, firstly, n sensor nodes are uniformly arrayed in a to-be-detected water environment area, the sensor nodes are all connected with a sink node in a wireless multi-hop method, the sink node is wirelessly connected with a gateway, and the gateway is connected with a data management center through a data wire; a management software is mounted in the data management center and includes a detecting module and a positioning module of the water environment pollution source; and finally, as long as the collected data of the sensor nodes is substituted into the detecting module and the positioning module of the water environment pollution source by the management software of the data management center, the pollution source can be detected and the position coordinates of the pollution source can be calculated. Therefore, the invention has the advantages of simplicity and convenience for carrying out, high precision, strong operability, low cost and short-time efficiency, and provides a more advanced method for the actual detecting and positioning of the water environment pollution source.
