Abstract

The invention discloses a wireless sensor network locating system. The system comprises one or more located targets, recognition nodes, a relative distance calculation module, a recognition node angleacquisition module and a server. The recognition nodes are internally provided with Zigebee modules and Beidou modules, and are used for information interaction with one or more task management nodein a wireless card reading station. The relative distance calculation module is used for calculating relative distances between the recognition nodes and wireless card readers. The recognition node angle acquisition module is used for acquiring angles formed by an unknown node and three adjacent known recognition nodes according to coordinate data of the Beidou modules. The server is used for acquiring coordinate data of the unknown node according to the relative distances and the angles. The wireless sensor network locating system has the advantages that working quantity and complexity duringlocating can be reduced, and locating accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a wireless sensor network positioning system. Background technique [0002] With the development of microelectromechanical system, system on chip, wireless communication and digital electronic technology, wireless sensor network, as a new information acquisition and processing mode, has the characteristics of low power consumption, low cost, distribution and self-organization, and has huge application prospects. A wireless sensor network is a wireless network composed of a large number of stationary or moving sensors in a self-organizing and multi-hop manner to cooperatively perceive, collect, process, and transmit information about perceived objects in the geographical area covered by the network, and finally transfer these Information is sent to the owner of the network. [0003] For wireless sensor networks, positioning technology is a key part of its functional applic...
