A sensor node positioning system supporting wlan fingerprint positioning

Abstract

The invention belongs to the technical field of positioning systems, specifically a sensor node positioning system supporting WLAN fingerprint positioning, including a monitoring module, an environment analysis module, an auxiliary positioning module, a search module and a sharing module; the monitoring module is used for real-time monitoring of transmission The monitoring module includes an image input unit, an image analysis unit, an image database, and an image screening unit; the image input unit is used to input the surrounding scenery into the mobile terminal; the image analysis unit is used to analyze the input scenery; The environment analysis module is used to analyze the environment-assisted positioning of the position; the present invention records the scenery around the position of the sensor node into the mobile terminal through the image input unit of the monitoring module, such as shops and streets; Stores and streets are compared and searched in the image database, and finally the most suitable image is determined by the image screening unit, so as to determine the position of the sensor node at this time.

Description

technical field [0001] The invention belongs to the technical field of positioning systems, in particular to a sensor node positioning system supporting WLAN fingerprint positioning. Background technique [0002] In the existing technology, with the development of the tourism industry, more and more people choose to travel in groups during holidays. During group travel, the travel agency must keep abreast of the location of the tour group or tourists, so as to understand and respond to some temporary emergencies situation, this requires the mobile terminal equipment of tourists to obtain their location and report it to the server, and the GPS module or Beidou navigation module that can accurately locate will consume a large amount of power of the mobile terminal when called, which results in no need to obtain The GPS module or the Beidou navigation module is still used to obtain the precise location of the tourists, which causes a large amount of power consumption of the mob...

[0002] In the existing technology, with the development of the tourism industry, more and more people choose to travel in groups during holidays. During group travel, the travel agency must keep abreast of the location of the tour group or tourists, so as to understand and respond to some temporary emergencies situation, this requires the mobile terminal equipment of tourists to obtain their location and report it to the server, and the GPS module or Beidou navigation module that can accurately locate will consume a large amount of power of the mobile terminal when called, which results in no need to obtain The GPS module or Beidou navigation module is still used to obtain the precise location of tourists, resulting in a large amount of power consumption of the mobile terminal and shortening the standby time of the mobile terminal

On the other hand, in some stores, it is difficult for GPS modules or Beidou positioning modules to receive signals. If these positioning modules are still turned on at this time, it will cause a waste of power, and it is impossible to perform positioning. It is difficult to judge whether tourists have arrived at these stores. At this time, it is also necessary to use a device that can replace the GPS or Beidou positioning module that cannot receive signals for positioning
