Method for achieving classification positioning by mobile monitoring terminal

Abstract

The invention discloses a method for achieving classification positioning by a mobile monitoring terminal. The mobile monitoring terminal comprises a detection module, a communication module, a positioning module and a height sensor, the positioning module conducts classification positioning, dynamic positioning configuration is adopted in the monitoring terminal, the positioning module comprises a wide area positioning module and an RF local area positioning module, the wide area positioning module is based on satellite GPS tracking positioning or a mobile cellular base station or an LBS tracking positioning system or a GPSONE tracking positioning mode, the RF local area positioning module is based on a WiFi or a Zigbee or a Bluetooth or a UWB, the wide area positioning module is in the continuous working state all the time, when the monitoring terminal enters the local area positioning network range, the local area positioning module is started so as to timely send RF beacons at intervals with the set RF signals, and when the monitoring target is away from the local area positioning network range, a monitoring center turns off the local area positioning module of the terminal. The method has the advantages of being accurate in positioning, wide in coverage, high in intellectualization and cruising ability and the like.

Description

technical field [0001] The invention relates to a method for realizing hierarchical positioning of a mobile monitoring terminal in the field of mobile monitoring terminals. Background technique [0002] Mobile monitoring terminals are usually used in the mobile monitoring, monitoring and security tracking of important items or personnel, such as in the logistics industry to implement security monitoring of important items. Under normal circumstances, GPS / A-GPS or GPS ONE based on satellites and mobile cellular base stations can provide more accurate positioning and tracking in outdoor environments, and can meet the requirements of object movement track tracking under normal circumstances. However, when there is space coverage or inside a building, the positioning accuracy becomes poor due to the blocking of satellite / cellular base station signals or multipath scattering, which cannot meet the requirements of finding and locating the monitored target accurately: on the other ...
