Multi-mode wireless position tracking method and system

Abstract

The invention discloses a multi-mode wireless position tracking method, according to current mode, state and / or availability of surrounding position tracking service wireless network resource, a tracked position triggering device performs automatic selecting and switching according to a preset priority mechanism and switching conditions on a position acquiring mode and / or a transmission communication mode of the position triggering device position information, and the position information of the position triggering device is transmitted to one or more associated tracking monitoring equipment; the surrounding position tracking service wireless network resource comprises wireless positioning associated nodes and wireless communication networks; when the position triggering device detects that there are / is wireless Bluetooth positioning associated nodes and / or bluetooth associated node network which can acquire position tracking service nearby, the non-bluetooth position mode and / or non-bluetooth communication mode can be automatically closed or applied restrictively, so that the position precision is improved, and power consumption is saved. The invention also discloses a multi-mode wireless position tracking system.

Problems solved by technology

However, for small tracked wearable positioning devices, the main problem is that the battery capacity is insufficient, and the continuous positioning of the battery does not last long enough (usually only a few hours).

On the one hand, the power consumption current of the above positioning methods is relatively large, on the order of tens of mA; on the other hand, many wearable products do not have WiFi functions due to cost and power consumption constraints. When there is no GPS signal indoors, it needs to switch To the base station positioning method, its positioning accuracy depends on the distance between nearby base stations, which often leads to large positioning errors
