Abstract
The invention discloses an ultra-low power consumption indoor and outdoor hybrid positioning system. The system comprises a plurality of iBeacon base stations which are arranged indoors and broadcast general unique identification codes through Bluetooth by preset signal intensities; a positioning node, wherein the positioning node is arranged on a moving object to be positioned, periodically monitors the plurality of general unique identification codes and the corresponding signal intensities around the positioning node through Bluetooth and outputs the monitored result by means of LoRa; a wireless gateway used for receiving the plurality of general unique identification codes and the signal intensity information and outputting the plurality of general unique identification codes and the signal intensity information through a mobile network; and a cloud platform used for receiving the plurality of general unique identification codes and the signal intensities and determining the latitude, longitude and indoor position of the moving object. According to the invention, by adopting the iBeacon technology based on Bluetooth indoors and adopting a GNSS positioning technology outdoors, precise positioning and seamless switching are realized, low power consumption and long distance transmission is realized by means of the LPWAN gateway, the positioning precision is high, the power consumption is low, the distance is long, and the system is suitable for large-scale popularization and application.
Description
technical field [0001] The invention relates to a positioning system. More specifically, the present invention relates to an ultra-low power consumption indoor and outdoor hybrid positioning system. Background technique [0002] Indoor and outdoor positioning technology has broad application prospects, but it faces some problems: GPS positioning is mainly for outdoor positioning, but due to building occlusion, it is difficult for GPS positioning technology to be practically applied in indoor positioning; base station positioning represented by AGPS can solve indoor positioning. Positioning needs, but the information interaction between mobile devices and telecom base stations generates a lot of traffic costs, and the power consumption of mobile devices is also very high; indoor positioning technologies such as UWB can meet indoor positioning, but cannot accurately locate outdoors. Therefore, there is an urgent need for an indoor and outdoor hybrid positioning system with hi...
