Cooperative positioning method and system based on wireless internet of things

Abstract

The invention discloses a cooperative positioning method and system based on the wireless Internet of Things, and the method comprises the steps: enabling a cooperative service node to serve as a positioning base station to analyze the object access information of service object equipment, extracting a beacon modulation state identification and a positioning signal receiving variable value, performing positioning signal receiving correction and positioning feature calculation on the positioning signal receiving variable according to the beacon modulation state identifier to obtain a calculatedvalue of a positioning feature variable of the service object device, judging based on the beacon modulation state identifier and/or the positioning characteristic variable of the service object device, and enabling the service object device to perform positioning beacon resetting and positioning state updating according to the corresponding object beacon modulation parameter when necessary. Theservice object equipment dynamically modulates and sends the object state beacons of different beacon transmitting power levels and time sequence combinations thereof based on the positioning requirements, so that unnecessary power consumption is saved, cross interference is avoided, and the positioning calculation precision, continuity and real-time credibility are improved.

AI Technical Summary

Problems solved by technology

[0007] 1) When the monitoring information of the service object equipment in the wireless edge domain network is uploaded, the selection of the upper collection service equipment and its network communication mode is usually a single wireless connection mode, and the service object equipment seldom uses the collaborative services provided by the surrounding Internet of Things. And there is a lack of corresponding wireless mode management mechanism and service specifications; although some IoTs have intelligent perception and data communication service capabilities, they are only used as collection and upload channels, and do not have collaborative perception service capabilities

[0008] 2) The service node device in the wireless edge domain network has a relatively strong ability to sense, monitor and provide data communication services to the fixed (static) service object devices that are connected wirelessly around them, but for mobile access service object devices (especially the number of large) lack of dynamic perception service capability; due to the lack of flexible wireless perception mode management and weak wireless collaborative service capability, the edge domain network lacks efficient services with compatibility and continuity for the service object equipment, and makes the service object Devices often need to pay a higher power consumption price

[0009] 3) The service node device in the wireless edge domain network has a relatively strong ability to provide data communication services (including data collection and upload) to surrounding service object devices, but lacks the ability to deal with on-si
