Abstract

The invention discloses a real-time pedestrian positioning system and method based on an SoC, and the system and method can achieve the autonomous positioning through an SoC terminal without dependence on external information, solve a problem that there is no GPS signal but there is a need for positioning, and also solve a problem that there is a need to deploy a node in advance and a problem thata GPS signal is weaker. According to the invention, the FPGA is used for position calculation, the power consumption is very low and is only about 2.7 W, and the system can be used for long-time endurance; in addition, the SoC platform is small in size, and it is ensured that the whole SoC terminal is convenient to carry. According to the invention, the FPGA is used for position calculation, compared with a traditional ARM terminal, the processing speed is faster, and the position information of pedestrians can be obtained in real time.

Description

technical field [0001] The invention belongs to the technical field of pedestrian positioning and navigation, and in particular relates to the design of an SoC-based real-time pedestrian positioning system and method. Background technique [0002] Internet of Things applications such as map navigation, takeaway ordering, and Didi taxis have brought great convenience to our lives. In these applications, GPS / BD positioning technology plays a key role. Even indoors, we can achieve more accurate positioning by deploying WiFi, Bluetooth and other nodes in advance. However, in the case of forests, tunnels, underground and other external signals (GPS / BD, WiFi, etc.) are weak or even absent, we need to find other methods to achieve location tracking. [0003] GNSS (Global Navigation Satellite Systems, GNSS) has matured day by day. It is a space-based radio navigation and positioning system that can provide users with all-weather 3-dimensional coordinates, speed and time information...
