Embodiment Construction

[0013] The specific embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] Such as Figures 1 to 2 As shown, a specific implementation of the signal connection mode and the internal structure of each component of the mobile coordinate precise positioning system of the present invention is given.

[0015] The mobile coordinate precise positioning system is composed of a controller, a horizontal base station group, a vertical base station group and several tags to be positioned. The controller is composed of a synchronization control module and a signal processing module. The horizontal base station group includes at least two Base stations at the same level, the vertical base station group includes at least two base stations whose projections overlap in the vertical direction, the tag can transmit frequency-modulated continuous waves to the indoor space after receiving the signal transmitted by the b...

Abstract

A moving coordinate accurate locating system comprises a controller, a horizontal base station group, a vertical base station group and a plurality of labels to be located. The controller comprises a synchronous control module and a signal processing module. The horizontal base station group comprises at least two base stations placed on the same horizontal height. The vertical base station group comprises at least two base stations with coincident projection in the vertical direction. The labels can emit frequency modulation continuous waves to indoor space after receiving signals emitted by the base stations. The synchronizing signal transmission delay between the controller and various base stations in the same base station group is the same. Through a digital signal processing algorithm, the influence on locating accuracy from rough synchronous errors between the base stations and the labels can be removed, during digital signal processing, the distances between the labels and various base stations obtained by computing are subjected to subtracting in a pairing mode, real-time errors are removed, and accurate locating on the labels is achieved.

Description

technical field [0001] The invention belongs to the field of electronic communication and relates to a mobile coordinate precise positioning system. Background technique [0002] With the development and popularization of information technology and wireless communication technology, people's demand for positioning and navigation is increasing day by day. The Global Positioning System (GPS) is currently the most widely used positioning technology, which can meet people's needs for outdoor positioning. However, when the GPS receiver works indoors, the signal strength is greatly reduced by the influence of buildings, and the receiver cannot perform positioning. However, with the continuous development of modern society, the urbanization process is accelerating, and large-scale buildings are increasing day by day. People spend more than 80% of their time in indoor environments (including underground, mines, tunnels, etc.). Demand is increasing rapidly. Public safety, producti...
