Problems solved by technology

Traditional ultra-broadband positioning node deployment generally requires the use of total stations or laser range finders, and multiple measurements are required. Coordinate conversion and map stitching are also required for large areas to achieve the overall positioning node layout. Generally thousands of The workload per square meter takes 1-2 days, the larger the layout area, the more manpower and time it takes

Embodiment Construction

[0036] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0037] Such as figure 1 As shown, an autonomous position measurement method of an ultra-wideband positioning node, comprising the following steps:

[0038] Step 1, according to the degree of occlusion, partition the area to be arranged for positioning nodes, and arrange positioning nodes in each partition; specifically, the layout method and position of positioning nodes are as follows figure 2 As shown in , the positioning nodes are installed at the same height distance from the roof, so that all the positioning nodes are located in the same plane, and they are arranged in a rhombus or rectangular shape as much as possible;

[0039] Step 2, such as image 3 As shown in , among the arranged positioning nodes, select three adjacent positioning nodes that are relatively central and have a visual distance as reference positioning nodes, a...

Abstract

The invention provides an ultra wideband positioning node's own position measurement method, comprising the following steps: dividing a region to be provided with positioning nodes; arranging positioning nodes in each divided region; selecting three adjacent positioning nodes as reference positioning nodes which are almost at the heart of the region and whose ranges are visible; using the three reference positioning nodes as a center to scatter serial numbers around; obtaining the position coordinates of the three reference positioning nodes; selecting the position node with the shortest distance to the three reference positioning nodes and the smallest serial number as a to-be-tested positioning node; performing bidirectional range finding in a flying manner between the to-be-tested positioning node and the three reference positioning nodes; obtaining three time-stamp messages and transmitting the messages to a central server for the updating of the coordinate of the to-be-tested positioning node and at the same time, determining whether the coordinates of all the other positioning nodes in the region except the three reference positioning nodes are updated or not; if the updating has yet to be completed, then, using the to-be-tested positioning node as a new reference positioning node and selecting a next to-be-tested positioning node for another measurement.

Description

technical field [0001] The invention relates to the field of ultra-wideband positioning, in particular to an autonomous position measurement method of an ultra-wideband positioning node. Background technique [0002] With the rapid development of my country's Internet of Things construction, the collection of precise location information is increasingly showing its important role. Most of the location information collection of the Internet of Things is carried out when the satellite signal is poor or there is no satellite signal. In order to obtain more accurate location information, it is necessary to deploy high-precision wireless positioning nodes to achieve precise positioning. [0003] In recent years, a positioning method based on pulse ultra-wideband has emerged. Compared with other positioning systems such as Wifi, Bluetooth, and zigbee, it has the advantages of high positioning accuracy, good real-time performance, and strong anti-interference ability. However, the ...
