Positioning base station applied to ultra wideband positioning system, system and positioning method

Abstract

The invention provides a positioning base station applied to an ultra wideband positioning system, a system and a positioning method. According to the embodiment of the invention, the positioning base station in the ultra wideband positioning system is configured as follows: the plurality of positioning base stations share one positioning processor, and the positioning base stations do not have functions of the positioning processor. Compared with the prior art, the positioning base station provided by the embodiment of the invention is adopted under a positioning scene where the same quantity of positioning base stations need to be configured, so that a lot of positioning processing devices can be saved, and thus the arrangement cost of the whole positioning system is reduced; on the other hand, the plurality of positioning base stations share the one positioning processor, and pulse signals of the plurality of positioning base stations can be processed by the one positioning processor, so that the plurality of positioning base stations can work under the same time standard. The defect that time standards of a plurality of positioning processing devices in an existing system are unified is avoided, so that the configuration working amount is reduced, and the problem that the positioning precision is reduced, caused by the fact that the configuration of the time standards is not uniform, is solved.

Description

technical field [0001] The invention relates to the technical field of ultra-wideband positioning, in particular to a positioning base station, a system and a positioning method applied to an ultra-wideband positioning system. Background technique [0002] The frequency band used by the UWB (Ultra Wideband, ultra-wideband) technology is specified to be between 3.1 and 10.6 GHz. Due to the high operating frequency, the signal diffraction capability and penetration capability are limited. In the existing positioning technology using UWB, each reference node has an independent antenna, transmission line and positioning processing device. The positioning processing device is used to solve the signal to realize the positioning of the signal source. When positioning the same area, usually 3 to 4 reference nodes are required to work at the same time. In the application of multiple small rooms indoors, each room must be equipped with 3 or more reference nodes to achieve plane posit...

Problems solved by technology

When positioning the same area, usually 3 to 4 reference nodes are required to work at the same time. In the application of multiple small rooms indoors, each room must be equipped with 3 or more reference nodes to achieve plane positioning. Because each All reference nodes need to be equipped with a positioning processing device, and the stand-alone cost of the positioning processing device is high, so that the overall cost of the system remains high

Moreover, since multiple positioning base stations are equipped with independent positioning processing devices, it is necessary to configure the same time reference for a large number of positioning processing devices, the configuration workload is heavy, and the accuracy is difficult to guarantee
