[0034] In indoor positioning technology, if there are multiple tags working in the same area, the time when the positioning request signals sent by multiple tags arrive at the base station will inevitably overlap, that is, data collision will occur. This embodiment uses ultra-wideband (UWB) indoor Taking positioning as an example, a label positioning system is provided to solve the collision problem of multiple labels. figure 1 A schematic diagram of a tag positioning system provided by an embodiment of the present application is shown, the system includes: a master base station 101, a plurality of slave base stations 102, a plurality of tags 103 and a server 104, and the tag 103 may be a UWB tag, which may be applied For stationary or moving objects, or for personnel positioning tracking and navigation, the master base station 101, the slave base station 102, and the tag 103 are all in the same target area.

[0065] This embodiment provides a label positioning device, which is configured on any one of multiple labels in the target area, and a master base station and a plurality of slave base stations are also arranged in the target area, and the master base station and the slave base stations are connected to the server by communication , see Figure 4 , the device consists of:

[0066] A broadcast module 301, configured to broadcast a request frame in the target area;

[0067] The response module 302 is configured to receive a first beacon frame from the master base station, and send a first data frame to the master base station and multiple slave base stations in response to the received first beacon frame, where the first beacon frame is the master base station After receiving at least one request frame broadcast by multiple tags, it is generated for a selected request frame, the first data frame carries the time point when the first data frame is sent from the tag, and the fir...

[0080] This embodiment provides a label, including a processor and a signal transceiver, the processor is connected to the signal transceiver, and the signal transceiver can transmit signals to the main base station and the secondary base station in the target area through the antenna to realize communication. The label can be The tag provided on the target object provided in the first embodiment, the processor in the tag is used to execute the tag positioning method performed by any tag in the target area in the first embodiment, the tag can be a UWB tag, and can be set on Objects, vehicles, helmets, and personnel are positioned. When there are multiple tags working in an area, after the main base station selects a tag for processing, the tag enters a silent state and rebroadcasts the request frame after the silent end. The time point of a tag broadcast request frame is staggered according to the order in which the main base station selects and responds. Therefore, the target ...

Abstract

The embodiment of the invention provides a label positioning method, system and device. The method applied to any label in a target area comprises the following steps: broadcasting a request frame inthe target area; receiving a first beacon frame from the master base station, and generating the first beacon frame for the selected request frame after the master base station receives at least one request frame broadcasted by a plurality of tags; in response to the received first beacon frame, sending a first data frame to the master base station and the plurality of slave base stations, the first data frame carrying a time point at which the first data frame is sent from the tag; and keeping the silent state of not broadcasting the request frame within the preset time length, and finally, after receiving the data frame sent by the base station, enabling the server to position the label according to the time point in the data frame. Because the tag does not broadcast the request frame after entering the silent state, the main base station selects one request frame again to respond, and the processing time of the request frame is inevitably later than that of the last selected tag, sothat the collision problem is solved.

Description

technical field [0001] The present application relates to the technical field of positioning, and in particular, to a tag positioning method, system and device. Background technique [0002] With the emergence of emerging industries such as artificial intelligence and unmanned industry, indoor positioning technology is also gradually developing. Using base stations and tags set on target objects can complete the positioning of the target object and the moving path of the target object in the indoor environment. to track. In scenarios where there are many individuals that need to be located, such as exhibition halls, firefighting, and large playgrounds, multiple tags work in the same area. Since multiple tags will send positioning requests to the base station, there will be positioning sent by different tags. The request signals arrive at the base station at the same time. If this happens, the base station can only process one signal, and the other positioning request signal...
