Problems solved by technology

[0014] It can be seen that in the prior art, the ranging operation will not start until the tag receives the base station ID. If the tag receives the timeout, the positioning will fail this time, and all previous operations will be wasted.
Therefore, whether the base station identification can be s

Abstract

The embodiment of the invention provides a method for positioning labels in a wireless network. The method comprises the following steps that the master base station obtains identifiers of slave base stations, wherein the slave base stations and the master base station are located in the same target area, and the number of the slave base stations is greater than or equal to 2; the master base station receives broadcasting messages sent by the labels and sends the identifier of the master base station and the identifiers of the slave base stations to the labels when the labels are in the target area; and the master base station obtains a second distance measurement result and sends a first distance measurement result and the first distance measurement result to a server. The embodiment of the invention also provides the master base station for positioning the labels in the wireless network. Compared with an existing UWB (Ultra Wideband) positioning scheme, the labels are allocated and managed at base station ends, so paths as short as possible are employed, the instable delay and factors are reduced to the lowest, and the positioning system is relatively reliable.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method for locating labels in a wireless network and a main base station. Background technique [0002] Ultra Wideband (UWB for short) is a carrier-free communication technology that uses nanosecond to microsecond non-sine wave narrow pulses to transmit data. Due to the ultra-wideband signal itself has low power consumption, high security, and multipath resolution. With the characteristics of strong ability, UWB has been used for high-precision positioning at home and abroad in recent years. [0003] TOA (Time of Arrival) positioning algorithm is an algorithm that utilizes signal arrival time for positioning. It is one of the basic positioning algorithms for mobile communication systems. It has the characteristics of easy access to positioning parameters and high positioning accuracy. The system architecture of the TOA algorithm is as follows: figure 1 As shown, the framewor...
