Problems solved by technology

[0006] In the prior art, using 4G or WIFI communication module to communicate with the remote host computer is not conducive to ad hoc networking and remote control, and the anti-interference performance is poor
In addition, because the UWB positioning module is always in the working state, it consumes a lot of power and has a short standby time

Abstract

The invention discloses a UWB and ZigBee-based low-power-consumption positioning label and positioning system, the low-power-consumption positioning label comprises a power supply module, a UWB positioning module and a microcontroller, the power supply ends of the UWB positioning module and the microcontroller are electrically connected with the output end of the power supply module, and the microcontroller is connected with the UWB positioning module. The UWB positioning module is used for sending the UWB ranging information to the microcontroller, and the microcontroller is used for calculating positioning information according to the ranging information; and the low-power-consumption positioning label further comprises a ZigBee wireless communication module, the power supply end of the ZigBee wireless communication module is electrically connected with the output end of the power supply module, and the microcontroller is connected with the ZigBee wireless communication module. According to the invention, the ZigBee wireless communication module is integrated in the positioning tag, so that ad-hoc network and multifunctional application of a large number of positioning tags can be realized, and remote control can be realized; the positioning label has the characteristics of low power consumption and long standby time through periodic dormancy and awakening operation, and long-term use can be ensured; and the anti-interference effect is good, the system complexity is low, and the positioning precision is high.

Description

technical field [0001] The invention belongs to the technical field of positioning, and in particular relates to a low-power positioning label and a positioning system based on UWB and ZigBee. Background technique [0002] Indoor positioning has become more and more important in the pace of urbanization. This is because in the process of urbanization, people's daily communication, shopping, office and various social activities mostly take place in indoor scenes. The positioning service of the mobile phone has also been extended from outdoors to indoors. [0003] Because the traditional satellite navigation positioning method will be blocked by buildings, complex urban environments and obstacles, it cannot achieve effective positioning in the indoor environment, and thus cannot meet people's needs for indoor positioning services. Therefore, indoor positioning technology has become a hot research field nowadays, and has become the research and development focus of academia an...
