Abstract

The mobile terminal comprises a personnel positioning system based on combination of Beidou and indoor positioning. The personnel positioning system comprises a mobile terminal, a fixed terminal and a monitoring terminal, wherein the mobile terminal comprises a Bluetooth unit, an ultrasonic wave transmitting module, a Beidou positioning unit, a data processing module and a wireless communication module; the fixed terminal comprises a Bluetooth antenna, an ultrasonic wave receiving module, an infrared distance measuring module, a microprocessor and a wireless transmitting module; and the monitoring terminal comprises a wireless receiving module, a central processor and a display module. The personnel positioning system extracts coordinates of indoor staff by means of the Bluetooth antenna, the ultrasonic wave receiving module and the infrared distance measuring module, and forms final indoor positioning information by integrating positioning information of the Bluetooth antenna, the ultrasonic wave receiving module and the infrared distance measuring module, so as to combine with a Beidou positioning system to realize seamless switching of indoor and outdoor positioning, and improve indoor and outdoor positioning precision.

Description

technical field [0001] The invention belongs to the field of positioning systems, in particular to a personnel positioning system based on the combination of Beidou and indoor positioning. Background technique [0002] Satellite positioning systems mainly include the GPS system of the United States, the Beidou satellite positioning system of my country and the GLONASS system of Russia. Satellite positioning technology is mainly used in outdoor positioning. It has been developed for a long time. The deployment of satellite positioning system is large-scale and costly. It is becoming more and more mature and widely used. Its positioning accuracy and real-time performance can meet the general requirements of mobile terminal users. However, because signals are easily affected by factors such as occlusion and multipath propagation, reliable positioning accuracy and availability cannot be guaranteed in dense urban buildings and indoor confined spaces.
