Embodiment 1

[0035] see figure 1 , a positioning method in a complex environment provided by an embodiment of the present application, including:

[0036] Step S101, receiving a positioning signal sent by the target to be positioned, and determining the relative distance between the target to be positioned and the positioning device according to the positioning signal;

[0037] In the application, when the positioning signal sent by the target to be positioned can be searched or received, the relative distance between the target to be positioned and the positioning device can be determined through wireless communication technology according to the positioning signal. The wireless communication technology may be a wireless communication technology such as Ultra WideBand (UWB), Wireless-Fidelity (Wi-Fi) or Radio Frequency Identification (RFID).

[0038] In a specific application, it is assumed that the target to be located is a firefighter who needs to be located. The firefighter carries eq...

Abstract

This application is applicable to the field of positioning technology, and provides a positioning method, device and positioning equipment in a complex environment, wherein the method includes: receiving a positioning signal sent by the target to be positioned, and determining the target to be positioned and the positioning device according to the positioning signal the relative distance; obtain the historical motion data of the target to be positioned; determine the relative height value and relative angle value between the target to be positioned and the positioning device according to the historical motion data; according to the relative distance, the relative height value and the relative angle value to obtain relative position information between the target to be positioned and the positioning target. Accurate positioning can be performed in a complex environment without communication with satellites, or without pre-arranging reference nodes around the environment, thereby improving positioning efficiency in complex environments.

Description

technical field [0001] The present application belongs to the technical field of positioning, and in particular relates to a positioning method, device and positioning equipment in complex environments. Background technique [0002] The large amount of economic losses and casualties caused by large and medium-sized building fire accidents every year have aroused widespread concern from people from all walks of life in China. In the face of complex and dangerous fire rescue scenes, firefighters need to locate the firefighters in time when performing tasks in the fire scene, so that rescue and other operations can be carried out quickly and efficiently. [0003] Existing positioning technology generally uses positioning targets to communicate with satellites to achieve positioning, or arranges reference nodes around the environment in advance, and combines the position information of reference nodes for wireless positioning. When in buildings, underground, tunnels and other pl...
