UWB positioning system for robot

Abstract

The invention, which belongs to the field of indoor autonomous navigation technology, provides a UWB positioning system for a robot. The UWB positioning system is composed of a positioning module, a survey module, a data processing module, a control module. The GPS technology is combined with the UWB technology by the positioning module; the GPS technology is used for locating the outdoor positionof the robot; and the UWB technology is used for positioning of the indoor position. The survey module provided with several kinds of detecting units is used for detecting different environmental data and exchanging data with a graphic drawing unit in the control module for research and rescue work. The control modes have an active control mode and a passive control mode. A CPU data analysis unitof the system carries out data analysis and makes a route by itself; and a moving route can be fixed by means of manually and remotely controlled instruction issuing or program. With the UWB technology, a problem of unstable indoor signal transmission is solved; and the transmission rate and the space capacity are high; the cost is low; and the power consumption is low.

Description

technical field [0001] The invention relates to the technical field of indoor autonomous navigation, in particular to a UWB positioning system for robots. Background technique [0002] At present, due to the wide application of GPS and Beidou navigation satellites, the development of outdoor navigation and positioning technology is becoming more and more mature. However, because satellite signals are difficult to penetrate indoor buildings, and the indoor environment is very complex, the existence of multipath and non-line-of-sight interference makes it difficult to realize indoor navigation and positioning or to truly meet application requirements. [0003] However, indoors is the place most closely related to human life and work, and there are a large number of application requirements for indoor navigation and positioning services. For example, in firefighting operations, the nature of firefighters' work is highly dangerous. They may enter some complex high-rise building...

AI Technical Summary

Problems solved by technology

For example, in firefighting operations, the nature of firefighters' work is highly dangerous. They may enter some complex high-rise buildings, and their own safety becomes a problem. The path effect is serious and positioning is difficult. At this time, a robot is needed as a pathfinder to detect the fire situation and confirm the position of the trapped people through identification. Another example is today's logistics, most of which are still moved by humans and record logistics information, but Traditional logistics consumes manpower and is prone to errors in storing data records. For example, when working in a nuclear radiation area, personnel entering the radiation environment may easily cause physical lesions of the staff. At this time, robots are required to operate simple tasks and can act as The role of the guide, choose a path with a small amount of radiation, and guide the staff through the radiation area
