Embodiment 1

[0079] see figure 1 , which is a schematic flowchart of a robot positioning method provided in the embodiment of the present application, the process may include:

[0080] S101, initialize the robot positioning central management system, import the environment map, and establish the environment coordinate system;

[0081] S102, the robot positioning central management system determines whether the operation of the communication system is normal; if normal, execute S103, and if not normal, execute S106;

[0082] It should be noted that the communication system may be WiFi6. As a preferred example, WiFi6 uses IEEE802.11axWiFi as the technical standard, and adopts OFDMA orthogonal frequency division multiple access technology to improve transmission efficiency, and adopts 1024-QAM technology and improved wireless link control (MAC). Whether there is any abnormality in the parameters such as the transmission rate and signal strength of the WiFi6 communication system in the test ...

Abstract

The application discloses a robot positioning method and system, which are used to improve the positioning accuracy and efficiency of the robot. The robot positioning method provided by this application includes: initializing the robot positioning central management system, importing an environmental map, and establishing an environmental coordinate system; the robot positioning central management system determines whether the operation of the communication system is normal; if the robot positioning central management system determines The operation of the communication system is normal, then the robot determines the WiFi fingerprint location candidate location point and the environmental image information location candidate location point, the robot determines the sensor location information; the robot locates the WiFi fingerprint location candidate location point, The environment image information locates the candidate location point and the sensor location information is sent to the robot positioning central management system; the robot positioning central management system locates the candidate location point and the environment according to the received WiFi fingerprint. The image information locates the candidate position point and the sensor positioning information, determines the current position of the robot, and sends the determined position to the robot. The present application also provides a robot positioning system.

Description

technical field [0001] The present invention relates to the technical field of robot positioning, in particular to a method and system for robot positioning based on WiFi6 communication. Background technique [0002] In recent years, more and more mobile robots have been applied in various scenarios. In order for a mobile robot to navigate autonomously and perform various tasks, it needs to know its own position and attitude angle very accurately. In the prior art, a single positioning method is used, and the positioning accuracy is low, which cannot meet the needs of various scenarios. Especially in the case of complex environments, the single positioning method in the prior art cannot meet the needs of high-precision positioning. Contents of the invention [0003] In view of the above technical problems, the embodiments of the present application provide a robot positioning method and system to improve positioning accuracy and positioning efficiency. [0004] The posi...
