Embodiment 1

[0055] figure 1 A preferred embodiment of the direction generation method in the field of indoor wireless navigation for the blind is given. In this embodiment, the navigation system on which the direction generation method of the present invention relies includes at least a designated target location and location information marking subsystem, a location tracking and planning subsystem, and a direction guidance subsystem.

[0056] The direction guidance subsystem is a wearable vibration-tactile interactive guidance device, which at least includes a single-chip microcomputer, a geomagnetic sensor, and a direction guidance device, wherein the direction guidance device is a wearable collar; the single-chip microcomputer and the geomagnetic sensor are arranged on the wearable collar; The collar is worn on the neck of the blind person, and 8 vibration motors are evenly installed on the circle where the collar is located, numbered as vibration motor 0-vibration motor 7; the center ...

Embodiment 2

[0073] figure 2 A preferred embodiment of the direction generation method of the present invention in the field of warehouse robots is given. In this embodiment, the navigation system on which the direction generation method of the present invention relies includes at least a designated target location and location information marking subsystem, a location tracking and planning subsystem, and a direction guidance subsystem.

[0074] The direction guiding subsystem at least includes a single chip microcomputer, a geomagnetic sensor, and a direction guiding device, wherein the direction guiding device is a steering device. The direction guidance subsystem is integrated on the storage robot. After the single-chip microcomputer obtains the running direction of the robot, it outputs to the steering device, and the steering device controls the robot to turn in one of 8 directions; the 8 directions are radiated at intervals of 45° according to the geographical environment. Evenly d...

Abstract

The invention provides an indoor wireless navigation direction generation method, which can generate 8 kinds of travel directions, and uses a geomagnetic sensor for direction correction. The indoor wireless navigation direction generation method of the present invention can be applied to the field of indoor navigation for the blind, and meets the needs of blind people who are not very accurate. The navigation direction requirements can also be applied to the field of storage robots, so that the storage robots have flexible movement directions and greatly reduce costs.

Description

technical field [0001] The invention relates to a method for generating indoor wireless navigation directions. Background technique [0002] In the field of indoor navigation for the blind, the current application is the navigation car guidance device that uses electronic tags to store the position information and direction information of the guide sign. The angle deviation between the current direction and the target path is obtained, and then the angle of travel adjustment is given. However, since the walking blind cannot distinguish the precise corner value, this navigation method is difficult to apply to the blind. [0003] The patent with the publication number CN106949890A discloses an indoor wireless navigation system suitable for walking of the blind. The system prompts the direction information of the blind through motor vibration. The wearable interactive device includes a single chip microcomputer and at least one directional collar. The indoor wireless navigati...
