Embodiment 1

[0067] In this embodiment, the ranging sensor adopts a laser ranging sensor, and the magnetic direction sensor probe adopts a miniature fluxgate sensor.

[0068] like image 3 As shown, a laser ranging sensor 5 , an earphone connector 8 , a motor 9 , a receiver 10 and a speaker 13 are assembled on the front end of the main board 2 . Considering that the motor 9, the receiver 10 and the horn 13 are all magnetic components, which will affect the accuracy of the magnetic sensor 6, the magnetic direction sensor probe 6 is assembled on the rear end of the main board to keep a sufficient distance between them.

[0069] A microphone 14 and a system connector 17 are mounted on the back of the motherboard. The battery 4 is installed in parallel with the mainboard through the battery connector 16 . Braille keys 11 with Braille protrusions are assembled on the keyboard board 3 . The shell 1, the main board 2, and the keyboard board 3 are connected by screws and structural buckles.

Abstract

The invention discloses a portable blind-guiding terminal and a blind-guiding method thereof. The blind-guiding terminal includes: a wireless ranging module, which is used to transmit and receive ranging signals to obtain a distance signal between the blind-guiding terminal and a reflection point, and convert the distance signal Sent to the ranging processing module; the ranging processing module is used to convert the obtained distance signal into an audio signal code stream corresponding to the frequency and sends it to the audio processing module; the audio processing module is used to convert the audio signal code stream It is an audio signal and output through headphones or speakers. The blind guide terminal may also include a fluxgate sensor module and a direction identification processing module for identifying directions, and may also include a positioning module for providing location information. In addition to realizing the obstacle distance detection function realized by ordinary blind-guiding instruments, the present invention can also distinguish the three-dimensional shape and size of the obstacle, and combine the user's real life experience to distinguish the specific object.

Description

technical field [0001] The invention relates to the technical field of portable terminals, in particular to a portable terminal for guiding the blind and a method for guiding the blind. Background technique [0002] Currently, the visually impaired usually use walking sticks to find their way when traveling. Although the walking stick is convenient to use, the detection range is limited and it is inconvenient to carry. More importantly, using the walking stick to find the way will hurt the user's self-esteem. With the development of electronic technology and the popularization of navigation technology, blind guide devices with navigation functions have appeared, such as GPS navigation mobile phones designed for the visually impaired, which can provide users with current location information by voice, but Inherent characteristics such as low GPS accuracy and poor real-time performance affect the popularization and application of this product. [0003] The Chinese patent appl...
