Abstract
The utility model discloses a blindman guide stick, which comprises a blindman guide stick body. The blindman guide stick body is provided with a directional handle and a road condition detection system. The road condition detection system comprises a singlechip, distance sensors, a speed sensor ad a sound producing device, wherein the distance sensors and the speed sensor are connected with the input end of the singchip, and the sound producing device is connected with the output end of the singlechip. The blindman guide stick disclosed by the utility model can be used for helping a blindman to detect road conditions ahead and inform the blindman in the manner of sound, especially, a classified prompt can be performed on different road conditions, so that the blindman makes corresponding measures in advance, and accidents are effectively prevented.
Description
Technical field
This utility model relates to a kind of guide instrument, relates in particular to a kind of blind guiding bar that traffic information is converted into acoustic information.
Background technology
Blind guiding bar is blind person's a guide instrument commonly used, and still, present blind guiding bar is judged road conditions by touch feeling, can not be with concrete traffic information classified prompt.
The utility model content
The technical problem that this utility model will solve provides a kind of blind guiding bar; Can assist the blind person to survey the road conditions in the place ahead and inform the blind person with the form of sound; Especially can carry out classified prompt to different road conditions, make the blind person make Corresponding Countermeasures in advance, effectively avoid unexpected and take place.
To achieve these goals; The technical scheme that this utility model is taked is: a kind of blind guiding bar; Comprise the blind guiding bar body; Directed handle and road conditions detection system are set, the range sensor that this road conditions detection system comprises single-chip microcomputer, link to each other with the single-chip microcomputer input and velocity sensor and the pronunciation device that links to each other with the single-chip microcomputer outfan on the said blind guiding bar body.
As a kind of optimal technical scheme of this utility model, said range sensor and velocity sensor are arranged on the offside of said directed handle.
As a kind of optimal technical scheme of this utility model, said range sensor is two, towards be respectively oblique down and level forward.
As a kind of optimal technical scheme of this utility model, said velocity sensor is one, and it is oriented level forward.
As a kind of optimal technical scheme of this utility model, said pronunciation device is a bluetooth earphone.
Adopt the beneficial effect that technique scheme produced to be: this utility model can be assisted the blind person to survey the road conditions in the place ahead and informed the blind person with the form of sound; Especially can carry out classified prompt to different road conditions; Make the blind person make Corresponding Countermeasures in advance, effectively avoid unexpected and take place.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Fig. 2 is the fundamental diagram of this utility model.
Among the figure: 1, blind guiding bar body 2, directed handle 3, single-chip microcomputer 4, range sensor 5, velocity sensor 6, pronunciation device.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done further detailed explanation.
Referring to accompanying drawing; Comprise blind guiding bar body 1 in the structure of a specific embodiment of this utility model, directed handle 2 and road conditions detection system are set on the blind guiding bar body 1, the range sensor 4 that this road conditions detection system comprises single-chip microcomputer 3, link to each other with single-chip microcomputer 3 inputs and velocity sensor 5 and the pronunciation device 6 that links to each other with single-chip microcomputer 3 outfans; Range sensor 4 and velocity sensor 5 are arranged on the offside of directed handle 2; Range sensor 4 is two, towards be respectively oblique down and level forward, velocity sensor 5 is one; Be oriented level forward, pronunciation device 6 is a bluetooth earphone.
The operation principle of this utility model is: directed handle 2 be used for confirming and the probe of keep at a distance pick off 4 and velocity sensor 5 towards; This utility model can be assisted the blind person to survey the road conditions in the place ahead and informed the blind person with the form of sound; Especially can carry out classified prompt to different road conditions, specifically, velocity sensor 5 is used to detect rapid movement objects such as vehicle; Level forward towards range sensor 4 be used to detect barriers such as house, trees; Oblique down towards range sensor 4 be used to detect dell, inspection shaft depression road surface, above-mentioned detection information is reached single-chip microcomputer 3 carries out analyzing and processing and converts acoustical signal into, points out the blind person traffic information through pronunciation device 6 playing alert tones; Make the blind person make Corresponding Countermeasures in advance, effectively avoid unexpected and take place.
Foregoing description only proposes as the enforceable technical scheme of this utility model, not as the single restrictive condition to its technical scheme itself.
