Description
Technical field
The present invention relates to a kind of blind-guide device, relate in particular to a kind of intelligent blind-guiding device car based on infrared electronic technology.
Background technology
Blind person's independent ambulation generally needs the assistance of blind guide, traditional method is to utilize blind-guiding stick or training seeing-eye dog, walking stick guide is simple and convenient, cost is low, can help blind person to find that 0.5 meter with interior barrier, but can not find barrier and aerial outstanding barrier more a little further, also None-identified traffic signs, reliability is not high, easily ignores some barriers, and seeing-eye dog has certain intelligence, but cultivation cycle is long, cost is high, therefore Low-cost, and functional strong guide vehicle becomes focus.
Summary of the invention
Object of the present invention is just to provide in order to address the above problem a kind of compact conformation, the intelligent guide vehicle based on infrared electronic technology with low cost.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The present invention includes car body, road condition monitoring probe, survey barrier probe, voice prompting device, single-chip microcomputer, microprocessor, drive circuit, left and right wheels motor and decoder, in the front portion of car body, be provided with and survey barrier probe and First look sensor, road condition monitoring probe is installed below car body, described survey barrier probe is connected with the input of described microprocessor respectively with the outfan of road condition monitoring probe, the outfan of described First look sensor is connected with the input of described microprocessor, the outfan of described microprocessor is connected with the input of described voice prompting device, described microprocessor is connected with described microcontroller serial port, the outfan of described single-chip microcomputer is connected with the input of described drive circuit, the outfan of described drive circuit is connected with described left and right wheels input end of motor, described left and right wheels motor output end is connected with the input of described decoder, the outfan of described decoder is connected with the input of described microprocessor.
Particularly, described road condition monitoring probe comprises the first infrared sensor and the second vision sensor.
Further, described survey barrier probe comprises the second infrared sensor and ultrasonic sensor.
As preferentially, described guide vehicle also comprises hand-held control panel, and described hand-held control panel is connected with described single-chip microcomputer wireless telecommunications.
Beneficial effect of the present invention is:
The present invention can adopt the mode of multiple sensors combination, improved accuracy and the stability of guide vehicle, and cost is low, compact conformation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, the present invention includes car body, road condition monitoring probe, survey barrier probe, voice prompting device, single-chip microcomputer, microprocessor, drive circuit, left and right wheels motor and decoder, in the front portion of car body, be provided with and survey barrier probe and First look sensor, road condition monitoring probe is installed below car body, described survey barrier probe is connected with the input of described microprocessor respectively with the outfan of road condition monitoring probe, the outfan of described First look sensor is connected with the input of described microprocessor, the outfan of described microprocessor is connected with the input of described voice prompting device, described microprocessor is connected with described microcontroller serial port, the outfan of described single-chip microcomputer is connected with the input of described drive circuit, the outfan of described drive circuit is connected with described left and right wheels input end of motor, described left and right wheels motor output end is connected with the input of described decoder, the outfan of described decoder is connected with the input of described microprocessor.First look sensor also can Identification display traffic lights judgement, by microprocessor, undertaken after date processing, be sent to after single-chip microcomputer, the motion that the signal that microprocessor is sent converts a series of driving signals to and go to control dolly left and right wheels, realizes detection and the processing of all kinds of road informations.
As shown in Figure 1, road condition monitoring probe comprises the first infrared sensor and the second vision sensor, in order to provide walking along the street convenient to blind person, in urban road, be often provided with sidewalk for visually impaired people, in order to wake up mouth, remind pedestrian to note dodging friend blind person, the blind way brick of building sidewalk for visually impaired people is yellow mostly, with the ordinary people trade shape on side
Become obvious colour contrast, because dark ordinary people trade is different to the reflex strength of infrared light with light sidewalk for visually impaired people, therefore, once the guide vehicle on sidewalk for visually impaired people has departed from sidewalk for visually impaired people, the first infrared sensor receives the reflective infrared light intensity that road reflection returns and will have greatly changed, thereby judgement in time, the second vision sensor also can further be identified zebra crossing, makes blind person can further understand road conditions and position.Survey barrier probe and comprise the second infrared sensor and ultrasonic sensor, the finding range of ultrasonic sensor is generally between 30-300 rice, an obstacle object if the direction of advance of guide vehicle is closely scurried out suddenly, likely can cause ultrasonic sensor range finding error, and infrared sensor can be surveyed the barrier in short range preferably, adopt these two kinds of sensors to measure together and can realize complementation.Described guide vehicle also comprises hand-held control panel, and hand-held control panel is connected with single-chip microcomputer wireless telecommunications, can realize manual control and automatically between control, mutually switch.
