Description
Technical field
The invention belongs to automatic control system technical field, specifically, relate to a kind of intelligent blind guiding system and blind-guiding method.
Background technology
Blind person is a special life colony, because vision is limited, inconvenient to watch, to the more puzzlement that the life of blind person brings.In life, blind person often by crutch walking, examines the barrier on crutch identification road, but existing crutch only there is conventional crutch and function, not intelligent.The blind person also had is by guide instrument guides such as seeing-eye dogs, but seeing-eye dog need through strict training, and trained seeing-eye dog still deposits kind of a numerous uncertain factor.Intellectual technology is growing, how to utilize the life that intellectual technology is blind person to provide facility also significant.
Summary of the invention
The object of the present invention is to provide a kind of intelligent blind guiding system and blind-guiding method.
Technical scheme of the present invention is: a kind of intelligent blind guiding system, intelligent blind guiding system comprises the radio-frequency (RF) tag being arranged at guide recognition system on blind-guide brick and being arranged in public environment, radio-frequency (RF) tag is arranged on the sidewalk for visually impaired people of every bar road, guide recognition system comprises controller, radio-frequency recognition system, voice-transmission system, information transmission system, detection system; Controller is connected with voice-transmission system, and voice-transmission system is also connected to phonetic incepting end; Controller is connected with detection system through information transmission system, and detection system comprises obstacle detection system and road surface height detection system, and obstacle detection system is connected with controller respectively through information transmission system with road surface height detection system; Radio-frequency recognition system gathers the radio frequency label information on sidewalk for visually impaired people, and radio-frequency recognition system is connected with controller through information transmission system.
Preferably: voice-transmission system is wireless speech transmission system, and this blind guiding system also comprises wireless headset, carries out wireless information transfer between wireless speech transmission system and wireless headset.
The blind-guiding method of intelligent blind guiding system, comprises the following steps:
(1) intelligent blind guiding system sets barrier wireless distances and road surface height danger coefficient in advance;
(2) whether obstacle detection system detection traveling front exists barrier, if barrier detected in the risk distance of setting, detection system communicates information to controller by information transmission system, and controller controls voice-transmission system and makes danger signal prompting;
(3) whether obstacle detection system detection traveling front exists fluctuating road surface, if fluctuating pavement-height is within the scope of the height danger coefficient of setting, detection system communicates information to controller by information transmission system, and controller controls voice-transmission system and makes danger signal prompting;
(4) radio-frequency recognition system gathers the information of radio-frequency (RF) tag on road, obtains road information, information is delivered to controller through information transmission system;
(5) road information is delivered to wireless headset through voice-transmission system by controller, and blind person obtains road information.
The invention has the beneficial effects as follows: this intelligent blind guiding system can detect barrier, before blind person arrives barrier, make voice message to blind person; Whether this intelligent blind guiding system can also detect road surface evenness, if hollow bottom surface or up/down steps road surface detected, makes voice message in advance to blind person.Adopt wireless speech transmission system that system structure can be made simpler, be convenient to blind person and use.This system can improve the convenience of blind person's trip greatly.This intelligent blind guiding system gathers road information by the radio-frequency (RF) tag be arranged on road, passes to user, facilitates user to understand walked road information, avoids blind person to get lost.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Detailed description of the invention
