Description
technical field:
this utility model relates to a kind of blind person's voice guiding device based on FPGA.
background technology:
blind person is special social group, and they need the more intelligent navigation Service of exploring the way.But many routing devices explore the way while helping providing, there is the shortcoming that volume is large, be not easy to carry, do not there is sound prompt function yet, cause blind person can not obtain in time the prompting of walking environment, can not hide in time peripheral obstacle.In addition, existing bland person walking stick can not be pointed out the step number between barrier and blind person.
summary of the invention:
the purpose of this utility model is to provide a kind of blind person's voice guiding device based on FPGA.
above-mentioned object realizes by following technical scheme:
blind person's voice guiding device based on FPGA, its composition comprises: walking stick shell, described walking stick outer casing bottom is installed universal rolling wheel, and described walking stick cover top portion connects handheld terminal, and described handheld terminal surface has on and off switch and audio frequency output socket; LED display and one group of step-length amendment button are installed in described walking stick outer surface of outer cover top, solar panel is installed at middle part, and ultrasonic emitting sensor and ultrasound wave receiving sensor, left-hand ultrasound wave receiving sensor and dextrad ultrasound wave receiving sensor are installed in front, bottom; Described walking stick enclosure hollow is also installed control circuit board and electric power controller, integrated FPGA kernel on described control circuit board, described FPGA kernel connects integrated speech synthesizer and amplifying circuit on described control circuit board, described electric power controller connects described solar panel, wherein, described amplifying circuit connects described ultrasound wave receiving sensor, left-hand ultrasound wave receiving sensor and dextrad ultrasound wave receiving sensor, and described speech synthesizer connects described audio frequency output socket.
the described blind person's voice guiding device based on FPGA, described FPGA kernel is also connected with described LED display and step-length amendment button.
the described blind person's voice guiding device based on FPGA, described walking stick enclosure, described electric power controller also connects lithium battery, and described lithium battery connects described FPGA kernel.
the described blind person's voice guiding device based on FPGA, the junction of described walking stick shell and described handheld terminal is curved, and described handheld terminal outer surface also has slipmat, and the end of described handheld terminal is also installed lanyard.
the beneficial effects of the utility model:
1. existing bland person walking stick is set up speech navigation function by this utility model, for blind person provides the distance short range degree of peripheral obstacle and step number.The ultrasonic emitting sensor that obstacle distance is measured and install by walking stick outer casing bottom front speech navigation function chamber sends ultrasound wave, amplifying circuit and ultrasound wave receiving sensor by nuclear control in FPGA receive the ultrasound wave reflecting, by speech synthesizer, the distance measuring by ultrasound is played to blind person again, and revise button inputted average step length by what show on LED display with step-length, can also obtain the step number of this segment distance between blind person and barrier, and step number also can transfer to audio frequency output socket by speech synthesizer, obtain prompting by earphone again.The solar panel of walking stick shell setting provides power supply for these devices, and the on and off switch control opening and closing arranging by handheld terminal, handled easily, this utility model combines distance of obstacle measurement and sound prompt function and original walking stick, has timely acquisition prompting and the accurately effect of prompting.
2. this utility model is provided with universal rolling wheel at walking stick outer casing bottom, blind person need not repeat to mention the action of walking stick repeatedly like this, walking stick can advance by thrust on smooth ground, only need in the time running into out-of-flatness ground, mention walking stick, reduces the use fatigue strength of user.Different directions is determined whether to barrier is only the front of walking stick shell need be turned to this direction, and flexible to operation, prompting accurately, avoids blind person to meet accident.
brief description of the drawings:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is operation principle structured flowcharts that this utility model relates to.
detailed description of the invention:
embodiment 1:
