Abstract
The invention provides a blind crutch with ultrasonic control and sound reminder; an ultrasonic receiving, regulation and control circuit and an ultrasonic regulation and emitting circuit are respectively connected with two I/O ports on one end of a singlechip integrated control circuit; one end of a sound processing circuit unit used for amplifying sound and processing the sound into wired or wireless sound information is connected with the singlechip integrated control circuit with the other end connected with a sound output terminal; the singlechip integrated control circuit is connected with a normal open switch button. An ultrasonic emitting probe and a receiving probe are used for road probing; the road condition information is processed to be sound reminding signals by the singlechip integrated control circuit; the sound reminding signals are outputted to a wired or a wireless earphone worn by the blind man so that the blind crutch brings great convenience to the blind man who uses a crutch to assist walking; the blind crutch with ultrasonic control and sound reminder has the advantages of safety, reliability, high sensitivity, convenient application and being a personalized invention.
Description
Technical field
The present invention relates to the crutch that a kind of blind person uses, a kind of specifically blind-man crutch with ultrasound wave control and voice suggestion.
Background technology
The crutch of selling on the market has various functions now, is intended to auxiliary handicapped people's walking.But, up to now, do not see to have and survey pavement behavior and point out the special-purpose crutch of blind person of blind person's walking to come out with warm phonetic function by range unit.
Summary of the invention
The object of the present invention is to provide a kind of blind-man crutch, can pass through supersonic sounding, range finding and voice suggestion and help blind person's walking with ultrasound wave control and voice suggestion.
Comprise in the technical solution adopted for the present invention to solve the technical problems that ultrasound wave receives and regulating circuit is used to control the ultrasound wave receiving transducer, ultrasound wave conditioning and radiating circuit are used to control the ultrasonic emitting probe, single motor integral control circuit is used to control the overall operation state, and the embodiment that is adopted is:
Ultrasound wave reception and regulating circuit are controlled the ultrasound wave receiving transducer and are received extraneous detection information and be transferred to the processing of single-chip microcomputer integral control circuit under the power turn-on state;
Ultrasound wave conditioning and radiating circuit are controlled the ultrasonic emitting probe and are outwards sent the ultrasound wave that is intended to detection information under the power turn-on state;
Described ultrasound wave receives and transfers the spy circuit to be connected with the IO mouth of single-chip microcomputer integral control circuit respectively with ultrasound wave conditioning and radiating circuit;
Speech processing circuit unit one end that voice can be amplified and be processed into wired or wireless voice messaging connects the single-chip microcomputer integral control circuit, and the other end connects the voice output termination;
The single-chip microcomputer integral control circuit is established lead and is connected the normal open switch button.
The said elements combination all is mounted on the handle inside of crutch, wherein:
Ultrasonic emitting probe and ultrasound wave receiving transducer are positioned at the front end below of handle;
The voice output termination is positioned at the tail end of handle;
The normal open switch button is positioned at below one side of handle.
The on-chip power that is used for work communicates with each element with the handle junction and passes through the normal open switch button in crutch and constitutes the closed-loop path.
Described voice output termination is wired earphone jack or wireless transmit termination.
Concrete operation principle is: when pressing the normal open switch button, produce the sonic oscillation wave source by the single-chip microcomputer integral control circuit and give ultrasound wave conditioning and radiating circuit, give ultrasonic emitting after to processing such as the shaping of sonic oscillation ripple, amplifications by the latter and pop one's head in and launch; Then, run into the ultrasound information that the barrier back reflection is returned by the reception of ultrasound wave receiving transducer, again by amplifying through ultrasound wave reception and modulate circuit, detection, send into the single-chip microcomputer integral control circuit after the processing such as shaping, at last, by the single-chip microcomputer integral control circuit according to emission with return the time difference that ultrasound wave experiences and calculate detection range, it is the distance between crutch and the barrier, and utilization has the single-chip microcomputer (as SPCE061A) of language process function, the range information of surveying is transformed into warm digital speech cue by speech processing circuit, the linguistic information that converts analogue signal to by the DAC circuit unit is sent into the Language Processing circuit unit again, is amplified by the latter and be processed into wired or wireless voice messaging to send on the wired or wireless reception earphone that the blind person wears.
The invention has the beneficial effects as follows: the blind-man crutch of band supersonic sounding and sound prompt device can utilize ultrasound wave road conditions detection system in the crutch and speech processing system to help the blind person rule of thumb distance and measured distance are differentiated traffic information, comprise whether barrier, gully etc. are arranged, alleviate greatly owing to physical handicap cause handicapped, be the contrive equipment of a hommization.
