Description

Intelligent guiding walking stick for blind person
Technical field:
The invention belongs to electronic technology field, is related to a kind of for detecting preceding object thing and pointing out The intelligent blind use cane of the ultrasonic ranging formula of general direction and distance, particularly a kind of intelligent guiding walking stick for blind person Preparation method.
Technical background:
Existing blind-guiding stick is simple crutch, can only detect preceding object by touching, is used When highly inconvenient and detection range and limited accuracy, go on a journey alone to blind person and bring very big Inconvenience;Although at present country's blind person's articles for use are significantly increased in type and quantity, at some High-end articles for use are such as:Ultrasound wave explores the way the aspects such as instrument almost or blank, and same kind of products at abroad Have the shortcomings that species is single, and its fancy price is not that common people can bear, very Hardly possible is popularized in blind person.Sum up, existing some blind seeking apparatuses its investigative range, Defect is there is in degree of accuracy, comfortableness and practicality;Traditional crutch is existing and uses More than one thousand years, but never have breakthrough in function and technology.With present blind person's articles for use city Field constantly expands, and we have reason to research and develop a kind of new spy intelligent easy to use for them Road instrument.
The content of the invention:
The purpose of the present invention is that the shortcoming for overcoming prior art to exist, and seeks to design a kind of general Ultrasonic sensor in combination with single-chip microcomputer and speech chip, automatic control survey and barrier away from From collection information control voice chip Jing after single-chip microcomputer process sends the device of response prompt tone.
For achieving the above object, the circuit control part of intelligent guiding walking stick for blind person of the present invention mainly has ultrasound Ripple transmitting, receiving circuit, signal processing circuit, telemetry circuit and the part of voice warning circuit four Composition;By being reflected and shape by barrier to the ultrasonic pulse that ultrasonic transmitter is launched Into reflected impulse be acquired, by the signal for being gathered by the two poles of the earth amplify, audio coding lock Single-chip microcomputer is sent into after circuitry phase, is clocked by single-chip microcomputer and distance is calculated, single-chip microcomputer is by basis Calculating result drives voice warning circuit to report corresponding data.
The present invention agent structure include ultrasonic transmitter, ultrasonic receiver, stick body, The parts such as control board, power supply, switch, stick handle and rubber bodies, cylindricality hollow type crutch Body top horizontal turn is formed with stick handle, and bottom is connected and is formed with soft rubber bodies, in stick body and Stick handle joint is formed with the on and off switch for being easy to stick-holding hand to press;Stick body adopts rigid material Inner chamber is made for empty body formula, be provided with inner chamber control board, power supply and ultrasonic emitting with Receive device, be electrically connected by electrical principles, realize integral control function;In stick body lower end The ultrasonic receiver that upper and lower arrangement is formed with to corresponding direction is turned with stick handle in rubber bodies top With emitter, and the unimpeded function of its ultrasound wave is realized in structure;Control board according to Routinely technique is electrically connected to be connected into and is easy to be installed in crutch body and even its control circuit structural principle Logical plank frame, realizes safe and reliable and stable function.
The transmitting of signal handled by the control circuit of the present invention is with reception by two panels ultrasonic sensor Realize, single-chip microcomputer provides clock pulses for the sensor for launching ultrasound wave, ultrasonic transmitter Tranmitting frequency is 40KHz, and transmitting ultrasound wave, Jing in certain angle scope (about 9 degree) The signal processing electricity that reflected signal gives next stage is gathered by ultrasonic receiver after barrier reflection Road.This partial circuit is mainly made up of two-stage high-frequency signal amplifying circuit and a phaselocked loop, letter Export a stable high level signal and give single-chip microcomputer INTO ports after number processing.Single-chip microcomputer is remembered Under from ultrasound wave is launched to signal t this period is received, calculate between barrier apart from s; Produce interrupt requests and call responder to control playback circuit playback, after interrupt routine has been performed Enter back into mastery routine and start the cycle over detection;Blind person can listen to prompt tone by earphone.
Intelligent guiding walking stick for blind person of the present invention compared with traditional crutch technology, its function is new, practical, Circuit is simple, good stability, measurement range are big, high precision, for the spy such as blind person and amblyopia people The different consumer group, with certain market prospect.
Description of the drawings:
Fig. 1 is the overall structure principle schematic of the present invention.
Fig. 2 is the test control circuit principle schematic diagram. of the present invention.
Specific embodiment:
Below by embodiment and combine accompanying drawing the present invention is described in further details:
Embodiment 1:
The agent structure of the present embodiment includes ultrasonic transmitter 1, ultrasonic receiver 2, crutch The parts such as body 3, control board 4, power supply 5, switch 6, stick handle 7 and rubber bodies 8, The top horizontal turn of cylindricality hollow type stick body 3 is formed with stick handle 7, and bottom is connected and is formed with software Formula rubber bodies 18, the electricity for being easy to stick-holding hand to press is formed with stick body 3 and the joint of stick handle 7 Source switch 6;Stick body 3 adopts rigid material to make inner chamber for empty body formula, is provided with inner chamber Control board 4, power supply 5 and ultrasonic transmitter 1 and accepter 2, are electrically connected by electrical principles It is logical, realize integral control function;Turn with stick handle on the top of rubber bodies 8 of the lower end of stick body 3 The ultrasonic receiver 1 and emitter 2 of upper and lower arrangement are formed with to corresponding direction, and in knot The unimpeded function of its ultrasound wave is realized on structure;Control board 4 is according to its control circuit structure Routinely technique is electrically connected to be connected into and is easy to install and the board-like knot for connecting in the stick body 3 principle Structure, realizes safe and reliable and stable function.
