Abstract
An intelligent infrared guide system for blind people is composed of the infrared broadcast devices arranged at different positions for broadcasting the infrared guide information, the infrared receivers carried by each blind person, and an infrared transcriber for copying relative infrared guide information to each infrared broadcast device.
Description
Technical field:
The present invention relates to the instrument and the information transmission and the photoelectric communication field that help the weakling to walk about, specifically is a kind of blind person's infrared intelligent guidance system.
Background technology:
The blind-guiding device, relatively more direct Chinese patent 00221479 " Leader for blind person " of authorizing as July 4 calendar year 2001, be to be provided with rotatable guidance spheres in the bottom of guide rod, the upper end of guide rod, extend axial guard bar is set, rely on the rolling of guidance spheres and carry out, realize the protection on width and the height simultaneously.Also by the blind person's walking along the street system that forms by coating formula or adhesive type or intelligent sidewalk for visually impaired people, induction type electronic road sign and intelligent-induction formula walking stick.Also useful ultrasound wave echo is navigated, or comes sensing with remote-controled digital coding sound equipment blind person aid device.It as the notification number of on October 22nd, 2003 bulletin 1450525 Chinese patent application " remote-controled digital coding sound equipment helps blind sense finder ", branch group selection and beat switch on the operate wireless of the being help others electrical remote control emitter, control distribute be placed in the people's living environment of receiving aid and article commonly used near signal receiver separately or by combination in any circulation sounding, thereby realize the purpose that helps blind person's sensing, locate and look for something.But to the construction of blind person's apartment nowadays, the guidance system that need have a kind of discriminating direction and room location to differentiate.
Summary of the invention:
The blind person's infrared intelligent guidance system that the object of the present invention is to provide a kind of blind person's of being suitable for apartment to use with discriminating direction and fixed point differentiation.
Purpose of the present invention reaches by following technical solution: native system comprises infrared broadcaster, infrared audio signal reception device and infrared information rerecording device.At the infrared broadcaster of apartment road junction mounting strap discriminating direction pick off, can launch different environment prediction information guide contents with the infrared data form according to people's the direction of motion.The infrared broadcaster of band human body sensor is installed above each guest room doorframe, receives and emission fixed point guide content with the infrared data form.Perhaps rewrite content in the guide information and after editing, import the infrared information rerecording device, transcribe into the infrared broadcaster of band discriminating direction pick off and the infrared broadcaster of band human body sensor in the mode of infrared communication to the erecting bed of infrared broadcaster again.The person of receiving aid holds infrared audio signal reception device in order to the infrared data that receives infrared broadcaster and convert voice to, does not influence other people ground and does not listen to from earphone by the guide indication of sending in the infrared broadcaster.Detect people's process and determine the direction that it is advanced as the infrared broadcaster at certain corridor mouth band discriminating direction pick off, infrared broadcaster just is sent in the information of the environment prediction on its direct of travel to him.Because the infrared audio signal reception device that the person of receiving aid holds is corresponding with its fixed point guest room, when the person of receiving aid arrives this fixed point guest room, the infrared broadcaster of the band human body sensor of door top, guest room can indicate correctly and arrive, promptly in the earphone of this person's of receiving aid infrared audio signal reception device voice output is arranged, and be not have corresponding set point signal output on other doorways, guest room.
The present invention has following beneficial effect:
1. discriminating direction and the environment prediction that the infrared broadcaster of band discriminating direction pick off broadcasts among the present invention as infrared informations such as step, slope, stair, barrier, objective room number positions, is that all infrared audio signal reception devices of blind person can both be received.So that the person of moving in can both understand the inhabitation surrounding.Information passes to blind person's earphone in real time, has avoided sound to disturb, and has promoted the gracefulness of environment.
2. the fixed point guide content of broadcasting for the infrared broadcaster of being with human body sensor has only corresponding infrared audio signal reception device to receive.Be to hear in other words, and be not that the infrared audio signal reception device that fix a point is not responded for other to specified special messenger.Accomplished personalized service to the special messenger.
3. infrared audio signal reception device contains clock, can also give the correct time.
4. the present invention can extend and is used for outdoorly, and corresponding infrared broadcaster is installed on position, road junction on the road and road bar, and the blind person just can walk about easily by infrared audio signal reception device, and can save the laying of sidewalk for visually impaired people, ground.
5. the present invention brings bigger widening can for blind person's range of activity, as supermarket, commercial building, hotel, restaurant, station, is library, hospital, train, boats and ships, the sports ground of blind person's service, has more embodied care and the love of society to the blind person.
6. favourable raising blind person's self-respect, self-confident mentally, can lose walking stick, in life close to the normal person.
7. the present invention utilizes infrared technique, and positioning accuracy can reach 1～2 meter scope, comes highly than the positioning accuracy of tens meters scopes of radio frequency.
8. so high-tech combines with building, coordinates to merge, for social construction provides a kind of new means.
