Ultrasonic waves are used for detecting a barrier, and a voice module is used for reminding, so that danger can be greatly reduced, and the safety coefficient is enhanced; when a blind person comes across the barrier, rotation is driven by a motor for applying force to the blind person, and the blind person is guided to advance safely; an advancing route instruction can be sent to the blind person after positioning through a GPS module, and then the blind person is guided to a safe route; position information can be sent to a family member in the form of a short message through a GSM module so that the family member can grasp the position information of the blind person at any time; the system is further provided with a night safety indicator light and music for reminding passersby to avoid the blind person to prevent collision; the system has a one-key emergency call function and sends out a sound-light alarm in an emergency to remind surrounding people of rescue; in the emergency, the position information and pre-written short message content can be sent to a customized mobile phone number in a short message so that the family member can conduct rescue in time.
Description
Technical field
The present invention relates to apparatus for guiding blind field, particularly relate to a kind of intelligent blind guiding system.
Background technology
Blind person is a special colony in the middle of disabled person, and they lose due to congenital or posteriori physiological defect
Lose visual information, but visual information has been the mankind obtains the main source of knowledge and experience, therefore, blind person
In daily life with safely travel aspect by the biggest restriction.In actual life, most blind person is
Being to assist walking, this blind man's stick to be a common stock by common blind man's stick, it can only detect
The barrier of local, also exists too many deficiency.Although seeing-eye dog can assist to guide blind person to advance, but deposits
In the shortcoming that cycle of training and laundering period are long, relatively costly, this also makes the utilization rate of seeing-eye dog the highest.
In order to assist blind safety to advance, improving their quality of life, countries in the world are carrying out electricity always
The development of sub-blind guiding system, the electronic blind-guiding system being currently, there are has ultrasonic blind guiding instrument, mobile machine
People, Wearable apparatus for guiding blind and guiding type walking stick.
Ultrasonic blind guiding instrument is to position in the way of launching ultrasonic wave and receiving barrier reflection echo, with
Radar system is similar to, and it can obtain the information of barrier from the echo received.Ultrasonic blind guiding instrument one
As be made up of transducer (probe), signal processor (electronic box) and information follower three part.Ultrasonic wave
The defect of apparatus for guiding blind is that user needs constantly to be scanned detection action when advancing, and after finding barrier,
Have to pass through additional measurement and just can know that its size, therefore reduce the speed of traveling.Further, ultrasonic wave is not
The obstacles such as pit can be detected, its propagation also can by diffraction, scatter and absorb and affected so that ultrasonic
The problem that ripple apparatus for guiding blind exists missing inspection dead zone information.
Mobile robot is to have multiple sensor, powerful calculating ability and highly intelligent Obstacle avoidance
The robot of system (OAS), its intelligence degree is higher, can carry out autonomous in complex environment
Navigation, along with the design of human-machine interface module is with perfect, can be used for guide application.Based on mobile machine
The apparatus for guiding blind of people's technology, functionally improves a lot than ultrasonic blind guiding instrument.Such as, Rentschle researches and develops
Action accessory VA-PAMAID, can correct avoiding obstacles.Although mobile robot compares ultrasonic blind guiding
Instrument function is more perfect, more intelligent, but its hardware and development cost are at a relatively high.And its volume is huge
Greatly, structure is the most complicated, cannot be carried out mobile on slope and stair, make it in action scope with in landform
It is very limited, is not the most widely used.
Wearable apparatus for guiding blind is directly to be worn by blind-guide device, and blind person is by simple guide voice message
It safely travel.American university robot development in laboratory belt type action accessory, this accessory is in reality
Border application can make blind person's avoiding obstacles by the way of guiding, accept to hide as semi-passive using blind person
The mobile instrument of obstacle avoidance thing order.Or to send out depicted the landform of blind person region by ultrasonic wave after
The modes such as sound make it understand and judge surrounding environment.Although Wearable apparatus for guiding blind side more flexible than mobile robot
Just, but this blind-guide device screws on blind person, and its heavier-weight is relatively costly, and
The psychological sense of security and dependence feeling cannot be provided to blind person.
Guiding type stick is to install at the handle portion of walking stick to have the microcomputer of control action, at walking stick
Diverse location special detection sensor is installed, the lower end of walking stick is equipped with the movable fixture of guide wheel, at present
Already present this type machine is mainly the Guide-Cane of Borenstein.The essence of this electronic blindman guiding instrument is
The dynamical system of mobile robot is unloaded, retains sensing and the control part of its intelligence sensing.Although leading
Draw formula walking stick and can make up ultrasonic blind guiding instrument, mobile robot and the shortcoming of Wearable apparatus for guiding blind, be mesh
Before relatively preferable a kind of electronics blind-guide device, but guiding type stick still exist volume huger,
Not readily portable shortcoming, and its is relatively costly, is not easy to popularization and application.
In usual life, the information of people more than 80% is obtained by vision, for using eye
For eyeball carrys out the blind person of captured information, they freely cannot walk as ordinary person, such as, walk often can go out
Now collide with barrier, lost etc. phenomenon, even can jeopardize life time serious.Therefore, giving birth to
Live and encounter the biggest difficulty in work.Along with economic development, scientific and technological progress and social civilization level not
Disconnected raising, the trip problem of this specific group is increasingly by concern and the attention of countries in the world.In order to carry
The high social care degree to them and relief level, develop more hommization and be more suitable for blind person path
The aid of induction has important practical value and social reality meaning.
