Abstract
The utility model provides a portable GPS voice guide machine with a radio function, which is provided with a GPS module, a digital voice recording-playback module, an electronic compass module, a radio module and a FLASH memory inside. Under assistance of a person with healthy eyes, GPS data of a frequently walking path of a blind person can be recorded, key places of the walking path of the blind person are prompted by means of digital recording and playback, when the blind person individually walks later on, the recorded GPS data can guide the blind person, the electronic compass module is used for determining directions when the blind person stands still, and the radio is a necessity for the blind person in daily life. The portable GPS voice guide machine has the function of the radio so that the blind person can listen to the radio while being guided.
Description
Affiliated technical field
This utility model relates to a kind of guide machine that utilizes gps signal and guided by voice, and has radio function, and is hand-holdable, also can put into pocket.
Background technology
Several years ago, GPS navigation appears on the automobile, and price at that time is very expensive.Now the price of GPS module constantly reduces, and volume dwindles widely, and the application of built-in gps antenna, make GPS can be technically with cost on finish task into blind man navigation.
Summary of the invention
The utility model proposes a kind of portable guide machine, built-in GPS module, digital speech recording playback module, digital compass module, radio receiver module and FLASH memorizer; Under person of good sense's help, the gps data of the route that can often walk a blind person is noted, and with the mode of digital sound recording the crucial place of blind person's track route is pointed out; The digital compass module is used for determining the orientation when the blind person is static; Radio is indispensable articles for use in the blindman, and this utility model has also attached wireless function, makes after guide, can listen to the radio.
The technical scheme that this utility model adopted is: owing to be blind person's out using, so must be battery-powered, and with the microprocessor control core, with microprocessor is electrically connected the GPS module arranged, digital speech recording playback module, digital compass module, radio receiver module and FLASH memorizer.The route that will go out to walk for the blind person, can lead walking by the person of good sense earlier, the gps antenna of native system receives gps signal, the GPS module demodulates gps data, and record everywhere is gps data down, be stored in the FLASH memorizer in this utility model, place in key, as the turning, can carry out digital recording, the mike pickup analogue voice signal by in the system is converted into digital speech by the AD module again, and store by microprocessor, be stored in the FLASH memorizer in this utility model.Later on when the blind person goes out separately, this utility model just can be compared according to gps data that has recorded and the on-the-spot gps data that receives in real time, and blind person's route is guided, in crucial place, can also carry out the playback prompting with the digital voice data that recorded in the past by the DA module.In when motion, gps system can indicate the direction of all directions of motion easily, but when static, need indicate with digital compass, just can indicate all directions.Radio receiver module is installed in this utility model, is made this utility model using as radio at ordinary times.
The beneficial effects of the utility model are: can be that the blind person goes out to navigate with voice accurately easily; Volume is small and exquisite, and is hand-holdable, also can put into pocket; Can work as radio at ordinary times uses; Cheap.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is function of the present utility model and external form sketch map.Wherein 1 is the antenna of GPS, and 2 is microphone aperture, and 3 is key groups, and 4 is earphone interface, and 5 is switch
Fig. 2 is an enforcement theory diagram of the present utility model.
The specific embodiment
Microprocessor can be selected 8 single-chip microcomputers for use, and key is power saving, for example can use μ W (μ watt) the level single-chip microcomputer of MSP430 series, or the nW of PIC series (nanowatt) level single-chip microcomputer.
The GPS module can be selected GF3SF1613 for use, and selects associated built-in antenna.
Digital speech recording playback module can be selected the ISD4004-08M chip for use, and it collects digital sound recording and is stored among a slice, and sound clarity can be stored 8 minutes speech datas, and is for the voice suggestion of leading, enough.
Consider that present blind person's great majority have had radio, when implementing this utility model, can adopt the kind of band radio receiver module and not with the kind of radio receiver module.The band radio receiver module, function is complete; Be not with radio receiver module, price is low, power saving some.
FLASH can select the 24c256 serial storage for use, and its consumption is big, and low price can be stored the 32K byte data.
More than all modules using method and and the method for attachment of microprocessor all have the known document of full disclosure to be illustrated, can heavily not chat in this manual in the specific implementation with reference to consulting.
