Description
Technical field
The utility model relates to a kind of compass, particularly the electronic speech compass.
Background technology
Compass is an important navigational tool.Early stage compass mainly is pin type compass or compass compass, and the compass of these two kinds of forms is because structure is limit, and volume adopts the mode of mutual mechanical connection than big and element, thereby has significant limitation on using.Development along with the compass technology, digital compass is the pin type compass or the compass compass of replace old gradually, because digital compass adopts all solid state element, without any moving-member, so have characteristics such as volume is little, highly sensitive, shockproof properties is good, easy to use, can also be connected with other electronic systems simply.But existing electronic type compass mainly is digital, and still there is certain limitation in this compass on using, can't use as the blind person, can't use at night, when there is obstacle in sight line, can't use etc.
Summary of the invention
The purpose of this utility model is to overcome the applied defect that above-mentioned existing electronic type compass exists, and a kind of electronic speech compass is provided.
The technical solution of the utility model is: the electronic speech compass, comprise digital compass sensor PNJ11096, microprocessor EM78P468N, reach the signal output apparatus that connects microprocessor, it is characterized in that, described signal output apparatus is voice broadcasting system EMS57300, and this voice broadcasting system EMS57300 connects loudspeaker by the voice signal amplifying circuit; The speech selection switch connects and control voice broadcasting system EMS57300 reaches the Chinese, English is reported alternative; One function switch connects and control microprocessor EM78P468N, with the duty that realizes that they are different.
Be to realize perception of sound and visually-perceptible economic benefits and social benefits fruit, described signal output apparatus also comprises a light emitting diode or a liquid crystal display systems by function switch control that is set up in parallel with voice broadcasting system EMS57300.
The digital compass sensor carries out logic control and mathematical operation through microprocessor, and acquisition process is angled, provides digital display interface and voice to broadcast circuit interface simultaneously.Because this electronic speech compass has increased sound circuit on the basis of digital compass, can amplify by signal and drive the loudspeaker sounding, open the speech selection switch when therefore using, press function ammonium button, the magnetic strength of digital compass sensor is with regard to signal process microprocessor principle logic control and mathematical operation, acquisition angles is handled, start the voice broadcast Circuits System and quote the orientation angles of motion automatically, start the display circuit system simultaneously, the corresponding orientation angle of voice broadcast is presented on the display screen.
The beneficial effects of the utility model are:
The electronic speech compass adopts the total solids element, volume is little, highly sensitive, shockproof properties is good, interference is little, use the DC1.5-6V power supply all can work, the speech selection switch can select Chinese or English to report arbitrarily, by function key operation, can select to quit work, the orientation angles numeral shows, language is reported with numeral and shown simultaneously.This novel electron voice compass has not only replaced traditional compass compass with good performance, overcome and disturbed and shockproof problem, solved diopter bad conditions such as night and weather extremes, abominable geographical environment simultaneously and judged the problem in orientation down, can be widely used on vehicle, boats and ships, field work equipment, tourism supplies, the blind walking-aid instrument and army's night operations action, blind person discern in the direction teaching and use.As be applied to: the digital compass in the automobile, the hand-held electronic compass, the compass in the mobile phone, traffic detects, the detection of ferromagnetic material, magnetic survey, blind person's teaching and walk help etc.
Description of drawings
