Abstract
The invention discloses a shoe capable of exploring the way and belongs to shoes. A detector is disposed on the shoe. The detector comprises a circuit board, a loudspeaker connected with the circuit board, a power supply powering the circuit board and a switch for controlling on and off of the power supply, and an ultrasonic transmitting head and an ultrasonic receiving head which are mounted on the circuit board. A 120-degree included angle is formed between the ultrasonic transmitting head and the ultrasonic receiving head. A control circuit for converting the signals detected by the ultrasonic transmitting head and the ultrasonic receiving head into voice signals is disposed on the circuit board. The shoe has the advantages that the micro-detector formed by using the ultrasonic principles is disposed in the shoe, detecting effect and exploring distance are increased, and the shoe is convenient to operate and use.
Description
Technical field
The present invention relates to footwear field, specifically a kind of footwear with the function of exploring the way.
Background technology
Common footwear do not possess the function of detection, and blind person is very inconvenient when going out, and hide obstacle.It is to be all generally to adopt crutch to explore the way that blind person goes out, and because crutch can not be oversize, investigative range is very limited, can not bring good Effect on Detecting, to blind person's trip, makes troubles.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the invention provides a kind of footwear with the function of exploring the way, detection range is far away and Effect on Detecting is good, when detecting obstacle, can send voice reminder.
The present invention realizes with following technical scheme: a kind of footwear with the function of exploring the way, a detector is set on footwear, described detector comprises circuit board, the loudspeaker being connected with circuit board, power supply to circuit board power supply, for controlling the switch of on/off, be arranged on ultrasonic wave emitting head and ultrasonic wave Receiver on circuit board, between ultrasonic wave emitting head and ultrasonic wave Receiver, there is the angle of 120 degree; On circuit board, be provided with the control circuit that signal for ultrasonic wave emitting head and ultrasonic wave Receiver are detected converts voice signal to.
The invention has the beneficial effects as follows: utilize ultrasonic listening principle form a micro detector and be arranged in footwear, can improve Effect on Detecting and detection range, easy for operation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is mounting structure schematic diagram of the present invention;
Fig. 2 is ultrasonic wave emitting head and ultrasonic wave Receiver mounting structure schematic diagram;
Fig. 3 is control circuit figure.
In figure: 1, loudspeaker, 2, power supply, 3, circuit board, 4, ultrasonic wave Receiver, 5, ultrasonic wave emitting head, 6, switch.
The specific embodiment
As depicted in figs. 1 and 2, the footwear with the function of exploring the way are the footwear that a detector is set on footwear, described detector comprises circuit board 3, the loudspeaker 1 being connected with circuit board 3, give the power supply 2 of circuit board 3 power supplies, for controlling the switch 6 of on/off, be arranged on ultrasonic wave emitting head 5 and ultrasonic wave Receiver 4 on circuit board 3, between ultrasonic wave emitting head 5 and ultrasonic wave Receiver 4, there is the angle of 120 degree; On circuit board 3, be provided with the control circuit that signal for ultrasonic wave emitting head and ultrasonic wave Receiver are detected converts voice signal to.Ultrasonic wave emitting head and ultrasonic wave Receiver are arranged on respectively the both sides of same casing, and emitting head should become 120' angle with the end face of Receiver.
As shown in Figure 3, control circuit comprises the ultrasonic transmitter that triode VT1, triode VT2 and ultrasonic wave emitting head 5 form; The ultrasonic wave voltage amplifier circuit that triode VT3, triode VT4 and ultrasonic wave Receiver 4 form; The ultrasound detection circuit that tone decoder IC1 and peripheral cell thereof form; The sound circuit that speech chip IC2 and peripheral cell thereof form; Ultrasonic transmitter is connected with ultrasonic wave voltage amplifier circuit, and ultrasonic wave voltage amplifier circuit is connected with tone decoder IC1, and tone decoder IC1 is connected with speech chip IC2.
Described ultrasonic wave emitting head 5 adopts ultrasonic wave emission sensor UCM-40-T, and ultrasonic wave Receiver 4 adopts ultrasonic wave receiving sensor UCM-40-R.Tone decoder IC1 selects LM567 or NE567, NJM567 type phaselocked loop tone decoder, the present embodiment adopts LM567, it is 8 pin flat, plastic encapsulating structures, and its inside is comprised of phase comparator, voltage controlled oscillator, quadrature phase detector device and logic output amplifier etc.Speech chip IC2 selects KD56022, inside contains the speech IC of " reversing, please notes ".A 6V laminated cell or No. 7 dry cell series connection of 4 joints for power acquisition.In order to reduce space, what components and parts were used is SMD components.Be provided with in addition switch 6, the used time can not turned off.
Triode VTl and triode VT2 form direct lotus root and close amplifying circuit, by the feedback generation of piezo-electric crystal in ultrasonic wave emitting head, vibrate.Ultrasonic wave emitting head 5 is both as the resonant element of oscillator, again as ultrasonic wave radiated element.Outwards launch 40kIIz ultrasonic wave.Ultrasonic wave Receiver 4 receives 40kHz ultrasonic signal to carry out after voltage amplification through triode VT3 and triode VT4, through bolcking condenser C2 lotus root, be bonded to tone decoder IC1 again, tone decoder IC1 adopts LM567, when the defeated people's of 3 pin the signal frequency of LM567 is identical with the frequency of oscillation of its internal voltage controlled oscillator, the frequency of oscillation that the capacitor C5 connecing between the resistor R7 being connect by 5,6 pin of LM567 and 6 pin and ground determines its internal voltage controlled oscillator is also during 40kHz, its 8 pin output low levels.When 8 pin output low level, triode VT5 conducting, its emitter stage becomes low level.This low level triggers speech chip IC2, after triode VT6 power amplification, drives loudspeaker to send the warning of " reversing, please notes ".Trigger once, sounding once.
