Abstract
The utility model discloses a pathfinding coat for blind persons and relates to the field of clothes. The coat is characterized in that a detector is arranged on the coat and comprises a circuit board, a loudspeaker connected with the circuit board, a power supply for supplying power for the circuit board, a switch used for controlling the on and off of the power supply, an ultrasonic transmitting head and an ultrasonic receiving head, wherein the ultrasonic transmitting head and the ultrasonic receiving head are mounted on the circuit board, and the included angle between the ultrasonic transmitting head and the ultrasonic receiving head is 120 degrees; and a control circuit used for converting signals detected by the ultrasonic transmitting head and the ultrasonic receiving head into voice signals is arranged on the circuit board. The pathfinding coat for blind persons has the advantages that a minitype detector is constituted based on the ultrasonic detection principle and is arranged in the coat, so that the detection effect improved, the detection distance can be increased, and the operation and the use are convenient.
Description
Technical field
The utility model relates to garment industry, specifically is a kind of blind person clothes of exploring the way.
Background technology
Common clothes do not possess the function of detection, and the blind person is very inconvenient when going out, and hide obstacle.It is generally all to be to adopt crutch to explore the way that the blind person goes out, because crutch can not be oversize, investigative range is very limited, can not bring good Effect on Detecting, makes troubles to blind person's trip.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of blind person the clothes of exploring the way, and detection range is far away and Effect on Detecting is good, when detecting obstacle, can send voice reminder.
The utility model is realized with following technical scheme: a kind of blind person clothes of exploring the way; A detector is set on clothes, and described detector comprises circuit board, the loudspeaker that is connected with circuit board; Power supply to the circuit board power supply; Be used to control the switch of on/off, the ultrasonic emitting head and the ultrasonic wave that are installed on the circuit board receive head, and ultrasonic emitting head and ultrasonic wave receive the angle that has 120 degree between the head; Circuit board is provided with and is used for ultrasonic emitting head and ultrasonic wave are received the control circuit that a signal that detects converts voice signal to.
The beneficial effect of the utility model is: utilizes the ultrasonic listening principle to form a micro detector and be arranged in the clothes, can improve Effect on Detecting and detection range, and easy for operation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the utility model mounting structure sketch map;
Fig. 2 is that ultrasonic emitting head and ultrasonic wave receive a mounting structure sketch map;
Fig. 3 is control circuit figure.
Among the figure: 1, loudspeaker, 2, power supply, 3, circuit board, 4, ultrasonic wave receives head, 5, the ultrasonic emitting head, 6, switch.
The specific embodiment
As depicted in figs. 1 and 2; Blind person's clothes of exploring the way are clothes that a detector is set on clothes, and described detector comprises circuit board 3, the loudspeaker 1 that is connected with circuit board 3; Give the power supply 2 of circuit board 3 power supplies; Be used to control the switch 6 of on/off, be installed in ultrasonic emitting 5 and ultrasonic wave on the circuit board 3 and receive 4, ultrasonic emitting 5 and ultrasonic wave receive an angle that has 120 degree between 4; Circuit board 3 is provided with and is used for ultrasonic emitting head and ultrasonic wave are received the control circuit that a signal that detects converts voice signal to.Ultrasonic emitting head and ultrasonic wave receive the both sides that head is installed in same casing respectively, and emitting head should become the 120' angle with the end face that receives head.
As shown in Figure 3, control circuit comprises the ultrasonic transmitter of triode VT1, triode VT2 and ultrasonic emitting 5 composition; Triode VT3, triode VT4 and ultrasonic wave receive a ultrasonic wave voltage amplifier circuit of 4 compositions; The Ultrasonic Detection circuit that tone decoder IC1 and peripheral cell thereof are formed; The sound circuit that speech chip IC2 and peripheral cell thereof are formed; Ultrasonic transmitter is connected with the ultrasonic wave voltage amplifier circuit, and the ultrasonic wave voltage amplifier circuit is connected with tone decoder IC1, and tone decoder IC1 is connected with speech chip IC2.
Described ultrasonic emitting 5 an employing ultrasonic emitting sensor UCM-40-T, ultrasonic wave receives 4 an employing ultrasonic wave receiving sensor UCM-40-R.Tone decoder IC1 selects LM567 or NE567, NJM567 type phaselocked loop tone decoder for use; Present embodiment adopts LM567; It is 8 pin flat, plastic encapsulating structures, and its inside is made up of phase comparator, voltage controlled oscillator, quadrature phase detector device and logic output amplifier etc.Speech chip IC2 selects KD56022 for use, in contain the speech IC of " reversing, please note ".Power supply adopts a 6V laminated cell or No. 7 dry cell series connection of 4 joints.In order to reduce the space, what components and parts were used is the paster components and parts.Be provided with switch 6 in addition, the time spent can not turn off it.
Triode VTl and triode VT2 form direct lotus root and close amplifying circuit, through the feedback generation vibration of piezo-electric crystal in the ultrasonic emitting head.Ultrasonic emitting 5 is both as the resonant element of oscillator, again as the ultrasonic emitting element.Outwards launch the 40kIIz ultrasonic wave.Ultrasonic wave receives 4 and receives the 40kHz ultrasonic signal after triode VT3 and triode VT4 carry out voltage amplification; Be bonded to tone decoder IC1 through bolcking condenser C2 lotus root again; Tone decoder IC1 adopts LM567; When the frequency of oscillation of the defeated people's of 3 pin of LM567 signal frequency and its internal voltage controlled oscillator is identical; The frequency of oscillation of its internal voltage controlled oscillator of capacitor C5 decision that is connect between the resistor R 7 that is promptly connect by 5,6 pin of LM567 and 6 pin and the ground is also during 40kHz, its 8 pin output low levels.When 8 pin output low levels, triode VT5 conducting, its emitter stage becomes low level.This low level triggers speech chip IC2, after triode VT6 power amplification, drives the warning that loudspeaker sends " reversing please notes ".Trigger once, sounding once.
