Description
Technical field
The utility model relates to the blind person with the induction bracelet, belongs to electronic technology field.
Background technology
The blind person goes out to run into very burden in daily life, and along with the raising of Chinese economic development and society ﹠ culture's attainment, society is also more and more higher to the degree of concern of disadvantaged group.How to ensure the Ms's of society's trip at night safety, avoiding accident is to demand problem to be solved urgently.
Summary of the invention
The utility model is at the proposition of above problem, and the development blind person is with responding to bracelet.
The utility model comprises bracelet and induction installation, it is characterized in that: induction installation is set on the bracelet.Induction installation comprises the ultrasonic wave receiving transducer, ultrasound transmitting transducer, bracelet and phonetic alarm device; The ultrasonic wave receiving transducer connects receiving circuit, and receiving circuit connects single-chip microcomputer; Ultrasound transmitting transducer connects radiating circuit, and radiating circuit connects single-chip microcomputer; Phonetic alarm device connects single-chip microcomputer, and control circuit connects single-chip microcomputer, provides the power circuit of single-chip microcomputer work to connect single-chip microcomputer.
Warning device is speech chip.
Single-chip microcomputer connects external power supply.Bracelet is hollow structure.
Principle of the present invention and beneficial effect: the ultrasonic wave that ultrasound transmitting transducer sends is propagated to run in air and is received by the ultrasonic wave receiving transducer after barrier reflects, measure ultrasonic wave and just can obtain the distance of barrier from the time that is transmitted into the reception needs according to formula S=0.5vt, v is the spread speed of ultrasonic wave in aloft, t is that ultrasonic wave is from being transmitted into the reception required time, when barrier can remind the blind person to hide by automatic speech alarming in the scope that ultrasonic wave passes to.
Since adopted that technique scheme, the utility model provide because it is simple in structure, not only be convenient to produce, and cost is very cheap is suitable for extensive popularization.
