Embodiment Construction
[0013] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments.
[0014] in figure 1 In, an ultrasonic ranging bracelet includes a strap 1 and an ultrasonic ranging system 2. The ultrasonic ranging system 2 has a built-in single-chip controller 3, and the ultrasonic ranging system 2 has an ultrasonic sensor 4 on the front. The wire 7 of the ultrasonic ranging system 2 is connected to the single-chip controller 3. The ultrasonic ranging system 2 has a speaker 5 on the side, and is connected to the single-chip controller 3 through the wire 7 built in the ultrasonic ranging system 2. The outer surface of the strap 1 is provided with a solar panel 6, which is connected to the ultrasonic distance measuring system 2 through a wire built in the strap 1.

The invention relates to an ultrasonic ranging wristband which comprises a binding strap and an ultrasonic ranging system. A single-chip microcomputer controller is arranged in the ultrasonic ranging system, an ultrasonic sensor is arranged on the front side of the ultrasonic ranging system and connected to the single-chip microcomputer controller through a wire arranged in the ultrasonic ranging system, a loudspeaker is arranged on one side face of the ultrasonic ranging system and connected to the single-chip microcomputer controller through a wire arranged in the ultrasonic ranging system, a solar cell panel is arranged on the outer surface of the binding strap and connected to the single-chip microcomputer controller through a wire arranged in the binding strap, and the detection distance of the ultrasonic sensor is set to be within 10 m. In order to solve the problems that a blind person cannot walk conveniently, and time is wasted when the blind person walks into a dead end street, the measurement result can be broadcast in real time through the loudspeaker, power is supplied to the ultrasonic ranging system through the solar cell panel, and therefore energy conservation and environment protection are achieved.
Description
Technical field [0001] The invention relates to the field of electronic products for the blind, in particular to an ultrasonic distance measuring bracelet. Background technique [0002] When walking, blind people only rely on the touch of crutches, and they often find out when they encounter obstacles. If they walk into a dead end, or there are many obstacles in front of the road ahead, it is not easy to walk, and it has been wasted by the time they find it. Too much time and not safe. Summary of the invention [0003] In order to solve the above-mentioned inconvenience of walking for the blind, the present invention provides an ultrasonic ranging wristband specially designed for the blind. [0004] The technical scheme of the present invention is as follows: an ultrasonic ranging bracelet, including a strap and an ultrasonic ranging system, the ultrasonic ranging system is built with a single-chip controller, and the ultrasonic ranging system has an ultrasonic sensor on the front,...
