Micro blind guiding device based on single-chip microcomputer

Abstract

The invention provides a micro blind guiding device based on a single-chip microcomputer. The device comprises a penholder and a fastening earphone. One end of the penholder is connected with the fastening earphone. The internal of the device is provided with an ultrasonic generator, a distance sensor, an ultrasonic rangefinder, a 51 single-chip microcomputer, an infrared sensor, and a storage battery. The surface of the fastening earphone is provided with a display screen and a switching knob. An ultrasonic ranging module, a liquid crystal display module, and a voice broadcast module are electrically connected with the 51 single-chip microcomputer. Distance information is transmitted to the 51 single-chip microcomputer through the ultrasonic ranging module. The voice broadcast module can broadcast the distance information to a user in real time through the fastening earphone, so as to ensure privacy. The device is small in volume, convenient in carrying and hiding, so a blind person can walk freely. The blind guiding assembly does not need to use a guide dog. Through threaded connection of the fastening earphone and the penholder, the blind guiding assembly is miniature, and can accurately provide barrier information in real time, and the device would not draw attention of people.

Description

technical field [0001] The invention relates to a blind guide assembly, in particular to a miniature blind guide device based on a single-chip microcomputer. Background technique [0002] With the continuous development of science and technology, many problems in people's life or study have been solved. Among them, the group of blind people has also benefited from the development of science and technology, because of the emergence of guide rods, guide devices and guide dogs, It is possible for the blind to walk alone without human care, which facilitates the travel of the blind and ensures the safety of the blind. However, the existing blind guide components are expensive, and most people cannot afford them, so it is difficult to popularize them. The form of some products is too special, so that the blind are particularly obvious in the crowd, and it is difficult to hide from the public; the product function is too single, and cannot meet the various needs of the blind; Bli...

[0002] With the continuous development of science and technology, many problems in people's life or study have been solved. Among them, the group of blind people has also benefited from the development of science and technology, because of the emergence of guide rods, guide devices and guide dogs, It is possible for the blind to walk alone without human care, which facilitates the travel of the blind and ensures the safety of the blind. However, the existing blind guide components are expensive, and most people cannot afford them, so it is difficult to popularize them. The form of some products is too special, so that the blind are particularly obvious in the crowd, and it is difficult to hide from the public; the product function is too single, and cannot meet the various needs of the blind; Blind people have a psychological burden. At present, most products still need to be used in combination with guide dogs. However, some people in the blind group cannot use guide dogs due to their own reasons. These are the problems we want to solve
