Auto-updated intelligent guiding device capable of man-machine conversation for blind people

Abstract

The invention relates to an auto-updated intelligent guiding device capable of man-machine conversation for blind people. A base plate is connected to a CPU, The base plate is connected to a motor, a motor connected to a rotating wheel, the base plate is connected to a shell, the shell is connected to a handle, and moreover, four radar sensors are mounted below the base plate, wherein a voice module is connected to the CPU, a voice device and a loudspeaker; the CPU is also connected to a signal reception and processing device; the signal reception and processing device is also connected to a spherical radar sensor arranged at the top center outside the outer shell, and the four radar sensors. The device has the advantages that by using a voice module to conduct voice conversion, the function of man-machine conversation is realized; by using a rhombus-node connection design and a spherical device, the function of freely adjusting the length of the handle and the rotation angle within the range of 360 degrees without a dead angle is realized; by the means of adopting the rotating wheel with a planet gear structure, the functions of automatically climbing over barriers and easily swerving are realized.

Description

Technical field [0001] The invention relates to the field of electronic blind guide equipment, in particular to an intelligent blind guide device that automatically updates man-machine dialogue. Background technique [0002] Blind people are a special group of people with disabilities. They lose visual information due to congenital or acquired physical defects. However, visual information is the main source of knowledge and experience for human beings. Therefore, blind people are greatly affected in daily life and safe travel. Restriction, in real life, most blind people use ordinary blind sticks to assist in walking. This kind of blind stick is just an ordinary long pole, which can only detect local obstacles and has too many shortcomings. Although guide dogs can assist and guide the blind, they have the disadvantages of long training period and adaptation period and high cost. This also makes the use rate of guide dogs not high. [0003] In order to assist the blind to move safe...

AI Technical Summary

Problems solved by technology

[0004] my country is the country with the largest number of blind people in the world. There are about 5 million blind people, accounting for 18% of the total number of blind people in the world. In terms of absolute figures, the total number of blind people in China has already exceeded the population of countries such as Denmark, Finland or Norway. There are 450,000 blind people. If the current trend is allowed to remain unchanged, the total number of blind people in my country is expected to increase by 4 times by 2020. The current guide aids for blind people in my country are generally ordinary blind sticks. With the rapid development of science and technology, This kind of backward blind guide aids can no longer meet the needs of modern life, and traffic accidents of blind people have occurred frequently. Whether it is the huge market demand for electronic guide aids or the contradiction between backward guide aids and modern life, All will promote the rapid development of electronic blind guide

[0005] Due to the loss of visual information, the blind cannot avoid obstacles in a timely and accurate manner. The GPS smart blind guide is an important auxiliary tool to assist the blind to travel safely. In the modern urban traffic system, there are traffic lights, blind roads, zebra crossings and other information. The basic guarantee for blind people to travel safely, but the current electronic blind guide cannot fully recognize and judge these traffic information
