Problems solved by technology
[0002] At present, there are many kinds of blind guide devices, such as guide shoes, guide glasses, guide sticks, etc., but most ultrasonic emitting devices are installed on shoe uppers, glasses or crutches. It is prone to shaking, which will interfere with the launch and greatly affect the results obtained
Many blind guide devices based on the ultrasonic principle have only one ultrasonic emitting device, and the direction is relatively single, and the measured results are not very reliable.
There are only vibration and voice prompts for prompts, which is not convenient to use

The invention discloses an intelligent guide system based on an ultrasonic distance measuring principle. The left shoe tip and the right shoe tip of a person are fixedly sleeved with a left shoe cover module and a right shoe cover module respectively, and a waistband module is fixedly arranged around the periphery of the waist of the person. Ultrasonic sensors, pressure sensors, vibration modules and wireless communication modules in the left shoe cover module and the right shoe cover module are respectively connected with a shoe cover single-chip microcomputer. Four ultrasonic sensors, a voice module and a wireless communication module in the waistband module are respectively connected with a waist single-chip microcomputer. The intelligent guide system enables the waist of a blind person to slightly move, a certain direction can be detected from multiple positions of the body, and a result is more stable and more reliable. Detection is guaranteed to be carried out when the blind person stably walks, and the situation that errors occur to the measurement result of the front portions of the feet when the person lifts the feet to walk can be prevented. A wireless transmission mode solves the problems caused by wired circuit wearing, and the intelligent guide system is made to be more humanized and more convenient to use. The intelligent guide system is suitable for the shoes with various sizes, lowers cost and is strong in generalization performance.
Description
technical field [0001] The invention relates to an intelligent blind guiding system, in particular to an intelligent blind guiding system based on the principle of ultrasonic distance measurement. Background technique [0002] At present, there are many kinds of blind guide devices, such as guide shoes, guide glasses, guide sticks, etc., but most ultrasonic emitting devices are installed on shoe uppers, glasses or crutches. It is prone to shaking, which will interfere with the launch and greatly affect the results obtained. Many blind guide devices based on the principle of ultrasound have only one ultrasonic emitting device, and the direction is relatively single, and the measured results are not very reliable. There are only vibration and voice prompts for prompts, which are not convenient to use. Contents of the invention [0003] In order to overcome the shortcomings of existing products and fully consider the actual needs of the blind, the purpose of the present inv...
