Embodiment Construction

[0020] The casing ⑥ and the slider ⑤ are made of plastic, and the joints of the two are connected by slide rails to realize sliding, extension and retraction. Ultrasonic ranging sensors ② can be purchased, such as model: URM37 V3.2, SRF05, SRF08, SRF02, or can be manufactured by yourself. The circuit board ③ adopts batch printed circuit board, and the main control chip on it adopts ATMEL @ The company's Atmega8, the relevant circuit is attached figure 2 shown. Servo ④, ESKY is used here @ The company's 9g (gram) steering gear. In fact, it can be made smaller, so that the overall volume can also be smaller. Battery ① Use 2 AAA batteries. When in use, hold the blind guide instrument with the part of the ultrasonic distance measuring sensor ② forward, and the palm leans against the slider ⑤. When the finger points to a certain position, the slider ⑤ will move.

Abstract

The invention relates to a hand-held touch blind-guiding instrument which utilizes an ultrasonic distance-measuring technology and an embedded type system technology, informs the blind person whether an object exists in the interested direction as well as the distance of the object by the touch of the movement of a sliding block. The hand-held touch blind-guiding instrument control an ultrasonic distance-measuring sensor by a single chip microcomputer to measure the distance information of the object in the direction pointed by the sensor, controls a steering engine to move by calculation, drives the sliding block to shrink according to proportion, presses the palm of the blind person, informs the blind person of the distance of the pointed object from self by the distance of the extended part. The blind person can know the distribution condition of surrounding objects in a linearization manner by using the equipment, can obtain an outline drawing of approximate distance of the surrounding environment and can obtain the exact distance of the object in a certain direction from self by calculation.

Description

technical field [0001] The invention relates to ultrasonic ranging, tactile sensing, and blind-guiding instruments and equipment. The main function is to provide proportional linearized distance information of the surrounding environment for blind people. Background technique [0002] Blind people are extremely helpless in perceiving the world, and it is not enough to just hit the ground with a blind stick. As people pay more and more attention to this vulnerable group, various guide devices for the blind have been designed one after another. A lot of related research is going on. But so far there is no intuitive and easy-to-use device that is more friendly to the health of the blind and has low cost. [0003] The current works of others related to this field include: ultrasonic guide glasses that warn when a set dangerous distance is detected; improved earphones that tell the distance through the sound frequency; tell the distance through the strength of the vibration U...
