CANE for orientation in space people who have recently lost their sight

摘要

The proposed utility model relates to medical devices, and is used to inform the visually impaired and blind people about the presence of obstacles in the ergonomic area for their way, both on the street and indoors. Cane orientation in space people recently lost sight is formed as a tactile and canes has two ultrasonic rangefinder and one infrared motion detector, is fixedly mounted on the tactile canes. The relative position of the ultrasonic range finders and infrared motion sensor, their position relative to the longitudinal axis of the device allows to scan the space lying in front of the ultrasonic and infrared method. The first ultrasonic rangefinder is situated in the lower half of the tactile canes from its free end, the second ultrasonic rangefinder is situated in the middle of tactile canes from its free end. They are installed so that their acoustic axes are horizontal when the disability movement. Infrared movement sensor is disposed in the upper part of the cane haptic from its free end. It is mounted so that its optical axis is horizontal when moving disabled. The projection solid angles echo zones and infrared location forms a vertical plane perpendicular to the direction of movement of the user, holding in his hand the device for orientation in space of people who have recently lost their sight, the total working area, the shape and dimension to detect the presence of being in front of the instrument height of objects and the width of the growth of human figure. The design of the proposed utility model enables the result of alternate survey priemoizluchateley ultrasonic and infrared motion sensor to obtain data on the presence of obstacles, creating the risk of collision and distinguish people from other obstacles in ergonomic disabled space, develop new skills orientation in space of people who have recently lost their sight. The information is displayed on the obstacles for a person with vision disabilities as a voice message:; 1) Once the microprocessor via ultrasonic range finders, detects the obstacle at a distance of 0.8 meters (invalid ergonomic space area free), it will give the audio message "Obstacle" through dynamic head module output information;; 2) Once the microprocessor via ultrasonic rangefinder detect an obstacle at a distance of 0.8 meters (zone ergonomic space visually handicapped) and an infrared movement sensor registers a person at a distance of 0.8 meters (zone ergonomic space visually handicapped), the microcontroller will give an audio message "Obstacle-man" through the dynamic head of the module output.; Power electronic components canes for orientation in space of people recently lost their sight by a built autonomous power supply module.; 1 bp f ly-2-yl.
