Abstract

A novel multifunctional ultrasonic wave blind-guiding device can detect accumulated water of the road based on realization of ultrasonic wave blind-guiding. A sound prompting module is used for providing obstruction and accumulated water information in front of the road for the user for guiding advancing of the user. A vibration prompting module is used for assisting to prompt the obstruction and accumulated water information in front of the road. When the obstruction is nearer, the vibration frequency is higher; and when the obstruction is farther, the vibration frequency is lower. If accumulated water exists, vibration is repeated continuously until a place without water, thereby facilitating walking of the blind person. Accidental falling-down of the user is detected through an acceleration module. The current location information which is measured by a GPS module is transmitted to the family member through a GSM module and short messages. The family members can also inquire the current location of the user through a short message mode. An optical prompting module performs an alarm effect through light reflection function and improves safety factor of daily walking.
