Intelligent blind guide stick and blind guide method thereof

Abstract

The invention discloses an intelligent blind guide stick and a blind guide method thereof. The intelligent blind guide stick comprises a handle portion, a telescoping portion connected to one end of the handle portion, and a ground touching portion connected to one end of the telescoping portion. The handle portion is provided with a control module, an ultrasonic ranging module and a vibration module, the control module is electrically connected with the ultrasonic ranging module, and the vibration module is electrically connected with the control module. Whether a barrier exists around a walking path of a user can be detected at a long distance through ultrasonic ranging; when the barrier is detected, the condition can be timely fed back to the user in a vibration manner, and the user can be prompted to keep away from the barrier; and when emergency conditions happen, emergency call can be carried out through dial-up to effectively contact family members timely.

Description

technical field [0001] The invention belongs to the field of auxiliary tools for the blind, in particular to an intelligent blind-guiding stick and a blind-guiding method thereof. Background technique [0002] Due to its physical defects, blind people cannot be used to observe and walk with naked eyes. Therefore, blind people need to rely on others or use auxiliary tools to help walk in daily life. At present, the blind mostly use guide sticks to assist walking. [0003] However, the current blind guide stick has the following problems due to its structural defects: because the swing range of the blind guide stick is limited during walking, obstacles outside the swing range cannot be detected, and at the same time, it cannot effectively avoid fast approaching obstacle. Potentially dangerous to the user. Contents of the invention [0004] In order to overcome the shortcomings and deficiencies in the prior art, the present invention provides a blind-guiding method of an i...
