Embodiment Construction

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] Please refer to figure 1 , the embodiment of the present invention provides a smart crutch based on NB-IoT network and ultrasonic obstacle detection, including a stick handle 1 and a stick body 2, the stick handle 1 is bent and connected above the stick body 2, and the stick handle 1 and rod body 2 are integrally formed.

[0020] An inductive switch 11 is installed on the stick handle 1, and the inductive switch 11 realizes automatic opening by sensing that someone touches the stick handle 1, and automatically closes when no one touches the stick handle 1.

[0021] A power supply 21 , an ultrasonic obstacle detection module 22 , a GPS positioning module 23 , an NB-IoT network module 24 , an MCU module 25 and an alarm 26 are installed on the stick...

Abstract

The invention discloses an intelligent walking stick based on a NB-IoT (narrow band internet of things) and ultrasonic barrier detection. The intelligent walking stick comprises a walking stick handleand a walking stick body, a sensing switch is mounted on the walking stick handle, a power supply, an ultrasonic barrier detection module, a GPS (global position system) positioning module, a NB-IoTmodule, an MCU (micro-programmed control unit) module and an alarm, the power supply is connected with the sensing switch, the ultrasonic barrier detection module, the GPS positioning module, the NB-IoT module, the MCU module and the alarm, the sensing switch is connected with the ultrasonic barrier detection module, the GPS positioning module, the NB-IoT module, the MCU module and the alarm, theultrasonic barrier detection module is connected with the MCU module, and the MCU module is connected with the GPS positioning module, the NB-IoT module and the alarm. The intelligent walking stick can timely find barriers to remind a user to elude the barriers, and a guardian can know position information of a blind person in real time.

Description

technical field [0001] The invention relates to a crutch for the blind, in particular to an intelligent crutch based on NB-IoT network and ultrasonic obstacle detection. Background technique [0002] Blind people usually need the help of crutches when traveling. Most of the crutches currently on the market have single functions, and they can only be held in the hand to judge whether there is an obstacle by knocking ahead. The rapid development of information technology in the 21st century has greatly changed all aspects of people's lives, especially the development of artificial intelligence and Internet of Things technology, which connects everything into a whole. Artificial intelligence technology has pushed the development of human science and technology to a new level. Applying these technologies to crutches can greatly facilitate the life of the blind, let the machine become their eyes, and let them feel what the eyes cannot see through sensor technology, thereby improv...
