Outdoor blind guiding robot based on global position system (GPS), general packet radio service (GPRS) and radio frequency identification devices (RFID) and navigational positioning method

Abstract

The invention discloses an outdoor blind guiding robot based on a global position system (GPS), general packet radio service (GPRS) and a radio frequency identification devices (RFID) and a navigational positioning method. The outdoor blind guiding robot comprises an outdoor blind guiding robot body and a remote service platform, wherein the outdoor blind guiding robot body comprises a vehicle body and a navigation handle, and the vehicle body is sequentially divided into four layers from bottom to top. The navigational positioning method includes that the GPS and an RFID module are adopted to position blind persons and broadcast position navigation information through voices; a GPRS module is adopted to achieve two-way transmission of data between the blind guiding robot and family members or the remote service platform, and the blind persons are monitored and are remotely guided to advance; when the blind persons have accidents, voice help calling can be performed by the GPRS module to the remote service platform; and the image recognition technology is adopted to recognize manual navigation road signs and friendly tracks on the roads so as to ensure accuracy and safety of routes. The outdoor blind guiding robot and the navigational positioning method solve the outdoor traveling problem of the blind persons.

Description

technical field [0001] The invention relates to a blind-guiding device, in particular to an outdoor blind-guiding robot based on GPS, GPRS and RFID and a navigation and positioning method that is cost-effective, strong in practicability, wide in application range, safe and reliable, and suitable for blind people. Background technique [0002] Visual impairment is a disease that seriously affects the quality of human life. There are about 140 million visually impaired people in the world, and on average, a blind person is born in the world every 5 seconds. There are nearly 15 million visually impaired patients in my country, and the number of new blind people is increasing by 450,000 every year. The visually impaired can only use 60% of the senses to gain experience. They cannot perceive the surrounding environment information like us normal people, so they can move freely. Another option for a large group of people to live a normal life, and using guide robots to assist th...
