Blind navigation system

Abstract

The invention discloses a blind navigation system, and relates to the technical field of navigation for the blind going out. A pair of blind navigation glasses and a blind special cell phone are connected through a glasses near-field wireless communication module and a cell phone near-field wireless communication module and are combined with a remote data processing center so that an intelligent blind navigation function can be achieved; an obstacle is detected through distance detection devices such as an ultrasonic distance detection device and an infrared distance detection device; when the blind encounters the obstacle in front, the distance and direction of the obstacle are measured through a distance detection sensor and then transmitted to a distance detection module of the blind special cell phone through the glasses near-field wireless communication module, and the blind is informed of the obstacle in front through a vibration prompting module and a voice prompting module after processing. Functions of obstacle early warning, traffic light recognizing, route planning, real-time positioning, distress information sending and additional information inquiring can be achieved.

Problems solved by technology

There are many disadvantages of this type of crutches. Its disadvantages are that it is difficult to find objects that are far away and objects that are suspended in midair.

The current domestically produced blind guide equipment also has various problems. For example, the walking stick with a horn has the advantage of making a sound to let others know the passage of the blind; the disadvantage is that even if the horn is damaged, the blind will not know.

Although the technology of foreign related equipment is mature, the price is too high and it is not suitable for promotion.
