Wireless area blind guiding system

Abstract

The invention relates to the field of blind guidance, discloses a wireless area blind guiding system which overcomes defects of traditional blind sidewalks and is composed of passive RFIDs and an intelligent blind guiding terminal, and provides a wireless intelligent area disabled assisting and blind guiding system capable of meeting demands of the blind. The wireless area blind guiding system is characterized in that the passive RFIDs are pre-buried on a road to form a radio frequency electric blind sidewalk which can be not seen from the surface of the road. Collected radio frequency blind sidewalk information can be processed through the intelligent blind guiding terminal carried by the blind; the position where the blind is located can be judged according to logic relations. The wireless area blind guiding system can remind the blind of the position and the surroundings where the blind is located through a synthesized voice broadcast form according to data information, guide the advancing direction and guarantee personal safety of the blind in the walking process. Meanwhile, the wireless area blind guiding system has the advantages of being low in device cost and convenient to use.

Description

technical field [0001] The invention relates to the field of blind guidance, in particular to a wireless intelligent area assisting disabled blind guidance system. Background technique [0002] At this stage, blind guide facilities for pedestrian crossings are mainly composed of strip-shaped straight and point-shaped blind pavement bricks paved on the road surface, but there are many problems in blind roads: irregular construction; damage; obstacles such as telephone poles, road signs, and newsstands in the middle; , goods, etc. are seriously occupied; the blind road is not connected. Just because there are so many problems, the blind dare not use the blind road, still use the blind stick to explore the sidewalk and walk the non-motor vehicle driveway according to the traditional way, so bring them very big personal safety problem. [0003] Some new blind-guiding devices, such as satellite positioning devices and infrared blind-guiding devices, are still in the experimental...
