Blind-person accurate navigation method based on internet

Abstract

The invention discloses a blind-person accurate navigation method based on the internet. Most traditional blind-person navigation devices are common canes, and blind persons judge the walking direction by beating the ground and peripheral objects. In a handheld blind-person navigation device, a PXA270 serves as a main control module, RFID serves as the core technology, and the Internet of Things serves as a platform; a radio frequency identification (RFID) path is set on a blind channel, an embedded system is solidified in a storage, a circuit system in the device queries a related database according to input information, a most-reasonable RFID navigation path with the blind channel buried with the radio frequency identification (RFID) is generated, and RFID navigation is started; in the blind-person walking process, different reminders are continuously provided for the RFID read through matching. The blind-person accurate navigation method based on the internet belongs to the field ofblind-person navigation, and is particularly applied to the blind-person handheld navigation device based on the RFID.

Description

Technical field: [0001] The invention relates to the field of navigation, in particular to an Internet-based precise navigation method for blind people. Background technique: [0002] Traditional navigation devices for blind people are mostly ordinary walking sticks. Blind people judge the direction of walking and whether to stop by knocking on the ground and surrounding objects. This kind of walking stick has many disadvantages. Its main disadvantage is that it cannot find distant obstacles and Suspended objects in front of blind people, and the current domestic blind guide system also has similar problems, such as: navigation stick with speaker, the advantage is that it can emit light at night to remind passers-by and drivers, but the disadvantage is that it is fragile and too sensitive. The blind glasses for the obstacles in front have the advantage of small size, but the disadvantage is that the measurement range is small. The travel problem of the blind has been plagued...

[0002] Traditional navigation devices for blind people are mostly ordinary walking sticks. Blind people judge the direction of walking and whether to stop by knocking on the ground and surrounding objects. This kind of walking stick has many disadvantages. Its main disadvantage is that it cannot find distant obstacles and Suspended objects in front of blind people, and the current domestic blind guide system also has similar problems, such as: navigation stick with speaker, the advantage is that it can emit light at night to remind passers-by and drivers, but the disadvantage is that it is fragile and too sensitive. The blind glasses for the obstacles in front have the advantage of small size, but the disadvantage is that the measurement range is small. The travel problem of the blind has been plagued by the blind all their lives. How to safely and accurately help the blind to reach the destination safely and accurately is to provide precise and safe information for the blind. Navigation, solving the primary problem of blind travel
