Blind person navigation bluetooth beacon

Abstract

The invention discloses a blind person navigation bluetooth beacon. The blind person navigation bluetooth beacon includes a single-chip microcomputer, a bluetooth communication module, a power supply portion, and a memory for storing navigation prompt information; the single-chip microcomputer is connected to the bluetooth communication module and the memory through an I / O interface; the bluetooth communication module invokes the navigation prompt information in the memory through the single-chip microcomputer; and the power supply portion performs rectification and voltage stabilization on commercial power and then outputs direct current to the single-chip microcomputer. In actual use, the blind person navigation bluetooth beacon is arranged on key node parts of public places (such as corners, stairs, and elevators), a blind person opens a mobile phone bluetooth receiving function before going out, starts a mobile phone APP navigation program, wears an earphone connected to a mobile phone, and can receives signals sent by a bluetooth beacon once entering a coverage of the bluetooth beacon in public places; And the current location of the blinder person, the next walking direction, surrounding main functions and service mechanisms and facilities are provided to the blinder person through voice prompt, and travelling of the blind person is facilitated.

Description

technical field [0001] The invention relates to a navigation system, in particular to a bluetooth beacon for blind navigation. Background technique [0002] At present, there are quite a lot of Bluetooth communication modules and Bluetooth products. Such as Bluetooth headset, Bluetooth remote control toys, Bluetooth mouse and so on. There are two communication application modes of Bluetooth: point-to-point communication mode and point-to-multiple communication mode. Bluetooth version 2.0 and above can realize network communication between one master device and seven slave devices. The disadvantage of Bluetooth is that it consumes a lot of power. With the advent of Bluetooth 4.0, it saves 90% of power compared to Bluetooth 3.0, which lays the foundation for Bluetooth to enter a wide range of applications. [0003] It is always difficult for blind people to navigate in public places (such as subway stations, large shopping malls, parks, etc.), and blind passages alone cannot...

Problems solved by technology

The disadvantage of Bluetooth is that it consumes a lot of power. With the advent of Bluetooth 4.0, it saves 90% of the power compared to Bluetooth 3.0, which lays the foundation for the widespread application of Bluetooth.

[0003] It is always very difficult for the blind to navigate into public places (such as subway stations, large shopping malls, parks, etc.), and the blind passage alone cannot solve the problem fundamentally. Guide dogs are banned from entering many public places, which greatly affects the activities of the blind.
