Embodiment 1

[0041] according to Figure 1 to Figure 6 As shown, an auxiliary device for blind people crossing the street, including: a traffic signal transmitter 1 arranged on a zebra crossing aisle, a positioning device 2, and a guiding stick 3 held in the hand of a blind person;

[0042] The guiding stick 3 includes a stick body 31 and a signal transceiving mechanism 32, an audio player 33 and a controller 34 arranged on the stick body 31;

[0043]The positioning device 2 includes three ultrasonic receivers 22, and the ultrasonic receivers 22 are arranged at three corner positions in the zebra crossing aisle, and the coordinates are respectively (0, 0), (a, 0), (0, b) where a, b are the length and width of the road, and the ultrasonic receiver 22 is provided with a signal feedback device 23;

[0044] Signal transceiving mechanism 32 comprises, the ultrasonic transmitter 323 that matches with ultrasonic receiver 22 and the signal receiver 324 that receives signal feedback device 23 sign...

Embodiment 2

[0057] The difference from the above-mentioned embodiment 1 is that, according to Figure 4 , Figure 5 As shown, the upper end of the rod body 31 is provided with a telescopic rod 35; the positioning device 2 also includes an infrared positioning column 21 arranged at a diagonal position of the zebra crossing; the signal transceiver mechanism 32 also includes a traffic signal receiver 321 and an infrared transmitter 322; The infrared emitter 322 is arranged on the top of the telescopic rod 35, and the infrared emitter 322 includes 4 infrared emitting heads 3221 uniformly distributed by the circumference; 322 is connected, and the signal sent by the infrared emitting head 3221 will be fed back to the controller 34 after being blocked by the infrared positioning column 21.

[0058] After the telescopic rod 35 is stretched to the highest position, the vertical distance between the infrared emitter 322 and the ground is 1.8-2.2m, and the vertical height of the infrared positioni...

Embodiment 3

[0061] The difference from the above-mentioned embodiment 1 or 2 is that according to figure 2 As shown, the two sides of the guide stick 3 are provided with light-emitting strips 6, the light-emitting strips are LED light strips, which have a flickering function after being powered on, and are used to warn passing cars and pedestrians. The surface of the guiding stick 3 is provided with a solar panel 7, and solar energy is used to supply power to the devices on the luminous bar 6 and the guiding stick 3, so as to save energy and improve the battery life of the guiding stick 3.

Abstract

The invention relates to the road traffic indication field and particularly relates to an auxiliary equipment for assisting the blind to cross the road. The auxiliary equipment comprises a traffic signal emitter arranged on a zebra crossing, a positioning device and a guide rod held by a hand of the blind, wherein the guide rod comprises a rod body, and a signal transceiver mechanism, an audio player and a controller which are arranged on the rod body, the positioning device comprises at least three supersonic wave receivers, the supersonic wave receivers are arranged at three non-linear positions on the zebra crossing and are internally provided with signal feedback devices, the signal transceiver mechanism comprises a supersonic wave emitter in matching with the supersonic wave receivers and a signal receiver used for receiving signals of the signal feedback devices, and the supersonic wave emitter and the signal receiver are connected with the controller through signal wires.

Description

technical field [0001] The invention relates to the field of road traffic indication, in particular to an auxiliary device and method for blind people crossing the street. Background technique [0002] Blind people are a group of social groups that cannot be ignored, enjoying the same rights as normal people. Blind people walking on the road, because they cannot see the road conditions, are always in danger, especially when crossing the road on the sidewalk, when there is no one to support and guide the blind people , It is easy to go astray and deviate to the area other than the sidewalk, causing danger. The authorized announcement number is CN202711465U, which discloses a road crossing audio indicating device, which includes a signal transmitting unit, a signal receiving unit, a control unit and an audio generator, and the signal transmitting unit is installed on the side of the road and connected to the road indicator light , transmitting different indication signals acc...
