Device and method for assisting blind people to cross the road

Abstract

The invention relates to the road traffic indication field and particularly relates to a device for assisting the blind to cross the road and a method. The device 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 positioning device comprises an infrared positioning column arranged at a diagonal position of the zebra crossing, 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, and a telescopic rod arranged at an upper end of the rod body, the signal transceiver mechanism comprises a traffic signal receiver and an infrared emitter, the infrared emitter is arranged at a top portion of the telescopic rod, the infrared emitter comprises four infrared emitter heads which are circumferentially and uniformly distributed, the controller is connected with the traffic signal receiver, the audio player and the infrared emitter through signal wires, and signals emitted by the infrared emitter heads are blocked by the infrared positioning column and are then fed back to the controller.

Description

technical field

[0001] The invention relates to the field of road traffic indication, in particular to a device and method for assisting blind people to cross the road. 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 accord...

Embodiment 1

[0043] according to Figure 1 to Figure 5 As shown, a device for assisting the blind to cross the road includes: a traffic signal transmitter 1 arranged on the zebra crossing aisle, a positioning device 2 and a guiding stick 3 held in the hand of the blind;

[0044]The positioning device 2 includes an infrared positioning column 21 arranged at a diagonal position of the zebra crossing;

[0045] Guide stick 3 comprises, stick body 31 and the signal transceiving mechanism 32 that is arranged on stick body 31, audio player 33, controller 34 and the telescoping rod 35 that is arranged on stick body 31 upper ends, and signal transceiver mechanism 32 comprises, traffic signal receiving Device 321 and infrared emitter 322;

[0046] according to image 3 As shown, the upper end of the stick body 31 is provided with a handle 5 , and the handle 5 is provided with dimples 51 .

[0047] The infrared emitter 322 is arranged on the top of the telescopic rod 35, and the infrared emitter 3...

Embodiment 2

[0055] The difference from the above-mentioned embodiment 1 is that, according to Figure 5 , Figure 8 As shown, the positioning device 2 of a device for assisting the blind to cross the road in this embodiment 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; the signal transceiving mechanism 32 also includes, and the ultrasonic receiver 22 The matching ultrasonic transmitter 323 and the signal receiver 324 receiving the signal from the signal feedback device 23 are connected to the controller 34 through a signal line.

[0056] according to Figure 4 As shown, the guide pole 3 is provided with a guide 4 at the lower end, and the guide 4 includes a diverter 41 and a guide wheel 42 , and the diverter 41...

Embodiment 3

[0065] The difference from the above-mentioned embodiment 1 or embodiment 2 is that in step ②, the infrared transmitter monitoring and guiding method and the ultrasonic transmitter monitoring and guiding method are used at the same time, so as to further improve the safety of blind people crossing the road.
