after the sensor detects a signal of an intelligent bracelet of the blind, the signal is used for synchronously feeding back display information of a traffic light at the position of the blind to the blind through a traffic signal machine, the blind selects whether to pass through the intersection after receiving feedback information of the traffic light in a vibration mode of the intelligent bracelet, and when the blind passes through the intersection, the sensor forwards prompt information of the intelligent bracelet of the blind, which passes through a road section, to a driver of a motor vehicle within a 50m circumference range near the traffic light through a cloud sharing technology, so that the driver is reminded to give the blind; the GPS chip calculates that the blind person passes through the intersection when passing through the intersection according to map software, the circuit board controls the dial to emit red light to remind the passing motor vehicle to present the blind person, the dial is lightened and simultaneously linked to start the electromagnet, the electromagnet rotates in the ball track in the clockwise direction, the electromagnet drives the ball to rotate in the clockwise direction, the ball protrudes outwards when rotating, the blind person obviously feels that the ball rotates, the GPS chip uploads the information to the circuit board after detecting that the blind person passes through the intersection, the circuit board controls the dial to automatically extinguish the red light, the electromagnet stops rotating, the ball stops rotating immediately and automatically sinks into the ball track to remind the blind person to pass through the intersection smoothly.
2. The intelligent transportation device for assisting the blind in going out of the way as claimed in claim 1, wherein when the blind walks to the intersection within the circumference of 5m radius around the traffic light, the intelligent bracelet reminds the blind of the traffic light by means of 2 times of short vibration of the vibration module, and as the distance between the blind and the traffic light gets closer and closer, the interval of 2 times of vibration of the intelligent bracelet gets shorter and shorter, so as to guide the blind to reach the traffic light, and after the blind senses the traffic light, the blind knocks the intelligent bracelet 2 times to stop the vibration reminding, and at the same time, the intelligent bracelet sends a signal to a sensor built in the traffic light, and the sensor immediately feeds back the red light display information of the traffic light to the intelligent bracelet through the traffic signal machine, and when the traffic light is red, the intelligent bracelet reminds the blind of the traffic light to be in a red light state through 3 times of short vibration of the vibration module, the blind person waits at the intersection, when the traffic light is a green light, the intelligent bracelet reminds the blind person of the green light state of the traffic light in a vibration mode with long interval time of 2 times of the vibration module, the blind person passes through the intersection, when the blind person passes through the intersection, the sensor sends data information of the blind person passing through the intersection to a motor vehicle which takes the sensor as a circle center and has a radius of 50m through a fifth generation mobile communication technology, a driver of the motor vehicle is reminded of avoiding in advance, meanwhile, when the GPS chip detects that the blind person passes through the intersection, the intelligent bracelet sends out red light to remind the driver, the ball reminds the blind person passing through the intersection in a rolling mode, the GPS chip reminds the blind person of passing through the intersection, the red light is extinguished, and the ball reminds the blind person of passing through the intersection in a rolling.
3. The intelligent transportation device for assisting the blind in traveling according to claim 1, wherein the corresponding relationship between the vibration mode of the intelligent bracelet and the information shown by vibration is as follows: the 2-time vibration with short interval time represents that the blind person starts to vibrate when the distance between the blind person and the traffic light is 5m, and the 2-time vibration interval time of the intelligent bracelet is shorter and shorter as the distance between the blind person and the traffic light is closer and closer; the 3-time short-interval vibration represents that the traffic light of the intersection where the blind person is located is in a red light state; the 2-time long-interval vibration represents that the traffic light at the intersection where the blind person is located is in a green light state.
