Pneumatic lifting blind person zebra crossing

Abstract

The invention relates to a pneumatic lifting blind person zebra crossing. The pneumatic lifting blind person zebra crossing comprises a shell body, a moving component and a pneumatic transmission component; the shell body comprises a groove, the moving component is at least partially arranged in the groove, and the moving component is capable of rising and falling in the groove; the pneumatic transmission component comprises an air bag and a main control device; the air bag is arranged in the groove and located under the moving component; and the main control device controls the air exhaust and air supply of the air bag to drive the moving component to move vertically in the groove of the shell body. The pneumatic lifting blind person zebra crossing has the advantages that a main control module in the pneumatic transmission component communicates with traffic lights to acquire information, so that the rising and falling of the zebra crossing are achieved, the rising and falling time isshortened, the normal passing of a vehicle is not impeded, and the noise cannot be made; even though the violative passing or line pressing and other similar situations occur when the green light blind person zebra crossing is raised, the air in the air bag can be naturally compressed, and the moving component is lowered, thereby effectively avoiding the situation that heavy vehicles damage the blind person zebra crossing due to pressing, and the pneumatic lifting blind person zebra crossing has an excellent self-protective ability.

Description

technical field [0001] The invention relates to a traffic zebra crossing, in particular to a pneumatic blind zebra crossing. Background technique [0002] There are millions of blind people in China, the largest blind group in the world, including tens of millions of visually disabled patients. Although China already has the longest and most widely distributed blind roads in the world, all of these blind roads are ruthlessly cut off before the zebra crossing, where people must pass when crossing the road. As a sign of pedestrians crossing the street, the zebra crossing is also a necessary place for the blind and sighted in some special places. But existing zebra crossing does not have any effect of prompting to the blind. [0003] In response to the above problems, research institutions and technology companies at home and abroad tend to focus on smart wearable devices. However, these devices have disadvantages such as high cost, poor precision, and only suitable for labor...

AI Technical Summary

Problems solved by technology

There is a precedent in China. On April 25, 2010, the first blind zebra crossing in China was laid on a special road in front of the Suzhou School for the Blind and Deaf. Although it received rave reviews at the beginning, this blind zebra crossing will not only affect the normal driving of cars, Also easy to make noise

In the end, it only existed for about half a month before being demolished, and the problem has not been resolved until now
