[0002] During the road power construction process, it is necessary to add warning signs to remind passing pedestrians and vehicles. Traditional warning signs are made of angle steel and tinplate, and warning words are written on the tinplate with paint or fluorescent paint. This traditional method will become blurred due to long-term sun, wind and rain corrosion or wear, and the human eye can hardly see it at night, and it has no warning effect. It often causes non-construction vehicles or non-construction personnel to mistakenly enter the construction site, causing personal accidents and traffic accidents.

[0003] In order to improve the warning effect, some construction units use fixed display screens or warning lights or warning signs that combine the two. Warning text is input on the display screen to scroll, which improves the warning effect. However, the warning effect of static warning signs is still relatively low. In addition, there are drivers, cyclists, pedestrians, etc. with different visual ranges passing by the construction site. The warning effect of fixed-height warning signs is different for people with different visual ranges, and not all of them are strong. Therefore, there will be some safety hazards.
