In ancient China, there were also post roads. It also refers to the path to a goal, the path for things to develop and change. Road cracks are cracks that appear on roads, and they are divided into horizontal and vertical cracks.
[0003] There are still certain disadvantages in the use of crack monitoring equipment in the existing technology. Traditional crack monitoring equipment requires workers to hold a measuring head and bend over the ground to measure cracks on the road. This operation method increases the worker's measurement time, is not ergonomic, and the waist is easily injured.
