Description

technical field [0001] The invention relates to the technical field of road rollers, in particular to an intelligent road roller system capable of autonomous operation. Background technique [0002] As one of the typical models of road machinery, vibratory rollers are widely used in the construction of infrastructure such as roads, water conservancy, railways, aviation airports, ports and large sites; with the development and progress of society, people gradually improve the quality of engineering construction , put forward higher requirements for the operation quality of the compaction equipment. Although the manufacturing level of the road roller body in China has been greatly improved, the human factors in the construction process of the road roller are inevitable, which has caused the compaction quality. The problem is more prominent. The vibratory roller operators often cannot strictly follow the compaction process. The main manifestations are: in order to reduce the vi...
