Abstract

The invention discloses an autonomous operation intelligent road roller system comprising a road roller body, a machine control layer for controlling the motion of the road roller body, a perceive decision layer and a management planning layer; a carrier phase differential technology GNSS is adopted to realize high-precision positioning and course measurement; the vehicle body is provided with a millimeter wave radar for detecting obstacles in the periphery of the vehicle body; the vehicle body is provided with a laser radar and a camera used for high-precision map construction and side slopedetection of a rolling area, so that a management planning end can carry out rolling operation planning; an onboard compaction degree online detection technology is adopted to realize full-coverage online detection of the compaction degree, and a basis is provided for frequency modulation amplitude modulation; an expert system and a big data system are internally arranged in the management planning end, rolling planning can be autonomously performed according to the characteristics of the construction site compacted material, the parameters of the road roller, the compaction degree informationand the high-precision map, and cluster compaction data sharing and collaborative operation is realized; the vibration energy output can be adjusted in real time by the road roller according to the compaction progress, and the compaction quality and efficiency are effectively improved.

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...
