Abstract

The invention discloses a vibration control method, system and device for a road roller. The method comprises the following steps: monitoring whether a switch command for switching a vibration manner is received in a vibration process of the road roller in a preselected vibration manner; and when the switch command is monitored, controlling the road roller to automatically stop the vibration and vibrate in a new vibration manner at a preset delay time point, wherein preset time is longer than or equal to time required for the vibration stopping of the road roller. According to the vibration control method, the technical problem that the service life of the vibration system of the road roller is shortened because a hydraulic system is greatly impacted during the direct switching of multiple vibration manners of the road roller is solved.

Description

technical field [0001] The invention relates to the field of road roller control, in particular to a vibration control method, system and device for a road roller. Background technique [0002] At present, most commonly used road rollers are double-drum vibratory rollers. Double-drum rollers are a kind of asphalt pavement construction equipment, which are mainly used for rolling asphalt pavement just laid by asphalt paver. The asphalt pavement is vibrated and compacted by double-drum rollers with non-stop tonnage. [0003] The current vibration control system of twin-drum rollers generally adopts manual control method, and its functions are often relatively single. Due to the diversity of modern pavement construction techniques, it is necessary for the double drum vibratory roller to be able to realize the combined use of various vibration functions or to switch between various vibration modes during operation, but most of the current market only A simple direct switching ...
