Intelligent Vibratory Roller Control System Research And Design

As the vibratory compaction theory slowly has been perfected, and the new compaction technology and the advanced control technology have been applied to the roller, the research of intelligent vibratory roller becomes the focus of the Compaction Machinery. This paper just aims at the control system of intelligent vibratory roller. First, the paper analyses the various vibratory parameters affecting the compaction, which acts as the basis of the control project of the control system. Then, contraposing the function demands, the paper divides the whole control system into several parts, such as the automatic and manual control of the compaction parameters,traveling controk veer and crab traveling control and intelligent watering and so on. At the same tune, the paper analyses and discusses the control projects of the above parts. As for the hardware of the control system, on principle of reliability and considering the badly working condition of the vibratory roller, the paper chooses the special controller specializing in the realm of Construction Machinery's control system in order to insure the reliability of the control system and simplify it. About the control quality of the system, the paper establishes the mathematical modes of the frequency modulation system and the amplitude modulation system, analyses the irrationality of the amplitude modulation project, puts forward to apply Proportional-Integral-Differential Controller (PID Controller) to the traveling system and frequency modulation system. This paper has still designed the software flow charts of all parts above referring to. Because of the innovation and the time limit, in the paper, the research of the control system of the intelligent vibratory roller is still not profound and detail enough and still expect to be improved.
