[Abstract]:With the rapid development of transportation in China, the rapid development of construction machinery in China, the corresponding construction machinery is constantly innovating. Computer science and technology and electronic technology are constantly infiltrating into it, forming a new subject of electromechanical integration. In addition, with the continuous development and penetration of servo hydraulic technology, the electromechanical and hydraulic integration technology has been gradually improved and matured, which makes the construction vehicle enter the period of high-speed development. The application of new ideas and new technologies has greatly improved the working efficiency of the current advanced double-wheel vibratory roller, and the roller is becoming more intelligent, automatic, efficient and high-quality. Based on the double steel wheel vibratory roller, the linear walking and intelligent sprinkler system of the roller are further improved in this paper, so that the operational efficiency of the roller has been greatly improved. The main work of this paper is as follows:. Analyze the background and development of the roller, understand the related technology and future development direction; The methods and mechanism of road compaction of road compactor are analyzed, the factors influencing compaction quality of road roller are analyzed, and the working mechanism of road compaction and the influence of road compaction are studied in detail. PLC, the core controller of linear walking and intelligent sprinkling of roller, is analyzed, and its related functional characteristics are analyzed. The overall layout of the program and the modular programming are also carried out. It can effectively control the related functions of linear walking and intelligent sprinkler. A set of effective roller walking system is designed. By using the closed-loop control principle, the problem of the traditional roller in the compaction process is solved, and the hydraulic steering system of the roller is designed. Based on the analysis of crab line system, an innovative and more efficient direction control method of road roller is put forward in order to realize the function of steering and running directly and provide great convenience for the driver to drive the roller. Through the new innovative design of sprinkler system, making it more water-saving, more efficient, more stable, more convenient to operate, more intelligent, solved the difficult problem in sprinkler control of road roller. Improved the automation of road roller intelligent. A combination of design principles and methods to make the product more humanized.
