【摘要】：压路机是路桥建设施工中不可或缺的高效压实机械，目前国内振动压路机，尤其是智能振动压路机在压实质量方面与国外同类产品存在很大的差距，而压实质量的优劣与压路机检测系统和控制系统的性能有直接关系。为此，本文在分析当前国内外智能振动压路机原理的基础上，研究高性能、高水平的压路机实时检测系统和智能控制系统，为高端智能振动压路机的研究开发做了有益的探索和开拓性的工作。 文中首先对智能压实技术的相关概念和优点进行阐述，介绍了智能压实技术的应用；在振动压实机理基础上，构建“振动轮-土”动力学模型，并基于MATLAB/SIMULINK对动力学模型进行了仿真，进一步验证理论分析的正确性。分析了振动压路机本身的因素对压实效果的影响；根据这些因素，结合当前的研究现状，提出了振动压路机智能化的关键技术，即压实度实时检测系统和智能控制系统。 在压实度检测新方法的基础上，本文提出了随车式压实度实时检测技术；分析现有的压实度评价方法的优缺点，针对振动压实过程的线性特征和非线性特征，提出了基于多个振动特征参数的压实度评价方法；研究具有压实度实时检测功能的压路机的构成和工作特点，压实度实时检测系统和系统中振动加速度信号的提取与处理，为智能压路机实时检测系统和新型压实度仪的研究和开发提供了理论基础。 根据压路机智能控制系统的要求和实现的总体功能，针对压实参数的自动控制，进行了调频系统、调幅系统和行驶速度系统的智能控制设计。由于振动压实过程的复杂和不确定性，提出了模糊控制的智能压实控制方案，，采用CAN总线实现数据信息的传输，选用专用的EPEC2023控制器、EPEC2025可编程显示器，作为核心硬件以满足智能控制系统的功能要求和环境要求。利用GPS远程监控系统和GSM/GPRS远程无线通信系统实现远程控制，使之达到机群智能化施工的要求。
[Abstract]:Roller is an indispensable and efficient compaction machine in the construction of road and bridge. At present, there is a big gap between the domestic vibratory roller, especially the intelligent vibratory roller, in compaction quality and foreign similar products. The quality of compaction is directly related to the performance of the roller detection system and control system. Therefore, on the basis of analyzing the principle of intelligent vibratory roller at home and abroad, this paper studies the real-time detection system and intelligent control system of high performance and high level roller. It is useful for the research and development of high-end intelligent vibratory roller. In this paper, the related concepts and advantages of intelligent compaction technology are introduced, the application of intelligent compaction technology is introduced, and the dynamic model of "vibratory wheel-soil" is constructed on the basis of vibratory compaction mechanism. The dynamic model is simulated based on MATLAB/SIMULINK to verify the correctness of the theoretical analysis. The influence of the factors of the vibratory roller on the compaction effect is analyzed, and according to these factors and the present research situation, the key technology of the intelligent vibratory roller is put forward, that is, the compactness real-time detection system and the intelligent control system. On the basis of the new method of compactness measurement, this paper presents a real-time measurement technique of compactness by car, analyzes the advantages and disadvantages of the existing compactness evaluation methods, and aims at the linear and nonlinear characteristics of the vibration compaction process. This paper presents a compactness evaluation method based on multiple vibration characteristic parameters, studies the structure and working characteristics of the compaction roller with the function of real-time compactness detection, and extracts and processes the vibration acceleration signal in the compactness real-time measurement system and system. It provides a theoretical basis for the research and development of the real-time testing system of intelligent roller and the new compaction meter. According to the requirements of the intelligent control system and the overall function of the roller, the intelligent control design of the frequency modulation system, the amplitude modulation system and the driving speed system is carried out for the automatic control of the compaction parameters. Due to the complexity and uncertainty of the vibration compaction process, an intelligent compaction control scheme with fuzzy control is proposed. The CAN bus is used to realize the transmission of data information, and the special EPEC2023 controller is selected for EPEC2025 programmable display. As the core hardware to meet the functional requirements of intelligent control system and environmental requirements. The remote control is realized by using GPS remote monitoring system and GSM/GPRS remote wireless communication system to meet the requirement of intelligent construction of cluster.
