【摘要】：壓路機是路橋建設(shè)施工中不可或缺的高效壓實機械，目前國內(nèi)振動壓路機，尤其是智能振動壓路機在壓實質(zhì)量方面與國外同類產(chǎn)品存在很大的差距，而壓實質(zhì)量的優(yōu)劣與壓路機檢測系統(tǒng)和控制系統(tǒng)的性能有直接關(guān)系。為此，本文在分析當(dāng)前國內(nèi)外智能振動壓路機原理的基礎(chǔ)上，研究高性能、高水平的壓路機實時檢測系統(tǒng)和智能控制系統(tǒng)，為高端智能振動壓路機的研究開發(fā)做了有益的探索和開拓性的工作。 文中首先對智能壓實技術(shù)的相關(guān)概念和優(yōu)點進行闡述，介紹了智能壓實技術(shù)的應(yīng)用；在振動壓實機理基礎(chǔ)上，構(gòu)建“振動輪-土”動力學(xué)模型，并基于MATLAB/SIMULINK對動力學(xué)模型進行了仿真，進一步驗證理論分析的正確性。分析了振動壓路機本身的因素對壓實效果的影響；根據(jù)這些因素，結(jié)合當(dāng)前的研究現(xiàn)狀，提出了振動壓路機智能化的關(guān)鍵技術(shù)，即壓實度實時檢測系統(tǒng)和智能控制系統(tǒng)。 在壓實度檢測新方法的基礎(chǔ)上，本文提出了隨車式壓實度實時檢測技術(shù)；分析現(xiàn)有的壓實度評價方法的優(yōu)缺點，針對振動壓實過程的線性特征和非線性特征，提出了基于多個振動特征參數(shù)的壓實度評價方法；研究具有壓實度實時檢測功能的壓路機的構(gòu)成和工作特點，壓實度實時檢測系統(tǒng)和系統(tǒng)中振動加速度信號的提取與處理，為智能壓路機實時檢測系統(tǒng)和新型壓實度儀的研究和開發(fā)提供了理論基礎(chǔ)。 根據(jù)壓路機智能控制系統(tǒng)的要求和實現(xiàn)的總體功能，針對壓實參數(shù)的自動控制，進行了調(diào)頻系統(tǒng)、調(diào)幅系統(tǒng)和行駛速度系統(tǒng)的智能控制設(shè)計。由于振動壓實過程的復(fù)雜和不確定性，提出了模糊控制的智能壓實控制方案，，采用CAN總線實現(xiàn)數(shù)據(jù)信息的傳輸，選用專用的EPEC2023控制器、EPEC2025可編程顯示器，作為核心硬件以滿足智能控制系統(tǒng)的功能要求和環(huán)境要求。利用GPS遠程監(jiān)控系統(tǒng)和GSM/GPRS遠程無線通信系統(tǒng)實現(xiàn)遠程控制，使之達到機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.
