【摘要】：隨著起重機械在港口、風電、化工等大型建設工程中的廣泛應用，人們對吊裝方案設計的準確性、高效性和可靠性要求越來越高。目前吊裝方案的制定一般以人工完成為主，存在可行性得不到驗證、對資源的利用得不到合理安排等不足。針對這些不足，本文以我校與中聯(lián)重科合作開發(fā)的全地面起重機大型吊裝工程方案規(guī)劃系統(tǒng)為背景，研究和實現(xiàn)了起重機吊裝工況選擇專家系統(tǒng)。 起重機吊裝工況選擇專家系統(tǒng)是全地面起重機大型工程吊裝方案規(guī)劃系統(tǒng)中的一個子模塊。從系統(tǒng)的設計思路、設計參數(shù)及設計要求三個方面分析了吊裝工況選擇專家系統(tǒng)的需求。構建了起重機工況選擇專家系統(tǒng)的整體結構，，為系統(tǒng)設計了專家系統(tǒng)核心功能、界面操作、基本操作共三個主要模塊包，其中專家系統(tǒng)核心模塊包由知識庫、推理機、綜合數(shù)據(jù)庫。采用產(chǎn)生式表示法，建立了包括實例庫和規(guī)則庫的知識庫，采用正向推理的基本思想實現(xiàn)了系統(tǒng)的推理機制，建立了支持整個方案規(guī)劃系統(tǒng)的綜合數(shù)據(jù)庫。研究和實現(xiàn)了吊裝工況選擇的關鍵參數(shù)計算，包括虛擬場景信息數(shù)據(jù)的自動獲取，起重機作業(yè)半徑、起吊高度、起重量、倍率等因素的校核以及運動保護的計算。 基于以上研究，將本文開發(fā)的起重機吊裝工況選擇專家系統(tǒng)嵌入全地面起重機大型吊裝工程方案規(guī)劃系統(tǒng)中，并在企業(yè)獲得成功應用，驗證起重機工況選擇專家系統(tǒng)選擇的吊裝工況的正確性和可行性。
[Abstract]:With the wide application of hoisting machinery in port, wind power, chemical engineering and other large-scale construction projects, people demand more and more high accuracy, efficiency and reliability for the design of hoisting scheme. At present, the design of hoisting scheme is mainly done manually, and the feasibility can not be verified and the utilization of resources can not be reasonably arranged. In view of these shortcomings, this paper studies and implements an expert system for crane hoisting condition selection based on the scheme planning system of large-scale hoisting engineering for all ground cranes developed jointly by our university and Zhonglian heavy department. The expert system for crane hoisting condition selection is a sub-module in the hoisting scheme planning system of the whole ground crane. The requirements of the expert system for the selection of hoisting conditions are analyzed from three aspects: the design idea, the design parameters and the design requirements. The whole structure of the crane operating condition selection expert system is constructed, and three main module packages are designed for the system, such as the core function of the expert system, interface operation and basic operation, in which the core module package of the expert system is composed of knowledge base, reasoning machine, and so on. Comprehensive database The knowledge base including case base and rule base is established by using production representation. The reasoning mechanism of the system is realized by using the basic idea of forward reasoning, and a comprehensive database supporting the whole scheme planning system is established. The key parameter calculation of hoisting condition selection is studied and realized, including the automatic acquisition of virtual scene information data, crane operation radius, lifting height, lifting weight, ratio and so on, as well as the calculation of motion protection. Based on the above research, the crane hoisting condition selection expert system developed in this paper is embedded in the whole floor crane large-scale hoisting project planning system, and has been successfully applied in the enterprise. Verify the correctness and feasibility of hoisting condition selected by the crane working condition selection expert system.
