【摘要】:中央控制軟件是大型地震資源勘探裝備的核心控制與管理環(huán)節(jié),承擔著分布式地震波采集系統(tǒng)的控制、地震采集數(shù)據(jù)的預處理、地震采集數(shù)據(jù)庫的管理以及勘探裝備運行控制等重任,是研制大型地震資源勘探裝備的主要研究內(nèi)容之一。本文介紹了陸用大型拖曳式地震勘探系統(tǒng)的總體結(jié)構(gòu)及中央控制軟件的主要功能,確定了軟件總體設計方案及開發(fā)平臺,在此基礎(chǔ)上完成了系統(tǒng)初始化、數(shù)據(jù)傳輸、地震數(shù)據(jù)的格式標準化轉(zhuǎn)換及數(shù)據(jù)庫等功能模塊的設計,實現(xiàn)了中央控制軟件的主要功能。鑒于廢道的自動處理在地震數(shù)據(jù)預處理中有著廣泛的使用價值,本文基于BP神經(jīng)網(wǎng)絡開展了廢道自動處理的探索性研究,分別從樣本選取、特征參數(shù)提取、神經(jīng)網(wǎng)絡結(jié)構(gòu)設計等方面設計了基于BP神經(jīng)網(wǎng)絡的廢道自動處理方法,通過仿真驗證初步實現(xiàn)了BP神經(jīng)網(wǎng)絡的廢道自動處理。在上述工作的基礎(chǔ)上,對中央控制軟件和廢道自動處理算法進行了測試研究,測試結(jié)果表明中央控制軟件運行穩(wěn)定,實現(xiàn)了所要求的主要功能;基于BP神經(jīng)網(wǎng)絡的廢道自動處理方法具有一定的可行性。
[Abstract]:The central control software is the core control and management link of large-scale seismic resources exploration equipment. It is responsible for the control of distributed seismic wave acquisition system and the preprocessing of seismic acquisition data. The management of seismic acquisition database and the operation control of exploration equipment are one of the main research contents in the development of large-scale seismic resources exploration equipment. This paper introduces the overall structure of large towed seismic exploration system for land and the main functions of the central control software, and determines the overall design scheme and development platform of the software. On this basis, the system initialization and data transmission are completed. The main functions of the central control software are realized by the design of the functional modules such as the standardized transformation of seismic data format and database. In view of the extensive application value of automatic disposal of waste track in seismic data preprocessing, this paper carries out exploratory research on automatic disposal of waste track based on BP neural network, which selects samples and extracts feature parameters, respectively. The automatic disposal method of waste track based on BP neural network is designed in the aspect of neural network design, and the automatic disposal of waste road based on BP neural network is preliminarily realized by simulation verification. On the basis of the above work, the central control software and the automatic processing algorithm of waste road are tested and studied. The test results show that the central control software runs stably and achieves the required main functions. The automatic disposal method based on BP neural network is feasible.
