【摘要】：面对日益枯竭的陆地资源及来自对能源需求日益增长的压力，海洋资源开始为各国所关注，也成为各国发展经济的重要战略基地。随着海洋油气勘探技术的迅速发展，CSEM方法在海洋油气勘探中受到广泛重视和关注。国外研究机构及相关油气公司应用可控源电磁勘探的方法在技术研发、设备制造方面已经达到实用化水平，但是国外对于海洋油气勘探只提供相关技术服务不提供设备。国内开展海洋可控源电磁勘探方法起步比较晚，设备仪器制造方面与国外还有一段距离。因此研制具有自主知识产权的海洋可控源电磁勘探仪器设备成为当前的重要任务。本论文研究内容依托国家高技术研究发展计划（863计划）课题“海洋可控源水下系统装备研制和理论研究”和山东省科技发展计划课题“深海电场观测系统关键技术研究”，围绕CSEM的相关方法，根据现场工程作业的需求和方便海上作业现场的施工以及为满足部分仪器的授时、校时等特殊要求，设计并实现了功能较为完善的甲板移动操控仪。本论文介绍了甲板移动操控仪的功能定义、系统整体规划、硬件电路设计、软件设计、人机操作界面的规划及设计。甲板移动操控仪主要功能包括：采集站的设备管理，GPS授时校时，采集站设备的唤醒、启动采集、停止采集、睡眠，采集站设备参数的设置，采集站设备下水前采集信息显示监测、采集站设备采集的信息高速导出存储、采集信息的联网上传。系统控制器采用的是意法半导体公司的STM32F系列处理器。针对海底采集站时钟同步工作的要求，采用了GPS授时、校时方法。为方便海上现场施工作业，操作命令用无线电台发送，大量数据用联网的方式传输。针对电磁记录仪采集的大量数据要求快速导出的问题，采用高速的USB方法来实现。同时为保证数据快速、可靠的存储，硬件上采用STM32F207处理器提供的灵活静态存储控制器（FSMC）接口与外部存储介质CF卡相接，，软件数据存储上采用文件系统。在实现相关功能的基础上，为降低系统功耗，在器件选型上考虑功耗较低的芯片及模块，同时在设备中设置了正常工作模式、休眠模式。本文最后给出了甲板移动操控仪的相关实物图及系统联调测试的结果。测试结果表明，系统性能良好，人机交互界面操作灵活，可有效管理海底采集站的相关设备及提高海上工程作业的效率。该系统的各项功能完全能达到海底采集站功能需求。
[Abstract]:In the face of the increasingly exhausted land resources and the increasing pressure from the increasing demand for energy, the marine resources have been concerned by all countries and become an important strategic base for the development of national economy. With the rapid development of offshore oil and gas exploration technology, CSEM method has received extensive attention and attention in offshore oil and gas exploration. Overseas research institutions and related oil and gas companies have applied controllable source electromagnetic exploration methods to the technical research and development, equipment manufacturing has reached a practical level, but overseas for offshore oil and gas exploration only provide related technical services do not provide equipment. The method of ocean controlled source electromagnetic exploration in China started late, and the manufacture of equipment and instrument is still far away from foreign countries. Therefore, the development of marine controllable source electromagnetic exploration equipment with independent intellectual property rights has become an important task. The research content of this paper is based on the National High Technology Research and Development Program (863 Program), "equipment Research and theoretical Research of Marine controllable Source underwater system", and Shandong Province Science and Technology Development Program project, "Research on key Technologies of Deep Sea Electric Field observing system". According to the demand of field engineering and the convenient construction of offshore operation, and to meet the special requirements of some instruments, such as timing and calibration, a deck moving control instrument with perfect function is designed and realized around the relevant methods of CSEM. In this paper, the function definition, the whole system planning, the hardware circuit design, the software design, the man-machine operation interface plan and the design of the deck mobile controller are introduced. The main functions of the deck mobile controller include: the equipment management of the acquisition station, the GPS timing, the awakening of the acquisition station equipment, the starting of the acquisition, the stopping of the acquisition, the sleep, the setting of the equipment parameters of the acquisition station, The data collected from the collecting station is exported and stored at high speed, and the collection information is uploaded online. The system controller uses the STM32F series processor of Italian semiconductor company. According to the requirements of clock synchronization in submarine acquisition station, GPS timing and timing correction method is adopted. In order to facilitate the construction operation, the operation command is transmitted by radio station, and a large amount of data is transmitted through the network. To solve the problem that a large number of data collected by electromagnetic recorder need to be exported quickly, a high speed USB method is adopted. At the same time, in order to guarantee the fast and reliable storage of data, the flexible static storage controller (FSMC) interface provided by STM32F207 processor is used to connect with the external storage medium CF card, and the file system is used in the software data storage. Based on the realization of related functions, in order to reduce the power consumption of the system, the low-power chips and modules are considered in the device selection, and the normal working mode and the sleep mode are set in the device at the same time. At the end of this paper, the related physical diagram of deck moving controller and the test results of system alignment are given. The test results show that the system has good performance and flexible man-machine interface operation. It can effectively manage the relevant equipment of submarine acquisition station and improve the efficiency of offshore engineering operations. All functions of the system can meet the requirements of submarine acquisition station.
