【摘要】：随着国民经济的快速发展和人民生活水平的不断提高，人类对资源的需求不断加大，如何从地壳深部获得更多的资源是我国经济长远持续发展所面临的重点问题。地震勘探法在众多地球物理探测方法中具有探测深度大和精度高的特点，因此地震勘探法是当前深部探测最重要和有效的手段之一。有缆地震仪是目前国内外广泛应用的地震勘探仪器，但是大量的线缆使得其在野外布设困难，难以满足高密度、大道数、三维结构和复杂地形环境的深部资源勘探需求。无缆地震仪摆脱了沉重的电缆束缚，通过无线传输加自存储的工作方式完成地震勘探作业，这样能提高仪器在野外工作的灵活性，降低人力成本，然而由于其缺乏实时的远程监控手段，仪器在野外现场采集数据的质量难以得到有效的保证，所以无缆地震仪还没有被普遍推广应用。本文通过对无缆地震仪野外现场监控需求的分析，根据其对功耗、成本、实时性、可靠性和覆盖范围的要求，提出了基于北斗卫星通讯和GPRS网络通讯技术的无缆地震仪远程质量联合监控方案。本系统以ARM9处理器为核心控制器件，Linux嵌入式操作系统为应用软件设计平台，完成通信用户单元的软硬件设计。在系统中嵌入超低功耗的430协处理器，根据不同的施工阶段，远程控制仪器各个模块及仪器的工作状态，，最大限度的降低系统功耗。远程数据监控管理平台软件基于Microsoft Visual C++6.0软件设计平台编写完成，实现了同时对多台无缆地震仪的远程状态监测、运行过程控制、采集参数设置等功能，并能通过Google Earth地图显示软件，实时监测分析仪器的位置信息。通过在野外对无缆地震仪远程质量监控系统的性能指标和稳定性进行测试，验证了该方案的正确性与可行性。与国内外同类仪器相比，本系统的引入使得无缆地震仪具有监控覆盖范围广、施工调度灵活性高和仪器待机时间长等特点，同时仪器野外采集数据的质量也得到了有效的保证。
[Abstract]:With the rapid development of the national economy and the continuous improvement of the people's living standard, the demand for human resources is increasing. How to obtain more resources from the deep crust is the key problem in the long-term and sustainable development of our economy. So the seismic prospecting method is one of the most important and effective methods in the current deep exploration. The cable seismograph is a widely used seismic exploration instrument at home and abroad, but a large number of cables make it difficult to set up in the field. It is difficult to meet the requirements of deep resource exploration for high density, number of roads, three dimensional structure and complex terrain environment. The seismograph gets rid of the heavy cable tie and completes the seismic exploration operation through wireless transmission and self storage. This can improve the flexibility of the instrument in the field and reduce the cost of manpower. However, because of its lack of real-time remote monitoring means, the quality of the data collected in the field is difficult to be guaranteed effectively. So no cable seismograph has not been widely applied.
Based on the demand of field monitoring in the field of cable - free seismograph, based on the requirements of power, cost, real-time, reliability and coverage, a joint monitoring scheme for remote quality of cable - free seismograph based on Beidou satellite communication and GPRS network communication technology is proposed. This system is based on ARM9 processor as the core control device and embedded in Linux The software and hardware design of the communication user unit is completed for the application software design platform. The ultra low power 430 co processor is embedded in the system. According to the different construction stages, the working state of each module and instrument is remotely controlled, and the power consumption is reduced to the maximum limit. The remote data monitoring and management platform software is based on Micro. The software design platform of soft Visual C++6.0 is completed. It realizes the functions of remote state monitoring, operation process control, collection parameter setting and so on, and can monitor the position information of the analysis instrument in real time through the Google Earth map display software.
By testing the performance index and stability of the remote quality monitoring system of cable free seismograph in the field, the correctness and feasibility of the scheme are verified. Compared with the same kind of instruments at home and abroad, the introduction of this system makes the cable free seismograph with the characteristics of wide monitoring coverage, high flexibility in construction and long standby time of instrument and so on. The quality of field acquisition data has also been effectively guaranteed.
