【摘要】：多通道井间地震观测系统作为一个完整的数据采集系统,包含了地震波的激发,地震波的采集以及对采集数据的处理与分析。系统中的震源取用了便携式电火花震源,采集模块采用了基于C8051F060的高速AD采集器,本文将重点阐述了这两部分的设计。在便携式电火花震源的设计上主要考虑了工频充电与变频高压充电以及对电火花的能量检测和电压闭环控制。便携式电火花的硬件部分不仅仅涉及到电子电路的硬件模块的设计和各个模块的器件选择还涉及到机械零部件的设计与组装问题。在震源的机械部件设计上我们利用Solidworks三维设计软件对内部的整体进行模拟拼接,根据每个元器件的实际尺寸设计结构图,然后再进行模拟组装,以达到在仪器外部达到三维可视化的效果。而在多通道采集仪的设计上利用了C8051F060单片机片内的16位高精度A/D,实现了0--5V的标准电压信号的高精度测量。采集仪的设计中同样包含了对C8051F060单片机的各个接口电路的设计和焊接布线等硬件方面的考虑而且还要对C8051F060单片机的数据采集过程进行软件编程和调试运行。除此之外,本文对于整个系统的震源部分和采集部分的性能进行了系统同步处理和联机测试,进而使观测系统取得了有效的数据,经过多次重复采集验证系统具有很好的稳定性和一致性。
[Abstract]:As a complete data acquisition system, multi-channel cross-well seismic observation system includes excitation of seismic wave, acquisition of seismic wave, processing and analysis of acquisition data. The portable EDM source is used in the system and the high speed AD collector based on C8051F060 is used in the acquisition module. The design of these two parts will be emphasized in this paper. In the design of portable spark source, the power frequency charge and frequency conversion high voltage charge, the energy detection and voltage closed loop control of electric spark are considered. The hardware part of portable EDM involves not only the design of electronic circuit hardware module and the device selection of each module, but also the design and assembly of mechanical parts. In the design of the mechanical components of the earthquake source, we use the Solidworks 3D design software to simulate and assemble the internal whole, design the structure diagram according to the actual size of each component, and then carry on the simulation assembly. In order to achieve the effect of three-dimensional visualization outside the instrument. In the design of multi-channel acquisition instrument, the 16-bit high precision A / D of C8051F060 single chip microcomputer is used to realize the high precision measurement of 0--5V standard voltage signal. The design of the collecting instrument also includes the design of the interface circuit of the C8051F060 single chip computer and the design of the welding wiring and so on. It also carries on the software programming and the debugging operation to the data acquisition process of the C8051F060 single chip computer. In addition, the performance of the source and acquisition parts of the whole system is synchronously processed and on-line tested in this paper, which makes the observation system obtain effective data. The system has good stability and consistency after repeated acquisition.
