本文叙述了在IBM-PC-XT微机上实现爆炸地震模拟磁带记录的A/D转换及处理系统,该处理系统具备多种功能:采样、存盘、回放、CRT显示原始记录、CRT上直接读取波至、打印机上输出记录、解译二进制偏移码、数据予处理、绘制记录截面图、滤波处理和频谱分析等。该处理系统对MCP-1型和MCD-3型的解调器均适用,不仅在室内.而且也适合野外工作,这为野外爆炸地震模拟磁带记录的现场采样、处理、解释提供了简便、省时的有效途径,同时,由于该系统采样频率的可控性,故也适合于其他的用途。
This paper describes the A / D conversion and processing system for the explosion seismic analog tape recording on the IBM-PC-XT microcomputer. The processing system has many functions such as sampling, saving, playing back, original recording of CRT display, direct reading on CRT Wave to, the printer output records, interpret the binary offset code, data to be processed, draw the recording cross-section, filtering and spectrum analysis. The system is suitable for both MCP-1 and MCD-3 modems, not only indoors but also for field work, providing an easy, on-the-spot sampling, processing, and interpretation of field-blast seismic analogue tape records, When the effective way, at the same time, due to the system sampling frequency controllability, it is also suitable for other purposes.
