A SEISMIC EQUIPMENT FOR SHALLOW EXPLORATION WITH ENHANCED SIGNAL TO NOISE RATIO, TYPE ZD-1

  • 摘要: 本仪器用于探测地表以下几十米至数百米范围内的介质构造。通过对信号波形的迭加处理,达到改善信噪比的目的。 该仪器采用8位大规模集成单片A/D转换器,取样速度为5000,2000,1000和500样值/秒。內存尺寸为1024字×8位.机内设有延迟电路,合理选用可提高内存效能.信号记录采用模拟和数字编码两种方式.具有轻便、功耗低、量程范围大和时间精度高等特点.该仪器在野外试验中取得较好的结果.

     

    Abstract: This equipment can be used to investigate the structure of shallow layers, ten to several hundred meters below surface. By stacking the wave signals in processing the data, it has been possible to improve the signal-to-noise ratio.Bight-bit monolithic large scale integrated circuit A/D coverter is employed. Speeds of sampling are 500, 1000, 2000, 5000 per second respectively. The storage capacity of this equipment is 1024×8 bits. By means of delay circuits it is possible to increase the efficacy of storage.Analog and digital codes are used in recording wave signals. This seismic outfit has high portability, low power consumption, wide dynamic range and high time accuracy etc. Satisfactory results have been obtained in the field.
