可控震源检测数据采集系统研制

Development of the Data Acquisition System for Detecting Vibrators

可控震源在地震勘探中得到了广泛应用,为了检验可控震源系统工作状态,通常需要采集可控震源电控箱体的参考信号、TB信号、平板加速度信号、重锤加速度信号,计算出震源的出力信号并由软件分析震源机械系统的各种状态信息,确保可控震源工作正常。文章给出了一种可控震源检测数据采集系统的硬件设计,加速度传感器选型。测试验证表明设计的数据采集系统可以应用于可控震源系统工作状态数据采集。

The vibrator has been widely used in seismic exploration, in order to test the working condition reliability of the vibrator system, the reference signal, TB signal, base plate acceleration signal and mass acceleration signal of the electronic-controlled box are collected to calculate the force signal, and the vibrator system status information is be analyzed by the software, to make sure the vibrator works proper- ly. The hardware design of a data aquisition system for detecting the vibrator is presented, and the model of the acceleration transducer is confirmed. The data acquisition system for detecting the vibrator is developed and tested, and detecting verification show the data acquisition system designed can be applied to the vibrator detection.
