摘要
详细介绍了便携式数控测井数据采集系统脉冲计数面板的设计,其中硬件电路采用模块化设计方案,对脉冲信号的处理采用了自动增益控制电路、自动门槛电路以及迟滞比较电路。该面板结合井下脉冲信号及电缆进行测试,结果证明,该面板具有较好的适应性,抗干扰性强,达到了实际工作的需求。
This article detailedly introduces the design of pulsed counting device of portable numerical logging ground data acquisition system. The hardware system adopts module structure, and the processing of pulsed signal consists of auto-amplification circuit, auto-threshold circuit and noninverting comparator with hysteresis. This device is tested with pulsed signal and cable simulator and it is proved successfully that this device has good applicability, antijamming and satisfies with the real circumstance demand.
