脉冲计数类测井仪器处理系统的设计

Design of processing system of pulse logging tools.

设计一个对脉冲类测井仪器处理的简单系统 ,其中的硬件电路采用模块化设计 ,对信号的处理采用了自动增益和自动门槛 ,以及迟滞比较。该电路有较好的适应性 ,抗干扰能力强。同时给出与硬件配套的软件处理的几个简单程序。除了可以测脉冲频率外 ,还有专门测脉冲周期的电路。经过在江汉石油学院与江汉石油管理局仪表厂联合新研制的数控测井地面系统中的使用 ,表明该系统比较简洁实用 。

Design a system of processing pulse logging tool. Its hardware takes modularization. Signal processing system uses Auto gain, auto threshold and sluggish comparator. This circuit has better adaptability. Capability in anti interference is strong. It also shows a few simple program corresponding to its hardware. Besides measuring frequency of pulse, it has special circuit of measuring cycle of pulse. Used in computerized logging surface system,the system is proved to be relatively simple and practicable.
