录井绞车模块的研制

Development of a new type winch counting module used in mud logging

设计了一种新型的绞车计数模块 ,采用计数器 82 5 3,处理器 89C5 1,信号转换器MAXIM4 85等 ,成功地实现了绞车的计数测量 ,并通过 4 85总线传输 ,有效地抑制了干扰 ,可较好地在录井现场运行。该模块具有设计简单 ,使用方便 ,驱动能力强的优点。

A new type winch counting module is developed by using the 8253 PIT, 89C51 CPU and 485 interface. The winch counting signal can be accurately measured and transferred with the 485 Bus. Because of its low noise, it can be used in the field for the mud logging. This module is of simple design, convenient use and powerful drive.
