具有串行通讯能力的深度测试仪

Depth Test Instrument Provided with Ability of Serial Communication

根据油田测井技术现状 ,设计了一种以 89C5 2单片机为核心的深度测试仪。单片机对安装在测试滑轮上的光电编码器输出的脉冲进行计数 ,将计得的脉冲数转换成深度值 ,运算出测井速度 ,并显示这两个值 ;同时也可将深度值通过接口传递给计算机系统。文中介绍了深度测试仪的原理给出了硬件原理图和软件框图。

According to actual states of oil field,the author designed a kind of the depth test instrument using 89C52 singlechip as core.The pulses of the photoelectric coder installed on test block and tackle were counted by singlechip,the singlechip changed counts to depth and computed logging speed and sent them to show or to computer system through RS-232 interface.This paper introduced hardware principle of the depth test instrument and gave principle figure and software flow chart.
