井下通用数据采集与控制系统

提出了一种由单片机构成的半双工井下数据采集与控制系统。这个系统针对数控测井系统的井下通信规程,以单片机下井的方式,代替井下仪器的专用接口和数据采集部分,使之具有通用性强、可靠性高和成本低等特点,并为测井仪器向现代化以及现场直观实时解释软件提供了可能。

General Data Acquisition and Control System of Downhole Logging Tool

A half duplex data acquistion and control System of logging tool is made up of chip microprocessors which have the same function as the special interface and data acquisition system of the original downhole tools. Thus, it has wider uses, more reliabilities and lower costs, and also opens up possibilities for in-situ realtime software interpretation.
