一、概述在煤炭地质勘探系统中实现“四个现代化”的重要措施之一,就是测井数字化。它对提高勘探质量,加快勘探速度,缩短勘探周期;进一步准确地探明我国煤炭储藏情况,更好地合理开发煤炭资源具有重要的意义。“数字测井磁带机与709机接口装置”就是把数字化测井的测量结果输送给计算机,从而在计算机中作数据处理的设备。“接口装置”的外形和结构如图1.1和图1.2所示。设备做成一个独立的机柜,全部元件分布在十一块双面印刷板上。图2画出了设备的逻辑框图。它由四部分组成。
I. Overview One of the important measures to realize the “four modernizations” in the coal geological exploration system is digitization of logging data. It is of great significance to improve the quality of exploration, accelerate the exploration speed and shorten the exploration cycle; to further accurately identify the coal storage in our country and to develop the coal resources more reasonably. The “Digital Logging Tape Drive and the 709 Machine Interface Unit” is a device that processes digital measurements of logs into a computer and processes the data in a computer. The outline and structure of “Interface Unit” are shown in Figure 1.1 and Figure 1.2. Equipment made of a separate cabinet, all components are distributed in 11 double-sided printing plate. Figure 2 shows the logical block diagram of the device. It consists of four parts.
