摘要
介绍了高分辨率声波测井仪，时差信息处理系统的研制及工程实现采用单片机作为核心单元，使其智能化程度大大提高Ａ／Ｄ，Ｄ／Ａ采用１２位分辨率的ＡＤ５７４Ａ和ＤＡＣ１２１０，使系统高精度、高速度达到统一采用８２５３可编程定时／计数器，用独立振荡器向ＣＬＫ提供计数时钟，大大提高了计时精度，合理设定了门控单元的开门、关门时间，使系统抗干扰能力进一步加强，扩展了串行通讯，键盘操作与显示接口等，与上位系统机通讯，可实时打印时差曲线。
In this paper,the design and realization of a time difference information processing system for high-sonic well-logging instrument is presented.The 8031 computer and AD574 and DAC1210 are applied to the system,so that intelligence and precision and computing speed of the system are well improved. It is shown by test that the system is satisfactory.
