本文介绍的土动力三轴试验数据采集系统是一个具有较强功能的、通用的微型计算机系统。系统的硬件部分由CROMEMCO-Ⅱ型主机及磁盘驱动器、多路A/D转换输入接口部件和打印机组成。程序CHEESE是其软件的核心部分(其它程序如调试程序也存于软盘中)。该程序可在配有TU-ART板和D+7AI/O板的CROMEMCO-Ⅱ微机上运行,也可在以Z-80为cpu的其它微型机上运行。CHEESE能够完成模拟电信号的采样、转换、运算、结果打印、存贮等多方面的功能。该系统与土的动力试验设备配合、可以在短时间内处理大量数据,改善记录精度,为数据保存提供更好的手段,大大提高动力试验资料整理分析的功效。
This article describes the soil dynamic triaxial test data acquisition system is a powerful, universal micro-computer system. The hardware part of the system consists of CROMEMCO-Ⅱ host and disk drives, multi-channel A / D conversion input interface components and printers. The program CHEESE is at the heart of its software (other programs such as debuggers are also stored on floppy disks). This program can be run on a CROMEMCO-II microcomputer equipped with a TU-ART board and a D + 7AI / O board, or on other microcomputers that use the Z-80 as a cpu. CHEESE can complete the analog signal sampling, conversion, computing, the results of printing, storage and other functions. The system cooperates with soil dynamic test equipment to deal with a large amount of data in a short period of time, improve the recording accuracy, provide better means for data preservation and greatly improve the efficiency of dynamic test data collation and analysis.
