| 摘 要： | 通过对传统的静力触探数据采集系统进行改进,介绍了利用数据采集卡采集静力触探的压力数据,利用地上数据采集仪采集静力触探深度数据,数据采集过程中均运用时钟信息进行时间先后顺序和数据的同步匹配,通过数据存储模块可将数据存储下来,也可串行传输后把压力和深度数据通过液晶模块显示出来,最后将数据传入上位机管理系统中进行数据的综合处理,并将最终触探曲线显示出来。整个过程具有无缆化、采集精度高、集成度高、存储量大、经济便捷等特点,最后通过现场试验验证了改造后的静力触探数据采集系统的适用性。

| Abstract: | By the improvement on the traditional CPT data acquisition system, the paper introduced the collection of CPT pressure data using data acquisition card. The ground data acquisition instrument is used to collect the range data and the process of data collection is carried out with clock information to match in time sequence and data. The data can be stored with the data storage module and also can be displayed through the liquid crystal display module after the serial transmission. After integrated processing, the data were put into the host computer management system and the final data curve of CPT can be displayed. There are many characteristics in the whole process, such as wire-less, high precision of acquisition, high integration, large storage and being economic and convenient. The improved CPT data acquisition system is verified applicability through field experiments at last. |
