一种孔压静力触探数据采集系统

Data acquisition system of piezocone penetration test(CPTU)

从实现孔压静力触探多种测量功能和自动测量与数据记录的要求出发,开发了一套孔压静力触探数据采集系统,并完成了TCY-1型测试仪以及PC机配套软件的设计与调试;介绍了其组成单元、工作原理与流程。系统具有测量精度高、数据容量大、体积小和功耗低等特点。应用表明,系统操作简便、配置灵活、工作效率高,可以广泛应用于工程勘测领域。

This paper presents the data acquisition system of piezocone penetration test （CPTU）. The construction units and working principle of the system axe introduced in detail. The functions of the system include testing-data acquisition and saving and displaying in CPTU. Because of the advantages of the system high precision, large memory amount, small size, low power consuming and so on, it will be widely used in engineering exploration filed.
