基于数据采集卡的无缆静力触探仪的研制与应用
|
摘要
静力触探作为土体原位测试技术的一种,它能够在不扰动土层的情况下,提供土层和土力学参数,其快速、准确的优势被国内外广泛应用。以传统的静力触探为基础,不断进行静力触探的优化改造,从而形成新的静力触探技术,是国内外的发展趋势。
本文介绍了基于数据采集卡的无缆静力触探仪的研制与应用,针对目前静力触探仪存在的问题,将现有的压力数据采集系统简化成数据采集板卡植入探头外接探杆内,深度信号由绝对式光电编码器直接采集数字量,分别由单片机控制整个系统的采集流程,建立了无缆化的数据采集与存储,通过数据采集卡的同步启动开关开始现场试验。单片机外接的存储芯片内的试验数据可通过板卡上的RS232接口电路与PC机的串口相连进行数据的传输,将数据导入PC机后通过公式换算实现数据的处理及运用相应软件进行静力触探曲线图的绘制打印。
将改造后的静力触探仪进行现场试验并收集指定孔位的静探数据,将数据串行导入电脑中进行整理,并利用华宁软件生成静探成果曲线图,它对现场地层的分层结果跟利用钻孔取样和室内试验的分层结果基本相对应。本静力触探仪方便、快捷,减少了人力和工作程序,有良好的应用和推广前景。
CPT as a kind of in situ soil testing technology can provided soil and soil mechanics parameters in the case of undisturbed soil.The advantages of quick and accurate take it be widely used domestic and abroad. The traditional basis of CPT what continuous optimization of CPT transformation and creating new CPT technology is the trend domestic and abroad.
This article describes the development and application of non-cable CPT equipment based on data acquisition card. For the current instrument problems, make the Existing pressure data acquisition system to Simplify the data acquisition board which implanted probe what is external probe rod, the digital of the depth signal is direct acquisition from the absolute optical encoder. Which is controlled by the MCU of the whole system acquisition process.It establish the non-cable data acquisition and storage. Field test is start through synchronous starting switch of data acquisition card Test data of MCU external memory chip through the RS232 interface circuit of board transfer to PC of serial port. After the data importing into PC, it converted by the formula used for data processing and the corresponding CPT software and plotting of print.
After the transformation of the CPT equipment it hold the field tests and collect the CPT dats of the designated holes. The datas are serial input the computer to organize and use the Huaning software to generate static probe curve. Stratified the results of its on-site formation basicly correspond to use drilling with sampling and laboratory test results. The CPT equipment have good application and promotion prospects because it is convenient and fast which reducing man labor and procedures.
