摘要
土工布在工程应用中 ,其渗透率是一项重要的参考性能指标。该系统通过RS - 4 85总线连接上位机与 89C5 2单片机 (下位机 ) ,实现了土工布水平渗透率的自动测控系统。下位机具有自动加压 /水力梯度控制及渗透率计算功能。上位机与多个下位机通讯进行实时监测 ,并实现测试数据的报表打印、曲线绘制 ,提高了测量精度 。
Infiltration is an important performance index of geotextiles in projects application.It is realized automatic measuring and controlling system of geotextile in-plane infiltration by master computer linking slavers 89c52 single-chip computer through RS-485 bus.Every slaver computer can control pressures/hydraulic gradients and calculator infiltration rate.,and the master computer realize real time monitor/print test reports and draw curves through communicating slaver computers (6).It can improve the measuring precise and decrement the measuring time.
