摘　　要：在借鉴传统检测方法的基础上,根据压路机振动信号与压实程度的相关关系,提出了一种随车压实度实时检测系统。该系统利用振动传感器采集压路机振动信号,并将该信号进行A/D转换,放大、滤波,在时域和频域进行数字信号处理,进而提取出压实度实时数值。通过大量现场试验验证,本系统计算出的压实度值与传统压实度检测结果,具有高度的一致性和准确性。Abstract： Based on traditional detection methods and according to the relationship between roll＇s vibration signal and compaction, a real-time on-vehicle compaction detection method was put forward. This system collected vibration signal and changed it to digital mode, then amplified, filtered and processed it in time and frequency field to get the real-time compaction value. After a large number of field tests, the results obtained by this system shows high consistency and accuracy to the traditional methods.
