Abstract

This study proposes detection methods of vehicular soil compaction degree based on a series of ideal conditions and GIS, which is to reflect the soil compaction degree and soil moisture through measuring the variation of acceleration amplitude of vibrating compaction wheels, in combination with the mathematical model of “vibrating drum-soil” two-degree-of-freedom vibrating system based on the analysis of the operating principle of vehicle; designs an embedded system based on ARM and modules such as the collection, processing and transmission of acceleration signals; writes application programs of system software in μC/OS-II environment; and develops a new detector of soil compaction degree. Experimental results show that this detection system can meet the requirement of comprehensive real-time monitoring for the soil compaction degree and soil moisture.
