1. A test system for continuously and intelligently measuring water content of subgrade in real-time, equipped with a wheeled machine comprising a scroll roller to detect water content of subgrade according to electrical resistivity theory, the system comprising:
at least a set of electrodes comprising four probes, whereby detection parts of the four probes are linearly and equidistantly arranged on the scroll roller, and the arrangement direction of the detection parts of the four probes being parallel to an axis of the scroll roller;
a data integration apparatus respectively connected to the four probes and configured to be used for data acquisition, analysis and transmission; and
an electric source connected to the data integration apparatus for providing a working current,
wherein the wheeled machine is a road compacting machine, the scroll roller is a scrolled wheel of the road compacting machine used for compacting a roadbed, and the data integration apparatus and the electric source are located inside the scroll roller.
