A contact type rolling machine integrated compaction sound wave detection system comprises a sound emission sensor, an industrial personal computer, a data acquisition instrument, a GPS / BDS receiver and the like, when a filling layer is rolled, a sound wave field time domain signal formed near the rolling layer is received by the sound emission sensor vertically installed on a support directly connected with a vibration wheel, and a sound wave field digital signal is formed through sampling; meanwhile, the GPS / BDS receiver provides a space signal related to a rolling position, filtering and spectral analysis are carried out on the sampled sound wave signal, an effective sound signal harmonic amplitude is obtained, a contact type sound compaction index is established according to the correlation between the amplitude ratio and the compaction degree of the filling material, and a space-time compactness distribution diagram of a rolling area is displayed on an airborne display in combination with GPS space position information. The system has the advantages of being accurate, continuous, real-time, small in discreteness, low in cost and the like and is suitable for continuous compaction quality control of filling materials, and the intelligent continuous compaction function can be easily achieved by controlling operation parameters of the rolling machine through compaction degree feedback.
