Wherein, the preset value of the compacted density is obtained through an experimental method.

When switching to the second control subsystem through the switch 43, the control steps of the second control subsystem include:

Step a, for detecting the deflection angle δ of the vibrator of the vibrating wheel of the road roller relative to the vertical direction;

Step b, use the formula Fv=meω ² cos(δ) to calculate the component force of the vibration wheel excitation force in the vertical direction, wherein m is the mass of the eccentric block, e is the eccentricity, ω is the angular velocity, ω=2πf, f for the vibration frequency to remain unchanged;

Step c, comparing the component force _Fv of the exciting force in the vertical direction with the preset value F of the compaction exciting force, when the component force Fv of the exciting force in the vertical direction is greater than the preset value of the compaction exciting force When the value F is set to ₀ , the vibrator of the vibrating wheel of the road roller is controlled to rotate so as to reduce the component force Fv of the exciting force of the vibrating wheel in the vertical direction until the component force Fv of the exciting force in the vertical direction is equal to the compaction excitation force. Vibration force preset value F ₀ ; when the component force Fv of the exciting force in the vertical direction is less than the compaction exciting force preset value F ₀ , the vibrator of the vibrating wheel of the road roller is controlled to rotate to increase the exciting vibration of the vibrating wheel The component force of the force in the vertical direction until the component force Fv of the excitation force in the vertical direction is equal to the preset value F ₀ of the compaction excitation force.
