The invention discloses a construction equipment interactive operation method and system based on time phase independence, and the method comprises the steps: firstly obtaining an original track of a construction mechanical arm during operation, and carrying out the continuous processing; based on a spatial sampling algorithm, performing resampling on the continuous trajectory according to a set arc length step length, and eliminating time distortion and staying noise; the obtained sampling track is subjected to regularization; fitting the regularized track point set into a smooth geometric curve function; and finally, generating a time phase function according to a required working mode, generating a target trajectory in a time domain based on a geometric curve function, and realizing adaptive deployment under different component sizes. According to the method, the space arc length is used as a trajectory parameter, an independent variable is irrelevant to time, and the geometric trajectory established through equal-arc-length resampling and kernel function fitting can keep the space structure of the trajectory stable and unchanged. The trajectory and the time are thoroughly decoupled, and the trajectory robustness is higher.
