The invention relates to the technical field of beam transporting vehicle walking systems, in particular to a beam transporting vehicle energy-saving control method and system based on working condition classification. Under different working conditions of the girder transporting vehicle, linear coupling control can be carried out on the rotating speed of the diesel engine and the displacement of the hydraulic system at the same time, the displacement of the hydraulic system is matched with the power of the diesel engine, and compared with a fixed rotating speed control mode of a traditional girder transporting vehicle, the problem that the displacement of the hydraulic system is low can be effectively solved. The problem of over-high rotating speed of the diesel engine is solved, so that energy loss and waste are avoided; the working conditions of the beam transporting vehicle under different conditions are distinguished, the rotating speed of the diesel engine under different working conditions is adjusted in real time through linear coupling control over the displacement of the diesel engine and the pump, the energy utilization efficiency of the beam transporting vehicle can be greatly improved, the overall using economical efficiency of equipment is improved, and the application prospect is wide.
