1. A conveying logistics line, comprising:
an unloaded pallet conveying line, wherein along an extension direction of the unloaded pallet conveying line, a plurality of workpiece manufacturing machines are sequentially distributed, the plurality of workpiece manufacturing machines comprise at least one first workpiece manufacturing machine and at least one second workpiece manufacturing machine that are alternately distributed, the unloaded pallet conveying line is connected to an input end of each of the workpiece manufacturing machines, and the unloaded pallet conveying line is configured to be capable of conveying unloaded pallets without workpieces to each of the workpiece manufacturing machines;
a first loaded pallet conveying line connected to an output end of each of the first workpiece manufacturing machines, wherein the first loaded pallet conveying line is configured to be capable of receiving and conveying loaded pallets with first workpieces from each of the first workpiece manufacturing machines;
a second loaded pallet conveying line connected to an output end of each of the second workpiece manufacturing machines, wherein the second loaded pallet conveying line is configured to be capable of receiving and conveying loaded pallets with second workpieces from each of the second workpiece manufacturing machines;
a merging conveying line connected to the first loaded pallet conveying line and the second loaded pallet conveying line, wherein the merging conveying line is configured to receive the loaded pallets from the first loaded pallet conveying line and the loaded pallets from the second loaded pallet conveying line according to a preset sequence;
a workpiece retrieval station, wherein an input end and output end of the workpiece retrieval station are respectively connected to an output end of the merging conveying line and an input end of the unloaded pallet conveying line; and
an electrical control module communicatively connected to the unloaded pallet conveying line and configured to control quantities of unloaded pallets conveyed by the unloaded pallet conveying line to each of the first workpiece manufacturing machines and each of the second workpiece manufacturing machines, based on real-time quantity information of the loaded pallets on the first loaded pallet conveying line and the second loaded pallet conveying line, so as to achieve a stable conveying state within a set operating time of the conveying logistics line, wherein the stable conveying state comprises the real-time quantity of loaded pallets on the first loaded pallet conveying line and the real-time quantity of loaded pallets on the second loaded pallet conveying line being within a first set range and a second set range respectively.
 
10. A pallet logistics control method applied to a conveying logistics line, wherein the conveying logistics line comprises:
an unloaded pallet conveying line, wherein along an extension direction of the unloaded pallet conveying line, a plurality of workpiece manufacturing machines are sequentially distributed, the plurality of workpiece manufacturing machines comprise at least one first workpiece manufacturing machine and at least one second workpiece manufacturing machine that are alternately distributed, the unloaded pallet conveying line is connected to an input end of each of the workpiece manufacturing machines, and the unloaded pallet conveying line is configured to be capable of conveying unloaded pallets without workpieces to each of the workpiece manufacturing machines;
a first loaded pallet conveying line connected to an output end of each of the first workpiece manufacturing machines, wherein the first loaded pallet conveying line is configured to be capable of receiving and conveying loaded pallets with first workpieces from each of the first workpiece manufacturing machines;
a second loaded pallet conveying line connected to an output end of each of the second workpiece manufacturing machines, wherein the second loaded pallet conveying line is configured to be capable of receiving and conveying loaded pallets with second workpieces from each of the second workpiece manufacturing machines;
a merging conveying line connected to the first loaded pallet conveying line and the second loaded pallet conveying line, wherein the merging conveying line receives the loaded pallets from the first loaded pallet conveying line and the loaded pallets from the second loaded pallet conveying line according to a preset sequence;
a workpiece retrieval station, wherein an input end and output end of the workpiece retrieval station are respectively connected to an output end of the merging conveying line and an input end of the unloaded pallet conveying line; and
an electrical control module communicatively connected to the unloaded pallet conveying line, wherein the electrical control module controls the unloaded pallet conveying line using the control method so that the conveying logistics line achieves a stable conveying state within a set operating time, the stable conveying state comprising a real-time quantity of the loaded pallets on the first loaded pallet conveying line and a real-time quantity of the loaded pallets on the second loaded pallet conveying line being within a first set range and a second set range, respectively; and
the control method comprises:
a real-time quantity information acquisition step: acquiring, by the electrical control module, real-time quantity information of the loaded pallets on the first loaded pallet conveying line and the loaded pallets on the second loaded pallet conveying line;
an unloaded pallet allocation step: controlling, by the electrical control module based on the real-time quantity information, quantities of unloaded pallets conveyed by the unloaded pallet conveying line to each of the first workpiece manufacturing machines and each of the second workpiece manufacturing machines.
