Description

Fragile article logistics package kit with breakage early warning function Technical Field The invention relates to the field of logistics packaging, in particular to a fragile product logistics packaging kit with a breakage early warning function. Background At present, the transportation of high-value fragile products (such as precise instruments, artworks, high-end industrial parts and the like) mainly depends on an enhanced passive protection packaging scheme, such as customized thickened foam, a solid wood reinforced box body or a mechanical suspension damping system and the like, and the scheme can provide a certain degree of physical buffering, but the essence of the scheme still belongs to black box transportation, and in the whole logistics process, the key physical state parameters such as real stress, posture change, impact vibration frequency spectrum and the like born by the packaged internal articles are completely unknown. This lack of status information leads to serious management and liability dilemma in that when the shipment is completed and the case is opened to find the damage, the specific time node at which the damage occurs (such as in warehouse loading and unloading, long-distance shipment jolt or terminal sorting links) and direct causes (whether dumping, violent impact or resonance fatigue) cannot be traced back at all, and this uncertainty often causes long-term liability disputes between shippers, carriers, insurers and consignees, and the claiming process is lengthy and difficult. Therefore, the prior art has the obvious defects in the logistics field of high-value fragile products that on one hand, real-time and multidimensional accurate sensing and digital recording of the real physical state of the in-transit asset cannot be performed, and on the other hand, active early warning is more difficult to realize in the early stage of risk accumulation, and a decision basis for timely intervention cannot be provided for a logistics manager. This leaves the whole transportation process in an uncontrollable risk blind area, which makes it difficult to meet the high standard requirements of modern supply chains for transparency, traceability and active risk management. Disclosure of Invention In order to solve the technical problems, the invention aims to provide the fragile product logistics packaging kit with the breakage early warning function, so as to solve the technical problems that the existing passive packaging cannot monitor, early warn and record the state of the transportation environment in real time, so that the responsibility of goods loss is unclear and the risk is uncontrollable.
