Description

Cableway transportation operation pre-permission and loading optimization method, system, medium and processor based on digital twin and real-time simulation Technical Field The invention relates to the technical field of cableway transportation, in particular to a digital twinning and real-time simulation-based cableway transportation operation pre-permission and loading optimization method, a system, a medium and a processor. Background Cableway transportation is used as a special freight transportation mode suitable for complex terrains (such as mountain areas, valleys, hills and the like), and is widely applied to the fields of electric power construction, mining, scenic spot material transportation, forestry transportation and the like. The cable system erected in the air is used for carrying transport carriers (such as hanging baskets and containers) to run along a given line, so that the limitation of inconvenient ground traffic can be effectively overcome, and point-to-point efficient transport is realized. However, cableway transportation operations are also accompanied by significant security risks and management challenges: First, the security risk is high. The cableway system is exposed to a field changeable environment for a long time, and is obviously influenced by natural factors such as wind load, temperature change, ice and snow accumulation and the like. In the transportation process, if the material is loaded unreasonably (such as offset of gravity center, overload and unstable fixation) or encounters extreme weather, dangerous conditions such as large swing of the carrier, overrun of stress of a rigging, unbalanced stress of a bracket and the like are easily caused, and even serious accidents such as rope disengagement and load falling are caused. At present, the safety evaluation before operation depends on manual experience and static calculation, so that the coupling effect of multiple physical fields and random environment interference in actual transportation are difficult to comprehensively and dynamically simulate, and the accurate early warning and quantitative evaluation of potential risks cannot be performed. Secondly, the loading scheme relies on experience and lacks scientific optimization. The existing loading operation is generally characterized in that an operator arranges the material placement sequence and the material placement position according to experience, and a unified and standard digital instruction is lacked. For the combination of materials with complex forms and heterogeneous mixing, an optimization scheme which not only meets the safety constraint but also gives consideration to the space utilization rate and the transportation efficiency is difficult to be quickly given by people. Especially when dealing with novel material or special transportation task, no history experience can be circulated, and improper loading easily occurs, so that multiple trial assembly and reworking are required, and the operation efficiency and the economy are affected. Furthermore, the work permit flow is conventional and lacks a digitized closed loop. At present, the license management of cableway transportation operation is mostly paper approval or simple electronic record, and is disjointed with actual loading scheme, simulation verification and risk control. The method can not dynamically and safely verify a specific loading scheme and generate an electronic pre-license with data support before operation, and is difficult to automatically trigger an optimization flow when the scheme does not pass, so that the management efficiency is low and the traceability is poor. Therefore, the prior art lacks an integrated method and system capable of performing high-precision, dynamic simulation and safety evaluation on the whole cableway transportation process before operation, automatically optimizing a loading scheme based on an evaluation result and generating digital operation permission. The security, efficiency and management level of cableway transportation operation are difficult to be systematically improved, and urgent requirements of modern engineering on intelligent and fine operation cannot be met. In view of the foregoing, there is a need for a method, system, medium and processor for pre-licensing and loading optimization of cableway transportation based on digital twinning and real-time simulation to solve the above-mentioned problems. Disclosure of Invention Aiming at the problems that the safety, efficiency and management level of cableway transportation operation are difficult to be systematically improved and the urgent requirements of modern engineering on intelligent and fine operation cannot be met in the prior art, the invention provides a digital twin and real-time simulation-based cableway transportation operation pre-permission and loading optimization method, system, medium and processor, which can systematically improve the safety, efficiency and managemen
