The invention relates to the technical field of block chains, in particular to an assembly line consensus protocol based on inter-fragment cooperation in a block chain system, which realizes distributed cross-fragment verification based on 3PC (3rd Personal Computer) by using submission intention and submission proof, so that the system obtains higher security, and the user experience is improved. The ticket right of the Byzantine node in one fragment at most can be tolerated to exceed one third of the total ticket right of the fragment; the overall security of the fragmentation system is improved through a cross validation mechanism, the same number of nodes can be distributed to more fragments under the condition that the security hypothesis is the same as the traditional non-cooperative consensus protocol, and the expandability of the system is improved; according to the method, data required by cross validation is packaged by using assembly line blocks, so that an aggregation signature generated by each round of element voting can be used as QC of different stages of continuous six blocks, the average submission overhead of each block is reduced to one round of voting, and the additional consensus overhead brought by a cross validation mechanism is counteracted to a certain extent.

The method includes: establishing the mechanical motion equations of a coal unloading crawler device; the coal unloading crawler device consists of a chain system, a scraper bucket, a tensioning mechanism, a drive motor, and a main frame; establishing a hyperlocal model of the coal unloading crawler device based on model-free control theory and rewriting the extended state equations; addressing the limitations of the finite difference method by introducing an extended state observer to estimate all unknown dynamics in real time; and introducing a compensation function to construct an improved extended state observer, correcting estimation errors, thereby designing a model-free controller.
