[0002] Escalators are used to transport passengers up or down between different floors of a building. They are widely used in places with large crowds of people, such as railway stations, subway stations, bus stations, shopping malls, and airports. The working principle of escalators is a chain-type circulating conveyor belt, which is a forced drive. Therefore, once it gets stuck, it may cause damage to the equipment. In addition, its moving parts are exposed to the outside and in direct contact with people, which poses a huge safety hazard.

[0003] The existing publication number CN112623918B discloses an IPFS-based escalator intelligent decision-making method and system, which uses an environmental perception device through a monitoring terminal to obtain the operating data of the escalator, stores the operating data uploaded by the monitoring terminal through the IPFS interstellar file subsystem according to the content-addressable storage model, and regularly uploads the stored operating data to the intelligent decision-making cloud platform through the Internet; uses the information sub-library of the application library to store the monitoring data of the escalator to be monitored uploaded regularly by the IPFS interstellar file subsystem; uses the fault sub-library of the application library to record the cause of the fault of the escalator to be monitored, and extracts the corresponding monitoring data from the information sub-library to form a sample, so as to judge the operating status of the escalator; the decision sub-library of the application library uses the fault type recorded in the fault sub-library to formulate a corresponding fault repair decision, thereby realizing intelligent decision-making of the escalator.

[0004] The existing technology can only repair the escalator after monitoring the escalator for failure, and it cannot provide a reasonable rehabilitation plan. Therefore, we propose an escalator health rehabilitation method based on a hierarchical evaluation model. Summary of the invention
