The invention discloses a shield tunnel construction whole process cooperative monitoring method and system based on digital twinning, and the method comprises the steps: firstly determining a monitoring element system, collecting multiple types of data, accessing the resources of each participant, carrying out the standardization processing to form a shared data resource pool, and constructing a total element digital twinning model based on the resource pool, synchronous mapping of a physical construction scene and a digital model is realized through dynamic updating of a linkage mechanism of data and the model; then, a multi-participant cooperative monitoring platform is built, space-time dimension coupling correlation analysis is carried out on multi-source data in the model by means of a platform fusion analysis module, dynamic causal correlation rules of structural response, environmental change and construction behaviors are extracted, and risk pre-judgment and early warning are completed in combination with a safety judgment standard and a real-time working condition correction threshold value; and finally, early warning information and disposal suggestions are pushed, a model simulation effect is utilized, feedback data are tracked to form closed-loop management, and risk controllability is ensured. And the intelligent level of construction safety management and control is improved.

This invention relates to a manganese-cerium composite oxide catalyst, its preparation method, and its application in the catalytic oxidation of tetrahydrofuran to γ-butyrolactone, belonging to the field of hydrogen energy utilization and chemical hydrogen storage technology. Using a manganese-cerium composite oxide catalyst (manganese-based oxide) as the catalyst, tetrahydrofuran is selectively oxidized to γ-butyrolactone in the presence of an oxidant. It can be used for the resource-based conversion of byproduct tetrahydrofuran in a γ-butyrolactone / 1,4-butanediol liquid organic hydrogen storage cycle system, achieving closed-loop recycling of materials. Compared with existing technologies, the manganese-based catalytic system of this invention has advantages such as wide availability of raw materials, low cost, mild reaction conditions, and high product selectivity. It can effectively reduce the adverse effects of tetrahydrofuran accumulation on the system's economy during multiple hydrogen storage cycles, and has good prospects for industrial application.

The invention relates to the technical field of identity recognition, and discloses a student apartment access early warning system and method based on dynamic permissions, and the system comprises a permission presetting module, a state adaptation module, a strategy reconstruction module, a rule matching module, an access judgment module and an early warning generation module. Obtaining a static permission configuration table; performing parameter adjustment on the student management database and the static permission configuration table to obtain a state adaptation parameter set; performing dynamic rule reconstruction on the static permission configuration table to obtain a real-time permission strategy; performing permission rule matching on the current access request to obtain a permission matching analysis result; performing admission compliance state confirmation on the permission matching analysis result and the current access request to obtain an admission judgment result; performing structured integration on the access requests with illegal admission judgment results to obtain a standardized early warning report; according to the invention, the efficiency of student apartment access early warning based on dynamic authority can be improved.

This application discloses a temporary power consumption management system, method, equipment, and storage medium, relating to the field of power consumption management technology. The system includes: a business application module, an application approval module, a time limit monitoring module, and a reminder push module. The business application module is used to trigger the temporary power consumption management process; the application approval module is used to track the process approval; the time limit monitoring module is used to monitor the power consumption period and determine the temporary power consumption status (including not yet due, nearing the end of the period, and expired); the reminder push module pushes inspection prompts to the inspection terminal when the status is nearing the end of the period or expired; the inspection terminal receives the prompts and reports the inspection results. Through closed-loop management of online processes, automatic monitoring, early warning pushes, and inspection feedback, the system fundamentally solves the defects of manual management models, such as the risk of overdue power consumption due to omissions in manual verification, and is conducive to meeting the institutionalized and refined management needs of power plant safety production.
