A locomotive toilet antifreeze emptying intelligent control method and system

The present application relates to the technical field of antifreeze for locomotive sanitary facilities, and specifically to a locomotive toilet antifreeze emptying intelligent control method and system, the method comprising: using a dynamic weighted fusion algorithm to dynamically allocate weights for multi-source locomotive toilet-related data, quantifying the dynamic risk index of multi-source locomotive toilet-related data within the current analysis period; combining the long-term risk trends and short-term risk mutations of all dynamic risk indices calculated for all collected analysis periods, and fusing the two to construct a long-term and short-term dual-modal icing risk index; and using the dual-modal icing risk index to set a multi-level threshold antifreeze mechanism strategy. The present application aims to enable locomotive toilets to dynamically adapt to extreme cold environments, reduce energy consumption, and avoid misjudgments and failures caused by static weight allocation and single indicator evaluation in traditional systems through dynamic long-term and short-term risk analysis and graded antifreeze processing of multi-source locomotive toilet-related data.
