摘要： An object is to improve the accuracy of prediction of deterioration of railroad ground equipment. Provided is a maintenance assistance system for railroad ground equipment, comprising: an environmental-information storage part storing environmental information containing information on weather observed at a plurality of geographical points and on geographical conditions at the geographical points; and an environmental-load estimation part holding a relational formula indicating the relationship between aged deterioration of railroad ground equipment and the environmental information, and configured to, upon specification of railroad ground equipment for which to execute deterioration prediction, acquire the environmental information which is recorded at a point near the installed position of the railroad ground equipment, during the target period of the deterioration prediction, and predict the degree of aged deterioration of the railroad ground equipment by using the acquired environmental information and the relational formula.

摘要： A degradation estimation system includes a processing unit simulating an operation mode of equipment on a corresponding railroad section at each set-up timing based on corresponding railroad section timetable information, and processing respective simulation results, and an estimation unit aggregating respective processing results of the processing unit. The processing unit simulates a travel transition of each training existing in the corresponding railroad section timetable information as a dynamic of each train based on corresponding railroad section timetable information and a running curve, simulates a state change of each track circuit based on the simulation result and railroad track information, and simulates an operational change of the equipment on each track circuit. The estimation unit aggregates the simulation result of the processing unit indicating the operational change of the equipment disposed on each track circuit, and estimates the degradation of the equipment from the aggregation result.
