Abstract

The invention belongs to the field of rail transit, and provides a turnout switch machine contact frosting and dewing early warning method and system and a storage medium, and the method comprises the steps: obtaining a current temperature value of an environment where a turnout switch machine contact is located; according to the historical environment data, determining a dew point temperature threshold within a preset time range before the current moment; the current temperature value is compared with the dew point temperature threshold value; and determining and generating frosting and dewing early warning information based on the comparison result. Based on an algorithm of a sliding time window, through analysis of the temperature and the relative humidity in the switch machine, judgment and early warning of dew formation and frosting of the contact of the switch machine are achieved, the method further comprises the steps of continuously and dynamically updating a dew point temperature threshold value, and through the algorithm of the sliding time window, self-adaption to season and weather changes is achieved. The method has strong robustness for dealing with short-term emergencies, provides support for the maintenance of the turnout switch machine, and reduces the operation and maintenance cost of the on-site switch machine.
