Equipment working state monitoring system and method based on Internet of Things

The invention discloses an equipment working state monitoring system based on Internet of Things and a method thereof. The method comprises the following steps of: firstly, acquiring temperature values of monitored equipment at a plurality of preset time points in a preset time period through a temperature sensor, then acquiring power values of the monitored equipment at the plurality of preset time points through a power sensor, and finally acquiring the temperature values of the monitored equipment at the plurality of preset time points. The method comprises the steps of obtaining temperature values of a plurality of preset time points and power values of a plurality of preset time points, performing time sequence correlation analysis on the temperature values of the plurality of preset time points and the power values of the plurality of preset time points to obtain temperature-heat generation correlation characteristics, and finally determining whether the working state of the monitored equipment is abnor
