The invention provides a temperature monitoring method of electrical equipment based on a wireless network. The method comprises the steps of: obtaining a product model of a target monitoring component of the electrical equipment and searching for temperature monitoring point information matching the product model of the target monitoring component from an electrical equipment configuration tableof a server; performing temperature collection on the component of the target monitoring component through a temperature collection module, and transmitting collected temperature data to the server; and comparing, by the server, the received temperature data with a preset alarm temperature of a monitoring point in the electrical equipment configuration table to generate a temperature monitoring result of a temperature detection point. By adopting the temperature monitoring method provided by the invention, the temperature monitoring results, continuous temperature jump monitoring results and intermittent temperature jump monitoring results of critical components and non-critical components of the electrical equipment can be analyzed, and meanwhile, the state of the electrical equipment canbe intelligently analyzed; and furthermore, the temperature jump condition of the temperature detection point caused by the own fault of the temperature sensor is eliminated.
