Icing environment wind speed and wind direction measuring device and method based on heat balance

The invention discloses an icing environment wind speed and wind direction measuring device and method based on heat balance. The device comprises a shell, a cavity is formed in the shell, and a heating device is arranged on the outer side of the shell; the heating device further comprises a main control system, the heating device is connected with the main control system, and the heating device is further connected with a temperature control circuit and a temperature detection circuit. The method comprises the following steps that an environment temperature sensor detects the current environment temperature and feeds back the current environment temperature to a main control system; when the environment temperature is lower than the set device surface constant temperature, the main control system controls the heating device to start heating; the main control system measures the constant-temperature power of the local shell of each heating device, and calculates the current average wind speed by comparing the
