The utility model discloses a cavity hot-air blower baking temperature monitoring system, which comprises a hot-air blower, a controller and a temperature monitoring unit, the temperature monitoring unit comprises a temperature sensor, and a detection signal of the temperature sensor is sent to the controller after being processed by a double operational amplifier adjusting circuit and a filtering conversion circuit in sequence. The controller is used for controlling the working state of the air heater, the temperature sensor detects the temperature in the cavity in real time, a detection signal of the temperature sensor is sequentially processed through the double-operational-amplifier adjusting circuit and the filtering conversion circuit, and the accuracy of temperature detection is effectively improved. And the controller controls the working state of the hot-air blower to enable the temperature in the cavity to be always within the temperature range set by the system, so that the casting is well ensured
