Abstract
A radio frequency heating system includes a radio frequency heating chamber, a fluorescence temperature measuring transmitter, and a central control unit connected to the fluorescence temperature measuring transmitter. A radio frequency heating container is arranged at the bottom of the radio frequency heating chamber. The radio frequency heating container comprises a fluorescent material with temperature-sensitive fluorescent characteristics, which is excitable by excitation light to produce fluorescence. A light path is provided between the radio frequency heating container and the fluorescence temperature measuring transmitter. The fluorescence temperature measuring transmitter includes a light emitting device for generating excitation light and a driving circuit thereof, a photoelectric converter device for receiving fluorescence, and a signal processing and output circuit for processing output signals of the photoelectric converter device.
