1. A protection method for radio frequency operation abnormality, comprising steps of:
detecting preset kinds of detection data of a radio frequency operation in real time when detecting that a radio frequency host continuously outputs radio frequency energy;
determining whether detected preset kinds of detection data meets a preset abnormal state; and
controlling a radio frequency generating apparatus to stop outputting radio frequency energy and controlling an emergency stop apparatus to cut off a radio frequency energy output path of the radio frequency host when the preset abnormal state is met,
wherein the step of detecting preset kinds of detection data of a radio frequency operation in real time comprises:
detecting an impedance value and/or a temperature value of the operated object of a radio frequency operation in real time,
wherein the step of determining whether detected preset kinds of detection data meets a preset abnormal state comprises a step of:
determining whether the impedance value of the operated object is higher than a first preset impedance threshold, and whether a duration time of being higher than the first preset impedance threshold is greater than a preset duration; and/or whether the temperature value of the operated object is higher than a first preset temperature threshold, and whether a duration time of being higher than the first preset temperature threshold is greater than the preset duration.
