摘要（英）：

The present invention discloses a free electron thermal motion-based thermal signal detection system. The system comprises a frequency selection and amplification unit, a detection unit and a control unit; the frequency selection and amplification unit is used for performing frequency selection on thermal signal spectra generated by free electron thermal motion in a conductive network to obtain frequency selection signals and performing amplification processing on the frequency selection signals; the detection unit is used for performing detection on the amplified frequency selection signals and outputting a temperature value corresponding to the frequency selection signals; and the control unit is used for identifying the temperature value so as to obtain the current temperature state of the conductive network. According to the free electron thermal motion-based thermal signal detection system of the invention, the temperature detection and arc detection of the conductive network are realized based on the spectral characteristics of the free electron thermal motion in conductors, and therefore, problems such as noise superposition interference can be avoided. The system has the advantages of high detection precision, low detection cost and high universality.
