Abstract
The utility model provides an electric contact temperature on-line monitoring device which includes a temperature detection module and a central processor. An output signal of the temperature detection module is input into the central processor via a communication module. The central processor receives the signal from the communication module, calculates the signal, and then outputs the calculated signal to a display module for display. The input terminal of the central processor is connected with a button circuit. For the electric contact temperature on-line monitoring device, the central processor transmits the recorded information which needs to be displayed to the display module for display according to a received button signal which is input by the button circuit, so a worker can understand the detection records of a detected contact.
