The invention relates to the technical field of temperature measurement, in particular to a signal enhancement temperature control system. The signal enhancement temperature control system comprises asupport, wherein a heating plate is fixedly connected to the support; the bottom surface of the heating plate is provided with an electric heating assembly; the bottom of the support is fixedly connected with a heat conduction sheet; the distance between the heat conduction sheet and the electric heating assembly at the bottom surface of the heating plate is 1-15mm; a temperature measuring and temperature control element is arranged on the heat conduction sheet; the temperature measuring temperature control element is electrically connected with the electric heating assembly; the electric heating assembly comprises a nanometer electric heating film which is plated at the bottom of the heating plate; and the nanometer electric heating film is electrically connected with a first electrode and a second electrode. The device is free of metal pollution and high in heating speed; by virtue of the excellent heat conduction performance of the heat conduction sheet, such as a copper sheet, theheat radiated from the electric heating film and temperature signals are rapidly transmitted to a temperature controller; and when the temperature exceeds a preset range, power down is performed automatically, so that the electric heating element which is high in power density and high in temperature rise speed and low in heat transfer speed of a heating plate base material is well protected, theelectric heating element is ensured to be safely used, and the service life of the electric heating device is prolonged.
