Through the analysis of the phenomenon of large operation equipment heat failure, it is put forward in the paper that use the semiconductor temperature sensor converted the signal of temperature difference into weak voltage combined with controlled boost DC-DC converter circuit to provide power to ultra-low-power temperature measurement circuit controlled by single chip microcomputer and output the temperature measurement information in the form of infrared modulation signal. Focused on solving the thermal power modules in semiconductor output voltage instability, small pressure differential, DC-DC converters start of the ultra-low-voltage problems, combined with the practical application of the environment at the scene of an independent power supply and temperature measurement devices, as well as the composition of the work carried out Further explore.
