The problem of non-contact infrared temperature measurement is analyzed. A simple and accurate measuring system is designed, by gathering the spectrum signals into MCU, analyzing infrared emitting ability of the object repeated-ly, calculating spectrum distribution of the blackbody and the accurate temperature of the object with the Weien displace-ment theorem. The system has the advantages oi high signal-to-noise, good resolution, preciseness and rapidness of meas-urement, and friendly display interface, etc, in the measuring scope of temperatures of the object from 0 ℃ to 100 ℃ in the environmental temperatures from 0 ℃ to 60 ℃.
