Denoising radio frequency spectrum peak value acquisition method based on Internet of things electric power temperature measurement equipment

Abstract

The invention relates to a denoising radio frequency spectrum peak value acquisition method based on Internet of things electric power temperature measurement equipment. The denoising radio frequency spectrum peak value acquisition method based on the Internet-of-things electric power temperature measurement equipment comprises the steps of firstly, measuring and collecting the echo energy values of all frequency points within a label band width range, and re-measuring a frequency point if burr occurs suddenly in the measurement process so as to achieve the aim of eliminating the burr; then eliminating smaller bulges in a frequency spectrum curve line by a smoothing algorithm, and reducing the amplitude of a larger bulge in the curve line; and finally, acquiring all peak values in the curve line accurately by a five-point peak value judgment method. By adopting the method, the influences on the temperature measurement equipment caused by the interference of the same-frequency-band radio frequency equipment, environment noise and measurement errors are effectively avoided, further, the frequency spectrum curve peak can be acquired correctly, and finally temperature can be measured correctly. The real-time monitoring on equipment in running is realized by utilizing an SAW-RFID (surface acoustic wave-radio frequency identification device), so that electric power operation departments can forecast the failure and can solve problems in advance, and a large amount of economical loss and injuries and deaths of people in failure are prevented.
