| Abstract: | The infrared substance moisture measurement instrument is a measurement technique,which is widely used in industry and agriculture production to realize online moisture measurement of the substances at present.Because the output signal of sensor is weak,it must overcome the effect of measurement of noise in the measurement system to improve the accuracy of moisture measurement.It can overcome the noise effect of measurement system and improve the accuracy of measurement efficacy.The result of experiments indicates that it can overcome the noise effect of measurement system greatly and improve the accuracy of the key problems in measurement effective to apply the modern filter technique Boxcar digital filter into infrared substance moisture measurement.It also describes the principle and method of Boxcar digital filtering algorithm realized by computer. |
