First of all. This paper briefly introduces electric sensor system use HART protocol and other electric hardware parts. On For the purpose of minimal interference data transmission on Electric Sensor System use continuous phase FSK modulation and demodulation techniques,.Secondly, the use of the advantages of small data and kernel function to the higher space nonlinear map on support vector machine regression algorithm , To predict a mathematical nonlinear model to fit the front sensor of the Electric Sensor System, implement the compensation of parameters in software part. By combining software and hardware methods to improve the accuracy of the Electronic Sensor System.Its fit R=99.777 7%,MSE=9.354 13e-05.
