Abstract:On the basis of existing ways of realizing remote calibration and traceability of measuring instruments, a remote calibration method of electrical parameters based on modern communication technology is proposed. The calibration method combines the remote calibration method with non-physical standards as the transmission object and the standard source method of DC voltage source calibration, which places the standards in the laboratory rather than transmitting them to the field, solving the problems of long calibration period and difficult to measure additional errors of the traditional electrical parameter calibration method. Based on the principle of time-frequency calibration by the satellite co-vision method, the standard voltage source and the calibrated electrical parameters are converted into reliable digital quantities for the remote transmission of the electrical parameters, and the transmission and traceability chain of the electrical parameters is established; the reference voltage remote calibration module of the AD conversion module is designed, and a model of the remote self-calibration of the AD conversion module is established, and the remote calibration algorithm of the electrical parameters based on the satellite co-vision is investigated, and the remote self-calibration algorithm of the A/D conversion is also investigated. The remote self-calibration algorithm of analog-to-digital conversion is studied, and the conversion results of high-precision electric parameter acquisition module are corrected. After data analysis, its accuracy is 0.1 level.
