Abstract

The invention provides a multi-dimensional cross calibration method in the test and measurement. The method comprises the following steps of determining a measured physical quantity and a real directly-measured parameter; determining all factors influencing the measured physical quantity; determining an intersection of all the factors and a measuring point of each factor containing the measured physical quantity; first measuring a direct parameter value at the intersection, and then measuring a direct parameter value of each measuring point of each factor and a value at the intersection of other factors in measurement; determining the relation between the measured physical quantity and the direct parameter as well as between the direct parameters; normalizing error values of all the factors on the intersection; calculating a value of the measured physical quantity, and completing the calibration and measurement. The method is not subjected to the limit of the dimensions, the relation between the direct parameter and each factor can be conveniently approximated through a polyline method, and the method is easily realized on the engineering; by adopting the normalization concept, only the points on the intersection are measured, so that the measurement data are greatly reduced; by adopting the polyline method, the measurement precision is high.

Description

technical field [0001] The invention belongs to the field of test and measurement, and in particular relates to the calibration used for the measured physical quantity affected by multiple factors, in particular to the multi-dimensional cross calibration method in the test and measurement. Background technique [0002] In the field of test and measurement, the measured physical quantity is often affected by single or multiple factors, and has a nonlinear relationship with some factors. At present, the broken line segment method or table look-up method is often used for calibration, but when there are more factors affecting the measurement and higher accuracy requirements, the more difficult it is to realize the technology, the larger the measurement data, and it is not easy to realize it in engineering. In order to illustrate the traditional calibration method and the calibration method invented in this paper, the following measurement cases are listed: [0003] (1) Measure...
