Abstract

The invention provides a waveform display processing method and system of a measuring instrument. The method comprises the following steps: inputting at least one mathematical expression character string, wherein the mathematical expression character string comprises a measuring item character string, or measuring item character strings and an operator, or the measuring item character strings and a function, or the measuring item character strings, the operator and the function; carrying out reverse Polish notation transformation on the mathematical expression character string, and storing a transformed expression into a data structure, wherein corresponding measuring items are determined in a transformation process of the mathematical expression character string through mapping relationships of the measuring item character strings and the measuring items; traversing the data structure, and carrying out expression operation to obtain data points of a to-be-displayed waveform; and forming, through repeatedly executing the previous step, all data points of the to-be-displayed waveform to acquire and process all measuring data corresponding to all the measuring items. According to the waveform display processing method and system of the measuring instrument, waveforms of more complicated mathematical operation can be displayed, and more measuring demands can be satisfied.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a waveform display processing method and system for a measuring instrument. Background technique [0002] In measuring instruments, in order to reflect the measurement results in real time and conveniently, they usually have their own display screens to display the waveforms, such as oscilloscopes, which can display current, voltage and other waveforms during the measurement process, as well as power analyzers and waveform recorders. Instruments and meters with electrical measurement functions, such as power online monitoring devices, have the function of displaying waveforms. [0003] Existing instruments and meters can usually only display the measurement data after simple operations of addition, subtraction, multiplication, and division, and cannot display the waveforms of complex mathematical operations, resulting in the inability to display measurement results ...
