Abstract

The present application relates to a signal generation system and a signal generation method, wherein the signal generation system includes: an acquisition module, a processing module, a phase shift setting module, and a signal adjustment module; the acquisition module is used to acquire phase reference information of the grid, and The grid phase reference information is transmitted to the processing module; the phase shift setting module is used to receive the set phase shift angle information, and the phase shift angle information is transmitted to the processing module; the processing module is used to information, generate a delayed signal, and input the delayed signal into the signal adjustment module; the signal adjustment module is used to process the delayed signal according to the preset interference signal generation requirements, and generate an analog signal. It realizes the phase adjustment based on the grid voltage, improves the accuracy and standardization of the interference signal, thereby improving the efficiency of the anti-interference test.

Description

technical field [0001] The present application relates to the field of signal processing, in particular to a signal generating system and a signal generating method. Background technique [0002] In the process control system of industrial production, the stability of process signal measurement is related to the quality, efficiency and safety of the production process. At present, the process control system is often tested against power frequency (50Hz) common mode and series mode (also called differential mode) interference based on the interference signal to evaluate the measurement stability of the process signal. Among them, at present, the phase adjustment of the interference signal is often realized by nonlinear devices such as capacitors. The interference signal generated by it is highly distorted and has the problem of "false phase shift", which leads to the accuracy and standardization of the generation of the interference signal. Low, which in turn leads to low ef...
