The invention relates to a signal generation system and method, and the system comprises an acquisition module, a processing module, a phase shift setting module, and a signal adjustment module. The acquisition module is used for acquiring power grid phase reference information and transmitting the power grid phase reference information to the processing module; the phase shift setting module is used for receiving set phase shift angle information and transmitting the phase shift angle information to the processing module; the processing module is used for generating a delay signal according to the power grid phase reference information and the phase shift angle information, and inputting the delay signal into the signal adjusting module; and the signal adjustment module is used for processing the delay signal according to a preset interference signal generation requirement to generate an analog signal. Phase adjustment based on the power grid voltage is achieved, the accuracy and normalization of interference signals are improved, and therefore the efficiency of anti-interference testing is improved.
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...
