Description

technical field [0001] The invention relates to an engine speed detection system, in particular to an engine speed simulator based on a power supply controller, which belongs to the field of engine speed detection. Background technique [0002] As one of the most commonly used electronically controlled measuring instruments in electronically controlled measuring systems, signal generators are basic instruments commonly used in industrial control, teaching, and scientific research. Although various signal generators have gradually appeared on the market, they still cannot get rid of the shortcomings of large volume, many operation buttons, and high price, which brings inconvenience to the power system engineering personnel to go out to debug and overhaul the electronic control equipment. Considering many factors, it is very necessary to develop a multifunctional engine speed simulator with simple structure, easy to carry and use. It can simulate and output the speed (frequen...
