英文摘要The utility model relates to a system for measuring rotating speed of an aviation gasoline engine which takes an igniting generator of an engine as a signal source and comprises a burr filtering unit, a current amplitude limiting unit, a signal isolation unit and a signal inversion unit, wherein an input end of the burr filtering unit is connected with the igniting generator of the engine, an output end of the burr filtering unit is connected with an input end of the current amplitude limiting unit, an output end of the burr filtering unit is connected with an input end of the signal isolation unit, an output end of the signal isolation unit is connected with an input end of the signal inversion unit, and an output end of the signal inversion unit is connected with a rotating speed controller of the engine. With no sensitive device arranged on a rotating part of the engine, ignition pulses of the igniting generator of the engine are used to calculate the rotating speed of the generator. Speed measuring is not influenced by illumination, strong magnetic fields or strong electric fields. Principle is simple and reliable.
