Abstract: A smart speed sensor based on DSP for aeroengines was proposed. The speed signal processing circuit, the driving LED circuit, and the interface circuit between DSP and CAN buses were designed. A new speed measurement method by dynamically dividing frequency of speed signal was proposed. The precision of speed measurement was improved. The experiment indicates that the real-time response of the smart speed sensor has satisfactory performance and the relative error of speed measurement is less than 0.01%. The smart speed sensor is suitable for aeroengine distribution control systems.
