| Abstract: | According to the principle of aeroengine temperature sensor,aeroengine smart temperature sensor based on DSP and CAN is proposed.Automatic detecting circuit,signal adjusting circuit,DSP and CAN peripheral port circuit and electrical source circuit are designed.The degree of integration about the system is high and the measuring and handling speed is fast.Result of experimentation proves that the smart sensor not only has small measuring error,but also has high integration and high processing speed.So it can be applied in aeroengine full authority digital electronic control(FADEC) system,and it has great important practical value. |
