Abstract
According to the measuring principle of aircraft engine rotate speed sensor
an smart rotate speed sensor based on distributed control is proposed and designed.Software process
signal adjusting circuit and DSP peripheral port circuit is designed
and program is compiled.The experiment results prove that the smart sensor not only has measuring error as precise as 0.02%
but also high integration and high processing speed.It is suitable to the distributed control of aircraft engine.
