【Abstract】 For the need of aeroengine distributed control system,a smart pressure sensor for aeroengine based on BP neural network was proposed.Firstly a model of BP neural network was built for the sensor.Then the hardware structure used by DS18B20 and ATmega128 was designed.Finally the sensor software was designed.Result of experimentation proves that the smart sensor has sample structure,great linearization and high measuring precision.So it can satisfy the need of aeroengine distributed control system.更多还原
