Design of Tire Pressure Online Detection Device for Aircraft Landing Gear Based on NFC

Aiming at the complexity of the natural and electromagnetic environment in which the aircraft is navigating and the limited space for installing the components, an on-line tire pressure detection device for aircraft landing gear in the passive mode of NFC is designed and implemented based on near-field communication NFC technology and tire pressure sensor detection technology. The circuit such as induction power supply is optimized and the temperature compensation calibration method of sensor is adopted to solve the problem of temperature influence in tire pressure detection. The test results show that the device has good on-demand performance and meets the on-line, high efficiency and accurate detection requirements of aircraft landing gear tire pressure.
