The invention can be applied in a hostile environment on the airplane and is easy to meet the requirement of electromagnetic compatibility on the airplane.

Description

technical field [0001] The invention relates to a communication device, in particular to a rotary transformer coupling communication device in an aircraft tire pressure real-time monitoring system. Background technique [0002] Aircraft tire pressure real-time monitoring system is a kind of monitoring the air pressure inside the tire, providing the actual pressure of the tire to the crew or maintenance personnel through the data bus and display, and can give an alarm to the abnormal tire pressure, and can adjust the tire pressure according to the driver's instruction. It is a device for regulating the pressure of aircraft tires, which is a new technology to ensure the safety of aircraft. In daily maintenance, the system can also eliminate the manual measurement of tire pressure on the ground, reducing the workload of tire maintenance. [0003] In the aircraft tire pressure real-time monitoring system, the in-wheel monitoring module is located on the wheel and rotates with t...
