Abstract:This paper first analyzes the test requirements of the tire pressure of the machine, then briefly introduces the traditional tire pressure test technology, and at the same time proposes a suitable tire pressure test technology based on wireless transmission. In this paper, the key technologies such as system function design, tire pressure collection principle, data transceiver wireless communication technology and power supply design are deeply discussed and studied, which provides technical methods and support for the collection and real-time monitoring of tire pressure. Finally, through laboratory comparison and verification, the test results meet the test requirements of flight test, and can be applied in the flight test to meet the needs of aircraft performance test flight and safety monitoring.
