High-reliability airborne tire pressure monitoring method

The invention provides a high-reliability airborne tire pressure monitoring method which comprises the following steps: dynamically adjusting the working state of a sensor node, so that the sensor node is switched among an activated state, a pre-dormant state and a dormant state; when the sensor node is in an activated state or a pre-dormant state, the sampling frequency of the sensor node is adjusted based on a sampling frequency dynamic adjustment algorithm, and tire temperature data and tire pressure data of a tire associated with the sensor node are collected; and the sensor nodes and the gateway nodes output tire temperature data and tire pressure data by adopting an exponential retransmission control strategy according to the received data requests. According to the airborne tire pressure monitoring method designed by the invention, the data acquisition range can be expanded, the data acquisition frequency and sending frequency can be adaptively adjusted, multi-channel collection and summarization of da
