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 data can be realized, and the application of airborne scenes and maintenance scenes can be met.
本发明提供了一种高可靠性的机载胎压监控方法,包括动态调整传感器节点的工作状态,使传感器节点在激活状态、预休眠状态、休眠状态三个状态之间切换;传感器节点处于激活状态或预休眠状态时,基于采样频率动态调节算法调整传感器节点的采样频率,并采集与该传感器节点相关联的轮胎的胎温数据及胎压数据;传感器节点以及网关节点依据其接收的数据请求,采用指数级重传控制策略输出胎温数据及胎压数据。本发明设计的机载胎压监控方法能实现扩大数据采集范围,自适应调整数据采集频率及发送频率,可以实现数据的多渠道收集汇总,满足机载场景、维护场景的应用。
