摘　　要：探讨铁路系统中无线传感器的低功耗电源管理策略,并提出一种创新的改进策略。先介绍了铁路传感器系统的架构和相关的能源管理电路设计,然后分析了系统的状态转换过程,包括状态切换时间点和功耗问题。基于这些分析,提出一种自适应功耗模块激活策略,该策略根据传感器传输数据的频率和重要性来动态调整功耗模块的激活频率。此外,还研究了基于状态切换的功率优化方法,以最大限度地减小功率消耗。This study explores low-power power management strategies for wireless sensors in railway systems and proposes an innovative improvement strategy.Firstly,this article introduces the architecture of the railway sensor system and the related energy management circuit design.Then,this article analyzes the state transition process of the system,including the time point of state transition and power consumption issues.Based on these analyses,an adaptive power module activation strategy is proposed,which dynamically adjusts the activation frequency of power modules based on the frequency and importance of sensor transmission data.In addition,this paper also studies power optimization methods based on state switching to minimize power consumption.
