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.
