Research of the drive mode and reliability for rail vehicle LED drive system

The drive system is an important part of the LED lighting control system of rail vehicle compartment. The stable and efficient operation of drive system has important significance for the whole control system. The driving mode of the drive system directly affects the stability of the LED lighting control system. In order to improve the reliability of the drive system of rail vehicle compartment LED lighting control system, different driving modes are researched by using reliability block diagram analysis. In this method, the logical relation of each component of the drive system is expressed by adopting block diagram. The reliability model of the drive system is established according to the logical relation. The reliability of each drive system is obtained, and the optimal operation scheme of the drive system is obtained. The analysis process demonstrates that the reliability block diagram analysis has the advantages of both intuitive and practical, and the reliability block diagram method is mastered easily. Meanwhile, the driving mode provides the theoretical basis for the determination of the optimal operation scheme of drive system and strong guarantee for the reliability operation of the drive system.
