基于Flash的列车电子地图存储方法
Method for Storing Digital Maps of Trains Based on Flash
摘要
Abstract
To adapt to the natural conditions of railways in western China,the train control system needs to meet the requirements of fewer trackside devices,reduced maintenance workload,and high transport efficiency.The mature application of digital maps in train control systems can effectively reduce the deployment quantity of trackside devices such as trackside balises that assist in train positioning.In view of the characteristics of digital map files and Flash storage mechanisms,this paper proposes a storage management algorithm for digital map files in onboard equipment.The proposed algorithm is not limited by the size of digital map files,enabling dynamic allocation of storage space.It recovers available storage space in real time based on map file updates,achieving efficient reading and updating of digital map files by onboard equipment in typical scenarios of Chinese Train Control System-New(CTCS-N).关键词
