基于uClinux的列车卧铺管理系统

针对列车上列车长收集卧铺信息存在的困难，本文首次提出了基于uClinux的列车卧铺管理系统。它由基于ARM＋u-Clinux的具有网络通信功能的手持式卧铺车厢管理终端和具有数据库的上位机组成。管理终端通过以太网与位于主控室的上位机通信，从而完成列车长与各节卧铺车厢乘务员的信息交流。管理终端结合了ARM微处理器强大的硬件性能，uClinux操作系统稳定完备的系统管理能力和基于MiniGUI的友好的人机界面等特性，使之具备了便捷，小巧，简单易用的优点。列车卧铺管理系统是列车卧铺信息管理的一套数字化解决方案，是嵌入式系统在列车信息化管理中的一个实际应用。

The berth of train management system based on uClinux

According to the difficulty that conductor collected the information of berth on the train, the paper introduced a new berth of train management system which based on uClinux. It has two parts. One is the embedded handhold terminal based on ARM and uClinux which have network communicate function. The other is upper computer with database which can manger the information of berth and communicate with the embedded handhold terminal through the Ethernet. The conductor and the trainman can exchange the berth information and the message from the network communication between the upper computer and the embedded handhold terminal. Because the embedded handhold terminal integrated the strong hardware quality of ARM, the excellent and stable management of uClinux and friendly GUI based MiniGui, it had a lot of advantages such as portable, small and easy to using. The berth of train management system is not only a digital solution of berth information management, but also a practical application of embedded system in the information management process of railway network.
