在新的发展时期,列车的运行速度不断提高,高速铁路的总里程不断增加,对于铁路部门的运输安全和应急通信保障能力提出了更高的要求。一旦列车在行驶过程中遇到突发事故,应急通信系统必须能够迅速将现场信息传递到指挥中心,做好及时的应对和处理。本文对高速铁路应急通信系统的结构和接入技术进行了分析和探讨。
In the new period of development, the running speed of trains is continuously increasing, and the total mileage of high-speed railways is constantly increasing, putting forward higher requirements on the transportation safety and emergency communications support capabilities of the railway departments. Once the train encounters an accident in the course of driving, the emergency communication system must be able to quickly transmit the site information to the command center, so that the emergency response and handling can be carried out promptly. This paper analyzes and discusses the structure and access technology of high-speed railway emergency communication system.
