摘　　要：铁路信号轨旁安全平台的通信板卡出现故障时,为了能安全地在线更换,研究一种热插拔技术。采用逻辑板与通信板2个模块的通信交互来实现通信板的热插拔。该热拔插技术可提高轨旁安全平台在现场的可用性和可维护性,极大地提高通信板卡使用的灵活性和扩展性。This paper introduces a hot-swap technology for safe on-line replacement of the communication board of the railway signal rail-side safety platform when it is out of order.The communication interchange between logic board and communication board is adopted,and the interaction process between communication board and logic board when communication board is connected to the system is completely described.The hot plug technology can improve the availability and maintainability of the rail-side security platform in the field,and greatly improve the flexibility and expansibility of the use of communication boards.
