摘　　要：针对高速铁路沿线自然环境、地质灾害、基础设施等监控系统接口不一致的现象,设计了一种子系统和平台间的交互响应机制,提供了一套异构分布式监控系统的接口集成解决方案。该接口设计以UDP通信协议为基础,植入TCP协议中的超时重传、握手连接等可靠性传输策略,构建初始化和自检、数据采集及传输、阈值同步等事件触发交互过程,统筹规划UDP报文的编码和数据包格式,从而实现子系统间与平台之间统一、实时、可靠、有效的接口功能,为智慧铁路监测系统的规划发展提供参考价值。A mechanism of interactive response between subsystems and platform is designed for the situation that the monitoring system interfaces with each other are inconsistent, such as natural environment, geological disaster and infrastructure along high speed railway, an integrated solution to heterogeneous distributed monitoring systems is provided. The solution is based on the UDP communication protocol, embedded some reliable transmission methods include timeout retransmission, handshake connection in the TCP protocol. Interactive process including initialization and self- inspection, data collection and transmission, threshold synchronization are constructed. And encodings and packets in UDP message are built to realize the unified, real - time, reliable and effective interface function , to provide reference value for the planning and development of intelligent railway monitoring systems.
