摘要
在阐述高速铁路灾害监测系统结构和功能的基础上,分析系统接口存在接口数据内容、格式和传输方式不统一等问题,提出高速铁路灾害监测系统接口方案,即铁路局中心系统与现场监测设备之间通过应用/通信服务器实现接口数据交换;规定接口数据内容包含指令信息、灾害监测数据和设备状态监测数据,并根据数据类型设定不同的重发间隔;定义接口数据格式;建议接口数据采用OPC异步方式进行传输。
Based on expounding structure and function of high-speed railway disaster monitoring system, this paper analyzes problems related to data, format and transmission mode of system interface, and puts forward the interface program of high-speed railway disaster monitoring system, which adopts the architecture by which data between railway administration central system and on-site monitoring equipment are exchanged via application or communication server; stipulates that data consist of operational orders, disaster monitoring data and equipment status, and sets up different retransmission interval and according to data type; defines data format; and suggests that the interface data should be transmitted using OPC asynchronous mode.
