高铁中继站信号的异常检测及实时报警技术

Detection of signal anomaly and real-time alarm technology of high-speed relay station

传统报警技术自动控制水平低,无法准确判断安全监控器异常行为,为此,提出高铁中继站信号安全监控器异常实时报警技术研究。依据Syslog协议采集高铁中继站信号,在运用门限法检测安全监控器是否存在异常行为。综合上述两个步骤,使用Visual Studio开发工具实现异常实时报警技术。由此,完成高铁中继站信号安全监控器异常实时报警技术的研究。在实验中,选择100组样品集,分为两组,50组为卡死状态,50组为突变型异常状态,应用这100组特征参数,分别测试两个技术的误差收敛度,实验结果表明,所建技术误差收敛度为0.01,能够准确识别安全监控器异常行为,及时报警。

Traditional alarm technology has a low level of automatic control and can not accurately judge the abnormal behavior of safety monitor.Therefore,the research of abnormal real-time alarm technology for signal safety monitor of high-speed railway relay station is put forward.According to Syslog protocol,the signal of high-speed railway relay station is collected,and the threshold method is used to detect whether the safety monitor has abnormal behavior.Combining the above two steps,the abnormal real-time alarm technology is realized by using visual studio development tool.Thus,the research of abnormal real-time alarm technology of signal safety monitor in high-speed railway relay station is completed.In the experiment,100 sets of samples are selected and divided into two groups.Fifty groups are stuck and fifty groups are prominent abnormal states.The error convergence of the two techniques is tested by using these 100 sets of characteristic parameters.The experimental results show that the error convergence of the two techniques is 0.01,which can accurately identify the abnormal behavior of the safety monitor and report it in time.
