The invention discloses a railway signal track circuit code sending and annunciator display dual verification method and system, track circuit code sending and annunciator lighting are independent operation subsystems of a current signal system, and code sending errors or annunciator display errors are major potential safety hazards. On the premise that normal work of the two subsystems is not affected, first verification of railway signal track circuit information codes and signal machine display is established, then second verification of a railway signal track circuit key relay and a signal machine circuit key relay is carried out, dual verification is carried out to compare the consistency between the two systems, and the consistency of the two systems is improved. Related information is collected in real time and compared and analyzed, corresponding relation errors are found in time through double comparison, potential safety hazards are alarmed in advance, the method can serve as an important means for fault detection, the operation and maintenance efficiency can be improved, and safe operation can be guaranteed.

    本发明公开了一种铁路信号轨道电路发码和信号机显示双重校验方法及系统,轨道电路发码和信号机点灯是目前信号系统独立运行的子系统,而发码错误或者信号机显示错误都是重大安全隐患,本发明在不影响两个子系统正常工作的前提下,建立铁路信号轨道电路信息码和信号机显示的第一重校验,再进行铁路信号轨道电路关键继电器和信号机电路关键继电器第二重校验,进行双重校验对比两个系统间的一致性,实时采集相关信息并进行对比分析,通过双重比对,进而及时发现对应关系错误、对安全隐患进行提前报警,本发明可作为故障检测的重要手段,可以提高运维效率和保障安全运行。
