铁路信号系统是保证运输安全的基础设施,是实现铁路统一指挥调度,保证列车运行安全,提高运输效率和质量的关键,是铁路信息化的重要技术领域。铁路信号系统会随着铁路运输的发展而发展,信号监控系统的未来发展将克服传统信号监控系统的不足,指出了新型通信信号监控将替代传统信号监控的必然。 Railway signaling system is to ensure the safety of transport infrastructure is to achieve a unified command and dispatch of railways to ensure the safety of train operation, improve transport efficiency and quality of the key, is an important railway information technology. The railway signal system will develop with the development of railway transportation. The future development of signal monitoring system will overcome the shortcomings of the traditional signal monitoring system. It is pointed out that the monitoring of new communication signals will replace the traditional signal monitoring.
