LED信号机的检测报警技术研究

Research on the technique of testing and alarming LED signal machines

铁路及轨道交通的运行离不开信号机,而正确的信号是安全运行的基本保障。随着科学技术的发展,信号机及其检测技术也在不断发展。本文介绍了传统的信号机和新型LED信号机的工作原理,并介绍了对新型LED信号机的检测原理及检测电路,同时简要介绍了检测报警系统的构成。经过实验证明,该系统能满足现场检测的要求。

The running of railway and orbit traffic is not off the signal machines, and the correct signal is the basic ensurement for safe running. The signal machine and its testing technique are developed continuously along with the science and technology. The work principle of traditional signal machines and new type LED signal machines are presented in this paper. The test principium and its test circuits of new type LED signal machines are described. At the same time, the configuration of test system is introduced. This system can do on-line testing.
