浅谈TMIS数字电路的维护与测试

Brief Discussion about Maintenance and Test over TMIS Digital Circuit

TMJS 网络是铁路信息化的基础,为保证铁路运输安全、正点、高效发挥着不可替代的作用。本文就日常维护中如何尽快判断 TMIS 网络故障、通道传输质量以及2M 数字电路的误码测试方法等方面进行了较为详尽的阐述。

Being the foundation of railway informatization,TMIS network plays an irreplaceable role in ensuring the safety,punctuality and high efficiency of traffic operation.The paper expatiates how to judge as quickly as possible in routine maintenance the failure of TMIS network,transmission quality of the channel and the methods of testing error code of 2M digital circuits.
