Asia’s largest railway marshalling yard in optical communication transmission system protection ring constructed successfully

Assuming the Asia’s largest railway marshalling yard of Henan North Station in Zhengzhou communication tasks in TMIS, TDCS, 5T, reduce the number of optical communication transmission system can be self-healing ring construction method successfully, thus putting an end to Zhengzhou North Station area optical communication network has over the years can not effectively protect the history.

Due to the special geographical environment and objective factors, Zhengzhou North Station area of optical communication network development into the system, has not formed the self-healing optical communication transmission channel, once cable interruption, will be because there is no inverted generation conditions to ensure the normal transmission of important railway business information, will undoubtedly threaten railway communication system security and stability. In recent years, with the construction of railway informatization demand continues to expand, Zhengzhou North Station area communication network construction has been crunch time. Henan Zhengzhou Railway Communication Center after many on-the-spot investigation and study, repeatedly revised construction organization measures and programmes in business, but on behalf of the relentless efforts, providing a variety of interface equipment to supply emergency purposes, and actively coordinate the Zhengzhou railway department, increase investment strength, laying a total of 6 kilometers, built Zhengzhou North Station area terminal adjustable floor YIS first to, on, to, issued a four signal box can be self-healing optical network transmission system. The transmission system protection ring will be built, for the railway transportation to provide a more secure, more reliable communication security.
