Abstract

The invention discloses a protection method for preventing a data network storm of a railway signal TDCS / CTC system. According to the method, the complex networking of the railway signal TDS / CTC system can be realized; under the conditions of wrong software logic connection, abnormal data configuration and the like, a data loopback network storm is prevented through software logic protection, so that the overall data transmission availability of the TDCS / CTC system is not influenced, an alarm can be given to the outside in time, and a maintainer is notified to carry out analysis and processing.

Description

technical field [0001] The invention relates to the field of railway science and technology, in particular to a protection method for a railway signal TDCS / CTC system to prevent data network storms. Background technique [0002] TDCS / CTC system is currently widely used in all railway bureau group companies, and is also used in various local railways. The TDCS system mainly realizes the supervision of train operation, and assists the traffic dispatchers to dispatch and command the trains along the entire line; the CTC system can realize functions such as centralized control of train operation, safety card control, and automatic routing; TDCS / CTC system is improving railway traffic It plays a very important role in transportation efficiency and ensuring operation safety. [0003] In each railway bureau group company, with more than ten years of gradual construction and operation, the network structure and logical structure of the TDCS / CTC system have become increasingly compl...
