Abstract: As the key equipment of signal system, the communication stability between computer-based interlocking(CBI) and CTC interface is an important guarantee for traffic safety and transportation efficiency improvement. When the communication between CTC and CBI system is interrupted, the field operation will be greatly affected. This paper analyzes the fault of a station caused by the abnormal communication between the CBI system and CTC, which leads to the loss of the interface of the station and yard of the vehicle terminal, and puts forward the corresponding solutions. The field implementation results are good. The relevant solutions improve the stability of the communication between the interlocking system and CTC, and ensure the safe operation of the field equipment. At the same time, it can also provide reference for other stations to deal with similar faults.

Key words: CBI, CTC, communication failure, case analysis
