Interface equipment and method for performing data exchange

Abstract

The invention discloses interface equipment and method for performing data exchange. The interface equipment is used for providing a function for performing data exchange with a wireless blocking center RBC system for a scheduling center CTC system, wherein the interface equipment comprises a CTC interface unit for receiving downlink data from the CTC system, checking the correctness of the downlink data, and sending the downlink data to a data processing unit after determining the passing of the correctness checking; the data processing unit for analyzing the downlink data so as to determinea processing type, determining a processing policy for the downlink data according to the processing type, and determining an identifier of each of one or multiple RBC hosts of a RBC system associatedwith the downlink data according to the processing policy; and a RBC interface unit for determining one or multiple target RBC hosts in the RBC system based on the identifier of each of one or multiple RBC hosts, and sending the downlink data to each target RBC host in one or multiple RBC hosts.

Description

technical field [0001] The present invention relates to the field of data transmission, and more particularly relates to an interface device and method for data exchange. Background technique [0002] The interface between Radio Block Center (RBC, Radio Block Center) and Centralized Traffic Control (CTC, Centralized Traffic Control) RBC-CTC is an important part of signal control in the CTCS-3 train control system of China Train Operation Control System (CTCS, Chinese Train Control System). There is a data exchange function between RBC and CTC. CTC can send text message, emergency stop order to RBC, and provide clock synchronization function to RBC. RBC periodically sends train information to CTC, where train information includes train number, train speed, working mode level, train location, wireless communication status, and driving permit. The RBC is also able to send feedback to the CTC for emergency stop commands and text messages. [0003] At present, most manufacture...

Problems solved by technology

In the case of direct connection of signal systems with different security levels, equipment and networks with low security levels are likely to cause adverse effects and interference on equipment and networks with high security levels;

[0006] 2. In the case of direct connection between CTC and RBC, the logic processing inside the RBC system is usually increased, so it is easy to affect the processing of other core logic of the RBC system

[0007] 3. When one set of CTC is directly connected with multiple sets of RBC, it will increase the complexity of network design and network connection, thus increasing the burden of network design and network connection

[0008] 4. When the logic processing of CTC involves multiple RBCs, it will increase the logic complexity of the CTC system
