Interface equipment and method for performing data exchange

Abstract

The invention discloses interface equipment and a method for performing data exchange. The interface equipment is configured to provide a function for a radio block center RBC system for performing data exchange with a dispatching center CTC system, and comprises an RBC interface unit, a data processing unit and a CTC interface unit, wherein the RBC interface unit is used for receiving uplink datafrom one or more RBC hosts in an RBC system, performing correctness verification on the uplink data, and transmitting the uplink data to the data processing unit after determining that the uplink data passes the correctness verification; the data processing unit is used for analyzing the uplink data so as to determine a processing type, determining a processing strategy for the uplink data basedon the processing type, processing the uplink data according to the processing strategy, and transmitting the processed uplink data to the CTC interface unit; and the CTC interface unit is used for performing format conversion on the processed uplink data based on a data format of a CTC system, and transmitting the uplink data after format conversion to the CTC system.

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). component. 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...

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
