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...
