Abstract

The invention discloses a hot loading method and apparatus for a VOBC (Vehicle On Board Controller) configuration file in a cross-line train. The method comprises the steps of viewing whether a configuration file of a to-be-operated line is downloaded or not when it is determined that a current train needs to be subjected to cross-line operation in an operation process; when the configuration file is not downloaded, in each operation cycle of the VOBC of the current train, downloading the configuration file by steps from a storage unit of the train according to system resources occupied for running a VOBC program; and after the configuration file is downloaded, initializing the configuration file by steps in each operation cycle of the VOBC, thereby finishing hot loading of the configuration file, wherein a memory region occupied for running the VOBC and a memory region occupied for downloading the configuration file are independent of each other. According to the method, configuration data of all lines does not need to be stored in a system memory in which the VOBC is located, so that the expansibility of a system is higher and the VOBC can be subjected to cross-line operation in any number of lines.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and device for thermal loading of VOBC configuration files in cross-line trains. Background technique [0002] In the existing urban rail transit signal system, VOBC (on-board controller) needs to pre-store configuration files such as electronic maps of operating lines, and trains can only run on lines that have stored corresponding configuration files. [0003] Under the general trend of urban rail transit interconnection, more and more signaling systems can support cross-line operation of trains. "Trains can only run on lines that have stored corresponding configuration files" will become the main factor restricting the interconnection of signaling systems, [0004] Currently, trains must download configuration files for all possible lines before they are put into operation, and all configuration files are initialized during the system power-on initialization phase. ...
