Abstract

The invention provides a data isolation method for a main line and a test line in an urban rail transit line and a communication device used for the method, and relates to the technical field of communication. Wherein, the method includes: the TAU judges whether the destination IP address is the IP address of the ZC of the test line according to the destination IP address of the data sent by the VOBC to the ZC; If the IP address of the ZC of the test line, the TAU enables the GRE tunnel SC, closes the GRE tunnel ZX, and sends data to the ZC of the test line through the SC; if the destination IP address is not the ZC of the test line IP address, the TAU judges that the destination IP address belongs to the ZC network segment of the main line, and enables the ZX, closes the SC, and sends data to the ZC of the main line through the ZX , thereby realizing data isolation between the main line and the test line, wherein the urban rail transit line includes an on-board controller VOBC, a zone controller ZC, and a communication device TAU. Through the present invention, it is possible to prevent the operation of the equipment on the test line from adversely affecting the operation of the ATC network equipment on the main line.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data isolation method for a main line and a test line in an urban rail transit line and a communication device used for the method. Background technique [0002] The test line of the urban rail transit line refers to the line where the dynamic performance test of the vehicle is carried out, and its line standard should generally be consistent with that of the main line. At present, three networks of ATC (Automatic Train Control, automatic train control) dual network (ATC red network and ATC blue network) and MSS network are set up on the test line. Since the management of the equipment room of the test line is not as strict as the management of the equipment room of the main line, there are risks of personnel other than signal professionals, such as vehicle professionals, entering the equipment room of the test line, which will cause network plugging, USB disk access, an...
