Abstract

The invention provides a data isolation method for a main line and a testing line in an urban mass transit line, and a communication device applied to the method, and relates to the technical field of communication. The method comprises the following steps: a TAU judges whether a destination IP address is the IP address of the testing line according to the destination IP address of data sent by a VOBC to a ZC; if the destination IP address is the IP address of the testing line, the TAU starts a GRE tunnel SC, closes a GRE tunnel ZX, and sends data to the ZC of the testing line through the SC; if the destination IP address is not the IP address of the ZC of the testing line, the TAU judges that the destination IP address belongs to a ZC network segment of the main line, starts the ZX, closes the SC, and sends the data to the ZC of the main line through the ZX so as to realize the data isolation of the main line and the testing line, wherein the urban mass transit line comprises a vehicle-mounted controller VOBC, a zone controller ZC and a communication device TAU. By adoption of the data isolation method provided by the invention, undesirable influence of the device operation of the testing line to the operation of a TAC network device of the main line can be avoided.

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...
