The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a data isolation method between a main line and a test line in an urban rail transit line according to an embodiment of the present invention. As shown in fig. 1, a method for isolating data of a main line and a test line in an urban rail transit line according to an embodiment of the present invention includes:
in step S101, the TAU determines whether the destination IP address is the IP address of the ZC of the taxi-test line according to the destination IP address of the data sent by the VOBC to the ZC.
Specifically, prior to this step, the method further comprises: configuring a GRE tunnel ZX from the TAU to the main line for the TAU, and configuring a network segment route from the TAU to the ZC of the main line for the TAU aiming at the ZC of the main line, wherein a route interface is the GRE tunnel ZX; and configuring a GRE tunnel SC from the TAU to the test line for the TAU, and configuring a host route from the TAU to the ZC of the test line for the TAU aiming at the ZC of the test line, wherein a route interface is the GRE tunnel SC.
The urban rail transit line comprises a vehicle-mounted controller VOBC, a zone controller ZC and a communication device TAU.
Next, in step S102, if the destination IP address is the IP address of the ZC of the test line, the TAU starts a GRE tunnel SC, closes a GRE tunnel ZX, and sends data to the ZC of the test line through the SC.
Finally, in step S103, if the destination IP address is not the IP address of the ZC of the test line, the TAU determines that the destination IP address belongs to the ZC segment of the main line, activates the ZX, closes the SC, and transmits data to the ZC of the main line through the ZX, thereby realizing data isolation between the main line and the test line.
In a specific implementation manner, a communication device TAU is respectively configured with a GRE tunnel ZX to a main line and a GRE tunnel SC to a trial run line, a segment route is configured on the TAU for a ZC of the main line, and a route interface is the GRE tunnel ZX, so that data of an onboard controller is ensured to be correctly sent to the ZC of the main line. And configuring a host route on the TAU for the ZC of the test line, wherein a route interface is a GRE tunnel SC, and the data of the vehicle-mounted controller is ensured to be correctly sent to the ZC of the test line. And according to the destination IP address of the data sent to the ZC by the VOBC, enabling the corresponding GRE tunnel by the TAU and closing the other GRE tunnel. Specifically, if the destination address is the IP address of the test run line ZC, the TAU starts the GRE tunnel SC and closes the GRE tunnel ZX; if the destination address belongs to the ZC network segment of the main line, the TAU starts a GRE tunnel ZX and closes a GRE tunnel SC, so that the aim of isolating the data of the main line and the test line is fulfilled. Therefore, the communication equipment in the LTE equipment can start a plurality of tunnels, and the main line can be isolated from the test run line through the tunnel technology.
Preferably, the urban rail transit line further comprises: LTE core network equipment EPC, the method further comprises: under the condition of receiving the data transmitted by the GRE tunnel SC, the EPC forwards the data transmitted by the GRE tunnel SC to the vehicle test line through a data interface arranged by the EPC; and under the condition of receiving the data transmitted by the GRE tunnel ZX, the EPC forwards the data transmitted by the GRE tunnel ZX to the positive line through another data interface arranged by the EPC, so that the data isolation of the positive line and the test line is realized inside the EPC.
In a specific embodiment of the present invention, an LTE core network device EPC of an LTE system provides an SGI data interface for a main line in an ATC network of an urban rail transit line, and also provides another SGI data interface for a test run line in the ATC network of the urban rail transit line, where the two data interfaces are independent physical interfaces. In addition, the LTE system ensures that two SGI interfaces respectively reach ZCs of a main line and a test line to have different data flow directions, and ensures that data isolation between the main line and the test line is realized inside the EPC.
Preferably, the urban rail transit line further comprises: the LTE core router and the LTE test route router, the method further comprises the following steps: configuring a network segment route for the ZC of the main line, wherein a route interface points to the LTE core router arranged on the main line; and configuring a host route for the ZC of the test line, wherein a route interface points to an LTE test line router arranged on the test line. The LTE core router and the LTE commissioning line router are both routers supporting GRE. Therefore, physical isolation between the router of the positive line and the router of the test traffic line can be ensured.
Preferably, the urban rail transit line further comprises: the method comprises the following steps that: configuring a first access control list for the automatic train control switch of the main line so that data transmitted by the ZC of the train test line in the automatic train control network of the urban rail transit line cannot reach the ZC of the main line and the automatic train control switch of the station; and configuring a second access control list for the automatic train control switch of the train test line so that the data sent by the ZC of the positive line in the automatic train control network of the urban rail transit line cannot reach the ZC of the train test line. The automatic train control switch of the main line and the automatic train control switch of the test line are switches with three-layer switching functions. Thus, in a wired network, the positive line and the test line are only connectable in parts of the computer interlock system and not connectable in parts of other subsystems, including the automatic train control network (ATC).
In an alternative embodiment of the invention, the wired network of the main line and the test line requires that no other subsystems are connectable except the computer interlock system. At this time, the wired network of the main line and the test line cannot realize physical isolation, and the isolation of the test line and the main line and the data communication of the computer interlocking system can be realized only by adopting an Access Control List (ACL) mode. Since the ACL can be configured only by the switch having the three-layer switching function, the data broadcasted by the main line and the test run line can be isolated.
Fig. 2 is a schematic diagram of data isolation between a main line and a test run line in an urban rail transit line according to an embodiment of the present invention. As shown in fig. 2, the vehicle-mounted controller VOBC first transmits data to be transmitted to the ZC of the forward line or the test line to the vehicle-mounted three-layer switch. Then, the vehicle-mounted three-layer switch sends the data to a communication device TAU at the tail of the vehicle according to the stored routing table, the TAU enables a corresponding GRE tunnel according to the destination IP address of the data, closes another GRE tunnel, and sends the data to the ground base station through the corresponding tunnel, the ground base station forwards the data to LTE core network equipment EPC through the LTE switch, and the EPC obtains the destination IP address through analysis according to the received data. If the destination IP address is the IP address of the ZC of the positive line, the EPC forwards the data, and the data sequentially pass through the LTE switch, the LTE core router, the parking lot ATC switch and the ATC switch of the corresponding station to reach the corresponding zone controller ZC. If the target IP address is the IP address of the ZC of the test line, the EPC forwards the data, and the data sequentially reach the ZC of the test line through the LTE test line router and the ATC switch of the test line. Therefore, the vehicle-mounted controller of the train can communicate with the zone controller ZC of the test run line through the wireless network when the test run line is carried out, and the vehicle-mounted controller of the train can communicate with the zone controller ZC of the main line through the wireless network when the vehicle-mounted controller of the train is on the main line. In addition, the parking lot ATC switch is configured with a first access control list, data sent by the ZC of the test line cannot reach the ATC switch and the zone controller ZC of the corresponding station, the ATC switch of the test line is configured with a second access control list, and data sent by the ZC of the positive line cannot reach the zone controller ZC of the test line. Therefore, the isolation of the wired network of the positive line and the test line is realized.
In this embodiment, the communication device TAU judges whether or not the destination IP address is the IP address of the zone controller ZC of the test lane based on the destination IP address of the data sent from the VOBC to the zone controller ZC, in the case where the destination IP address is judged to be the IP address of the zone controller ZC of the test line, the communication device TAU activates the GRE tunnel SC, closes the GRE tunnel ZX and sends the data through the GRE tunnel SC to the zone controller ZC of the test line, in the case where it is judged that the destination IP address is not the IP address of the zone controller ZC of the test line, the communication equipment TAU judges that the destination IP address belongs to the ZC segment of the main line, and activates the GRE tunnel ZX, closes the GRE tunnel SC, and transmits the data to the ZC of the main line through the GRE tunnel ZX, therefore, data isolation between the main line and the test run line is realized, and adverse influence of equipment operation of the test run line on operation of the ATC network equipment of the main line can be effectively avoided.
