Problems solved by technology

[0004] However, the implementation process of backbone network address reconfiguration is cumbersome and complicated. It is necessary to ensure the existence of backbone network nodes, and at the same time, backbone network nodes need to perform a large number of initial operation calculations, which makes the realization of reconnection difficult and slow. failure rate

Embodiment 1

[0055] Embodiment 1 discloses a data forwarding method, which is applied to a first gateway device, and the first gateway device is a device in the first formation network of a train. Refer to figure 1 , the method includes:

[0056] S101: Receive a data object.

[0057] The data object includes the target data to be forwarded and the source address and destination address of the target data, the source address and the destination address include a marshalling identifier and a device number, and the marshalling identifier is a self-organizing identifier representing a corresponding device number It points to the equipment in the first marshalling network, and the said marshalling identifier indicates that the corresponding device number points to the device in the second marshalling network.

[0058] The present invention predefines two concepts of self-marshalling and other-marshalling for the actual situation that only the inter-network communication between the two marshal...

Embodiment 2

[0076] The embodiment has described in detail the inter-network communication process of the data forwarding method of the present invention, and the second embodiment continues to supplement the intra-network communication, refer to figure 2 , the data forwarding method of the present invention also includes:

[0077] S104: When the composition identifier in the source address of the data object is a self-organization identifier and the composition identifier in the destination address is a self-organization identifier, send the data object to the destination address in the first marshalling network The device pointed to by the device number.

[0078] For example, if the marshalling identifier in the source IP address and destination address of the data object are both 000, it means that the source device and the destination device of the data object are both devices in the marshalling group. At this time, the gateway device is only used as a transit device to directly trans...

Embodiment 3

[0080] Embodiment 3 discloses a gateway device, and the gateway device is based on the data forwarding method disclosed in the above embodiments.

[0081] Corresponding to embodiment one, refer to image 3 , the gateway device includes a receiving module 101 , a first sending module 102 and a second sending module 103 .

[0082] The receiving module 101 is configured to receive a data object, the data object includes the target data to be forwarded and the source address and the destination address of the target data, the source address and the destination address include a group identification and a device number, and the group identification The self-organization identification indicates that the corresponding equipment number points to the equipment in the first formation network, and the formation identification indicates that the corresponding equipment number points to the equipment in the second formation network for other formation identifications;

[0083] The first ...

Abstract

The invention discloses a data forwarding method. According to the data forwarding method, two concepts including self-consist and other consist are predefined, and a self-consist identifier and the other consist identifier are correspondingly defined as a distinguishing basis of affiliation conditions of a device in two consist networks, meanwhile, a conversion condition between the two identifiers is defined, different identifier conversion and forwarding processing can be carried out on a data object according to affiliation conditions of source and target devices subsequently represented by the consist identifiers so as to provide a support for communication between the networks. The invention also discloses gateway equipment bearing the method and a train reconnection system suitable for two trains with single consist networks only. The train reconnection system comprises two consists, wherein each consist only includes one consist network, each consist comprises the gateway equipment, and the two consists are communicated between the consist networks through the gateway equipment. The data forwarding method, the gateway equipment and the train reconnection system do not need dynamic preliminary operation calculation and distribution of an address of a backbone network, and the reconnection process is simple, quick and low in fault rate.

Description

technical field [0001] The invention belongs to the technical field of train reconnection, and in particular relates to a data forwarding method, a gateway device and a train reconnection system. Background technique [0002] Train reconnection refers to the connection of two or more independent trains into an independent train through certain operations, and at the same time ensures that the original train communication network of each independent train can carry out normal inter-network communication. The train communication network is A network that connects various on-board equipment in the train system to realize functions such as train control and diagnosis. [0003] The existing train communication network consists of a marshalling network and a backbone network. The marshalling network is a communication network that connects on-board equipment in the train marshalling to realize data communication. Each device in the marshalling network is configured with a constant...
