The requirement of higher transport capacity is difficult to meet due to the limited traction load capacity of the train pulled by the single locomotive. When a large transportation volume is needed, a plurality of locomotives are needed to be used for train reconnection, and the transportation capacity of the whole train is improved.
In a train reconnection, a locomotive operated by a driver is called a master control train, and a locomotive which obtains a control command through a train backbone device or system without being operated by the driver is called a slave control train. The mode of realizing the interaction of the control commands of the master control vehicle and the slave control vehicle and other data through wireless communication is called wireless reconnection. In wireless reconnection, the process of discovering the actual composition (topology) of a train is called train start operation.
When the train is in initial operation, the master control car needs to obtain the current sequence of each slave control car and determine the direction of each section of the train so as to configure the reconnection communication network and complete wireless reconnection. In the past, the parameters are manually configured, the length of a freight train is generally long, and manual operation is needed to go from the head to the tail of the train during manual configuration, so that time is consumed, and efficiency is low. Some technical schemes realize automatic configuration, but the technical schemes have the technical problems of more limiting conditions, more complex schemes, larger calculation amount, longer time consumption, easy connection with adjacent rail trains to cause misconnection and the like.
Some technical schemes for wireless reconnection of trains are proposed in the field, however, the following technical problems exist in the application of the technical schemes:
1) The technical scheme of manual configuration cannot automatically operate at the beginning, needs to manually configure train marshalling information, consumes long time and has low efficiency, or has poor automatic operation effect.
2) The technical scheme of train initial operation based on wireless ranging seriously depends on ranging precision and needs to preset more reference nodes. The calculation is carried out by the main node, the calculation amount is large, and the load of the main node is high. Therefore, the method is only suitable for determining the relative position between the trains in the wireless signal coverage range of two trains. In addition, under the condition that the adjacent tracks also have trains, the technical scheme of automatic train initial running based on wireless distance measurement easily causes misconnection, and reduces the success rate of initial running.
3) The technical scheme of the initial running of the train based on satellite positioning has long positioning time which is generally more than 30 s. And, require not sheltering from around the train during location to the requirement of train initial motion to adjacent rail vehicle discernment is difficult to satisfy to the positioning performance, is connected and is caused the misconnection with adjacent rail train easily, reduces initial motion success rate.
4) According to the technical scheme of the wireless backbone network based on the directional antenna, due to the existence of antenna side lobes, wireless signals transmitted by adjacent rail vehicles are easily received by the rail vehicles, so that the wireless signals are identified as the rail vehicles, the wireless signals are easily connected with the adjacent rail trains to cause error connection, and the success rate of initial operation is reduced.
5) The method for identifying the adjacent vehicles by means of the quality of the wireless signals easily causes identification errors or reduces the identification speed due to the interference of the wireless signals of the adjacent tracks, is easily connected with the adjacent track trains to cause misconnection, and reduces the success rate of initial running.
Aiming at the defects of the technical scheme, the automatic initial operation technical scheme based on the two-layer architecture is provided, and the automatic initial operation of the wireless train backbone network is realized.
According to the technical scheme, the method does not depend on external signals such as satellite positioning signals and the like, does not depend on ground positioning reference coordinate points, and does not depend on train distance measurement precision. The technical scheme disclosed by the invention has high success rate of initial operation, supports automatic initial operation of two or more vehicles, has higher flexibility, and effectively solves the technical problem of low success rate of automatic initial operation of trains in wireless reconnection.
In the present disclosure, a plurality of locomotives are grouped into a group of locomotives for coordinated operation. The first locomotive in the locomotive's forward direction is referred to as the master, i.e., the locomotive's driving operations are performed in the front cab of the master. The train backbone network device is arranged in each locomotive, and the hardware structures of the train backbone network devices of the locomotives are not obviously different. The difference is that the train backbone network device in the front-end cab of the master control train directly completes human-computer interaction, so the master train backbone network device is called, and all the rest train backbone network devices are called secondary train backbone network devices.
The present disclosure can achieve the following advantageous effects:
1) Automatic train topology discovery
The method realizes the decoupling of train topology discovery (access control) and wireless communication by utilizing a two-layer framework, does not need manual intervention when the train is in initial operation, and can automatically acquire the direction and the vehicle information of adjacent vehicles, thereby realizing the automatic discovery of the train topology.
2) Support automatic initial operation of a plurality of nodes
The wireless backbone network device in the disclosure can adapt to the initial operation of the train wireless backbone network under the condition of two or more vehicles.
3) Can stable realization train is automatic just moves
In other technical solutions, since wireless signals are circumferentially propagated in space and have poor directivity, and are easily received by wireless devices on nearby tracks, the wireless backbone network is easily connected to the wireless backbone network devices of vehicles on other tracks by mistake, resulting in failure of initial operation of the wireless backbone network. In the disclosure, because a two-layer architecture is adopted, and the connection topological relation of the wireless communication layer is controlled by the access control layer, the vehicle on the track can be effectively identified, and the failure of the initial operation of the wireless backbone network is avoided.
4) Adapting to multiple wireless communication technologies
The wireless communication layer in the device does not depend on a specific wireless communication mode and can adapt to various different wireless communication modes.
5) The requirement on the operation performance of the initially running hardware system is lower
The locomotive information is not directly acquired because the marshalling is carried out one by one in the method, so that the requirement on the computing performance of hardware is low.

The main train backbone network device sequences train marshalling, vehicle directions and the like according to the access control information, realizes train topology discovery to obtain train topology, and generates a train network index according to the train topology. When the train backbone network device of the first train is a main train backbone network device, the train backbone network device of the second train is a secondary train backbone network device. When the train backbone network device of the second train is the main train backbone network device, the train backbone network device of the first train is the secondary train backbone network device.
In this embodiment, the access control layer of the backbone network device interacts with the wireless communication layer to obtain a train network index, and the wireless communication layer configures a wireless access relationship and a wireless communication parameter between the master control train and the slave control train according to the train network index, so as to realize automatic networking of the train wireless backbone network, thereby realizing initial operation of the train wireless backbone network.
