Embodiment 1

[0091] figure 1 It is a schematic diagram of a train load balancing system provided by Embodiment 1 of the present invention, such as figure 1 As shown, the structure of the train load balancing system includes: at least one target train 110, at least one load train 120 and base 130, wherein:

[0092] The target train 110 maintains a communication connection with each load train 120 and the base 130, and is used to perform fragmentation processing on the base-side target message sent to the base 130 to obtain multiple uplink fragmented messages, which are determined according to each uplink fragmented message Uplink load fragmentation message and uplink local fragmentation message, and send the uplink load fragmentation message to the load train 120, and send the uplink local fragmentation message to the base 130; or receive the downlink local fragmentation message sent by the base 130 The fragmented message and the downlink load fragmented message sent by the load train 120 ...

Embodiment 2

[0101] figure 2 It is a flow chart of a train load balancing method provided by Embodiment 2 of the present invention. This embodiment is applicable to the situation where the target train uses each load train to send messages to the base. This method can be executed by the target train and is connected with the load The train and the base cooperate to complete. Correspondingly, such as figure 2 As shown, the method includes the following operations:

[0102] S210. Obtain the base-side target message sent to the base, and perform fragmentation processing on the base-side target message to obtain multiple uplink fragmented messages.

[0103] In an optional embodiment of the present invention, before the fragmentation processing of the target message on the base side, it may include: updating the source IP address of the target message on the base side to the IP address of the target train The IP address of the external network; performing three-layer header processing on t...

Embodiment 3

[0127] image 3 It is a flowchart of a train load balancing method provided by Embodiment 3 of the present invention. This embodiment is applicable to the situation where a loaded train sends a message to a base. This method can be executed by a loaded train and completed in cooperation with the target train and the base. . Correspondingly, such as image 3 As shown, the method includes the following operations:

[0128] S310. Receive the uplink load fragment message sent by the target train; the uplink load fragment message is obtained by the target train according to the fragment processing of the base side target message sent to the base. The text is confirmed.

[0129] S320. Send the uplink load fragmentation message to the base.

[0130] In the embodiment of the present invention, after receiving the uplink load fragmentation message sent by the target train, the load train may send the uplink load fragmentation message to the base.

[0131] In an optional embodiment...

Abstract

The embodiment of the invention discloses a train load balancing system and method, a train system and a base system. The system comprises at least one target train, at least one load train and a base, wherein the target train is used for fragmenting a base side target message to obtain an uplink fragmented message so as to determine that a uplink load fragmented message and an uplink local fragmented message are sent to the load train and the base, and assembling areceived downlink local fragmented message and a downlink load fragmented message to obtain a train side target message; the loadtrain is used for receiving the uplink load fragmented message and the downlink load fragmented message and sending the uplink load fragmentated message and the downlink load fragmented message to thebase and the target train; the base is used for assembling the received uplink load fragmented message and the uplink local fragmented message to obtain a base side target message, and fragmenting the train side target message to obtain a downlink fragmented message so as to determine that the downlink load fragmented message and the downlink local fragmented message are sent to the target trainand the load train.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of train networks, and in particular to a train load balancing system and method, a train system and a base system. Background technique [0002] At present, the communication between trains is wired, and the communication between trains and fixed bases is wireless. The entire train uses the command car as a transfer station to communicate with the base, and then communicate with other trains. In order to prevent the fault of the command vehicle from causing the communication failure of the entire train, each train is equipped with wireless communication equipment. When the command vehicle fails, other trains can become the new command vehicle to ensure that the train as a whole continues to work normally. [0003] In the process of implementing the present invention, the inventor found that the existing technology has the following defects: if multiple trains need to communicate with ...
