Embodiment 1

[0039] figure 1 is a schematic structural diagram of an example data transmission system according to an embodiment of the present invention, such as figure 1 As shown, the system may include: a plurality of signaling devices, configured to generate and send a plurality of encapsulated data packets; a DNS domain name server, configured to set and store the network address of each signaling device in the plurality of signaling devices and the corresponding The mapping relationship of the communication devices; and a plurality of communication devices, each of the plurality of communication devices is connected to one of the plurality of signaling devices, and is used to obtain the information from the DNS domain name server and transmit the multiple encapsulated data packets between the multiple signal devices according to the mapping relationship.

[0040] Specifically, for example, multiple signaling devices can be figure 1 The signal device A and the target signal device D...

Embodiment 2

[0049] figure 2 is a schematic structural diagram of an example data transmission device for signal equipment according to an embodiment of the present invention, such as figure 2 As shown, the apparatus may include: an encapsulation unit 11, configured to generate a first encapsulation data packet, the first encapsulation data packet includes the first network address and the first port number of the signaling device, and the second port number of the target signaling device. A network address and a second port number, and first data; and a sending unit 12, configured to send the first encapsulated data packet to the communication device, for example, using a local network protocol, such as UDP protocol, to send the first encapsulated data to the communication device .

[0050] Wherein, the first encapsulated data packet may include the first network address of the signaling device A, such as an Internet Protocol (IP) address and a first port number (such as figure 1 The ...

Embodiment 3

[0053] image 3 It is a schematic structural diagram of an example data transmission device 100 for signal equipment according to an embodiment of the present invention, such as image 3 As shown, in this embodiment 3, the difference from embodiment 2 is that, in addition to the encapsulation unit 11 and the sending unit 12, the apparatus may also include: a receiving unit 13 for receiving from the communication device B receiving the second encapsulated data packet generated by the target signal device D; and a decapsulating unit 14, configured to decapsulate the second encapsulated data packet to obtain the second data.

[0054] Wherein the second encapsulated data packet may include the first network address and the first port number of the signaling device A, such as an IP address and the first port number (for example, as figure 1 The IP address of the signal device A shown and its port number), the second network address and the second port number of the target signal d...

Abstract

The invention relates to the field of communication technology, and discloses a data transmission method, device and system. A data transmission method for signal equipment comprises the following steps: generating a first encapsulated data packet, wherein the first encapsulated data packet includes a first network address and a first port number of the signal equipment, a second network address and a second port number of target signal equipment, and first data; and sending the first encapsulated data packet to communication equipment, wherein the communication equipment can send the first encapsulated data packet to target communication equipment corresponding to the target signal equipment according to the mapping relationship between the second network address stored in a DNS domain name server and the corresponding target communication equipment. According to the data transmission method, device and system disclosed by the invention, the high-speed and reliable two-way data transmission between the signal equipment can be achieved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a data transmission method for signal equipment, a data transmission device for signal equipment, a data transmission method for communication equipment, and a data transmission method for communication equipment A data transmission device, and a data transmission system. Background technique [0002] In wheel-rail traffic, in order to ensure the safety of train operation, it is necessary to ensure that trains run at a certain safe interval. Under the traditional fixed block system, the system cannot know the specific position of the train in the zone, so the starting point and end point of the train braking are always at the boundary of a certain zone, which makes the safety interval between the trains larger and affects the efficiency of the line . The moving block technology uses uninterrupted two-way communication between the vehicle-mounted equipment and th...
