Embodiment 1

[0061] Embodiment 1: the air-ground ACARS message transmission method based on file transmission, comprises the following steps:

[0062] (1) Before the ACARS message is transmitted in blocks, the sender sends a Multi-block_Transfer_Req message to negotiate with the receiver the size of the message and the effective time for the message to be transmitted in the network.

[0063] (2) The receiver makes the following responses to the multi-block transmission negotiation requested by the sender according to the storage resources:

[0064] like image 3 As shown, if the storage resources of the receiving end are not enough to receive a message of the size specified in Multi-block_Transfer_Req, Multi-block_Transfer_Abort is used to refuse multi-block message transmission.

[0065] like Figure 4 shown, or issue a Multi-block_Transfer_Accept message to accept a multi-block message transfer request and specify the minimum transmission interval between message blocks.

[0066] like...

Embodiment 2

[0075] Embodiment 2: The air-to-ground ACARS message transmission system based on file transmission, including:

[0076] The sending module is used to send a Multi-block_Transfer_Req message to negotiate with the receiving module the size of the message and the effective time for the message to be transmitted in the network before the ACARS message is transmitted in blocks.

[0077] The receiving module is used to make the following responses to the multi-block transmission negotiation requested by the sending module according to the storage resources:

[0078] Send a Multi-block_Transfer_Abort message to refuse multi-block message transmission;

[0079] Or, issue a Multi-block_Transfer_Accept message to accept a multi-block message transfer request and specify the minimum transmission interval between message blocks.

[0080] The system also includes a multi-block negotiation timer. The multi-block negotiation timer is used to time the maximum time that the sending module w...

Abstract

The invention discloses an air-ground ACARS message transmission method and system based on file transmission, and relates to the field of aviation data transmission. The effective time of transmission in the network; the receiver responds to the multi-block transfer negotiation requested by the sender according to the storage resources: send a Multi-block_Transfer_Abort message to reject multi-block message transfer; or send a Multi-block_Transfer_Accept message to accept multi-block message transfer request, and specify the minimum sending interval between message blocks, which solves the problems in the prior art when the ARINC 618 protocol sends multi-block messages, which is easy to cause invalid transmission, waste of network resources, low channel utilization, channel overload, and insufficient resources. And other issues.

Description

technical field [0001] The present invention relates to the field of aeronautical data transmission, and more particularly, to an air-ground ACARS message transmission method and system based on file transmission. Background technique [0002] The current data link air-ground ACARS (Aircraft Communications Addressing and Reporting System) message transmission follows the ARINC 618 protocol. [0003] like figure 1 and figure 2 As shown, the ARINC 618 protocol divides air-to-ground ACARS message transmissions into two categories based on message length: single-block message transmission and multi-block message transmission. Among them: a downlink message with a length of 0 to 220 characters, or an uplink message of 0 to 210 characters is called a single block message; a downlink message with a length of 221 to 3520 characters, or 211 to 3440 The upstream message of characters needs to be split into multiple message blocks (2 to 16) for transmission due to its long length, ...
