Embodiment 1

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

[0062] (1) Before the ACARS message is transmitted in blocks, the sending end sends a Multi-block_Transfer_Req message to negotiate with the receiving end on the size of the message and the valid time for the message to be transmitted in the network.

[0063] (2) The receiving end makes the following response to the multi-block transfer negotiation requested by the sending end according to the storage resources:

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

[0065] Such as Figure 4 As shown, or send a Multi-block_Transfer_Accept message to accept a multi-block message transfer request, and specify the minimum sending interval between...

Embodiment 2

[0075] Embodiment 2: An 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 on the size of the message and the effective time of message transmission in the network before the ACARS message is transmitted in blocks.

[0077] The receiving module is configured to make the following response to the multi-block transfer negotiation requested by the sending module according to the storage resource:

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

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

[0080] The system also includes a multi-block transfer initiation timer. The multi-block transfer initiation timer is used to time the maximum time for the sending module...

Abstract

The invention discloses an air-ground ACARS message transmission method and system based on file transmission, relates to the aviation data transmission field. According to the technical scheme, the method comprises the steps that before ACARS message block transmission, a sending end sends a Multi-block_Transfer_Req message to negotiate with a receiving end about the size of the message and the effective time of message transmission in a network; and the receiving end makes the following response to the multi-block transmission negotiation requested by the sending end according to the storageresources: sending a Multi-block_Transfer_Abort_Req message to refuse to carry out multi-block message transmission; or, sending a Multi-block_Transfer_Accept message to accept a plurality of messagetransmission requests, and specifying the minimum sending interval time between the message blocks, so that the problems of invalid transmission, waste of network resources, relatively low channel utilization rate, channel overload, resource insufficiency and the like which are easily caused when the ARINC 618 protocol sends a plurality of block messages in the prior art are solved.

Description

technical field [0001] The invention relates to the field of aviation data transmission, more specifically, it relates 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, Aircraft Communications Addressing and Reporting System) message transmission follows the ARINC 618 protocol. [0003] Such as figure 1 and figure 2 As shown, the ARINC 618 protocol divides air-to-ground ACARS message transmission into two categories according to the 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 with a length of 0 to 210 characters is called a single block message (Single Block Message); a downlink message with a length of 221 to 3520 characters, or 211 to 3440 An uplink message of characters ne...
