Problems solved by technology

[0003] 1. Due to the serial port transmission technology itself, there are certain restrictions on the length of data and messages. In this way, when a message with a large amount of data is transmitted at one time, in order to avoid blocking other messages, the serial port will limit this message transmission. Therefore, the transmission requirements of large amounts of data will be limited and restricted
[0004] 2. The status of message reception is judged after all messages are sent. In this way, when transmitting large amounts of data, the user may wait for a long time before discovering that the data reception failed, which will waste a lot of time

Embodiment Construction

[0026] The present invention provides a method for resuming data transmission that is easy to be interrupted in the process of transmitting a message with a large amount of data, and the data transmission fails. After the message, send a message to the background device to query the transmission status. If the message replied by the background device indicates that the reception is successful, it will continue to transmit the next piece of data by default. If the background device fails to reply or does not receive the message from the background device, then proceed The prompt of failure information, and the user can choose whether to "resend" or "cancel". If "resend" is selected, the data that failed last time will be resent, and if "cancel" is selected, the current transmission will be aborted.

[0027] The implementation process of the present invention will be described below in conjunction with the accompanying drawings.

[0028] For the convenience of the following step...

Abstract

The related massive data safe transmission method between a maintenance terminal and background device comprises: segmenting the objective data, adding ACK message, and ensuring all information transmission success; if there is failure, using the terminal to know the failure, and selecting re-transmission or temporarily stopping. This invention improves data transmission security and reliability.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to the technical field of a method for securely transmitting a large amount of data between a maintenance terminal and a background device. Background technique [0002] Using the serial port for message transmission is easy to operate, not affected by network equipment, and will not cause message packet loss when transmitting data. It is especially suitable for the data security requirements of railway and military dispatching systems. Although this method of message transmission is The modern communication industry has been widely used, but it still has the following shortcomings: [0003] 1. Due to the serial port transmission technology itself, there are certain restrictions on the length of data and messages. In this way, when a message with a large amount of data is transmitted at one time, in order to avoid blocking other messages, the serial port will limit this messag...
