Embodiment Construction

[0016] The present invention will be described in further detail below.

[0017] A flow control method for offline files in the transmission of measurement and control data links. In the method, the data link terminal will regularly report the status of its own buffer area, and the measurement and control equipment will adjust the data flow rate of offline files according to the agreed step according to the reported status. When the cache area is almost full, the data link terminal will report the cache area is almost full in real time, and the measurement and control equipment will reduce the data flow rate of offline files until the real-time data transmission ends or the buffer area of ​​the data link terminal returns to the almost empty state.

[0018] Specifically, the method includes the following steps:

[0019] Step 1, the data link terminal regularly reports the status of its buffer area in the form of a status output message;

[0020] Step 2, each time the measureme...

Abstract

The invention discloses a flow control method of an offline file in measurement and control data link transmission, and belongs to the technical field of communication. According to the method, a datalink terminal reports the state of a cache region of the data link terminal at regular time, and measurement and control equipment adjusts the data flow rate of an offline file according to the reported state and agreed stepping. When the state of the cache region is about to be full, the data link terminal reports the quick full state of the cache region in real time, and the measurement and control equipment reduces the data flow rate of the offline file until real-time data transmission is finished or the cache region of the data link terminal recovers the quick empty state. By adopting the method, the data link terminal can interact with the measurement and control equipment, the state of the cache region of the data link terminal is reported in real time, the measurement and controlequipment can adjust the transmission rate of the offline file in real time, and the transmission time of the file is shortened. When the communication quality of the data link is poor or disconnected, the measurement and control equipment can stop sending the data stream to ensure the integrity of the file.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a flow control method for off-line files in the transmission of measurement and control data links. Background technique [0002] With the rapid development of measurement and control technology, the amount of data that needs to be transmitted through the data link is also increasing. The transmission of images and videos is even more common, and the data types are also diverse. Due to the limited bandwidth of the data link, the real-time transmission of the data link cannot satisfy the excessive data volume, so the transmission of offline files came into being. [0003] However, the transmission of offline files generally adopts a uniform data stream for transmission, and the transmission speed is relatively slow. In addition, when the quality of data link communication is poor or interrupted, data flow loss is prone to occur. Contents of the invention [0...
