Streaming data server, streaming media transmission method and data transmission system

Abstract

The invention discloses a streaming data server, which comprises a data receiving module, a preprocessing module, a standard data output module and a data pool, wherein the data receiving module is used for acquiring streaming data from data acquisition equipment, caching the acquired streaming data into a receiving buffer, and starting the preprocessing module after the streaming data is cached; the preprocessing module is used for converting the streaming data cached in the receiving buffer into a binary data stream, and writing the binary data stream into the data pool in a queue data structure; and the standard data output module is used for sequentially outputting the valid queue header data of the binary data stream in the data pool through an object linking and embedding for process control (OPC) standard interface. The invention also discloses a streaming data transmission method and a data transmission system. By the streaming data server, the streaming data transmission method and the data transmission system, the streaming data such as text data, image data and the like can be conveniently transmitted to a client, the unified access of the data can be realized, and remote bandwidth resources and field processing resources can be saved.

Description

technical field [0001] The invention relates to computer communication technology, in particular to a stream data server, a stream data transmission method and a data transmission system. Background technique [0002] Data acquisition equipment used to perceive field data, some output parameter data, some output text data, and some output image data (such as infrared light, visible light, X-ray, ultrasonic and tomographic imaging, etc.). [0003] As stream data, text data and image data are larger than ordinary parameter data, and are usually transmitted using multimedia data interface devices such as video, which will consume remote bandwidth resources and valuable on-site processing resources. [0004] In addition, at the scene of emergency detection, there is a large amount of short-term burst sensing data, large dynamic changes in the environment, a wide variety of sensing parameters, and a variety of data acquisition equipment interfaces that are not uniform, and requir...

Problems solved by technology

[0003] Text data and image data, as stream data, are larger than ordinary parameter data, and are usually transmitted using multimedia data interface devices such as video, which will consume remote bandwidth resources and valuable on-site processing resources

[0004] In addition, at the scene of emergency detection, the amount of short-term burst sensing data is large, the environment is dynamically changing, there are many types of sensing parameters, and the interfaces of data acquisition equipment are various and inconsistent, and fast deployment, fast startup, and fast networking are required. Wait

Conventional data transmission systems and methods cannot meet the data transmission requirements of emergency detection sites because they cannot realize the unified access and standardized output of a large number of data acquisition devices with different types of interfaces
