Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0025] The present invention adopts C / S architecture, wherein the initiator and receiver of the data exchange are the client (Client end), the data exchange processing party is the server end (Server end), the Server end only faces the Client end, and the actual data exchange is for both parties Said to be transparent. Since the method takes both local area and wide area network environments in...

Abstract

The invention discloses a real-time exchange method of distributed experimental data. The method involves an initiator, a receiver and a processor of data, and comprises the following steps: creatinga system model file, requesting a local model file, updating a local model data structure, initiating data update, refreshing an update queue, receiving data update, forwarding the data update, and receiving the data. According to the real-time exchange method of distributed experimental data, a part of the technical features of OPC and DDS is absorbed, a lightweight unified hardware and softwareinterface, a common data exchange process and a consistent data management architecture are provided, so that various kinds of tested and test equipment (comprising physical equipment and software systems) can be very lightly integrated and freely exchange data. The system interface is simple, the configuration and deployment are convenient, and flexible and varied test site requirements can be better adapted to.

Description

technical field [0001] The invention belongs to the field of computer application technology, and more specifically relates to a method for exchanging distributed test data in real time. Background technique [0002] Distributed test data refers to information produced or consumed by physical equipment and software used for testing in a local or wide-area environment. Physical equipment includes sensors, actuators, controllers, other intelligent equipment, industrial control systems, etc., and software includes simulation software, simulation software, human-computer interaction software, etc. The real-time exchange of test data is the foundation and core of realizing test process automation. Many processes such as collection, transmission, monitoring, processing, feedback, and release of test data require the support of unified data exchange strategies, protocols, and methods, so as to realize the seamless connection and vertical integration of machines and information sys...
