Embodiment Construction

[0054] The data synchronization method of the embodiment of the present invention integrates the message synchronization modules in the prior art to obtain an information synchronization code library (hereinafter referred to as IsLib) suitable for all distributed programs in the embedded distributed system. The function of IsLib is clear and single, and distributed programs with synchronization requirements only need to use the interface provided by this IsLib to realize data synchronization. The distribution of IsLib in the embedded distributed system is as follows: Figure 7 shown. The embodiment of the present invention abstracts the application data change message notification mechanism originally belonging to different distributed programs such as the third distributed program 71, the fourth distributed program 72, the fifth distributed program 73, and the sixth distributed program 74. IsLib75 makes each distributed program no longer need to have a separate synchronous m...

Abstract

The invention relates to an embedded distributed system data synchronization method and a embedded distributed system, and the method comprises steps that: an information synchronization code base which is used for releasing and synchronizing data is built on an inter-process communication layer of the embedded distributed system; a program with data source disposed in the embedded distributed system releases data by the information synchronization code base; and a program with data to be synchronized in the embedded distributed system synchronizes the data released by the program with the data source disposed by the information synchronization code base, thus generating mirror image data. The system comprises the program with the data source disposed, the program with the data to be synchronized and the information synchronization code base comprising a server interface, a server end, a client interface and a client end. By the establishment of the information synchronization code base and the adoption of the information synchronization code base for data synchronization, a unified data synchronization mechanism can be achieved, the code redundancy can be greatly reduced, and maintainability and scalability of the data synchronization mechanism can be improved.

Description

technical field [0001] The invention relates to the technical field of methods for synchronizing embedded distributed information, in particular to a method for synchronizing data in an embedded distributed system and the embedded distributed system. Background technique [0002] An embedded distributed system is an embedded system that executes tasks on a multiprocessor architecture interconnected by a communication network, including distributed programs. A distributed program refers to a program that is generated based on modular design considerations or because the program is deployed on different hardware carriers, and multiple program modules cooperate to complete a specific function, including core programs and application programs. Distributed programs are spatially located in the distribution of embedded distributed systems. These distributions can be software space or hardware space. [0003] The distributed program adopts the method of directly accessing the dat...
