Cross-platform lightweight distributed control system

Abstract

The invention discloses a cross-platform lightweight distributed control system, which comprises a plurality of device nodes; each device node comprises a memory module, an interaction-providing interface between cross-platform lightweight modules, a loading module and a communication module, wherein the memory module is used for creating a module instance and a module interface instance for each cross-platform lightweight module and storing the module instance and the module interface instance of each cross-platform lightweight module, each cross-platform lightweight module is an independent dynamic link library DLL or a shared library SO providing an interface for the outside, the loading module is used for loading all the cross-platform lightweight modules in an application, and the communication module is used for carrying out data exchange and service invocation between different applications or the different device nodes in the distributed control system. The invention can ensure that the distributed control system can realize a source code-level cross-platform.

Description

technical field [0001] The invention relates to the field of control, in particular to a cross-platform lightweight distributed control system. Background technique [0002] Whether it is the distributed control system (DCS) in industrial process control, the power station computer system (KIT) in nuclear power plants, or the large-scale supervisory control and data acquisition system (SCADA) used in rail transit, two core issues are involved, namely, software The componentized architecture and the communication problems between the various services of the system brought about by distributed data collection and centralized computing. At the same time, with the expansion of applications, engineering has higher and higher requirements for system deployment flexibility, platform dependence, and scalability. [0003] This raises a very real question: how to build a cross-platform and complete CPDSFI (Cross Platform Distributed Software framework Infrastructure, distributed basi...

Problems solved by technology

[0006] (1) Problems such as undisclosed codes or too complicated standards require considerable customization before they can be applied to industrial control occasions

Although each manufacturer provides a lot of information and related sample codes, if you want to master these technologies proficiently, apply them in the development process, and accurately locate and analyze problems when they occur, you need to have a thorough understanding of the working mechanism of the standard, plus The complexity of the DCS system itself, the risks here are difficult to control

[0007] (2) None of the current mainstream DCS control system software has achieved source-level cross-platform

The same system cannot support multiple operating systems at the same time, which is not conducive to the vertical and in-depth development of control system software

Most of the current DCS control system software runs on the Windows platform. Due to the loopholes of the platform itself, the system often needs to be anti-virus, which increases the cost of maintenance.
