A cps node function parameter access method

Abstract

A kind of CPS node function parameter access method, it is characterized in that: set up the function data address mapping table of CPS slave node in CPS master node, CPS master node can adopt unified mode to CPS slave node function data by the established address mapping table to visit. The CPS node function parameter access method of the present invention is based on the attribute space of the UM-BUS bus, and provides a standardized method for CPS node data access, which can improve the heterogeneous access capability and access normativeness of the CPS node. It is conducive to the standardized upgrade and maintenance of the CPS system.

Description

technical field [0001] The invention relates to a data access method of a cyber-physical system (CPS), in particular to a method for storing and accessing functional parameter data between CPS nodes. Background technique [0002] Cyber-Physical Systems (hereinafter referred to as CPS) is a new generation of intelligent systems that integrate information processing and physical perception execution through the organic combination of computing, communication and control technologies, and realize the coordination of computing resources and physical resources. CPS improves the system's capabilities in information processing, real-time communication, remote precise control, and automatic component coordination through a series of highly integrated and interactive computing units and physical objects in a network environment. It is a space-time, multi-dimensional heterogeneous hybrid autonomous system. , with real-time, safe, reliable, high-performance and other characteristics. ...

AI Technical Summary

Problems solved by technology

However, in a large number of industrial production sites, embedded control and other fields, due to the constraints of factors such as noise, signal attenuation, and message conflicts, it is difficult for wireless sensor networks to meet application requirements in terms of real-time performance, accuracy, and reliability.

The traditional embedded distributed processing system based on bus network connection lacks sufficient support in terms of bus speed, fault tolerance, node synchronization, heterogeneous expansion, etc., and it is also difficult to meet the needs of CPS in heterogeneous access, dynamic connection, and reliability. , real-time and other aspects of development needs

At the same time, most of the various wireless networks and high-speed buses lack interrupt support between devices, and it is difficult to provide good support for fast real-time response to events between devices in CPS applications.
