CPS (Cyber-Physical Systems) node function parameter access method

Abstract

The invention discloses a CPS (Cyber-Physical Systems) node function parameter access method. The method is characterized in that a function data address mapping table of CPS slave nodes is established in a CPS master node, and the CPS master node can use a unified mode to access CPS slave node function data through the established address mapping table. According to the CPS node function parameter access method of the invention, a standardized method of CPS node data accesses is provided on the basis of attribute space of a UM-BUS bus, heterogeneous access capability and access specificationof the CPS nodes can be improved, and standardized upgrading maintenance of CPS is facilitated.

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.
