CPS (Cyber-Physical Systems) master node dynamic-identification method based on UM-BUS bus

Abstract

The invention discloses a CPS (Cyber-Physical Systems) master node dynamic-identification method. The method is characterized in that a CPS master node M0 sends an identification request to all CPS nodes on a bus through a global interruption request after time synchronization is completed, other CPS master nodes complete identification on the master node M0 through reading configuration information of the master node M0, and a function parameter reading / writing access mapping table and a method mapping table are established for the master node M0 in memory thereof. At the same time, all the other nodes can also return identified interruption requests to the master node M0, and using the interruption requests, the master node M0 completes dynamic identification on the other nodes through reading configuration space of the other nodes. According to the CPS master node dynamic-identification method of the invention, a CPS node dynamic-identification and access method is provided, plug-and-play and driverless accesses of CPS node equipment are supported, and heterogeneous access capability and access specification of the CPS nodes can be improved.

Description

technical field [0001] The invention relates to a method for organizing functional modules of a cyber-physical system (CPS), in particular to a method for dynamically connecting and identifying 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.

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.
