Real-time data bus management method and system for intelligent body collaboration system

Abstract

The present invention is a real-time data bus management method and system oriented to an intelligent body collaboration system, the method comprising: constructing a real-time data bus with data subscription and distribution services, and establishing a state and data transmission control for monitoring each bus access node QoS information; receive the configuration information of the QoS information of each bus access node, and control the transmission, encapsulation, read and write operations of the message and the configuration of the shared memory according to the configuration information of the QoS information, so as to control the status of each bus access node Perform unified monitoring and management. The invention has the advantages of simple realization principle, unified planning management and distributed automatic configuration of the bus, and high real-time performance and reliability.

Description

technical field [0001] The present invention relates to the technical field of intelligent body collaboration systems, in particular to a real-time data bus management method and system for intelligent body collaboration systems. Background technique [0002] The main feature of the distributed real-time control system is to realize the data collection and analysis of sensors, controllers and other equipment with widely distributed physical locations through a reliable communication network, as well as operations such as remote control, telemetry, remote adjustment, and remote signaling. Electric power distribution network automation, scheduling automation and other systems, such systems have higher requirements in terms of reliability, real-time performance and fault tolerance than traditional applications. Traditional distributed control systems generally adopt a closed customization mode, that is, software is designed according to specific application requirements, and it...

Problems solved by technology

The current research on real-time SOA is still in its infancy, and the existing research is usually based on the real-time SOA architecture itself, and the real-time SOA model must solve the following problems: (1) the abstraction and encapsulation method of real-time services; (2) to ensure The real-time and reliability of service processing, that is, the real-time problem is the basic problem that real-time SOA must solve. At present, there is no effective solution to solve this problem.

Some practitioners have proposed a real-time-enhanced SOA architecture for industrial control systems, but this architecture is still a QoS-oriented communication middleware in essence, mainly including two layers, the protocol layer and the API layer, and has not yet been able to solve the specific problems of real-time performance.
