Abstract

The invention relates to a group semantic message filtering and routing method of a distributed self-organizing structure. Manufacturing resources subscribe topic messages to a message bus according to process characteristics, and send the generated messages to the message bus; the message bus adopts a method based on TES‑FRA‑DNTB The algorithm filters and routes the received messages; adds the processed messages to the message cluster, and compresses the message cluster; publishes the compressed message cluster to the manufacturing resources corresponding to the subscribed topic. The self-organizing system structure adopted by the present invention has load balancing function, and each manufacturing resource is an independent message node, which has strong fault tolerance and scalability, and realizes automatic restart for abnormally exiting faulty nodes, which has strong robustness ; The message filtering and routing algorithm TES‑FRA‑DNTB based on the similarity between subscriber topics and feature values ​​can handle large-scale messages and has high real-time performance, meeting the performance requirements in intelligent manufacturing.

Description

technical field

[0001] The invention relates to the field of computer system data transmission, in particular to a group semantic message filtering and routing method of a distributed self-organizing structure. Background technique

[0002] The future industrial manufacturing market will mainly focus on intelligent manufacturing. It is the general trend to build intelligent production lines in an all-round way and complete the transformation from manufacturing to intelligent manufacturing.

[0003] Traditional manufacturing control systems mostly adopt central control architecture or hierarchical control architecture. They all adopt the internal control method of master-slave instruction control, that is, the controlled object should report its status to the superior controller and take actions completely according to the instructions issued by the superior controller. The central control unit has global information after collecting the status reports of each lower-level co...

Examples

Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] figure 1 It is a flow chart of the method of the present invention.

[0036] The method of the present invention adopts a distributed self-organizing system structure, and manufacturing resources such as management and control systems, equipment, personnel, and materials in the production workshop in intelligent manufacturing can freely choose to join or exit the message bus system, and each manufacturing resource object is used as an independent message node. The bus is responsible for maintaining the list of online message nodes and the message topics subscribed by each node. The heartbeat protocol is used to realize the global state information between each message node, and it can perform load balancing and restart the faulty node. For the subscription content of each message node, the filtering and routing algorithm TES-FRA-DNTB b...
