A general data router and its communication method

Abstract

The present invention provides a general data router and a communication method thereof. The general data router is configured with a communication-driven dynamic library and a plurality of nodes, and uses a thread pool mode to dynamically detect and manage communication links; the communication-driven dynamic library is in When the communication is activated, the data router automatically loads the communication driver; each of the nodes corresponds to a communication device, and each of the nodes uses the configuration elements AI and AO as an interface for data interaction with the communication device; and Each node is equipped with a computing engine, which is used to run the communication logic edited by the user using the configuration form, and write the result generated by the operation into the corresponding shared memory of the node for other nodes to call.

Description

technical field [0001] The invention relates to a general data router and a communication method thereof, belonging to the technical field of industrial automation control. Background technique [0002] With the rapid development of information science and technology, sensor technology and Internet of Things technology have also made rapid progress. Under the current requirements of equipment joint control and smart factories, the information interaction between PLC, upper computer, sensors and other smart devices has become particularly important. Nowadays, all countries are trying to build their own Internet of Things. Through various information sensing devices, they can collect in real time any required information such as objects or processes that need to be monitored, connected, and interacted, and form a huge network combined with the Internet. Its purpose is to realize the connection between things and things, things and people, and all things and networks, so as to...

Problems solved by technology

[0003] However, the current communication protocols used by information sensing devices produced by different manufacturers are usually different, and the variety of communication protocols also leads to the diversification of communication drivers.

At the same time, the vast majority of communication drivers are in a black box state. It is difficult for users to re-develop communication drivers for a single hardware device, and the workload is heavy.

This brings great inconvenience for users to collect data information between multiple heterogeneous devices at the same time, and creates great resistance to the promotion of the Internet of Things
