General data router and communication method thereof

Abstract

The invention provides a general data router and a communication method thereof. A dynamic communication driver library and multiple nodes are configured in the general data router, and communication links are dynamically detected and managed by adopting the mode of a thread pool; the dynamic communication driver library allows the data router to automatically load a communication driver when communication is activated; each node corresponds to one communication device and utilizes configuration elements AI and AO to serve as interfaces for achieving data interaction with the communication device; and a computing engine is configured for each node and used for operating communication logic edited by a user in a configuration form and writing a result generated in operation into a shared memory corresponding to the node to allow the other nodes to call the result.

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
