System and method of transmitting industrial data

Abstract

The invention provides a system and a method of transmitting industrial data. The system comprises a plurality of first objects, a statute gateway and a plurality of second objects, wherein each first object is respectively connected to the statute gateway and real-time communication can be synchronously carried out, the statute gateway is respectively connected to each second object and real-time communication can be synchronously carried out, each first object or each second object can be an instrument, single production equipment, a production equipment bus formed by a plurality of production equipment or a production system formed by a plurality of production equipment buses; the statute gateway comprises a distribution module, a first selection module, a data acquisition module, a second selection module, a data conversion module and a data transmission module.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to an industrial data transmission system and an industrial data transmission method. Background technique [0002] Each communication corresponds to a protocol for data transmission, also known as a protocol, and corresponds to a medium that carries this protocol. For example, opening a web page requires the support of the http protocol (Hypertext transfer protocol, hypertext transfer protocol), and the network cable is a transmission medium of the http protocol. [0003] In the industrial field, it is an inevitable development trend to combine small devices or systems into large systems for centralized control and unified scheduling. The smart devices used or the comprehensive automation control systems constructed by multiple smart devices basically use proprietary or partially public protocols, and these devices or systems are likely not to support the same protocol,...

[0003] In the industrial field, it is an inevitable development trend to combine small devices or systems into large systems for centralized control and unified scheduling. The smart devices used or the comprehensive automation control systems constructed by multiple smart devices basically use proprietary or partially public protocols, and these devices or systems are likely not to support the same protocol, or even support the same protocol, but the usable interface is limited or the scalability of the protocol can no longer be increased, etc., the corresponding transmission medium There are also various types, all of which are based on different protocols, limited interfaces, or insufficient protocol expansion capabilities to prevent data transmission, making cross-system data transmission in the industrial field difficult.

[0004] On the other hand, network conflicts may occur when individual devices or systems are assembled together. Since the IP addresses used by different devices or systems may be the same, these devices or systems cannot be distinguished and cannot exchange data with the outside world.
