A method for realizing efficient real-time interaction between application layer system and basic automation

Abstract

The invention relates to a method for realizing highly efficient real-time interaction between an application level system and basic automation, which belongs to the technical field of metallurgical automatic control. According to the technical scheme, an interaction apparatus (1) and a programmable logic controller (PLC) (5) are arranged to be in the same network segment of Ethernet Two (8) and can communicate with each other; the interaction apparatus (1), a rolling parameter model system (2), a manufacture execution system (MES) (3) and an energy control system (4) are arranged to be in the same network segment of Ethernet One (7) and can communicate with each other; a data decoding program is responsible for converting low-level data stream into high-level data or converting high-level data into low-level data stream; and a communication program is responsible for transferring the data decoded by the data decoding program to an upper-level program or a basic automation PLC. The method realizes effective interaction between the basic automation and the upper-level application system data, solves a problem of data delay due to over-quick production pace, and makes a breakthrough in solving the problem that process parameter storage cannot be performed due to the hardware condition of the basic automation.

Description

technical field [0001] The invention relates to a method for realizing high-efficiency real-time interaction between the application layer system and basic automation, which is used to quickly and accurately transfer the rolling parameters in the application layer system to the PLC, and at the same time collect the rolling process parameters for analysis of other application layer systems The invention belongs to the technical field of metallurgical automatic control. Background technique [0002] In the production of large-scale section steel in the metallurgical industry, section steel wire has the characteristics of many types of production, many production rolling schedules, and fast production rhythm. First, every time a type to be rolled is replaced, the operator needs to The system parameters are entered through the WINCC screen and then transmitted to the PLC, which brings great inconvenience to the operators and cannot guarantee the production efficiency in the roll...
