Modeling method for smart factory

Abstract

The invention relates to a modeling method for a smart factory. Data mapping is carried out on each device and a database of a background control center; data synchronization between the background control center and the devices is realized; data of the background control center is displayed in a visual interface of a computer; an operator can control operation tasks of the devices by modifying the data in the interface; editing conditions of a control program of each device are recorded in real time, and tracking and recording of device operation tasks can be realized; the operator can conveniently control the devices; classification is carried out according to the type of a control system in device information; different control systems of devices of different manufacturers can realize interconnection and intercommunication with the background control center; in the process of managing and controlling the devices, control programs of the devices in the background control center are modified and maintained through a visual interface of a computer, so that remote scheduling of actual production devices is realized, and the scheduling process is carried out in real time.

Description

technical field [0001] The invention belongs to the technical field of industrial production control, in particular to a modeling method for smart factories. Background technique [0002] With the development of information technology, more and more data are stored electronically to improve the convenience and efficiency of data storage, and at the same time, later analysis can be performed based on these data. At present, most control systems use DDE technology or dynamic link library technology for data exchange. When the communication volume is large, there will be limitations such as slow data transmission speed, poor security, and low reliability, and it cannot be integrated with the upper management system. [0003] In the Chinese invention patent with the announcement number "CN108388223A" and the title "A data-based closed-loop equipment control system for smart factories", a data-based closed-loop equipment control system for smart factories is disclosed. The syste...

Problems solved by technology

[0004] In the above patents, the OPC specification is used to simplify the complexity of the system and shorten the development cycle of the system. However, in practical applications, the equipment produced by each manufacturer may be equipped with different control systems. In this case, how to integrate different control systems It is a problem that needs to be solved urgently in the current system model
