Problems solved by technology

[0002] The PLC control system and related control technologies have been relatively mature after years of development in the industry. However, there are many types of software for the PLC system. If a single software is used for control, it is difficult for the PLC system to be flexibly defined by software according to application requirements. To adapt to the hardware environment of different models, for example: the number and types of ports between different models, etc.
Under the existing method, it is necessary to continuously develop differentiated software to realize the above solution, but it greatly increases the difficulty of development, and the development cycle is long, and the stability and consistency of the software become poor.

Abstract

A software definition type control system comprises a platform layer and a terminal layer. The platform layer comprises a PLC program editing module, a variable management module, a hardware configuration module and an interface configuration module. The terminal layer is a PLC-series hardware. The platform layer comprises a core processing unit, an input-output module connected with the core processing unit, a communication module, a man-machine interaction module and a power supply management module. In the core processing unit, reconfigurable and transplantable PLC operating system core software can be utilized to form PLC operating systems of different types of CPU. The software definition type control system integrates a 'quick hardware resource establishment' technology, an 'interface configuration' technology and an Internet-of-Things technology are integrated, and for 'quick hardware resource establishment', a controller meeting interface requirements is established through quick software definition according to the demand. For the 'interface configuration', a special monitoring human-computer interface is customized according to actual application requirements, and the connecting relation between an interface control and a hardware interface is defined.

Description

technical field [0001] The invention relates to a software-defined control system and a control method, belonging to the technical field of software-defined interconnection. Background technique [0002] The PLC control system and related control technologies have been relatively mature after years of development in the industry. However, there are many types of software for the PLC system. If a single software is used for control, it is difficult for the PLC system to be flexibly defined by software according to application requirements. To adapt to the hardware environment of different models, for example: the number and types of ports between different models. Under the existing method, it is necessary to continuously develop differentiated software to realize the above solution, but this greatly increases the difficulty of development, and the development cycle is long, and the stability and consistency of the software become poor. [0003] Therefore, in this technical ...
