Control program organization structure of control system and download method

Abstract

The invention relates to the technical field of an industrial control system and particularly relates to a control program organization structure of the control system and a download method. The control system comprises a controller and configuration software, wherein the controller is internally provided with an operation management core in a solidification mode, a background system of the configuration software is stored with a program module database, the program module database is stored in the configuration software in an encrypted linkable file mode, the foreground of the configuration software realizes programming and download of user configuration programs carried out by users, the operation management core, the program module database, the user configuration programs and data sets form a control program, and communication and interaction of the control program between the controller and the configuration software is carried out through a download interface. The control system is advantaged in that the control program module database is stored in the background of the configuration software, control program modules actually utilized by the configuration program are downloaded to store in the controller only after download, not only can the program structure of the controller is simplified, program scheduling and management are made to realize more rapid and reliable, but also storage resource pressure of the controller is further reduced.

Description

technical field [0001] The invention relates to the technical field of industrial control systems, in particular to a control program organization structure and download method of the control system. Background technique [0002] With the development of automatic control technology, control systems have been more and more used in various industries, and the technical requirements are also very different due to different market segments. While the scale of control systems (such as DCS) in the field of process control is getting larger and larger, small or micro controllers such as micro-PLC are also being used in more and more applications in processing and manufacturing, vehicle control, robots, etc., and There is a trend of further miniaturization and integration. For example, the industry already has an on-chip control module chip (CMC chip) that integrates control functions, control algorithms, and industrial communications on a single chip. [0003] Although the scale ...

Problems solved by technology

However, for microcontrollers or CMC control chips with very limited memory resources for cost advantage, too many idle program modules may cause loss of other functions of the controller or limited performance

[0006] On the other hand, the way that the traditional control system solidifies all the program module libraries in the controller makes updating the program module library necessarily require arriving at the industrial site to update the controller's firmware as a whole, which is very important for the version maintenance of the controller and the user group. ecological engineering protection is detrimental

According to various industrial site environments, security levels and equipment embedded designs, it is difficult to implement the upgrade of this program module library
