Intelligent controller system for large engineering equipment

Abstract

The invention discloses an intelligent controller system for large engineering equipment. The intelligent controller system comprises a mainboard, a signal acquisition unit and a self-adaptive PLC communication module. A CPU which is based on an embedded parallel processing framework is arranged on the mainboard. The mainboard is connected with a sensor or an instrument in the large engineering equipment through the signal acquisition unit, acquires equipment operating state signals or detection data detected and output by the sensor or the instrument, outputs a control instruction to a controlled device in the large engineering equipment, and controls the controlled device to operate automatically. The mainboard is connected and in communication with a PLC in peripheral equipment through the self-adaptive PLC communication module, forms an internet of things, conducts configuration monitoring on the PLC, and synchronously backups all data in peripheral controllers in the internet of things by means of a distributed data storage technology. The intelligent controller system for the large engineering equipment has the advantages of being high in system data processing speed, high in system operational stability, safe, and high in efficiency, and lowering the difficulty in system design, development and maintenance at a later period.

Description

technical field [0001] The invention belongs to the technical field of engineering equipment, and in particular relates to the design of an intelligent controller system suitable for large-scale engineering equipment. Background technique [0002] The so-called large-scale engineering equipment generally refers to engineering equipment with large scale, many factors involved, and far-reaching influence, such as mining, oil and gas field development equipment, construction engineering equipment, water conservancy engineering equipment, iron and steel smelting equipment, chemical processing equipment, etc. In today's large-scale engineering equipment, most of the central controllers used are programmable logic controllers, that is, PLCs, and their shortcomings are mainly reflected in the following three aspects: [0003] First, the operating environment of large-scale engineering equipment is complex, and usually needs to be used in conjunction with many peripheral devices. Th...

Problems solved by technology

This way of working determines that when the PLC executes the program, the instructions must be short and concise, so that all instructions can be executed in the shortest possible scan cycle, otherwise the longer the scan cycle, the more serious the lagging phenomenon, and it can only be processed serially and cannot be processed in parallel. instruction

This limits the control realization of PLC, making it impossible to realize complex control algorithms and control functions
