Output picture acquisition system and method of display screen of industrial control equipment

Abstract

The invention discloses an output picture acquisition system and method of a display screen of industrial control equipment. The system comprises an image acquisition unit for shooting a real-time picture of the display screen of the industrial control equipment to acquire image information; a template parameter processing unit for providing a recognition template, setting recognition template parameters and adjusting camera parameters; an image recognition unit for performing recognition on the image information according to the current recognition template, and outputting recognition resultdata; a recognition result processing unit for storing and / or uploading the recognition result data. The output picture acquisition system disclosed by the invention realizes the non-invasive data acquisition on the output picture of the display screen of the industrial control equipment without improving the existing production equipment and establishing the connection with the existing equipment; especially in the image recognition process, the image information is recognized according to the recognition template; not only is the recognition result accurate and reliable, but also is the system easy to arrange and low in cost.

Description

technical field [0001] The invention relates to an image data acquisition system in an industrial production process, in particular to a system and method for acquiring an output screen of an industrial control equipment display screen. Background technique [0002] With the development of modern industry, the market has higher and higher requirements for intelligent production equipment. For early production equipment such as EDM machine tools and wire cutting machine tools, most of these equipment still use the original control system. These hardware systems Basically, there is no interface to open to the outside world to obtain data in the production process, nor does it support existing extension protocols. If it is necessary to implement intelligent management such as data collection and working condition monitoring for such equipment, there is no other more effective method other than upgrading the software and hardware of the equipment. For example, upgrading the sof...

Problems solved by technology

For example, upgrading the software and hardware structure of production equipment can only be completed by relying on the original manufacturer of the equipment. At the same time, the production line needs to be redesigned and transformed. The cost is high and the pertinence of intelligent management is not strong, which is not conducive to The implementation of intelligent management of equipment, so there are many defects
