Cognitive-technology-based video data synthesis method

Abstract

The invention discloses a cognitive-technology-based video data synthesis method which belongs to the field of fault diagnosis systems of automatic systems. The method comprises the following steps of: (1) checking whether the line of a video monitoring system is normal or not; (2) carrying out data encryption and storing encrypted data into a data server of the video monitoring system; (3) implementing the positioning and the integration of video data and article electronic tag data; and (4) generating a text signal for specific characters requiring overlying in the video monitoring system by utilizing a corresponding relation of the video data and the article electronic tag data which are generated in the step (3) as well as temperature and humidity data, and meanwhile, finding the recorded text signal of the image in the data server of the video monitoring system; and comparing the two text signals. The method has the advantages of implementing the association of the video data and the data requiring overlaying, implementing data fake prevention, judging whether the line has unexpected cases or not and monitoring whether the work of monitoring flow operation staff is formal or not.

Description

Technical field [0001] The invention belongs to the field of fault diagnosis systems for automation systems, and particularly relates to a video data synthesis method based on signal detection technology. Background technique [0002] The basic principle of video overlay is to switch between the original video information and the overlay information by controlling the high-speed analog switch. According to the scanning timing of the TV system, the character dot matrix data is switched on the pixel point of the display character. In this way, it is realized on the video signal. Superimpose characters. The character dot matrix data is generated by the graphic dot matrix information sent to it by the single-chip microcomputer through the PC. The single-chip computer and the PC communicate through the serial port. With the support of the PC, the character content can be modified online and updated in real time, and the display content The position is controlled in real time. [0003]...

AI Technical Summary

Problems solved by technology

Especially in cold chain logistics safety supervision, video information is indispensable, but video information in various logistics links such as production, warehousing, transportation and sales is only used for safety monitoring, only receiving external data and real-time related information The ground and the image are displayed on the monitoring screen, and the identification of the item in the video information cannot be realized

[0008] (2) Information security issues

This method has the complexity of converting characters into pictures, and consumes CPU time slices and memory, which is inefficient and has no data anti-counterfeiting detection mechanism protection.
