Development of a Web Application with a Sheet Movement Visualization System for Tracking the Technological Process in a Sheet Rolling Shop

The article describes the technology of developing a web application for a sheet rolling shop mnemonic diagram with a sheet metal movement visualization system and an algorithm for processing information flows about their location. The relevance of creating a mnemonic diagram is substantiated. The need to increase transparency in the sheet metal tracking and accounting system through visualization is shown, which is due to the problem of controllability of production processes that lead to downtime on units and corresponding violations in the steel sheet control and accounting system. The web application is a Django application developed using the Redis noSQL DBMS. With the help of the developed algorithm consisting of a sheet movement tracking module and a web interface, developers have the opportunity to debug the application without having to install equipment at the stage of designing and testing the web application. The information flow tracking algorithm, file structure and web page of the application, and the structure of JSON data transmitted to Redis are presented. This approach allows increasing the transparency and efficiency of the 2800 mill, increasing the speed of decision-making on managing production operations in the shop within a shift.
