Currently there are tools that generate source code automatically. We propose a source code generation architecture focused on the 3-layer architecture, additionally we build a source code generation tool. The Tool allows to load a database schema and from this it generates the source code for the SQL Server and C# language, we use an .xls file to import or export the database schema. We have used 5 code generation requirements and their database schemas for the test, obtaining as a result the generation of source code without errors. Carrying out the time analysis, our model generates 6,998 lines of code per second, in total we have generated 13,283 lines of source code in 1472 milliseconds that correspond to 5 requirements for generating source code with their respective databases.

It is common knowledge that mechanical systems need oversight and maintenance procedures. There are numerous prevalent operation monitoring techniques, and in the era of IoT and predictive maintenance, it is possible to find multiple solutions to supervise these systems. This article describes the design and implementation of a low-cost system, which use an IoT approach to detect overheated idlers in conveyors belt in mining facilities. The system involves the use of temperature sensors, coordinately with heat map image sensors. The users (i.e., mining operators) can monitor overheated idlers in the whole conveyor belt, making on-demand queries using Telegram or a website, and also receiving autonomous warnings. Prototypes of this system were installed on a conveyor belt at a construction materials manufacturing company, and also in a copper mining company, both located in Apurimac, Peru...
