Production Workflow Monitoring

We have developed a software that monitors the workflow of the production and full assembly of all components. The system monitors where, when, by who and for how long the components were assembled and whether they were inspected or returned to the previous workplace for repair. The system uses sixteen PDA barcode readers in respective mobile phones with the Android operating system and four industrial screens that display the current status at individual workplaces. The mobile application was created on the Xamarin platform, the server uses .NET Core and the website was created in Vue.js. Communication takes place via GSM and SIM cards are located both in the PDA itself and in the Raspberry Pi modules. If the device loses internet connection, the data is stored locally and synchronized when the connection is re-established.
