SCHADE PREMAS 4.0 / Predictive Maintenance for Conveyor Systems
We have developed a software for preventive and predictive maintenance of longitudinal and circular storage machines of SCHADE Lagertechnik GmbH. The user interface design is designed for customer service technicians and provides an overview of all important production parameters that can be monitored to prevent breakdowns and unforeseen faults.
The interface focuses on the key figures relevant to maintenance. Therefore, our focus was on designing them clearly and visualising them vividly with the help of individual infographics. The user interface is grouped into dashboards that are thematically assigned to machine modules and specific monitoring topics. The dashboards provide the user with a quick overview of the respective topic and serve as an intuitive entry point to the detailed pages of the software. Here, the key figures can be analysed over time with detailed trend displays. Each detail page also offers contextual help texts on the respective topic.
User interface design
The graphic design is derived from the corporate design of the manufacturer and the associated group of companies and, with its restrained colours, offers an ideal platform for warnings and error messages that attract the operator's attention with signal colours. In this way, potential faults can be quickly localised and remedied at an early stage before the entire system breaks down. An integrated message history also offers the possibility of tracking warnings and faults in an organised manner.
We designed the user interface primarily for use on mobile devices. Thanks to the responsive design, the software automatically adapts to common device sizes and can be operated both on a smartphone and on the PC workstation of a control centre.
HMI Management with Helio
The frontend was implemented using web technology and based on our HMI management system Helio. Using the Helio Content Editor, the entire frontend is configurable in terms of content and can be adapted to new machine types and applications. During project planning, the application engineer uses ready-made page and widget templates to create new dashboard configurations. The layout of the dashboard adapts to the number of widgets used. Depending on the selected layout, content in the widgets is faded in or out to ensure consistent readability. Helio does all this automatically, without any additional effort on the part of the user. The data points are connected to the PLC via a standardised OPC-UA interface and can be easily linked via the Helio Content Editor.
Storage and conveying
The context of the project is mechanical and plant engineering in the field of materials handling technology and related areas. The software is used for bulk material storage areas and blending beds for all industries, which are used in the cement, iron, steel and aluminium industries, in the power plant industry, in the mining & minerals sector, for alternative fuels as well as in ports and terminals.
