Use cases

Our edge, on-premises & cloud low-code software solution da³vid is used by customers from various industries as:

Below are some selected application examples:

Intelligent building technology: domestic hot water (DHW) heating

Problem: High costs and time required for commissioning and maintenance. Ensuring compliance with health and environmental regulations. Development of a new generation of devices with the functions required by end customers. Consideration of a multi-stage distribution channel (manufacturer → wholesaler → installer → end customer).

Solution: Local real-time collection of data from existing systems. Alerts are issued when problems occur. Remote maintenance and historical data enable cost-effective maintenance and sustainable optimization of the system. One hardware, different function levels: Customers can also unlock certain functions after installation.

Results: Reduced maintenance costs and enormous energy savings through system optimization directly from the manufacturer with consistent compliance with all requirements and operator obligations. Expansion of the business model and development of new sales potential.

Gearbox

Condition monitoring and predictive maintenance: industrial gearboxes

Problem: Vibration monitoring with a high sampling rate (several kHz) is to be used to monitor industrial gearboxes. The many gigabytes of raw data cannot be sent directly to the cloud via the LTE data connection. Therefore, important KPIs (“health” of the gearbox) must be calculated from the high-frequency measurements and sent to a cloud platform. Time2Market in 6 months from the start of development.

Solution: Use of an edge software platform for the basics and individual implementation of the high-frequency sensor connection. Calculation of KPIs via low-code scripting so that the formulas can be adapted by the customer at any time. Connection to the Azure cloud of a partner via MQTT.

Results: Compliance with the required Time2Market from the start of development and product launch by the customer within one year of the initial product idea in the group company.

System monitoring: Railway technology

Problem: The operators of railroad technology systems in Germany and other European countries require railroad technology manufacturers to integrate them into higher-level control systems and provide detailed information about the systems, e.g. via OPC-UA or MQTT. In addition, extended real-time visualization and parameterization options are required at various levels. Historical systems are often microcontroller-based and therefore cannot meet the requirements.

Solution: Use of an edge software platform for the basics and individual implementation of required protocols or special visualizations. Calculation of KPIs via low-code scripting so that the formulas can be adapted by the customer at any time Integration of a full OPC UA server directly on the edge gateway.

Results: Fulfilling the increasing requirements and enabling new innovative solutions. Thus significantly increasing the competitiveness of our customer.

Individual edge gateway

Problem: A Linux-based edge hardware (gateway) must be developed for a new product due to the performance requirements. Measured values must at least be stored locally and preferably also visualized. Software development from scratch consumes a lot of time for basics and cannot be planned. Additional topics such as cybersecurity are almost impossible to master.

Solution: Use a software platform that already includes all the basics such as data sources, database, data model editor, alarms and visualization - including cybersecurity. Use of in-house development capacities for the real individual core topics such as evaluation algorithms or planning of the data model. Support in hardware selection and flexibility through hardware independence: prototype with generic hardware, the series then developed customer-specifically by one of our hardware partners.

Results: Time2Market reduced by 6 months (often 50%) with 6-digit cost savings compared to in-house development. Significantly reduced project risk, as the basic functions are ready2use from day 1.

Production optimization (OEE)

Problem: The early meeting in production is still based on manual Excel evaluations. Performance (throughput, product quality, OEE) should be increased while reducing operating costs at the same time.

Solution: Connection of the machine controls (PLC) via the OPC-UA protocol and thus implementation of a real-time PDA (production data acquisition). Visualization of system statuses and shift performance in configurable dashboards.

Results: Significant simplification of early meetings, reduction of production downtimes, consistent measurement and increase in OEE.
