Web and mobile Platform
Global Service is a web and mobile platform that plays a crucial role within STEM‘s business, serving as the common denominator between the company, its customers, and the entire commercial and distribution network.
STEM is a market leader in stretcher supports and retractable steps for professional vehicles.
It designs and produces cutting-edge devices for the safety and outfitting of ambulances. Over time, it has gained worldwide credibility and recognition thanks to the high quality and efficiency of its products, which are increasingly oriented towards automation and technological innovation.
Developed projects
Global Service is used as a management and remote management system for STEM articles, connecting via Bluetooth or Internet through the MQTT protocol. The system thus allows for remote firmware updates of the devices, sending remote commands, and reading diagnostic data.
In this regard, significant analytical work has been carried out, leading to the design and implementation of a proprietary communication protocol. This protocol enables the interconnection of STEM products, even of different types, using a common and shared methodology. This allows for the use of heterogeneous technologies such as Bluetooth Low Energy and GSM while maintaining a uniform data structure.
The collected informations are sent to the server, where the system is integrated with Azure’s IoT HUB service via the mobile application or directly through GSM. Here, the informations are stored, processed, and then analyzed to be summarized in dashboards that highlight the relevant KPIs, allowing the execution Business Intelligence operations, predictive maintenance, device health checks, and more.
Integrations
Furthermore, Global Service is a platform capable of providing numerous centralized services for the distribution network and the end customer. Thanks to the integration with the company’s SAP management system, the system can control all aspects of the lifecycle of the developed and marketed products, from testing at the company, through sales, delivery, and post-sales support.
Through Global Service, STEM manages:
- User authentication and configuration of related grants
- User licences
- Training in the use of devices and manuals
- Help-desk and support tickets
- Survey and scanning of item codes and serial numbers;
- Maintenance interventions
- Product Warranty
- Reporting and documentation
- Data analysis and statistics
- Spare parts
User Management
Global Service is essential for STEM‘s operations in all the countries where the company operates, acting as a link to the external world. It serves as a single, clear, and shared reference point for internal operators, as well as for partners, stakeholders, and end customers.
Through the hierarchical management of registered users and the grants provided to them, STEM can securely control its sold product fleet and determine who can operate specific devices, which are enabled only after participating in the relevant training courses. This maintains a high degree of security and competence in the management of its articles worldwide.
