11„STILL NEXXT REAL TIME:CLOUD-BASED SERVICEThe STILL neXXt Real Time application, which is currently being tested as part of a pilot project, is STILL’s way of showing how much easier the service process can be for customers once connectivity is factored in. This is how the digital service process works in real time: If a forklift truck is found to have a defect, the operator uses the app on their smartphone to scan a QR code located on the truck. The damage is recorded in a digital conversation with a service bot (a virtual assistant). The app then sends all of the relevant data to the responsible STILL Service Coordinator, who in turn sends the data directly to the next available STILL service technician in the form of a push notification. This service technician then collects the right spare parts and makes their way to the customer, who can track the progress every step of the way in real time. TITLE STORYAnsgar Bergmann represents STILL on the IC4F flagship project funded by the BMWi. The acronym stands for Industrial Communicat-ion for Factories. As the name suggests, the main aim of the project is to develop secure and robust solutions for communicating in real time within the manufacturing industry. “What would be the ideal data infrastructure for companies and what would be the best way for us to fit into this infrastructure as the solutions provider so as to offer maximum benefit to the customer?” says Bergmann, summing up one of the key questions covered by this project. And in order to answer that question, big industry names such as Bosch, Siemens, Nokia, Telekom and STILL are joining forces with renowned research institutions like the Technical Universities of Berlin and Kaisers-lautern and two Fraunhofer Institutes to focus on one element of the project.5G: REAL-TIME COMMUNICATION“5G mobile network technology is crucial here,” says Bergmann. “It is the first ever technology to enables real-time communication without any restrictions caused by location or WiFi, and it drama-tically increases the number of objects that could potentially be interconnected.” Look at it this way: The current 4G technology allows for 1000 objects to be connected per square kilometre. With 5G, this figure shoots up to a million. This latest mobile network technology makes it possible to set up a secure company network across different locations as an enterprise cloud. “Basically, comp-anies can become their own provider with their own mobile network,” explains Bergmann. STILL has already partnered up with NOKIA to launch a private mobile network of this kind at the Robotics Centre in Hamburg.As part of the IC4F project, which is running until 2020, various use cases are currently being put into action with a view to turning the underlying theory into practical solutions. The aim is to clearly demonstrate the benefits of an open, real-time communication module. One of STILL’s four use cases is called ‘Truck to X’. Forklift trucks are being adapted so that they can communicate with other objects within a warehouse. Ansgar Bergmann provides a clear example of how relevant this is: “Up until now, switches or light barriers have mostly been used to open doors and gates. In the case of Truck to X, a forklift truck just tells the door or gate when it wants to pass through it. The door or gate is aware of the exact status of the truck as it has access to its digital twin. So if, for example, the mast has been extended so far that it will not fit through, the door or gate simply tells the truck that it needs to lower its mast before it will open. This is an effective way of avoiding accidents.”INTERCONNECTED FLEETSIt’s going to be a while before solutions of this calibre become reality. Having said that, though, it is already possible to access relevant truck data via a digital interface. It is exactly this feature that the online portal for optimising the STILL neXXt fleet makes use of, with forklift trucks that are fitted with GSM modules transmitting their data to a secure server via a mobile network. From there, the data is retrieved by the nine STILL neXXt fleet applications that are currently available on flexible subscriptions. The data can be accessed through a central user interface. This way, users can see where their forklift trucks are stationed, whether all their trucks have been loaded up evenly, when their trucks next need a service, how their trucks fared at their last inspection and much more – all at the click of a button. “Users can also access the system to get informa t-ion about certain events automatically. For example, they can check if self-imposed budgets for service or rental costs have been over-run,” explains Michael Manske, a Product Trainer at STILL. The fact that there are nine separate applications, each with a clear focus, is 5G5G is the latest in mobile network technology, allowing a million objects to communicate in real time in each square kilometre.
