The wireless-based communication network nexy brings order and transparency to dolly fleet management. Typical uses include the supply of automotive production halls from "supermarkets" and FIFO stations, as well as the management of empty containers.
The nexy system detects a dolly, e.g. when it drives onto a monorail track, and sends a corresponding notification via an Access Point to the central control system for material flow and replenishments. The containers and large load carriers transported by the dollies can also be detected – if so desired. This task can be assumed by laser sensors in different variants, for example, but also by sensors which detect the presence of boxes on the individual shelves of eKanban racks. They, too, of course, communicate by remote control. And many users deploy these sensors in combination with stack lights, which can also be integrated in the nexy wireless system.
The preconfigured dolly application from nexy has now been expanded to include new functions. The logic has been trained to achieve a detection precision of almost 100%, independently of any operational errors or imprecisions – for example, if a dolly cannot fully drive over the sensor at the start of the monorail track because the track is already full. The nexy system will also send a notification if a dolly in a FIFO station is removed from "the wrong end", i.e. where the dollies enter and not where they leave.
The new functions have been realised from a precise observation of nexy applications in practice. In existing installations they can simply be installed with the next update, and be configured and visualised via the Sensor Bridge web interfaces of the nexy wireless network.
