Automated high-bay warehouses with stacker cranes are a central element of modern intralogistics. They enable quick storage and retrieval and make optimal use of the warehouse area. When installed in deep-freeze storage facilities, their components must withstand the special requirements of the –30°C refrigeration temperature. The uninterrupted cold chain must be guaranteed throughout the movement of goods stored there.
The industrial event camera is mounted directly on the stacker crane and monitors the storage and retrieval processes. The camera continuously records the last 60 seconds of the continuous video livestream in its integrated circular buffer. Faults or defined events in the sequence act as triggers for the camera to transfer cached data to permanent storage on an SD card. All recordings last for up to 60 seconds before and after the event. This enables them to be used to identify the cause of the event and the state that subsequently occurred. Only relevant situations are recorded. The image sequences can be used for immediate fault analysis or long-term process optimization.
Unlike a continuous video sequence, event-oriented storage not only handles data streams economically, but also allows direct access to recordings of the relevant situations. The date, time, and error message are displayed in the text overlay of the recording. A digital hardware input can record trigger signals that come directly from the control system or a trigger sensor.
The password-protected user interface can be displayed on any web browser. It provides a live image in HD quality and enables the device to be easily configured. Additional PC hardware for integration and storage is not required. The REST API can also be used to program an individual user interface and directly integrate the device into the IT system. An integrated heating system is available for use in cold storage and outdoor areas, meaning the operating temperature ranges from –30° C to +50° C. The camera’s IP65 degree of protection makes it impermeable to dust and water jets.
