Automatic load identification with the Automated Load Detect Ident System (ALDIS) from SICK enables transparent monitoring of loading and unloading processes. The advantages of camera-based systems, such as high read rates and precision even under difficult conditions, help to optimize logistics processes.
The challenge: Manual data entry and error-prone processes
Identifying goods in the warehouse is a key challenge in logistics and is often still done manually. Data must be entered manually and goods recorded with a small hand-held scanner. This is time-consuming and error-prone, resulting in inefficient workflows.
Another challenge is the reliable tracking of loading and unloading processes. The precise localization and identification of loads during transport and storage processes is crucial for their efficiency. The automation and digitalization of these processes are therefore necessary.
The identification technologies used must be able to reliably recognize different types of loads under changing conditions. In addition, the various systems and devices must communicate with each other and exchange data in real time. This requires a robust network architecture and modern software solutions.
The solution: Automated detection and tracking with ALDIS
The Automated Load Detect Ident System (ALDIS) from SICK is a complete solution for automating the identification and tracking of goods in logistics. ALDIS integrates various technologies to ensure reliable and efficient detection and identification of loads. The load is automatically detected by distance sensors and identified using technologies such as RFID, laser and camera. These variants can be selected depending on requirements and ambient conditions.
How ALDIS works in the warehouse
The central element of ALDIS is the Telematic Data Collector (TDC), which controls all sensors and processes the recorded data. The TDC communicates with the sensors and ensures transparent and accurate recording of the loading and unloading processes in real time. The data is transmitted wirelessly via mobile networks or WLAN to the software infrastructure, where it is processed and analyzed. The systems are configured via a browser-based user interface, which enables simple operation and full control over the data. ALDIS offers flexible integration into existing vehicle fleets of forklift trucks, regardless of the manufacturer and year of manufacture of the vehicles. Retrofitting is simple and straightforward, so that existing fleets can be digitalized and automated. The position data of the vehicles and loads are recorded outdoors via GPS and indoors via UWB (ultra-wideband).
These technologies enable precise localization of vehicles and loads. This makes it possible to see where the material, the pallet and the forklift truck are located at all times. The position data is linked to the identification data so that there is complete transparency about the movements and positions of the load.
Various ALDIS system variants offer customized solutions for different requirements. RFID technology makes it possible to identify the load without visual contact with the transponder and is particularly suitable for harsh industrial environments. Laser scanners are a cost-effective solution with a long range and fast autofocus, while camera-based code readers offer many other advantages that make them an indispensable technology in modern logistics solutions.
Advantages of cameras
The cameras offer high reading speed and accuracy. They can reliably read 1D and 2D codes (barcodes and data matrix codes) even under difficult conditions. A decisive advantage of camera-based systems is their ability to detect even heavily damaged or smudged codes. Other technologies have higher error rates here.
Another advantage is the flexibility and adaptability of the cameras. A large field of view and depth of field allow codes to be read from different angles and distances. This flexibility is particularly useful in dynamic environments where the position and orientation of the load changes frequently.
They are also suitable for scanning codes on moving objects. This is particularly advantageous in busy logistics centers where loads are constantly moving. A fast autofocus ensures that the codes are captured even at high speeds.
The cameras can be seamlessly integrated into ALDIS. They have advanced image processing algorithms that enable the images captured to be analyzed quickly and accurately. The codes are recorded and the information processed in real time. The data is then transmitted to the central software infrastructure via the Telematic Data Collector. Communication takes place via WLAN or mobile networks to enable flexible and location-independent use.
The result: Improved efficiency and transparency in logistics
The use of SICKS’ ALDIS significantly improves the efficiency and transparency of logistics processes. The digitalization of loading and unloading processes enables precise tracking of loads in real time, which reduces search times and increases process reliability. This creates a database for tracking and tracing loads. It can be analyzed in the Asset Analytics software solution and linked to the position data of the vehicles. This provides a complete picture of the location and status of the loads at all times.
