Mobile Computing and Data Collection in Digital Forklift Systems

As warehouse intelligence continues to advance, the automation and informatization levels of forklifts in warehouses have also been significantly enhanced. In the past, warehouse management relied on manual retrieval and paper-based record verification to collect data, which was prone to human errors, reduced efficiency, and could not achieve real-time monitoring and data analysis. The new-generation intelligent warehouse logistics can be assisted by various technologies, including vehicle-mounted computer computing, wireless transmission, cloud services, RFID, UWB positioning, and sensors. Through the deployment of barcode scanners and handheld devices, it realizes real-time data collection and command delivery, thereby accelerating the flow of goods in a flexible operating mode. This provides more accurate and real-time data support for warehouse management.

Data collection within the warehouse is essential. Rugged tablet PCs come with touchscreen input, similar to all-in-one vehicle computers. Nevertheless, the more prevalent input devices are barcode scanners and RFID readers.

In warehouse, the management center sends instructions to the forklift mounted computer via a wireless network, directing the driver to relocate goods to the designated location. The driver uses a barcode scanner to scan and identify each piece of goods and then sends the goods’ information and operation results back to the backend system.

When handling large quantities of goods with a broader reading range, the RFID reader proves advantageous for rapid data collection and tracking, as it does not require individual contact or precise scanning. This is done by installing an RFID detection antenna on the front fork, scanning the RFID tags on multiple goods at once and then transmitting the collected data to the RFID reader. Finally, the data is inputted to the vehicle mount computer through wired or wireless means, thus completing the automatic identification of goods. This data can be sent back to the backend server at any time.
