AIC has initiated the use of unmanned drones with RFID technology for inventory management, resulting in an 80% reduction in labor costs. As a subsidiary of SAIC Group, SAIC Anji Logistics manages millions of vehicles transported by SAIC within China each year. Their warehouses must store data on the conditions, quantity, and locations of thousands of cars, and undergo regular inventory checks. Traditional inventory methods rely heavily on manual operations, which are not only time-consuming and labor-intensive but also prone to errors, making them inadequate for the fast-paced demands of the modern automotive manufacturing industry, significantly impacting logistics efficiency.
To address this pain point, SAIC Group actively explored and introduced a warehouse inventory solution utilizing unmanned drones and RFID technology from Beijing Xinlianchuang Company. This solution combines the high-altitude operation capabilities of unmanned drones with the precise identification capabilities of RFID technology, enabling automation and intelligence in inventory management.
Unmanned Drones and RFID: Efficient Coverage, Precise Identification
Unmanned drones play a vital role in inventory management. Equipped with high-precision RFID readers, they autonomously fly along preset flight paths, covering every corner of the warehouse. The high-altitude perspective and maneuverability of drones allow them to seamlessly navigate complex warehouse environments, scanning and identifying vehicles comprehensively. This process not only enhances inventory efficiency but also reduces potential safety hazards from manual entry into the warehouse.
RFID technology provides precise data support for inventory management. Each car is equipped with an RFID tag containing unique identification information and related data. As drones fly over the vehicles, RFID readers quickly read the information from the tags, transmitting the data to the backend system for processing. This process ensures real-time data updates and accurate record-keeping, guaranteeing the authenticity and reliability of inventory data.
The use of unmanned drones and RFID in inventory management has brought several enhancements to SAIC Group:
- Doubling Inventory Efficiency, Halving Time Consumption
Previously, manual inventory checks were arduous and time-consuming, requiring six employees to work continuously for half a day, collecting data, correcting errors, and uploading data within the warehouse. To ensure accurate data, vehicle flow in the garage was disrupted, causing almost a day of operational stagnation. Cumulatively, the days lost per year due to inventory checks were substantial. Now, the introduction of drone technology has completely transformed this situation. Drones can upload data instantly during flight, reducing inventory time by over half directly.
- Enhancing Inventory Precision
The traditional method of manually recording vehicle codes was not only inefficient but also had a high error rate. Prolonged copying work could lead to distraction and impact data accuracy. In contrast, the automatic data collection and transmission method of drones not only speeds up the process but also has an extremely low error rate, maintaining precision throughout. Moreover, combining GPS technology allows for rapid vehicle location during each inventory update, further enhancing management efficiency.
- Substantial Reduction in Labor Costs
Previously, six employees spent hours in a vast 5000-square-meter warehouse conducting inventory checks; now, a pre-set flight path and a simple button press enable drones to efficiently complete the task. For larger garages, only occasional drone battery replacements are needed for continuous operation. This transformation not only significantly saves on labor costs but also liberates employees from the tedious inventory tasks, allowing them to focus on more strategic and innovative work, creating greater value for the company.
