Shunde Xingang Phase II intelligent coil steel warehouse started in September 2023, covering an area of 28,700 square meters, the construction of two four-span finished product workshops, dedicated to cold coil storage. The warehouse is highly intelligent and unmanned, with an effective storage area of 23,300 square meters and an expected annual turnover of 1.8 million tons, which will be put into use in September 2024.

Warehouse equipment
Warehouse equipment includes 8 automatic cranes, lifting 35 tons, lifting speed of 15 m/min, car speed of 65 m/min, truck speed of 120 m/min; The gauge is 23.2 meters. Storage capacity is: single layer 4 to 70,000 tons, double layer 7 to 120,000 tons.

Reservoir characteristics
Horizontal and longitudinal overlapping, flexible spacing
The smart coil steel warehouse of Shunde Xingang Phase II adopts the innovative small wave saddle storage form, breaks the traditional fixed spacing limit, and realizes the optimization of storage mode and the significant improvement of space utilization. The online operation of the intelligent storage system WMS promotes the efficient linkage between the reservoir area, the terminal and the vehicle, optimizes the command scheduling model, and greatly improves the logistics efficiency.

Multi-vehicle linkage, task coordination
With the operation of intelligent coil steel warehouse as a highlight, Shunde New Port Phase II successfully broke through the traditional fixed spacing stacking mode, adopted the innovative small wave saddle stacking form, and achieved a significant improvement in the utilization rate of warehouse space. The online operation of the core intelligent storage system WMS has promoted the efficient linkage between the reservoir area, the terminal and the vehicle, optimized the command scheduling model, greatly improved the logistics efficiency, and strengthened the close cooperation between the warehouse, the storage yard and the shorelines, marking the solid step taken by Shunde New Port in the intelligent logistics management, showing the new style of China's port logistics modernization.

Intelligent loading, flexible adaptation
The operation of intelligent coil steel warehouse breaks through the traditional fixed spacing stacking mode, and realizes the significant improvement of the utilization rate of warehouse space. Combined with the intelligent loading function, the WMS system can accurately manage the loading in and out of the warehouse according to customer requirements, cold-rolled products and transport vehicles. This intelligent process has significantly increased warehousing efficiency, reduced operating costs and significantly improved customer service levels.

Key technology
3D laser modeling technology
Using the principle of laser distance measurement, the 3D model of coil steel is reconstructed by scanning the surface of coil steel at high speed, and the inner and outer diameter information of coil steel is obtained quickly. The laser scanning equipment has the characteristics of non-contact, high precision and high efficiency, which can further improve the rationality and safety of cold roll storage.

Precise positioning technique
Using rotary encoder, non-contact electromagnetic induction, laser and other technologies. The anti-roll control technology is based on the anti-roll running algorithm of the single pendulum motion model to ensure that the running swing is less than 0.5°.

Multiple job protection technology
Based on diffuse laser ranging, weighing sensing and other technologies, multiple protection take-up and takedown process to avoid human and object damage.

Regional collision avoidance and traffic path optimization model
The safe and efficient operation is guaranteed by means of curve bypass and three-dimensional linkage control.

Library location optimization model
Through planning prediction and flexible warehouse location recommendation model, the maximum utilization of warehouse space is realized.

Cooperative scheduling model
Based on intelligent platform interconnection, big data analysis, reasonable allocation of resources, improve work efficiency.
