With the improvement of people is living standards and the increasing demand for high-end food, the whole society began to pay attention to food safety. China is food cold chain logistics has witnessed rapid development. At the same time, the traditional normal temperature logistics competition is very fierce, and the profit margin drops sharply, which makes the cold chain logistics field more and more become the hot spot of enterprises. As an important infrastructure of cold chain logistics, with market stimulation and policy support, refrigeration projects are emerging all over the country, but high-standard refrigeration resources are still scarce.

Automated three-dimensional cold storage takes "high efficiency, energy saving, intelligence, environmental protection, fully meet the personalized needs of logistics enterprises" as the project design concept. It adopts automatic logistics equipment such as stacker, WMS system, warehousing system, monitoring system, and uses RFID and bar code technology, which greatly improves the operation efficiency and achieves goods. "First in first out" and selective transportation to ensure the quality of goods stored.
Using WCS, WMS, TMS, OMS and other information management systems, the automatic three-dimensional cold storage can greatly improve the operation efficiency of the cold storage, which is 2 3 times that of the traditional cold storage.
In the intelligent identification of commodities, hand-held laser scanner (PDA), infrared sensor, GPS and other system equipment are used to locate, track, monitor and manage the commodities in refrigerated storage in real time. In addition, the Internet of Things technology is used to realize real-time sharing and docking between upstream and downstream enterprises.
Automated three-dimensional cold storage adopts professional cold chain logistics management technology to ensure the accuracy and operability of product information. The comprehensive information of cold chain projects can be inquired online, and customers can provide traceable services in the whole supply chain of commissioned projects.
Advantages of Automated Stereo Refrigeration Storage in Refrigeration System:
1) High degree of automation. The system is fully automatic and highly automated. It does not need manual operation during normal operation. When manual operation is needed, only commands are issued to the system, and the system automatically executes the contents of the commands, thus eliminating the hidden safety hazards caused by manual operation errors.
2) Establish customer and product information according to different customers. Each customer has a separate file in the WMS system. The system administrator establishes the receiving list in WMS system according to the customer is delivery order, product name, batch number, quantity, specification, etc. At this time, the relevant information is automatically transmitted to the PDA handheld computer, and the tally is delivered by the customer. The new document information is re-checked in PDA, then the tray number is scanned according to the actual cargo, and the tray is placed on the conveyor belt by forklift truck, then it is automatically put into the warehouse. After storage, the stacker sends the paper tray to the storage location according to the system instructions. After the completion of warehousing, the position information, pallet number information and goods information of the binder will be used as the operation voucher of the inventory information system.
3) Storage is selected according to product characteristics and stored in different product partitions. Storage products can be stored in isolation. According to different product characteristics and customer requirements, WMS system divides the storage status of products into qualified products. Unqualified products to be inspected. Inventory products can be inquired through relevant information (such as product specifications, batches, suppliers) to monitor the whole warehousing process.
4) The system administrator establishes the delivery order according to the customer is order, and sets it in the system according to the customer is personal needs. The system can execute "first in, first out" or selective batches of products.
5) After the document selection is completed, the system administrator clicks on the warehouse. At this point, the stacker will automatically search out the location of the warehouse product and leave the warehouse according to the document information. The tallying operation is arranged according to the display screen at the port of shipment. The system publishes work credentials.
