China's logistics and storage costs have been high. The application of three-dimensional warehouse is not common, and the increasing labor cost and land cost lead to the high storage cost. Storage is an important part of logistics. In order to reduce the total cost of social logistics, the cost of storage must be effectively reduced. From the perspective of way selection, the task of automatic transformation of warehousing link is imminent.

The core problem to be solved by automatic storage system is how to accelerate the pace of goods access, reduce the labor intensity of workers and improve production efficiency.

The traditional storage system lacks the support of information technology, and manual operation is mainly used in the links such as loading and unloading, distribution, shelves and sorting, which is not only low efficiency, labor intensity, but also prone to mistakes. The emergence of information technology, especially the Internet of things technology, makes it possible to automate and intellectualize the storage system. For example, the use of sensors for automatic identification, the use of radio frequency technology for automatic information transmission, the use of robot system for goods sorting and handling, not only greatly reduced the labor intensity of workers, and efficiency and accuracy have been greatly improved.
