Technical Field

[0001] The invention belongs to the technical field of warehouse storage and retrieval, and in particular relates to an inert gas intelligent warehouse. Background Art

[0002] With the rapid development of science and technology, more and more high-precision devices have emerged, which are widely used in semiconductors, microelectronics, precision instrument manufacturing and biotechnology. However, high-precision devices are easily corroded or oxidized by moisture and oxygen in the air during storage. Therefore, the storage of high-precision devices requires an oxygen-free storage environment, which is often difficult to meet in traditional storage warehouses. In recent years, the rise of smart warehouse technology has provided a new idea for solving this problem. Smart warehouses use advanced technology to fill the warehouse with sufficient nitrogen to maintain constant temperature, humidity and pressure in the warehouse. Through the automatic control system, accurate control and real-time monitoring of warehouse environmental parameters are achieved, providing more reliable protection for the storage of high-precision devices.

[0003] However, in the actual application of smart warehouses, especially during the storage and retrieval of goods, nitrogen leakage is prone to occur. At the same time, as the number of storage and retrieval times increases, the outside air will gradually penetrate into the shelves, reducing the purity of the nitrogen in the shelves.
