Description

Independent sealing air-conditioning control system and method for single storage roadway based on dense storage system Technical Field The invention belongs to the technical field of warehouse logistics, and particularly relates to an independent sealing air-conditioning control system and method for a single storage roadway based on a dense storage system. Background With the development of modern logistics and warehousing technologies, dense storage technologies are widely used due to the fact that the dense storage technologies realize high-capacity storage in a limited space, such AS automated stereoscopic warehouse (AS/RS), shuttle shelf systems and the like. However, in certain specific industrial applications, such as food (especially perishable foods, high-end agricultural products), pharmaceuticals, tobacco, precision instruments, cultural relics, and the like, where there are stringent requirements for temperature and humidity, gas composition (e.g., oxygen, carbon dioxide, ethylene, and the like) of the storage environment, conventional dense storage systems have difficulty meeting their long-term, stable, precise environmental control requirements. In the prior art, in order to realize air-conditioning storage, an air-conditioning mode is generally adopted for the whole warehouse or a large area. This approach suffers from the following disadvantages: 1. the energy consumption is huge, the atmosphere adjustment in the large space needs to consume a large amount of energy to maintain the gas concentration and the temperature and the humidity in the whole space, and the operation cost is high. 2. The regulation and control precision is low, the gas mixing in a large space is uneven, the temperature and humidity fluctuation is large, and the precise environmental control of specific objects is difficult to realize. 3. The flexibility is poor, different air conditioning parameters may be required for different articles, and the large-space unified regulation and control cannot meet the differentiation requirement. 4. The space layout and sealing requirements of the traditional air conditioning warehouse can conflict with high-density and high-efficiency access operation of the dense storage, thereby affecting the operation efficiency or increasing the reconstruction cost. 5. While environmental control is considered in part of the existing dense storage systems, most of the existing dense storage systems are simple temperature and humidity control, lack accurate adjustment capability for specific gas components, and do not realize independent sealing and air adjustment of a single roadway. Therefore, how to design a system which can be efficiently compatible with a dense storage system and realize independent sealing and accurate air-conditioning regulation and control on a single storage roadway, so that the energy consumption is reduced, the regulation and control precision and flexibility are improved, and meanwhile, the efficient operation of dense storage can be ensured, so that the system is a technical problem to be solved currently.
