One-button intelligent library management system

Abstract

The invention discloses a one-button intelligent library management system. The one-button intelligent library management system comprises a library body, a sensor used for detecting the oxygen, temperature and humidity in the library body, a programmable logic controller (PLC), a liquid nitrogen device, a control system and a touch screen, wherein a balance valve is arranged on the top of the library body; the PLC is connected with the liquid nitrogen device, a detection device, the control system and the touch screen; the touch screen carries out data exchange with the PLC as a man-machine exchange interface; the liquid nitrogen device comprises a liquid nitrogen tank and a liquid nitrogen pipeline; and the control system comprises a temperature control device, a controlled atmosphere control device and a humidity control device. The one-button intelligent library management system is simple in structure, intelligent in operation and capable of storing and preserving food or vegetables in a diversified manner, and has the functions of detecting and adjusting the oxygen concentration, temperature and humidity.

Description

technical field [0001] The invention relates to a management system for a cold store, a fresh-keeping store or a quick-freezing store, in particular to a one-button intelligent storehouse management system. Background technique [0002] Whether it is for the current cold storage, fresh-keeping storage, or other storage bodies, there are some defects. 1. There is no sensor to detect the oxygen concentration, temperature and humidity in the storage body, which is not conducive to food preservation, storage or quick-freezing. 2. It is impossible to adjust the oxygen concentration, temperature and humidity of the warehouse according to the actual situation, which is not conducive to the preservation, storage or quick freezing of food. 3. Only a single storage or freshness of certain items and food is carried out. Its intelligence is relatively single, and it only stores and keeps a single food or vegetable and fruit fresh. If you often change and store different food, vegetable ...

[0002] Whether it is for the current cold storage, fresh-keeping storage, or other storage bodies, there are some defects. 1. There is no sensor to detect the oxygen concentration, temperature and humidity in the storage body, which is not conducive to food preservation, storage or quick-freezing. 2. It is impossible to adjust the oxygen concentration, temperature and humidity of the warehouse according to the actual situation, which is not conducive to food preservation, storage or quick freezing. 3. Only a single storage or preservation of certain items and foods

Its intelligence is relatively single, and it only stores and keeps a single food or vegetable and fruit fresh. If you often change and store different food, vegetable and fruit, you want to achieve rapid replacement in the existing intelligent relatively single warehouse, and store different foods. When keeping fresh, it is more difficult to shut down the power supply and reset the settings.
