Description

Technical Field

[0001] The utility model relates to the technical field of file management cabinets, in particular to an intelligent file cabinet based on RFID technology. Background Art

[0002] The smart file cabinet based on RFID technology is an intelligent storage device that combines modern radio frequency identification (RFID) technology and is mainly used for managing, storing and tracking file documents.

[0003] Some existing smart file cabinets based on RFID technology usually face some challenges when used in harsh environmental conditions, because the performance and stability of the smart file cabinets may be affected in harsh environments with extreme temperatures and high humidity. First of all, the core components of RFID technology, including RFID readers and tags, have certain requirements for environmental temperature and humidity. If they are in a high humidity environment for a long time, it may cause circuit components to rust or short-circuit, thereby affecting the normal operation of the RFID reader, and further affecting the effective management and protection of file documents. Secondly, if the environment is too humid, it may also cause the files to be damaged by moisture. Utility Model Content

[0004] The purpose of the utility model is to provide an intelligent file cabinet based on RFID technology to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An intelligent file cabinet based on RFID technology comprises: a cabinet body, a cabinet door is arranged in the opening direction of the cabinet body, a control panel is fixed on one side of the cabinet body, a receiving cabinet is arranged on the inner side of the cabinet body, a plurality of reserved openings are opened on one side of the receiving cabinet, a fixing column is fixed on one side of the receiving cabinet, a dehumidification component is fixed on the upper side of the fixing column, and a plurality of RFID readers are also arranged on the inner side of the cabinet body;

[0007] The dehumidification component includes a refrigeration compressor, which is fixed on the upper side of the fixed column, the output port of the refrigeration compressor is connected to capillary tube 1, one side of the capillary tube 1 is connected to an evaporator, a condenser is arranged on the lower side of the evaporator, the output port of the condenser is connected to capillary tube 2, one side of the capillary tube 2 is connected to the refrigeration compressor, and a fan component is fixed on the lower side of the condenser.

[0008] The dehumidification component starts working, the refrigeration compressor starts, and the refrigerant starts to circulate. The refrigerant first enters the evaporator through capillary tube 1. In the evaporator, the refrigerant absorbs heat, causing the surface temperature of the evaporator to drop. At the same time, the micro motor fixed on the connecting plate in the fan component starts to drive the impeller to rotate. The rotation of the impeller generates airflow, which sucks the air in the cabinet and blows it to the evaporator. When the air flows through the evaporator, the water vapor in the air condenses into water droplets on the cold surface of the evaporator, thereby reducing the humidity of the air. Subsequently, the dehumidified air flows through the condenser. At this time, the refrigeration compressor has compressed the refrigerant into a high-temperature and high-pressure gas and sent it to the condenser. In the condenser, the refrigerant releases heat and condenses into liquid, while discharging the heat brought out by the evaporator to the outside of the cabinet. The liquid refrigerant then returns to the refrigeration compressor through capillary tube 2 again, completing a refrigeration cycle. Capillary tube 2 plays a role in throttling and reducing pressure, so that the refrigerant reduces the pressure and temperature before entering the refrigeration compressor. This cycle is repeated continuously.

[0009] Preferably, the wind turbine component comprises a connecting plate, the connecting plate is fixed on the upper side of the fixing column, a micro motor is fixed on the upper side of the connecting plate, and an impeller is fixed at the output end direction of the micro motor via a connecting rod.

[0010] The fan component continuously draws air from the cabinet and dehumidifies it through the evaporator, then blows the dry air back into the cabinet, thus maintaining the humidity inside the cabinet at an appropriate level.

[0011] Preferably, a temperature and humidity sensor is also fixed to the inner wall of the cabinet body, and the temperature and humidity sensor is arranged between two groups of receiving cabinets, and the temperature and humidity sensor is located on the upper side of the dehumidification component.

[0012] The temperature and humidity sensor monitors the temperature and humidity conditions inside the cabinet in real time. When the humidity exceeds the set threshold, the temperature and humidity sensor will send a signal to the external control system. After receiving the signal, the control system will automatically start the dehumidification component to perform dehumidification operations until the humidity drops to an appropriate range.

[0013] Preferably, the containing cabinet comprises a containing cabinet body, a plurality of containing cabinet bodies are provided on the inner side of the cabinet body, files are arranged on the inner side of the containing cabinet body, and RFID tags are adhered to the files.

[0014] Preferably, the plurality of groups of RFID readers are located on the top of the cabinet body.

[0015] The smart file cabinet also exchanges information with the RFID tag attached to the file through the RFID reader / writer fixed on the upper side of the cabinet body. Users can operate it through the control panel. After the system recognizes the user's authority, it controls the corresponding RFID reader / writer to read or write the information of the RFID tag, thereby realizing the automatic management and tracking of the files.

[0016] Preferably, the fixing columns are cylindrical in shape, and are arranged equidistantly in a rectangular array.

[0017] The fixed column is arranged in a cylindrical shape to facilitate air circulation of the dehumidification component.

[0018] Preferably, the reserved opening is in a rectangular shape and is opened through the cabinet body.

[0019] The reserved opening on one side of the cabinet facilitates air circulation and improves the overall dehumidification effect.

[0020] Compared with the prior art, the utility model provides an intelligent file cabinet based on RFID technology, which has the following beneficial effects:

[0021] The utility model can quickly reduce and stabilize the humidity inside the cabinet through the coordinated work of dehumidification equipment and temperature and humidity sensors, effectively preventing RFID tags and files from being damaged by moisture, and ensuring the safety and reliability of the storage environment. At the same time, the design of the storage cabinet provides an independent storage space for each file, which is easy to manage and find. Through the RFID reader and writer, information is exchanged with the RFID tag of the file. The user only needs to operate the control panel simply to quickly find or manage a specific file, thereby improving work efficiency. While improving the safety and reliability of the file storage environment, the utility model also greatly simplifies the management process. BRIEF DESCRIPTION OF THE DRAWINGS

The pressure and temperature are reduced before entering the refrigeration compressor 70. This cycle is repeated continuously. The fan component 75 continuously draws the air in the cabinet 1 and dehumidifies it through the evaporator 73, and then blows the dry air back into the cabinet 1, thereby maintaining the humidity inside the cabinet 1 at a suitable level. At the same time, the temperature and humidity sensor 8 monitors the temperature and humidity conditions in the cabinet 1 in real time. When the humidity exceeds the set threshold, the temperature and humidity sensor 8 will send a signal to the external control system. After receiving the signal, the control system will automatically start the dehumidification component 7 to perform the dehumidification operation until the humidity drops to a suitable range.
