Intelligent management function of intelligent reagent cabinet

　　The inventory management function of the intelligent reagent cabinet is one of its core functions, which is based on the technology of the Internet of Things, big data and artificial intelligence, and realizes the automatic identification, rapid access, accurate measurement and safe storage of reagents, providing a more convenient and efficient reagent management method for laboratory managers. The following is a detailed introduction to the inventory management function of the intelligent reagent cabinet:

　　1. Automatic identification and recording of reagents

　　The smart reagent cabinet automatically identifies the collection and return information of the reagent through RFID (radio frequency identification) technology or barcode scanning technology. Rfid-type intelligent reagent cabinet without manual operation, you can quickly inventory data, record the storage location, quantity, use records and other information of reagents. The information is automatically formed into electronic ledger, which reduces the errors and omissions of manual recording and improves the accuracy of data. For example, when the experimenters take out a bottle of chemical reagent for the experiment, the system will immediately reduce the quantity of the reagent in stock by one, and record the time of withdrawal, operator and other information. In this way, managers can accurately know the actual quantity of each reagent in the cabinet at any time.

　　It can also be integrated with the laboratory's information management system (LIMS) to synchronize inventory data to the management platform of the entire laboratory, so as to facilitate personnel in different departments to view inventory status and realize efficient sharing of laboratory resources.

　　Second, intelligent inventory warning

　　The smart reagent cabinet has the ability to set the inventory warning line, and when the inventory is below the preset threshold, the system will automatically issue an alarm to remind the administrator to replenish the reagent in time. This function helps to avoid reagent shortages or expired backlogs and ensure the smooth progress of laboratory scientific research. This may be through sound, flashing lights, or notifications to managers' mobile devices to alert them to timely restocking. For example, for commonly used buffer solution reagents, if the inventory is less than 10 bottles, the system will remind the buyer to make a purchase.

　　3. Diversified process control

　　The intelligent reagent cabinet can set a variety of management processes for different reagents, define special control items categories and control processes, and separately control dangerous chemicals. This helps to realize the fine and trace management of the reagent and ensure the safe use of the reagent.

　　4. Real-time environmental monitoring

　　The intelligent reagent cabinet monitors the temperature, humidity, light and other environmental factors of the reagent in real time through sensors and other technologies to ensure the safety of the reagent storage environment. At the same time, it is equipped with VOC gas detection sensor and air filtration system to ensure the air quality in the cabinet and provide a safe storage environment for reagents.

　　5. Authority management and security control

　　The intelligent reagent cabinet comes with a face recognition system, a card identity system, SMS verification system and other permission verification methods to ensure that only authorized personnel can access and operate the cabinet. In addition, it is also equipped with physical electronic control integrated lock and mechanical key backup, to meet the requirements of public security supervision, with anti-theft robbery function. These security measures help protect the safety of the reagents and prevent them from being illegally obtained or misused.

　　6. Data visualization and decision support

　　The smart reagent cabinet can generate detailed reports and analysis results to help laboratory managers better understand reagent usage and inventory status. These data provide decision support for experimental planning and procurement, and help to optimize the allocation of laboratory resources and improve the efficiency of scientific research.

　　7. Remote monitoring and management

　　The intelligent reagent cabinet uses Internet of Things technology to achieve remote monitoring and management functions. Through the Internet or local area network, managers can view the status of the reagent cabinet in real time, inventory information and operation records, etc., to achieve remote management and control of the reagent cabinet. This feature helps laboratory managers respond and handle anomalies in a timely manner, ensuring safe laboratory operation.

　　Eight, inventory warning function

　　You can set the upper and lower limits of inventory. When the inventory of a certain reagent is below the preset lower limit, the system will automatically issue a low inventory warning. This may be through sound, flashing lights, or notifications to managers' mobile devices to alert them to timely restocking. For example, for commonly used buffer solution reagents, if the inventory is less than 10 bottles, the system will remind the buyer to make a purchase.

　　Similarly, when the amount of inventory exceeds the upper limit, the system will also send a warning, which helps to avoid waste and storage space caused by over-procurement of reagents.

　　9. Reagent positioning function

　　- Each storage location in the smart reagent cabinet has a corresponding number or coordinate. When you need to find a reagent, the inventory management system can quickly locate the specific location of the reagent. Just like in a large warehouse, the system can precisely find the shelves and positions of the goods. This is very useful in large reagent cabinets or in cases where there is a large amount of reagent storage, and can greatly save time in finding reagents.

　　10. Inventory automation

　　Traditional reagent inventory requires manual checking of reagent quantity and information one by one, which is time-consuming and laborious. The inventory management function of the intelligent reagent cabinet can realize automatic inventory. It can automatically scan all reagents in the cabinet at set intervals (such as every night or once a week) to generate detailed inventory reports. The report includes the reagent name, specification, quantity, expiration date and other information, and compares it with previous inventory records to quickly identify possible discrepancies, such as missing reagents or incorrect records.

　　11. Validity period management

　　The system records the expiration date of each reagent. It can sort and remind reagents in order of expiration date. For reagents that are about to expire, advance notice will be issued to remind management to prioritize the use or disposal of these reagents. For example, for a drug reagent with a validity period of only one month, the system will mark it as a focus object and highlight it in the inventory management interface, so that the experimenter can reasonably arrange the experiment and avoid the reagent expiration waste.

　　In summary, the inventory management function of the intelligent reagent cabinet has the characteristics of automatic identification and recording of reagents, intelligent inventory early warning, diversified process control, real-time environmental monitoring, authority management and security control, data visualization and decision support, and remote monitoring and management. These functions together constitute an efficient, safe and intelligent reagent management system of the intelligent reagent cabinet, which is of great significance for improving the management level of the laboratory and the efficiency of scientific research work.
