Specific embodiment one

[0038] An intelligent safety explosion-proof cabinet and its control system include: a control cabinet, two explosion-proof storage cabinets, a controller, a touch screen display 8, a face recognition device 9, a card reader, a weighing unit, a temperature and humidity sensor, a storage unit 17, an explosion-proof audible and visual warning device 10, an RFID reading and writing unit for reading the detected label content, and an RFID scanning antenna 11 for scanning and identifying product labels.

[0039] The control cabinet contains, from top to bottom, a control room, a weighing room, a power supply room, and an exhaust room. The control room contains a controller, an identification device, and an RFID reader / writer unit. The weighing room contains a weighing unit and an electric lock. The power supply room contains an uninterruptible power supply. The explosion-proof storage cabinet contains a storage room and an exhaust room.

[0041] 1) Upon first card swipe, the left door can be opened, but the right door remains locked;

[0042] 2) Swipe the card again; the left door will close, and the right door can be opened.

[0043] 3) You must tap the double door button on the touchscreen display and swipe your card to open both doors simultaneously;

[0044] The explosion-proof storage cabinet has multiple side walls and bottom surfaces with a double-layer hollow structure.

In this way, the exhaust duct does not occupy the indoor space, saves the laboratory space, and improves the ventilation efficiency.

[0047] The upper and lower storage units are staggered in the explosion-proof storage cabinet to form an S-shaped air flow channel 20, preventing wind flow dead angles.

[0048] The storage unit comprises a storage rack 1701, a support column 1702, a positioning plate 1703, a positioning opening 1704, and a sealing cover plate 1705. The storage rack is arranged in the explosion-proof storage cabinet, the support column is arranged on the side wall of the storage rack, the RFID scanning antenna is arranged inside the storage rack, and the bottom surface of the storage rack is packaged with the sealing cover plate. The sealing cover plate seals the RFID read-write device, which can not only prevent volatile gases from damaging the antenna, but also prevent reagent bottles or users from colliding with the antenna, thereby improving safety and ensuring the accuracy of antenna detection.

[0049] The positioning plate is connected with the support column, and a storage groove is formed between the positioning plate and the storage rack. The positioning plate is provided with a positioning opening allowing the product to pass through. The size specification and number of the positioning opening can be set according to the actual use requirements of the user, so that there is a gap between the reagent bottles, the number of reagents in the cabinet is controlled by physical methods, the reagent bottles are prevented from colliding with each other, and the safety is improved.

[0050] When using an intelligent safety explosion-proof cabinet and its control system, two steps of storing reagents and taking reagents are included.

[0054] The controller obtains the reagent weight information of the weighing unit, and opens the corresponding explosion-proof storage cabinet according to the storage instruction;

[0055] The reagent to be stored is placed in the positioning opening with appropriate size, and then the cabinet door is closed. The RFID scanning antenna scans and reads the label on the reagent to be stored, and transmits the information on the label to the controller through the RFID read-write unit;

[0056] The controller displays the reagent storage information on the touch control display screen, wherein the reagent storage information includes storage personnel information, reagent name, reagent weight, actual number, etc.

[0057] When taking reagents:

[0061] The controller judges the name and quantity of the reagent taken out according to the label information before and after the access;

[0062] The reagent taken out is placed on the weighing unit, and the weighing unit weighs the reagent;

[0063] After the controller obtains the reagent weight information of the weighing unit, the reagent access information is displayed on the touch control display screen, wherein the reagent access information includes access personnel information, reagent name, reagent weight, and reagent quantity.
