Therefore, when there are many types of samples and they need to be stored separately, multiple hazardous chemical management cabinets are needed for storage. Then, since each management cabinet needs to identify user permissions, when the user needs to operate multiple hazardous chemical management cabinets at the same time, they need to be verified one by one and then operate. When operating each hazardous chemical management cabinet, parameters need to be set one by one, which seriously reduces work efficiency. Utility Model Content

[0003] In view of this, the purpose of the present invention is to provide an expandable and combined hazardous chemicals management cabinet system to solve the problem of low efficiency and low safety performance of multiple management cabinets during the management process.

[0004] The utility model adopts the following scheme: the application provides an expandable and combined hazardous chemicals management cabinet system, including a master control device and a plurality of hazardous chemicals management cabinets, each cabinet being provided with a control module and a first LORA wireless transceiver module;

[0005] The master control device is separately arranged from the cabinet, and includes a rights management module, an operation module, and a second LoRa wireless transceiver module suitable for connecting to the first LoRa wireless transceiver module through a wireless signal; wherein the rights management module is connected to the operation module to unlock the operation module after the user passes the verification of the rights management module so that the user can send control instructions to any one or more control modules in the cabinet through the operation module;

[0006] A plurality of the cabinets are arranged in an array, and connecting fixings are arranged between adjacent cabinets to connect the cabinets to each other; each cabinet is provided with an electronic lock, and the electronic lock is suitable for opening and closing under the control of a control module.

[0007] Furthermore, the master control device is a control terminal tablet.

[0008] Furthermore, the cabinet is configured in a square shape to facilitate assembly.

[0009] Furthermore, the authority management module includes at least one of a face recognition module, an NFC card recognition module, and an IC card recognition module.

[0010] Beneficial effects:

[0011] This solution uses a master control device that is separated from the cabinet. The master control device is provided with a permission management module to identify whether the user has the permission to operate the master control device to control the cabinet. When the user has the permission, all cabinets can be controlled simultaneously through a master control device, so that the user can control all cabinets at any time after a verification, without the need to verify one by one. At the same time, when all cabinets need to be manipulated, it can be achieved by operating the same master control device, which solves the problem of wasting a lot of time by traditional manipulation one by one. By setting a LORA wireless transceiver module to realize control connection of multiple cabinets, the operating current of the LORA wireless transceiver module is only a few milliamperes, and the power consumption is extremely low. Therefore, the entire chemical cabinet only needs 5V and 1A for power supply. Compared with the problem of instantaneous current that is easy to generate in the existing signal transmission method, the LORA wireless transceiver module can greatly improve the power safety of the entire hazardous chemical storage room.
