[0025] Device Embodiment

[0026] The embodiment of the present invention provides a sample flow box, according to Figure 1-Figure 6 It can be seen that the sample flow box of the embodiment of the present invention includes:

[0027] Box body 2, box cover 1, smart lock, smart lock controller arranged in the middle of the box cover and QR code 3 fixed on the box body;

[0028] The rear side of the box body 2 is hinged to one side of the box cover 1 through a hinge;

[0029] The smart lock comprises: a lock tongue 8 and a lock buckle 4, wherein the lock tongue 4 is arranged on the inner side of the box cover 1, and the lock buckle 4 is arranged on the inner side of the box body 2;

[0030] The smart lock controller controls the pop-up and retraction of the smart lock bolt 8.

[0031] The box cover 1 includes a hollow frame structure and a filler. The hollow frame structure of the box cover 1 is made of stainless steel, and the box cover filler is divided into two layers, an upper layer and a lower layer.

[0032] The filler of the box cover 1 is made of fireproof cotton material.

[0033] The smart lock controller is arranged between the upper and lower layers of fillers of the box cover 1.

[0034] A positioning device is further arranged in the middle of the box cover 1 .

[0035] A lock housing is arranged outside the lock tongue 8 .

[0036] A stainless steel handle is arranged above the box cover 1 .

[0037] Mechanical locks are further provided on the box body 2 and the box cover 1 to enhance the confidentiality of the circulation box.

[0038] A UHF RFID tag is further arranged inside the box cover, and the UHF RFID tag includes encrypted sample information.

[0039] The sample information stored in the UHF RFID tag is encrypted by an encryption method, specifically including:

[0040] Obtaining sample information, wherein the sample information includes: sampling location, sampling date, coal sample type and coal sample number;

[0041] The sample information is converted into a ciphertext after being encrypted using the AES algorithm;

[0042] The ciphertext is written into the UHF RFID tag.

[0043] In a specific implementation of this embodiment, a UHF RFID tag is further arranged in the box cover 1 to realize the circulation tracking of the sample box and the acquisition of key information. In a specific implementation, the data in the UHF RFID tag is first encrypted by using encryption algorithms such as AES and RSA. For example, the tag contains detailed information of the sample box, such as the origin of the coal sample, the sampling date, the sampling number, and the quality of the coal sample, so as to prevent the data from being illegally obtained and tampered with; then, a unique ID code is assigned to each UHF RFID tag, which can not only prevent the tag from being forged or copied, but also track and identify the tag through the unique code when it is illegally read or tampered with. The encrypted data is stored in the dedicated storage area of ​​the UHF RFID tag to ensure the security and integrity of the data. The UHF RFID tag is attached to the sample box, and the UHF RFID reader is deployed at the key nodes of the sample box circulation (such as the warehouse entrance, exit, production line, etc.) to read and write the tag information. When the sample box passes the reader, the reader automatically reads the tag information and records it into the database together with the current time, location and other information. Through the records in the database, the circulation of sample boxes can be monitored in real time, including their location, status, circulation speed, etc. If an abnormal situation occurs during the circulation of a sample box (such as loss, delay, etc.), the system can automatically alarm and prompt relevant personnel to handle it.

[0044] The implementation principle of the present invention specifically includes:

[0045] Put the coal sample into the sample circulation box, then scan the QR code 3 through the APP, and click to lock through the APP. When locking, the lock tongue pops out in the lock shell 5 driven by the drive motor 7, passes through the lock buckle 4 and extends into the lock hole 9 to achieve locking. The new type of use is further provided with a mechanical lock to enhance the safety of the sample. After locking, the real-time monitoring of the sample trajectory is achieved through the built-in positioning device. When unlocking, the QR code is scanned through the APP and the user authority is verified. The user clicks to unlock, and the lock tongue 8 bounces back into the lock shell 5 driven by the drive motor 7.

[0046] By adopting the embodiment of the present invention, it is possible to scan the QR code on the box to determine whether the unlocker has the unlocking authority, and control the switch of the smart lock through the smart lock controller, thereby improving the confidentiality of the sample. In addition, the filling materials of the box body and the box cover of the embodiment of the present invention are fireproof cotton, which ensures the safety of the sample.
