The label identifiers 50 are disposed in one-to-one correspondence with the respective placement layers, and are a first layer label identifier 50a, a second layer label identifier 50b, a third layer label identifier 50c, a fourth layer label identifier 50d, and a fifth layer label identifier 50e, respectively. In this embodiment, the label identifier 50 is provided on the lower surface of the placing plate 13 of the upper placing layer (the label identifier 50a of the first placing layer 15a is provided on the lower surface of the top of the cabinet 10).

Each reagent bottle 200 is provided with a reagent label 201 containing reagent identification information (for example, the reagent identification information may be the number of each reagent bottle 200), and the label identifier 50 can identify the reagent label 201 to obtain the corresponding reagent identification information.

In this embodiment, the reagent label 201 is an RFID label, and as shown in fig. 3, the RFID label can be optionally attached to any part of the reagent bottle 200, such as a bottle body, a bottle bottom, a bottle cap, and the like.

In this embodiment, the number of the tag identifiers 50 corresponds to the number of the placement layers, and each placement layer is provided with one tag identifier 50. Therefore, when the reagent label is identified, the label identifier 50 can accurately identify the reagent discrimination information in each of the set layers, thereby determining in which layer the reagent is extracted or returned by the experimenter. In addition, by numbering the placing layers, a laboratory technician can further extract the reagent in the corresponding placing layer directly according to the record of the position of the reagent during extraction.

The voice prompt device 60 is disposed on the outer surface of the cabinet door 12 or the cabinet body 11, and is used for giving out prompt voice.

In the present embodiment, the internal memory 61 stores recognition error presentation voice information, extraction error presentation voice information, and the like. The recognition error prompting voice is used for prompting by the voice prompting device 60 when receiving a recognition error signal sent by the main control chip 70, and the extraction error prompting voice is used for prompting by the voice prompting device 60 when receiving an extraction error signal sent by the main control chip 70.

In other embodiments, the voice prompt device 60 can also emit other prompt voices, such as a door closing prompt voice for prompting when the cabinet door is not closed for a long time.

The main control chip 70 is disposed in the cabinet 10 and electrically connected to the electronic lock 20, the sensor 30, the identity recognizer 40, the tag recognizer 50, and the voice prompt device 60, respectively.

In this embodiment, the main control chip 70 adopts a conventional control chip, and sends out a corresponding control signal through a preset program. Specifically, the method comprises the following steps:

once the identification information of the experimenter is recognized by the identification recognizer 40 and is transmitted to the main control chip 70 through an electric signal, the main control chip 70 performs an identification determination operation according to the received identification information.

In this embodiment, the identity determination operation performed by the main control chip 70 is to send the identification information to the management server through the communication module of the main control chip 70, and the management server determines whether the received identification information matches with the pre-stored identification information of all experimenters, and if so, sends a door opening permission signal to the main control chip 70. The main control chip 70 sends an unlocking signal to the electronic lock 20 after receiving the door opening permission signal, so that the electronic lock 20 unlocks the cabinet door 12.

In addition, if the management server determines that the identification information does not match, the management server sends a recognition failure signal to the main control chip 70, and the main control chip 70 sends a recognition error signal to the voice guidance device 60 when receiving the recognition failure signal, so that the voice guidance device 60 sends a recognition error guidance voice.

Once the sensor 30 senses that the cabinet door 12 is closed again (i.e., opened and then closed again), and sends a sensing signal to the main control chip 70, the main control chip 70 sends a working signal to the label identifier 50, so that the label identifier 50 can identify the reagent identification information corresponding to all the reagent bottles on each placing plate.

In this embodiment, after the label identifier 50 identifies the reagent discrimination information, the main control chip 70 performs a reagent discrimination operation according to the reagent discrimination information, that is: the reagent discrimination information is sent to the management server through the communication module, the received reagent discrimination information is compared with the previously stored reagent discrimination information in the reagent cabinet by the management server, further, the management server judges whether the missing reagent discrimination information is consistent with the reagent discrimination information previously applied by the experimenter after comparing the missing reagent discrimination information, and if not, an extraction error signal is sent to the main control chip 70. The main control chip 70 sends an error extraction signal to the voice prompt device 60 after receiving the extraction error signal, so that the voice prompt device 60 sends out an extraction error prompt voice.

Meanwhile, in the above process, if the management server compares the added reagent discrimination information, it indicates that the laboratory technician has returned the reagent in the reagent cabinet, and the management server can complete the access monitoring of the reagent according to the added or missing reagent discrimination information.

< example two >

In the second embodiment, the same reference numerals are given to the components having the same configurations as those in the first embodiment, and the description thereof will be omitted.

The second embodiment provides an experiment reagent intelligent management cabinet using a two-dimensional code label as a reagent label. Compared with the first embodiment, the difference lies in that the reagent label 201 'on the reagent bottle 200 is a two-dimensional code label, and the label identifier 50' correspondingly identifying the reagent label is a camera equipped with a two-dimensional code decoding unit, and the specific differences are as follows:

FIG. 4 is a schematic structural diagram of a placement layer in the second embodiment of the present invention

Taking the first layer 15a as an example, as shown in fig. 4, a two-dimensional code label (reagent label 201') on which a two-dimensional code containing reagent discrimination information is printed is necessarily provided on the top of the bottle cap of the reagent bottle 200.

In this embodiment, the label identifiers 50 'are respectively disposed at the top center of each placement layer 15 (the label identifier 50 a' of the first placement layer 15a is disposed on the lower surface of the top of the cabinet 10).

The lens of the camera 51' faces the placing plate 13, and the entire placing layer can be directly photographed and a placing layer image can be obtained each time photographing is performed. The image of the placement layer contains the two-dimensional codes of all the reagent bottles 200 in the current placement layer.

In this embodiment, the camera 51 ' is provided with a two-dimensional code decoding unit 52 ' in a matching manner, and the two-dimensional code decoding unit 52 ' completes the identification and decoding of the two-dimensional code in the placement layer image by adopting an image identification technology and a two-dimensional code identification technology. Specifically, when receiving the working signal sent by the main control chip 70, the camera 51 'will shoot the placement layer to obtain a placement layer image, and further the two-dimensional code decoding unit 52' decodes each two-dimensional code in the placement layer image to obtain a reagent discrimination image corresponding to each placement layer.

Examples effects and effects

According to the experiment reagent intelligent management cabinet that this embodiment provided, because be provided with the electronic lock that can lock the cabinet door in the reagent cabinet, the sensor of response cabinet door switching and the identity recognition ware that discerns is carried out to laboratory technician's identifying information, consequently can judge just let the laboratory technician open the cabinet door when meeting the requirements to laboratory technician's identity before the reagent cabinet is opened, the security of experiment reagent intelligent management cabinet has been improved, also can set for the condition of cabinet door unblock according to actual need, the management to different reagents in the different laboratories of adaptation in a flexible way. Simultaneously, because each reagent bottle all is equipped with the reagent label in the experimental reagent intelligent management cabinet, consequently can distinguish all reagent labels in the reagent cabinet through the label recognizer after the cabinet door is closed, thereby judge the access state of reagent according to the state of reagent label effectively, under this condition, the laboratory technician also can select a reagent cabinet at will and place the reagent that returns on arbitrary one places the board, and worry and cause reagent management confusion, or accurately seek corresponding reagent cabinet and draw reagent according to corresponding reagent position record, the management to the reagent in having made things convenient for greatly and made things convenient for the laboratory technician to the access of experimental reagent, make the laboratory technician can put into the professional experiment more with the energy that is used for managing the reagent originally, improve laboratory technician's work efficiency.

In addition, in the embodiment, the reagent is managed by the intelligent experimental reagent management cabinet, and after an experimenter extracts the reagent, the reagent cabinet can automatically obtain the extraction record of the experimenter according to the identification information of the experimenter and the discrimination information of the reagent, so that additional registration personnel and registration steps are avoided.

In addition, in the embodiment, since the reagent label is an RFID label, the RFID label can be easily installed at each position of the reagent bottle, and the reagent discrimination information of the reagent bottle in each of the placing layers can be easily determined by reading the RFID label of the reagent bottle by an RFID reader. However, RFID tags also have disadvantages, each R

In addition, in the embodiment, the reagent label can also be a two-dimensional code label, and the placing layer is shot by the camera, so that the two-dimensional code corresponding to all the reagent bottles in the current placing layer can be obtained, and further the reagent discrimination information of the reagent bottles in each placing layer can be obtained. Although the setting and identification of the two-dimensional code tag are relatively troublesome compared with the RFID tag, the setting of the content of the tag can be changed more conveniently for the two-dimensional code tag, so that the two-dimensional code tag can be adapted to different management in different laboratories more easily.

In addition, in the embodiment, voice prompt device can carry out corresponding suggestion through pronunciation to the laboratory technician, realizes the function of experiment reagent intelligent management cabinet better. For example, when a laboratory technician takes out wrong reagents (for example, reagents with smaller differences due to similar colors) from a reagent cabinet due to errors and the like, an extraction error prompt voice can be generated to prompt the laboratory technician, so that the problems of errors and the like in the experiment due to reagent taking errors can be further avoided, and the management effect of the reagent in a laboratory is finally and better improved.

The above-described embodiments are merely illustrative of specific embodiments of the present invention, and the present invention is not limited to the description of the above-described embodiments.

For example, in the embodiment, the identity determination operation and the reagent determination operation performed by the main control chip are performed by sending corresponding information through the management server to complete corresponding operations. In other embodiments, the main control chip may also be a microprocessor having a storage unit and a determination unit, wherein the storage unit stores the identification information of the experimenter and the reagent identification information identified by the label identifier last time in advance. When the identity judgment operation is carried out, the judgment unit completes the judgment according to the received identification information and the identification information stored in the storage unit; when a reagent discrimination operation is performed, the discrimination unit performs discrimination based on the reagent discrimination information recognized by the label recognizer this time and the reagent discrimination information stored in the storage unit. In this case, the reagent access state can be monitored only by the intelligent laboratory reagent management cabinet, and the system can be applied to facilities such as a small laboratory without a management server. In addition, even if the reagent data needs to be managed through the management server, the experimental reagent intelligent management cabinet can directly send the judged missing or added reagent judgment information to the management server so as to complete the monitoring of the reagent access state.

For example, in the above-described embodiment, the identification information is door card information in a door opening card held by an experimenter, and the identification portion is a door card reading device. As an alternative scheme, the identification information may also be adjusted to be a password, a two-dimensional code containing the identity information of the experimenter, the fingerprint information of the experimenter, or face information according to the actual demand, and an identity identification portion corresponding to the identification information, that is, a password input device, a two-dimensional code scanning device, a fingerprint identification device, or a face identification device, is provided in a matching manner. Through such mode, also can realize authentication's effect, the laboratory technician can operate identification portion through corresponding mode, lets identification portion discern this laboratory technician's identification information through operations such as input password, scanning two-dimensional code, verification fingerprint, shooting people's face promptly.

For example, in the first embodiment, the RFID reader (tag identifier) is disposed on the lower surface of the placing board of the upper placing layer, and alternatively, may be disposed on the top, bottom, wall surface of the placing layer or embedded in the placing board according to actual conditions.

For example, in the second embodiment, one camera is provided at the center of the interlayer board above each placement layer. However, if the height of the placing layer is low, and the shooting range of the camera is insufficient, in order to ensure that all two-dimensional codes in the placing layer can be completely shot, a plurality of cameras can be arranged on each interlayer plate above the placing layer, and the whole placing layer image of the placing layer is obtained by splicing.

For example, in other aspects of the present invention, the electronic lock body and the lock catch may be oppositely disposed, that is, the electronic lock body is disposed on the cabinet door, and the lock catch is disposed on the cabinet body. In this way, automatic unlocking and locking of the reagent cabinet door can also be achieved.
