The embodiment relates to an intelligent management system for experimental reagents, which is arranged in a laboratory.

As shown in fig. 1, the intelligent experimental reagent management system 100 includes j reagent cabinets 1, one management server 2, a plurality of laboratory staff terminals 3, and communication networks 4a and 4 b.

The management server 2 is respectively connected with the reagent cabinets 1 in a communication way through a communication network 4a, and is respectively connected with the laboratory technician terminals 3 in a communication way through a communication network 5 a. In this embodiment, the communication networks 4a and 4b are both local area networks in a laboratory.

The reagent cabinet 1 is used for storing reagent bottles containing various reagents required by chemical experiments, such as general reagents, analytical reagents and the like. In this embodiment, each reagent cabinet has its own cabinet number, for example, the first reagent cabinet has a cabinet number GH1, and the jth reagent cabinet has a cabinet number GHj.

FIG. 2 is a schematic structural diagram of a reagent cabinet according to an embodiment of the present invention.

As shown in fig. 2, the reagent kit 1 includes a kit body 11, a kit door 12 provided on the kit body, a locking portion 13, a sensing portion 14, five placement layers 15 located in the kit body, five determination portions 16 provided in one-to-one correspondence with the placement layers 15, and an identification portion 17, a warning portion 18, and a main control chip 19.

The locking portion 13 comprises an electronic lock 131 arranged at the edge of the cabinet door and a catch (not shown) arranged on the door frame. The electronic lock 131 can lock and unlock the cabinet door 12 according to the control signal of the main control chip 19 under the cooperation of the lock catch.

The sensing part 14 is a sensor disposed on the cabinet door 12, and is used for sensing the opening and closing of the cabinet door and generating a corresponding sensing signal.

The placing layer 15 is provided with five layers and is used for placing various reagent bottles. In the reagent cabinet 1, a first layer containing layer 15a, a second layer containing layer 15b, a third layer containing layer 15c, a fourth layer containing layer 15d and a fifth layer containing layer 15e are arranged from top to bottom in sequence. Wherein, each layer of the placing layer 15 has a placing plate on which the reagent bottles are placed (the placing plate of the fifth layer of the placing layer 15e is the bottom plate of the reagent cabinet 1).

FIG. 3 is a schematic view showing the arrangement state of a reagent bottle in the embodiment of the present invention.

Taking the first-layer placing layer 15a as an example, as shown in fig. 3, the reagent bottles 151 can be freely placed on the placing plate 153. A reagent label 152 is provided on the cap of the reagent bottle 151.

In this embodiment, the reagent label 152 is a two-dimensional code label on which a two-dimensional code containing reagent discrimination information corresponding to the current reagent bottle 151 is printed.

The determination unit 16 is a two-dimensional code recognizer, and includes an imaging unit 161 and a two-dimensional code determination unit 162. In the reagent tank 1, the determination units 16 are provided in one-to-one correspondence with the respective storage layers 15, and include a first layer determination unit 16a, a second layer determination unit 16b, a third layer determination unit 16c, a fourth layer determination unit 16d, and a fifth layer determination unit 16 e. In this embodiment, the determination section 16 is provided on the lower surface of the mounting plate 153 of the upper-stage mounting stage 15 (the determination section 16a of the first-stage mounting stage 15a is provided on the lower surface of the top of the cabinet 11).

The image pickup unit 161 is a single camera, and as shown in fig. 3, a lens of the image pickup unit 161 faces the placing plate 153, so that the two-dimensional code label 152 on the entire placing layer 15 and each reagent bottle 151 on the placing layer 15 can be directly picked up, and a corresponding placing layer image can be obtained.

The two-dimensional code discrimination unit 162 can discriminate all the two-dimensional codes in the image by discriminating the image of the placement layer captured by the imaging unit 161 based on the two-dimensional code recognition technique, and decode the reagent discrimination information corresponding to each two-dimensional code.

The identification part 17 is a door card reading device for identifying a door opening card held by an experimenter.

In this embodiment, the door opening card includes identification information of an experimenter, and the identity recognition portion 17 enables the experimenter to recognize the identification information corresponding to the experimenter in the door opening card in a card swiping manner.

Fig. 5 is a content stored in the counter number layer number storage unit in the embodiment of the present invention.

In this embodiment, in order to distinguish the reagent cabinets 1, each reagent cabinet 1 in the laboratory is provided with a cabinet number for identification. Meanwhile, in each reagent cabinet 1, the respective placing layers 15 are also provided with corresponding layer numbers in sequence, for example, the placing layer 15 of the first layer has a layer number of 1. As shown in fig. 5, the rack number-layer number storage unit 192 stores a rack number 1921 of the current reagent rack 1, a layer number 1922 of each rack layer 15, and a determination unit number 1923 of the determination unit 16 corresponding one-to-one to each layer number 1922. In practical applications, the cabinet number is a chip identification code of the main control chip 19, and the identification unit number is a machine code of each identification unit.

When a laboratory technician takes out or returns a reagent and closes the cabinet door 12, once the sensing part 14 senses that the cabinet door 12 is closed, the main control chip 19 controls the locking part 13 to lock the cabinet door 12, and controls the judging parts 16 to shoot images of the placing layers and judge reagent judging information of all reagent bottles 15 in the corresponding placing layers, at this time, the main control chip 19 corresponds the judged reagent judging information with the layer number corresponding to the judging part 16 making the judgment, and further controls the reagent cabinet communication part 191 to send the judged reagent judging information, the corresponding layer number and the current cabinet number of the reagent cabinet 1 to the management server 2 for processing.

Fig. 6 is a functional block diagram of a management server in an embodiment of the present invention.

As shown in fig. 6, the management server 2 includes a reagent-related information storage unit 21, a search acquisition unit 22, a comparison determination unit 23, a related information update unit 24, a request record storage unit 25, an extraction record storage unit 26, an identity search determination unit 27, a reagent name check unit 28, a service-side communication unit 29, and a service-side control unit 30 for controlling the above units.

The reagent-related information storage unit 21 stores reagent-related information for each reagent bottle 151 in a laboratory.

As shown in fig. 7, the reagent-related information storage unit 21 stores the following information: reagent discrimination information 211, and corresponding reagent name 212 and reagent position information 213. Specifically, the method comprises the following steps:

the reagent discrimination information 211 is the number information of the reagent bottles 151, and the reagent labels on the respective reagent bottles 151 contain the reagent discrimination information indicating the respective different numbers.

The reagent name 212 is a reagent name of the reagent contained in the reagent bottle 151.

The reagent position information 213 includes the cabinet number of the reagent cabinet 1 and the layer number of the placement layer 15.

As can be seen from the above figure, the reagent position information corresponding to the different reagent discrimination information 211 may be the same, and if the reagent position information corresponding to the reagent discrimination information P1 and P2 are the same, it indicates that two reagent bottles containing different reagents are stored in the same storage layer 15 of the same reagent kit 1.

The reagent identification information P2, P3, and P4 correspond to the same reagent name, but the corresponding reagent position information is different, indicating that three reagent bottles containing the same reagent are placed at different positions (the reagent bottles corresponding to P2 and P3 are placed on different placement levels 15 of the same reagent box 1, and the reagent bottles corresponding to P4 are placed in other reagent boxes 1).

The reagent position information corresponding to the reagent discrimination information P5 and P7 is null, and indicates that the reagent bottle corresponding to the reagent discrimination information is in a state of being extracted by the laboratory technician and is not in the reagent tank 1.

After the laboratory technician terminal 3 inputs the name of the required reagent to be searched and transmits the required reagent name and the identification information of the laboratory technician to the management server 2, the search acquisition unit 22 receives the required reagent name from the laboratory technician terminal 3 via the service-side communication unit 29, searches the reagent-related information storage unit 21, and acquires the corresponding reagent position information.

In the present embodiment, after the search acquiring unit 22 acquires the reagent site information, the service-side control unit 30 further controls the service-side communication unit 29 to transmit the searched reagent site information and the received required reagent name to the corresponding laboratory technician terminal 3 as one piece of extracted information based on the received identification information.

Fig. 8 is the content of the extracted information in the embodiment of the present invention.

Taking the input required reagent name SJ2 as an example, as shown in fig. 8, the extraction information 221 includes the reagent name 2211 and the corresponding reagent position information 2212. It can be seen that the reagent position information in the extraction information 221 may be multiple, and reagents representing the needs of the laboratory technician are stored at multiple positions.

Once the laboratory technician takes out the reagent bottles 151 from the reagent cabinet 1 or returns the reagent bottles 151 according to the extracted information, the determination unit 16 determines the reagents in the storage layers 15 and obtains the reagent determination information of all the reagent bottles 151 in each storage layer 15 after the sensing unit 14 senses that the laboratory technician closes the cabinet door 12, and at this time, the main control chip 19 controls the reagent cabinet communication unit 191 to transmit the reagent determination information, the layer number corresponding to the reagent determination information, and the cabinet number to the management server 2.

The comparison determination unit 23 is configured to determine missing or added reagent discrimination information by comparing all the received reagent discrimination information with the reagent discrimination information of the same layer number and the same cabinet number in the reagent-related information storage unit 21, based on the layer number and the cabinet number received by the service-side communication unit 29.

In the present embodiment, the missing reagent discrimination information is reagent discrimination information that exists in the reagent discrimination information stored in the reagent-related information storage unit 21 but not transmitted from the reagent cabinet 1, on the basis of the same layer number and cabinet number; the added reagent discrimination information is the reagent discrimination information existing in the reagent discrimination information transmitted from the reagent kit 1, not stored in the reagent-related information storage unit 21, but the same layer number and the same kit number.

The related information updating unit 24 is used to update the reagent discrimination information and the reagent position information in the reagent related information storage unit 21. Specifically, the method comprises the following steps:

when the comparison determination unit 23 compares the missing reagent discrimination information (that is, when the plurality of pieces of reagent discrimination information stored in the reagent related information storage unit 21 include reagent discrimination information that is not included in the received reagent discrimination information and indicate that the reagent bottle 151 is taken out from the rack layer 15), the service-side control unit 30 controls the related information update unit 24 to delete the corresponding reagent position information in the reagent related information storage unit 21 based on the missing reagent discrimination information (in this case, the reagent position information corresponding to the reagent discrimination information is empty, indicating that the reagent has been taken out).

When the comparison determination unit 23 compares the added reagent discrimination information (that is, the received plurality of pieces of reagent discrimination information include the reagent discrimination information not included in the reagent discrimination information stored in the reagent related information storage unit 21 and indicate that a new reagent bottle 151 is inserted into the rack 15), the service-side control unit 30 controls the related information update unit 24 to store the corresponding cabinet number and layer number as new reagent position information in the reagent related information storage unit 21 in association with the corresponding reagent position information based on the added reagent discrimination information.

Fig. 9 is a diagram of contents stored in the request record storage section in the embodiment of the present invention.

Once the retrieval acquiring unit 22 retrieves the reagent site information, the request record storage unit 25 stores the reagent site information in association with the required reagent name and the identification information received from the laboratory technician terminal 3, and as shown in fig. 9, the request record storage unit 25 stores therein a plurality of request records each including a required reagent name 251, all of the reagent site information 252 corresponding to the required reagent name 251, and identification information 253 of the laboratory technician who requested the required reagent name 251. The identity search determination unit 27 can determine whether or not the laboratory technician has the authority to open the reagent kit 1 based on the kit number in the reagent position information by using each request record.

Fig. 10 is a diagram of the contents stored in the extraction record storage section in the embodiment of the present invention.

When the related information update unit 24 deletes the corresponding reagent position information in the reagent related information storage unit 21 based on the missing reagent discrimination information, the extraction record storage unit 26 stores the missing reagent discrimination information and the identification information received from the reagent kit 1 in association with each other as one extraction record. As shown in fig. 10, the extraction record storage unit 26 stores a plurality of extraction records, each of which includes a piece of missing reagent discrimination information 261 and corresponding identification information 262, and the missing reagent discrimination information 261 is extracted by an experimenter having the identification information 262.

When the laboratory technician identifies the identification information 17 using the door-opening card, the reagent kit communication unit 191 transmits the identified identification information and the kit number of the reagent kit to the management server 2, and the identification search determination unit 27 searches the request record storage unit 25 and the extraction record storage unit 26, respectively, based on the received identification information and the received kit number, to determine whether or not the laboratory technician has the right to open the reagent kit.

Specifically, when searching the request record storage unit 25, the identity search determination unit 27 searches the request record storage unit 25 based on the received identification information and the cabinet number, and determines whether or not there is matching identification information and cabinet number; when searching the extracted record storage unit 26, the identity search determination unit 27 searches the extracted record storage unit 26 based on the received identification information and determines whether or not there is matching identification information.

When the laboratory technician extracts a necessary reagent bottle and returns an unnecessary reagent bottle, and recognizes the reagent discrimination information through the steps S12-6 to S12-11 (steps S13-5 to S13-10), the steps S12-12 and S13-11 can be performed simultaneously, and the comparison determination unit 26 can determine which reagent bottles the laboratory technician extracted and returned based on the increase or decrease of the reagent discrimination information in each of the set layers.

Examples effects and effects

According to the intelligent management system for the experimental reagent provided by the embodiment, because each reagent bottle in the reagent cabinet has the reagent label containing the reagent identification information, and meanwhile, each reagent cabinet has the identification part for identifying the reagent label, all the existing reagent bottles in the reagent cabinet can be identified when the cabinet door is closed, and therefore the position of each reagent bottle can be effectively obtained and timely updated and stored in the reagent related information storage part. Meanwhile, the service side communication part receives a required reagent name input by the laboratory technician from the laboratory technician terminal, the reagent information retrieval and acquisition part retrieves the reagent related information storage part according to the required reagent name, and the service side communication part sends the extraction information acquired through retrieval to the laboratory technician terminal to enable the laboratory technician to go to the corresponding reagent cabinet and acquire the reagent in the corresponding placing layer. Therefore, the intelligent management system for the experimental reagent provided by the embodiment can accurately inform the experimenter of the position information of the reagent bottle required by the experimenter when the experimenter needs the position information, so that the experimenter can easily obtain the reagent in the experiment, and meanwhile, even if the reagent placing position in the reagent cabinet is disturbed due to the reasons of mistaken taking or reagent bottle placing position replacement and the like, the management of the reagent position cannot be influenced, and the original disordered management state of the experimental reagent is broken.

In addition, when returning the reagent, the laboratory technician can select a reagent cabinet at will and put the reagent that returns on arbitrary one places the layer, and does not worry about causing reagent management confusion to let the laboratory technician put into the professional experiment more with the energy that originally was used for managing the reagent, improve laboratory technician's work efficiency.

In this embodiment, the comparison determination unit can compare all the reagents in the reagent kit with the previously stored record, thereby comparing the taken or returned state of the reagent bottles in the reagent kit, and further update the state to the reagent-related information storage unit by the related information update unit. Therefore, through the experimental reagent intelligent management system of this embodiment, even the laboratory technician returns reagent to the reagent cabinet at will, also can accurately monitor the position of each reagent, made things convenient for the laboratory technician to take and return reagent.

Simultaneously, the request record storage part can be saved the cabinet number and the identifying information in the extraction information, the extraction record storage part can be saved the reagent discrimination information and the identifying information of the reagent to be returned after the reagent is extracted by the experimenter, therefore, the experimental reagent intelligent management system of the embodiment can only be recorded in the request record storage part or the extraction record storage part when the identity information of the experimenter, the experimenter can just rely on the personal identifying information to open the cabinet door of the reagent cabinet, the mode avoids some irrelevant personnel of experiments to open the reagent cabinet at will, avoid the occurrence that the reagent is damaged or stacked in disorder by being taken out in disorder.

In addition, in the present embodiment, since the identity search determination unit determines whether or not the identification information and the cabinet number match the predetermined reagent location position when the reagent is extracted by the laboratory worker, and the lock is released by the lock only when it is determined that the identification information and the cabinet number match the predetermined reagent location position, it is possible to avoid not only the problem that the laboratory worker uses the reagent without permission but also the problem that the laboratory worker cannot find the corresponding reagent because the laboratory worker mistakenly recognizes the reagent cabinet when extracting the reagent, and it is possible to manage reagent use in the laboratory.

In addition, in the present embodiment, when the reagent is returned by the laboratory technician, the identity search determination unit determines whether or not the identification information matches the record in the extracted record storage unit, and the lock is released by the lock unit only when it is determined that the identification information matches the record, so that when the laboratory technician needs to return the reagent, any one reagent cabinet can be opened directly by the identification information and the reagent can be returned, thereby further saving the labor of the laboratory technician in returning the reagent.

In addition, in the embodiment, the reagent information comparison determination part is arranged to determine whether the reagent taken out by the laboratory technician is consistent with the reagent to be extracted, and the warning device generates a warning prompt to the laboratory technician when the reagent taken out by the laboratory technician is inconsistent with the reagent to be extracted, so that the problem that the laboratory technician takes wrong reagents (for example, reagents with small differences due to similar colors) in a reagent cabinet due to errors and the like is avoided, the problems that the experiment is wrong due to reagent taking errors and the like can be further avoided, and finally, the management effect of the reagent in the laboratory is better improved.

In this embodiment, a reagent label based on a two-dimensional code is used to identify the reagent identification information of each reagent bottle, a camera arranged in the reagent cabinet is used to shoot the two-dimensional code, and a two-dimensional code identification part is used to identify the two-dimensional code in the image, so as to obtain the reagent identification information of each reagent bottle. Through such a mode, the laboratory can conveniently and accomplish the preparation of two-dimensional code label with low costs, for example through the mode of printing the two-dimensional code on the paper to the paper that will print the two-dimensional code is tailor and is pasted on the reagent bottle as the two-dimensional code label. However, such a method has a certain drawback that each two-dimensional code label must be provided with a position where a bottle cap of a reagent bottle or the like is easily photographed, and the two-dimensional code label is easily broken.

< modification example >

In this modification, the same reference numerals are given to the components having the same configurations as those of the embodiment, and the description thereof will be omitted.

The present modification provides an experimental reagent management system using an RFID tag as a reagent tag. Compared with the embodiment, the difference is the reagent label on the reagent bottle and the discriminating part in each layer placing layer, and the specific difference is as follows:

in this modification, the reagent label is an RFID label including reagent identification information, and can be attached to any position of the reagent bottle 151, such as a bottle cap, a bottle body, or a bottle bottom.

The determination unit is a reader capable of identifying RFID and is disposed at any position in the reagent tank 1 where normal sensing can be performed, for example, at the center of the top of each placement layer 15. In this case, the discrimination section can directly recognize the reagent discrimination information of all the reagent bottles 151 in each rack layer 15 when performing the discrimination.

When the laboratory technician takes out or returns the reagent and closes the cabinet door 12, once the sensing part 14 senses that the cabinet door 12 is closed, the main control chip 19 controls the locking part 13 to lock the cabinet door 12, controls the discriminating part 16 to discriminate all the reagent discriminating information corresponding to each placing layer 15, and further controls the reagent cabinet communication part 191 to send the discriminated reagent discriminating information and the corresponding layer number and cabinet number to the management server 2 for processing.

In contrast to the embodiment, in the present modification, the reagent identification information for identifying each reagent bottle by the RFID-based reagent label is used, and the reagent labels are identified by the RFID identifier provided in the reagent cabinet. In this way, although the manufacturing cost of the RFID tag is increased, the RFID tag can be easily installed at each position of the reagent bottle without affecting the normal identification of the reagent identification information, and the RFID tag is less likely to be damaged.

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 above-described embodiment, the reagents corresponding to the reagent discrimination information included in the extracted information are extracted by the laboratory technician. Alternatively, the laboratory technician may obtain only the reagent corresponding to a portion of the extracted information. At this time, the extracted information display screen further has a reagent selecting portion. Specifically, when the same reagent name in the reagent information storage part has a plurality of corresponding reagent identification information, the extraction information includes a plurality of reagent identification information, and after the extraction information is sent to the laboratory technician terminal, the extraction information display screen displays each reagent name and corresponding reagent position information in the extraction information on the reagent selecting part, so that the laboratory technician selects one or more reagents to view in detail, and at the moment, the extraction information display screen displays the reagent position information corresponding to the selection of the laboratory technician. Therefore, the intelligent management system for the experimental reagent can lead an experimenter to select the nearest reagent for extraction according to the displayed names of the reagents.

For example, in the above embodiment, the reagent-related information storage unit stores the reagent name, the reagent discrimination information, and the reagent position information, and the related data is stored in one storage unit. Alternatively, the reagent-related information may be stored separately, for example, by storing information such as the reagent identification information and the corresponding reagent name in the reagent information storage unit, and storing the reagent identification information and the reagent position information in the storage information storage unit. In this case, when updating the reagent position information, the relevant information can be updated directly to the storage information storage unit and the corresponding data items (i.e., the reagent discrimination information and the reagent position information) can be added or deleted.

For example, in the above-described embodiment, the identification information of the laboratory technician and the request and extraction record of the laboratory technician for the reagent are stored in the request record storage unit and the extraction record storage unit, and the identification information determination unit further determines whether or not the laboratory technician has the authority to open the reagent cabinet door. Alternatively, the management server can replace the request record storage unit and the extraction record storage unit with one identification information storage unit that stores identification information of all the laboratory laborers. When the main control chip controls the reagent cabinet communication part to send the identification information to the management server for determination, the identity retrieval determination part directly retrieves the identification information storage part according to the received identification information and determines whether the identification information contains the consistent identification information, if the identification information contains the consistent identification information, the service side control part controls the service side communication part to send a door opening permission information to the reagent cabinet, and if the identification information does not contain the consistent identification information, the identity retrieval determination part does not respond. Through such scheme, though can not carry out the management and control that the reagent cabinet opened the door according to the extraction demand of laboratory technician in a flexible way, but also can realize avoiding irrelevant personnel to open the effect of reagent cabinet.

Further, in the above-described embodiment, when determining whether or not the laboratory technician can open the cabinet door of the reagent cabinet, the identification search determination unit of the management server searches the request records and the extracted records in the request record storage unit and the extracted record storage unit to determine whether or not to unlock the cabinet door. Alternatively, all the request records and the extraction records can be periodically updated and stored in the main control chip by the management server, so that when the identification information of the experimenter is identified by the identity identification part, the main control chip executes the work corresponding to the identity retrieval judgment part to judge whether to unlock the cabinet door and allow the experimenter to extract or return the reagent. In addition, when identity judgment is performed only according to the identification information of all the laboratory experimenters in the laboratory, the identification information can be stored in the main control chip of the reagent cabinet, so that the main control chip can finish the identity judgment of the experimenters according to the identification information. In such a case, each reagent cabinet can independently determine the identity of the laboratory worker.

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

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. Alternatively, the identification information may be a password, two-dimensional code information corresponding to the identity of the experimenter, fingerprint information of the experimenter, or face information, and an identity recognition portion corresponding to the identification information, that is, a password input device, a two-dimensional code scanning device, a fingerprint recognition device, or a face recognition 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 above embodiment, when the identity search determination unit does not determine that there is matching identification information and a cabinet number, the management server does not respond. In other embodiments of the present invention, the service-side communication unit may send a warning signal to the corresponding reagent cabinet, so that the warning unit sends a warning to remind the experimenter.

For example, in the above-described embodiment, the reagent-related information storage unit stores only the reagent name and the reagent position information. In practical applications, the reagent-related information storage unit may also store other reagent-related information, such as reagent specifications and instructions.

For example, in the above embodiment, the warning portion is a warning light disposed on the front surface of the cabinet door. Alternatively, the warning portion may be replaced by an audible and visual alarm or other device with a prompt effect according to actual needs, and is disposed at a position where the reagent cabinet is easy to observe, such as the front surface and the top of the reagent cabinet.
