< example one >

The embodiment relates to a non-fixed biological reagent freezing management cabinet, which is arranged in a laboratory and used for placing reagent bottles filled with various biological reagents needing to be frozen.

FIG. 1 is a schematic structural diagram of a non-fixed biological reagent freezing management cabinet according to an embodiment of the present invention.

As shown in fig. 1, the non-fixed biological reagent freezing management cabinet 100 includes a cabinet body 10, an electronic lock 20, a sensor 30, an identity recognizer 40, a tag recognizer 50, a temperature adjusting device 60, a voice prompt device 70, and a main control chip 80.

In this embodiment, the non-fixed biological reagent freezing management cabinet 100 is in communication connection with a management server in a laboratory through a communication network, so as to realize interaction (e.g., recording access status of a reagent) of relevant data (e.g., data such as identification information of a laboratory technician, recording information of a reagent, etc.) in the laboratory.

The cabinet body 10 includes a cabinet portion, three placing layers 121 for placing reagent bottles, a layer eaves 13 extending outward from an upper side layer of each placing layer 121, and a plurality of insulated cabinet doors 14 corresponding to each placing layer 121 and mounted on the cabinet portion.

The electronic lock 20 includes an electronic lock body 21 capable of being locked and unlocked according to an electrical signal of the main control chip 80, and a mating lock catch 22.

In this embodiment, the electronic lock body 21 is disposed at the edge (such as a door frame) of the front surface of the cabinet portion, which abuts against the insulated cabinet door 14; the lock 22 is disposed on the insulated cabinet door 14 and configured to cooperate with the electronic lock body 21, so that the insulated cabinet door 14 cannot be opened after the electronic lock 13 is locked.

The inductor 30 is disposed above the cabinet 10 and abuts the edge of the insulated cabinet door 14. In this embodiment, the sensor 30 is a conventional distance sensor or other sensors for sensing whether the insulated cabinet door 14 is closed.

The identity recognizer 40 is arranged on the surface of the heat-insulating cabinet door 14 and is used for recognizing the identity recognition information of the experimenter.

In this embodiment, the identification information is identification information that each experimenter has, and the identity of the experimenter can be directly and correspondingly determined through the identification information.

In this embodiment, the identification information may be the door opening information in a door opening card held by an experimenter, a password, two-dimensional code information corresponding to the identity of the experimenter, fingerprint information of the experimenter, face information, iris information or voiceprint information, and the identification device may be a card reader, a password input device, a two-dimensional code reader, a fingerprint acquirer, a face acquirer, an iris acquirer or a voiceprint acquirer corresponding to the identification information, so that the experimenter can operate the identification device 40 in a corresponding manner (i.e., perform operations such as swiping a card, inputting a password, scanning a two-dimensional code, verifying a fingerprint, shooting a face, acquiring an iris, acquiring a voiceprint, and the like), thereby allowing the identification device 40 to identify the identification information of the experimenter.

FIG. 2 is a schematic view showing the arrangement state of a reagent bottle in the embodiment of the present invention.

As shown in fig. 2, the interlayer plate 12 at the bottom of the placing layer 121 does not have any restriction structure for the reagent, and the reagent bottles 200 can be stored freely in the respective placing layers 121 without restriction, and each reagent bottle 200 is provided with one reagent label 201.

The label identifiers 50 are respectively arranged on the positions, close to the outer side surface of the insulated cabinet door 14, of the layer eaves 13 and used for identifying the reagent labels 201 of the reagent bottles 200 in the placing layers 121.

In this embodiment, the reagent label 201 includes reagent information (for example, the reagent information may include the number of each reagent bottle 200 and information about the name, dosage, and the like of the reagent in the corresponding reagent bottle 200), and the label identifier 50 can identify the reagent label 201 to obtain the corresponding reagent information. The reagent tag 201 is a low temperature resistant RFID tag that will work properly in the ultra-low temperature environment (i.e., -10 ℃ to-100 ℃) used to freeze biological reagents within the containment layer 121. The RFID tag may be optionally disposed (for example, by means of pasting or the like) at any position of the reagent bottle 200, and the RFID reader needs to be disposed on the layer eaves 13 (i.e., in the normal temperature environment outside the reagent cabinet 100) and ensure that the reading range of the RFID reader can cover all possible positions where the reagent bottle 200 may be disposed in the disposing layer 121.

In the present embodiment, the number of the label identifiers 50 corresponds to the number of the rack layers 121, and when the reagent labels 201 are identified, the label identifiers 50 can accurately identify all the reagent labels in the respective rack layers 121, thereby easily determining in which layer the laboratory technician has extracted or returned the biological reagent. Further, by numbering the set layers 121, the laboratory technician can further extract the reagent directly from the corresponding set layer 121 according to the record of the reagent position at the time of extraction.

FIG. 3 is a schematic diagram showing the installation position of the tag identifier according to the embodiment of the present invention, and FIG. 2 is a partial sectional view showing the structure of the non-fixed type biological reagent freezing management cabinet.

As shown in fig. 1 and 3, in the present embodiment, two tag identifiers 50 are embedded in the eaves 13 of the upper interlayer board provided on the corresponding placement layer 11, and are located at both ends (corresponding to the left and right sides) in the width direction of the interlayer board. Meanwhile, each label identifier 50 is located at the outer edge position of the interlayer plate, which corresponds to the outer surface position of the cabinet door 12, that is, a space with a heat preservation effect is defined between the heat preservation layer of the heat preservation cabinet door 14 and each interlayer plate of the placing layer 121, and the label identifier 50 is located outside the heat preservation space, so that the label identifier is not affected by low temperature in the space and can work normally.

FIG. 4 is a schematic diagram of the scope of a tag identifier of an embodiment of the present invention. Wherein, fig. 4(B) is a schematic range diagram in the width direction, fig. 4(a) is a schematic range diagram in the depth direction, and the broken lines in the diagrams each indicate the reading range of the tag identifier; in fig. 4(B), the insulated cabinet door 14 is omitted.

As shown in fig. 4(a), in the present embodiment, the reading range D of the tag identifier 50 in width is greater than one-half of the width L of the interlayer sheet 12 and smaller than the width L of the interlayer sheet 12. Since the label identifiers 50 are respectively located at both end positions of the interlayer plate 12, when the reagent bottles 200 are stored from a position close to one end of the interlayer plate (for example, put into the placing layer 121 from a position close to the left or right), only one label identifier 50 close to the reagent bottle 200 can read the reagent label 201 thereon, and when the reagent bottle 200 is taken and placed from a position close to the middle of the interlayer plate, both label identifiers 50 can read the sample label 201 thereon. For example, in fig. 4(a), a reagent bottle 200a is inserted from the right area, and its reagent label 201a is read only by the label identifier 50 on the right side during insertion; the reagent bottle 200b is inserted from the middle area, so that its reagent label 201a can be read by both label identifiers 50 simultaneously during the insertion process; the reagent bottle 200a is inserted from the left area, and the reagent label 201a thereof is read only by the left label identifier 50 during the insertion. Thus, the specimen rack control unit can determine the approximate position (left area, right area, or middle area) where the reagent bottle 200 is stored, based on the fact that the two label identifiers 50 read the biological labels.

In addition, as shown in fig. 4(B), the reading direction of the tag identifier 50 of the present embodiment is directed inward as viewed in the depth direction. Specifically, the tag identifier 50 of the present embodiment is a directional RFID reader, and the directional RFID reader 50 is installed to be slightly inclined inward, that is, the reading direction thereof is directed inward. Meanwhile, in the present embodiment, the layer 13 at the position of the tag identifier 50 is provided with an inward inclined slope portion 111A, so that the electromagnetic wave of the tag identifier 50 enters the placing layer to read the sample tag 201 on the reagent bottle 200 therein. For example, in fig. 4(B), once the cabinet door 14 is opened, the label identifier 50 can read the reagent label 201e on the reagent bottle 200e placed in the placing layer 121, but cannot read the reagent label 201d on the reagent bottle 200d that has not been placed in the placing layer 121. That is, since the reading directions of the label identifiers 50 are all facing inward, only the sample labels 201 on the reagent bottles 200 in the placing layer 121 will be read, and the reagent bottles 200 will not be read during the taking and placing process.

The process of reading the reagent label 201 by the label identifier 50 in this embodiment is as follows: the main control chip 80 controls the label recognizer 50 to continuously read and temporarily store the read sample discrimination information contained in the sample label 201 according to the opening condition of the cabinet door 14 sensed by the sensor 30 when the cabinet door 14 is opened, and outputs the last sample discrimination information, the layer number and the cabinet number of all the sample labels 201 read after the cabinet door 14 is closed, and at this time, the sample discrimination information corresponds to the biological sample 200 actually existing in the layer 121 when the scientific researchers finish taking and placing actions.

In addition, in this embodiment, the interlayer plate 12 further includes the metal interlayer 112, and the metal interlayer 112 provides a shielding effect, so that the label identifier 50 does not read the reagent label 201 on the reagent bottle 200 in the adjacent placement layer 121.

The temperature adjusting device 60 is disposed inside the cabinet 10 (e.g., disposed at the bottom of the cabinet in fig. 3) and is used for adjusting the ambient temperature in each placing layer 121 so as to maintain a low-temperature environment.

In this embodiment, the temperature adjusting device 60 is a conventional refrigerating device, and includes a refrigerant circuit penetrating the interlayer plate and used for refrigerating the placing layer 121, a compressor and a condenser connected to the refrigerant circuit, and a thermostat for controlling the operation of the compressor and the condenser.

In this embodiment, the temperature adjusting device 60 operates at a temperature of-10 ℃ to-100 ℃ to complete the freezing of the biological reagents stored in the reagent cabinet 100, and at such a temperature, especially below-30 ℃, general electronic components cannot normally operate, however, the label identifier 50 of this embodiment is disposed on the layer eaves 13, i.e., operates at normal temperature, and once the laboratory technician (or other related personnel) opens the cabinet door, the label identifier 50 can complete the identification of all the reagent labels 201 in the placement layer 121.

The voice prompt device 70 is disposed on the cabinet 10 (for example, disposed on a side surface of the cabinet 10 as shown in fig. 1) and is used for giving a warning prompt.

In this embodiment, the voice prompt device 70 includes an internal memory and a speaker, the internal memory stores preset prompt voice information in advance, and once the voice prompt device 70 receives a corresponding signal sent by the main control chip 80, the speaker sends a corresponding warning prompt according to the prompt voice information stored in the internal memory, so as to warn the experimenter that an error reagent is taken or put in.

In this embodiment, the internal memory stores the recognition error prompt voice message, the extraction error prompt voice message, the input error prompt voice message, and the like. The recognition error prompting voice is used for prompting by the voice prompting device 70 when receiving a recognition error signal sent by the main control chip 80, the extracted error prompting voice is used for prompting by the voice prompting device 70 when receiving an extracted error signal sent by the main control chip 80, and the put-in error prompting voice is used for prompting by the voice prompting device 70 when receiving a put-in error signal sent by the main control chip 80.

The voice guidance device 70 may also store other guidance voices, such as a door closing guidance voice for giving a warning when the door is not closed for a long time.

FIG. 5 is a functional block diagram of a freezing management cabinet for non-immobilized biological reagents according to an embodiment of the present invention.

The main control chip 80 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, the temperature adjusting device 60, and the voice prompt device 70.

In this embodiment, the main control chip 80 is a conventional microprocessor having a storage unit, a processing unit and a control unit, wherein the storage unit stores an experimenter information database, a reagent information database and an administrator information database, and the control unit generates a corresponding control signal through a preset program and controls other connected components. Specifically, the method comprises the following steps:

once the identification information of the experimenter is recognized by the identification device 40 and is sent to the main control chip 80, the main control chip 80 performs the authenticity judgment according to the received identification information.

In this embodiment, the laboratory member information database stores identification information of all laboratory members in the laboratory and corresponding available reagent information, where the available reagent information is reagent information of all reagents that each laboratory member is allowed to use. When the main control chip 80 determines whether the identity identification information received by the processing unit is consistent with the identity identification information in the laboratory technician information database, if so, the identity identification information is determined to be true, and the control unit sends an unlocking signal to the electronic lock 20, so that the electronic lock 20 unlocks the heat preservation cabinet door 14, and the laboratory technician can open the heat preservation cabinet door 14 to extract or return the reagent.

When the processing section determines that the voice is false, the control section transmits a recognition error signal to the voice presenting apparatus 70, and causes the voice presenting apparatus 70 to issue a recognition error presenting voice.

Once the sensor 30 senses that the insulation cabinet door 14 is opened and sends an opening sensing signal to the main control chip 80, the main control chip 80 sends a working signal to the label identifier 50, so that the label identifier 50 identifies the reagent information of all the reagent bottles on each corresponding layer.

In this embodiment, the reagent information database stores the reagent information of all the reagent bottles placed on each layer plate in the reagent cabinet. After the label identifier 50 identifies the reagent information, the control unit updates the reagent information database in the storage unit 71 based on the reagent information, so that the reagent information database is updated with the reagent information of the reagent bottles currently existing in the reagent cabinet. Meanwhile, the processing unit compares the pre-updated reagent information with the identified reagent information, so as to compare the missing or added reagent information (i.e. the missing or added reagent information).

In this case, the processing unit determines whether or not the available reagent information corresponding to the identification information contains information that matches the missing reagent information (or the new reagent information) based on the identification information and the missing reagent information (or the new reagent information) determined by the laboratory technician information storage unit. If it is determined that the reagent bottles do not contain the matching information, it indicates that the laboratory technician has extracted (or placed) the wrong reagent bottle, and the control unit sends an extraction error signal (or placement error signal) to the voice guidance device 70, so that the voice guidance device 70 sends an extraction error guidance voice (or placement error guidance voice) to warn the laboratory technician of the extraction (or placement) of the wrong reagent.

In addition, the administrator database stores management contact information for contacting an administrator, and when the extraction error signal (or the input error signal) is sent, the control unit also sends the content corresponding to the warning prompt and the identity identification information to an administrator terminal held by the administrator according to the management contact information, so that the administrator terminal displays the warning prompt and the corresponding laboratory technician identity to correspondingly process the warning prompt and the corresponding laboratory technician identity. The administrator terminal may be a computer device such as a computer or a mobile phone of the administrator, and the control unit may send the information to the administrator terminal through the communication network based on the management contact information (the management contact information may be contact information such as a telephone number, a mailbox, or an IP address of the administrator).

< 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.

In the case of the non-fixed type biological reagent freezing management cabinet of the second embodiment, the reading direction of the tag identifier 50 is directed outward, as compared with the case of the first embodiment.

Fig. 6 is a schematic range diagram of a tag identifier according to a second embodiment of the present invention. Wherein fig. 6(B) is a schematic view of a range in the width direction, fig. 6(a) is a schematic view of a range in the depth direction, and broken lines in the figures each indicate a reading range of the tag identifier; in addition, in fig. 6(B), the cabinet door 14 is omitted.

As shown in fig. 6(a), in the present embodiment, the reading range D of the tag identifier 50 in width is greater than one-half of the width L of the interlayer sheet 12 and smaller than the width L. Since the label identifiers 50 are respectively located at both end positions of the interlayer plate 12, when the biological reagent 200 is stored from a position close to one end of the interlayer plate 12 (for example, put into the placing layer 121 from a position close to the left or right), only one of the label identifiers 50 close to the biological reagent 200 can read the reagent label 201 thereon, and when the biological reagent 200 is taken and placed from a position close to the middle of the interlayer plate 12, both of the label identifiers 50 can read the reagent label 201 thereon. For example, in fig. 6(a), the biological reagent 200a is put in from the right area, and the biological label 201a thereof is read only by the label identifier 50 on the right side during the putting in; the bio-agent 200b is put in from the middle area, so that its bio-tag 201a can be read by two tag identifiers 50 at the same time during the putting in process; the biological reagent 200a is inserted from the left area, and the biological label 201a thereof is read only by the left label identifier 50 during the insertion. Thus, the specimen chamber controller can determine the approximate position (left area, right area, or middle area) where the biological reagent 200 is stored, based on the fact that the two tag identifiers 50 read the biological tags.

In addition, as shown in fig. 6(B), the reading direction of the label identifier 50 in the present embodiment is not directed inward (i.e., is not directed toward the inside of the setting layer 121) when viewed from the depth direction, so that the label identifier 50 cannot read the reagent label 201 on the biological reagent 200 in the setting layer 121 regardless of the opened or closed state of the cabinet door 14.

Specifically, the tag identifier 50 of the second embodiment is a directional RFID reader, and the directional RFID reader is installed slightly obliquely outward, that is, the reading direction of the directional RFID reader faces outward, so that the reagent tag 201 is read only during the picking and placing process. For example, in fig. 6(B), once the cabinet door 14 is opened, the tag identifier 50 can read the bio-tag 201d on the bio-reagent 200d being put in, but cannot read the bio-tag 201e on the bio-reagent 200e already positioned in the setting layer 121. That is, since the reading directions of the label identifiers 50 are all facing outward, the reagent labels 201 on the biological reagents 200 in the placing layer 121 cannot be read, and the biological reagents 200 can only pass through the reading area of the label identifiers 50 in the taking and placing process, so that the reagent labels 201 thereon are read.

< modification example >

In this modification, 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 modification provides a non-fixed biological reagent freezing management cabinet which displays warning prompts through a display device. Compared with the first embodiment, the difference is that the voice prompt device 70 on the cabinet 10 is replaced by a display device, and the specific differences are as follows:

the display device is arranged on the cabinet body 10 (for example, arranged on the outer surface of the insulated cabinet door 14) and is used for displaying warning prompts.

In this embodiment, the display device includes an internal memory and a display, the internal memory stores a preset prompt display picture in advance, and once the display device receives a corresponding signal sent by the main control chip 80, the display sends a corresponding warning prompt according to the prompt display picture stored in the internal memory, so as to warn the experimenter that an incorrect reagent is extracted or put in.

In this embodiment, the internal memory stores an identification error presentation display screen, an extraction error presentation display screen, a placement error presentation display screen, and the like. The identification error prompt display picture is used for prompting by the display device when receiving an identification error signal sent by the main control chip 80, the extraction error prompt display picture is used for prompting by the display device when receiving an extraction error signal sent by the main control chip 80, and the placement error prompt display picture is used for prompting by the display device when receiving a placement error signal sent by the main control chip 80.

Still owing to place every and place the outside extension of layer interlayer board of layer upside and form the layer eaves, further respectively on each layer eaves be close to the position in the heat preservation cabinet door outside and set up the label recognizer, consequently open the heat preservation cabinet door and take out or put into the biological reagent who is equipped with the reagent label, thereby the label recognizer just can accomplish the discernment to the reagent label and confirm biological reagent's access state easily, and simultaneously, because the label recognizer sets up in the outside of heat preservation cabinet door, expose promptly in the normal atmospheric temperature, consequently even the internal need of cabinet sets up ultra-low temperature and preserves biological reagent and also can not influence the label recognizer of cabinet external portion, thereby normally monitor each bottle biological reagent in the reagent cabinet. Through the non-fixed biological reagent freezing management cabinet of this embodiment, the laboratory technician can place the reagent bottle in arbitrary layer of placing at will and need not worry about producing the management confusion of reagent bottle.

In addition, still be provided with the electronic lock that can lock the cabinet door among the reagent cabinet, the sensor of response cabinet door switching and the identity recognizer that the identity discerned to the laboratory technician, consequently can judge just let the laboratory technician open the cabinet door when meeting the requirements to the laboratory technician's identity before the reagent cabinet is opened, the security of non-fixed biological reagent management cabinet that freezes 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.

In addition, in the above embodiment, since the low temperature environment set in the cabinet is an ultra-low temperature environment of-30 ℃ to-100 ℃, RFID tags capable of adapting to the ultra-low temperature environment are adopted, and the RFID tags can be normally identified by the RFID reader in the ultra-low temperature environment.

Further, in the above embodiment, since the two RFID readers are respectively disposed at the two ends of each layer eave in the length direction, and the reading range of the RFID readers is set to be larger than one-half of the width of the interlayer plate and smaller than the width of the interlayer plate, the reagent tag of the biological reagent in each placing layer can be identified by the two RFID readers left and right, so that when the condition that the biological reagent in the placing layer is extracted or returned is judged, the biological reagent can be easily judged to be placed on the left side, the right side or the middle of the placing layer, the reagent cabinet of the embodiment is further convenient for accurately managing the position where each biological reagent is stored, an experimenter can take the biological reagent more quickly according to the approximate position, the time for opening the cabinet door is reduced, and the low-temperature environment in the placing layer can be maintained stable more easily.

In the second embodiment, because the reading direction of the RFID reader faces outward, the sample tags in the corresponding placing layers cannot be read, and meanwhile, the interlayer plate is provided with the metal interlayer, so that the RFID reader can be prevented from reading the sample tags in the adjacent placing layers, therefore, misreading can be prevented, and the accuracy of reagent access judgment is improved.

In addition, in the embodiment, the non-fixed biological reagent freezing management cabinet disclosed by the utility model is used for managing the reagent, and after the reagent is extracted by a laboratory technician, the reagent cabinet can automatically obtain the extraction record of the laboratory technician according to the identification information of the laboratory technician and the discrimination information of the reagent, so that additional registration personnel and registration steps are avoided.

In addition, in the above-described embodiment, since the reagent label is an RFID label, the RFID label can be easily set at each position of the reagent bottle, and the reagent information of the reagent bottle in each set layer can be easily determined by reading the RFID label of the reagent bottle by an RFID reader.

In addition, in the above embodiment, the identity recognizer may be adjusted to be a card reader, a password input device, a two-dimensional code reader, a fingerprint collector, a face collector, an iris collector, a voiceprint collector, or the like according to actual needs of the laboratory, so as to adapt to the original laboratory management, and better enable the non-fixed biological reagent freezing management cabinet of the present invention to be applied to each laboratory.

In addition, in the above embodiment, the voice prompt device (or the display device) can perform corresponding warning prompt to the experimenter through voice (or pictures), so as to better realize the function of the non-fixed biological reagent freezing management cabinet. For example, when a laboratory technician takes out wrong reagents (for example, reagents with smaller differences due to similar colors) in a reagent cabinet due to errors and the like, or the laboratory technician takes out reagents which are not in the authority of the laboratory technician, an extraction error prompt voice prompt can be generated to prompt the laboratory technician, so that the problems of errors in the experiment due to reagent taking errors, illegal reagent extraction by the laboratory technician and the like can be further avoided, and the management effect of the reagent in a laboratory is finally better improved.

In addition, in the embodiment, the main control chip completes the authenticity judgment of the identity of the laboratory worker and the judgment of the reagent information according to the storage unit, the judgment unit and the control unit which are contained in the main control chip, so that the monitoring of the access state of the reagent is completed only by the non-fixed biological reagent freezing management cabinet, and the main control chip is conveniently applied to facilities such as a small laboratory which is not provided with a management server.

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 first embodiment, the tag identifier is a directional RFID reader, which is mounted on the layer eaves and the reading direction of which is toward the inside; in the second embodiment, the reading direction of the tag identifier faces outward. In other schemes, a shielding layer may be disposed at an outer side position of each directional RFID reader, so as to prevent the reading range of the RFID reader from extending outward too much, in this case, the reading range of each RFID reader is only equivalent to an area vertically below the reading range, so that repeated reading (for example, the biological sample is held by a scientific researcher during taking and placing or temporarily placed on a taking and placing tray and thus located at the position) when the biological sample is located at the outer side position close to the placing layer 11 can be avoided, and thus the moving condition of the sample label in and out of the placing layer can be read more accurately.

For example, in the first embodiment, the voice prompt device sends out a corresponding warning prompt voice according to the signal of the main control chip, and in the third embodiment, the display device displays a corresponding warning prompt picture according to the signal of the main control chip. However, in other embodiments of the present invention, the non-immobilized biological reagent freezing management cabinet can also be provided with a voice prompt device and a display device at the same time, and the main control chip sends corresponding signals to the voice prompt device and the display device at the same time, so that both devices send out a warning to warn the experimenter, thereby better avoiding that the experimenter extracts (or puts) a wrong reagent or extracts (or puts) a reagent which is not in the authority limit of the experimenter.

For example, in the above embodiment, the authenticity determination and the reagent determination performed by the main control chip are performed by the own storage unit and determination unit. In other schemes, the reagent cabinet can be in communication connection with a management server, the main control chip sends the received identity identification information to the management server for judgment when the authenticity is judged, and sends the identified reagent information to the management server for updating and comparison judgment when the reagent judgment operation is carried out, so that unified monitoring and management of the information received by the reagent cabinet are facilitated when a plurality of reagent cabinets are arranged in a laboratory.

For example, in the above embodiment, two symmetrically disposed determination portions are provided for each of the placement layers in the reagent tank, and the rough position information is the left side and the right side corresponding to the positions of the determination portions, respectively. In other aspects of the utility model, each placing layer can be correspondingly provided with more RFID readers and is uniformly arranged in the placing layer, and the number of corresponding rough positions is further increased, so that the rough position information is more accurate, and the position of the reagent bottle on the placing layer can be more accurately judged.

In addition, in the above embodiment, two determination portions are provided on the layer eaves corresponding to each layer of the placement layer, and the range of the determination portions can cover the entire placement layer. In other schemes of the utility model, in order to facilitate the discrimination part to discriminate the whole placement layer, a form of a directional RFID reader can be adopted, the directional RFID reader is installed slightly obliquely outward, i.e. the reading direction of the directional RFID reader faces inward, and meanwhile, an inward inclined slope part can be arranged on the layer brim at the position of the RFID reader, so that electromagnetic waves of the RFID reader enter the placement layer to read the sample label on the biological sample in the placement layer.

Further, when in actual use, more discrimination parts can be correspondingly arranged under each layer of eave according to actual requirements, so that the accuracy of discrimination of rough position information is improved.

For another example, in the above embodiment, two tag identifiers are corresponding to each placement layer. However, in other embodiments of the present invention, there may be one tag identifier corresponding to each placement layer, and in this case, the read range of the RFID reader needs to cover the entire interlayer board, so as to complete the identification of all reagent tags in the placement layer. Furthermore, the number of the tag identifiers corresponding to each placing layer can be multiple, the reading range of the RFID reader of each layer pair needs to be reduced in an equal proportion, and the position of the biological reagent in each layer can be accurately judged.

For example, in the above embodiments, the electronic lock body is disposed on the cabinet portion, and the lock catch is disposed on the cabinet door. In other embodiments of the present invention, the electronic lock body and the lock catch may be disposed oppositely, that is, the electronic lock body is disposed on the cabinet door, and the lock catch is disposed on the cabinet portion.

For example, in the above-described embodiment, the temperature adjustment device includes a refrigerant circuit penetrating each of the placed layers and a compressor, and in other embodiments, the temperature adjustment device may also be other conventional refrigeration devices.
