[0014] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0015] See also Figure 1-Figure 5 The present invention provides a technical solution: an intelligent reagent management system, comprising a centralized controller, the centralized controller is connected to a collection monitoring module, a human-computer interaction module, a reagent cabinet module, a network communication module and a face recognition module; the face recognition module comprises a camera 1 for performing face recognition on a user; the human interaction module comprises a touch screen 2, a voice interaction module 4 and a display screen 5; the collection monitoring module comprises an intelligent AI camera 6 for automatically identifying hand features, reagent kit features and reagent bottle features based on a deep learning algorithm, when the user's hand is not in the reagent kit 8 and unauthorized object features are identified, a voice prompt is immediately given, and a suspected cheating screen and / or video is sent to an administrator for secondary confirmation, and if it is determined that the user has cheated, a cheating disposal operation is performed; the network communication module comprises a wired network card and / or a wireless network card; When a user collects reagents, the intelligent reagent management system obtains real-time facial data and reads dynamic course information in real time; it determines whether the current user is a member of this class. If not, it prompts that the collection has failed. If the user is a member of this class, it determines whether the reagents are sufficient. If not, it prompts that the collection has failed; if the reagents are sufficient, the reagent cabinet 3 is popped out and the video is recorded simultaneously. After the user performs the collection operation, it determines whether the reagent remaining amount is correct and whether the user has cheated. If the reagent remaining amount is incorrect and / or the user has cheated, an abnormal collection prompt is given; if the reagent remaining amount is correct and the user has not cheated, the reagent cabinet 3 is closed.

[0016] In this embodiment, the composition and structure of the intelligent reagent management system are as follows: Figure 1 , 2 The reagent collection process is as follows: Figure 3As shown, the centralized controller is a single-chip microcomputer or an ARM chip that integrates various modules. The voice interaction module 4 includes a speaker and a microphone. The touch screen 2 displays the current available reagent information, the information of the person who collects the reagent, etc. The speaker is used to prompt the information of the person who collects the reagent and whether the number of reagents collected is correct; the display screen 5 is used to prompt the number of reagents to be collected. The intelligent reagent management system can be connected to the Internet and connected to the laboratory management system to obtain the class schedule and the information of the students (users) in the class, as well as the name and quantity of the reagents required for the course. The intelligent reagent management system has a face recognition camera 1, which can compare the acquired face data with the information of the students in the class. The reagent cabinet can be opened only after the comparison is successful to prevent irrelevant personnel from collecting reagents at will.

[0017] Each cabinet of the intelligent reagent management system has a detachable reagent kit 8. When replenishing, the teacher (administrator) only needs to take out the empty reagent kit 8 and replace it with a new one, without having to load the reagent bottles 7 one by one, which greatly reduces the teacher's workload.

[0018] Each cabinet of the intelligent reagent management system has a weighing function. When the reagent kit 8 is placed in, the reagent weight can be automatically obtained and the reagent quantity can be calculated based on the weight of a single reagent bottle. When the weight of the reagent kit 8 is lower than the critical value, the reagent cabinet 3 can sense that the reagent is insufficient and remotely remind the teacher to restock; after the student receives the reagent, the reagent cabinet 3 can sense whether the number of reagents received is correct. If the student takes too much reagent, a voice prompt will be given. If the student still does not put back the extra reagent, the intelligent reagent management system can remotely feedback the abnormal situation to the teacher, and the teacher can remotely communicate with the student through the speaker / microphone of the intelligent reagent management system to stop the behavior in time. On the one hand, this function improves the efficiency of the teacher's management of reagents, and the teacher does not need to regularly check whether the reagents are sufficient; on the other hand, it also avoids the safety risks caused by students taking too much reagents for other purposes.

[0019] Each reagent cabinet 3 of the intelligent reagent management system has a stepper motor 9 to drive the reagent cabinet 3 to open or close. After the student successfully scans the face for authentication, the reagent cabinet 3 will automatically open. After the reagents are collected, if the number of reagents collected is consistent with the required number and there is no cheating, the cabinet door will automatically close, avoiding the safety risks caused by the loss of reagents due to forgetting to close the cabinet door of the traditional reagent cabinet 3.

[0020] Each cabinet of the intelligent reagent management system has an LCD screen 5 to display the number of reagents that should be collected in the cabinet, reducing the risk of students collecting the wrong number of reagents. There is an intelligent AI camera 6 above each cabinet of the intelligent reagent management system. Every time the cabinet pops up, it will automatically capture the collection screen and automatically identify some cheating behaviors that the weighing system cannot identify, such as students putting other non-reagents into the reagent box 8, increasing the weight of the reagent box 8 and collecting more reagents. The intelligent AI camera 6 can further avoid the risk of students taking too many reagents.

[0021] In some embodiments, the voice interaction module 4 includes a speaker and a microphone.

[0022] In some embodiments, the reagent cabinet module includes a reagent cabinet 3, a containing chamber is formed inside the reagent cabinet 3, a display screen 5 is arranged on the side of the outside of the reagent cabinet 3 close to the user, and a stepper motor 9, a synchronous belt module 10 and a ball screw 11 are arranged on the side of the outside of the reagent cabinet 3 away from the user; a reagent reagent 8 is arranged in the containing chamber, a pressure sensor 12 is arranged under the reagent reagent 8 or the reagent cabinet 3, and a reagent bottle 7 is placed inside the reagent reagent 8; when the administrator performs a replenishment operation, the stepper motor 9 drives the synchronous belt module 10 to rotate, and the internal gear of the synchronous belt module 10 drives the ball screw 11 forward or backward.

[0023] In this embodiment, the structure of the reagent cabinet module is as follows: Figure 5 As shown, the reagent box 8 can accommodate 210 bottles of reagent bottles 7. When replenishing, the teacher takes out the empty reagent box 8 and replaces it with a new reagent box 8 (provided by the reagent manufacturer) filled with reagent bottles 7. Four pressure sensors 12 are set at the four corners of the bottom of the reagent cabinet 3 or the reagent box 8. When the reagent box 8 is put in, its weight can be accurately obtained (the sum of the data of the four pressure sensors 12, accurate to 0.1g), and the remaining amount can be calculated according to the weight information of the single reagent bottle set in the system.

[0024] In some embodiments, each time a door opening and closing command is executed, the stepper motor 9 moves a preset distance or a preset distance range.

[0025] In some embodiments, the reagent kit 8 is detachably disposed in the accommodating chamber. In some embodiments, when the preset conditions are met, the intelligent reagent management system issues a prompt of insufficient balance. After receiving the prompt of insufficient balance, the administrator performs a replenishment operation; at this time, the intelligent reagent management system pops up the reagent cabinet 3, and the administrator replaces the reagent kit 8 to complete the replenishment; the intelligent reagent management system closes the reagent cabinet 3 and performs a balance update operation.

[0026] In this embodiment, if Figure 4 As shown, the intelligent reagent management system can send the reagent remaining amount and reagent collection status to the teacher's mobile phone APP, which is convenient for the teacher to replenish the stock in time or deal with the problem of wrong collection of reagents. The teacher can also click on replenishment and change the information of reagent cabinet 3 in the mobile phone APP and interact with the intelligent reagent management system.

[0027] In some embodiments, the balance update operation includes updating the reagent name and the reagent weight.

[0028] In some embodiments, when the intelligent reagent management system issues an abnormal collection prompt, the administrator receives the abnormal information and performs remote abnormal processing operations.

[0029] Here is an actual example of use: Taking the experiment of "Effects of Drugs on Rabbit Arteries" as an example, this experiment requires the use of 9 reagents such as urethane and heparin saline. Intelligent reagent management system settings: After the intelligent reagent management system is connected to the network, teachers can bind the intelligent reagent management system for the first time on the mobile phone APP and set the basic information of 12 reagent cabinets, including the reagent information stored in each cabinet and the weight of each reagent bottle.

[0030] Reagent collection: The intelligent reagent management system obtains course and personnel information after being connected to the network and laboratory management system. After the student scans his face, the intelligent reagent management system automatically determines whether the student has the authority to collect reagents. If he does not have the authority, a voice prompt will be given. If he has the authority, the 9 cabinet doors storing the corresponding reagents will be opened; at the same time, the intelligent AI camera 6 above the cabinet door and the weighing module of the reagent cabinet 3 start working. After each reagent is collected, it is determined whether the amount of reagent collected is correct and whether there is cheating. If the amount of reagent collected is wrong or there is cheating, the intelligent reagent management system will immediately give a voice prompt and remind the teacher in the form of a message and (or) video. The teacher can communicate with the student remotely through the speaker / microphone 4 of the intelligent reagent management system to stop the wrong collection behavior in time; if the amount of reagent collected is correct and there is no cheating, the reagent cabinet 33 will be automatically closed under the drive of the stepper motor 98, without the need for the student to close it manually, to avoid forgetting to close the cabinet door and causing the reagent to be lost.

[0031] Reagent replenishment: After the intelligent reagent management system is bound to the mobile phone APP, the teacher will be prompted to replenish the reagent in the form of a message when the reagent is insufficient. When replenishing, the teacher needs to prepare a new reagent kit 8 in advance and click "Replenish" in the APP. The corresponding cabinet door will automatically open, and the teacher can take out the empty reagent kit 8 and refill it with a new one.

[0032] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
