[0020] Figure 1It is a schematic flow chart of the control method of the medical consumables cabinet provided by the first embodiment of the present invention; Figure 2 It is a schematic structural diagram of the control system of the medical consumables cabinet provided by the second embodiment of the present invention. Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figure 1 , the first embodiment of the present invention provides a control method for a medical consumables cabinet, including the following steps: S11, obtain the consumable weight information, consumable volume information, consumable identification label and the status of the cabinet door of the consumables cabinet.

[0023] S12, judge the opening and closing status of the cabinet door of the consumables cabinet according to the status of the cabinet door of the consumables cabinet.

[0024] S13, when it is determined that the cabinet door of the consumables cabinet is closed, perform a matching calculation between the consumable identification label and the standard label in the preset standard library to obtain a label matching degree.

[0025] S14, when the label matching degree is greater than or equal to the preset matching degree threshold, perform a consistency judgment between the consumable identification label and the traceability label in the traceability database.

[0026] S15, when the consumable identification label is consistent with the traceability label, perform a calculation of the consumable change amount according to the consumable weight information and the consumable volume information to obtain the consumable change amount.

[0027] S16, perform a credibility calculation on the consumable change amount to obtain a variable credibility. When the variable credibility is greater than the preset credibility threshold, record the consumable change amount.

[0028] It should be noted that a medical consumables cabinet is a device used to store, manage and distribute medical consumables, and is applied to medical institutions such as hospitals, clinics, and laboratories to store various medical supplies, such as syringes, infusion sets, masks, gloves, gauze, disinfectants, etc. These consumables cabinets have a storage function and can record the usage situation, inventory quantity and expiration date of consumables through effective methods, helping hospitals achieve precise management of consumables and reducing waste and mis-discovery phenomena.

[0029] For the convenience of understanding the present invention, some preferred embodiments of the present invention will be further described below.

[0030] In step S11, obtain the consumable weight information, consumable volume information, consumable identification label and the state of the consumable cabinet door of the consumable cabinet.

[0031] Specifically, the weight information of the consumables can be measured by an electronic weighing device. A group of high-precision load sensors or pressure sensors can be installed at the bottom of the medical consumable cabinet or inside the consumable cabinet. When consumables are placed or taken out, the sensors monitor and calculate the weight change of the consumables in the bin in real time. These sensors convert the pressure change into an electrical signal, which is then transmitted to the control module through a data acquisition system, and then the weight of the consumables is calculated. In this way, the system can accurately record the weight change of the consumables, so as to effectively track the access situation of each consumable.

[0032] Specifically, the volume information of the consumables can be measured by an ultrasonic sensor or a laser rangefinder. The ultrasonic sensor uses the principle of sound wave reflection to measure the height, width and depth of the consumables, so as to calculate the volume of the consumables. In some more complex systems, the laser rangefinder can accurately calculate the three-dimensional space occupancy of the consumables by emitting a laser beam and measuring the time it takes to reflect back. In addition, three-dimensional scanning technology can also be used. This technology can scan the consumables from multiple angles and convert the scanning results into a three-dimensional data model of the consumables, and then obtain accurate volume information. No matter which technology is used, these sensors and devices can efficiently and accurately calculate the volume of the consumables, ensuring that the system has a clear record of the storage space of each consumable.

[0033] Specifically, in terms of consumable identification, the consumable identification label can adopt radio frequency identification (RFID) technology or barcode technology. The RFID technology installs a small electronic tag on the consumables, and each tag contains a unique identifier. When the consumables are placed or taken out, the RFID reader can quickly read the information in the tag to identify the information of the consumables. In contrast, barcodes or two-dimensional codes need to be read by a scanner. The above technologies ensure that each consumable can be uniquely identified and recorded, so as to realize real-time tracking of consumable information. The consumable identification label can not only ensure the correct identification of the consumable information, but also compare with the label in the standard library to avoid misoperation or incorrect recording.

[0034] Specifically, the opening and closing state of the consumable cabinet door can be monitored by the access control sensor of the consumable cabinet door. Exemplarily, common technologies include magnetic switch sensors, infrared sensors, and photoelectric sensors. The magnetic switch sensor determines whether the consumable cabinet is in the open or closed state by detecting the opening and closing of the door. The infrared sensor determines the opening and closing state of the consumable cabinet door by emitting and receiving infrared light beams. The sensor transmits the status information of the consumable cabinet door to the system in real time, and the system determines whether to record the access operation of the consumables according to the status of the consumable cabinet door. When the consumable cabinet door is in the open state, the system does not record the data of the consumable identification label, avoiding misrecording or missing recording during the process of taking and placing consumables, thereby improving the accuracy of consumable management.

[0035] In step S12, according to the state of the consumable cabinet door, determine the opening and closing state of the consumable cabinet door.

[0036] It is worth noting that the opening and closing state of the consumable cabinet door directly affects the storage and retrieval behavior of the consumables. When the warehouse door is in the closed state, it means that the consumables are in a stable storage state, and the system can safely record the storage and retrieval information of the consumables. In this case, the reading of the consumable identification label can accurately reflect the storage situation of the consumables because there is no external interference (such as an operator taking or storing items). By detecting the opening and closing state of the warehouse door, the system can ensure that the storage changes of the consumables are recorded only when the warehouse door is closed. In this way, the storage record of the consumables is updated only when the access operation of the consumables is completed, avoiding recording errors or missing records caused by incomplete operations when the warehouse door is open.

[0037] When the consumable cabinet door is in the open state, the system does not immediately collect the data of the consumable identification label. This is because when the warehouse door is open, the consumables may be being taken out or stored, and the data of the consumable identification label at this time will be interfered. For example, during the process of taking items, the reading of the consumable label will be interrupted, or during the process of storing consumables, other consumables in the warehouse will be misidentified. Therefore, in the present invention, recording data when the warehouse door is open is avoided, ensuring that the change record of the consumables is only carried out when the consumable cabinet door is closed, so as to confirm and record after the operation is completed.

[0038] Generally speaking, the reasons for determining the opening and closing state of the consumable cabinet door are mainly as follows: to ensure the accurate collection of the data of the consumable identification label, to avoid interference caused by taking or storing operations when the warehouse door is open, to avoid recording errors or missing records, and at the same time to enhance the safety of system operation and the accuracy of management.

[0039] In step S13, when it is determined that the consumable cabinet door is closed, match the consumable identification label with the standard label in the preset standard library to obtain a label matching degree.

[0040] Preferably, when it is determined that the consumable cabinet door is closed, the consumable identification label is matched with the standard label in the preset standard library to obtain a label matching degree, including: Calculate the label matching degree through the following formula:

[0041] In the formula, is the label matching degree; is the th eigenvalue in the standard label; is the th eigenvalue in the consumable identification label; is the number of eigenvalues.

[0042] Specifically, when it is determined that the consumable cabinet door is closed, the system matches and calculates the consumable identification label with the standard label in the preset standard library to determine whether the consumable meets the predetermined standard information. This matching process is a step for the system to ensure the accurate identity of the consumable.

[0043] Specifically, the calculation method in the formula is based on the matching degree of the standard label and the consumable identification label in terms of eigenvalues. Each label contains multiple eigenvalues, and these eigenvalues represent different dimensions of information in the label. Exemplarily, they include the type, size, and production batch number of the consumable. To compare the similarity of two labels, it is necessary to first judge their matching degree by comparing each pair of corresponding eigenvalues. Among them, represents taking the minimum value between the th eigenvalues of the standard label and the consumable identification label. If the two eigenvalues are not exactly the same, taking the smaller value can reduce the influence of the inconsistency on the final result. In this way, the system gives a certain margin to partially similar eigenvalues. represents taking the maximum value between the th eigenvalues of the standard label and the consumable identification label. The maximum value reflects the maximum manifestation of the characteristics between the standard label and the consumable identification label, and gives the maximum possible matching degree between them. In this way, the system ensures that the matching degree is higher only when the characteristic gap between the two labels is small or consistent. By adding the minimum value and the maximum value, the relative consistency of each pair of eigenvalues is calculated, and then these values are added together to finally obtain the matching degree of the entire label. The closer this matching degree M is to 1, the better the eigenvalues of the two labels match, and the higher the accuracy of the consumable identity recognition.

[0044] It should be noted that the calculation of the label matching degree can effectively reduce the incorrect matching caused by the slight differences in the label feature values (such as production batch numbers or dimensional errors). By normalizing the difference between the minimum value and the maximum value, the system can match the consumables with the standard label within a certain tolerance range, ensuring more accurate storage and management records of the consumables.

[0045] Preferably, the judging of the opening and closing state of the consumable cabinet door according to the state of the consumable cabinet door further includes: When it is determined that the consumable cabinet door is opened, according to the consumable weight information and the consumable volume information, calculate the consumable change amount to obtain the consumable change amount; Calculate the credibility of the consumable change amount to obtain the variable credibility. When the variable credibility is greater than the preset credibility threshold, record the consumable change amount.

[0046] It should be noted that in the present invention, the credibility is calculated based on the misrecording probability of Bayesian inference. The Bayesian inference misrecording probability assessment is a method based on Bayes' theorem, which is used to evaluate the probability of misrecording, missing recording or incorrect recording during the access process of consumables. This method uses the known prior probability and the newly observed data to calculate the posterior probability of misrecording through conditional probability. Specifically, is the variable credibility, which is the system's assessment of whether the change amount of the consumables is credible under the given observed change amount of the consumables. Exemplarily, the method for determining the credibility threshold can be based on statistical analysis of historical data. By analyzing the historical data, the range of the change amount of the consumables under normal circumstances can be statistically obtained, and a credibility threshold can be set; or based on a machine learning model, use machine learning algorithms to train a model, based on historical records (such as features such as consumable change amount, label matching degree, etc.), predict whether the change amount is credible, and select a suitable threshold from it.

[0047] It should be noted that the open state of the consumable cabinet door indicates that the operation of the consumables is about to occur or is occurring. Therefore, the system can directly enter the calculation process of the consumable change amount. This design is based on the premise that before the consumable cabinet door is opened, the system has completed the calculation of the matching degree between the consumable identification label and the label in the preset standard library and the consistency judgment with the traceability label. Before the warehouse door is opened, the system has verified the identity information and historical records of the consumables in the current warehouse, ensuring that the consumables match the information registered in the database and eliminating the identity uncertainty that may cause errors during the access process of the consumables. Therefore, once the warehouse door is opened, the system can directly enter the calculation of the change in the state of the consumables without verifying the identity of the consumables again, and obtain the consumable change amount.

[0048] It should be noted that the calculation of the consumable change amount and the credibility calculation performed here are the calculations for the subsequent steps.

[0049] In step S14, when the label matching degree is greater than or equal to a preset matching degree threshold, the consistency between the consumable identification label and the traceability label in the traceability database is judged.

[0050] Preferably, when the label matching degree is greater than or equal to a preset matching degree threshold, judging the consistency between the consumable identification label and the traceability label in the traceability database includes: The traceability label is obtained from the consumable label input by the operator when the consumable is put into storage and stored in the traceability database; wherein, the consumable label includes consumable information, operator identity information and operation type.

[0051] Specifically, when the consumable identification label is matched with the label in the standard library, if the matching degree is greater than or equal to the threshold set by the system, it means that there is a high consistency between the consumable identification label and the data in the standard library. This step ensures that there are no significant deviations or errors in the consumable identification process. However, the preliminary matching of the label alone is not sufficient to fully confirm the identity and storage status of the consumable. Therefore, the system further compares the consistency between the consumable identification label and the traceability label in the traceability database to comprehensively verify the correctness and integrity of the consumable information.

[0052] It should be noted that the matching degree calculated in the above step is a numerical value within the range of [0, 1]. The closer the value is to 1, the more matching the two labels are. A matching degree threshold needs to be set. Exemplarily, the threshold is set to 0.8, indicating that when the label matching degree is greater than or equal to 0.8, it is considered that the consumable label matches the standard label. In a feasible way, the matching degree threshold can be obtained through statistical analysis of historical data. First, the matching degree between the consumable identification label and the standard label can be calculated through historical data. For example, by collecting correct matching results, the matching degree distribution can be calculated. By calculating the correct matching degree distribution (such as calculating the mean and standard deviation), a threshold based on the distribution can be set. For example, if the mean of the matching degree is 0.85 and the standard deviation is 0.05, the threshold can be set to 0.8 or 0.9 (according to the fault tolerance requirement).

[0053] Specifically, the traceability label is the label information input by the operator when the consumables are warehoused and stored in the traceability database. The traceability label contains the basic characteristic information of the consumables, such as the name, batch number, and specification of the consumables, and also includes important record information related to the storage and transfer of the consumables, the operator's identity information, and the operation type. Exemplarily, the consumable information may include the type, batch number, manufacturer, and production date of the consumables; the operator's identity information may include the identification information of the staff responsible for warehousing the consumables or the system operator; the operation type may include indicating the type of operation process of the consumables, such as the first warehousing, inventory update, or removal from the warehouse of the consumables.

[0054] Specifically, in the consistency judgment, the system retrieves the traceability label corresponding to the current consumable identification label from the traceability database and compares the key information item by item. Specifically, the system checks whether the consumable identification, operator record, and operation type in the identification label are consistent with the traceability label. If the comparison results are completely consistent, the system can confirm that the current status of the consumable matches the historical record, indicating that the change of the consumable meets the expectation.

[0055] Preferably, after judging the consistency between the consumable identification label and the traceability label in the traceability database when the label matching degree is greater than or equal to the preset matching degree threshold, it further includes: When the consumable identification label is inconsistent with the traceability label, an alarm operation is performed to enable the management personnel to check the data and correct the data.

[0056] Specifically, the core purpose of this consistency judgment is to ensure that there is no information mismatch or recording error caused by human misoperation during the access process of the consumables. For example, if a certain consumable label is marked as "high-value consumable" when warehoused, but fails to pass the consistency comparison during the access process, the system can trigger an exception handling mechanism, perform an alarm operation, and prompt the operator to check or correct the data.

[0057] In step S15, when the consumable identification label is consistent with the traceability label, the consumable change amount is calculated based on the consumable weight information and the consumable volume information to obtain the consumable change amount.

[0058] The calculating the consumable change amount based on the consumable weight information and the consumable volume information when the consumable identification label is consistent with the traceability label includes: The consumable change amount is calculated by the following formula:

[0059] In the formula, is the consumable change amount; is the weight weighting factor; is the volume weight factor; is the current weight of the consumable; is the historical weight of the consumable; is the density of the consumable; is the current volume of the consumable; is the historical volume of the consumable.

[0060] Specifically, is the change amount of the consumable, which is the actual change amount that occurs during the access process of the consumable, and is used to determine whether the consumable is stored or taken out and the quantity of the change. is the weight weight factor, which is used to adjust the importance of weight in the overall calculation of consumable changes. Different types of consumables have different sensitivities to weight changes. The value of can be dynamically set according to the characteristics of the consumable. For example, for consumables with a relatively heavy mass and a small volume (such as metal consumables), the value of can be set relatively high. is the volume weight factor, corresponding to the weight weight factor, which is used to adjust the impact of volume change on the overall change amount calculation. For consumables with a large volume (such as gauze, disinfectant solution), the value of can be set even higher. is the current weight of the consumable, is the historical weight of the consumable, and the difference between the two reflects the increase or decrease of the consumable weight. is the density of the consumable. It should be noted that the consumable density is pre-stored data and is an important parameter for converting volume changes into corresponding masses, especially in liquids or other consumables with obvious volume differences. The accuracy of is crucial. is the current volume of the consumable, is the historical volume of the consumable, and the difference between the two represents the increase or decrease of the consumable volume.

[0061] It should be noted that the system can control the impact of weight and volume on the calculation result of the change amount through the weight factors and This weight adjustment mechanism allows the system to automatically adapt according to different types of consumables. For example, for liquid consumables, volume change is a more direct change indicator, so the weight of can be increased; while for solid or heavier consumables (such as surgical instruments), weight change is more decisive, the weight of will be relatively large.

[0062] In step S16, calculate the credibility of the consumable change amount to obtain the variable credibility. When the variable credibility is greater than the preset credibility threshold, record the consumable change amount.

[0063] Preferably, calculating the credibility of the consumable change amount to obtain the variable credibility includes: Calculating the variable credibility through the following formula:

[0064] In the formula, is the variable credibility; is the prior probability of the consumable change amount; is the conditional probability of the consumable change amount; is the probability of the consumable change amount being abnormal; is the probability that the consumable change amount meets the preset standard when the consumable change amount is abnormal.

[0065] It should be noted that the Bayesian inference misrecording probability assessment is a method based on Bayes' theorem, which is used to evaluate the probability of misrecording, missing recording, or incorrect recording during the process of accessing consumables. This method uses the known prior probability and newly observed data to calculate the posterior probability of misrecording through conditional probability. Specifically, the core formula of Bayes' theorem is: , where is the probability of event A occurring after event B occurs, called the posterior probability. is the probability of observing event B under the condition that event A occurs. is the prior probability of event A occurring, that is, the preliminary judgment of the event occurring before any data is observed. is the probability of event B occurring.

[0066] In the present invention, Bayesian inference can be used to evaluate whether misrecording may occur in the current access operation according to data such as consumable labels, weight, and volume changes. The system will use historical data (prior probability) and real-time collected data (observed evidence) to calculate the posterior probability of misrecording. Specifically, is the variable credibility, which is the system's evaluation of whether the change amount is credible given the observed consumable change amount. is the prior probability of the consumable change amount, which is the system's preliminary judgment of the normal change of the consumable access operation before observing the current change amount, based on historical data statistics. is the conditional probability of the consumable change amount, which represents the probability of observing the current change amount when the consumable change amount is normal. is the probability of the consumable change amount being abnormal, which represents the possibility of the change amount being abnormal due to misoperation, equipment failure, or external interference during the operation process. is the probability that the consumable change amount meets the preset standard when the consumable change amount is abnormal. It represents the probability of observing the change amount meeting the system preset standard when the consumable change amount is abnormal.

[0067] It should be noted that the core purpose of credibility calculation is to evaluate the authenticity of the consumable change amount based on historical data and current observation results during the real-time data collection process. Due to environmental interference, sensor errors, or operator mistakes during the access of consumables, directly recording the unverified change amount will lead to inaccurate data. Therefore, through credibility calculation, the system can dynamically determine whether the change amount is credible based on prior knowledge and current data, and decide whether to include this change amount in the formal record accordingly. Among them, the prior probability is the system's preliminary assessment of normal consumable changes, which can be obtained through historical data statistics. For example, if there is approximately a 90% probability of weight or volume change for a certain consumable during normal access operations, the prior probability is 0.9.

[0068] Specifically, first, the system determines the prior probability based on historical data and real-time monitored data, and obtains the abnormal probability 、 、and ; then, substitute into the formula to calculate the variable credibility; finally, the system compares this credibility with a preset credibility threshold. If the variable credibility is greater than the preset credibility threshold, it is considered that the currently observed change amount is credible and is formally recorded.

[0069] The following takes a relatively common scenario as an example to describe the working process of the present invention. The working process is as follows: When the system is working, it will first obtain data such as the weight, volume, consumable identification label, and the opening and closing status of the consumable cabinet door in the consumable cabinet in real time. These data are the basis for recording the removal or storage operations of consumables. When the system detects that the consumable cabinet door is opened, the system pauses the recording of the consumable identification label to prevent misrecording or missing recording due to the movement or interference of consumables during the operation. When the cabinet door is closed, the system starts again, begins to identify the consumable label and proceeds to the next step of processing.

[0070] When the system detects that the consumable cabinet door is closed, it will read the identification label of the consumable and perform a matching calculation with the standard label in the standard database to ensure that the identification information of the consumable meets the preset standard. After the label matching is completed, the system further compares the consumable identification label with the historical label in the traceability database to verify whether the storage information, batch, and related operation history of the consumable are consistent. This step is an important link to ensure the accuracy of consumable information.

[0071] After the label comparison and traceability verification are completed, the system will calculate the consumable change amount in this access operation through the analysis of the weight and volume changes of the consumable. The system accurately judges whether the consumable is taken out or stored by reading the difference between the current data and the historical data, and calculates the changed quantity.

[0072] After the calculation of the change amount is completed, the system does not record immediately, but evaluates the data through credibility calculation. The credibility calculation comprehensively evaluates based on the system's historical data, currently observed data, and existing abnormal situations to determine whether the change amount data meets the expectations. If the credibility is higher than the threshold set by the system, then this change amount will be officially recorded.

[0073] In summary, the present invention provides a control method for a medical supply cabinet, including: obtaining the supply weight information, supply volume information, supply identification label, and the state of the supply cabinet door of the supply cabinet; judging the opening and closing state of the supply cabinet door according to the state of the supply cabinet door; when it is determined that the supply cabinet door is closed, matching and calculating the supply identification label with the standard label in the preset standard library to obtain a label matching degree; when the label matching degree is greater than or equal to the preset matching degree threshold, judging the consistency between the supply identification label and the traceability label in the traceability database; when the supply identification label is consistent with the traceability label, calculating the supply change amount according to the supply weight information and the supply volume information to obtain the supply change amount; performing credibility calculation on the supply change amount to obtain a variable credibility, and when the variable credibility is greater than the preset credibility threshold, recording the supply change amount.

[0074] In the present invention, the method can determine whether to record the data of the supply identification label by judging the opening and closing state of the supply cabinet door. When the supply cabinet door is in the open state, the system will temporarily not consider the supply identification label to avoid misrecording or missing recording during the supply change process. This measure ensures that only when the supply cabinet door is closed, the information of the removal or storage of supplies will be accurately recorded, reducing interference factors. Then, by comparing the supply identification label with the standard label and judging the consistency with the traceability label, the supply information and storage information are further confirmed. The method can not only ensure the accuracy of the supply information, but also calculate the credibility of the change amount of each supply, thereby verifying the reliability of the data. Only when the label matching and the change amount credibility meet the preset standards, the storage behavior of the supplies will be recorded. These steps effectively prevent data errors and inconsistencies, providing more reliable supply tracking information for management personnel. In summary, the method can more accurately record the removal and storage behaviors of supplies in the medical supply cabinet by combining the judgment of the warehouse door state, label matching, and traceability mechanism, thereby improving the efficiency and accuracy of medical supply management, reducing the risk of missing recording and misrecording, and ensuring the safety and reliability of supply management.
