If there is a description of "first", "second", etc., it is only for the purpose of distinguishing technical features and should not be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence of the indicated technical features.

[0036] In the description of the present invention, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0037] Please refer to Figure 1, this embodiment discloses a reagent remaining amount management system, including a display module 110, a remaining amount detection module 120, and a control module 130. The control module 130 is respectively connected to the display module 110 and the remaining amount detection module 120.

[0038] Among them, the display module 110 can adopt a touch display screen, a non-touch display screen such as a liquid crystal display screen or an LED display screen, etc. The display module 110 can be integrated with the control module 130, or the control module 130 is configured with corresponding interfaces for connecting the display module 110.

[0039] The remaining amount detection module 120 can adopt a module based on electronic weighing detection technology, a module based on bubble detection technology, a module based on float detection technology, a module based on soft buckle amount detection technology, etc.

[0040] The control module 130 includes a memory and a processor. The memory is used to store various data and executable programs generated during the relevant reagent remaining amount management process, such as storing the system program of the reagent remaining amount management system, various application programs, or algorithms for implementing various specific functions. It can include one or more computer program products, and the computer program products can include various forms of computer-readable storage media, such as volatile memory and / or non-volatile memory. Volatile memory can include, for example, random access memory (RAM) and / or cache memory, etc. Non-volatile memory can include, for example, read-only memory (ROM), hard disk, flash memory, etc. In the quality control management system, if there is data that needs to be locally stored, it can be stored in the memory.

[0041] The processor can be a central processing unit (CPU), an image processing unit (GPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other forms of processing units with data processing capabilities and / or instruction execution capabilities, and can control other components in the reagent remaining amount management system to perform the desired functions. For example, the processor can include one or more embedded processors, processor cores, microprocessors, logic circuits, hardware finite state machines (FSM), digital signal processors (DSP), image processing units (GPU), or combinations thereof.

[0042] Specifically, the display module 110 is used to display the first remaining amount data of the target reagent. The first remaining amount data is used to characterize the remaining amount data of the target reagent at the previous moment. For example, in the initial state, the data of the remaining amount of the target reagent at the previous moment is configured as a default value. In this embodiment, the first remaining amount data is represented by a relative value. For example, the default value of the first remaining amount data is 100%, or when the first remaining amount data is a null value, the first remaining amount data is default displayed as a state critical value (as described below), such as the state critical value (20%) between the first remaining amount state and the second remaining amount state. Among them, the previous moment is adapted to the current moment, and the value at the previous moment refers to the real-time remaining amount detection of the target reagent by the remaining amount detection module 120 before the current moment during use and the display of the detected remaining amount data through the display module 110.

[0043] The remaining amount detection module 120 is used to perform real-time remaining amount detection on the target reagent to obtain the second remaining amount data at the current moment. In some application examples, a timer is configured to control the remaining amount detection module 120 to perform remaining amount detection on the target reagent according to a preset time period; in other application examples, in response to a change in the remaining amount of the target reagent, remaining amount detection is performed on the target reagent. For example, a sensor is used to detect whether the remaining amount of the target reagent has changed, and when the remaining amount changes, the remaining amount value is calculated. Among them, the remaining amount detection in this embodiment can be based on electronic weighing technology, bubble detection technology, float detection technology, soft buckle amount detection technology, etc. The relevant detection technologies have been fully disclosed in the prior art and will not be elaborated in this embodiment.

[0044] The control module 130 is used to determine the remaining amount difference according to the first remaining amount data and the second remaining amount data, and determine the validity of the second remaining amount data according to the remaining amount difference and a preset fluctuation redundancy;

[0045] When the validity of the second remaining amount data is characterized as valid, the control module 130 is used to update the first remaining amount data displayed by the display module 110 according to the second remaining amount data.

[0046] In the related art, the remaining amount of the reagent is easily interfered by environmental factors. For example, for electronic weighing detection, since the weighing weight is easily affected by the environment, such as vibration, etc., the detected weight fluctuates up and down. This fluctuation has two effects: one is that the weight displayed on the instrument interface also fluctuates up and down, which does not conform to the general habits of humans. For example, when the amount of reagent in the reagent bottle has not changed, the displayed weight should remain unchanged; the other is that when the remaining amount of the reagent is within the alarm critical range of the remaining amount of the reagent, it will cause frequent alarm triggering, seriously affecting the user experience. For example, the remaining amount of the reagent is sometimes less than the alarm threshold and sometimes greater than the alarm threshold, causing discomfort to the user. The same problem also exists in the float detection technology.

[0047] To solve the above problems, in this embodiment, when the remaining amount of the target reagent changes, the current change in the remaining amount is determined to be real and effective based on the remaining amount difference generated by the change and the preset fluctuation redundancy. If it is effective, the first remaining amount data is updated and the updated first remaining amount data is displayed, reducing frequent fluctuations and false alarms caused by environmental factors and facilitating improving the accuracy of reagent remaining amount management.

[0048] In addition, when the validity of the second remaining amount data is characterized as invalid, the control module 130 is used to keep the first remaining amount data displayed by the display module 110.

[0049] Exemplarily, when the detected value of the reagent remaining amount changes due to environmental factor vibration, that is, the remaining amount difference is not zero, the validity of the second remaining amount data is determined based on the remaining amount difference and the preset fluctuation redundancy. When the validity is characterized as invalid, the originally displayed first remaining amount data is kept to avoid frequent changes in the first remaining amount data caused by environmental factors.

[0050] In some application scenarios, the fluctuation redundancy includes an upper fluctuation redundancy range. Determining the validity of the second remaining amount data based on the remaining amount difference and the preset fluctuation redundancy includes:

[0051] When the remaining amount difference does not fall within the upper fluctuation redundancy range, it is determined that the validity of the second remaining amount data is valid.

[0052] For example, please refer to Figure 2 , assuming that the value of the first remaining amount data is V1 and the value of the second remaining amount data is V2, then the remaining amount difference Vx = V1 - V2. Let the interval of the upper fluctuation redundancy range be [-2.3%, 0%). If Vx > 0%, it indicates that the remaining amount of the target reagent has decreased. At this time, it is determined that the current change in the remaining amount is real and effective, that is, the validity of the second remaining amount data is determined to be valid. If Vx < -2.3%, that is, V1 - V2 < -2.3% or V2 - V1 > 2.3%, it indicates that the reagent remaining amount has actually increased. It may be that the user manually adds the reagent to increase the reagent remaining amount, or the instrument automatically adds the reagent, or the reagent container is tilted (in the case of float measurement) to increase the available amount of the target reagent. Similarly, it is determined that the current change in the remaining amount is real and effective, that is, the validity of the second remaining amount data is determined to be valid. If Vx is within the range of [-2.3%, 0%), it indicates that the change in the reagent remaining amount may be caused by environmental factors. At this time, it can be determined that the second remaining amount data is invalid, and the first remaining amount data displayed by the display module 110 is kept. It should be noted that when the remaining amount difference is zero, it indicates that the reagent remaining amount has not changed, and no response may be made or the first remaining amount data displayed by the display module 110 is kept.

[0053] Similarly, in some other application scenarios, the fluctuation redundancy includes a lower fluctuation redundancy range. Determining the validity of the second margin data according to the margin difference and the preset fluctuation redundancy includes:

[0054] When the margin difference does not fall within the lower fluctuation redundancy range, determine that the validity of the second margin data is valid.

[0055] For example, please refer to Figure 3 , assume that the interval of the lower fluctuation redundancy range is (0%, 2.3%]. If Vx > 0%, it indicates that the margin of the target reagent dosage has decreased. However, if the margin difference falls within the range of [0%, 2.3%], it may be due to environmental factor interference. At this time, it is determined that the current margin change is invalid, that is, the validity of the second margin data is determined to be invalid; if Vx > 2.3%, the interference of environmental factors on the margin change can be basically excluded, and it can be determined that the current margin change is truly valid, that is, the validity of the second margin data is determined to be valid; when Vx < 0%, that is, V2 > V1, it indicates that the margin of the target reagent has increased. In the current application scenario, it is also determined that the current margin change is truly valid, that is, the validity of the second margin data is determined to be valid.

[0056] In still some other application scenarios, the fluctuation redundancy includes an upper fluctuation redundancy range and a lower fluctuation redundancy range. Determining the validity of the second margin data according to the margin difference and the preset fluctuation redundancy includes:

[0057] When the margin difference does not fall within the upper fluctuation redundancy range and does not fall within the lower fluctuation redundancy range, determine that the validity of the second margin data is valid.

[0058] For example, please refer to Figure 4 , assume that the interval of the upper fluctuation redundancy range is [-2.3%, 0%), and the interval of the lower fluctuation redundancy range is (0%, 2.3%]. Then, the upper fluctuation redundancy range and the lower fluctuation redundancy range are combined to obtain the interval [-2.3%, 2.3%]. When the margin of the target reagent decreases or increases, if the margin difference does not fall within the upper fluctuation redundancy range and does not fall within the lower fluctuation redundancy range, that is, the margin difference < -2.3% or the margin difference > 2.3%, it is determined that the current margin change is truly valid, that is, the validity of the second margin data is determined to be valid.

[0059] By setting the upper fluctuation redundancy range and the lower fluctuation redundancy range, when the margin difference does not fall into at least one of the upper fluctuation redundancy range and the lower fluctuation redundancy range, the validity of the second margin data can be determined to be valid, and thus the first margin data displayed by the display module 110 can be updated. Different fluctuation redundancy ranges can be set according to actual application requirements, that is, only judge the validity of the margin change during the upper fluctuation, or only judge the validity of the margin change during the lower fluctuation, or judge the validity of the margin change during both the upper and lower fluctuations, which can meet the setting requirements of different application scenarios, reduce frequent fluctuations and false alarms caused by environmental factors, and improve the accuracy of reagent margin management.

[0060] In addition, the control module 130 is further configured to determine the current margin state of the target reagent according to the second margin data and a preset state critical value. To facilitate intuitively grasping the remaining amount of the target reagent, multiple states are divided by configuring the state critical value, and the display module 110 renders the margin display result into different forms according to the current margin, so as to facilitate the user to understand the remaining amount of the target reagent.

[0061] Exemplarily, please refer to Figure 5 , the current margin state includes a first margin state, a second margin state, and a third margin state. The first margin state is used to represent that the margin of the target reagent is sufficient, the second margin state is used to represent that the margin of the target reagent is insufficient, and the third margin state is used to represent that the target reagent is used up. The state critical values include a first critical value and a second critical value, and the first critical value is greater than the second critical value.

[0062] For example, the first critical value is configured to be 20% (as shown by the indication line L1 in Figure 5 ), and the second critical value is configured to be 0% (as shown by the indication line L2 in Figure 5 ). In the initial state, the first margin value of the target reagent is defaulted to 100%, and the current margin state at this time is the first margin state, that is, the current remaining amount is sufficient. After using for a period of time, the margin of the target reagent continuously decreases. When the margin data of the target reagent is less than 20% and greater than 0%, the current margin state is updated to the second margin state, that is, the current remaining amount is insufficient. As the target reagent is continuously used, when the margin data of the target reagent is less than or equal to 0%, the current margin state is updated to the third margin state, that is, the target reagent has been used up, and an alarm prompt can be issued according to relevant configurations.

[0063] In addition, in some embodiments, the state critical values further include a third critical value and a fourth critical value. The third critical value is greater than the second critical value, and the fourth critical value is greater than the first critical value. For example, the third critical value is configured to be 2.3% (as shown by the indication line L3 in Figure 5 ), and the fourth critical value is configured to be 22.3% (as shown by the indication line L4 in Figure 5as indicated by the indication line L4). When the target reagent is in the third remaining amount state, that is, the target reagent has been used up, the user can manually add the target reagent. When the remaining amount data of the target reagent is greater than the third critical value, the current remaining amount state changes from the third remaining amount state to the second remaining amount state. If the target reagent continues to be added and the remaining amount data of the target reagent is greater than the fourth critical value, the current remaining amount state becomes the first remaining amount state.

[0064] In some implementations, the control module 130 is further configured to perform:

[0065] Obtain the remaining amount state at the previous moment;

[0066] In the case where the remaining amount state at the previous moment is the second remaining amount state, determine the validity of the second remaining amount data according to the remaining amount difference and the preset fluctuation redundancy.

[0067] As described above, the fluctuation redundancy includes at least one of the upper fluctuation redundancy range and the lower fluctuation redundancy range. When the remaining amount state at the previous moment is the second remaining amount state (i.e., the remaining amount of the target reagent is insufficient), the change in the remaining amount of the reagent may cause the remaining amount state to switch between the first remaining amount state and the third remaining amount state, thereby triggering an alarm message. To exclude the interference of environmental factors, in some application examples, when the remaining amount difference does not fall within the upper fluctuation redundancy range, it is determined that the validity of the second remaining amount data is valid, otherwise it is invalid. For example, assuming that the interval of the upper fluctuation redundancy range is [-2.3%, 0%), if Vx > 0%, it means that the remaining amount of the target reagent has decreased, or Vx < -2.3%, indicating that the remaining amount of the reagent has increased truly. At this time, it is determined that the current change in the remaining amount is truly valid, that is, the validity of the second remaining amount data is determined to be valid. In other application examples, when the remaining amount difference does not fall within the lower fluctuation redundancy range, it is determined that the validity of the second remaining amount data is valid, otherwise it is invalid. For example, assuming that the interval of the lower fluctuation redundancy range is (0%, 2.3%], if Vx > 0%, it means that the remaining amount of the target reagent has decreased, or Vx > 2.3%, it can be determined that the increase in the remaining amount of the reagent is truly valid, that is, the validity of the second remaining amount data is determined to be valid. In still other application examples, when the remaining amount difference does not fall within the upper fluctuation redundancy range and does not fall within the lower fluctuation redundancy range, it is determined that the validity of the second remaining amount data is valid. For example, assuming that the interval of the upper fluctuation redundancy range is [-2.3%, 0%) and the interval of the lower fluctuation redundancy range is (0%, 2.3%], the upper fluctuation redundancy range and the lower fluctuation redundancy range are combined to obtain the interval [-2.3%, 2.3%]. When the remaining amount of the target reagent decreases or increases, if the remaining amount difference does not fall within the upper fluctuation redundancy range and does not fall within the lower fluctuation redundancy range, that is, the remaining amount difference < -2.3% or the remaining amount difference > 2.3%, it is determined that the current change in the remaining amount is truly valid.

[0068] Compared with the situation where the reagent surplus is sufficient, when the reagent surplus is insufficient, the fluctuation of the reagent liquid level caused by environmental factors is relatively large. The reagent surplus management system provided in this embodiment can, when the surplus state at the current moment is insufficient, determine whether the current surplus change is real and effective according to the surplus difference generated by the change and the preset fluctuation redundancy, which can avoid the problem of frequent fluctuation of the displayed surplus data due to less reagent surplus and improve the stability of reagent surplus detection; optionally, in other surplus state scenarios, such as when the reagent surplus is sufficient, the surplus data can be displayed according to the real-time detected surplus data to meet the display of reagent surplus in different states.

[0069] In some implementation manners, the control module 130 is further configured to update and display the first surplus data according to the second surplus data when the surplus difference is greater than zero, or when the surplus difference is less than zero and does not fall within the preset upper fluctuation redundancy range.

[0070] Generally, during the use of the reagent, in addition to adding the reagent, the upward fluctuation of the surplus is usually caused by environmental factors; while the downward fluctuation of the surplus is more due to the reagent consumption in the normal detection process than environmental factors. Through the above embodiments, the displayed surplus data can be updated in real time when the detected reagent surplus decreases, and the validity of the surplus data can be judged first when the reagent surplus increases, and the displayed surplus data can be updated when it is determined to be valid, and the displayed surplus data can be maintained when it is determined to be invalid; it can be more in line with the reagent use scenario and improve the accuracy of reagent surplus detection.

[0071] In some embodiments, when the surplus state at the previous moment is the second surplus state, determining the validity of the second surplus data according to the surplus difference and the preset fluctuation redundancy includes:

[0072] When the surplus state at the previous moment is the second surplus state, if the second surplus data is greater than the state critical value corresponding to the third surplus state and the surplus difference does not fall within the lower fluctuation redundancy range, then determine that the validity of the second surplus data is valid;

[0073] If the second surplus data is greater than the state critical value corresponding to the third surplus state and the surplus difference falls within the lower fluctuation redundancy range, then determine that the validity of the second surplus data is invalid;

[0074] Exemplarily, as exemplified above, the state critical value corresponding to the third margin state is the second critical value, i.e., 0%, and the interval of the downward fluctuation redundancy range is (0%, 2.3%]. Suppose the first margin data V1 is 4% and the second margin data V2 is 2%, and the margin difference Vx = V1 - V2 = 2%. Since the margin difference falls within the downward fluctuation redundancy range, the validity of the second margin data is determined to be invalid at this time. However, if the second margin data V2 is 1%, then the margin difference Vx = V1 - V2 = 3%, which does not fall within the downward fluctuation redundancy range, and thus the validity of the second margin data is determined to be valid.

[0075] In some application examples, the control module 130 is further configured to:

[0076] In the case where the second margin data is less than or equal to the state critical value corresponding to the third margin state, update and display the first margin data according to the state critical value corresponding to the third margin state, and update the current margin state to the third margin state.

[0077] Exemplarily, as exemplified above, the state critical value corresponding to the third margin state is the second critical value, i.e., 0%. Suppose the first margin data V1 is 3% and the current margin state is the second margin state, that is, the remaining amount of the target reagent is insufficient. When the second margin data V2 is 0%, that is, the numerical value of the second margin data is equal to the second critical value, the first margin data is updated and displayed as the second critical value (i.e., 0%), and the current margin state is updated from the second margin state to the third margin state, that is, the current margin state is updated to the reagent used up. Of course, according to actual application requirements, the second critical value can be configured as a value greater than zero such as 1%, 1.5%, or 2%.

[0078] In some embodiments, in the case where the current margin state at the previous moment is the third margin state, the process for the control module 130 to determine the validity of the second margin data according to the margin difference and the preset fluctuation redundancy includes:

[0079] In the case where the margin difference is greater than zero or does not fall within the preset upward fluctuation redundancy range, determine the validity of the second margin data to be valid;

[0080] In the case where the margin difference is less than zero and falls within the upward fluctuation redundancy range, determine the validity of the second margin data to be invalid.

[0081] As shown in the above example, the third remaining amount state is used to indicate that the target reagent has been used up. At this time, the target reagent can be added automatically or manually to change the remaining amount data of the target reagent. When the current remaining amount state at the previous moment is the third remaining amount state, determine whether the second remaining amount data is true and valid according to the remaining amount difference and the upper fluctuation redundancy range. For example, the range of the upper fluctuation redundancy range is [-2.3%, 0%). Assume that the first remaining amount data V1 is 0% and the second remaining amount data V2 is 2%. Then the remaining amount difference Vx = V1 - V2 = -2%, which falls within the upper fluctuation redundancy range. At this time, it is determined that the validity of the second remaining amount data is invalid; when the second remaining amount data V2 is 3%, the remaining amount difference is Vx = V1 - V2 = -3%. At this time, it is determined that the validity of the second remaining amount data is valid. In some application examples, the state critical value between the second remaining amount state and the third remaining amount state, that is, the second critical value, can be configured as a value greater than zero, such as 2%. At this time, when the first remaining amount data is 1.5% and the second remaining amount data is 1%, the remaining amount difference Vx = V1 - V2 = 0.5%, indicating that the target reagent may be truly consumed. Therefore, it is determined that the validity of the second remaining amount data is valid.

[0082] In some of these application examples, the control module 130 is further configured to:

[0083] When the remaining amount state at the previous moment is the first remaining amount state, update the first remaining amount data displayed by the display module 110 according to the second remaining amount data;

[0084] Exemplarily, in the first remaining amount state, the remaining amount of the target reagent is in a sufficient state, and the change of the reagent remaining amount will not repeatedly trigger an alarm. Therefore, the first remaining amount data can be updated in real time to the second remaining amount data, that is, update the first remaining amount data displayed by the display module 110 according to the second remaining amount data.

[0085] In some of these application examples, the control module 130 is further configured to: when the validity is characterized as invalid, keep displaying the first remaining amount data.

[0086] For example, when the remaining amount difference falls within any one of the upper fluctuation redundancy range or the lower fluctuation redundancy range, it may be caused by environmental factor interference. To avoid inconveniencing the user due to frequent data changes, when the validity is characterized as invalid, keep displaying the first remaining amount data.

[0087] Currently, the commonly used alarm prompt method gives an alarm prompt when the remaining amount reaches a certain fixed value (using relative quantity, such as 20% of the total capacity; or using absolute quantity, such as remaining 1L). This method has the following defects: Since the usage scenarios vary greatly, some users have a large daily sample volume, while some users have a small daily sample volume. If a fixed set value is used for alarm, for users with a large daily sample volume, the remaining amount after early warning can continue to meet the test for about 0.5 days; however, for users with a small daily sample volume, the remaining amount after early warning can continue to meet the test for about 1 week. For such users, obviously the timing of early warning is inappropriate, seriously affecting the user experience. Whether the fixed value is set too high or too low, it cannot meet the requirements of different sample volume users for the time they can continue to use after early warning.

[0088] When the effectiveness is characterized as effective, the control module 130 is further configured to:

[0089] When the numerical interval between the first remaining amount data and the second remaining amount data includes the state critical value, update and display the current remaining amount state according to the second remaining amount data;

[0090] As exemplified above, the value of the state critical value (i.e., the first critical value) between the first remaining amount state and the second remaining amount state is 20%. Suppose the first remaining amount data is 21% and the second remaining amount data is 18%, then the numerical interval between the first remaining amount data and the second remaining amount data is [18%, 21%]. This numerical interval includes the first critical value. Since the second remaining amount data is less than the first critical value, the current reagent remaining amount state enters the second remaining amount state from the first remaining amount state, that is, update and display the current remaining amount state according to the second remaining amount data.

[0091] Among them, the state critical value is determined based on the historical usage information of the target reagent or based on the input instruction received by the input module 140 from the user.

[0092] Please refer to Figure 6 , to be compatible with more application scenarios, the reagent remaining amount management system further includes an input module 140. The input module 140 is connected to the control module 130. The input module 140 is configured to determine the state critical value in response to the input instruction of the user. Exemplarily, the remaining amount of the reagent at the time of early warning is designed to be a configurable mode, which can be set by the user according to their own usage habits, or set by the engineer according to the user's needs. Moreover, it can be set according to the user's habit to give an early warning when the remaining amount approximately meets 0.5 days, 1 day or other durations. When the user's daily sample volume changes, the remaining amount at the time of early warning, that is, the state critical value, can be dynamically adjusted to match the current usage scenario.

[0093] In some application examples, the control module 130 is further configured to obtain historical usage information of the target reagent and determine a status critical value based on the historical usage information. For example, based on an AI model, according to the reagent consumption of the target reagent on the previous day or during a previous period of time, dynamically predict the reagent consumption for the next day or a subsequent period of time, so as to automatically adjust the remaining amount when the reagent remaining amount alarms, that is, determine the status critical value.

[0094] The reagent remaining amount alarm of this embodiment is accurate and stable, and will not fluctuate due to external influences; the same set of software control programs can be compatible with the usage scenarios of different users, so that the remaining amount after reagent warning can meet the usage requirements of different users; when the usage scenario of a certain user changes, the remaining amount after reagent warning can be adjusted without the intervention of the equipment manufacturer, so that the duration that the reagent can continue to be used after warning is stable within a reasonable range; through the AI model of the instrument, the reagent consumption is intelligently predicted and the remaining amount after warning is intelligently adjusted, so that the duration that the reagent for any user application scenario can continue to be used after warning is stable within a reasonable range.

[0095] This embodiment also provides a sample analyzer, including the above-mentioned reagent remaining amount management system;

[0096] In addition, the sample analyzer further includes: a reagent loading module for loading the target reagent, and the target reagent is used for at least one of cleaning the sample analyzer and performing a fusion reaction with the sample to be tested. For the sake of avoiding repetition, the content not involved in this sample analyzer embodiment can refer to the above-mentioned reagent remaining amount management system embodiment.

[0097] The reagent remaining amount alarm of this embodiment is accurate and stable, and will not fluctuate due to external influences; the same set of software control programs can be compatible with the usage scenarios of different users, so that the remaining amount after reagent warning can meet the usage requirements of different users; when the usage scenario of a certain user changes, the remaining amount after reagent warning can be adjusted without the intervention of the equipment manufacturer, so that the duration that the reagent can continue to be used after warning is stable within a reasonable range; through the AI model of the instrument, the reagent consumption is intelligently predicted and the remaining amount after warning is intelligently adjusted, so that the duration that the reagent for any user application scenario can continue to be used after warning is stable within a reasonable range.

[0098] Please refer to Figure 7 , this embodiment also provides a reagent remaining amount management method, including steps S110 to S160. It should be noted that the steps of this embodiment are numbered only for the convenience of review and understanding, rather than limiting the execution order of the steps. In actual applications, it can be adaptively adjusted according to the logical relationship between the steps. The content of each step is described in detail below:

[0099] S110. Display the first remaining amount data of the target reagent, where the first remaining amount data is used to characterize the remaining amount data of the target reagent at the previous moment;

[0100] S120. Conduct real-time remaining amount detection on the target reagent to obtain the second remaining amount data at the current moment;

[0101] S130. Determine the remaining amount difference based on the first remaining amount data and the second remaining amount data;

[0102] S140. Determine the validity of the second remaining amount data based on the remaining amount difference and the preset fluctuation redundancy;

[0103] S150. When the validity is characterized as valid, update and display the first remaining amount data according to the second remaining amount data.

[0104] In this embodiment, when the remaining amount of the target reagent changes, the remaining amount difference generated by the change and the preset fluctuation redundancy are used to determine whether the current remaining amount change is real and effective. If it is effective, the first remaining amount data is updated and the updated first remaining amount data is displayed, reducing false alarms caused by environmental factors and facilitating improving the accuracy of reagent remaining amount management. Among them, the previous moment in step S110 is adapted to the current moment, and the value at the previous moment refers to the remaining amount data detected and displayed during the use process of the target reagent before the current moment.

[0105] In some cases where the fluctuation redundancy includes an upper fluctuation redundancy range, step S140. Determine the validity of the second remaining amount data according to the remaining amount difference and the preset fluctuation redundancy, including:

[0106] S141. When the remaining amount difference does not fall within the upper fluctuation redundancy range, determine that the validity of the second remaining amount data is valid.

[0107] For example, assume that the value of the first remaining amount data is V1 and the value of the second remaining amount data is V2, then the remaining amount difference Vx = V1 - V2. Let the interval of the upper fluctuation redundancy range be [-2.3%, 0%). If Vx > 0%, it means that the remaining amount of the target reagent has decreased. At this time, it is determined that the current remaining amount change is real and effective, that is, the validity of the second remaining amount data is determined to be valid; if Vx < -2.3%, that is, V2 - V1 > 2.3%, it means that the remaining amount of the reagent has actually increased. It may be that the user manually adds the reagent to increase the remaining amount of the reagent, or the instrument automatically adds the reagent, or the reagent container is tilted (in the case of float measurement) to increase the available amount of the target reagent. Similarly, it is determined that the current remaining amount change is real and effective, that is, the validity of the second remaining amount data is determined to be valid. If Vx is within the range of [-2.3%, 0%), it means that the change in the remaining amount of the reagent may be caused by environmental factors. At this time, it can be determined that the second remaining amount data is invalid and the first remaining amount data is maintained.

[0108] Similarly, in some other application scenarios, the fluctuation redundancy includes a lower fluctuation redundancy range. Step S140 of determining the validity of the second margin data according to the margin difference and the preset fluctuation redundancy includes:

[0109] Step S141 of determining the validity of the second margin data as valid when the margin difference does not fall within the lower fluctuation redundancy range.

[0110] For example, assume the interval of the lower fluctuation redundancy range is (0%, 2.3%]. If Vx > 0%, it indicates that the margin of the target reagent dosage has decreased. However, if the margin difference falls within the range of (0%, 2.3%], it may be due to environmental factor interference. In this case, it is determined that the current margin change is invalid, that is, the validity of the second margin data is determined to be invalid. If Vx > 2.3%, the interference of environmental factors on the margin change can be basically excluded, and it can be determined that the current margin change is truly valid, that is, the validity of the second margin data is determined to be valid. When Vx < 0%, that is, V2 > V1, it indicates that the margin of the target reagent has increased, and in the current application scenario, it is also determined that the current margin change is truly valid, that is, the validity of the second margin data is determined to be valid.

[0111] In some other application scenarios, the fluctuation redundancy includes an upper fluctuation redundancy range and a lower fluctuation redundancy range. Determining the validity of the second margin data according to the margin difference and the preset fluctuation redundancy includes:

[0112] Determining the validity of the second margin data as valid when the margin difference does not fall within the upper fluctuation redundancy range and does not fall within the lower fluctuation redundancy range.

[0113] For example, assume the interval of the upper fluctuation redundancy range is [-2.3%, 0%), and the interval of the lower fluctuation redundancy range is (0, 2.3%]. Then, the upper fluctuation redundancy range and the lower fluctuation redundancy range are combined to obtain the interval [-2.3%, 2.3%]. When the margin of the target reagent decreases or increases, if the margin difference does not fall within the upper fluctuation redundancy range and does not fall within the lower fluctuation redundancy range, that is, the margin difference < -2.3% or the margin difference ≥ 2.3%, it is determined that the current margin change is truly valid, that is, the validity of the second margin data is determined to be valid.

[0114] In addition, the reagent margin management method of this embodiment further includes:

[0115] S160 of determining the current margin state of the target reagent according to the second margin data and the preset state critical value.

[0116] The current remaining amount status includes a first remaining amount status, a second remaining amount status, and a third remaining amount status. The first remaining amount status is used to indicate that the remaining amount of the target reagent is sufficient, the second remaining amount status is used to indicate that the remaining amount of the target reagent is insufficient, and the third remaining amount status is used to indicate that the target reagent has been used up. The status critical values include a first critical value and a second critical value, where the first critical value is greater than the second critical value. The status critical values also include a third critical value and a fourth critical value, where the third critical value is greater than the second critical value and the fourth critical value is greater than the first critical value.

[0117] The reagent remaining amount management method of this embodiment further includes:

[0118] S171. Obtain the remaining amount status at the previous moment;

[0119] S172. When the remaining amount status at the previous moment is the second remaining amount status, determine the validity of the second remaining amount data according to the remaining amount difference and the preset fluctuation redundancy.

[0120] Exemplarily, the fluctuation redundancy includes at least one of an upper fluctuation redundancy range and a lower fluctuation redundancy range. When the remaining amount status at the previous moment is the second remaining amount status (i.e., the remaining amount of the target reagent is insufficient), the change in the remaining amount of the reagent may cause the remaining amount status to switch between the first remaining amount status and the third remaining amount status, thereby triggering an alarm message. To exclude the interference of environmental factors, the validity of the second remaining amount data is determined according to the remaining amount difference and at least one of the upper fluctuation redundancy range and the lower fluctuation redundancy range, reducing false alarms caused by environmental factors and being beneficial to improving the accuracy of reagent remaining amount management.

[0121] Among them, step S172 includes:

[0122] S1721. When the remaining amount status at the previous moment is the second remaining amount status, if the second remaining amount data is greater than the status critical value corresponding to the third remaining amount status and the remaining amount difference does not fall within the lower fluctuation redundancy range, determine that the validity of the second remaining amount data is valid;

[0123] S1722. If the second remaining amount data is greater than the status critical value corresponding to the third remaining amount status and the remaining amount difference falls within the lower fluctuation redundancy range, determine that the validity of the second remaining amount data is invalid;

[0124] Exemplarily, as exemplified above, the state critical value corresponding to the third margin state is the second critical value, i.e., 0%, and the interval of the downward fluctuation redundancy range is (0%, 2.3%]. Suppose the first margin data V1 is 4% and the second margin data V2 is 2%, and the margin difference Vx = V1 - V2 = 2%. Since the margin difference falls within the downward fluctuation redundancy range, the validity of the second margin data is determined to be invalid at this time. If the second margin data V2 is 1%, then the margin difference Vx = V1 - V2 = 3%, which does not fall within the downward fluctuation redundancy range, and the validity of the second margin data is determined to be valid.

[0125] In some implementations, the reagent margin management method further includes:

[0126] S181. When the second margin data is less than or equal to the state critical value corresponding to the third margin state, update and display the first margin data according to the state critical value corresponding to the third margin state, and update the current margin state to the third margin state.

[0127] Exemplarily, as exemplified above, the state critical value corresponding to the third margin state is the second critical value, i.e., 0%. Suppose the first margin data V1 is 3% and the current margin state is the second margin state, that is, the margin of the target reagent is insufficient. When the second margin data V2 is 0%, that is, the value of the second margin data is equal to the second critical value, update and display the first margin data as the second critical value (i.e., 0%), and update the current margin state from the second margin state to the third margin state, that is, the current margin state is updated to the reagent used up. Of course, according to actual application requirements, the second critical value can be configured as a value greater than zero such as 1%, 1.5%, or 2%.

[0128] In some implementations, when the current margin state at the previous moment is the third margin state, the reagent margin management method further includes:

[0129] S182. When the margin difference is greater than zero or does not fall within the preset upward fluctuation redundancy range, determine that the validity of the second margin data is valid;

[0130] S183. When the margin difference is less than zero and falls within the upward fluctuation redundancy range, determine that the validity of the second margin data is invalid.

[0131] As shown in the above example, the third remaining amount state is used to indicate that the target reagent has been used up. At this time, the target reagent can be added automatically or manually to change the remaining amount data of the target reagent. When the current remaining amount state at the previous moment is the third remaining amount state, determine whether the second remaining amount data is true and valid according to the remaining amount difference and the upper fluctuation redundancy range. For example, the interval of the upper fluctuation redundancy range is [-2.3%, 0%). Suppose the first remaining amount data V1 is 0% and the second remaining amount data V2 is 2%, then the remaining amount difference Vx = V1 - V2 = -2%, which falls within the upper fluctuation redundancy range. At this time, determine that the validity of the second remaining amount data is invalid; when the second remaining amount data V2 is 3%, the remaining amount difference is Vx = V1 - V2 = -3%. At this time, determine that the validity of the second remaining amount data is valid. In some application examples, the state critical value between the second remaining amount state and the third remaining amount state, that is, the second critical value, can be configured as a value greater than zero, such as 2%. At this time, when the first remaining amount data is 1.5% and the second remaining amount data is 1%, the remaining amount difference Vx = V1 - V2 = 0.5%, indicating that the target reagent may be truly consumed. Therefore, determine that the validity of the second remaining amount data is valid.

[0132] The reagent remaining amount management method of this embodiment further includes:

[0133] S184. When the remaining amount state at the previous moment is the first remaining amount state, update and display the first remaining amount data according to the second remaining amount data;

[0134] Exemplarily, in the first remaining amount state, the remaining amount of the target reagent is in a sufficient state, and the change of the reagent remaining amount will not repeatedly trigger an alarm. Therefore, the first remaining amount data can be updated in real time to the second remaining amount data, that is, the first remaining amount data updated and displayed according to the second remaining amount data.

[0135] In some of these application examples, the reagent remaining amount management method further includes:

[0136] S185. When the validity characterization is invalid, keep displaying the first remaining amount data.

[0137] For example, when the remaining amount difference falls within any one of the upper fluctuation redundancy range or the lower fluctuation redundancy range, it may be caused by environmental factor interference. To avoid inconvenience to users due to frequent data changes, when the validity characterization is invalid, keep displaying the first remaining amount data.

[0138] When the validity characterization is valid, the reagent remaining amount management method further includes:

[0139] S186. When the numerical interval between the first remaining amount data and the second remaining amount data contains the state critical value, update and display the current remaining amount state according to the second remaining amount data;

[0140] Among them, the status critical value is determined based on the historical usage information of the target reagent or based on the user's input instruction.

[0141] As shown in the above example, the value of the status critical value (i.e., the first critical value) between the first remaining amount state and the second remaining amount state is 20%. Suppose the first remaining amount data is 21% and the second remaining amount data is 18%. Then the numerical interval between the first remaining amount data and the second remaining amount data is [18%, 21%]. This numerical interval contains the first critical value. Since the second remaining amount data is less than the first critical value, the current reagent remaining amount state enters the second remaining amount state from the first remaining amount state, that is, the current remaining amount state is updated and displayed according to the second remaining amount data.

[0142] The reagent remaining amount alarm in this embodiment is accurate and stable, and will not fluctuate due to external influences; the same set of software control programs can be compatible with the usage scenarios of different users, so that the remaining amount after reagent warning can meet the usage requirements of different users; when the usage scenario of a certain user changes, the remaining amount after reagent warning can be adjusted by itself without the intervention of the equipment manufacturer, so that the duration that the reagent can continue to be used after warning is stable within a reasonable range; through the AI model of the instrument, the reagent consumption is intelligently predicted and the remaining amount after warning is intelligently adjusted, so that the duration that the reagent can continue to be used after warning for any user application scenario is stable within a reasonable range. Among them, in order to avoid repetition, the content not involved in the embodiment of this reagent remaining amount management method can refer to the embodiment of the above reagent remaining amount management system.

[0143] Please refer to Figure 8 In addition, this embodiment also provides a reagent remaining amount management method, including steps S210 to S250. It should be noted that the steps in this embodiment are numbered only for the convenience of review and understanding, rather than limiting the execution order of the steps. In actual applications, it can be adaptively adjusted according to the logical relationship between the steps. The content of each step is described in detail below:

[0144] S210. Display the first remaining amount data of the target reagent, where the first remaining amount data is used to represent the remaining amount data of the target reagent at the previous moment;

[0145] S220. Perform real-time remaining amount detection on the target reagent to obtain the second remaining amount data at the current moment;

[0146] S230. Determine the remaining amount difference according to the first remaining amount data and the second remaining amount data;

[0147] S240. When the remaining amount difference is greater than zero, or the remaining amount difference is less than zero and does not fall into the preset upper fluctuation redundancy range, update and display the first remaining amount data according to the second remaining amount data.

[0148] For example, assume that the value of the first margin data is V1 and the value of the second margin data is V2. Then, the margin difference Vx = V1 - V2. Let the interval of the upper fluctuation redundancy range be [-2.3%, 0%). Among them, the first redundancy threshold is -2.3%. If Vx > 0%, it indicates that the margin of the target reagent has decreased. At this time, it is determined that the current margin change is real and effective. Update the first margin data according to the second margin data and refresh the margin display result of the target reagent, that is, display the updated first margin data. If Vx < 0%, that is, V2 > V1, it indicates that the margin of the target reagent has increased. However, this increase may be caused by the influence of environmental factors on the liquid level. And if Vx < -2.3%, that is, V2 - V1 > 2.3%, it indicates that the user manually adds the reagent to increase the reagent margin, or the instrument automatically adds the reagent, or the reagent container is tilted (in the case of float measurement) to increase the available amount of the target reagent. Similarly, it is determined that the current margin change is real and effective. Update the first margin data according to the second margin data and refresh the margin display of the target reagent. If Vx is within the range of [-2.3%, 0%), it indicates that the change in the reagent margin may be caused by environmental factors. At this time, it can be determined that the second margin data is invalid, and the first margin data displayed by the display module 110 is maintained.

[0149] Generally, during the use of the reagent, except for adding the reagent, the upward fluctuation of the margin is usually caused by environmental factors; while the downward fluctuation of the margin is more due to the consumption of the reagent during the normal detection process than environmental factors. Through the above embodiments, the displayed margin data can be updated in real time when the margin of the detected reagent decreases, and the effectiveness can be judged first when the margin of the reagent increases, and the displayed margin data can be updated when it is determined to be effective, and the displayed margin data can be maintained when it is determined to be invalid; it can be more in line with the reagent usage scenario and improve the accuracy of reagent margin detection.

[0150] In this embodiment, when the margin of the target reagent changes, the current margin change is determined to be real and effective according to the margin difference generated by the change and the preset upper fluctuation redundancy range. If it is effective, the first margin data is updated and the margin display result is refreshed, reducing false alarms caused by environmental factors, which is beneficial to improving the accuracy of reagent margin management. Among them, the previous moment of step S110 is adapted to the current moment, and the value of the previous moment refers to the real-time margin detection of the target reagent and the display of the detected margin data before the current moment during the use process.

[0151] The reagent remaining amount alarm in this embodiment is accurate and stable, and will not fluctuate due to external influences; the same set of software control programs can be compatible with the usage scenarios of different users, so that the remaining amount after reagent early warning can meet the usage requirements of different users; when the usage scenario of a certain user changes, the remaining amount after reagent early warning can be adjusted by the user himself without the intervention of the equipment manufacturer, so that the duration that the reagent can continue to be used after early warning is stable within a reasonable range; through the AI model of the instrument, the reagent consumption is intelligently predicted and the remaining amount after early warning is intelligently adjusted, so that the duration that the reagent for any user application scenario can continue to be used after early warning is stable within a reasonable range. Among them, in order to avoid repetition, the content not involved in the embodiment of this reagent remaining amount management method can refer to the above-mentioned embodiment of the reagent remaining amount management method.
