[0088] In some embodiments, such as Figure 3 As shown, a storage device control method is provided, comprising the following steps:

[0089] S301, in response to the storage device being in an unlocked state, the location of the storage device is obtained; the storage device is used to store at least one of consumables, samples or reagents.

[0090] In this embodiment of the application, the working state may include, but is not limited to, an unlocked state, a first locked state, a second locked state, an active correction state, a locked state, a first unlocked state, and a second unlocked state.

[0102] In this application embodiment, "reagent" refers to various chemical reagents used in scientific experiments or chemical analysis and other research processes. Optionally, the reagent may include at least one of biochemical reagents, immunological reagents, and microbiological reagents.

[0103] In some embodiments, in response to the storage device being in an unlocked state, obtaining the location of the storage device includes:

[0104] In response to the storage device being in an unlocked state and receiving a locking command for the storage device, the location of the storage device is obtained.

[0105] In some embodiments, the method of obtaining locking commands and active correction commands and unlocking commands in the following embodiments can be that the host computer directly sends commands (locking commands, unlocking commands and / or active correction commands) to the slave computer; or the user presses a physical button on the storage device to send the corresponding signal (unlock signal, locking signal and / or active correction signal) to the slave computer, the slave computer sends the corresponding request (locking request, unlocking request and / or active correction request) to the host computer, and the host computer issues a command to the slave computer after agreeing to the corresponding request.

[0106] S302, when it is determined that the storage device is located at a specified position, the power component in the storage device is controlled to perform the first locking movement according to the first locking parameter; the first locking movement includes: the power component moving in the locking direction for a first number of locking steps.

[0107] In this embodiment, the first locking parameter indicates the motion parameters of the storage device during the first locking motion.

[0108] In this embodiment, the locking direction indicates the direction in which the power member moves clockwise or counterclockwise to close the storage device. For example, the locking direction is the direction in which the blocking push rod pushes the limiting member to move in the direction of closing the storage device.

[0109] In some embodiments, during all locking operations of the storage device, the first locking step number and the second locking step number in the following embodiments can be preset based on empirical values.

[0110] In some embodiments, during the first locking operation of the storage device, the first number of locking steps and the second number of locking steps in subsequent embodiments can be preset based on empirical values. During the second and subsequent locking operations of the storage device, the first number of locking steps can be determined based on the distance when the blocking push rod moves to just contact the limiting member; the second number of locking steps can be determined based on the distance between the current position of the power member and the position of the power member during the first locking operation or when the second locking movement was completed in the previous locking operation.

[0111] S303, during the first locking motion, obtain the first step loss situation of the power component.

[0112] In this embodiment, the first step loss condition indicates the number of steps lost by the power member during the first locking motion. The number of steps lost may include consecutive steps lost and non-consecutive steps lost.

[0113] In this embodiment, continuous step loss indicates the phenomenon that the power component continuously loses step within adjacent time intervals.

[0114] In this embodiment, discontinuous step loss indicates the phenomenon of a time interval between the previous step loss and the next step loss.

[0115] In this embodiment, the step loss indicator power component experiences a phenomenon where, during operation, the actual rotational speed differs from the theoretical rotational speed due to some reason, thus preventing it from performing precise movement according to the preset number of steps or rotational speed. Optionally, step loss includes missed steps and missed steps; in the missed step indicator power component, the number of steps the rotor advances is less than the number of pulses; in the missed step indicator power component, the number of steps the rotor advances is greater than the number of pulses.

[0116] In one embodiment, the number of lost steps is determined based on the difference between the number of pulses and the number of forward steps of the rotor in the power unit.

[0117] In one embodiment, the number of steps lost is determined based on the difference between the preset rotation angle and the actual rotation angle of the power component.

[0118] S304, when the first locking target is met in the first step loss situation, the power component in the storage device is controlled to perform a second locking movement according to the second locking parameter; the second locking movement includes: the power component moves in the locking direction for a second number of locking steps; the locking capacity corresponding to the second locking parameter is greater than the locking capacity corresponding to the first locking parameter.

[0119] In this embodiment of the application, the first locking target indicates the completion conditions of the first locking movement (i.e., the initial locking) of the power member.

[0120] In some embodiments, the first locking target is that the power member generates continuous step loss during the first locking movement, and the number of consecutive step loss steps is greater than or equal to a preset second number of steps.

[0121] For example, the second step can be 2, 3, or 4 steps, etc.

[0122] In this embodiment, the power component may experience jamming and loss of step during operation due to factors such as excessive load, unstable load, and uneven transmission clearance. To reduce misjudgments of step loss caused by these factors, compared to determining that the first locking target is met and completing the initial locking when the power component loses step, this embodiment determines that the first locking target is met by determining that the power component experiences continuous step loss and the number of lost steps is greater than or equal to the second number of steps. This eliminates interference from other factors in judging the step loss situation and reduces the occurrence of misjudgments of step loss.

[0123] In this embodiment, the second locking parameter indicates the motion parameters of the storage device during the second locking motion.

[0124] In this application embodiment, locking capability indicates the ability to keep the storage device locked or secured in any scenario or condition.

[0125] In this embodiment, by implementing two-stage locking during the locking process of the storage device, the situation where the storage device is not fully locked due to the loss of synchronization of the power component during the first locking movement can be improved, ensuring the locking effect and accurately determining the position of the storage device as the locking position. Furthermore, the second locking is only performed after the first locking target is met, i.e., the initial locking is completed; thus, if the first locking target is not met, there is no need for a second locking, saving power consumption and allowing the user to promptly determine if the storage device is in a partially locked state and make timely adjustments.

[0126] In some embodiments, the storage device control method further includes:

[0127] If the first step failure does not meet the first locking target, and the number of movement steps of the power component is equal to the number of first locking steps, then a warning message is output; the warning message is used to indicate locking failure.

[0128] In some embodiments, the output warning information includes at least one of the following:

[0129] Output early warning information on the control interface of the storage device control system, the human-computer interaction device control interface, or the display interface of the sample processing equipment;

[0130] Voice devices based on storage devices control systems or sample processing equipment output warning information.

[0131] The warning information is sent to a third-party platform; the warning information is used for display by the third-party platform.

[0132] In some embodiments, the warning information may include, but is not limited to, at least one of text information, voice information, image information, and color information.

[0133] For example, the output warning information may be displayed as text on the screen of a coagulation analyzer; or it may be displayed as voice signal by an immunoassay analyzer; or it may be generated by the controller of a sample processing device and sent to the user's terminal via SMS, email or other wireless transmission methods.

[0134] In this embodiment, by outputting a warning message when the first locking target is not met in the first out-of-synchronization situation, the warning message can accurately inform the storage device that its current operating state is an unlocked state due to locking failure. On the one hand, the user can take timely countermeasures based on the warning message, such as determining whether the storage device is malfunctioning or re-performing the locking operation; on the other hand, there is no need to perform secondary locking when the first locking target is not met, which can reduce power consumption.

[0135] In some embodiments, the storage device control method further includes:

[0136] During the second locking motion, the second step loss situation of the power component is obtained;

[0137] Based on the second step loss situation, adjust the second locking step number and repeat the second locking movement until the second step loss situation meets the second locking target.

[0138] In this embodiment, the second step loss condition indicates the number of steps lost by the power member during the second locking motion.

[0139] In this embodiment of the application, the second locking target indicates the completion conditions of the second locking movement (i.e., secondary locking) of the power component.

[0140] In some embodiments, the second locking target may be that the number of first steps lost during the second locking motion of the power component is less than the number of first steps; wherein the number of first steps is less than the number of second steps.

[0141] In the embodiments of this application, the first number of lost steps and the second and third number of lost steps in the following embodiments all indicate the total number of lost steps generated by the power component during the movement. The first number of lost steps, the second number of lost steps, and the third number of lost steps all include consecutive lost steps and non-consecutive lost steps.

[0142] For example, the number of steps can be 1.

[0143] In one embodiment, the sample processing device increases or decreases the number of second locking steps and repeats the second locking motion based on the second out-of-step condition until the second out-of-step condition meets the second locking target.

[0144] In this embodiment, the number of second locking steps is adjusted according to the step loss situation during the second locking movement until the second step loss situation meets the second locking target, and the second locking is completed; the locking effect is guaranteed, thereby accurately determining the position of the storage device when it completes the second locking movement as the locking position.

[0145] In some embodiments, based on the second step loss condition, the second locking step number is adjusted, and the second locking motion is repeated until the second step loss condition meets the second locking target, including:

[0146] If it is determined that the second step loss is due to the first step loss being greater than or equal to the preset first step number, then the second locking step number is adjusted; wherein, the second locking step number before adjustment is greater than the second locking step number after adjustment;

[0147] Repeat the second locking motion and adjust the number of the second locking steps until the number of the first missing steps is less than the number of the first step, and determine that the second missing step situation meets the second locking target.

[0148] In some embodiments, the second locking step number is N, and the first step number is 1; if the sample processing device determines that the first missing step number m≥1, the second locking step number is adjusted to N-1, and the power component is controlled to repeat the second locking motion; if the sample processing device determines for the second time that the first missing step number m≥1, the second locking step number is adjusted to N-2, and the power component is controlled to repeat the second locking motion; and so on, until the first missing step number m<1, it is determined that the second locking target is met and the second locking motion is completed; where N is a positive integer and N is greater than 1, and m is greater than or equal to 0.

[0149] In traditional power component movements, various factors can interfere with the locking of the storage device, making it difficult to fully lock. For example, when the power component drives the blocking push rod to rotate, the blocking push rod may be blocked by the limiting component, and a rebound phenomenon may occur due to the collision, resulting in the storage device remaining in an incompletely locked state after completing the locking movement.

[0150] In contrast, in this embodiment, if the first number of missed steps is greater than or equal to a preset number of first steps, the second number of locking steps is reduced and the second locking motion is repeated. This gradually reduces the number of second locking steps, decreasing the number of missed steps during the second locking motion. This ensures that the storage device reaches the locking position just as the power component completes the second number of locking steps, reducing the occurrence of springback due to over-locking by the power component and guaranteeing the locking effect of the storage device.

[0151] In some embodiments, the first locking parameter includes a first current and / or a first speed; the second locking parameter includes a second current and / or a second speed; wherein the first current is less than the second current; and the first speed is greater than the second speed.

[0152] In this embodiment of the application, the first locking parameter may further include a first torque and / or a first frequency; the second locking parameter may further include a second torque and / or a second frequency; wherein, the first torque is less than the second torque; and the first frequency is greater than the second frequency.

[0153] In some embodiments, during the first locking movement, the operating current of the power component is a first current and the operating speed is a first speed; at this time, the torque of the power component is relatively small, the locking capacity is relatively small, and the power component can move to the target position at a relatively fast speed but with a relatively small locking force, such as the position where the blocking push rod contacts the limiting component, to complete the first locking movement.

[0154] In some embodiments, during the second locking motion, the operating current of the power component is the second current and the operating speed is the second speed; at this time, the torque of the power component is relatively large, the locking capacity is relatively large, and the power component can drive the blocking push rod to push the limiting component or the lock axis to move in the locking direction with a relatively large locking force but a relatively slow speed to complete the second locking motion.

[0155] In this embodiment, by setting the second current during the second locking movement to be greater than the first current during the first locking movement, and / or setting the second speed during the second locking movement to be less than the first speed during the first locking movement, on the one hand, the target position, such as the contact position between the limiting member and the blocking push rod, can be reached at a faster speed during the first locking movement, thus improving locking efficiency; on the other hand, a greater locking force can be applied during the second locking movement, further ensuring the locking effect.

[0156] In some embodiments, the storage device control method further includes:

[0157] If the second locking target is met under the second out-of-step condition, the position of the storage device is determined as the locking position and the position of the power component is determined as the target origin position.

[0158] In this embodiment, the locking position indicates the position of the storage device in the fully locked state.

[0159] In this embodiment, the target origin position indicates the position of the power component when it completes the second locking motion.

[0160] In this embodiment, the target origin position is determined by the position of the power component after completing the second locking motion. This eliminates the need for a detection optocoupler for the target origin position, simplifying the mechanical structure, saving costs, and improving the intelligence of the equipment.

[0161] In some embodiments, the storage device control method further includes:

[0162] In response to the storage device being in a locked state, the position detection status of the storage device and the displacement status of the power components are obtained to determine whether the conditions for performing active correction motion are met.

[0163] When the conditions for performing active corrective motion are met, the control power component performs active corrective motion; the active corrective motion includes: the power component moving in the locking direction for a third locking step;

[0164] During the active correction motion, the third step loss situation of the power component is obtained;

[0165] Based on the third step loss situation, adjust the third locking step number corresponding to the active correction movement, and repeat the active correction movement until the third step loss situation meets the active correction target.

[0166] In some embodiments, in response to the storage device being in a locked state, the position detection status of the storage device and the displacement status of the power component are acquired to determine whether the conditions for performing active corrective motion are met, including:

[0167] In response to the storage device being in a locked state and receiving an active correction command for the storage device, the system acquires the position detection status of the storage device and the displacement status of the power components to determine whether the conditions for executing the active correction motion are met.

[0168] In some embodiments, the position of the locked storage device may shift due to other factors, such as equipment failure or user misoperation of the locked storage device (e.g., forced unlocking). If the storage device is in a locked state at this time, the conditions for performing active correction movement can be determined based on the position detection of the storage device and the displacement of the power component, and then the active correction movement can be performed.

[0169] In some embodiments, the third locking step number can be determined based on the distance between the current position of the power component and the target origin position.

[0170] In this embodiment, the third step loss condition indicates the number of second step loss steps generated by the power component during the execution of active correction motion.

[0171] In this embodiment of the application, the conditions for the completion of the active correction motion of the active correction target indicator power member are specified.

[0172] In some embodiments, the active correction target can be that the second number of steps lost during the active correction operation of the power component is less than the third number of steps; wherein, the third number of steps is less than the second number of steps; the third number of steps may be the same as or different from the first number of steps.

[0173] For example, the third step can be 1.

[0174] In this embodiment, by adjusting the third locking step number so that the third step loss situation meets the active correction target, the power component moves to the target origin position, which can further reduce the occurrence of the storage device not being in the locking position and ensure the locking effect of the storage device; it also facilitates accurate positioning when retrieving consumables, samples or reagents from the storage device in the future.

[0175] In some embodiments, the trigger is connected to the body of the storage device; acquiring the position detection status of the storage device and the displacement status of the power component, and determining whether the conditions for performing active correction motion are met, includes:

[0176] Based on the position detection of the trigger and the displacement of the power component, determine whether the conditions for executing active correction motion are met;

[0177] If the trigger is located at the specified position and the position of the power component changes relative to its position when the second locking motion is completed, then the conditions for performing the active correction motion are met.

[0178] For example, such as Figure 2 As shown, the trigger 60 is located below the storage device and is connected to the mounting plate 23 of the storage device. The sample processing equipment can determine the position of the storage device by detecting the position of the trigger 60.

[0179] In this embodiment, by ensuring the trigger element is in a designated position, it is guaranteed that the power component can perform a corresponding locking operation on the storage device during movement, thereby reducing invalid movement of the power component due to the trigger element not being in the designated position. By determining that the position of the power component has changed relative to its position after the second locking movement, it can be determined that the position of the storage device is inconsistent with the target origin position, requiring active correction. Thus, through dual detection of the trigger element and power component positions, it is possible to accurately determine whether the conditions for active correction movement are met, reducing unnecessary resource waste.

[0180] In some embodiments, if the trigger is located at a specified position and the position of the power element changes relative to its position when the second locking motion is completed, then it is determined that the conditions for performing an active corrective motion are met, including:

[0181] If the position change of the power component is within a preset range, then the conditions for performing active correction motion are met; wherein, the position change is determined based on the first sensor; the first sensor is used to determine the position of the power component;

[0182] If the position change of the power component is not within the preset range but the trigger component is within the detection range of the second sensor, then the condition for performing active correction motion is met; wherein, the second sensor is used to determine the position of the trigger component.

[0183] In some embodiments, such as Figure 2 As shown, since the trigger 60 has a certain width, when the trigger 60 is within the detection range of the second sensor 52, it can represent the following two situations: First, the storage device is in a fully locked state; Second, the storage device is inside the sample processing device but is not in a fully locked state.

[0184] In some embodiments, due to factors such as installation errors of the second sensor, it is difficult to accurately determine the entire range within which the trigger is detected by the second sensor. Therefore, the judgment process can be divided into two stages. In the first stage, by setting a preset range, it can be ensured that the trigger can definitely be detected by the second sensor. The second stage determines the judgment result based on the detection result of the second sensor.

[0185] In this embodiment, the preset range can be determined based on empirical values. Alternatively, the preset range can be determined based on the maximum value of the movement of the power member recorded by the first sensor when the trigger is at the farthest distance detectable by the second sensor. Optionally, the preset range is smaller than the maximum value.

[0186] For example, the first sensor can be an encoder, which is used to record the number of movement steps of the power component. When the trigger is located at the farthest distance that the second sensor can detect, the maximum value of the movement of the power component recorded by the first sensor is 105, and the preset range can be 0 to 100.

[0187] In this embodiment, by determining whether the position change of the power component is within a preset range, it is possible to simultaneously determine whether the position of the trigger component is located at a specified position and whether the position of the power component is consistent with the target origin position, thus simplifying the judgment process. If the position change of the power component is not within the preset range, it can be determined that the position of the power component is inconsistent with the target origin position, but since the preset range is smaller than the maximum value, it is impossible to determine whether the trigger component is located at the specified position. Therefore, by determining whether the trigger component is within the detection range of the second sensing element, it is possible to accurately determine whether the trigger component is located at the specified position. Furthermore, through the dual detection of the positions of the trigger component and the power component, the accuracy of whether to trigger active correction can be ensured.

[0188] In some embodiments, based on the third step loss condition, the number of third locking steps corresponding to the active correction movement is adjusted, and the active correction movement is repeated until the third step loss condition meets the active correction objective, including:

[0189] During the active correction motion, if it is determined that the third step loss condition is that the second step loss of the power component is greater than or equal to the preset third step number, then the third locking step number is adjusted; wherein, the third locking step number before adjustment is greater than the third locking step number after adjustment.

[0190] Repeat the active correction movement and the control process of adjusting the third locking step number until the second step loss number is less than the third step number, and determine that the third step loss situation meets the active correction target.

[0191] In some embodiments, the third locking step number is N, and the third step number is 1; if the sample processing device determines that the second missing step number k≥1, the third locking step number is adjusted to N-1, and the power component is controlled to repeatedly perform the active correction movement; if the sample processing device determines for the second time that the second missing step number k≥1, the third locking step number is adjusted to N-2, and the power component is controlled to repeatedly perform the active correction movement; and so on, until the second missing step number k<1, it is determined that the active correction target is met and the active correction movement is completed; where N is a positive integer and N is greater than 1, and k is greater than or equal to 0.

[0192] In this embodiment, if the second number of lost steps is greater than or equal to a preset third number of steps, the third locking step number is reduced and the active correction movement is repeated. In this way, the third locking step number can be gradually reduced so that the storage device reaches the locked position after the power component completes the third locking step, further reducing the occurrence of springback and further ensuring the locking effect of the storage device.

[0193] In some embodiments, the storage device control method further includes:

[0194] In response to the storage device being in a locked state and receiving an unlock command for the storage device, the location of the storage device is obtained;

[0195] When the location of the storage device is determined to be in the designated position, the control power component is used to perform an unlocking motion; the unlocking motion includes: the power component moving in the unlocking direction for a preset number of unlocking steps;

[0196] During the unlocking process, the fourth step failure situation of the power component is obtained;

[0197] Based on the fourth step failure of the power component, the unlocking execution status is determined.

[0198] In some embodiments, determining that the storage device is located at a specified location includes:

[0199] If the trigger is within the detection range of the second sensor, the location of the storage device is determined to be at the specified position.

[0200] In this embodiment, the unlocking motion may include a first unlocking motion and a second unlocking motion; the preset unlocking step count may include a first unlocking step count and a second unlocking step count. Optionally, the first unlocking motion includes: the power member moving in the unlocking direction for a first unlocking step count according to a first unlocking parameter; optionally, the second unlocking motion includes: the power member moving in the unlocking direction for a second unlocking step count according to a second unlocking parameter.

[0201] In this embodiment of the application, the first unlocking parameter includes a third current, a third speed, a third torque and / or a third frequency; the second unlocking parameter includes a fourth current, a fourth speed, a fourth torque and / or a fourth frequency; wherein, the third current is less than the fourth current; the third speed is greater than the fourth speed; the third torque is less than the fourth torque; and the third frequency is greater than the fourth frequency.

[0202] In this embodiment, the unlocking direction indicates that the power member moves in the opposite direction to the locking direction. For example, it is the direction in which the blocking push rod pushes the limiting member to move in the direction of opening the storage device.

[0203] In this embodiment, the fourth step loss condition indicates the third step loss that occurs during the unlocking process of the power component.

[0204] In this embodiment, the unlock execution state indicates the working state of the storage device during the unlocking process. The unlock execution state may include, but is not limited to, a first unlock state, a second unlock state, an unlocked state, and a locked state.

[0205] In this embodiment, the unlocking execution state can be accurately determined by the fourth step failure during the unlocking movement, and corresponding operations can be performed in a timely manner based on the unlocking execution state to ensure the unlocking effect. Furthermore, the unlocking movement can be divided into a first unlocking movement and a second unlocking movement. During the first unlocking movement, the device can move to the target position at a relatively fast unlocking speed, such as the position where the blocking push rod contacts the limiting member; while during the second unlocking movement, the subsequent unlocking operation can be completed with a larger unlocking force.

[0206] In some embodiments, determining the unlocking execution state based on the fourth step failure condition of the power component includes:

[0207] If the fourth step loss is determined to be due to the third step loss being greater than the preset fourth step number, then the unlocking execution status is determined to be an unlocking abnormal status, and the unlocking movement is stopped.

[0208] In some embodiments, the fourth step number can be 0. If the storage device determines that the third step loss of the power component is 1, and the third step loss is greater than the fourth step, it determines that the unlocking execution state is an unlocking abnormal state, stops the unlocking movement, and outputs a warning message; the warning message indicates that the unlocking has failed.

[0209] In this embodiment, when the third number of lost steps exceeds the fourth number of lost steps, the unlocking process is determined to have failed and the unlocking motion is stopped. This allows for timely stopping of the unlocking motion without needing to complete the preset number of unlocking steps, thus saving power. Furthermore, it facilitates timely operation of the storage device by the user after an unlocking failure, such as searching for the cause of the failure or attempting a second unlocking operation.

[0210] In some embodiments, determining the unlocking execution state based on the fourth step failure condition of the power component includes:

[0211] If the fourth step loss is determined to be due to the third step loss being less than or equal to the preset fourth step number, then the unlocking execution status is determined to be the unlocking completed status.

[0212] In this embodiment, the unlocking execution state is set to "unlocking complete" when the preset number of unlocking steps has been completed without any missed steps during the unlocking process. This ensures that no missed steps occur during the unlocking process, guaranteeing the unlocking effect.

[0265] In an alternative embodiment, the motor stops moving and it is determined that the storage device has completed active correction.

[0266] The aforementioned storage device control method, system, and sample processing equipment, by implementing two-stage locking during the locking process of the storage device, can effectively improve the situation of step loss in the storage device; it can improve the situation where the storage device is not fully locked due to step loss of the power component during the first locking movement; it ensures the locking effect and can accurately determine the current position of the storage device as the locking position. Furthermore, the second locking is only performed after the first locking target is met, i.e., the initial locking is completed; thus, if the first locking target is not met, there is no need for a second locking, saving power consumption and allowing users to promptly determine if the storage device is in an incompletely locked state and make timely adjustments.

[0267] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

The solution provided by this system is similar to the implementation described in the above method; therefore, the specific limitations in one or more storage device control system embodiments provided below can be found in the limitations of the storage device control method described above, and will not be repeated here.

[0269] In some embodiments, such as Figure 7 As shown, a storage device control system is provided. The system includes:
