[0032] FIG2 is a flow chart of a method for adjusting the motor speed according to an embodiment of the present application. As shown in FIG2 , the method includes the following steps:

[0033] Step S202: detecting the initial mixing speed of the motor, wherein the motor is used to drive the mixing machine to mix a variety of materials.

[0034] As an optional embodiment, the motor speed adjustment method provided in the embodiments of the present application can be implemented by a controller or regulator that adjusts the motor speed. The controller or regulator can be a button or switch fixed to the motor, or an adjustable roller, or a controller or regulator that is independent of the motor and not fixed to the motor.

[0035] As an optional embodiment, as shown in FIG5 , the initial mixing speed of the motor can be detected together with an optical coupler sensor and a baffle, and the optical coupler sensor is used to monitor the movement of the baffle. When the baffle passes through the optical coupler sensor, the optical coupler sensor will generate a signal, thereby detecting the initial mixing speed. As shown in FIG6 , a Hall effect sensor can also be used to detect the initial mixing speed of the motor. The Hall effect is used to detect the initial mixing speed. When the magnet on the rotor passes through the Hall sensor, a Hall voltage is generated, thereby detecting the initial mixing speed. In addition to using a sensor method to detect the initial mixing speed of the motor, the initial mixing speed of the motor can also be detected by using a tachometer. The tachometer can determine the initial mixing speed of the motor by measuring the rotation speed of the motor rotor. By detecting the initial mixing speed of the motor with a sensor or a tachometer, the initial mixing speed of the motor can be accurately and real-time known.

[0036] As an optional embodiment, the motor can be a DC motor or a stepper motor. The mixing machine can be a device that can mix other materials, and the multiple materials can be materials of the same type or materials of different types. When the mixing machine is a fully automatic immunoassay analyzer, the multiple materials can be target analytical substances such as antibodies and antigens contained in the blood sample to be tested, and mixing the multiple materials can be mixing the multiple target analytical substances in the sample to be tested, or mixing the multiple target analytical substances in the sample to be tested with other reagents. The above-mentioned mixing machine and multiple materials are just an example, and there are other mixing machines and multiple materials, which are not listed here one by one.

[0037] Step S204: obtaining a preset first speed threshold range.

[0038] As an optional embodiment, the first speed threshold range is used as a basis for determining whether to adjust the initial mixing speed of the motor.

[0039] In step S206, if the initial mixing speed is not within the first speed threshold range, the motor is roughly adjusted until the adjusted mixing speed is within the first speed threshold range, or the number of rough adjustments to the motor is less than or equal to a first predetermined number. A smaller number of rough adjustments results in a larger adjustment range.

[0040] In the above optional embodiment, the stopping condition for coarse adjustment of the motor can be that the adjusted mixing speed is within the first speed threshold range, or the number of times the motor is coarsely adjusted is less than or equal to the first predetermined number, or whether the adjusted mixing speed is within the first speed threshold range together with the number of coarse adjustments can be used as the basis for judging whether the coarse adjustment is completed. When the stopping condition for coarse adjustment of the motor is that the adjusted mixing speed is within the first speed threshold range, the number of coarse adjustments can be unlimited, and the coarse adjustment can be performed an unlimited number of times until the adjusted mixing speed is within the first speed threshold range, at which time the coarse adjustment stops. When the stopping condition for coarse adjustment of the motor is that the number of times the motor is coarsely adjusted is less than or equal to the first predetermined number, if the first predetermined number is 10, that is, the number of times the motor is coarsely adjusted can be any one of 1 to 10 times, then the number of times the motor is coarsely adjusted can be 5 stops, 7 stops, or 10 stops. When the adjusted mixing speed is within the first speed threshold range and the number of rough adjustments are used as a basis for determining whether the rough adjustment is complete, the rough adjustment of the motor can be stopped only when the number of times is within the first predetermined number and the adjusted mixing speed is also within the first speed threshold range. The above is only an example of rough adjustment of the motor. There are many other ways to perform rough adjustment, which are not listed here one by one.

[0041] As an optional embodiment, a variety of coarse adjustment methods can be used to roughly adjust the motor. For example, the following coarse adjustment method can be used: obtaining a target speed for determining a first speed threshold range; obtaining the current mixing speed and current drive parameters of the motor before coarse adjustment; obtaining a first speed deviation between the current mixing speed and the target speed; and coarsely adjusting the motor based on the current drive parameters and the first speed deviation. Compared to not adjusting based on drive parameters and the speed deviation, coarse adjustment based on the drive parameters and the speed deviation will produce a more precise adjustment effect on the motor speed.

[0042] In the above optional embodiment, the minimum value of the above-mentioned first speed threshold range can be the target speed minus the adjustment allowable deviation, and the maximum value of the first speed threshold range can be the target speed plus the adjustment allowable deviation. For example, the target speed is 30r / min, and when the adjustment allowable deviation is 0.5r / min, the minimum value of the first speed threshold range at this time is 29.5r / min, and the minimum value of the first speed threshold range is 30.5r / min, that is, the first speed threshold range is 29.5r / min to 30.5r / min. If the current mixing speed is 40r / min, 40r / min is not within the first speed threshold range (29.5r / min to 30.5r / min). At this time, the motor needs to be roughly adjusted. Subtracting the target speed 30r / min from the current mixing speed 40r / min, the first speed deviation is 10r / min. According to the first speed deviation at this time is 10r / min, the driving parameters of the current driving parameters are adjusted to obtain new driving parameters. The new driving parameters make the current mixing speed of the motor roughly change towards the target speed to obtain a new mixing speed. At this time, the new mixing speed and the new driving parameters will be used as the current mixing speed and current driving parameters for the next adjustment. The motor will continue to be roughly adjusted until the absolute value of the first speed deviation is less than the allowable adjustment deviation, or the number of adjustments is less than or equal to the first predetermined number, and then the rough adjustment of the motor will be stopped.

[0043] As an optional embodiment, the motor is roughly adjusted based on the current driving parameters and the first speed deviation. The following adjustment method can be used to obtain a rough adjustment coefficient; the motor is roughly adjusted based on the current driving parameters, the first speed deviation and the rough adjustment coefficient.

[0044] In the above optional embodiment, when the motor is roughly adjusted based on the current driving parameters, the first speed deviation and the rough adjustment coefficient, a variety of methods can be used. For example, the product of the first speed deviation and the rough adjustment coefficient can be calculated first to obtain a first result (i.e., the driving parameter adjustment amount), and the first result is added to the current driving parameters to obtain a second result, which is used as the new driving parameters of the motor. The new driving parameters make the current mixing speed of the motor roughly change toward the target speed, and a new mixing speed is obtained. Afterwards, based on the new mixing speed and the target speed, a new first speed deviation is determined again, and then the motor is adjusted until it is adjusted to meet the predetermined conditions. Through the above steps, the current driving parameters of the motor can be obtained, the current mixing speed can be obtained based on the current driving parameters, and the new first speed deviation can be obtained again based on the current mixing speed and the target speed, so that it can be known whether the rough adjustment of the motor is completed. Compared with not relying on the rough adjustment coefficient, the speed of the motor can be adjusted more accurately based on the rough adjustment coefficient, the adjustment accuracy is higher, and the speed regulation process is more efficient.

[0045] Step S208: Finely adjust the motor until the adjusted mixing speed is within the second speed threshold range, or the number of fine adjustments to the motor is less than or equal to a second predetermined number, where the first speed threshold range includes the second speed threshold range. Compared to coarse adjustment, fine adjustment has smaller adjustment steps and is more precise, requiring more adjustments than coarse adjustment. Compared to coarse adjustment, fine adjustment of the motor speed is more accurate and the speed regulation process is more efficient.

[0046] In the above optional embodiment, the first predetermined number of times and the second predetermined number of times may be the same or different. The stopping condition for fine-tuning the motor may be that the adjusted mixing speed is within the second speed threshold range, or the number of times the motor is fine-tuned is less than or equal to the second predetermined number of times, or whether the adjusted mixing speed is within the second speed threshold range together with the number of times of fine-tuning may be used as a basis for judging whether the fine-tuning is completed. When the stopping condition for fine-tuning the motor is that the adjusted mixing speed is within the second speed threshold range, the number of times of fine-tuning may be unlimited, and an unlimited number of adjustments may be made until the adjusted mixing speed is within the second speed threshold range, at which time the fine-tuning stops. When the stopping condition for fine-tuning the motor is that the number of times the motor is fine-tuned is less than or equal to the second predetermined number of times, if the second predetermined number of times is 10, that is, the number of times the motor is fine-tuned may be any one of 1 to 10 times, then the number of times the motor is fine-tuned may be 5 stops, 7 stops, or 10 stops. When the adjusted mixing speed is within the second speed threshold range, together with the number of fine adjustments, serves as a basis for determining whether fine adjustment is complete, fine adjustment of the motor may be stopped only when the number of times is within the second predetermined number and the adjusted mixing speed is also within the second speed threshold range. The above is only one example of fine adjustment of the motor. There are many other ways to fine-tune the motor, which are not listed here one by one. The first speed threshold range is larger than the second speed threshold range in order to make the adjusted mixing speed more accurate.

[0047] As an optional embodiment, fine-tuning the motor includes: obtaining a target speed for determining a second speed threshold range; obtaining a current mixing speed and current drive parameters of the motor before fine-tuning; obtaining a second speed deviation between the current mixing speed and the target speed within the second speed threshold range; and fine-tuning the motor based on the current drive parameters and the second speed deviation. Compared to not adjusting based on drive parameters and the speed deviation, fine-tuning based on the drive parameters and the speed deviation produces a more precise adjustment of the motor speed, resulting in a more efficient speed adjustment process.

[0048] In the above optional embodiment, for example, the minimum value of the above second speed threshold range can be the target speed of the second speed threshold range minus the adjustment allowable deviation, the maximum value of the second speed threshold range can be the target speed plus the adjustment allowable deviation, and the target speed of the second speed threshold range is 25r / min. For example, when the adjustment allowable deviation is 0.4r / min, the minimum value of the second speed threshold range at this time is 24.6r / min, and the minimum value of the second speed threshold range is 25.4r / min, that is, the second speed threshold range is 24.6r / min to 25.4r / min. If the current mixing speed is 30r / min, 30r / min is not within the second speed threshold range (24.6r / min to 25.4r / min). At this time, the motor needs to be fine-tuned. Subtracting the target speed 25r / min from the current mixing speed 30r / min, the second speed deviation is 5r / min. According to the second speed deviation of 5r / min at this time, the driving parameters of the current driving parameters are adjusted to obtain new driving parameters. The new driving parameters make the current mixing speed of the motor change finely towards the target speed to obtain a new mixing speed. At this time, the new mixing speed and the new driving parameters will be used as the current mixing speed and the current driving parameters for the next adjustment. The motor will continue to be fine-tuned until the absolute value of the second speed deviation is less than the allowable adjustment deviation, or the number of adjustments is less than or equal to the first predetermined number, and then the fine adjustment of the motor will be stopped.

[0049] As an optional embodiment, fine-tuning the motor based on the current drive parameters and the second speed deviation includes: obtaining a fine-tuning coefficient; and fine-tuning the motor based on the current drive parameters, the second speed deviation, and the fine-tuning coefficient. Using the fine-tuning coefficient allows for more accurate motor speed adjustment, higher adjustment precision, and greater speed regulation efficiency than not using the fine-tuning coefficient.

[0050] In the above optional embodiment, the product of the second speed deviation and the fine adjustment coefficient is calculated to obtain a third result, and the third result is added to the current drive parameter to obtain a fourth result, which serves as the new drive parameter of the motor. The new drive parameter causes the current mixing speed of the motor to vary finely toward the target speed, resulting in a new mixing speed. Through the above steps, the current drive parameter of the motor can be obtained, the current mixing speed can be obtained based on the current drive parameter, and the second speed deviation can be obtained based on the current mixing speed, thereby determining whether the fine adjustment of the motor is complete.

[0051] As an optional embodiment, the first predetermined number is less than or equal to the second predetermined number.

[0052] In the above optional embodiment, the first predetermined number and the second predetermined number can be determined through experience, or the accurate first predetermined number and the second predetermined number can be obtained through a large number of experiments. The maximum limit number of times for coarse adjustment and fine adjustment of the mixing speed of the motor can more accurately adjust the mixing speed of the motor, and the speed regulation process is more efficient.

[0053] As an optional embodiment, during the process of coarsely adjusting the motor, if the adjusted mixing speed is still not within the first speed threshold range after the number of coarse adjustments to the motor exceeds a third predetermined number, the motor is fine-adjusted; during the process of fine-adjusting the motor, if the adjusted mixing speed is still not within the second speed threshold range after the number of fine adjustments to the motor exceeds a fourth predetermined number, an alarm message is issued, wherein the alarm message indicates that the motor adjustment has failed.

[0054] In the above-described optional embodiment, when the motor has been coarsely adjusted a first predetermined number of times, and the motor's mixing speed is still within the first speed threshold range, the coarse adjustment may not be immediately stopped to enter fine adjustment, but the motor's mixing speed may continue to be adjusted for a third predetermined number of times, which is less than the first predetermined number of times. If the motor's mixing speed is within the first speed threshold range within the third predetermined number of times, the coarse adjustment is stopped and fine adjustment is entered.

[0055] In the above optional embodiment, after entering fine adjustment, when the number of times the motor performs fine adjustment reaches the second predetermined number, if the mixing speed of the motor is not yet within the second speed threshold range, the fine adjustment will not be stopped immediately, but the mixing speed of the motor will continue to be adjusted, and the number of adjustments will be the fourth predetermined number, which is less than the second predetermined number. If the mixing speed of the motor is within the second speed threshold range within the fourth predetermined number, the fine adjustment will be stopped and the adjustment will be successful; if the mixing speed of the motor is not within the second speed threshold range at the maximum number of the fourth predetermined number, the fine adjustment will also be stopped, the adjustment will fail, and an alarm message will be issued. By setting the third predetermined number and the fourth predetermined number, the adjustment will not be stopped immediately when the mixing speed of the motor is not successfully adjusted within the first predetermined number and the second predetermined number, but the mixing speed of the motor will be given an additional number of adjustments, which will better ensure that the mixing speed of the motor is successfully adjusted, and the speed regulation process will be more efficient.

[0056] By detecting the initial mixing speed of the motor, wherein the motor is used to drive the mixing machine to mix multiple materials; obtaining a pre-set first speed threshold range; when the initial mixing speed is not within the first speed threshold range, roughly adjusting the motor until the adjusted mixing speed is within the first speed threshold range, or the number of rough adjustments to the motor is less than or equal to a first predetermined number of times; and finely adjusting the motor until the adjusted mixing speed is within the second speed threshold range, or the number of fine adjustments to the motor is less than or equal to a second predetermined number of times, wherein the first speed threshold range includes the second speed threshold range. Based on first roughly adjusting the mixing speed of the motor and then finely adjusting the mixing speed of the motor, a technical effect of more accurately adjusting the mixing speed of the motor is achieved, thereby solving the technical problems of inaccurate motor speed adjustment and slow speed regulation efficiency in related technologies.

[0057] In the above embodiment, the mixing speed is detected by the optical coupling detection mixing mechanism baffle. When the mixing action is performed during the operation of the instrument, the mixing speed is judged. When the speed is not within the set threshold range, an alarm is issued to the user, and the mixing speed adaptive adjustment process is entered at a specific time when the instrument is running. The adaptive adjustment process is to give the target speed A (30r / min) of the adaptive adjustment and the adjustment allowable deviation ±δ (0.5r / min). That is, the adjustment is successful when the adjustment reaches the range of A±δ. First, coarse adjustment: judge the deviation D1 between the current speed and the target speed (D1=target speed A-current speed n), and automatically adjust the driving parameters of the driving motor according to D1, that is, the current driving parameters + K1*D1, (K1=80) so that the motor speed changes roughly towards the target value. During the process, when |D1|≤δ or the set repetition n (10) times is executed, the adaptive adjustment process is terminated and the fine adjustment process is entered. Fine tuning: Determine the deviation D2 between the speed after coarse tuning and the target speed, and automatically adjust the drive parameters of the drive motor according to D2, that is, the current drive parameters + K2*D2 (K2=10) (Note: K2 is smaller than K1), so that the motor speed changes finely towards the target value. Fine tuning is repeated at most m(40) times. During the fine tuning process, when |D2|≤δ, the adjustment is considered successful, the adaptive adjustment process is terminated, and the new motor parameters after adjustment are saved in the instrument. If the target speed range A±δ cannot be reached after performing n coarse tuning and m fine tuning, the adaptive adjustment fails, the motor does not update, and an alarm prompts the user.

[0058] FIG3 is a schematic diagram of a motor speed adjustment method provided according to an optional embodiment of the present application. As shown in FIG3 , the motor speed adjustment method includes the following steps:

[0059] Step 1, coarse adjustment of motor parameters, n = n-1, where n represents the number of coarse adjustments, and n-1 represents one adjustment and one reduction, and the number of adjustments is gradually reduced.

[0060] Step 2: Perform mixing and detect the rotation speed at the same time, that is, drive the motor to rotate and mix the various materials.

[0061] Step 3: Determine whether the speed is within the target range, or whether n is equal to 0. If the speed is not within the target range, or n is not equal to 0, execute step 1; if the speed is within the target range, or n is equal to 0, execute step 4.

[0062] Step 4, fine-tune the motor parameters, m=m-1, where m represents the number of fine-tuning times, and m-1 represents that the parameters are reduced by one adjustment each time, and the number is reduced gradually.

[0063] Step 5: Perform mixing and detect the rotation speed at the same time.

[0064] Step 6: Determine whether the speed is within the target range, or whether m is equal to 0. If the speed is not within the target range, or m is not equal to 0, execute step 4; if the speed is within the target range, or m is equal to 0, the speed regulation ends.

[0065] The above embodiment proposes a solution for automatic mixing adjustment and its intelligent application in instruments. Among them, the object of automatic adjustment can be a DC motor or a stepper motor. The speed detection method can be a detection solution of an optical coupler sensor + a baffle, or other speed detection methods. It can be used in a fully automatic immunoassay analyzer, which can perform quantitative or qualitative detection of target analytes such as antibodies and antigens contained in a blood sample to be tested. Usually, the sample to be tested and the reagent are distributed in an empty reactor, and after the steps of mixing, incubation, cleaning and separation, the signal reagent is distributed in the reactor to measure the light signal or electrical signal, thereby realizing the measurement and analysis of the target analyte contained in the sample to be tested. Among them, the sample and the reagent need to be mixed before incubation, and they also need to be mixed during the cleaning and separation process. The mixing effect directly affects the accuracy and precision of the test results. The existing mixing method is generally achieved by a motor driving the mixing mechanism to make the reaction container rotate along the axis or eccentrically rotate. Because materials and assembly processes cannot be perfectly controlled, the resistance of the mixing rotation mechanism varies, and the speed of the mixing mechanism can vary between machines, leading to inconsistent test results. Furthermore, over long-term testing, the mixing speed of the same instrument may change due to structural wear, increased resistance, and other factors, affecting test performance. Existing technologies either fail to monitor the mixing speed, lack automatic adjustment schemes, or employ overly complex adaptive adjustment schemes.
