[0005] In a first aspect, an embodiment of the present application provides a method for test tube oscillation, which is applied to a test tube oscillation device, and the method comprises: Detect the first quality of the liquid in the test tube; The test tube oscillation device is started in a first oscillation mode and detects first force feedback information; wherein the first oscillation mode refers to a default oscillation mode of the test tube oscillation device for testing, the first oscillation mode includes a first oscillation frequency and a first oscillation amplitude, and the first force feedback information refers to information related to the magnitude and time of the force between the test tube and the test tube slot during the test tube oscillation process of the test tube oscillation device in the first oscillation mode; A first impact ratio is obtained according to the first force feedback information and the first mass; wherein the first impact ratio refers to the ratio of the maximum impact force of the liquid on the test tube wall to the mass of the liquid during the test tube oscillation process of the test tube oscillation device in the first oscillation mode; A first oscillation acceleration is obtained according to the first oscillation frequency and the first oscillation amplitude; wherein the first oscillation acceleration refers to the acceleration of the ideal fluid when the test tube oscillation device oscillates the test tube loaded with the ideal fluid in the first oscillation mode; The oscillation mode of the test tube oscillation device is adjusted according to the first impact ratio and the first oscillation acceleration.

First, the first mass of the liquid in the test tube is detected. The present application determines whether the oscillation mode of the test tube oscillation device is appropriate by detecting the force of the liquid in the test tube impacting the test tube. The mass of the liquid directly affects the force of the liquid in the test tube impacting the test tube.

[0020] In the related art, the mixing degree of liquid or solid in the test tube is often improved by improving and using different oscillation methods, such as using multi-dimensional oscillation methods, etc., which can effectively improve the mixing degree of the liquid. However, these methods only use fixed oscillation steps, and neither consider the different viscosities of different liquids nor whether the liquids oscillate synchronously (synchronous oscillation is similar to resonance, and when the oscillation frequency of the liquid is equal to the oscillation frequency of the oscillation device, it is called synchronous oscillation). There is no dynamic adjustment of the oscillation steps for liquids of different viscosities, and can only produce a better mixing effect on liquids with a small range of viscosities.
[0021] To solve the above problems, an embodiment of the present application provides a method for test tube oscillation. In the method, first, the first mass of the liquid in the test tube is detected. The present application determines whether the oscillation mode of the test tube oscillation device is appropriate by detecting the force of the liquid in the test tube impacting the test tube, and the mass of the liquid directly affects the force of the liquid in the test tube impacting the test tube. Therefore, in this step, the first mass of the liquid is detected before the test tube oscillation device oscillates, which can improve the accuracy of the first mass measured. Secondly, the test tube oscillation device is started in the first oscillation mode and the first force feedback information is detected. In this step, after the test tube oscillation device is started in the default first oscillation mode, the force feedback of the liquid on the test tube is detected, and the first force feedback information is used to reflect the oscillation state of the liquid. Subsequently, the first impact ratio is obtained according to the first force feedback information and the first mass. The first impact ratio is obtained in this step. The first impact ratio is a scalar, which can not only represent the impact force of the liquid on the test tube, but also does not need to consider the mass of the liquid. Then, according to the first oscillation frequency and the first oscillation amplitude, the first oscillation acceleration is obtained. In this step, the first oscillation acceleration is obtained. The first oscillation acceleration is the acceleration of the liquid in the oscillation process under ideal conditions, and can be used as a detection threshold for judging the oscillation state of the liquid. Finally, according to the first impact ratio and the first oscillation acceleration, the oscillation mode of the test tube oscillation device is adjusted. In this step, the oscillation state of the liquid in the test tube can be judged according to the first oscillation acceleration and the first impact ratio, and then the oscillation mode of the test tube oscillation device is adjusted according to the oscillation state of the liquid. In the method provided by the present application, the test tube oscillation device first oscillates the test tube in the default first oscillation mode, detects the force feedback information between the test tube and the test tube slot, and analyzes the force feedback information to determine whether the liquid in the test tube oscillates synchronously (synchronous oscillation refers to resonance with the test tube oscillation device), and then adjusts the oscillation mode of the test tube oscillation device according to the oscillation result of the liquid, and can cyclically obtain the impact ratio and the oscillation acceleration and cyclically adjust all steps of the oscillation mode to achieve dynamic adjustment of the oscillation mode of the test tube oscillation device, which can solve the problem that the existing test tube oscillation method does not dynamically adjust the oscillation step for liquids of different viscosities, resulting in only a small range of viscosity liquids can produce a better mixing effect.
[0022] The method for test tube oscillation provided in the embodiment of the present application can be applied to a test tube oscillation device. In this case, the test tube oscillation device is the executor of the method for test tube oscillation provided in the embodiment of the present application. The embodiment of the present application does not impose any restrictions on the specific type of the test tube oscillation device.
[0023] For example, the test tube oscillation device may include a detection device, an oscillation device, and a control device that is communicatively connected to the detection device and the oscillation device. The detection device may be a piezoelectric sensor, and the piezoelectric sensor is located in the test tube slot of the oscillation device. When the test tube is inserted into the test tube slot of the oscillation device, the test tube and the test tube slot clamp and fit tightly against the piezoelectric sensor, and the piezoelectric sensor can detect the force between the test tube and the test tube slot. The oscillation device may be a variable frequency and torque eccentric wheel test tube oscillation device, and the frequency conversion function belongs to the prior art. The torque conversion function can be achieved by using an electromagnetically locked eccentric wheel with a variable radius. The control device can control the detection device to detect the first mass, and can also control the detection device to detect the first force feedback information. The control device can control the oscillation device to oscillate the test tube at different oscillation frequencies and oscillation amplitudes.
[0024] The control device can be a single chip microcomputer, a mobile phone, a tablet computer, a notebook computer, a desktop computer, a computer, etc.
[0025] In order to better understand the method for test tube oscillation provided in the embodiment of the present application, the specific implementation process of the method for test tube oscillation provided in the embodiment of the present application is exemplarily introduced below.
[0026] Figure 1 A schematic flow chart of a method for test tube oscillation provided in an embodiment of the present application is shown, and the method for test tube oscillation comprises: S100, detecting the first mass of the liquid in the test tube.
[0027] It can be understood that the gravity of the test tube and the liquid in the test tube can be detected by a piezoelectric sensor, and then divided by the acceleration of gravity to obtain the mass of the test tube and the liquid in the test tube. A test tube of fixed specifications can be used to obtain a fixed mass of the test tube, and the first mass is equal to the mass of the test tube and the liquid in the test tube minus the mass of the test tube.
[0028] With this arrangement, the first quality can be detected quickly and stably.
[0029] S200, the test tube oscillation device is started in a first oscillation mode, and first force feedback information is detected. The first oscillation mode refers to a default oscillation mode used by the test tube oscillation device for testing, the first oscillation mode includes a first oscillation frequency and a first oscillation amplitude, and the first force feedback information refers to information related to the magnitude and time of the force between the test tube and the test tube slot during the test tube oscillation process of the test tube oscillation device in the first oscillation mode.
[0030] It can be understood that first, the test tube oscillation device is allowed to oscillate the test tube in a default oscillation mode. When the oscillation frequency of the test tube oscillation device reaches the first oscillation frequency and the oscillation amplitude reaches the first oscillation amplitude, it means that the test tube oscillation device has oscillated stably. Subsequently, a piezoelectric sensor can be placed between the test tube and the test tube slot to detect the first force feedback information. The piezoelectric sensor can be one or multiple piezoelectric sensors can be evenly and symmetrically placed. The two-dimensional force-time information detected by the piezoelectric sensor is the first force feedback information.
[0031] With such an arrangement, the first force feedback information is detected after the test tube oscillation device oscillates stably, so that the quality of the measured first force feedback information can be improved, and the first force feedback information can reflect whether the liquid oscillates synchronously.
[0032] S300, obtaining a first impact ratio according to the first force feedback information and the first mass, wherein the first impact ratio refers to the ratio of the maximum impact force of the liquid on the test tube wall to the mass of the liquid during the test tube oscillation process of the test tube oscillation device in the first oscillation mode.
[0033] It can be understood that during the test tube oscillation process, the shear force between the liquids causes the liquids to disperse and mix, and the shear force mainly comes from the collision between the liquid and the test tube wall, which means that under the conditions of the same test tube and liquid, the greater the impact force between the liquid and the test tube wall, the easier it is for the liquid in the test tube to mix. This result is in line with common sense. The impact force between the liquid and the test tube wall is also directly proportional to the mass of the liquid. If the influence of the liquid mass is not excluded, the test tube oscillation device will also adopt different oscillation modes when oscillating the same liquid due to the different mass of the liquid, which deviates from the purpose of adjusting different oscillation modes according to liquids of different viscosities in this application. Therefore, the representative impact force in the first force feedback information is divided by the mass of the liquid to obtain the first impact ratio, which can indicate the intensity of the oscillation of the liquid in the test tube. The representative impact force in the first force feedback information can be the peak force in an oscillation cycle.
[0034] Such a setting can eliminate the influence of the mass of the liquid, which is conducive to allowing the test tube oscillation device to adjust different oscillation modes according to liquids of different viscosities.
[0035] In a possible implementation, in step S300, obtaining a first impact ratio according to the first force feedback information and the first mass includes: S310, obtaining a target force from the first force feedback information, wherein the target force refers to the impact force of the liquid on the test tube in the current oscillation cycle in the first force feedback information.
[0036] It can be understood that within one oscillation cycle, if the liquid and the test tube oscillation device oscillate synchronously, then ideally there will be one and only one obvious peak in the first force feedback information (at this time most of the liquid just impacts the test tube wall where the piezoelectric sensor is located), and the target force is the peak force. At this time, the target force is the most representative impact force of the current oscillation cycle in the first force feedback information.
[0037] With such an arrangement, the magnitude of the peak force can effectively represent the magnitude of the impact force of the liquid in the test tube during one oscillation cycle.
[0038] In a possible implementation, in step S310, obtaining the target force from the first force feedback information includes: S311, obtaining the current oscillation period.
[0039] It can be understood that the oscillation speed of the test tube oscillation device sometimes changes, so the oscillation period at different times is also different. The instantaneous oscillation frequency of the test tube oscillation device can be monitored at all times, 1 / instantaneous oscillation frequency = instantaneous oscillation period, to obtain the current oscillation period.
[0040] With such settings, the actual test tube oscillation process is not an ideal physical situation and there will be various influencing factors. Therefore, taking only the peak force as the most representative impact force of the current oscillation period in the first force feedback information will produce a large system error. Therefore, reducing this system error through data processing and obtaining the current oscillation period is the first step in data processing.
[0041] S312: Obtain current period force information according to the first force feedback information, wherein the current period force information is function information of force and time in the current oscillation period.
[0042] It can be understood that the first force feedback information includes the force information of all oscillation cycles of the test tube oscillation device from the start to the current, from which the current cycle force information of the current oscillation cycle is obtained. The current cycle force information can be a function of force-time, and the time interval of the function is the current oscillation cycle.
[0043] By setting it in this way, useless force information of other oscillation periods is removed, which can improve the efficiency of data processing.
[0044] S313, obtaining a target force according to the force information of the current cycle and the first interval, wherein the value of the first interval is a preset constant multiplied by the current oscillation period, and the center point of the first interval is the maximum force value in the force information of the current cycle.
[0045] It can be understood that the coordinates of the peak force point are found in the force information of the current cycle, t1 is set as the time coordinate of the peak point, and the definite integral is calculated for the force information of the current cycle. The integral range of the definite integral is the first interval. The first interval is centered on t1, and the interval size is a preset constant ratio of the current oscillation period. For example, the interval size can be the oscillation period / 4, and the target force is equal to the integral result divided by the interval size, which means that the target force is equal to the average force of the force information of the current cycle in the first interval. There is also a possibility that the range of the first interval may exceed the value range of the force information of the current cycle. The range of the first interval can be narrowed so that the range of the first interval is within the value range of the force information of the current cycle. The value range of the force information of the current cycle can also be expanded from the first force feedback information so that the value range of the force information of the current cycle includes the range of the first interval.
[0046] In this way, the definition of the target force is changed from one point to the average value of the force in the first interval around the peak point. This can prevent the peak point force from being accidentally too high or too low, which in turn causes the result of the first impact ratio to fluctuate too much, and is beneficial to improving the stability and accuracy of the first impact ratio.
[0047] S320: Divide the target force by the first mass to obtain a first impact ratio.
[0048] It can be understood that the first impact ratio is obtained by dividing the obtained target force by the first mass.
[0049] With this setting, an accurate first impact ratio can be obtained quickly.
[0050] S400: Obtain a first oscillation acceleration according to the first oscillation frequency and the first oscillation amplitude, wherein the first oscillation acceleration refers to the acceleration of the ideal fluid when the test tube oscillation device oscillates the test tube loaded with the ideal fluid in the first oscillation mode.
[0051] It can be understood that during the test tube oscillation, the liquid in the test tube either oscillates synchronously with the test tube or cannot oscillate synchronously due to its high viscosity. When the liquid oscillates synchronously, it can be calculated according to the formula ( is the oscillation angular velocity, = first oscillation frequency / 2π, r refers to the first oscillation amplitude) to calculate the first oscillation acceleration of the synchronously oscillating liquid; if the liquid does not oscillate synchronously, the acceleration of the liquid in the test tube will be less than the first oscillation acceleration, and the first oscillation acceleration can be used to assist in determining whether the liquid oscillates synchronously.
[0052] With such an arrangement, the first impact ratio and the first oscillation acceleration can be combined to determine the oscillation state of the liquid in the test tube so as to adjust the oscillation mode.
[0053] S500: adjusting the oscillation mode of the test tube oscillation device according to the first impact ratio and the first oscillation acceleration.
[0054] It is understandable that the liquid in the test tube will produce an impact force on the test tube wall. (m is equal to the mass of the liquid, a is equal to the acceleration of the liquid), and the first impact ratio = F / m, so ideally, when the first impact ratio is greater than or equal to the first oscillation acceleration, it means that the liquid in the test tube oscillates synchronously, and if the first impact ratio is less than the first oscillation acceleration, it means that the liquid in the test tube does not oscillate synchronously, but in reality, the comparison between the first impact ratio and the first oscillation acceleration needs to be multiplied by a constant to cope with the consumption of internal energy, such as when the first impact ratio is greater than or equal to a×first oscillation acceleration, it means that the liquid in the test tube oscillates synchronously, and a is less than 1. When the liquid oscillates synchronously, it means that the oscillation mode of the test tube oscillation device can also speed up the oscillation frequency; if the liquid does not oscillate synchronously, it means that the oscillation mode of the test tube oscillation device needs to slow down the oscillation frequency.
[0055] With such an arrangement, the oscillation mode of the test tube oscillation device can be adjusted according to liquids of different viscosities.
[0056] In a possible implementation, in step S500, adjusting the oscillation mode of the test tube oscillation device according to the first impact ratio and the first oscillation acceleration includes: S510: When the first impact ratio is less than or equal to the first threshold multiplied by the first oscillation acceleration, a first adjustment is performed, wherein the first adjustment refers to reducing the oscillation frequency of the test tube oscillation device and increasing the oscillation amplitude of the test tube oscillation device so that the product of the oscillation frequency of the test tube oscillation device and the oscillation amplitude of the test tube oscillation device is a constant value.
[0057] It can be understood that the first threshold is used to balance the energy loss such as internal energy. The first threshold is less than 1. The diameter of the test tube will affect the amount of internal energy generated when the liquid oscillates. The value of the first threshold under different test tube diameters can be determined experimentally. The experiment can be to oscillate a fixed liquid in a fixed oscillation mode (to ensure that the liquid is synchronously oscillating). The variable is the test tube diameter, and the detection quantity is the impact ratio and the oscillation acceleration. The ratio of the two detection quantities is the value of the first threshold. When the first impact ratio is less than or equal to the first threshold multiplied by the first oscillation acceleration, the liquid in the test tube does not oscillate synchronously. At this time, the first adjustment is applied. The first adjustment is to uniformly reduce the oscillation frequency of the test tube oscillation device to ensure the linear change of the oscillation mode, but according to It can be seen that when the oscillation frequency is uniformly reduced, the acceleration of the liquid changes nonlinearly, so r is uniformly increased, so that is a fixed value, then the oscillation frequency and the acceleration of the liquid change linearly and uniformly.
[0058] Such an arrangement enables the oscillation frequency and the acceleration of the liquid to change linearly and evenly, which can make the adjustment process of the test tube oscillation device more regular and controllable, and is conducive to improving the effectiveness of the test tube oscillation device.
[0059] Optionally, in step S510, the method further includes: S511: When the first impact ratio is less than or equal to the first threshold multiplied by the first oscillation acceleration, the first oscillation acceleration is divided by the first impact ratio to obtain a second ratio.
[0060] It can be understood that whether the first impact ratio is within the range of (0, a] (a=first threshold multiplied by first oscillation acceleration) is determined. When it is within the range of (0, a], it means that the test tube oscillation device will perform the first adjustment. However, in the range of (0, a], when the first impact ratio is close to 0 and close to a, if the same first adjustment is performed, the adjustment process error will be too large and the dynamic adjustment requirement cannot be met. Therefore, the first oscillation acceleration is divided by the first impact ratio to obtain the second ratio. The second ratio is used to represent the specific range between the first oscillation acceleration and the first impact ratio.
[0061] Such an arrangement makes the adjustment process of the test tube oscillation device more reasonable.
[0062] S512: When the second ratio is less than or equal to a second threshold, the first adjustment is used to instruct the oscillation frequency of the test tube oscillation device to decrease at a first rate, wherein the second threshold is greater than 0 and less than the first threshold.
[0063] It can be understood that the second threshold can be a variable and can be equal to 0+C1 / 2 (C1 refers to the first threshold). When the second ratio is less than or equal to the second threshold, it means that the gap between the first oscillation acceleration and the first impact ratio is large, so the first adjustment can reduce the oscillation frequency at a larger first rate.
[0064] Such an arrangement makes the adjustment process of the test tube oscillation device more reasonable.
[0065] S513: When the second ratio is greater than the second threshold, the first adjustment is used to instruct the oscillation frequency of the test tube oscillation device to decrease at a second rate, wherein the second rate is less than the first rate.
[0066] It can be understood that when the second ratio is greater than the second threshold, it means that the gap between the first oscillation acceleration and the first impact ratio is smaller, so the first adjustment can reduce the oscillation frequency at a smaller first rate.
[0067] Such an arrangement makes the adjustment process of the test tube oscillation device more reasonable.
[0068] S520, when the first impact ratio is greater than the first threshold multiplied by the first oscillation acceleration, a second adjustment is performed, wherein the second adjustment refers to increasing the oscillation frequency of the test tube oscillation device and reducing the oscillation amplitude of the test tube oscillation device so that the product of the oscillation frequency of the test tube oscillation device and the oscillation amplitude of the test tube oscillation device is a constant value.
[0069] It can be understood that when the first impact ratio is greater than the first threshold multiplied by the first oscillation acceleration, the liquid in the test tube oscillates synchronously, and the second adjustment is applied at this time. The second adjustment increases the oscillation frequency of the test tube oscillation device at a uniform speed to ensure a linear change of the oscillation mode, but according to It can be seen that when the oscillation frequency increases at a uniform speed, the acceleration of the liquid changes nonlinearly, so r is uniformly reduced, so that is a fixed value, then the oscillation frequency and the acceleration of the liquid are both linearly and uniformly changed. And the oscillation frequency of low-viscosity liquids is backward compatible, for example, water and honey, at the frequency at which honey can oscillate synchronously, water can also oscillate synchronously, but not vice versa. Therefore, the second adjustment cannot be subdivided like the first adjustment in steps S511, S512 and S513. The second adjustment increases the oscillation frequency at a fixed rate.
[0070] Such an arrangement enables the oscillation frequency and the acceleration of the liquid to change linearly and evenly, which can make the adjustment process of the test tube oscillation device more regular and controllable, and is conducive to improving the effectiveness of the test tube oscillation device.
[0071] Optionally, the method further includes: S610, after the test tube oscillation device adjusts the oscillation mode for a first time, execute a first operation, and repeat the first operation at a first time interval, wherein the first time is N oscillation cycles, N is a fixed constant, and the oscillation cycle is variable, and the first operation is used to instruct the test tube oscillation device to adjust the current oscillation mode according to the currently obtained impact ratio and oscillation acceleration.
[0072] It can be understood that the first operation is both the step of adjusting the oscillation mode and all the preceding steps. The test tube oscillation device adjusts the oscillation mode once every N oscillation cycles to achieve dynamic adjustment of the oscillation mode of the test tube oscillation device.
[0073] This setting can adapt to liquids whose viscosity changes during the oscillation process, such as partially coagulated blood, etc.
[0074] Optionally, the test tube oscillating device oscillates in a circular oscillation mode, and the oscillation direction is reversed at fixed time intervals.
[0075] It can be understood that circular oscillation refers to an oscillation method that causes the liquid in the test tube to rotate to form a vortex. This method can provide stable force feedback information during the oscillation process, and can reverse the oscillation direction to increase the shear force inside the liquid to fully mix the liquid.
[0076] With such arrangement, the circular oscillation mode can have stable force feedback information, which is beneficial to improving the accuracy of the test tube oscillation device.
[0077] Optionally, when the test tube oscillation device is started, the oscillation frequency gradually increases from zero, and the oscillation amplitude gradually decreases from a maximum value, and when the oscillation frequency of the test tube oscillation device increases from zero and stabilizes to the first oscillation frequency, the first force feedback information is detected.
[0078] It can be understood that the startup process of the test tube oscillation device takes some time, during which the oscillation frequency and oscillation amplitude of the test tube oscillation device are constantly changing. Therefore, it is set that the force feedback information is detected after the oscillation frequency of the test tube oscillation device is stable, and the oscillation amplitude is at the maximum value when the test tube oscillation device is not started.
[0079] Such an arrangement can improve the accuracy of the test tube oscillation device.
[0080] Optionally, the test tube oscillation device includes three power levels: high, medium and low. When in the high power level, the product of the oscillation frequency and the oscillation amplitude of the test tube oscillation device is a first constant value. When in the medium power level, the product of the oscillation frequency and the oscillation amplitude of the test tube oscillation device is a second constant value. When in the low power level, the product of the oscillation frequency and the oscillation amplitude of the test tube oscillation device is a third constant value. The first constant value is greater than the second constant value, and the second constant value is greater than the third constant value.
[0081] It can be understood that different power gears can be set for the test tube oscillation device to cope with different mass liquid mixing tasks. It can be seen that the power of the test tube oscillation device is reflected in the oscillation frequency and the oscillation amplitude. When the power of the test tube oscillation device is higher, the product of the oscillation frequency and the oscillation amplitude of the test tube oscillation device is also larger. Therefore, in the case of three power gears, the product of the oscillation frequency and the oscillation amplitude of the test tube oscillation device is respectively the first fixed value, the second fixed value and the third fixed value, and the first fixed value is greater than the second fixed value, and the second fixed value is greater than the third fixed value.
[0082] This setting can cope with the mixing tasks of different amounts of liquids.
