Any modification, replacement and the improvement of component and algorithm.In the the accompanying drawings and the following description, well known structure and skill is not shown
Art is unnecessary fuzzy to avoid causing the present invention.
It is referred in the application described in the expression such as " one embodiment ", " embodiment ", " each embodiment ", " example "
(one or more) embodiment or example may include specific feature, structure or feature, but not be each embodiment or example
It must include specific feature, structure or the feature.Moreover, the phrase " in one example " reused is not necessarily referring to together
One example, although it may refer to same example.
It is provided in an embodiment of the present invention to take liquid test method, device, liquid equipment and storage medium is taken to can be applied to biology, doctor
In the scene in the fields such as, chemistry, physics needing that liquid is taken to be tested or tested.Fig. 1 is that one kind is answered in the embodiment of the present invention
Use schematic diagram of a scenario.As shown in Figure 1, the probe of liquid test device is taken to move up and down under the control for taking liquid test circuit, and inhale
Take the liquid (taking liquid) held in liquid container.During once taking liquid, probe is gradually reduced above liquid, until visiting
A part of needle submerges liquid, and probe stop motion carries out taking liquid.When reaching the scheduled liquid for taking liquid duration or acquirement
Amount reaches predetermined amount, then probe terminates to take liquid, and is gradually increasing, until being reset to position when liquid process being taken to start where probe
It sets.
During taking liquid, take liquid test device can be according to the variation of probe signals, to judge whether probe touches liquid
Face.During probe is not in contact with to liquid level, probe always in a certain medium (can be air) in embodiments of the present invention
Movement, probe signals are unchanged or variation is smaller.Before leaving liquid level to probe after probe contacts liquid level, the head one of probe
Directly stop in a certain medium (in embodiments of the present invention can be liquid) or movement, probe signals are unchanged or variation compared with
It is small.
Never touch liquid level to during touching liquid level in probe, due to probe head from a certain medium (
Can be air in the embodiment of the present invention) enter another transfer (in embodiments of the present invention can be liquid), probe signals can be unexpected
Large change (mutating) occurs, generates larger fluctuation.But due to the influence of extraneous factor, for example, bubble, electrostatic,
Electromagnetic interference, distribution capacity etc. can also cause probe signals and large change (mutating) occur suddenly, generate larger wave
It is dynamic.Under the influence of extraneous factor, probe can also may also be mistaken for probe contact liquid level not in contact with to liquid level.Erroneous judgement occurs
Afterwards, probe starts to take liquid not in contact with liquid level, leads to that liquid is taken to fail.Alternatively, since probe enters the distance of liquid level
It is mismatched with scheduled liquid-taken amount, so that causing to take liquid insufficient taking liquid process middle probe to be detached from liquid level.Taking liquid deficiency is to take liquid
A kind of embodiment of failure.
In one example, probe signals, which mutate, can be embodied in the frequency of oscillation mutation of probe signals.
For example, Fig. 2 is a kind of in the embodiment of the present invention frequency of oscillation of probe signals and the relation curve of time during liquid to be taken to illustrate
Figure.As shown in Fig. 2, by taking noise is extraneous factor as an example.Noise will lead to frequency of oscillation mutation.Probe enters liquid from air
Body and probe enter air from liquid and will lead to frequency of oscillation mutation.Therefore, noise and liquid process middle probe is taken to take
Liquid is successfully difficult to differentiate between.
Fig. 3 is a kind of in the embodiment of the present invention to take the variable quantity of the frequency of oscillation of probe signals and the pass of time during liquid
It is curve synoptic diagram.As shown in figure 3, during taking liquid successfully once to take liquid, when probe contacts liquid level, the vibration of probe signals
The variable quantity for swinging frequency mutates.Probe enters liquid level and carries out during taking liquid, the change of the frequency of oscillation of probe signals
Change amount is gradually reduced, until zero.When probe leaves liquid level, the variable quantity of the frequency of oscillation of probe signals occurs prominent again
Become.During probe leaves liquid level rising reset, the variable quantity of the frequency of oscillation of probe signals is gradually reduced, until zero.
Probe will do it during taking liquid takes whether liquid successfully determines, but can be obtained by above description, might have outer
Boundary's factor has an impact the signal of the probe of acquisition, so as to cause liquid will be taken unsuccessfully to be mistaken for taking liquid success.Of the invention real
Apply in example, by probe once take liquid during determine take liquid be successfully known as " default probe once take liquid during take liquid at
Function ".It is provided in an embodiment of the present invention to take liquid test side in the case where defaulting probe and taking the successful situation of liquid during once taking liquid
Method, device, equipment and storage medium can take liquid successfully to determine to verify to probe during this time taking liquid, thus
Determine that default probe takes liquid success whether correct during once taking liquid.And then it improves and determines to take liquid whether successfully accurate
Property, it reduces and determines to take the whether successful False Rate of liquid.
Fig. 4 is a kind of flow chart for taking liquid test method in the embodiment of the present invention.As shown in figure 4, taking liquid test method packet
Step S101 is included to step S104.
In step s101, in the case where defaulting probe and taking the successful situation of liquid during once taking liquid, probe is controlled to nothing
Liquid container discharges the liquid got during once taking liquid.
In the case where defaulting probe and taking the successful situation of liquid during once taking liquid, the liquid that takes liquid test device that can will get
Release, with pending experiment.In embodiments of the present invention, it can use a no liquid container, control probe discharges the liquid got
Into no liquid container.It should be noted that before probe does not discharge the liquid got also, no liquid in the no liquid container
In the presence of.For example, no liquid container can be empty container before probe does not discharge the liquid got also.For example, no liquid container
For an empty beaker or an empty test tube.
In the case where once liquid process being taken to terminate and default and take the successful situation of liquid, controls probe and vacantly released into no liquid container
Tapping body.After guaranteeing that probe releases the liquid got, probe is not contacted with the liquid in no liquid container.
If probe takes liquid success during this time taking liquid really, probe has been drawn to liquid.In probe to aneroid
After the liquid that the release of body container is got, the liquid of probe release got is contained in no liquid container.
If probe will take liquid to be unsuccessfully mistaken for taking liquid success during this time taking liquid, probe is not drawn to liquid.
After the liquid that probe is got to the release of no liquid container, still without liquid in no liquid container.
Alternatively, probe may be drawn if probe will take liquid to be unsuccessfully mistaken for taking liquid success during this time taking liquid
Liquid has been arrived, but has not been drawn to the liquid for meeting expectation liquid-taken amount.After the liquid that probe is got to the release of no liquid container, nothing
The amount of liquid in liquid container can not reach desired liquid-taken amount.
In step s 102, control probe carries out liquid level test in no liquid container.
Control probe carries out liquid level test in no liquid container, is equivalent to and takes liquid to take whether liquid succeeds in the process to primary
Verifying.Specifically, taking the control probe decline of liquid test device after the liquid that probe is got to the release of no liquid container.For
Guarantee the accuracy of liquid level test, controllable manufacturing probe slowly declines.During probe decline, it can repeatedly obtain probe and exist
Measurement parameter in no liquid container.And measurement of comparison variable quantity and test judgement threshold value.
Wherein, measurement variable quantity is the variable quantity of the measurement parameter currently obtained and the last measurement parameter obtained.It needs
It is noted that in the present embodiment, measurement variable quantity is positive value.For example, the survey that measurement variable quantity concretely currently obtains
Measure the absolute value of the difference of parameter and the last measurement parameter obtained.Test judgement threshold value is to limit whether probe touches liquid level
Boundary value, can be preset.Specifically, test judgement threshold value can be set according to operative scenario or work requirements, herein not
Limitation.
In one example, the period of measurement parameter of the settable acquisition probe in no liquid container, such as setting obtain
The period for taking measurement parameter is 10 milliseconds, then during taking liquid, every 10 milliseconds, takes liquid test device to obtain a probe and exist
Measurement parameter in no liquid container.
Above-mentioned measurement parameter is the parameter for causing probe signals to change.For example, capacitor, resistance, inductance, pressure, probe are believed
Number frequency of oscillation in it is one or more.During probe enters liquid from air, the capacitor of probe, resistance, inductance,
Pressure can mutate, and the capacitor of probe, resistance, inductance, pressure mutates can be embodied as the oscillation of probe signals
Frequency mutates.For the ease of hourly observation and judgement, the frequency of oscillation of probe signals can be monitored and be obtained.Than
Such as, can variation according to RC oscillator principle by probe relative to the value of the capacitor on ground, be converted into and be easier to monitored probe
The frequency of oscillation of signal or charge and discharge time in the cycle of oscillation of probe signals, capacitor are inversely proportional with frequency of oscillation.For another example,
Can variation according to LC oscillator principle by probe relative to the value of the capacitor on ground, be converted into and be easier to monitored probe signals
Frequency of oscillation or probe signals cycle of oscillation in the charge and discharge time.
In step s 103, if probe is touching liquid level, verifying spy within the scope of no liquid container bottom preset height
Needle takes liquid success during once taking liquid.
Wherein, no liquid container bottom is the bottom end of no liquid container.Preset height range takes liquid based on the expectation of probe
It measures.The liquid containing of desired liquid-taken amount can be calculated in nothing according to the area of desired liquid-taken amount and no liquid container bottom
Accessible height in liquid container.Preset height range includes it is expected that the liquid containing of liquid-taken amount is reachable in no liquid container
The height arrived.
In one example, can using the liquid containing of desired liquid-taken amount in no liquid container accessible height as pre-
If the central value of altitude range, certain departure can be taken respectively in central value augment direction and reduction direction, to be formed pre-
If altitude range.For example, central value is set as 1 centimetre, then it is each to the direction greater than 1 centimetre and the difference of the direction less than 1 centimetre
From the departure for going 0.2 centimetre, obtaining preset height range is 0.8 centimetre to 1.2 centimetres.
In another example, can using the liquid containing of desired liquid-taken amount in no liquid container accessible height as
The maximum value of preset height range, to form preset height range.For example, the liquid containing of expectation liquid-taken amount holds in no liquid
Accessible height is 1 centimetre in device, then preset height range is 0 to 1 centimetre.
Probe is touching liquid level within the scope of no liquid container bottom preset height, then it represents that probe is once taking liquid mistake
Really liquid success is taken in journey.And probe discharges the liquid got into no liquid container, meets so that existing in no liquid container
Take the liquid of liquid success conditions.Therefore, it may be verified that probe takes liquid success really during once taking liquid, during once taking liquid
Whether judgement takes liquid to succeed, and there is no judge by accident.
In one example, if liquid level test is realized by measurement of comparison variable quantity and test judgement threshold value.If then probe
When within the scope of no liquid container bottom preset height, measurement variable quantity is greater than test judgement threshold value, it may be verified that probe is one
It is secondary that liquid is taken to take liquid success really in the process.
For example, if preset height range is 0.8 centimetre to 1.2 centimetres.Probe apart from 0.8 centimetre of no liquid container bottom extremely
Measurement variable quantity in the range of 1.2 centimetres is 0.2MHz (megahertz), and test judgement threshold value is 0.019MHz.Due to 0.2MHz
> 0.19MHz, therefore verify probe and take liquid success really during once taking liquid.
During probe contacts liquid level not in contact with liquid level to probe, the signal of probe can mutate.Specifically, table
Now mutate for the variable quantity of measurement parameter.Here " mutation " refers to that whithin a period of time measurement parameter increases or drop
Low amount is more than threshold value.Therefore, if measurement variable quantity is greater than test judgement threshold value, under can determine probe in no liquid container
In capable process, probe completes the movement for entering liquid from air, thus verify probe once take liquid during take liquid at
Function.
In step S104, if probe, not in contact with liquid level is arrived, is verified within the scope of no liquid container bottom preset height
Probe takes liquid to fail during once taking liquid.
Probe within the scope of no liquid container bottom preset height not in contact with arriving liquid level, then it represents that probe is once taking liquid
Liquid is taken to fail in the process, probe does not get liquid or probe takes liquid insufficient.Probe can not be released into no liquid container
Liquid, no liquid container still maintain the state of no liquid.Alternatively, probe can not be released into no liquid container it is enough
Liquid, the height of the liquid in no liquid container is outside preset height range.It therefore, can be by probe apart from no liquid container
Not in contact with liquid level is arrived within the scope of the preset height of bottom, verifying probe takes liquid to fail during once taking liquid.During once taking liquid
Judgement takes whether liquid is successfully judged by accident.
In one example, if liquid level test is realized by measurement of comparison variable quantity and test judgement threshold value.If in distance
Measurement of comparison variable quantity and test judgement threshold value when within the scope of no liquid container bottom preset height, measurement variable quantity are less than or equal to
Test judgement threshold value, it may be verified that probe takes liquid to fail during once taking liquid.
For example, if preset height range is 0.8 centimetre to 1.2 centimetres.Probe apart from 0.8 centimetre of no liquid container bottom extremely
Measurement variable quantity in the range of 1.2 centimetres is 0.02MHz (megahertz), and test judgement threshold value is 0.019MHz.Due to
0.02MHz < 0.19MHz, therefore verify probe and take liquid to fail during once taking liquid, that is to say, that once taking liquid process
It is successfully erroneous judgement that middle judgement, which takes liquid,.
In embodiments of the present invention, after taking liquid process, the liquid got during liquid will be taken to discharge to no liquid
In container, liquid level test is carried out according to the no liquid container for discharging liquid to probe, takes whether liquid takes liquid in the process to verify
Success.It, can be to taking liquid to take whether liquid successfully carries out more accurate judgement in the process, so that improving judgement takes liquid by verifying
Whether successful accuracy, reduce judgement and take the whether successful False Rate of liquid.Moreover, in embodiments of the present invention, and be not required to
Additionally to increase new device in taking liquid test device.That is, guaranteeing not increasing to take liquid test device complexity
On the basis of, it can be improved judgement and take the whether successful accuracy of liquid, reduce judgement and take the whether successful False Rate of liquid.

Measure the variable quantity of parameter.
Specifically, if detecting module 221 can be specifically used for probe when within the scope of no liquid container bottom preset height
It measures variable quantity and is greater than test judgement threshold value, then verify probe and take liquid success during once taking liquid
In one example, if detecting module 221 can also be used in probe apart from no liquid container bottom preset height range
