Please, it is not used to limit the application.
In order to improve the success rate and accuracy of sample-adding or sampling when being loaded or being sampled by detection device, this
Application embodiment provides the method, apparatus, equipment and medium of a kind of speed control.
The embodiment of the present application is mainly used in detection device, also can be applied to other setting comprising pipeline and syringe
Standby, this is not restricted.In the embodiment of the present application, only it is illustrated by taking detection device as an example.
As shown in fig.2, for a kind of structural schematic diagram of detection device in the embodiment of the present application mode.Detection is set in Fig. 2
Standby includes container 201, suction needle 202, pipeline 203, injection control apparatus 204 and sensor 205.
Injection control apparatus 204 is loaded into container 201 or is taken from container 201 by pipeline 203 and suction needle 202
Sample.
Wherein, sensor 205 is installed on the pipeline between suction needle 202 and injection control apparatus 204, and is commonly installed
In the position close to injection control apparatus 204, for acquiring the pipeline pressure of pipeline.Optionally, sensor can be hydraulic biography
Sensor.
In the embodiment of the present application, sensor is additionally mounted on detection device in conventional manner, to detect pipeline
Pipeline pressure, and then the speed control that sample-adding is realized by pipeline pressure and is sampled.
As shown in fig.3, being a kind of implementation flow chart of the method for speed control provided by the present application.Below based on Fig. 2
Shown in detection device, this method is specifically described, the specific implementation process of this method is as follows:
Step 300: detection device, which determines, receives plus samples instruction, and control syringe is according to setting plus sample rate progress
Add sampling, and according to setting plus sample rate, determines the initial transmission speed of sample delivery in pipeline.
Specifically, user when being detected by detection device, is if desired loaded or samples, then issue to detection device
For be loaded or sample plus sampling instruction.Detection device, which determines, to be received plus samples instruction, then is based on plus sampling instructs operation
Motor adds sampling according to setting plus sample rate by motor pushing syringe, and by setting plus sample rate, can determine
The initial transmission speed of sample delivery in pipeline.
Wherein, the transmission speed of sample can add sample rate to determine by syringe in pipeline, that is to say, that logical
That crosses control syringe adds sample rate, so that it may control the transmission speed of sample delivery in pipeline.
Wherein, add sampling instruction for the instruction for being loaded or sampling.It sets plus sample rate is pre- in motor as user
First configure.Initial transmission speed in pipeline refers to that sample flows through the speed being mounted in pipeline in sensor.It is usually initial
Transmission speed is minimum transmission rate.And minimum transmission rate is to be added to take according to the type of motor, the length of pipeline and sample
It is sample plus that sample time threshold value determines.
Step 301: detection device detects the initial tract pressure of pipeline by sensor, and obtains sample by densimeter
Sample rate.
Specifically, initial when detection device is detected in acquisition pipeline by sensor with initial transmission speed transmission sample
Pipeline pressure, and the sample rate by the ratio between the sample and pure water of densimeter acquisition equivalent, as sample.
Wherein, the transmission speed of sample and pipeline pressure have certain corresponding relationship in pipeline.
In this way, the current sample rate of sample can be obtained in real time by densimeter, the accuracy of sample rate is improved.
Step 302: sample rate of the detection device based on initial transmission speed, initial tract pressure and sample obtains
The first corresponding relationship between transmission speed and syringe resistance.
Specifically, detection device is based on initial transmission speed, initial tract pressure and sample rate, pipe resistance is determined
Coefficient, and according to pipe resistance coefficient, obtain the first corresponding relationship between transmission speed and syringe resistance.Pipe resistance system
Number is negatively correlated with initial transmission speed, initial tract pressure and sample rate.
Wherein, the principle that pipe resistance coefficient determines is as follows:
When determining pipe resistance coefficient, following formula can be used:
Wherein, as shown in fig.1, p1 is atmospheric pressure, p2 is pipeline pressure, v1For the pace of change of sample in container
(decrease speed or the rate of climb), v2For initial transmission speed, h1 is the liquid level of sample in container, and h2 is the height of sensor
Degree, ρ is sample rate, and g is acceleration of gravity, hfFor pipe resistance, λ is along road drag losses, and d is internal diameter of the pipeline, and ζ is part
Drag losses.
Since in practical application, container diameter is much larger than sensor internal diameter, v1It is negatively correlated with container diameter, v2With sensing
Device internal diameter is negatively correlated, therefore, v2Much larger than v1,It can be ignored.H2-h1 also can be neglected simultaneously.It is true in pipeline
Periodically,It is a constant with ζ.Above-mentioned two formula can simplify as following two formula as a result:
Wherein, p1 is atmospheric pressure, and p2 is pipeline pressure, v2For initial transmission speed, ρ is sample rate, and g adds for gravity
Speed, hfFor pipe resistance, C is pipe resistance coefficient.
In this way, after the initial transmission speed that will acquire, initial tract pressure and sample rate input above-mentioned two simplification
Formula, can determine pipe resistance coefficient.Thus, it is possible to obtain the third pair between pipe resistance and variant transmission speed
It should be related to are as follows:
Wherein, hfFor pipe resistance, C is pipe resistance coefficient, vxFor transmission speed, g is acceleration of gravity.
Refering to shown in Fig. 4 a, the schematic diagram of relationship between a kind of transmission speed and pipe resistance.By Fig. 4 a it is found that pipeline
Resistance is positively correlated with transmission speed.
Further, since syringe resistance is mainly to pass through pipe resistance and frictional force determination, and syringe exists
Inhaling the frictional force that is subject to during sample and sample-adding is all kinetic force of friction, and the constant magnitude of frictional force, therefore, transmission speed with
The first corresponding relationship between syringe resistance can be indicated using following formula:
Fs=hf+hc；
Wherein, Fs is syringe resistance, hfFor pipe resistance, hcFor frictional force.
Refering to shown in Fig. 4 b, the schematic diagram of relationship between a kind of syringe resistance and transmission speed.By Fig. 4 b it is found that note
Emitter resistance is positively correlated with transmission speed.
In this manner it is possible to obtain pipe resistance system by initial transmission speed, initial tract pressure and sample rate
Number, and then determine the first corresponding relationship between transmission speed and syringe resistance.
Step 303: detection device obtains the second corresponding relationship between transmission speed and syringe thrust, and is based on first
Corresponding relationship and the second corresponding relationship, determine maximum transfer speed.
Specifically, the second corresponding relationship between syringe thrust and transmission speed, can be obtained by supplier.Then examine
Measurement equipment directly acquires the second corresponding relationship, and is based on the first corresponding relationship and the second corresponding relationship, judges whether there is one
The corresponding syringe resistance of transmission speed syringe thrust corresponding with the transmission speed is identical；If so, by the transmission speed
It is determined as maximum transfer speed.
Wherein it is determined that when maximum transfer speed, it can be in the following ways:
Refering to the curve synoptic diagram shown in Fig. 4 c, determined for a kind of maximum transfer speed.By Fig. 4 c it is found that the first corresponding pass
It is corresponding resistance curve, the crosspoint A between thrust curve corresponding with the second corresponding relationship, i.e. the syringe resistance of A point
It is identical as syringe thrust, then the transmission speed of A point is determined directly as maximum transfer speed.
This is because syringe resistance is pushed away increasing in syringe when transmission speed is greater than the maximum transfer speed
Power can not continue to improve transmission speed.And when transmission speed is less than the maximum transfer speed, syringe thrust is greater than syringe
Therefore resistance can accelerate transmission speed.
Step 304: minimum transmission rate of the detection device based on maximum transfer speed and setting carries out transmission speed
Adjustment.
Specifically, minimum transmission rate and first pre-set velocity coefficient of the detection device based on setting, determine minimum fortune
Scanning frequency degree, and it is based on maximum transfer speed and the second pre-set velocity coefficient, determine maximum operational speed.Wherein, minimum transfer
Speed is refering to the corresponding transmission speed of B point in Fig. 4 c.
If maximum transfer speed is higher than the minimum speed of service, and transmission speed is not less than maximum operational speed, then detects
Equipment control transmission speed remains unchanged；
If maximum transfer speed is higher than the minimum speed of service, and transmission speed is lower than maximum operational speed, then detection is set
It is standby that transmission speed is accelerated according to preset acceleration, until transmission speed is not less than maximum operational speed, control transmission
Speed remains unchanged.
Wherein, the minimum speed of service is positively correlated with minimum transmission rate, and maximum operational speed is in maximum transfer speed
It is positively correlated.First pre-set velocity coefficient and the second predetermined coefficient can be set according to practical application scene, all can be appointed
Meaning positive number.Optionally, the first pre-set velocity coefficient can be 1.1, and the second pre-set velocity coefficient can be 0.9.
Theoretically, transmission speed can any one value between minimum transmission rate and maximum transfer speed, still,
In practical application, since transmission speed is too small, will lead to plus sampling efficiency it is too low, therefore, by the first pre-set velocity coefficient with
And minimum transmission rate, determine the preferably minimum speed of service.Initial transmission speed is typically equal to or greater than minimum transmission rate,
Acceleration can be configured according to practical application scene, and the value being usually arranged is smaller.Further, to avoid transmission speed mistake
Height obtains preferable maximum operational speed by the second pre-set velocity coefficient and maximum transfer speed.
Optionally, when determining the minimum speed of service, following formula can be used:
Vmin1=W1*Vmin2；
Wherein, Vmin1 is the minimum speed of service, and W1 is the first pre-set velocity coefficient, and Vmin2 is minimum transmission rate.
Optionally, when determining maximum operational speed, following formula can be used:
Vmax1=W2*Vmax2；
Wherein, Vmax1 is maximum operational speed, and W2 is the second pre-set velocity coefficient, and Vmax2 is maximum transfer speed.
Further, if maximum transfer speed is lower than the minimum speed of service, warning message is issued the user with.
This is because the liquid viscosity of sample is higher, resistance curve shown in Fig. 4 c then can be more precipitous, and then maximum transmitted
Speed can increasingly level off to minimum transmission rate.When maximum transfer speed is lower than the minimum speed of service, add sampling overtime,
It can be more than set plus sample time threshold value, and be likely to result in plus sample inaccurate or fail, for this purpose, if maximum transmitted
Speed is lower than the minimum speed of service, then detection device issues the user with warning message.
Optionally, due to the pipeline pressure in transmission speed and pipeline be with corresponding relationship, hence, it can be determined that
When Vmax2=Vmin1=W1*Vmin2, corresponding maximum pipeline pressure p max, then when sensor detects the pipeline pressure of pipeline
When power is higher than maximum pipeline pressure p max, alert.
In the embodiment of the present application, transmission speed is adjusted according to maximum transfer speed and minimum transmission rate, so that plus taking
Syringe thrust is not less than syringe resistance always during sample, improves the success rate and accuracy of sample-adding or sampling.
As shown in fig.5, the detailed implementation flow chart of a kind of method for speed control.The specific steps of this method are such as
Under:
Step 500: detection device, which determines, receives plus samples instruction, and control syringe is according to setting plus sample rate release
Sample, and according to setting plus sample rate, calculate the initial transmission speed that sample flows through the sensor installed in pipeline.
Step 501: detection device detects the initial tract pressure of pipeline by sensor.
Step 502: sample rate of the detection device based on initial transmission speed, initial tract pressure and sample obtains
