Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The main solutions of the embodiments of the present invention are: after a plurality of reaction cups are subjected to photometry operation, a dynamic optical signal curve is obtained; based on the dynamic optical signal curve, acquiring the position information of a dynamic optical signal center point by using a positioning algorithm; the digital signal value corresponding to the dynamic optical signal center point is obtained by utilizing the position information of the dynamic optical signal center point, so that the technical problem that the centremost position of each reaction cup dynamic optical signal cannot be accurately positioned is solved, and the positioning precision and the measuring accuracy of the dynamic optical signal center point are improved.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
Referring to fig. 2, fig. 2 is a first embodiment of the dynamic optical signal processing method of the present application, the method comprising the steps of:
step S110: after a plurality of reaction cups are subjected to photometry operation, a dynamic optical signal curve is obtained;
The full-automatic biochemical analyzer is a common in-vitro diagnosis analyzer, the spectrophotometer is the most important signal detection system, the measuring light source irradiates the reaction cup and then is received by the detector, the photoelectric conversion processing is carried out on the light signal, the light signal is converted into a digital signal value, the absorbance of the measured substance can be obtained through calculating the digital signal value, and finally the concentration or activity of the measured substance can be calculated according to the calibration or calibration coefficient of the instrument.
The acquisition of the spectrophotometer optical signal is directly related to the accuracy of the measurement result. On a full-automatic biochemical analyzer, the transmitted light signal of the substance to be detected is obtained during the movement of the reaction cup. As shown in fig. 3, 101 is a light source of a spectrophotometer, 102 is a reaction cup and is uniformly arranged on a reaction disk, and 103 is a photodetector of a spectrophotometer. When the instrument is in operation, the reaction disk rotates around the rotation shaft 104 in a clockwise or counterclockwise direction, the position of the light spot irradiated on the reaction cups changes along with the rotation of the reaction disk, and each reaction cup sequentially passes through the spectrophotometer to be measured.
The biochemical analyzer measures the content or activity of the detected substance based on lambert beer law, and the absorbance calculating method comprises the following steps ofWherein I 0 and I 1 respectively represent the optical signals measured when the light source passes through the reaction cup at a certain moment, and both are obtained from dynamic optical signal curves. In theory, in the case of uniform rotation of the reaction disk, the center of the reaction cup corresponds to the middle position of the flat region of the optical dynamic curve, so that accurate positioning of the middle position of the dynamic optical signal is extremely important.
As shown in fig. 4, 201 and 202 represent the walls of the cuvette, 203 represent the measurement spot, and 204 represent the dynamic optical signal generated after the spot has been irradiated onto the cuvette. Because the middle portion of the cuvette has high light transmittance and the wall has low light transmittance, when the cuvette 102 rotates past the spectrophotometer, a dynamic optical signal is generated whose intensity varies with the position of the cuvette, wherein the rising and falling edges of the signal correspond to the variations when the wall passes the light spot 203, and the flat area of the middle portion of the signal corresponds to the variations when the light spot is fully illuminated at the middle transparent position of the cuvette.
FIG. 1 further illustrates the signal generation process, assuming that the reaction disk rotates counterclockwise, the right cup wall 301 of the reaction cup will be first illuminated by the light spot 303, and the optical signal will be changed from small to large, corresponding to the a-b segment of the dynamic optical signal; when the reaction cup continues to rotate, the light spot irradiates the middle light transmission area of the reaction cup completely, the optical signal value is larger and is a section of relatively stable optical signal, such as section b-c of a curve, the width of the flat area is related to the size of the light transmission area of the reaction cup and the size of the light spot, and in the actual measurement process, the optical signal slightly fluctuates due to the uniformity of the material of the reaction cup, the density distribution of the measured solution or other interference; as the cuvette continues to rotate, the left side wall 302 of the cuvette passes through the spot, where the optical signal is changed from large to small, corresponding to the c-d segment of the dynamic optical signal. Wherein connecting the a-b, b-c, and c-d segments generates a dynamic optical signal curve.
The digital signal value may be AD (Analog to Digital), and both the values are the same.
Step S120: and based on the dynamic optical signal curve, acquiring the position information of the center point of the dynamic optical signal by using a positioning algorithm.
Specifically, in this embodiment, the oscilloscope is not used for measurement and calibration, but a positioning algorithm is used to obtain the position information of the center point of the dynamic optical signal, and the center point of the dynamic optical signal of each reaction cup can be positioned in real time through numerical calculation, so that the positioning accuracy is greatly improved compared with the method of adjusting by using the oscilloscope.
Step S130: and obtaining a digital signal value corresponding to the dynamic optical signal center point by utilizing the position information of the dynamic optical signal center point.
In particular, in this embodiment, the digital signal value corresponding to the dynamic optical signal center point may be obtained using a dynamic optical signal curve, where the dynamic optical signal curve may be a functional representation of the dynamic optical signal position information and its corresponding digital signal value.
In an embodiment, obtaining a digital signal value corresponding to a dynamic optical signal center point by using position information of the dynamic optical signal center point includes:
Substituting the abscissa value of the dynamic optical signal center point into the dynamic optical signal curve to obtain a digital signal value corresponding to the dynamic optical signal center point.
In the above embodiment, the following beneficial effects exist: after a plurality of reaction cups are subjected to photometry operation, a dynamic optical signal curve is obtained; the dynamic optical signal curve is accurately obtained, so that the position of the center point of the dynamic optical signal is accurately obtained.
Based on the dynamic optical signal curve, acquiring the position information of a dynamic optical signal center point by using a positioning algorithm; and obtaining a digital signal value corresponding to the dynamic optical signal center point by utilizing the position information of the dynamic optical signal center point. The dynamic optical signal curve of each reaction cup is obtained, and the position information of the dynamic optical signal center point is accurately obtained by using a positioning algorithm, so that the accuracy of the digital signal value corresponding to the dynamic optical signal center point is ensured. The technical problem that the centremost position of the dynamic optical signal of each reaction cup cannot be accurately positioned is solved, and the positioning accuracy and the measuring accuracy of the center point of the dynamic optical signal are improved.
Referring to fig. 5, fig. 5 is a second embodiment of the dynamic optical signal processing method according to the present application, the method includes:
step S210: after a plurality of reaction cups are subjected to photometry operation, a dynamic optical signal curve is obtained;
Specifically, the dynamic optical signal of the reaction cup is obtained, the curve is shown in FIG. 6, and the function of the curve is set as
yn＝fn(x) (1)
Wherein n represents the nth reaction cup, x represents the serial number of the sampling point, and y represents the digital signal value.
Step S220: and acquiring the maximum value and the minimum value of the dynamic optical signal based on the dynamic optical signal curve.
Specifically, according to the dynamic optical signal curve, the maximum value and the minimum value of the dynamic optical signal may be directly obtained or obtained by using a mathematical method such as derivative, and the present embodiment is not limited to the above method, and may be obtained by other methods.
Step S230: and obtaining the calibration line by using the maximum value and the minimum value of the dynamic optical signal.
Specifically, the calibration line is obtained by using the maximum value and the minimum value of the dynamic optical signal obtained by the dynamic optical signal curve. Wherein the calibration line is a straight line with the horizontal direction parallel to the X axis.
In an embodiment, the obtaining the calibration line using the maximum value and the minimum value of the dynamic optical signal includes:
Step S231: calculating to obtain the sum of the maximum value and the minimum value of the dynamic optical signals;
Step S232: multiplying a preset constant by the sum to be used as an ordinate value of the calibration line. Specifically, the ordinate value of the calibration line is determined by the following formula:
An＝β×(y(n,max)+y(n,min)) (2)
Wherein y (n,max),y(n,min) represents the maximum value and the minimum value of the dynamic optical signal of the nth reaction cup, β is constant and 0< β <1, and β=0.5 is usually taken.
It should be noted that a preset constant is not limited to 0.5, and may be adjusted and set according to the specific environment of the experiment.
Step S240: and obtaining the intersection point position information of the calibration line and the dynamic optical signal curve.
In an embodiment, the obtaining the intersection point position information of the calibration line and the dynamic optical signal curve includes:
step S241: and on the basis of the longitudinal coordinate values, making a horizontal calibration line.
Step S242: and obtaining coordinate values of two intersection points of the calibration line and the dynamic optical signal curve.
Specifically, the intersection point of the calibration line y n＝An and the dynamic optical signal curve is calculated, and the coordinates of the two intersection points are obtained as (x (n,1),An)、(x(n,2),An) respectively.
Specifically, as shown in fig. 6, when a preset constant is 0.5, the horizontal line between the maximum value and the minimum value in fig. 6 is the calibration line, and two intersection points of the calibration line and the dynamic optical signal curve are (x 1,y0) and (x 2,y0), respectively.
Step S250: and obtaining the position information of the dynamic optical signal center point based on the intersection point position information.
In an embodiment, the obtaining the position information of the dynamic optical signal center point based on the intersection position information includes:
Step S251: and calculating and obtaining an average value of two intersection abscissa coordinates based on the two intersection coordinate values, and executing rounding operation on the average value.
In one embodiment, the rounding operation is performed using a rounding function.
In particular, the rounding function may be a round function, wherein the round function returns a value that is the result of a rounding operation according to a specified decimal place. In addition, in the present embodiment, the rounding function is not limited to the above, but may be a ceil function, a floor function, or the like, wherein the ceil function returns a value that is an integer that rounds up and is closest; and the floor function returns a value that rounds down to the nearest integer.
Step S252: and taking the integer result obtained after the rounding operation as the abscissa value of the dynamic optical signal center point.
Specifically, calculating the central values of the two intersection points and rounding to obtain the abscissa of the central point:
x(n,3)＝round[(x(n,1)+x(n,2))/2] (3)
Wherein round represents a rounding function, x (n,3) is the center point of the dynamic optical signal curve, and the position x (n,3) of the center point of the nth reaction cup is stored in the computer.
Step S260: and obtaining a digital signal value corresponding to the dynamic optical signal center point by utilizing the position information of the dynamic optical signal center point.
Specifically, digital signal values of the dynamic optical signals are sequentially acquired: and obtaining a value f n(x(n,3) corresponding to the dynamic optical signal curve by using the obtained central point position x (n,3)), namely the digital signal value of the current photometry of the nth reaction cup.
In the above embodiment, the following beneficial effects exist: after the dynamic optical signal curve of each reaction cup is obtained, the center point of the curve is independently determined through a positioning algorithm, so that the deviation of dynamic optical signals caused by mechanical positioning errors and uneven rotating speed of a reaction disk in multiple measurement is eliminated, and compared with a method for adjusting and calibrating the center point of each reaction cup by using an oscilloscope, the accuracy of positioning the center point of the dynamic optical signal is improved; meanwhile, the AD value of the center of the reaction cup is prepared more due to the fact that the positioning accuracy of the center point of the dynamic optical signal is improved, and therefore the accuracy of a measuring result is improved.
In a specific embodiment, fig. 7 is a diagram showing that 160 times of dynamic collection are performed on the same reaction cup, a conventional oscilloscope method is used to determine a center point, then a digital signal value is taken out, and a real-time dynamic curve center point determination scheme provided by the invention is used to obtain a digital signal value, and the change trends of the two digital signal values are plotted in fig. 8, wherein a solid line is the method of the embodiment, a dotted line is a conventional method, and the change trends of the two curves are basically the same as that of fig. 8, but the conventional oscilloscope method for locating the center point can cause jump of the digital signal value, which is mainly caused by errors in rotating speed or mechanical positioning of the reaction cup during multiple photometry, so that deviation occurs when the fixed center point is adopted for taking the value. The difference between the two curves is shown in fig. 9, and it can be seen that the value of the hopped digital signal is in the magnitude of hundreds to hundreds of dry degrees, which affects the accuracy of measurement, and the hopping error can be eliminated by adopting the method proposed by the embodiment.
