Abstract

The invention discloses a calibration method and device for a code tooth sensor of a biochemical analyzer and a medium, and is applied to the technical field of biochemical analysis. According to the method, in the process that a reaction disc rotates to drive a target reaction container to pass through a light metering module, when a code tooth sensor corresponds to different positions of the target reaction container, the light metering module is controlled to conduct light metering so as to obtain a target brightness value after a reaction solution absorbs light. When the light source irradiates the middle position of the reaction container, the obtained target brightness value after the reaction solution absorbs light is higher than that of other positions, so that the target position corresponding to the maximum brightness value needs to be determined according to the target brightness values, and finally the position of the code tooth sensor is adjusted according to the target position. According to the scheme, the position offset of the code tooth sensor is detected and corrected, so that the position of the code tooth sensor is in an ideal state, and further data distortion and fluctuation of the biochemical analyzer are avoided.

Description

Technical Field

[0001] The present application relates to the technical field of biochemical analysis, and particularly to a calibration method, device and medium for a code tooth sensor of a biochemical analyzer. Background Art

[0002] A biochemical analyzer analyzes samples based on the absorbance of the samples. In actual applications, a sample and a reagent are configured into a reaction solution in a certain proportion and placed in a reaction container. After mixing and reacting, the absorbance of the reaction liquid is measured by the biochemical analyzer to analyze the sample. The photometric module of the biochemical analyzer includes an optical component and a signal processing module, which jointly form a photometric detection system. The optical component of the photometric module includes a light source and a light receiving part. A biochemical analyzer generally includes a reaction disk, which is usually a circular component, and a plurality of reaction containers are placed on the circumferential edge. The reaction disk performs a circular motion during testing, so that the reaction container passes through the photometric module. The light source irradiates light on the reaction container, which is then absorbed by the sample after biochemical color reaction, and the light receiving part receives the light passing through the reaction container to complete the sample analysis. In an actual analysis scenario, a biochemical analyzer generally uses a code tooth sensor to identify the reaction container number. After identifying the reaction container, photometry is started, and the photometric data is processed by an algorithm and corresponding to the reaction container.

[0003] However, in the design and installation process of the code tooth sensor of the biochemical analyzer, there is inevitably an error between its actual position and the ideal position.

[0037] In the calibration method of the code tooth sensor of the biochemical analyzer provided by the present application, during the process that the reaction disk rotates to drive the target reaction container to pass through the photometric module, when the code tooth sensor corresponds to different positions of the target reaction container respectively, the photometric module is controlled to perform photometry to obtain the target brightness value after the reaction solution absorbs light. Since when the photometric module performs photometry, it is most appropriate for the light source to irradiate the middle position of the reaction container, and the code tooth sensor needs to correspond to this position to perform photometry when the reaction disk rotates to the corresponding position. When the light source irradiates the middle position of the reaction container, the obtained target brightness value after the reaction solution absorbs light is higher than that of other positions.

[0047] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0048] The core of the present application is to provide a calibration method, device and medium for the code tooth sensor of a biochemical analyzer to solve the problem of data distortion and fluctuation caused by the non-ideal position of the code tooth sensor.

[0049] In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0050] Figure 1 Functional block diagram of a photometric module provided by an embodiment of the present application; as Figure 1As shown in the figure, the photometric module of the biochemical analyzer includes an optical component 1 and a signal processing module 2. The optical component 1 includes a light source and a light receiving part. Generally, a circular reaction disk is set, and multiple reaction vessels are placed on the periphery of the circle. The reaction disk rotates during the test to make the reaction vessels pass through the photometric module. The light source irradiates light on the reaction vessels, and then the light is absorbed by the sample after the biochemical color reaction. The light receiving part then receives the light passing through the reaction vessels, thus completing the sample analysis. The photometric detection schemes commonly used in biochemical analyzers are as follows: The light source irradiates light on the reaction vessels filled with reaction liquid, the light receiving part receives the light passing through the reaction vessels, and the signal processing module 2 converts the received light quantity into an electrical signal that can be collected and performs filtering and amplification processing (signal amplification), and then performs data processing after analog-to-digital (A / D) conversion. Finally, the light quantity passing through the reaction solution is reflected as absorbance data. Absorbance refers to the logarithm to the base 10 of the ratio of the incident light intensity before the light passes through the solution or substance (I0) to the transmitted light intensity after the light passes through the solution or substance (I1) (i.e., lg(I0 / I1)), where I0 is the incident light intensity and I1 is the transmitted light intensity. In this solution, the absorbance data can be defined as the logarithm to the base 10 of the ratio of the AD value (i.e., the value after analog-to-digital conversion) of the reaction vessel filled with pure water measured by the photometric module to the AD value of the reaction vessel filled with solution (A0 / A1) (i.e., lg(A0 / A1)), where A0 is the AD value of measuring pure water and A1 is the AD value of measuring the solution.

[0051] As mentioned above, improper position of the code tooth sensor will affect the determination of the photometric area and the processing of valid data, resulting in distorted and fluctuating finally obtained data. Therefore, the embodiment of the present application provides a calibration method for the code tooth sensor of a biochemical analyzer. In this solution, the position of the code tooth sensor is set to be adjustable and needs to be corrected according to the photometric data. Figure 2 It is a flowchart of a calibration method for the code tooth sensor of a biochemical analyzer provided by the embodiment of the present application; as Figure 2 shown, the method includes the following steps:

[0052] S10: During the process that the reaction disk rotates to drive the target reaction vessel to pass through the photometric module, when the code tooth sensor corresponds to different positions of the target reaction vessel respectively, control the photometric module to perform photometry to obtain the target brightness value after the reaction solution absorbs light.

[0053] S11: Determine the target position corresponding to the maximum brightness value according to each target brightness value.

[0054] S12: Adjust the position of the code tooth sensor according to the target position.

[0055] In actual application, the shape of the reaction disk, the movement mode, and the placement position of the reaction vessel are not limited. In this embodiment, the reaction disk is taken as a circular component. A plurality of reaction vessels are evenly placed on the circular edge of the reaction disk. When measuring light, the reaction disk makes a circular motion to drive each reaction vessel to pass through the light measuring module. When the reaction disk makes a circular motion, the left edge of the reaction vessel first passes through the light measuring module, and then horizontally moves into the light measuring module until the right edge moves out of the light measuring module. When moving from left to right, if the position of the code tooth sensor is different, it will cause the reaction vessel to trigger light measurement at different positions. The optimal position is when the light source irradiates the middle position of the reaction vessel. At this time, the target brightness value (AD value) of the reaction solution after light absorption received by the light receiving part is higher than that at other positions, and problems such as data distortion and fluctuation will not occur. Therefore, in the solution provided in this embodiment, when the code tooth sensor corresponds to different positions of the target reaction vessel, the light measuring module is controlled to measure light to obtain the target brightness value of the reaction solution after light absorption, then the maximum brightness value and the corresponding target position are determined, and finally the position of the code tooth sensor is adjusted to the target position so that the light source irradiates the middle position of the reaction vessel during light measurement. Here, adjusting the position of the code tooth sensor according to the target position can be to give an adjustment prompt, and then the debugger adjusts the code tooth sensor according to the prompt. Figure 3 It is a waveform schematic diagram of the light measurement data and the code disk signal when no reaction vessel is placed; as Figure 3 shown, the waveforms of the light measurement data and the code disk signal change according to a periodic law. Figure 4 It is a waveform schematic diagram of the light measurement data and the code disk signal when the position of the code tooth sensor is offset; as Figure 4 shown, when the position of the code tooth sensor is offset, the light measurement data is distorted. Figure 5 It is a waveform schematic diagram of the light measurement data and the code disk signal when the code tooth sensor is in an ideal position provided by the embodiment of the present application; as Figure 5 shown, after being adjusted by the solution of this embodiment, the code tooth sensor is in an ideal position, and at this time the light measurement data is not distorted.

[0056] When the light measurement signal processing unit of the biochemical analyzer collects dynamic light measurement data, it will also collect the code tooth sensor signal. The reaction disk makes a circular motion, and when the reaction vessel passes through the light measuring module, the absorbance data of the reaction vessel (which contains the information of the target brightness value) is measured. In actual application, it can be set that each high level of the code tooth signal corresponds to a light measurement area of a reaction vessel, the target brightness values at each position in the light measurement area can be obtained, then the data at each position in the light measurement area is calculated for the average value, the light measurement area corresponding to the largest average value is determined, and finally the middle position of the light measurement area is used as the target position.

[0057] In addition, after adjusting the position of the code tooth sensor according to the target position, if the code tooth sensor is still not in the ideal position, continue the above steps until the position of the code tooth sensor meets the preset requirements, that is, the target brightness value (AD value) absorbed by the reaction solution received by the light receiving part is higher than that at other positions at this time. The position of the code tooth sensor is judged whether it is offset through photometric data, and the offset amount of the code tooth sensor position is judged through a software algorithm. The debugger can simply and clearly adjust the sensor accordingly. This operation is generally completed in the production debugging link.

[0058] In practical applications, the light source irradiates light on the reaction vessel, which is then absorbed by the sample after biochemical color reaction. The light receiving part then receives the light passing through the reaction vessel and can be dispersed into 16 wavelengths by a spectrophotometer. The light of 16 wavelengths is converted into an electrical signal by a photodiode array, amplified by a preamplifier after voltage / current (V / I) conversion, and then after A / D acquisition, the central processing unit (CPU) performs algorithm processing and sends the effective AD value to a personal computer (PC). After that, it is calculated as absorbance data through a formula.

[0059] Generally, a halogen lamp is used as the light source for a biochemical analyzer, and it can be powered by a constant voltage source. The constant voltage source can output a fixed voltage using a switching regulated power supply, or be adjusted to a fixed voltage by a potentiometer during production debugging. However, this method cannot automatically adjust the power supply voltage of the halogen lamp. The halogen lamp works at a fixed voltage. When the biochemical analyzer does not perform tests for a long time, the halogen lamp can be turned off, but it takes a long time to enter the stable state when it is turned on again; or the halogen lamp can be kept at the working voltage all the time, but this solution consumes the service life of the halogen lamp. Therefore, this embodiment also provides a solution. If the biochemical analyzer has not performed photometry for a preset duration or the biochemical analyzer receives a standby instruction, the power supply voltage of the light source of the biochemical analyzer can be reduced, generally to 10V, to reduce the heat generation of the halogen lamp; if the biochemical analyzer starts photometry again, the power supply voltage of the light source is adjusted from the preset voltage value to the normal working voltage value of the light source. This solution not only ensures that the halogen lamp can quickly enter the state when the biochemical analyzer needs to perform tests, but also extends the service life of the halogen lamp.

[0060] The power supply of the halogen lamp uses a switching power supply chip to build a direct current - direct current (DC - DC) buck circuit. The buck circuit uses a digital potentiometer to feedback - regulate the output voltage. This digital potentiometer is connected to the single - chip microcomputer through a Serial Peripheral Interface (SPI) interface, and finally realizes the adjustment of the halogen lamp voltage through the client software or the control machine. In addition, due to the high power of the halogen lamp, when the power supply line of the halogen lamp is long, the voltage drop is relatively high, up to more than 1V, and the light intensity attenuation is serious. Then, the halogen lamp voltage can be increased for corresponding compensation, so as to improve the photometric performance and the service life of the halogen lamp.

[0061] In this embodiment, the software - adjustable supply voltage of the halogen lamp is realized through a digital potentiometer. When the instrument does not perform tests for a long time, the halogen lamp voltage is reduced to extend the service life of the halogen lamp. This solution also increases the voltage for corresponding compensation when the line attenuation is serious. In addition, the position offset detection of the code - tooth sensor is realized through a software algorithm, which is convenient for the debuggers to debug the equipment. Generally, the function of detecting the position offset of the code - tooth sensor is integrated in the client software. After execution, the position offset information of the code - tooth sensor is directly output, and the debuggers can make corresponding adjustments conveniently and quickly.

[0062] A calibration method for the code - tooth sensor of a biochemical analyzer provided by an embodiment of the present application. During the process that the reaction disk rotates to drive the target reaction container to pass through the photometric module, when the code - tooth sensor corresponds to different positions of the target reaction container, the photometric module is controlled to perform photometry to obtain the target brightness value after the reaction solution absorbs light. Because when the photometric module performs photometry, the most suitable position for the light source to irradiate on the reaction container is the middle position. The code - tooth sensor needs to correspond to this position to perform photometry when the reaction disk rotates to the corresponding position. When the light source irradiates on the middle position of the reaction container, the obtained target brightness value after the reaction solution absorbs light is higher than that of other positions. Therefore, it is necessary to determine the target position corresponding to the maximum brightness value according to each target brightness value, and finally adjust the position of the code - tooth sensor according to the target position. By detecting and correcting the position offset of the code - tooth sensor through this solution, the position of the code - tooth sensor is in an ideal state, thereby avoiding data distortion and fluctuation of the biochemical analyzer.

[0063] In the above embodiments, it is mentioned that the target reaction vessel may include multiple photometric regions. Generally, the photometric regions are adjacent to each other and may overlap. In the solution provided in this embodiment, during the rotation of the reaction disk to drive the target reaction vessel past the photometric module, when the code tooth sensor corresponds to different positions of the target reaction vessel, controlling the photometric module to perform photometry to obtain the target brightness value after the reaction solution absorbs light includes: obtaining the target brightness values at each position within the photometric region. Correspondingly, determining the target position corresponding to the maximum brightness value based on each target brightness value includes: determining the average brightness value of the target brightness values at each position within the photometric region; comparing the average brightness values corresponding to multiple photometric regions to determine the maximum average brightness value; and determining the middle position of the photometric region corresponding to the maximum average brightness value as the target position. Number the photometric AD value data obtained from each trigger position from left to right on the reaction vessel, and each numbering interval corresponds to a photometric region. For example, from data number a to data number b, a total of (b - a + 1) photometric AD value data are obtained, and then the average value n of the photometric AD value data is calculated. Then calculate the average value m1 of a total of (b - a + 1) photometric AD value data from data number (a - 1) to data number (b - 1). The average value m2 of a total of (b - a + 1) photometric AD value data from data number (a - 2) to data number (b - 2)...... Calculate the average value p1 of a total of (b - a + 1) photometric AD value data from data number (a + 1) to data number (b + 1), and calculate the average value p2 of a total of (b - a + 1) photometric AD value data from data number (a + 2) to data number (b + 2)...... Then the average brightness values corresponding to each adjacent photometric region of the target reaction vessel from left to right are...... m2, m1, n, p1, p2......; then calculate the maximum value among them. If the maximum value is n, the sensor is not offset and no adjustment is required; if the maximum value is m1, adjust the code tooth sensor 1 position to the left; if the maximum value is p1, adjust the code tooth sensor 1 position to the right......

[0064] After adjusting the position of the code tooth sensor according to the target position, it may not be adjusted to the ideal position, so further adjustment is needed. Therefore, this embodiment provides a solution. If the position of the code tooth sensor does not meet the preset requirements, that is, the target brightness value (AD value) of the reaction solution after light absorption received by the light receiving part at this time is not the highest compared with other positions, then return to the step of controlling the photometric module to perform photometry to obtain the target brightness value of the reaction solution after light absorption when the code tooth sensor corresponds to different positions of the target reaction vessel during the rotation of the reaction disc to drive the target reaction vessel past the photometric module, until the position of the code tooth sensor meets the preset requirements. In practical applications, the debugger can adjust the position of the code tooth sensor according to the detection result of the code tooth sensor, and execute the detection program again after adjustment. If the requirements are not met, the debugger is instructed to make adjustments again until the detection result shows that the position of the code tooth sensor is normal and no adjustment is required.

[0065] As mentioned in the above embodiment, in specific implementation, if the light source is powered by a constant voltage source, automatic adjustment of the power supply voltage of the light source cannot be achieved, which will cause inconvenience in using the light source. For example, if the biochemical analyzer does not perform tests for a long time and the light source is selected to be turned off, it takes a long time to enter the stable state when it is turned on again. And if the light source is always kept at the working voltage, the service life of the light source will be consumed. Therefore, this embodiment provides two solutions. Solution 1: If the biochemical analyzer has not performed photometry for a preset duration, adjust the supply voltage of the light source of the biochemical analyzer to a preset voltage value; wherein, the preset voltage value is lower than the normal working voltage value of the light source. Solution 2: If the biochemical analyzer receives a standby instruction, adjust the supply voltage of the light source to a preset voltage value. Correspondingly, after adjusting the supply voltage of the light source to the preset voltage value, it further includes: if the biochemical analyzer starts photometry again, adjust the supply voltage of the light source from the preset voltage value to the normal working voltage value of the light source. Through the solution provided in this embodiment, it not only ensures that the halogen lamp can quickly enter the state when the biochemical analyzer needs to perform tests, but also extends the service life of the halogen lamp.
