[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] The core of this application is to provide a blood analyzer calibration system and its control method, device, and medium to ensure the accuracy of the reference voltage of the blood analyzer, thereby improving the accuracy of the blood analysis process.

[0045] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0046] Figure 1 A structural diagram of a blood analyzer calibration system provided in an embodiment of the present application, such as Figure 1 As shown, the blood analyzer calibration system provided by the present application includes:

[0047] Controller 1, current detection device 2 and standard resistance strip 3;

[0048] The controller 1 is connected to the current detection device 2 to obtain a current detection signal; wherein the current detection signal is a current signal generated by the blood analyzer after the standard resistor strip 3 is inserted into the test paper socket of the blood analyzer;

[0049] The controller 1 is also connected to the reference power supply 4 of the blood analyzer to adjust the output voltage of the reference power supply 4 when the current detection signal does not meet the preset conditions; wherein the standard voltage signal is a signal corresponding to the standard resistance strip 3.

[0050] It should be noted that, since the current generated by the blood analyzer during operation is relatively weak, the voltage value output by the reference power supply 4 is also relatively low, so even a slight fluctuation of the reference power supply 4 may affect the normal operation of the blood analyzer. In order to improve the accuracy of the output voltage of the reference power supply 4, a digital-to-analog conversion module can be used to power the blood analyzer.

[0051] like Figure 1 As shown, the reference power supply 4 includes a voltage source and a digital-to-analog conversion unit; the digital-to-analog conversion unit is connected to the voltage source to obtain a reference voltage. The output end of the reference power supply 4 is connected to the in-phase input end of the operational amplifier of the blood analyzer; the input end of the current detection unit is connected to the output end of the operational amplifier; the inverting input end of the operational amplifier is connected to the first end of the test paper socket, and the second end of the test paper socket is grounded. The first end of the resistor R and the first end of the capacitor C are both connected to the first end of the test paper socket, and the second end of the resistor R and the second end of the capacitor C are connected to the output end of the operational amplifier.

[0052] In the specific implementation, firstly, the standard resistance strip 3 is inserted into the test strip socket of the blood analyzer. The system controls the reference power supply 4 to output the bias voltage V B , after passing through the amplifier, the output voltage value is V out Then the current detection device 2 collects the output voltage value and calculates the current value I through the system S , and then calculate the current value I S The difference between the standard current value Istandard is used to adjust the output bias voltage V of the reference power supply 4 B , thus ensuring that the collected current value I S When the current value is consistent with the standard value, the voltage calibration is completed.

[0053] The system controls the DAC module to output the reference voltage V B , assuming the resistance of standard resistor strip 3 is R 标准 , ideally:

[0054] V B =I S *R 标准 ;

[0055] V out =VB (R 标准 +R S ) / R 标准 =V B +I S *R S ;

[0056] ΔV out =V out标准 -V out测 ;

[0057] Among them, V out标准 is the standard voltage value, V out测 is the actual voltage value, ΔV out is the difference between the standard voltage value and the actual voltage value, R S is the resistance value of resistor R, I S is the current value flowing through the resistor. From the above formula, we can see that V B With V out It is a direct proportional relationship, which can be calculated based on ΔV out The positive and negative size of V B , so that it continues to approach the standard voltage value.

[0058] The present application provides a blood analyzer calibration system, including: a controller, a current detection device and a standard resistor strip; the controller is connected to the current detection device to obtain a current detection signal; wherein the current detection signal is a current signal generated by the blood analyzer after the standard resistor strip is inserted into the test strip socket of the blood analyzer; the controller is also connected to the reference power supply of the blood analyzer to adjust the output voltage of the reference power supply when the current detection signal does not meet the preset conditions; wherein the standard voltage signal is a signal corresponding to the standard resistor strip. It can be seen that the technical solution provided by the present application obtains the current detection signal when the standard resistor strip is inserted into the blood analyzer through the current detection device, and adjusts the output voltage of the reference power supply according to the standard voltage value and the current detection signal to achieve the calibration of the blood analyzer. There is no need to use large-scale tooling equipment, thereby reducing the calibration cost of the blood analyzer on the basis of ensuring the accuracy of the blood analysis process and improving the user experience.

[0059] Figure 2 A flow chart of a blood analyzer calibration system control method provided in an embodiment of the present application is as follows: Figure 2 As shown, the blood analyzer calibration system control method provided in this application includes:

[0060] S10: Acquire a current detection signal sent by the current detection device, wherein the current detection signal is a current signal generated by the blood analyzer after a standard resistor strip is inserted into a test paper socket of the blood analyzer;

[0061] S11: judging whether the current detection signal meets a preset condition according to the standard voltage signal;

[0062] S12: If the current detection signal does not meet the preset conditions, adjust the output voltage of the reference power supply; wherein the standard voltage signal is a signal corresponding to the standard resistance strip.

[0063] During the calibration process, first insert the standard resistor strip into the test strip socket of the blood analyzer, and obtain the current signal generated by the blood analyzer through the current detection device to generate a current detection signal. And obtain the voltage detection signal according to the current detection signal and the internal circuit parameter value of the blood analyzer, calculate the difference between the voltage detection signal and the standard voltage signal, and adjust the reference voltage output by the reference power supply according to the difference between the two.

[0064] In a specific implementation, when ΔV out = 0 (or within the error range (for example: ±0.5mV), not limited here), V out is the standard value, no calibration is required; when ΔV out <0, V out Greater than the standard value, the reference voltage V B Too large, ΔV out With V B Add, adjust V B The value of V B Decrease; when ΔV out >0, V out Less than the standard value, V B If ΔV is too small, out With V B Add, adjust V B The value of V B Increase.

[0065] It is understandable that the reference voltage may be gradually increased or decreased according to a preset step size, or the reference voltage may be adjusted using a binary method, which is not limited here.

[0066] The present application provides a blood analyzer calibration system control method, which is applied to a blood analyzer calibration system including a controller, a current detection device and a standard resistor strip. The controller is connected to the current detection device to obtain a current detection signal; the current detection signal is a current signal generated by the blood analyzer after the standard resistor strip is inserted into the test strip socket of the blood analyzer; the controller is also connected to the reference power supply of the blood analyzer to adjust the output voltage of the reference power supply when the current detection signal does not meet the preset conditions; the standard voltage signal is a signal corresponding to the standard resistor strip. It can be seen that the technical solution provided by the present application obtains the current detection signal when the standard resistor strip is inserted into the blood analyzer through the current detection device, and adjusts the output voltage of the reference power supply according to the standard voltage value and the current detection signal to realize the calibration of the blood analyzer. There is no need to use large-scale tooling equipment, thereby reducing the calibration cost of the blood analyzer on the basis of ensuring the accuracy of the blood analysis process and improving the user experience.

[0067] like Figure 2 As shown, judging whether the current detection signal meets the preset condition according to the standard voltage signal includes:

[0068] determining a voltage detection signal according to the current detection signal;

[0069] Determine whether the difference between the voltage detection signal and the standard voltage signal is greater than a voltage threshold;

[0070] If it is greater than the voltage threshold, it is determined that the current detection signal does not meet the preset condition.

[0071] As a preferred embodiment, adjusting the output voltage of the reference power supply includes: obtaining the voltage difference between the voltage detection signal and the standard voltage signal; and adjusting the output voltage by using a binary method according to the voltage difference. In a specific implementation, the specific adjustment method can use a binary method to adjust the bias voltage V output by the DAC. B .

[0072] V B2 =V B1 +1 / 2(R 标准 / (R 标准 +R S ))*ΔV out ;

[0073] Among them, V B1 is the initial bias voltage value, V B2 According to V B1 The calculated reference voltage value after the first adjustment, R 标准 is the resistance value of a standard resistor bar.

[0074] If ΔV out≠0, when adjusting the circuit, first adjust ΔV out Divide by the magnification factor R 标准 / (R 标准 +R S ) is divided into two, and then the bias voltage V B The advantage of binary adjustment is that it makes the result gradually approach the standard value and makes adaptive adjustments to the unstable hardware environment.

[0075] For example, when the reference voltage V B标准 =400mV, R 标准 =100kΩ, R S =300kΩ, the amplification factor

[0076] R 标准 / (R 标准 +R S )=4;

[0077] V out标准 =V B标准 (R 标准 +R S ) / R 标准 =4V B标准 =1600mV;

[0078] When V B1 =399mV, V out测 =4V B1 =1596mV;

[0079] At this time, ΔV out =V out标准 -V out测 =1600mV-1596mV=4mV;

[0080] After making the first adjustment to the circuit:

[0081] V B2 =V B1 +1 / 2(R 标准 / (R 标准 +R S ))*ΔV out =399mV+4*1 / 2*1 / 4=399.5mV;

[0082] Then make a second adjustment to the circuit: V out测 =4V B2 =1598mV;

[0083] ΔV out =V out标准 -V out测 =1600mV-1598mV=2mV;

[0084] Then, after the second adjustment of the circuit:

[0085] V B3 =V B2 +1 / 2(R 标准 / (R 标准 +R S ))*ΔV out =399.5mV+2*1 / 2*1 / 4=399.75mV;

[0086] V out测 =4V B3 =1599mV;

[0087] ΔV out =V out标准 -V out测 =1600mV-1599mV=1mV;

[0088] Among them, V B3 is the reference voltage value after the second adjustment.

[0089] In this way, after the third adjustment of the circuit:

[0090] V B4 =V B3 +1 / 2(R 标准 / (R 标准 +R S ))*ΔV out =399.75mV+1*1 / 2*1 / 4=399.875mV;

[0091] Among them, V B4 is the reference voltage value after the second adjustment.

[0092] Repeat the above steps until ΔV out If it is 0 or meets the allowable error range, it indicates that the calibration task has been completed.

[0093] As a preferred embodiment, after completing the reference voltage adjustment task, in order to facilitate maintenance personnel to understand the working status of the blood analyzer, the technical solution provided by the present application also includes: writing the adjustment data of the reference power supply into a log file for subsequent processing. Furthermore, the log file can be saved locally, or the corresponding log file can be uploaded to the cloud through an APP connected to the blood analyzer to improve the user experience.
