In this embodiment, the first measurement result compensation value and the second measurement result compensation value are determined according to the temperature compensation function and the humidity compensation function, and the scheme is simple and easy to implement.
Regarding electrochemical sensor measurements versus temperature: in a closed environment, the gas state inside can be considered to be stable. Data from 0 in the morning until 11 in the next morning. It can be seen that the measurement results are linear with the temperature trend, and continuously decrease. In fig. 4, the abscissa represents time, and the ordinate represents temperature and raw data of the electrochemical sensor, as shown in fig. 4, when the temperature reaches the lowest point, the measured value is at the lowest point and changes with the temperature, and when the temperature is in a certain interval and does not change, the measured result is maintained in a stable state.
To this end, in one embodiment, the temperature compensation function may be Cs1(t)＝k1*t+c1Wherein t represents a temperature value, Cs1(t) a temperature-dependent compensation value, k, representing the measurement of the electrochemical sensor1And c1Is a preset constant. In general, k1And c1Related to the sensitivity of the electrochemical sensor.
The measurement results versus temperature for different concentrations; the temperature value is changed, and the measurement result data of the electrochemical sensor under different gas concentrations are measured, so that the measurement results have common characteristics and are in a linear relation with the temperature. As shown in fig. 5, the abscissa is temperature and the ordinate is raw data at different gas concentrations.
Preferably, the temperature compensation function is C when concentration is considereds1(t,v)＝k2*t*v+c2Wherein t represents a temperature value, Cs1(t) a temperature-dependent compensation value, k, representing the measurement of the electrochemical sensor2And c2Is a preset constant.

I.e. substituting T ═ T, V ═ V into Cs1(t,v)＝k2*t*v+c2And obtaining a function value which is the compensation value of the first measurement result.
Regarding electrochemical sensor measurements versus humidity: when the electrochemical sensor is in a closed environment, the temperature of the closed environment is controlled and the environment humidity is adjusted through constant temperature control, and the original measurement data of the electrochemical sensor also changes correspondingly. The electrochemical sensor reactions are all in solution, and when the ambient humidity changes, the actual measurement result data is affected, as shown in fig. 6. By fitting the data in fig. 6, the mapping relationship between the humidity-related compensation value and the humidity value of the measurement result of the electrochemical sensor can be approximated as a quadratic function relationship.
To this end, in one embodiment, the humidity compensation function may be: cs2(h)＝a*h2+ b + h + C, where h represents the humidity value, Cs2(h) A humidity-dependent compensation value representing the measurement of the electrochemical sensor, a, b and c being predetermined constants, and the specific value may beSetting according to actual conditions. In general, a, b, and c are related to the sensitivity of the electrochemical sensor.
In one embodiment, the determining the second measurement result compensation value according to the humidity compensation function and the current humidity value may include: according to Cs2＝a*H2+ b × H + C determines the second measurement compensation value, Cs2Represents a second measurement result compensation value, H represents the current humidity value, and a, b, and c are preset constants. I.e. substituting H into Cs2(h)＝a*h2And + b + h + c, and obtaining a function value which is the compensation value of the second measurement result.
Measurement errors may occur in view of the multiple measurements taken by the sensor. The reasons for measurement errors are: instrument calibration, errors between sensors, gas flow rates, contaminant gases, etc. Are all accidental errors. Occasional errors are symmetrical and compensatory. That is, the positive and negative errors with equal absolute values have equal probability; under the same conditions, the arithmetic mean of the occasional errors tends to be 0 as the number increases, for the same quantity of repeated measurements.
According to the statistical theory, v (x) k x + f (x) is the measurement result, v is the actual measurement value, f (x) is the accidental error compensation value, and k is the preset constant. Wherein the content of the first and second substances,
to this end, in one embodiment, the determining the final measurement result of the electrochemical sensor according to the first measurement result compensation value, the second measurement result compensation value and the current actual measurement value may include:
according to P ═ Cs1+Cs2+ v (v) determining a final measurement of the electrochemical sensor, wherein v (v) k v + f (v),
Cs1representing the compensation value, C, of the first measurements2Represents a second measurement result compensation value, v represents the current actual measurement value, and σ represents a standardThe difference, pi, represents the circumferential ratio, k is a predetermined constant, and P represents the final measurement result.
Specifically, P (t, V, H) may be substituted with t-T, V-V and H-Hs1(t,v)+Cs2(h) + V (v), obtaining a function value as the final measurement result, wherein Cs1(t,v)＝k2*t*v+c2，Cs2(h)＝a*h2+b*h+c。
It should be understood that although the steps in the flowcharts of fig. 2 and 3 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
