In implementation, the first environmental parameter detector 8 may be disposed on a housing of the air pollutant detecting apparatus, and configured to detect an external environment in real time, obtain detection data (i.e., first environmental parameter detection data) of one or more environmental parameters (e.g., a flow rate, a temperature, and a humidity of a gas), and send the detection data to the index computing device 7 in real time, where the index computing device 7 determines which environmental parameter or parameters need to be adjusted according to the detection data and a preset value range stored therein, and further calculates a value of an operating parameter (e.g., a heating power of the heater 5, and the like) of the environmental parameter adjusting device 1 required to adjust the corresponding environmental parameter, and sends the value to the environmental parameter adjusting device 1. For example, the external environment temperature is-5 ℃, the preset numerical range of the temperature is greater than 5 ℃, and the index calculation device 7 can determine the required heating power value according to the temperature difference between the external environment temperature and the preset numerical range, and control the heater 5 in the environmental parameter adjustment device 1 according to the heating power value.
Optionally, the index calculation device 7 is configured to obtain third detection data detected by the sensor device 2, and determine a concentration value of a preset pollutant in the gas collected by the air pollutant detection device according to the third detection data and a preset function.
The third detection data is detection data of an intermediate parameter used for calculating the concentration value, the intermediate parameter is a parameter that can be directly detected by the sensor device 2, and is the above-mentioned parameter that can indirectly reflect the concentration of a certain pollutant in the gas, for example, the intermediate parameter is a light transmission duty ratio, the sensor device 2 may include a laser and a light intensity sensor, the gas sample flows through between the laser and the light intensity sensor, and the laser emitted by the laser passes through the gas sample and irradiates on the light intensity sensor. For different concentrations of pollutants in the gas sample, the light intensity sensor can detect different light intensity values, a certain light intensity threshold value can be set, if the detected light intensity value is greater than the threshold value, the detected light intensity value is marked as 'empty', and if the detected light intensity value is less than the threshold value, the detected light intensity value is marked as 'occupied', and then the light transmission duty ratio can be calculated.
In an implementation, the sensor device 2 may detect the value of the transmittance duty ratio (i.e., the third detection data) in real time and send the value to the index calculation device 7, and the index calculation device 7 may store a functional expression in advance, where the functional expression is a formula for converting the detection data of the intermediate parameter into a concentration value of a preset pollutant, and based on the functional expression, the index calculation device 7 may convert the received third detection data into a corresponding concentration value, such as a concentration value of PM 2.5.
Optionally, in some cases, the environment is too harsh, and the environmental parameter adjusting device 1 may not adjust the parameter value of the environmental parameter to the preset value range, and at this time, may perform certain adjustment on the function expression to ensure the accuracy of the final concentration value, and accordingly, as shown in fig. 8, the following structure and function may be set in the air pollutant detecting apparatus:

In practice, the second environment parameter detector 9 may detect the environment parameter of the gas processed by the environment parameter adjusting device 1, and send the environment parameter detection data (i.e., the second environment parameter detection data) to the index calculating device 7. The index calculation means 7 determines whether the second environment parameter detection data is within a preset value range, and if so, may process the third detection data of the sensor device 2 based on the above functional formula to obtain a corresponding concentration value, otherwise, may process the third detection data of the sensor device 2 based on the adjustment functional formula to obtain a corresponding concentration value. The index calculation means 7 may store a correspondence between the environmental parameter detection data and the adjustment function expression, and may search the corresponding adjustment function expression for calculating the concentration value by searching the correspondence using the second environmental parameter detection data. In the corresponding relationship, different adjustment function expressions corresponding to different value intervals of the environmental parameter detection data may be recorded.
For example, if the temperature value range in the preset value range is interval a1, the humidity value range is interval B1, and the flow rate value range is interval C1, and the temperature value in the second environmental parameter detection data is lower than the lower limit of interval a1, i.e., exceeds the range of interval a1, the interval to which the temperature value belongs is interval a2, and the humidity value and the flow rate value in the second environmental parameter detection data do not exceed interval B1 and interval C1, respectively, then the adjustment function expressions corresponding to interval a2, interval B1, and interval C1 may be queried in the above correspondence relationship for calculating the concentration value.
As shown in fig. 9, a compensation module 12 may be disposed in the air pollutant detecting apparatus for completing the above-mentioned processing of obtaining the adjustment function, and the compensation module 12 may store a corresponding policy of obtaining the adjustment function, that is, a corresponding relationship between the environmental parameter detection data and the adjustment function.
