Figure 10 is the flow chart of TDS detection methods according to a fourth embodiment of the present invention, as shown in Figure 10, the method according to
Environment temperature, two big intervals are divided into by temperature, and detection water temperature disease is got after water quality sampling value, and advanced trip temperature is sentenced
Disconnected, when temperature is relatively low, temperature in use penalty method carries out the calculating of water quality TDS values, is carried out using near comparison method when temperature is higher
The calculating of water quality TDS values, with it, the precision and stability of the TDS values detection that can increase water quality.
It will be seen from figure 1 that there is no the AD values for overlapping (except TDS is 0 between corresponding each curve of the difference temperature
Situation), wherein, in the case where water temperature is less than 20 DEG C, the AD values difference that identical TDS values are sampled in different temperatures
Than larger, therefore temperature in use penalty method carries out the calculating of water quality TDS values；In the case where water temperature is more than 20 DEG C, phase
With TDS value different temperatures when the AD values that sample differ smaller, therefore carry out water quality TDS values using close comparison method
Calculate.
Wherein, the flow chart of temperature compensation act is as shown in figure 11, by water temperature TWaterFor less than 20 DEG C of temperature are divided into Liang Ge areas
Between calculated, two different temperature points are designated as T1, T2（T1, T2 belong to natural number）, wherein T1<T2<20 DEG C, wherein T2
20 DEG C of infinite approach, if current water temperature is less than T1, after carrying out temperature-compensating, is calculated final on the basis of 1 DEG C of curve
TDS values；If current water temperature is less than T2 but during more than or equal to T1, calculated on the basis of 10 DEG C of curve after temperature-compensating
Go out final TDS values.
Temperature compensation act specifically performs flow：Work as water temperature TWater<During T1, A=is calculated（TWater-1）%2, enters to water quality sampling value
Row amendment, TDS_ADAfter amendment=TDS_ADBefore amendment+ A, then calculates final TDS values on the basis of 1 DEG C of curve；Work as water temperature
T1=<TWater<During=T2, B=(T are calculatedWater- 10) %2, is modified, TDS_AD to water quality sampling valueAfter amendment=TDS_ADBefore amendment+ B, then
Final TDS values are calculated on the basis of 10 DEG C of curve.
Specifically, when temperature is less than T1, temperature often raises 2 DEG C, Jia 1 on the basis of the AD values for detecting, such as
Assuming that temperature is 3 DEG C, AD values Jia 1, and temperature is 5 DEG C, and AD values Jia 2, and temperature is 7 DEG C, and AD values Jia 3, and temperature is 9 DEG C, and AD values Jia 4,
The rest may be inferred；In temperature less than T2 DEG C but during more than or equal to T1 DEG C, temperature often raises 2 DEG C just on the basis of the AD values for detecting
Plus 1, such as assume that temperature is 12 DEG C, AD values Jia 1, and temperature is 14 DEG C, and AD values Jia 2, and temperature is 16 DEG C, and AD values Jia 3, and temperature is 18
DEG C, AD values Jia 4, and the rest may be inferred.
Wherein, TDS_ADAfter amendmentIt is revised water quality sampling value, TDS_ADBefore amendmentIt is the water quality sampling value for getting, TWaterFor
The temperature of tested water, △ T are predesigned compensation temperature.
For example, if the temperature AD for detecting is 9, water quality AD is 185.Look into upper table 1 and understand present water temperature for 7 DEG C, therefore
The AD values of water quality need Jia 3 to be changed into 188, and then the data with 1 DEG C are compared, and draw final TDS values.
Wherein, the flow chart near comparison method is as shown in figure 12, when water temperature is more than 20 DEG C, is compared with being close to
Method is calculated, and mainly by C.T value, then looks for hithermost known temperature point to draw TDS values.Preset four temperature
Degree is interval：20 DEG C ~ T001, T001 ~ T002, T002 ~ T003, T003 ~ T004, and T01, T02, T03, T04 are respectively provided with
It is the fiducial temperature in each temperature range（20℃=<T01<T001<T02<T002<T03<T003<T04）, the T01 that now measures,
Sampled value-TDS value curves under T02, T03, T04.
Specifically performing flow near comparison method is：When 20 DEG C<=TWater<During=T001, the curve according to T01 obtains water quality TDS
Value, works as T001<TWater<During=T002, the curve according to T02 obtains water quality TDS values, works as T002<TWater<During=T003, according to the song of T03
Line obtains water quality TDS values, works as T003<TWater<During=T004, the curve according to T04 obtains water quality TDS values.
