Description
本發明係一種校正方法,尤指一種濕度傳感器的校正方法。The invention is a calibration method, in particular a method for correcting a humidity sensor.
現有技術的電容式聚合物濕度傳感器是利用該電容式聚合物濕度傳感器的電容值會隨環境濕度值變化的特性,透過檢測該電容式聚合物濕度傳感器的電容值,進而推算出目前的環境濕度。The prior art capacitive polymer humidity sensor utilizes the characteristic that the capacitance value of the capacitive polymer humidity sensor changes according to the environmental humidity value, and the capacitance value of the capacitive polymer humidity sensor is detected to calculate the current environmental humidity. .
但因為製程能力,無法將每個濕度傳感器製作的一模一樣,因此每個濕度傳感器的反應結果都有些微的不同,也就是所謂的規格公差或變異範圍。舉例來說,該濕度傳感器的規格公差為100pF或該濕度傳感器的變異範圍為30%。However, because of the process capability, each humidity sensor cannot be made exactly the same, so the response result of each humidity sensor is slightly different, which is the so-called specification tolerance or variation range. For example, the humidity sensor has a specification tolerance of 100 pF or the humidity sensor has a variation range of 30%.
因此該濕度傳感器在使用時,需要經過一個校正方法來提高感測結果的準確度。由於校正方法的優劣決定了濕度傳感器的感測結果的準確度,且越高精度的校正方法需要越多的校正點,而越多的校正點就需要越多的時間成本與人力成本進行校正方法,因此,高精度的校正方法就需要足夠多的校正點來支持。Therefore, when the humidity sensor is used, a correction method needs to be performed to improve the accuracy of the sensing result. Because the accuracy of the calibration method determines the accuracy of the sensing result of the humidity sensor, and the more accurate the correction method requires more correction points, the more correction points require more time cost and labor cost to correct the method. Therefore, a high-precision correction method requires enough correction points to support.
當一批相同規格的濕度傳感器製作完成時,對於每個濕度傳感器而言,都具有不同的規格公差或變異範圍,因此在校正時,必須針對每一個濕度傳感器分別取多個校正點來進行校正,造成時間成本與人力成本的過度消耗,因而壓縮了廠商的利潤或造成商品價格的提高而降低競爭力。故對於現有技術的電容式聚合物濕度傳感器的校正方法而言,有必要做進一步之改良。When a batch of humidity sensors of the same specification is completed, each humidity sensor has different specification tolerances or variation ranges. Therefore, when calibration, multiple calibration points must be taken for each humidity sensor to be corrected. , resulting in excessive consumption of time and labor costs, thus reducing the profit of the manufacturers or causing the price of goods to increase and reduce competitiveness. Therefore, it is necessary to further improve the correction method of the prior art capacitive polymer humidity sensor.
有鑑於現有的高精度的電容式聚合物濕度傳感器的校正方法需要相當的校正點,造成時間成本與人力成本的消耗,進而壓低利潤或提高產品價格而降低競爭力的缺點,本發明提供一種濕度傳感器的校正方法,在校正相同規格的多個濕度傳感器時,能透過使用較少的校正點,節省時間成本與人力成本,提高廠商利潤及提高產品競爭力。The present invention provides a humidity in view of the fact that the conventional high-precision capacitive polymer humidity sensor calibration method requires a considerable correction point, resulting in consumption of time cost and labor cost, thereby reducing profit or increasing product price and reducing competitiveness. The sensor calibration method can save time and labor costs, improve manufacturer's profit and improve product competitiveness by correcting multiple humidity sensors of the same specification by using fewer calibration points.
該濕度傳感器的校正方法係包含有以下步驟: 檢測同一規格下的其中一個濕度傳感器的複數個校正點;其中各該校正點係分別包含一目前環境濕度值及其對應的電容值; 根據該些校正點計算一第一共同轉換函數式的係數及一第二共同轉換函數式的係數;其中該第一共同轉換函數式係對應該同一規格下的所有濕度傳感器;其中該第二共同轉換函數式係對應該同一規格下的所有濕度傳感器;其中該第一共同轉換函數式係一濕度值對電容值的轉換函數式,該第二共同轉換函數式係一電容值對濕度值的轉換函數式; 針對同一規格下的各個濕度傳感器係分別透過一係數計算程序計算各自的一各別轉換函數式的係數;其中該各別轉換函數式係一週期值對電容值的轉換函數式; 針對同一規格下的各個濕度傳感器係分別透過一校正程序計算各個濕度傳感器的目前濕度。The method for correcting the humidity sensor includes the following steps: detecting a plurality of calibration points of one of the humidity sensors in the same specification; wherein each of the calibration points includes a current ambient humidity value and a corresponding capacitance value thereof; The correction point calculates a coefficient of a first common conversion function and a coefficient of a second common conversion function; wherein the first common conversion function corresponds to all humidity sensors in the same specification; wherein the second common conversion function Corresponding to all the humidity sensors in the same specification; wherein the first common conversion function is a conversion function of a humidity value to a capacitance value, and the second common conversion function is a conversion function of a capacitance value to a humidity value; For each humidity sensor under the same specification, each coefficient of each conversion function is calculated by a coefficient calculation program; wherein the respective conversion function is a conversion function of a period value to a capacitance value; Each humidity sensor calculates the current state of each humidity sensor through a calibration program humidity.
透過本發明的傳感器校正方法,在對相同規格的濕度傳感器進行校正時,只需針對其中一個濕度傳感器取該些校正點,並透過該些校正點計算出該第一共同轉換函數式的係數及該第二共同轉換函數式的係數。並針對相同規格的各個濕度傳感器透過該係數計算程序即可計算出各自的各別轉換函數式的係數。當各個濕度傳感器需要感測濕度時,只需透過該校正程序計算出目前濕度,且計算出的目前濕度已經過校正,具有較高的精度。According to the sensor calibration method of the present invention, when the humidity sensor of the same specification is corrected, only the correction points are taken for one of the humidity sensors, and the coefficients of the first common conversion function are calculated through the correction points and The coefficients of the second common conversion function. The coefficients of the respective conversion function formulas can be calculated by the coefficient calculation program for each humidity sensor of the same specification. When each humidity sensor needs to sense the humidity, only the current humidity is calculated through the calibration program, and the calculated current humidity has been corrected, with high precision.
此外,本發明的傳感器校正方法,在校正相同規格的整批濕度傳感器時,只需針對其中一個濕度傳感器取該些校正點,對於相同規格的其餘濕度傳感器而言,只需透過該係數計算程序即可計算出對應函數式。並不需要針對每一個濕度傳感器都取該些校正點,藉此大幅減少校正整批相同規格的濕度傳感器時所需的校正點數量,且能維持一定的精準度,以節省時間成本與人力成本,提高廠商利潤及提高產品競爭力。In addition, the sensor calibration method of the present invention only needs to take the correction points for one of the humidity sensors when correcting the whole batch of humidity sensors of the same specification, and for the remaining humidity sensors of the same specification, only the coefficient calculation program is required. The corresponding functional formula can be calculated. It is not necessary to take these correction points for each humidity sensor, thereby greatly reducing the number of correction points required to correct the entire batch of humidity sensors of the same specification, and maintaining a certain degree of precision to save time and labor costs. Improve the profit of manufacturers and improve the competitiveness of products.
以下配合圖式及本發明較佳實施例,進一步闡述本發明為達成預定目的所採取的技術手段。The technical means adopted by the present invention for achieving the intended purpose are further explained below in conjunction with the drawings and preferred embodiments of the present invention.
請參閱圖1所示,本發明係一種濕度傳感器的校正方法,該濕度傳感器的校正方法係包含有以下步驟: 檢測同一規格下的其中一個濕度傳感器的複數校正點 (S101);其中各該校正點包含一目前環境濕度值及其對應的電容值; 根據該些校正點計算一第一共同轉換函數式的係數及一第二共同轉換函數式的係數(S102);其中該第一共同轉換函數式係對應該同一規格下的所有濕度傳感器;其中該第二共同轉換函數式係對應該同一規格下的所有濕度傳感器; 針對同一規格下的各個濕度傳感器係分別透過一係數計算程序計算各自的一各別轉換函數式的係數(S103); 針對同一規格下的各個濕度傳感器係分別透過一校正程序計算各個濕度傳感器的目前濕度(S104)。Referring to FIG. 1 , the present invention is a method for correcting a humidity sensor. The method for correcting the humidity sensor includes the following steps: detecting a complex correction point of one of the humidity sensors in the same specification (S101); wherein the correction is performed The point includes a current ambient humidity value and a corresponding capacitance value thereof; calculating a coefficient of a first common conversion function formula and a coefficient of a second common conversion function formula according to the correction points (S102); wherein the first common conversion function The system corresponds to all the humidity sensors under the same specification; wherein the second common conversion function type corresponds to all the humidity sensors under the same specification; for each humidity sensor under the same specification, each of the humidity sensors is calculated by a coefficient calculation program. The coefficient of each conversion function formula (S103); The humidity of each humidity sensor is calculated by a correction program for each humidity sensor under the same specification (S104).
在本較佳實施例中,該第一共同轉換函數式係一濕度值對電容值的轉換函數式,該第二共同轉換函數式係一電容值對濕度值的轉換函數式,而該各別轉換函數式係一週期值對電容值的轉換函數式。In the preferred embodiment, the first common conversion function is a conversion function of a humidity value to a capacitance value, and the second common conversion function is a conversion function of a capacitance value to a humidity value, and the respective The conversion function is a conversion function of a period value to a capacitance value.
在本較佳實施例中,在步驟「檢測同一規格下的其中一個濕度傳感器的複數個校正點」後,係進一步剔除該些校正點的數據統計分布中最高20%和最低20%後,根據剩餘的校正點計算該第一共同轉換函數式的係數及該第二共同轉換函數式的係數。In the preferred embodiment, after the step of "detecting a plurality of correction points of one of the humidity sensors under the same specification", the data is further removed by a maximum of 20% and a minimum of 20% of the statistical distribution of the correction points, according to The remaining correction points calculate the coefficients of the first common transfer function formula and the coefficients of the second common transfer function formula.
在本較佳實施例中,本發明係透過一檢測電路檢測該濕度傳感器的電容值,並轉換成一感測訊號後輸出,而該檢測電路輸出的感測訊號的週期值會隨著檢測到的電容值改變,因此,可透過該感測訊號的週期值反推出檢測到的電容值。故本發明讀取的是該感測訊號的週期值,並可根據該週期值計算出校正後的目前濕度。In the preferred embodiment, the present invention detects the capacitance value of the humidity sensor through a detecting circuit and converts it into a sensing signal for output, and the period value of the sensing signal output by the detecting circuit is detected. The capacitance value changes, so the detected capacitance value can be deduced by the period value of the sensing signal. Therefore, the present invention reads the period value of the sensing signal, and can calculate the corrected current humidity according to the period value.
舉例來說,本發明以N個校正點為例說明,N為大於1的正整數。該第一共同轉換函數式及該第二共同轉換函數式分別是一四階多項式,且N可為10(十個校正點),而剔除數據統計分布中最高20%和最低20%後的校正點數量為六個。For example, the present invention exemplifies N correction points, where N is a positive integer greater than one. The first common transfer function formula and the second common transfer function formula are respectively a fourth-order polynomial, and N can be 10 (ten correction points), and the correction after culling the highest 20% and the lowest 20% in the statistical distribution of the data The number of points is six.
剔除數據統計分布中最高20%和最低20%後的校正點如下表所示:The correction points after removing the highest 20% and the lowest 20% of the statistical distribution are shown in the following table:

而在計算該第一共同轉換函數式的係數及該第二共同轉換函數式的係數時,係透過將上述該N個校正點代入該第一共同轉換函數式中解聯立方程式而獲得該些係數,如上述的A、B、C、D、E,且透過將上述該N個校正點代入該第二共同轉換函數式中解聯立方程式而獲得該些係數,如上述的F、G、H、I、J。And calculating the coefficients of the first common conversion function formula and the coefficients of the second common conversion function formula, and obtaining the coefficients by substituting the N correction points into the first common conversion function formula. As described above, A, B, C, D, and E, and obtaining the coefficients by substituting the N correction points into the second common conversion function formula, such as F, G, H, I, J.
透過本發明的傳感器校正方法,在對相同規格的濕度傳感器進行校正時,只需針對其中一個濕度傳感器取該N個校正點,並透過該N個校正點計算出該第一共同轉換函數式的係數及該第二共同轉換函數式的係數。並針對相同規格的各個濕度傳感器透過該係數計算程序即可計算出各自的各別轉換函數式的係數。當各個濕度傳感器需要感測濕度時,只需透過該校正程序計算出目前濕度,且計算出的目前濕度已經過校正,具有較高的精度。According to the sensor calibration method of the present invention, when the humidity sensor of the same specification is corrected, only the N correction points are taken for one of the humidity sensors, and the first common conversion function is calculated through the N correction points. The coefficient and the coefficient of the second common conversion function. The coefficients of the respective conversion function formulas can be calculated by the coefficient calculation program for each humidity sensor of the same specification. When each humidity sensor needs to sense the humidity, only the current humidity is calculated through the calibration program, and the calculated current humidity has been corrected, with high precision.
此外,本發明的傳感器校正方法,在校正相同規格的整批濕度傳感器時,只需針對其中一個濕度傳感器取該N個校正點,對於相同規格的其餘濕度傳感器而言,只需透過該係數計算程序即可計算出對應函數式。並不需要針對每一個濕度傳感器都取N個校正點,藉此大幅減少校正整批相同規個的濕度傳感器時所需的校正點數量,且能維持一定的精準度,以節省時間成本與人力成本,提高廠商利潤及提高產品競爭力。In addition, the sensor calibration method of the present invention only needs to take the N calibration points for one of the humidity sensors when correcting the whole batch of humidity sensors of the same specification, and for the remaining humidity sensors of the same specification, only the coefficient is calculated. The program can calculate the corresponding function. It is not necessary to take N calibration points for each humidity sensor, thereby greatly reducing the number of correction points required to correct the entire batch of the same gauge humidity sensor, and maintaining a certain degree of precision to save time and labor. Cost, increase manufacturers' profits and improve product competitiveness.
請參閱圖2所示,該係數計算程序係包含有以下步驟: 透過該第一共同轉換函數式計算一第一點濕度值下的一第一點電容值(S1031); 透過該第一共同轉換函數式計算一第二點濕度值下的一第二點電容值(S1032); 檢測於該第一點濕度值下的一第一點週期值(S1033); 檢測於該第二點濕度值下的一第二點週期值(S1034); 根據該第一點電容值、第一點週期值、該第二點電容值及該第二點週期值計算該各別轉換函數式的係數(S1035)。Referring to FIG. 2, the coefficient calculation program includes the following steps: calculating a first point capacitance value at a first point humidity value by using the first common conversion function formula (S1031); transmitting the first common conversion The function calculates a second point capacitance value at a second point humidity value (S1032); detects a first point period value at the first point humidity value (S1033); detects the second point humidity value a second period value of the second period (S1034); calculating a coefficient of the respective conversion function formula according to the first point capacitance value, the first point period value, the second point capacitance value, and the second point period value (S1035) .
舉例來說,該第一點濕度值為70%,該第二點濕度值為30%。而該各別轉換函數式如下所示:For example, the first point humidity value is 70% and the second point humidity value is 30%. The respective conversion function is as follows:
上述的c為電容值,p為週期值,a、b為函數式係數。The above c is a capacitance value, p is a period value, and a and b are functional coefficients.
在各別轉換函數式的係數時,係透過將上述第一點電容值、第一點週期值代入該各別轉換函數式中,且將上述該第二點電容值及該第二點週期值代入該各別轉換函數式後,解聯立方程式而獲得該些係數,如上述的a、b。When each of the coefficients of the functional formula is converted, the first point capacitance value and the first point period value are substituted into the respective conversion function formula, and the second point capacitance value and the second point period value are used. After substituting the respective conversion function formulas, the cubic equations are decomposed to obtain the coefficients, such as a and b above.
請參閱圖3所示,該校正程序係包含有以下步驟: 檢測目前週期值(S1041); 透過該各別轉換函數式計算在該目前週期值下的目前電容值(S1042); 透過該第二共同轉換函數式計算在該目前電容值下的目前濕度值(S1043)。Referring to FIG. 3, the calibration procedure includes the following steps: detecting a current period value (S1041); calculating a current capacitance value at the current period value by using the respective conversion function formula (S1042); The common conversion function calculates the current humidity value at the current capacitance value (S1043).
在本較佳實施例中,根據目前週期值透過各別轉換函數式計算出的目前電容值的單位不限定為皮法(pF),只要是任何能表示電容值的單位皆可。In the preferred embodiment, the unit of the current capacitance value calculated by the current transition value through the respective conversion function formula is not limited to the picofarad (pF), and any unit capable of expressing the capacitance value may be used.
由此可知,本發明的傳感器校正方法,在針對相同規格的各個濕度傳感器透過該係數計算程序即可計算出各自的各別轉換函數式的係數時,只需透過該第一點濕度值及該第二點濕度值,兩個校正點即可計算出該轉換函數式的係數。且在各個濕度傳感器需要感測濕度時,只需透過該各別轉換函數式即可計算出校正過的目前濕度。如此一來,針對相同規格的同一批濕度傳感器只需檢測其中一個濕度傳感器的該N個的校正點,對於相同規格同一批的其餘濕度傳感器只需分別偵測二個校正點即可計算出各自的各別轉換函數式的係數。當需要感測目前濕度時,能計算出校正後的濕度值。藉此節省時間成本與人力成本,提高廠商利潤及提高產品競爭力。Therefore, the sensor calibration method of the present invention can calculate the coefficients of the respective conversion function formulas by using the coefficient calculation program for each humidity sensor of the same specification, and only need to transmit the first point humidity value and the The second point of humidity value, two correction points can calculate the coefficient of the conversion function. Moreover, when each humidity sensor needs to sense the humidity, the corrected current humidity can be calculated only through the respective conversion function formula. In this way, for the same batch of humidity sensors of the same specification, only the N calibration points of one of the humidity sensors need to be detected. For the remaining humidity sensors of the same batch of the same specification, only two calibration points need to be detected separately to calculate respective The coefficients of the individual conversion functions. When it is necessary to sense the current humidity, the corrected humidity value can be calculated. This saves time and labor costs, increases vendor profitability and improves product competitiveness.
請參閱圖4及圖5所示,本發明的校正方法係由一濕度校正系統所執行,該濕度校正系統係包含有一濕度傳感器10、一檢測電路20、一處理器30及一顯示器40。Referring to FIG. 4 and FIG. 5, the calibration method of the present invention is implemented by a humidity correction system including a humidity sensor 10, a detection circuit 20, a processor 30, and a display 40.
該濕度傳感器10係用於感測目前環境濕度,並產生一目前電容訊號,由該目前電容訊號反映該目前環境濕度。該檢測電路20係電連接至該濕度傳感器10,以接該目前電容訊號,並產生一感測訊號。該處理器30係電連接至該檢測電路20及該顯示器40,並根據該感測訊號的週期值,透過執行本發明的校正方法計算出目前濕度值,並將該目前濕度值傳送至該顯示器40顯示。The humidity sensor 10 is configured to sense the current ambient humidity and generate a current capacitive signal, the current capacitive signal reflecting the current ambient humidity. The detecting circuit 20 is electrically connected to the humidity sensor 10 to connect the current capacitive signal and generate a sensing signal. The processor 30 is electrically connected to the detecting circuit 20 and the display 40, and calculates a current humidity value by performing the calibration method of the present invention according to the period value of the sensing signal, and transmits the current humidity value to the display. 40 shows.
請參閱圖6及圖7所示,一般的兩點校正方式是針對各個濕度傳感器分別取兩個校正點進行轉換函數的係數計算,但只取兩個校正點所能計算出的轉換函數式最多只能為一階的轉換函數式,其精準度較低。Referring to FIG. 6 and FIG. 7 , the general two-point calibration method is to calculate the coefficients of the conversion function by taking two correction points for each humidity sensor, but only the two conversion points can calculate the conversion function. It can only be a first-order conversion function with low precision.
但本發明的校正方法所執行的兩點校正方式是先透過該N個校正點計算出高階的該第一共同轉換函數式及該第二共同轉換函數式後,在利用該第一共同轉換函數式計算出各個濕度傳感器的一階的各別轉換函數式,因此在進行校正程序時,與一般的兩點校正方式相比,能具有較高的精準度。However, the two-point correction method performed by the correction method of the present invention is to first calculate the first common conversion function formula and the second common conversion function formula through the N correction points, and then utilize the first common conversion function. The formula calculates the first-order individual conversion function of each humidity sensor, so that it can have higher accuracy than the general two-point correction method when performing the calibration procedure.
如圖6所示,本發明計算出的量測濕度與實際濕度的關係曲線幾乎為一標準的斜直線,代表透過本發明計算出的量測濕度與實際濕度幾乎相同,因此如圖7所示,在誤差濕度的表現上,幾乎沒有誤差(0%)。而一般的兩點校正方式,雖有校正效果,但如圖6及圖7所示,一般的兩點校正方式計算出的量測濕度與實際濕度的關係曲線在低濕度時,就有所偏離,且如圖7所示,在低濕度時的誤差濕度亦相對大。因此,無論是在量測濕度與實際濕度相比的準確度,或是在誤差濕度的表現上,本發明皆有較佳的成效,由此可知,本發明的校正方法與一般的兩點校正方式相比,亦能提高精準度。As shown in FIG. 6, the relationship between the measured humidity and the actual humidity calculated by the present invention is almost a standard oblique line, which means that the measured humidity calculated by the present invention is almost the same as the actual humidity, so as shown in FIG. There is almost no error (0%) in the performance of the error humidity. However, the general two-point calibration method has a correction effect, but as shown in FIG. 6 and FIG. 7, the relationship between the measured humidity and the actual humidity calculated by the general two-point calibration method deviates at a low humidity. And as shown in Fig. 7, the error humidity at low humidity is also relatively large. Therefore, the present invention has a better effect both in measuring the accuracy of the humidity compared to the actual humidity or in the performance of the error humidity, and thus the correction method of the present invention and the general two-point correction are known. Compared with the method, it can also improve the accuracy.
