| 摘 要： | 标定是保证传感器测量精度的重要手段。这里针对离子浓度传感器（ISE）的两点标定法、多点分段标定法以及最终提出的最小二乘标定法进行了数学建模和标定误差分析。提出以标定误差最小的原则,作为标定方法的选择依据;以标定曲线的斜率来判断ISE的老化程度、且进行脸谱表情显示。经理论分析和实验证明,最小二乘标定法在这里提及方法中能到达标定误差最小。并且,该方法已经在具体的硬件平台实现。

| Abstract: | Calibration is an important way in keeping the measurement accuracy of sensor.Mathematical modeling and calibration error analysis on two-point calibration,multi-point calibration,and least-square calibration are given in the paper.In addition,calibration error least is taken as the standard for calibration method selection and the slope of calibration curve for judging the ISE aging degree and facebook expression.Theoretical analysis and experiments indicate that the least-square,calibration proposed in th... |
