摘　　要：详细介绍了有关非线性传感器智能线性化校正的分析方法,以铂电阻非线性特性为例提出三种线性化校正方法,即查表法、数学公式法和比例系数法。可以根据实际测量范围和测量精度的要求选用不同的线性校正方法。在实际电路设计过程中使用前两种方法,得到了很好的线性化结果。在一些应用传感器较多的场合,基于计算机平台完全通过软件开发的虚拟智能线性化传感器,由于其性价比高、使用方便、维护简单、功能扩展容易等优点,非常适合于推广应用。This paper presents the corrected analysis method about non-linear sensor intelligent linearization in detail, and on the basis platinum resistance non-linear characteristics, presents three kinds of linear corrected methods, look-up table, math formula and scale coefficient. The different corrected method can be selected according to the actual measurement range and measurement accuracy. The first two methods provide very good linear results in the actual process of circuit design. In some conditions where more sensor are used, the computer-based platforms are virtual intelligent linear sensors that are developed completely with software, which are adaptable to be popularized widely for the advantages of high performance-cost ratio, convenient application, simple maintenance and easy to be extended.
