摘　　要：克服传统的通过硬件电路来对压力传感器进行温度误差补偿的缺点,介绍利用单片机进行压力传感器温度补偿的基本方法,论述如何利用软件进行温度误差补偿的方法,详细描述高精度温度补偿的软件算法原理,为实现通过软件进行温度补偿提供了理论依据。通过实验测试证明了采用高精度温度补偿算法的传感器输出精度有了显著的提高。In order to overcome the shortcomings of traditional hardware circuits for the pressure sensor temperature com-pensation,the basic method using single chip processor for pressure sensor temperature compensation is introduced. The method to implement temperature compensation by software is discussed. The principle of software algorithm for high-accuracy tempera-ture compensation is expatiated,which provides a theoretical basis for temperature compensation by software. The experiment re-sults prove that the sensor output accuracy has been significantly improved by the high-accuracy temperature compensation algo-rithm.
