| 摘 要： | 介绍了ZMD公司的ZMD31050补偿芯片在压力测量中解决温度漂移方面的应用实例。首先阐述了ZMD31050进行补偿的基本原理，包括工作时的信号流图和信号调理算法。接着给出了基于低功耗的C8051F930为主控芯片的硬件电路的搭建方法及软件部分的设计，其中芯片之间的通信采用了FC协议。最后通过实验结果可以看出，ZMD31050对温度的漂移进行补偿后，原有误差明显降低，可见其效果是较理想的。

| Abstract: | The paper introduces an application of compensation to temperature drift in pressure measuring based on the ZMD31050 chip.The principle of compensation,including the signal flow and the signal conditioning is described.The hardware construction based on the low-power MCU C8051F930 and software design are also provided in this paper.From the experiment,we can see the compensation application,which reduces the error in an obvious scale,is effective. |
