摘　　要：针对光纤传感器测量系统中的准确性和实时性的问题,首先深入研究了基于算术平均值与递推估计相结合的实时数据处理方法;在此基础上,采用DSP芯片TMS320VC33,设计出一种结构简单的光电转换器;最后,介绍了部分实验系统实现与结果.实验表明,该方法简化了设计,提高了测量精度和可靠性,满足了测量系统的实时性,有利于工程的实际应用.To solve the question of veracity and real-time in optical fiber sensor measurement system, the method of real-time data processing which based on arithmetic average and recurrence estimation was firstly studied. Then adopting DSP chip TMS320VC33, a new simple photoelectric converter was designed based on these. Finally, some realization and results of experiment system were demonstrated. The results indicate the photoelectric converter using this method can simplifie design, improve measurement precision and reliability and meet the demands of real time. The system is suitable for the application.
