摘　　要：频率测量在电子工程领域、医学领域有着广泛应用,为了提升在测量过程中系统的动态监测性能、获取频率的动态变化,文章提出了一种带回显和校准功能的多功能动态测频仪设计。该多功能动态测频仪具有测频、测温、时间显示等基本功能,用户通过按键实现功能切换和参数设置;当频率测量结果的变化超过设置范围时,触发AT24C02记录此频率结果以及发生时间,计算和记录平均频率,供用户翻查;还能通过按键调整校准值,实现测量结果的自动校准和修正。实验测试结果表明,该多功能动态测频仪能够准确检测频率测量的动态变化,测量精度高,参数稳定,可用于医学领域的动态心率监测、汽车故障动态信号的诊断监测等场合,为病情或故障判断提供参数依据。Frequency measurement has a wide range of applications in the fields of electronic engineering and medicine.In order to improve the dynamic monitoring performance of the system and obtain the dynamic changes of frequency during the measurement process,this article proposes a multifunctional dynamic frequency meter design with display and calibration functions.This design has basic functions such as frequency measurement,temperature measurement,and time display,which can be switched and parameter settings can be achieved through buttons.When the frequency measurement result changes beyond the set range,this design triggers AT24C02 to record the frequency result and occurrence time,and calculates and records the average frequency for users to review.This design can adjust the calibration value through buttons to achieve automatic calibration and correction of measurement results.The experimental test results show that this system can accurately detect the dynamic changes in frequency measurement,with high measurement accuracy and stable parameters.It can be used for dynamic heart rate monitoring in the medical field,diagnosis and monitoring of dynamic signals of automotive faults,and other occasions,providing parameter basis for disease or fault diagnosis.
