摘要
Abstract
The frequency measuring module is designed for distributed control system.It is one of the components of distributed control System's input and output cards used in conjunction with the distributed processing unit,which cannot work alone,and send the measurement data to DPU via UART.Taking STM32 with new high-performance ARM 32-bit Cortex-M3 core as the controller core,proposing the frequency measuring principle and method based on MCU,and fusion the frequency measuring method and the period measuring method.Practical application shows that the card has good real-time performance and high measurement accuracy,meeting design requirements.关键词
