| Summary: | A masterslave synchronous timing mode implementation method of revolving speed measurement is put forward based on different M/T aimed at the rotating machinery in this paper The MCU is set to make two timers synchronously count and cooperatively work, and the external trigger pulse generating circuit is designed The external trigger can start the two timers at the same time, and the master timer can stop the slave timer under the condition of counting terminate that makes the two timers achieve synchronization The counting value of master timer can be dynamically set according to the current speed, which makes this method suitable for high speed and low speed measurement applications Experimental results show that the relative measurement error of this method is less than 02‰, has wide measurement range of 5 r/min~20.000r/min, and the processing routine is simple, easy to implement |
