| Abstract: | In view of the shortcomings of big volume,bad accuracy and so forth of common tachometer,a systematic structure and designing method for infrared and digital tachometer centering on single chip computer are presented.Signal detection,protection of data,time controlling and the choice of parameters are discussed.On the basis of PIC16F873,circuit principle for rotational speed and calendar clocks can be realized.By functional enlargement,this system can also be used in other fields. |
