Abstract
The present invention discloses a pulse frequency measurement device and method and a control system, the device including: a hardware counter configured to perform a counting operation on an input pulse sequence to output a counting result; and a processing unit configured to obtain number of pulses from the counting result outputted by the hardware counter and measure a first time period during which the obtained number of pulses occupy, in which the processing unit includes a frequency calculation module configured to calculate a frequency of the input pulse sequence based on the obtained number of pulses and the first time period. According to the invention, it is possible to achieve adaptive pulse frequency measurement and multi-channel sampling for multiple input pulse sequences with a relatively low cost while ensuring the accuracy of the measurement result.
