Problems solved by technology
[0002] At present, the total power consumption of the system is considered from the design of the vibration inspection instrument. In order to reduce power consumption, the MCU with lower power consumption is generally selected from the chip selection, but it is difficult for the MCU to realize the Fourier transform of the vibration signal; and the support is completed. High-performance chips for Fourier transform of vibration signals need to consume high current, which is a challenge for low-power vibration detectors

The invention relates to a vibration inspection instrument, a low-power frequency domain conversion method thereof, and a computer-readable storage medium. The vibration inspection instrument includes an acquisition module, which is used to collect peripheral signals of the vibration inspection instrument; a low-power main control module, which records the signals; and a high-performance auxiliary module that is normally turned off, which periodically is enabled to perform a frequency domain transform on said signal recorded during said period. Since the time-consuming collection tasks are handled by the low-power main control module, the auxiliary modules with higher energy consumption are only occasionally started to perform frequency domain conversion, and the frequency domain conversion time is short, so the auxiliary modules with higher energy consumption will not consume too much energy , making the vibration inspection instrument realize low power consumption operation.
Description
technical field [0001] The invention relates to the technical field of signal detection, in particular to a vibration inspection instrument, a low-power frequency domain transformation method thereof, and a computer-readable storage medium. Background technique [0002] At present, the total power consumption of the system is considered in the design of the vibration inspection instrument. In order to reduce power consumption, the MCU with lower power consumption is generally selected from the chip selection, but it is difficult for the MCU to realize the Fourier transform of the vibration signal; and the support is completed High-performance chips for Fourier transform of vibration signals need to consume high current, which is a challenge for low-power vibration detectors. Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a vibration inspection instrument, a low power consumption measurement method thereof, and...
