Device and method for noise identification and parameter adjustment in PTP clock network

The invention provides a device for noise identification and parameter adjustment in a PTP clock network, and the device comprises a message processing module which is electrically connected with a PTP module, a fast Fourier transform module, and a PID module, and the PID parameter adjustment module is electrically connected with the fast Fourier transform module, and the PID module. The PTP module is used for sending a PTP message containing noise information and time information to the message processing module; the message processing module is used for extracting time deviation information of the PTP message and sending the time deviation information to the fast Fourier transform module; the fast Fourier transform module is used for determining a noise amplitude and a noise frequency value according to the time deviation information and sending the noise amplitude and the noise frequency value to the PID parameter adjustment module; the PID parameter adjustment module is used for determining a correspondin
