This invention discloses a method and system for determining the current time using radio observations of multiple pulsars, comprising the following steps: S1. Correcting the deviation between the local clock time and the absolute time to within a set threshold; S2. Selecting N radio pulsars, where N is greater than or equal to 4, and continuously observing the selected radio pulsars using a radio telescope to obtain observation data; S3. Processing the observation data to generate the observed pulse profile; calculating the pulsar pulse phase φ. i S4. Calculate the standard pulse profile P k With the observed pulse profile P' k The relative phase deviation δφ between i Calculate the relative phase deviation δφ with error S5. i With phase φ i deviation Δφ i S6. The deviation δT between the telescope's local clock time and absolute time is calculated, thereby determining the absolute time. This invention eliminates the need to synchronize the local clock with the absolute time of a certain time standard. It can obtain absolute time with an accuracy on the order of tens of microseconds by analyzing observed pulsars, and significantly reduces calculation time.

This invention discloses a high-precision waveform curve support method, system, device, and storage medium based on ScottPlot, comprising: determining the base time of waveform data points; calculating the time interval by subtracting the base time from the original time of the waveform data points, converting the time interval into a total number of milliseconds, and using the total number of milliseconds as the millisecond offset; using the millisecond offset as the X-axis coordinate data source, and combining it with the original ordinate value of the waveform data points to draw the waveform curve in the ScottPlot chart frame; upon receiving a trigger command to display the real time of the waveform data points, obtaining the millisecond offset of the current data point on the X-axis, adding the millisecond offset to the base time to calculate and reconstruct the real time for display. This enables ScottPlot to support the display of high-precision curves, with precision down to the microsecond or even nanosecond level.
