Beschreibung
Zusammenfassung:	The invention provides a drilling fluid continuous wave smooth phase modulation method and system. The method comprises the steps that a target continuous wave signal is determined according to underground information collected by an underground sensor; determining a rotation angle required by a driving motor in a current carrier period corresponding to the underground information according to a preset modulation rule; according to a preset speed planning method, the rotating speed change trend of the driving motor in the current carrier period corresponding to the underground information is determined; in combination with a modulation rule and a speed planning method, the rotating speed of the driving motor is smoothed under the condition that the continuous wave signal phase changes according to a set traditional rule, and meanwhile the movement continuity of the driving motor is guaranteed; according to the target continuous wave signal, the rotation angle required by the driving motor and the rotation spe
