[0002] Cardiac shock is a graph that describes the weak movement of the body caused by the impact and rebound of the heart and great blood vessels when the heart is active and the blood is running. The existing detection method for the validity of the time series signal of the ballistocardiogram needs to traverse the search space forward in real time. And in this search space, the judgment is forced, so the location error of the timing signal of the ballistocardiogram obtained in the case of interference is relatively large, so the timing signal of the ballistocardiogram obtained is likely to be an invalid timing signal of the ballistocardiogram, while the prior art It is also impossible to accurately detect the validity of the corresponding ballistocardiogram timing signal

The invention provides a method for detecting the validity of the shockcardiogram sequence signal. In order to realize the real-time positioning of the shockcardiogram signal, the shockcardiogram sequence in the buffer zone is cut into several sub-segments at equal intervals, and the respiration and body movement interference are eliminated in preprocessing. On the basis of that, a J-peak localization method based on the correlation localization of the temporal-series signal template of the ballistocardiogram and the localization of the morphological distance is proposed. At the same time, under the effective constraint conditions, the sequential localization of the J-peak of the temporal-series signal of the ballistocardiogram is realized one by one.
Description
technical field [0001] The invention relates to the technical field of the validity detection of the ballistocardiogram time series signal, in particular to a validity detection method of the ballocardiogram time series signal. Background technique [0002] Cardiac shock is a graph that describes the weak movement of the body caused by the impact and rebound of the heart and great blood vessels when the heart is active and the blood is running. The existing detection method for the validity of the time series signal of the ballistocardiogram needs to traverse the search space forward in real time. And in this search space, the judgment is forced, so the location error of the timing signal of the ballistocardiogram obtained in the case of interference is relatively large, so the timing signal of the ballistocardiogram obtained is likely to be an invalid timing signal of the ballistocardiogram, while the prior art It is also impossible to accurately detect the validity of the ...
