Disclosed are a method, a system and a medical device for compressing a physiological signal suitable for the bio-medical device field. The method for compressing a physiological signal comprises: acquiring a physiological signal (S101); adaptively segmenting the acquired physiological signal to obtain corresponding homogeneous segments (S103); and compressing the obtained homogeneous segments (S105), wherein data compression is performed on the physiological signal by adaptively selecting a corresponding data compression method by using the consistency of the local physical properties of a physiological signal and the difference between various parts, thus resulting in a method, a system and a medical device for compressing a physiological signal, and enabling the compression of data to a relatively large extent and full retention of the physiological signal.
Description
Technical field [0001] The invention belongs to the field of biomedical equipment, and particularly relates to a physiological signal compression method, system and medical equipment. Background technique [0002] The existing compression algorithms related to physiological signals are mainly divided into two categories: lossless physiological signal compression and lossy physiological signal compression. Lossless physiological signal compression mainly uses general signal compression methods, such as Huffman coding, arithmetic coding, dictionary-based Lz series coding methods, and combinations of the above-mentioned codes for data compression. Lossy physiological signal compression mainly uses polyline approximation, fan-shaped area approximation, and transform methods such as wavelet transform and principal component transform for data compression. The general lossless physiological signal compression algorithm can compress the data to a certain extent, but it uses a grammar-b...
