Abstract

The present invention is applicable to the technical field of data compression, and provides a quality-guaranteed compression method, device, and terminal equipment for physiological monitoring data. The method includes: obtaining the original data value of the target monitoring data; and calculating the The initial compressed data of the target monitoring data; according to the initial compressed data and the preset error limit, calculate the error data interval corresponding to the initial compressed data; according to the preset search rules, determine the data included in the error data interval from the preset data to be searched The data to be searched is used as compressed data, and the coefficients of the data to be searched are stored in the first sequence; according to the preset marking rules, the compressed data is used to assign values ​​to the marking sequence. The quality-guaranteed compression method of physiological monitoring data provided by the present invention can independently compress each target monitoring data, has good real-time performance and high compression efficiency, and effectively reduces power consumption of data transmission in the physiological data monitoring process.

Description

technical field [0001] The invention belongs to the technical field of data compression, and in particular relates to a quality-guaranteed compression method, device and terminal equipment for physiological monitoring data. Background technique [0002] Physiological monitoring data includes streaming data such as EEG data and ECG data, which are usually sequential, large, fast, and continuously arriving data sequences. Such streaming data can be viewed as a dynamic collection of data that grows over time and has important implications in the medical field. Dynamic EEG and ECG and other physiological data maps are commonly used clinical methods for cardiovascular disease screening and condition monitoring. Continuous physiological data can be used as an important basis for diagnosis and evaluation. [0003] In the process of acquiring and analyzing physiological monitoring data, in order to prolong the battery life of the monitoring system and achieve long-term and stable m...
