An electrocardiogram waveform rapid compression algorithm suitable for realizing real-time transmission in embedded hardware

Abstract

An electrocardiogram waveform rapid compression algorithm suitable for achieving real-time transmission in embedded hardware comprises the following steps that S1, a certain change rule is provided for electrocardiogram waveforms, and a large number of data points are based on the vicinity of a base line, so that one-time differential compression and two-time statistical coding compression are carried out on data; S2, before actual compression, the acquired electrocardiogram waveform data is grouped according to a fixed time period, firstly compression values Ci of primary compression and secondary compression of each group of data is calculated respectively, and the compression values C2 of the secondary compression is compared with the compression values C1 of the secondary compression;S3, if the compression value C2 of the double compression is lower than the single compression value C1, actual compression is performed by using the double compression, otherwise, the single compression is directly used; S4, according to the selected compression multiples, electrocardiogram waveform data compression calculation is carried out; And S5, the data receiving end carries out electrocardiogram waveform data decompression calculation through inverse operation in the compression step according to the selected compression multiples.

Description

technical field [0001] The invention relates to a fast compression algorithm for electrocardiographic waveforms suitable for real-time transmission in embedded hardware, and belongs to the technical field of electrocardiographic signal processing. Background technique [0002] Nowadays, monitoring instruments related to vital signs are more popular in clinical applications. It can monitor vital signs such as ECG, blood pressure, and respiration of bedridden patients, especially postoperative patients, or critically ill patients in real time. Knowing one's own health status will also help doctors to understand the patient's condition in time so as to take more effective treatment methods. With the improvement of the aging society, more and more elderly people need long-term medical monitoring at home, especially some people who have long-term chronic senile diseases or those who have been bedridden for a long time need to monitor some of his vital signs regularly. Monitor yo...

However, its computing power is weak and the available resources are less

In addition, with the continuous update of the Internet and Internet of Things technology, the data transmission performance of the network is continuously improved, but due to its particularity, the mobile network still has a small amount of data transmission and high costs.
