Embodiment Construction

[0036] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0037] Such as figure 1 As shown, the specific embodiment of the present invention is: provide a kind of electrocardiographic signal transmission method based on wavelet algorithm, comprise the steps:

[0038] Step 100: collecting ECG data, that is, collecting ECG signals and converting them into HL7 standard data and MFER standard waveform data. The specific process is as follows: collect ECG data from multiple ECG signal terminals, convert the collected ECG data into HL7 standard data and MFER standard waveform data, and then transmit the data in HL7 / MFER format to remote server.

[0039] Step 200: Transformation of ECG data, namely: setting the soft threshold value of wavelet coefficient processing according to the terminal display size parameter to truncate the wavelet coefficients, performing discrete wavelet transform on the ECG data accor...

Abstract

The invention relates to a wavelet algorithm-based electrocardiogram (ECG) signal transmission method and a system, wherein the optimized real-time compression for ECG signals which is adaptable to the display size of a mobile terminal, a link real-time transmission rate and a segmentation percent root-mean-square difference (PRD) performance is realized through acquiring and processing the ECG signals, and taking the display size of the terminal, the link real-time transmission rate and the PRD performance as self-adaptive control parameters in a transmission process. Based on obtaining a high compression ratio and controllable fidelity, the method acts according to actual circumstances, so that the calculation load for a 3G terminal to reconstruct waveforms is lowered, the terminal resources are saved, the link resources are sufficiently utilized, the transmission delay is shortened, and a further guarantee is provided for realizing real-time monitoring.

Description

technical field [0001] The present invention relates to an electrocardiographic signal transmission method and system, in particular to a wavelet algorithm-based electrocardiographic signal transmission method and system. Background technique [0002] The medical information standards used in traditional remote monitoring and diagnosis systems mainly include XML, UMLS, SNOMED, ​​ICD, DICOM, and HL7. And because domestic hospitals, companies, colleges and research institutions have developed a large number of medical application software based on various medical information standards and applied them in all aspects of medical treatment, but because they do not follow the unified standard, the compatibility of these software is very poor , can not achieve the purpose of fluent exchange of relevant medical information. At the same time, with the improvement of hospital modernization, some large hospitals have formed large-scale hospital information systems, medical image archi...
