Embodiment Construction

[0080] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0081] The embodiment of the present invention discloses a processing method for an overcomplete dictionary, please refer to the attached figure 1 , the method specifically includes the following steps:

[0082] S101: Receive compressed ECG data and original ECG data of the user, wherein the compressed ECG data is ECG data obtained by compressing the original ECG data;

[0083] Specifically, when the medical personnel use the terminal equipment held by them t...

Abstract

The invention provides a processing method, device and system for an overcomplete dictionary. The method comprises the steps that first reconfiguration electrocardio data calculated by using a currentovercomplete dictionary and a reconfiguration algorithm and received original electrocardio data are subjected to error value calculation; whether or not a current preset overcomplete dictionary still accords with a change rule of recent electrocardio data of a user can be known; if it is judged that an error value of the two kinds of data exceeds a preset error value, the latest original electrocardio data of the user is used for dictionary training, a replacement dictionary is generated and used for replacing a previous preset overcomplete dictionary, the replacement dictionary is reconfigured when compression electrocardio data of the user is received next time, the original electrocardio data of the user is precisely restored accordingly, and the occurrence probability of diagnostic errors of doctors is effectively lowered.

Description

technical field [0001] The present invention relates to the technical field of biomedical engineering, and more specifically, relates to a processing method, device and system for an overcomplete dictionary. Background technique [0002] In recent years, as the incidence of heart diseases has increased year by year, the traditional face-to-face diagnosis mode between patients and medical staff can no longer meet people's needs for health. Therefore, wireless sensor networks are used to realize remote monitoring of patients' ECG data. Monitoring has gradually become the preferred means of ECG monitoring. [0003] At present, by compressing the collected patient's ECG data and then transmitting it to the terminal equipment held by the medical staff through the wireless sensor network, the data volume of the ECG data to be transmitted can be reduced to avoid delay and packet loss Afterwards, the terminal equipment held by the medical staff uses its built-in over-complete dicti...
