Method and device for reducing power consumption of dynamic electrocardiogram data recording devices

Abstract

The invention relates to a method for reducing power consumption of dynamic electrocardiogram recording devices. The method includes steps of detecting change of currently acquired electrocardiogram data, determining whether the change of the currently acquired electrocardiogram data conforms to laws of P-wave, QRS-wave or T-wave data or not and enabling sampling frequency values of an analog-digital conversion module to be equal to a second sampling frequency if the change of the currently acquired electrocardiogram data conforms to the laws of the P-wave, QRS-wave or T-wave data; enabling sampling frequencies of the analog-digital conversion module to be equal to a first sampling frequency if the change of the currently acquired electrocardiogram data does not conform to the laws of the P-wave, QRS-wave or T-wave data. The analog-digital conversion module can sample analog signals at two different set sampling frequencies at least, so that the analog signals can be converted into digital signals. The sampling frequencies include the first sampling frequency and the second sampling frequency; the second sampling frequency is higher than the first sampling frequency. The invention further relates to a device for implementing the method. The method and the device for reducing the power consumption of the dynamic electrocardiogram data recording devices have the advantages of low cost, good effect and zero missing data.

Description

technical field [0001] The invention relates to medical equipment, more specifically, to a method and device for reducing power consumption of a dynamic electrocardiogram data recording device. Background technique [0002] The current ECG acquisition equipment, especially the dynamic ECG (data) recording box, is a device used to store continuous long-term collection of physiological parameters (ECG data). The current dynamic ECG recording box or dynamic ECG data recording device is usually powered by an alkaline battery or a nickel metal hydride battery, requiring a continuous working time of more than 24 hours on a patient. In addition, in order to reduce the cost of batteries and reduce the environmental pollution caused by discarded batteries, usually one battery needs to collect the data of multiple patients, which requires the power consumption of the recording box to be as low as possible. Since the current dynamic ECG data recording device uses fixed-frequency AD sa...
