Embodiment 1

[0093] Embodiment 1, ECG signal acquisition device

[0094] Image 6 Shown is an ECG signal acquisition device, which includes a microprocessor, a signal detection module, an LCD display module, a Bluetooth module and a button module respectively connected to the microprocessor, and the output end of the signal detection module is connected to the microprocessor. I / O port, the microprocessor communicates with the LCD display module and the Bluetooth module through the I / O port respectively (see Figure 11 ) is connected to the button module.

[0095] The signal detection module includes a preamplifier circuit, a low-pass filter and an amplifier circuit connected in sequence (see Figure 8 ) and a band-stop filter circuit (see Figure 9 ), the output end of the band-stop filter circuit is connected with the I / O port of the microprocessor.

[0096] The band-stop filter circuit is a 50HZ band-stop filter circuit.

[0097] The keys may include up and down keys, mode keys, c...

Embodiment 2

[0100] The process of the method for the identification of the ECG signal proposed by the present invention includes two parts, such as figure 1 , 2 shown.

[0101] The first part is registration. First, collect the ECG signal (30 seconds-60 seconds) through the self-designed ECG signal acquisition device in Example 1, upload it to the computer through Bluetooth, and process the ECG signal, including R wave detection, R point alignment , draw color overlays, define boundaries, and define individual templates.

[0102] The second part is detection. First, collect the ECG signal (5 seconds) through the self-designed ECG signal acquisition device in Example 1, upload it to the computer through Bluetooth, and process the ECG signal, including R wave detection, ECG judgment, and output. Judgment results, to achieve the purpose of identification.

Abstract

A method of using electrocardiosignals for identity recognition includes two parts: the first part, registration: collecting electrocardiosignals (30-60 seconds) through an electrocardiosignal collecting device, uploading the electrocardiosignals to a computer through a Bluetooth, and subjecting the electrocardiosignals to processing including R-wave detection, R-point aligning, color overlay chart drawing, boundary determining and personal template determining; and the second part, detection: collecting electrocardiosignals (5 seconds) through the electrocardiosignal collecting device, updating the electrocardiosignals to the computer through the Bluetooth, and subjecting the electrocardiosignals to processing including R-wave detection, electrocardiogram judging, judging result outputting and realizing identity recognition. By the method, identity recognition based on electrocardiograms is realized, convenience in collecting of electrocardiosignals is realized, and wireless transmission of the electrocardiosignals is realized.

Description

technical field [0001] The invention belongs to the technical field of biological information identification, in particular to an electrocardiogram-based identification method. Background technique [0002] In the field of information security, the discovery of new biological information features will inevitably attract widespread attention from multiple disciplines and fields, its integration with other existing biological information, and the generalization and application of multi-biological information identification system models. , all of which provide the possibility of realizing higher security level domain requirements. ECG (electrocardiographic signal) is the biological information that meets this characteristic. [0003] Because ECG and the heart have disease characteristics, the reliability of ECG in diagnosing heart disease has been continuously improved in the century since its birth, and it has become an important method for heart disease diagnosis. In the p...
