Abstract

The invention discloses an electrocardiosignal collector which comprises an electrocardiographic lead, a voltage conversion device, an electrocardio collection chip, an audio frequency modulating unit and an audio frequency interface. The electrocardiographic lead is connected with the electrocardio collection chip. Electrocardio signals are detected to be input into the electrocardio collection chip. The electrocardio collection chip conducts analog front end amplification on the input electrocardio signals, low-frequency simulation signals are formed to be output to the audio frequency modulating unit. The audio frequency modulating unit conducts high-frequency modulating on the low-frequency simulation signals and outputs the low-frequency simulation signals. An electrocardiosignal collector is connected with the audio frequency input end of an external device through the audio frequency interface. The voltage conversion device is connected with the audio frequency interface, and voltage is generated according to input of the external device to supply power to the electrocardiosignal collector. The audio frequency modulating unit is connected with the audio frequency interface to output the modulated electrocardio simulation signals to the external device. According to the electrocardiosignal collector, the audio part of an intelligent terminal is fully utilized, collection and transmission of electrocardiosignals are completed, the hardware complexity of the collector is minimized, and the cost of the collector is lowered effectively.

Description

technical field [0001] The invention relates to the field of electrocardiogram signal acquisition and processing, in particular to an electrocardiogram signal collector, an electrocardiogram processing system and a processing method thereof. Background technique [0002] As a non-invasive and simple detection method, electrocardiogram plays an important role in the early screening of heart diseases. In recent years, with the development of Internet health technology, many miniature ECG signal acquisition and analysis systems for individuals and families have emerged. However, the terminals used in these systems all need terminals with independent power supply, and all need an independent MCU or AD sampling module to realize the collection, and then communicate with intelligent mobile terminals (such as smart phones, tablets, etc.) through Bluetooth, USB or other data communication methods. Realize data transmission. At present, for the domestic patented technical solutions...
