ECG acquisition platform

Abstract

The invention relates to an ECG (electrocardiogram) acquisition platform which comprises an acquisition chip, an ARM core microprocessor, an FPGA (field programmable gate array) chip and an upper computer, wherein the acquisition chip obtains ECG original data, and performs analog-digital conversion; the ARM core microprocessor obtains the ECG data after analog-digital conversion, and performs ECG data integration to obtain integrated data; the FPGA chip receives the integrated data, and processes the integrated data into disposal data with proper bit width; the ARM core microprocessor is further used for performing data distribution via a channel identification bit, and sending the distributed disposal data; the upper computer respectively performs ECG display on the distributed disposal data via a predetermined data transmission protocol. The ECG acquisition platform provided by the invention realizes integral control of the system through the ARM core microprocessor and realizes digital signal processing through the FPGA chip, so as to accelerate the system development process, and reduce the replacement cost of a chip with a single function.

Description

technical field [0001] The invention belongs to the field of medical care and medical care, and in particular relates to an electrocardiogram collection platform.
