Based on the ECG monitoring instrument and ECG signal research, design a series of ARM chip based on STM32 as the core of the portable home ECG detection equipment. The device with three electrodes of ECG signal acquisition, due to weak signal acquisition processor cannot directly handle the ECG acquisition circuit, but also on the ECG signal amplification, filtering and level uplift is sent to the ARM processor, the ARM processor on the received analog signals through the built-in AD discretization, and then the analysis and processing of data real time display on the LCD screen, ECG, heart rate and various analytical results, but also can through the USB interface to a detailed analysis of the data transmission to the host computer. Tests prove that, the system has the advantages of simple structure, stable and reliable work, the ECG can get a clear, stable and biological signals can reflect the real ECG features of human body, according to expert system comes with the system, can to the condition estimation, simultaneously has the advantages of simple operation, low price, easy to carry, has certain market promotion value.
