电平

The hardware design mainly includes signal detect circuit , electrical level translation circuit , microcontroller interface circuit , data communication circuit and so on
在硬件电路设计方面完成了信号检测电路、电平平移电路、单片机接口电路以及数据通信等电路的设计。
Design ecg collecting module ， which includes preamplifier ， high pass filter , 50hz notch filter , skin electricity filter , low pass filter , electrical level rising and primary amplifier , adc and mcu , real time clock
设计心电采集模块，包括心电前置放大、高通滤波、工频陷波、肌电滤波、低通滤波、电平抬升和主放大、 a / d转换和单片机，实时时钟。
Because the signal which serial interface output of mcu is ttl logic level , it is essential to transform ttl electrical level to rs - 232 electrical level when the mcu is communicated with pc . in this paper the universal rs232 / 485 electrical level converting circuit board is designed . it can realize data transmission by the two communication level manner
因为单片机的串行输出接口输出的电信号是ttl电平，这样在和上位机通信时需要通过转换电路对其电平进行转换，所以在本课题中设计了通用的rs - 232 485电平转换电路板，可以实现两种不同电平的数据传输，通过最后的实验验证，该电路板能实现所要求的功能，传输信号可靠准确。
