Abstract: this paper studies the portable cardio-cerebral electricity amplifier calibration equipment design and realization. For amplitude is 0.05 mV - 5mV skin ecg signals is simulated amplifier, the important link of ecg acquisition system, is also related to the accuracy of ecg acquisition system core. And calibration equipment the function of the one is proced to simulate electrocardiosignal designated waveform, the test the performance of ecg amplifier.
This paper mainly studies the two aspects of content.
First is the calibration equipment, hardware design, with PIC16F785 as the core controller, the whole equipment by section 5 batteries, highlighted equipment portable characteristics. This design get portable cardio-cerebral electricity amplifier calibration equipment, overcome traditional calibration equipment, the above limitations, that is not suitable for use traditional calibration equipment occasions through a simple calibration and makes cardio-cerebral electricity amplifier can compare to accurately use.
Secondly, according to the corresponding hardware circuit design out of software programs. Equipment adopts dial generated code switch to choose the type and parameter, wave combined hardware and software, will all functions focus on a small equipment, manifested the equipment portable characteristics.
This calibration equipment has been put into use. From running the circumstance looks, it can effectively calibration cardio-cerebral electricity amplifiers, to the customer and company has brought remarkable economic and social benefits.
Keywords(关键词): calibration equipment（校准设备）, PIC microcontroller（PIC单片机）, resonant circuit （升压电路）
