摘　　要：目的左心室磁悬浮辅助装置是治疗心力衰竭的有效工具,其中转子是辅助装置的核心部件,其运行状况及稳定性是评价辅助装置的重要指标,因此加快转子运行状况测量系统的设计和降低开发成本也就至关重要。方法本文采用现代电子设计自动化(electronic design automation,EDA)技术和计算机虚拟仿真技术辅助本系统的设计。在系统中采用ATmega16单片机作为主控制器,采用自带的AD实现多路数据的采集,且把采集到的数据实现实时多路显示,并通过LCD显示的图形判断转子运行情况的好坏。结果设计了一套基于AVR单片机的转子稳定性测量系统。结论该测量系统能够实时监测转子的运行情况。Objective Left ventricular assist device is an effective tool for the treatment of heart failure in magnetic levitation. The rotor is the core component of the auxiliary device and the running status and stability are two of the important indicators. It is important to speed up the design of the measurement system for the rotor and reduce development costs. Methods We design this system by using modern EDA technology and virtual simulation technology. ATmega16 microcontroller as the main controller in the system, multi-channel data acquisition is realized by using own AD, and the data collected can be real-time and multi-channel displayed. Through the LCD display graphics we can determine the status of the rotor. Results A measurement system for rotor stability based on AVR microeontroller is designed. Conclusions The system can real-time monitor the running conditions of the rotor.
