摘　　要：在微型诊疗装置的应用中,微型装置的体内空间定位非常重要,而定位数据的采集是其中的关键环节。根据体内微型装置磁定位实验研究系统数据采集的特点,设计出一种基于单片机和串口通信的计算机接口用于定位数据的收集、传输等。实验表明,该接口电路能满足实时采集数据的需要,数据传输可靠,在计算机中可以进行现场采集数据的实时保存及其他后处理,能满足实验系统的要求。The location of the micro medical device inside the human body is pivotal in the diagnosis and treatment process, and the positional signal detecting has close relationship with the outcome of this process. This paper provides a method of the computer interface based on the single chip and serial port communication for the magnetic positioning experiment system. This interface system can be used for data acquisition, transmission, calculation and saving. The experiment has proved that, this interface meets the need of the real-time data collection, provides credible data transferring and saving, and satisfies the demands of the experiment very well.
