摘要 介绍了一种基于模拟移动通讯1.8 GH z射频信号的细胞实验辐照系统的计算机控制系统设计和实现。该系统可以根据用户需求,模拟多种手机工作方式进行不同电磁波能量吸收比率(Spec ific absorption rate,SAR)值下的细胞微波辐照实验,从而进行移动通讯射频电磁辐射对细胞基因表达影响机制的研究。系统硬件部分包括多组射频设备、波导谐振腔及控制计算机;软件部分介绍了整个系统的监控及控制算法的实现与优化处理。本系统已经成功应用于浙江大学医学院“移动通讯射频电磁辐射对细胞基因表达影响机制的研究”。 This paper presents the design and development of a set of microwave exposure system based on 1.8GHz mobile RF signal. This system can work on several modulation types to do microwave exposure experiment under different specific absorption rate (SAR) and prepare the way for researches in the effect exerted by the electromagnetic signal of mobile on human health. The hardware is made up of several RF instruments, waveguide and computer, and the software introduces the accomplishment of the control system and the algorithm of control.
