Research on Hospital Operating Room Management System Based on PDA Code Scanning Technology

针对现有的医院扫码技术中出现的识别错误率高、扫码时间过长等现象,该研究基于个人数字助理(PDA)设计了一款新型医院手术室扫描系统,其中PDA扫描装置采用PIC16F877A芯片8位微控制器,通过射频识别与蓝牙技术进行无线传输,极大地提高了扫码效率。此外,为了提高图像分析的精度,还采用基于能量驱动采样优化的分类算法(EDS-CA),将经过PDA扫描接收到的医疗数据信息进行恰当的预处理,之后构建函数分类器,并根据EDS-CA减少进程提高图像处理效率。实验结果表明,设计的扫描系统识别条形码平均精度达到了95%,证明PDA扫码具有优良的性能。
