摘　　要：提出了在基于嵌入式Linux的可视嗅觉系统中使用嵌入式数据库SQLite进行测试数据管理的方案。一方面,通过SQLite与GUI(图形用户接口)开发工具wxWidgets结合,在PC上开发了图形化的数据库操作工具,用于实现数据库的创建和删改等操作;另一方面用户程序可通过SQLite访问数据库,并采用最近邻算法来实现对待测分析气体的识别。仿真实验结果表明,在要求数据库规模不大的情况下,系统能够对库存分析气体作出快速而准确的识别,从而验证了SQLite应用于系统图像数据管理的有效性。A scheme that uses embedded database SQLite to manage the tested image data in smell-seeing system based on embedded Linux is presented.On one hand,SQLite provides API that is combined with the GUI development tool wxWidgets for the development of a graphic database tool to operate the database;on the other hand,SQLite provides API to the user application program to access the database,and the system recognizes the current analyte using nearest neighbor algorithm.Simulation experiment results show that the system can recognize the analytes contained in the database quickly and accurately on the condition that the database of the system is miniature,which verifies that the application of SQLite in system image data management is effective and reliable.
