【摘要】 特种文献图书的典藏通常需要较为严格的温度、湿度和空气流通条件,还需提供文献储藏的实时影像以备事中监控和事后查验。为此,基于Qt应用程序框架软件,设计并实现了一套适用于图书馆特种文献典藏库远程监测的嵌入式系统。该系统以S3C2440微处理器ARM 9开发板为控制核心,利用DS18B20型数字式温度处理器、HTF3000LF型Sensorway湿度传感器和ZC0301型中芯微摄像头等设备采集典藏库内的温度、湿度及图像信息,经专用的集成信息采集节点处理后,通过网络和控制室内的监控终端相连,实现典藏库环境多因子异常信息监测报警功能,为文献典藏工作提供高效的科学支撑平台。更多还原

【Abstract】 In order to monitor and control the temperature,humidity and air circulation of library’s stack room,providing monitoring real-time image and useful information records,a novel library special book reservation Qt-based monitoring system is introduced in this paper.First,some features of stack room are analyzed and listed,providing detailed scientific parameters in system designing.Second,the construction method of embedded hardware,for example,the S3C2440 ARM9 board,DS18B20 digital temperature processor,HTF3000LF micro-humidity sensor and ZC0301 camera,are described.Finally,all the information collected by these hardware are sent to the monitoring center room via wireless or wire net,implementing a multi-factor abnormal library information environment monitoring and early-warning functions and providing a scientific support platform for book reservation.更多还原
