摘要
针对短波低速通信条件下船舶远程维修指导效率低下的问题,提出了一种新的基于PDF动态标注技术的远程维修指导信息交互手段。基于Acrobat SDK实现了PDF文档所见即所得方式的动态标注,其中重点解决了PDF文档动态加载、基于Windows钩子技术的PDF文档鼠标响应处理、PDF标注动态添加中的坐标空间变换以及PDF标注文本的动态修改等问题。实际应用表明,通过应用PDF动态标注技术,实现了窄带低速通信条件下的所见即所得的维修信息描述,为无视频通信辅助条件下的高效远程维修指导提供了一种可行手段。
Low efficiency is a serious problem faced in remote repair system based on low data rate shortwave communication. A novel remote instruction interactive technique based on dynamic PDF annotation is proposed in this paper. Key processes including dynamic PDF document loading, mouse action responding of PDF document based on Windows hook technology, coordinate transforming in dynamically inserting or modifying PDF annotation text are introduced in detail. Actual application shows that dynamic PDF annotation makes ＂What You See Is What You Get （WYSIWYG）＂ description of repair information based on narrow-band low data rate communication system possible and it is a practical method for efficient remote repair instruction even without the aid of video communication.
