RTS2作为远程望远镜控制的开源框架，在天文自主观测领域得到了广泛的应用，在观测仪器中， CCD是天文望远镜系统中一个必不可少的组成部分。在实际工作环境中，部分CCD在Linux操作系统下缺乏支持，致使该设备无法在RTS2框架中协同工作，在无替代CCD的情况下导致整个望远镜系统无法正常使用。借助Windows下的DirectShow技术对视频设备的支持，在Linux与Windows异构操作系统间利用Socket 通信技术建立访问控制桥梁，从而扩展出一种新的CCD类型。通过测试， RTS2能借助该设备控制Windows下的CCD，并实时获取图像，研究取得了一定的成果：（1）使用DirectShow技术控制和访问Windows驱动模型（Windows Driver Model， WDM）的所有CCD获得一种通用的CCD访问方式；（2）借助Socket通信进行延伸对RTS2框架下的其他类型设备在异构操作系统下扩展具有参考意义。

As an open-source framework for remote telescope control with a Linux operating system, the RTS2 has been widely used in automatic observation using astronomical telescopes.Among various instruments a CCD is an essential part of an astronomical telescope system.However, there is a lack of technical support for operating CCD devices of a number of types under practical Linux environments, causing such a CCD device not functioning in the RTS2 framework.Without a replacement CCD the entire telescope system will be useless.Based on the function of the DirectShow technology in supporting video equipments under a WINDOWS operating system, we propose a method to use a Socket to establish communications between a Linux environment and a WINDOWS environment, so as to extend operations of a CCD into the LINUX environment.We have found from our test that a CCD device working under the WINDOWS but with its operations extended using our method can be controlled in the RTS2 to obtain real-time images.Our research has certain achievements:1) A commonly applicable method using the DirectShow is realized to access and control any CCD supported by a WINDOWS Driver Model.2) The extension of CCD operations within the RTS2 framework through Socket communication provides rather valuable reference for incorporating equipments of other types in a system with heterogeneous operating systems.
