摘　　要：EPICS是一个用于开发分布式设备控制程序的软件开发框架,它主要用于控制大型物理实验设备及天文望远镜系统,而RTS2是Linux系统上的一个远程自主望远镜控制系统。实现了EPICS与RTS2的集成,用RTS2负责望远镜观测流程控制,EPICS用于成像设备控制,使用EPICS的成像控制软件Area Detector完成了Andor相机的控制,并完成了RTS2和EPICS融合的命令状态接口,从而让RTS2能够兼容EPICS组件。成功用RTS2和EPICS实现了Andor相机的控制,并很好地集成到RTS2的流程控制中。The Experimental Physics and Industrial Control System （EPICS） is a software development framework for distributed control systems to operate large experimental equipments. It is also used for developing control systems of astronomical equipments such as telescopes and CCD cameras. The RTS2 is a remote-observatory control （software） system working under a Linux environment. In this paper we present the design and implementation of an imaging control software system using the RTS2 and EPICS. In our control system the RTS2 is used to control observation processes and the EPICS is used to control imaging devices. An EPICS toolkit named AreaDetector provides the functions for imaging-device control and data acquisition. In order to make the EPICS/IOC （Input/Output Controller） and the RTS2 work together in our system, we have designed an interface between the AreaDetector and RTS2. The interface is for mapping commands or statuses. Our test shows that the AreaDetector is suitable for control of imaging devices, and the EPICS/IOC can be integrated with the RTS2 system due to the extension with the interface of the RTS2. Our system is also successful in controlling an Andor camera. Overall, our imaging control software designed based on the RTS2 and EPICS is effective.
