Paper Abstract

For astronomical observations, there are many kinds of CCD cameras for different scientific purposes. Sometimes, this even happens in one telescope. Traditionally, a CCD camera has an individual image grabber, data process unit, and corresponding control computer. Consequently, this brings some inconvenience and problems not only to the system management but also to the updating of the system. This paper presents a resolution to this problem for the Multi-Channel Solar Telescope (MCST). All CCD cameras are connected in an Ethernet through an Ethernet interface. A server is needed to send commands to all cameras and transfer data through TCP/IP. Each CCD camera has an embedded system to control the camera, receive commands from the server and signals from the camera, process, and store the data. This paper describes the design of an Ethernet controlled camera. The camera is PULNIX TM1010, which is controlled by an Altera embedded system by Cyclone EP1C20F400C7 FPGA, which embedded with a Nios processor.
