抚仙湖太阳观测和研究基地知识库

CMOS相机是一种重要的固体成像设备。随着科研级CMOS相机的性能不断提高,现在广泛应用于科研领域。抚仙湖的新真空太阳望远镜(NewVacuum Solar Telescope,NVST)的成像设备也在使用CMOS相机。因此建立一个天文CMOS相机测试系统，对于新购CMOS相机的验收以及现有CMOS相机的定期检测和维护有十分重要的意义。本文介绍了天文CMOS相机测试平台的硬件组成，并针对实际测试中对设备控制的需求，以及利用控制器对相应的设备直接控制，提出了基于TCP/IP协议以及串口通信的设计方案，利用C#编程语言设计了一套多线程并行的控制系统软件，实现各设备在局域网内的远程并行控制。通过对设备的运行测试，结果表明此系统能良好的控制各设备的正常运行，满足测试系统集成控制的需求。

CMOS cameras are important solid-state imaging devices. As the performance of scientific CMOS cameras continues to improve, it is now widely used in scientific research. The imaging devices of the New Vacuum Solar Telescope (NVST) are also using CMOS cameras. Therefore, the establishment of an astronomical CMOS camera test system is of great significance for the acceptance of new CMOS cameras and has a high value for the regular detection and maintenance of existing CMOS cameras. This paper describes the hardware components of the astronomical CMOS camera test platform. Taking advantage of the direct control of the corresponding equipment by the controller, a design scheme based on TCP/IP protocol and serial communication is proposed to meet the requirement of equipment control in actual test. A multithreaded parallel control system is designed by using C# programming language to realize remote parallel control to each device in the LAN. Through the operation test of the equipment, the results show that the system can well control each equipment to operate and meet the requirement of the integrated control of the test system.
