Research and Implementation of Transient Quick Response and Automatic Observation System

天文瞬变源后随观测对于瞬变源证认具有重要的意义。瞬变源发生的偶然性和光变的快速性要求后随观测系统具有快速自动响应的能力。介绍了基于Python开发的天文瞬变源快速自动响应观测系统的研究和实现,核心是基于Django架构实现数据库交互与模块调度功能。系统有基于VOEvent的警报消息传递、网络端状态监控与交互平台、数据自动处理和结果自动反馈以及望远镜控制接口等主要功能。通过在北京的中法天文卫星科学中心和兴隆观测基地之间的消息数据传递和实际触发观测测试表明,系统能满足中法天文卫星项目地基观测系统瞬变源后随自动响应观测的基本要求,同时系统还具有良好的可移植性,适用于其他类似的自动响应观测系统。

Follow-up observation of astronomical transient sources is important for the identification of the transient source. The random nature of the transient sources and the speed of change of brightness require the follow-up observing system to react quickly and automatically. In this paper we describe our study and implementation of the Transient Quick Response and Automatic Observation System based on Python. At the core is the functional realization of database-interface and module-scheduling based on Django architecture. Main functions of this system include alert message transmission using VOEvent, a web-based status monitoring and interface automatic data processing and reporting, and telescope control interfaces. Tested with data transfer between the SVOM Chinese Science Center located in Beijing and Xinglong Observation Station, and actual triggered observation, the system has met the basic automatic transient follow-up observation requirements of the SVOM project. At the same time, the system can be used for other similar automatic response observation thanks to its portability.
