摘　　要：引力波的直接探测开启了引力波天文学的新纪元.引力波事件高能电磁对应体的探测研究作为研究引力波源和基础物理规律的重要手段已成为天文研究领域的热点.随着引力波探测器的升级,引力波样本数急剧扩大,对其高能电磁对应体的探测需求日益紧迫.引力波暴高能电磁对应体全天监测器(GECAM)卫星是针对引力波高能电磁对应体探测研究所蕴含着的重大发现机遇而提出的全天监测器项目.GECAM卫星科学应用系统的主要功能包括保障卫星有效载荷的科学运行,实现科学数据的生产、存储、处理、标定、发布与分析,以及为科学用户提供技术支持和服务等.本文以引力波事件高能电磁对应体的探索研究为出发点,介绍GECAM科学应用系统针对引力波事件高能电磁对应体创新性的监测方法设计,即GECAM科学应用系统的方案设计.设计涵盖系统架构、接口控制、主要技术流程、功能组成及软件规划设计等.GECAM卫星计划于2020年底发射,届时科学应用系统将具备执行运行任务的能力,为卫星的在轨科学运行及科学研究提供支持和保障.The direct detection of gravitational waves has started a new era of gravitational wave astronomy. As an important method for studying the counterparts of gravitational waves, the observation and search of the multi-wavelength radiation of the electromagnetic counterpart of gravitational waves has become the research focus in the field of astronomy. With the advancement of gravitational wave detectors, the number of gravitational wave samples has dramatically increased and the detection of gravitational wave electromagnetic counterparts has become very promising. The Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor(GECAM) satellite is a full-sky monitoring telescope designed for detecting high-energy electromagnetic counterparts of gravitational wave events. The main reason for designing a scientific application system of GECAM satellites, which is proposed and designed with an emphasis on discovery, is to ensure the scientific operation of the payload of satellites and achieve the production, storage, processing,calibration, release, and analysis of scientific data. It is also designed to provide technical support and services to scientific users. Based on the exploration and research of the gravitational wave electromagnetic counterpart, this article introduces an innovative monitoring method design of the GECAM scientific application system for the gravitational electromagnetic counterpart, namely, the scheme design of the GECAM scientific application system. The design covers system architecture, interface control, main technical processes, functional composition, and software planning and design. The GECAM satellite is scheduled for launch by the end of 2020. By then, the scientific application system will be able to support the satellite’s in-orbit scientific operation and research.
