摘　　要：地震预警系统在过去30年里逐渐从科学界的讨论变成了防震减灾的实践。在调研地震预警系统的发展的基础上,梳理了近年来不同国家、不同机构围绕地震预警开展的研究。介绍了采用简易烈度计(MEMS)和智能手机来实现地震预警的一种尝试性方法。在传统分析地震预警系统发展空间范围的基础上,分析预警系统发展时间节点信息,讨论地震预警系统的实践与实时地震学发展之间的关系。The earthquake early warning system（EEWS） has been gradually developed from scientific hypothesis into real disaster prevention practice for the past 30 years. This paper summarizes the worldwide EEWS development and its constructing divergence in different time periods. Moreover, an introduction of the use of MEMS（Microeletro Mechanical Systems） and smartphone by seismologist and engineers as a new means of earthquake early warning is given. Not only the space for EEWS development but also more information about EEWS time nodes is analyzed in this paper. Finally, the relation between EEWS and real-time seismology is discussed.
