地震应急视频会议系统是应急指挥技术系统的重要组成部分,是开展地震应急处置的重要支撑手段.北京地震应急视频会议系统由传统的硬件视频会议组成,经过多年的运转和使用,硬件设备问题和局限性凸显.云视频会议作为一种新兴视频会议技术,在调配灵活性、兼容性和资源利用率方面有明显优势.文章围绕云视频会议和硬件视频会议系统的融合应用展开研究,实现了远程培训、远程参会、地震应急现场通讯演练、会议监控等多功能应用场景.实践表明,该融合应用是提高地震应急视频会议系统能力的有效手段. 相似文献

Immediately after an earthquake a healthcare system within a city, comprising several hospitals, endures an extraordinary demand. This paper proposes a new methodology to estimate whether the hospital network has enough capacity to withstand the emergency caused by an earthquake. The ability of healthcare facilities and to provide a broad spectrum of emergency services immediately after a seismic event is assessed through a metamodel that assumes waiting time as main response parameter to assess the hospital network performance. The First Aid network of San Francisco subjected to a 7.2 Mw magnitude earthquake has been used as case study. The total number of injuries and their distributions among the six major San Francisco's Emergency Departments have been assessed and compared with their capacity that has been determined using a survey conducted by the medical staff of the hospitals. The numerical results have shown that three of the six considered San Francisco's hospitals cannot provide emergency services to the estimated injured. Two alternatives have been proposed to improve the performance of the network. The first one redistributes existing resources while the second one considers additional resources by designing a new Emergency Department. 相似文献
