摘　　要：合成视景系统(SVS)的完整性是SVS论证中重要的一部分,对SVS完整性的保证可以增加SVS的可信性,而SVS的可用性同样是SVS的重要性质,只有系统的可用性得到保证,系统才会发挥作用。SVS同时保证其完整性与可用性能使其成为一个关键系统而不仅仅是一个建议使用的系统。SVS的实时监控可以有效保证系统的完整性,但是却会降低系统的可用性。所以,本文对SVS的2种性质综合考量,主要先在架构层面对合成视景系统的可用性与完整性进行讨论,提出保证方法,然后以垂直方向的高度数据为例,讨论并提出基于架构层面的告警算法,最终进行模拟仿真,给出验证。本文提出的方法可以有效保证SVS的完整性和可用性,但是对其硬件及架构层面有所要求,同时产生数据资源的冗余。The integrity of SVS system is an important part of SVS, which can increase the credibility of SVS, and the availability of SVS is also an important property of SVS. SVS also ensures that the integrity and availability of the system is a key system and not just a system for use. The real-time monitoring of SVS can effectively guarantee the integrity of the system, but it will reduce the availability of the system. Therefore, this paper is to discuss the availability and integrity of SVS in two kinds of properties, and then puts forward the guarantee method. Then, the paper discusses and puts forward the alarm algorithm based on the architecture level. The method presented in this paper can effectively ensure the integrity and availability of SVS, but it has some requirements on its hardware and architecture, and it has the redundancy of data resources.
