摘要
电视电话会议可实现异地会场之间"零距离"沟通和交流,目前已成为国家电网公司开展行政宣贯、调度指挥的有效方式,但是电视电话会议系统容易受传输通道不稳定、设备单点故障的影响造成中断,影响会议正常召开,文章提出一种高可靠性的电视电话会议系统主备设计模式。介绍了电视电话会议系统主备模式的设计方案,并且通过案例介绍了故障应急切换方式,结果证明采用这种模式,可在确保电视电话会议功能需求的基础上,不断加强系统的安全性和可靠性。
Since the teleconference system can achieve ＂zero-distance＂ communication between different places, it has been an efficient mode to carry out administrative implementation, dispatching and command in SGCC. However, its information channel is unstable, even the single point fault may lead to the whole system interruption. This paper proposes a main-standby teleconference system with high reliability; the design scheme is illustrated in detail, and an application case is used to demonstrate fault emergency switching mode. The results show that the proposed scheme can strengthen the safety and reliability of the system.
