Time：2022-08-20

    The command and dispatching system and video conference system construction service project of Yantai Haiyang Emergency Command Center is composed of self-organized network individual equipment, portable emergency command center, 4G emergency control equipment and 4G intelligent terminal equipment.


    一、Within the coverage range of public network signals, 4G emergency control equipment and 4G intelligent terminal equipment can upload the collected audio and video information to the command center in real time, and the command center can conduct real-time two-way voice and video conference with the terminal equipment.
    二、In the area without public network signaling, microwave private network communication equipment is used for extended coverage. Within the signal range of the portable emergency command center equipment, video, voice and data transmission can be realized, and remote transmission of wireless images can be realized. The advantages of the system are as follows:
        1、Bidirectional video transmission
        2、Long transmission distance, strong diffraction/penetration ability
        3、Stable transmission of audio and video signals under high-speed mobile and multipath interference
        4、Support hot plug, automatic identification of audio and video sources, no need to restart
