For border patrol and hydrological survey, select the Navigator amphibious vehicle

1. Video conference function
(1) Video system:
1. Images around the vehicle can be collected by the front and rear pan-tilt cameras and transmitted to the in-vehicle video switching equipment (matrix);
2. The in-vehicle dome camera collects images inside the vehicle and transmits them to the in-vehicle video switching equipment (matrix);
3. Drones can collect video from distant or dangerous areas and transmit it back to the command vehicle;
4. The matrix can switch any local image or video image transmitted via video conference over the network to the in-vehicle display, or switch any local image to the video conference equipment and transmit it to the remote command post via the network.
(2) Audio system:
1. Audio signals collected by the in-vehicle microphone, remote audio signals collected by the individual soldier backpack device, or audio signals transmitted via the video conference terminal over the network can be processed by the in-vehicle audio switching equipment (matrix) to amplify any audio signal locally through the in-vehicle speakers or external speakers;
2. The audio signal collected locally (on the command vehicle) can be transmitted to the remote command post via the video conference terminal through the in-vehicle audio switching equipment (matrix). The above audio and video systems form the video conference system.
The video conference system of the command vehicle can transmit the 360-degree real-time situation of the rescue site to the internal display of the vehicle, and also transmit real-time signals from multiple sources such as drones and command offices.
2. Radio system:
The command vehicle is equipped with one 350M VHF mobile radio, which can form a network communication with handheld radios or mobile radios of other command vehicles.
3. 4G public network system:
The network system composed of 4G wireless routers and switches can realize data transmission through the public network.
4. Telephone system:
The command vehicle is equipped with one maritime satellite phone, which can directly make telephone calls in areas not covered by public network base stations;
It is also equipped with one voice network gateway and telephone to realize communication in areas accessible to 4G or wired public networks;
5. Individual soldier communication system:
The command vehicle is equipped with a set of individual soldier system, including individual soldier transceiver and individual soldier backpack device. At the rescue site, video and audio signals are collected by the individual soldier backpack device and transmitted to the command vehicle via wireless means; The in-vehicle audio signals can also be transmitted to the individual soldier backpack device for on-site remote command.
6. Centralized control subsystem:
Operations such as the rotation, zoom and focus adjustment of the pan-tilt cameras, as well as the input and output switching of audio and video equipment can be carried out through handheld iPads, network protocol converters, wireless routers and customized central control software.
7. Satellite communication subsystem:
The satellite communication subsystem includes on-board stations and ground stations, which can realize communication services when the public network is paralyzed in major disasters. When the public network is down, the command vehicle can flexibly establish a network connection with the ground station, and cooperate with the video conference system to realize functions such as command and remote conferences.
