Wireless Emergency Communication Systems Support Rescue Efforts
In emergency rescue operations, disaster situations are commands. When all rescue forces rapidly assemble, they carry out tasks according to their respective responsibilities - conducting rescue operations, ensuring communication, and providing logistical support. Forward assault teams and communication support teams in each operational zone select and carry wireless video transmission equipment such as portable devices, surveillance spheres, 4G vehicle-mounted systems, satellite vehicle-mounted systems, and MESH self-organizing network devices into the disaster area based on the on-site conditions. These are used for personnel search, live image and video recording, and comprehensive emergency rescue.
A multi-network integrated wireless emergency communication system is an effective communication solution. Depending on the environmental conditions, the appropriate communication terminal is selected to complete the transmission of wireless video data. In areas without public network signals, front-line personnel carry MESH self-organizing network devices to establish link networks. The self-organizing network nodes at the rear integrate with 4G or 5G vehicle-mounted systems, surveillance spheres, and other terminals for communication. Satellite communication can also be chosen to connect with the command center for data transmission. The command center uses a dispatch system to manage comprehensive audio and video coordination.
Mesh Self-Organizing Networks
Mesh self-organizing networks represent a novel wireless network technology entirely different from traditional wireless networks. In a Mesh network, each node does not exist as an isolated wireless repeater; instead, they interconnect with one another, meaning each node is connected to several pathways, forming an integrated network. The advantage of this is that if a particular path is blocked or unresponsive, the node can autonomously select another route for data transmission. This ensures network access is not disrupted by the failure of any single node, making it highly reliable. Below, let’s explore the functional applications of Mesh self-organizing networks.
Video Command
Video capture devices for each combat team member and drone connect to wireless self-organizing network nodes via Ethernet ports or Wi-Fi. Through this system, real-time two-way interconnection is achieved with the audio and video dispatch platform in the command vehicle and off-vehicle commanders. The command vehicle and off-vehicle commanders can retrieve single or multiple streams of video footage transmitted by team members at any time via the audio and video dispatch platform or handheld command terminals, enabling real-time command decision-making.
Voice Communication
VOIP communication devices for each combat team member connect to wireless self-organizing network nodes via Ethernet ports or Wi-Fi. Through this system, real-time two-way interconnection is achieved with the audio and video dispatch platform in the command vehicle and off-vehicle commanders. The command vehicle and off-vehicle commanders can initiate individual, group, or broadcast voice calls to one or multiple team members at any time via the audio and video dispatch platform or handheld command terminals, enabling real-time two-way voice communication between individual team members, off-vehicle commanders, and other team members.
Location Information Sharing
Each wireless self-organizing network system, after obtaining its position via BeiDou/GPS, can transmit this location information through the wireless self-organizing network system to the command information terminals in the command vehicle or with off-vehicle commanders. This enables commanders inside or outside the vehicle to track the real-time positions of every team member and drone. Each wireless self-organizing network node can utilize GPS/BeiDou for positioning and share this location information by transmitting it to other nodes within the wireless self-organizing network system.
Applications
Wireless communication systems are widely used in various fixed and mobile communication systems for public security, armed police, firefighting, safe city projects, construction sites, forest fire prevention, oil field, mining areas, hydrological monitoring, rail transit, emergency deployment, border and coastal patrol inspections, and more.
