Wireless ad hoc network communication solution 01

Background Description

Our country has a complex and challenging terrain, and is constantly subjected to natural disasters such as typhoons, floods, and earthquakes. Natural disasters have extremely strong destructive power, and the communication facilities, transportation facilities, and power facilities in the affected areas are prone to being damaged. Once destroyed, the public network will not be connected, seriously affecting people's normal lives. At the same time, it also affects the normal rescue work of the command personnel, resulting in low rescue efficiency and problems such as rescue blind areas.

01. Signal Interruption

Natural disasters, especially earthquakes, floods, and typhoons, often cause severe damage to communication infrastructure. Communication base stations, transmission lines, switches and other equipment may be damaged or fail, resulting in the inability to transmit signals normally. Signal interruption will directly affect the communication capabilities of the affected areas, making internal communication within the disaster area and communication with the outside world difficult, or even completely interrupted. This not only affects the daily communication needs of the disaster victims, but also seriously affects key links such as rescue command and information transmission.

02. Road Damage

Natural disasters such as earthquakes and floods often cause road collapses, bridge fractures, mudslides, etc., resulting in road damage or traffic disruptions. Road damage will seriously hinder the entry of rescue personnel and materials, increasing the difficulty and cost of rescue. At the same time, it also affects the transportation and logistics within the disaster area, making it difficult for disaster victims to obtain necessary rescue supplies.

03. Power Interruption

Power facilities are prone to damage in natural disasters, such as power grids, substations, power stations, etc., which may be damaged or fail due to earthquakes, floods, etc. Power interruption will directly affect the operation of important equipment such as lighting, heating, and medical care in the disaster area, causing great inconvenience to the lives of disaster victims. At the same time, it also affects the normal use of rescue equipment, reducing rescue efficiency.

04. Communication Difficulties

Communication difficulties will seriously affect the information transmission and rescue command in the disaster area, making rescue work difficult to be carried out effectively. At the same time, it also increases the psychological

pressure and panic of disaster victims. 02

Solution

Due to the uncertainty and urgency of emergencies, the time and location of the incident cannot be predicted in advance, and the existing communication network cannot ensure the existing emergency needs. The command center and relevant departments may not be able to promptly and fully understand the relevant situation and issue instructions in a timely manner. The difficulty of command and coordination is high, so the construction of the power emergency communication system urgently needs to be improved and enhanced. Therefore, a complete power emergency communication system needs to be established to support on-site video transmission and voice communication, in order to ensure that different departments can be mobilized in the shortest time, cooperate in combat, and make orderly, rapid and efficient responses to emergencies.

Visual Command

This solution can quickly establish a wireless broadband network at the emergency site, realize visual and video-based command and dispatch, and can be cascaded with the satellite network to achieve cross-level coordinated command, meeting the need for the on-site rescue teams and leaders at all levels to view the real-time video of the site simultaneously, initiate video consultation and command dispatch at the first time, and improving the real-time性和 accuracy of emergency response and handling. 

Rapid Network Setup

In the event of a major natural disaster or accident, emergency personnel rush to the scene urgently. Frontline personnel can use backpack/handheld devices to quickly set up a mesh network on-site. At the same time, multiple collection terminals and surveillance balls can be connected to the mesh self-organizing network. 3

Expand coverage

The high-altitude base station of the tethered unmanned aircraft can expand the transmission link of the mesh self-organizing network, with a coverage distance of over 10 kilometers. The high-altitude base station acts as a relay link to transmit the on-site mesh signals to the mobile command center.

Real-time scheduling

The mobile command center can schedule the audio and video signals of the front-end personnel in real time. Through the satellite link, the on-site images are pushed to the rear command center. This enables rapid mobile command and efficient communication and coordination.
