Mesh ad hoc network system consists of video and audio data information collection, multi-hop ad hoc network link and dispatching command system center, which can quickly form a long-distance dispatching command system integrating air and ground. The wireless link formed by the nodes of the ad hoc network is transmitted back to the air or ground command center to realize the joint communication function of command and dispatch.
Under the background of high-tech information technology, how to make the exercise realize air-ground integration and multi-regional joint training in a long-distance and complex environment? The construction and application of wireless remote communication network is the key factor.
Wang Yun IOT cv5200 is an excellent two-way wireless communication system, which uses multiple channels to send and receive wireless signals, has good anti-multipath and interference effects, and has flexible networking modes such as point-to-point, point-to-multipoint and mesh ad hoc network.
CV5200 wireless long-range WiFi, based on 802. 1 1 wireless communication standard, adopts self-developed LR-WiFi (long-range WiFi) private protocol, and has the characteristics of long transmission distance, networking, strong anti-interference and ultra-high sensitivity of advanced wireless technologies such as ML, MRC, LDPC and MIMO-OFDM, and is suitable for long-distance and high-speed occasions.
In various complex environments, it can be interconnected with the military network to create a networked tactical communication network with "air-ground integration", and comprehensively command and coordinate the front-end nodes according to the command information nodes.
UAV nodes in the air cooperate efficiently with individual soldiers and vehicle-mounted information nodes to realize real-time interaction between front and rear information. Communication and command information, such as situation awareness, intelligence information sharing, real-time consultation with superior instructions, issuance of leadership instructions, task assignment at any time, etc. Which is implemented between the information nodes of the self-organizing network module in each area.
Using the characteristics of mesh wireless ad hoc network, combined with the existing wireless remote WiFi image transmission equipment, individual soldier system, emergency command vehicle communication terminal and other equipment, it can meet the information transmission in various special environments and is widely used in unmanned aerial vehicles, unmanned vehicles, unmanned ships and other equipment.
The application scope of unmanned aerial vehicle (UAV) is expanding, and it is widely used in rescue and disaster relief, forest fire prevention, fire command, power inspection and other fields. High-altitude and long-distance transmission, using CV5200 long-distance WiFi module, can enable commanders to obtain real on-site information at the first time, and at the same time, it has the characteristics of front information collection, on-site command and information mutual transmission, which is more efficient in emergency rescue.
The transmission distance of CV5200 is very long, exceeding 6 kilometers (fixed 2Mbps, 2dB antenna) under the actual line of sight. The unique LR-WiFi technology ensures the real-time transmission of this distance. It adopts narrow bandwidth MIMO wireless communication technology, which has strong anti-interference ability and supports automatic channel selection.
The advanced wireless technologies such as ML, MRC and MIMO-OFDM are adopted to provide reliable and clear wireless signals, which can realize long-distance non-line-of-sight (N-LOS) mobile wireless communication. The flat architecture design of ad hoc network is adopted, and the image data is accessed through Ethernet interface, which meets the requirement of very low delay of real-time high-definition video transmission.
It can meet a variety of wireless long-distance communication requirements such as security patrol of large-scale activities, urban emergency command, emergency rescue command and dispatch, and fire communication command. , widely used in public security, fire protection, electric power, water conservancy, forestry, radio and television, aviation communication and other fields.
Wireless remote WiFi ad hoc network can provide support for emergency control, audio and video multimedia transmission, sensor data transmission, file transmission, location data transmission and other applications. It can provide stable, efficient, mobile and portable wireless long-distance communication transmission solutions for various environments.
