The UAV image transmission system adopts appropriate video compression technology 、 Signal processing technology 、 Channel coding technology 、 And modulation and demodulation technology , It is a wireless electronic transmission device that transmits the video captured by the camera on the UAV to the remote receiver in real time in a wireless manner .
WiFi Image transmission is a cost-effective image transmission technology for unmanned aerial vehicles ,WiFi The module can not only transmit the video of aerial camera in real time , It can also transmit data from the ground mobile terminal in real time , Control signals such as mobile phones .
cv5200 It is an excellent two-way wireless communication system . The product is based on 802.11 Wireless communication standards , Adopt self-developed LR-WiFi( Remote WiFi) Private agreements , Have ML,MRC,LDPC,MIMO-OFDM And other advanced wireless technologies .
Why the wireless router WiFi The signal can't travel so far ? At the same frequency , UAV can transmit pictures from a long distance , And the wireless router WiFi The signal is so far away but there is no signal , A large part of the reason is that the power of mobile terminals such as wireless routers and mobile phones is not enough .
CV5200 With ultra long transmission distance , The measured sight distance exceeds 6 km ( Fix 2Mbps,2dB The antenna ).CV5200 Unique LR-WiFi technology , Ensure real-time transmission at this distance .
CV5200 With narrow bandwidth MIMO Wireless communication technology , It has strong anti-interference ability , And support automatic channel selection .
use ML,MRC,MIMO-OFDM And other advanced wireless technologies , Provide reliable 、 Clear wireless signal , It can realize long-distance non sight distance (N-LOS) Mobile wireless communication . In multipath 、 Maintain reliable transmission in the environment of mobile Doppler effect .
UAV image transmission system adopts H.264/H.265 Digital video coding standard , Support AV、 AHD、SDI、HDMI,RJ45、WIFI Multiple communication interface signals are accessed through DSP Do compression coding ,
Usually like Hanhgk-H.265+/Hanhgk-H.264+ Double code compression technology 、 Support multiple code streams 、 Satisfy M2M Equipment supervision function ; Output HD HD1080P Picture quality , Resolution up to 1920*1080( Backwards compatible 1080p、720P、480P And standard definition ).
CV5200 It has the advantages of long transmission distance 、 Networking 、 Strong anti-interference 、 Ultra high sensitivity . Especially suitable for long distance , High rate occasions , Like drones , Security monitoring , Intelligent building , Smart agriculture , Robots, etc . This product adopts SOC Realization , Good performance and cost , And can be pasted and used immediately , Reduce development .
With the continuous development of UAV Technology , There are more and more kinds of unmanned aerial vehicles , More and more mature , Widely used in agriculture 、 Industry 、 meet an emergency 、 Military and many other fields , And play an increasingly important role .
CV5200 The flat architecture design of ad hoc network is adopted , Support one to many networking and mesh Mesh networking . Access image data through Ethernet interface , Meet the requirements of real-time HD video transmission with very low delay .
Wireless ad hoc network is a kind of network that does not depend on the existing basic communication facilities , It can dynamically and quickly build distributed 、 Technology without central network , Long communication distance 、 High transmission rate 、 Rich interfaces and other features .
Wireless ad hoc networks can be temporarily 、 dynamic 、 Quickly build a distributed decentralized autonomous private network , With self-organization , Since the recovery 、 High survivability and many other advantages , Multi hop automatic routing relay , Network topology 、 Rate adaptation, etc , Suitable for UAV cooperative communication networking .
CV5200 No need for complex driver installation . The only thing you need to do is provide power , Connect Ethernet ,USB Interface or serial port can be used , Save the mind and save labour .
CV5200 use WPA2 AES encryption , Safe and reliable , To protect your data from possible network attacks . use LR-WiFi Wireless technology with carefully debugged hardware , With ultra-high sensitivity .
wireless WiFi The network size generally does not exceed 32 Nodes , With the development of Intelligent Collaborative Control Technology , The number of nodes will be more and more ; Communication anti-interference , With spread spectrum 、 frequency hopping 、 Adaptive frequency selection and other anti-interference functions , Improve the adaptability of the communication networking system to the complex electromagnetic environment .
Each node in UAV ad hoc network has the functions of wireless communication and dynamic routing , It can complete the function of traditional point-to-point communication measurement and control , It can also realize the relay and forwarding of the preferred path of data packets , Greatly improve the distance of measurement and control and the scope of operation , And deploy reasonably through nodes , Able to adapt to complex environment , Realize over the horizon communication .
