Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
For unpiloted aerocraft system, comprise aerial and ground two large divisions.Aerial parts comprises: unmanned plane, air environment and auxiliary equipment etc., mainly complete aerial mission.Above ground portion comprises: Aerial vehicle position system, flight control system, navigation system and transmitting recovery system, mainly complete the remote control to aircraft, remote measurement and navigation task, and aerial and ground system is risen by data link setup and is closely connected.Inventor is studied based on to the transfer of data of unmanned vehicle and inquires into, transfer of data link during unmanned aerial vehicle station, radio communication, flight are controlled, in hardware circuit, software program, Reliability Measures etc., carry out a large amount of tests, determined the solution of the present invention.
See Fig. 1-6, microwave box radio station of the present utility model module, by information data by digital data transmission to ground station, RTSP real time streaming transport protocol is adopted effectively to transmit multi-medium data by IP network, agreement supports 1080I, and there is the bandwidth of 8,000,000, high-definition image transmission can be realized, and reduce the error rate and improve real-time.The IPnDDL2450 that radio station module adopts Microhard Systems Inc. to produce, the ASC8850AET that CPU then uses grace intelligence Pu semiconductor N XP to produce.Microwave box on unmanned plane is provided with video conversion module, CPU, network interface card, digital radio station module, air environment (video camera) on unmanned plane enters CPU by three interfaces such as HDMI, CVBS interface, YPbPr interfaces after video conversion module, the chip of CPU carries software kit, Information Compression is produced compressed package, is launched by digital radio station module.The input mode of video data has three kinds, and the Data Filename of often kind of input mode is not identical, by detecting the input mode of filename identification data stream.HDMI can transmit harmless HD video content, the audio content after the harmless of 9 passages or compression can be transmitted, make ground station can receive large discharge HD video, the information that unmanned plane collection returns is carried out Visualization, thus provide data more intuitively for Emergency command decision-making, and Real-time Obtaining and display flight parameter, the visualization processing of convenient research and data analysis and data.H.264 be a kind of mode of video compression, content after compression and the communications protocol of ground station are standard rtsp, another CPU is by network interface card and digital radio station model calling, what video compression bag was walked is also this path, when there being data to flow to digital radio station module from CPU by network interface card, digital radio station module is sent to ground receiving equipment by data.When ground station sends displaying video request by rtsp client, namely CPU compresses encoding video signal and is sent to digital radio station module, and video frame rate is 30fps, and video compression bag is by CPU timing access.After the data that the radio station module that the digital radio station module of receiver end receives transmitter terminal is launched, transfer to ground station by USB network card, namely ground station carries out decoding display.
And, microwave box also has aircraft service data interface, connects digital radio station module by data wire, directly beam back ground by digital radio station module.MCU module connects digital radio station module and outside UART interface by UART data wire, and described MCU is for receiving the switching of external command and video input form.
In ground station, relative set digital radio station module, for receiving the multi-medium data launched from unmanned plane microwave box, through the transponder of USB network card and HUB multiport, is transferred to ground station.Transponder through HUB multiport after the data of UART turn USB is transferred to ground station.
Microwave box uses H264 coding, use new-generation digital video compression standard, adopt demixing technology, formally coding and channel isolation are come, the syntactic structure of standard to coded video bit stream and the method to this bit stream decoding define, and support 4X4 and 16,X16 two kinds of intra-frame encoding modes, and be that predicated error is encoded, therefore code efficiency is higher, therefore, can reduce the error rate, improve real-time.
The utility model can complete remote control command, the real-time playback of monitoring message image and display, and the Storage & Display of log, fully meets the observing and controlling demand of unmanned plane.
