Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection range of the present utility model is not limited to the following stated.
As shown in Figure 1, based on the real-time return system of unmanned plane line walking HD video of relaying, comprise grounded receiving station, multilevel relay equipment and remote patrol unmanned machine, the described unmanned plane that cruises at a distance is connected with multilevel relay equipment, grounded receiving station respectively by wireless telecommunications; Collect multilevel relay equipment and be connected with grounded receiving station by wireless telecommunications; Described remote patrol unmanned machine comprises HD video video camera and H.264 coding/decoding module; Described remote patrol unmanned machine, every one-level of multilevel relay equipment and grounded receiving station include COFDM modulation /demodulation module.
The progression of described multilevel relay equipment is greater than or equal to zero.
Described multilevel relay equipment is relaying unmanned plane or relay station.
Described grounded receiving station can receive the data sent from self nearest one-level (first order) trunking, and can receive the data sent when remote patrol unmanned machine does not exceed grounded receiving station receiving range.
Embodiment one:
When the scope of patrolling and examining of patrol unmanned machine is within 20 kilometers, do not need trunking, the progression of multilevel relay equipment is 0; Above remote patrol unmanned machine, Real-time Transport Protocol is used after the video information compression using coding module that high-definition camera is collected, send to modulation /demodulation module by the mode of multicast, through modulation /demodulation module with frequency A modulation, send with frequency A after amplification; Modulation /demodulation module above grounded receiving station can connect the video information of remote patrol unmanned machine by frequency of utilization A, watches process to give receiving station staff after frequency A demodulation.
Embodiment two:
When the scope of patrolling and examining of patrol unmanned machine is in 35 kilometers, due to remote patrol unmanned machine overhead receiving station's distance more than 20 kilometers after, grounded receiving station can not receive remote patrol unmanned machine and send the video information of returning, therefore need to use multilevel relay equipment, trunking progression is one-level; Modulation /demodulation module in trunking (distance of trunking general distance grounded receiving station than the transmission and reception of modulation /demodulation module apart from closer) receives and demodulated video information with frequency A, then after giving processor transfer process, send to again modulation /demodulation module, this module is modulated with frequency B and is sent, grounded receiving station also receives and demodulated video information with frequency B simultaneously, watches process to after demodulation receiving station staff; In this process, can (patrol unmanned machine just taken off with grounded receiving station distance also not more than 20 kilometers time) be that grounded receiving station simultaneously receives with frequency B video information that trunking sends and receives with frequency A the video information that remote patrol unmanned machine sends for some time, need ground station according to Real-time Transport Protocol, after video is integrated, watch process to receiving station staff.
If each operating distance of remote patrol unmanned machine is within 35 kilometers, one-level relaying just can be used just can to realize, and when patrolling and examining apart from time distant, centre just needs multilevel relay.
Embodiment three:
When use multilevel relay time, will more complicated some, detailed process is as follows:
First order trunking transmission frequency uses B all the time, receive frequency brings into use A, when remote patrol unmanned machine flies over first order trunking, soon (can pass through investigation signal strength signal intensity) when arrival second level trunking, the receive frequency arranging first order trunking is the video data that C forwards to receive second level trunking with frequency C.
Second level trunking transmission frequency uses C all the time, receive frequency brings into use A, when remote patrol unmanned machine flies over second level trunking, when soon arriving third level trunking, the receive frequency arranging second level trunking is that D forwards with frequency D the video data of coming to receive third level trunking.
The like, afterbody trunking receives the video information of remote patrol unmanned machine all the time with frequency A, send to the trunking of penultimate stage with fixing transmission frequency.
