In the power emergency communication network based on microwave technology set up, strain insulator tower has an independent link, airborne sets
Using this link of system when standby different with individual soldier's equipment.
In the power emergency communication network based on microwave technology set up, mobile unit has independent link, for receiving
And show airborne equipment or the video of individual soldier's equipment collection, and by being arranged at command centre's intranet server program request.
1st, line walking communication system general introduction
When using aircraft line walking or artificial line walking, air craft carried equipment or individual soldier's equipment are referred to anchor support, scene
Wave car and carry out real-time Communication for Power, the image information of line walking is transmitted to application server or command centre, by this system, dispatches
Hall can watch that air craft carried equipment shoots video, individual soldier's equipment shoots video additionally it is possible to according to real-time video to patrolling in real time
Informant person carries out action commander；The real-time line walking image that application server can be returned to transmission is processed.
2nd, air craft carried equipment
Air craft carried equipment carries out high-definition image, regards to equipment such as the wire of power transmission line, wire clamp, drainage thread, anchor supports
Frequency gathers, and gathered data, after Video compression, passes to anchor support through microwave data transmission link, receives anchor support transmission
Instruction, carry out hovering, the reciprocal task such as flight, change the work such as optical pickocff focal length.For avoiding fuselage to block, in machine
Abdomen, machine the back of the body each dress one, antenna, gain based on 5dBi, antenna length about 150mm.
3rd, individual soldier's equipment
Individual soldier bears omnidirectional antenna, directly communicates with anchor support.
4th, command car mobile unit
Command car, as floor manager place, receives the high-definition video signal that individual soldier or air craft carried equipment transmit, and shows
It is shown on high definition screen, video is preserved simultaneously, can be with video playback.
Because data transfer rate is high, radio frequency link gain need to be improved and solve the problems, such as error rates of data, command car configure high
The beam antenna platform of gain, antenna is arranged on 5m elevating lever, and for convenience of antenna alignment, masthead installs head.
5th, strain insulator tower is constituted
HD video is passed through microwave transmission to anchor support by air craft carried equipment and individual soldier's equipment, and video is led to by anchor support
Cross the intranet server that optical fiber is sent to command centre, aircraft and list can be commanded by anchor support microwave equipment by command centre
Soldier；Support the two-way HD video transmission of ground control's car and anchor support.
It is considered to provide independent link for it under anchor support networking model, to reduce threshold level, and anchor support networking
Mode of flight device and individual soldier can not be simultaneously using systems.Equally, command car link is also single.Aircraft watched by command car
Airborne equipment or the video of individual soldier's equipment collection, by being arranged at the server program request of general headquarters of electric company.
Two complete equipments are had on anchor support, corresponds to air craft carried equipment (or individual soldier's equipment), corresponding command car respectively.Corresponding
Air craft carried equipment (or individual soldier's equipment) uses fan antenna, and for resisting signal fadeout, left and right two direction of tower is each to place two
Group fan antenna carries out diversity reception, therefore has 4 groups；Corresponding commander's vehicle device uses omnidirectional antenna, has 2.Antenna is pacified
It is contained in anchor support half waist, height about 30m.
Consider that equipment power dissipation is limited, solar energy and high voltage power transmission inductive power supply.
On anchor support, equipment is typically in off working state, just opens and use when only starting task.Opening ways have two
Kind：The remote control of remote scheduling hall is opened and scene is artificial opens.
Under anchor support networking model, it is wirelessly transferred using anti-multipath Microwave transmission technology, frequency selects 6GHz, aircraft
Upper abdomen carries on the back double antenna, and two groups of fan antennas are installed in the every direction of anchor support access station, for solving antenna footprint and antenna gain
Contradiction, every group of fan antenna form by multiple narrow fan antenna spelling groups, and final one group of antenna can cover more than 50 degree of sector
Scope, the high about 600mm of each fan antenna, wide 150mm, after triantennary spelling group, about 600mm × 500mm, antenna gain 20dBi.
Aircraft easily waves, and on aircraft, antenna gain can not be too high, optional highest 5dBi.
Calculated thus it is speculated that ability required for airborne equipment on the basis of farthest 16km, and loading demands.Because equipment energy
Power is limited, does not consider non-line-of-sight propagation situation, the limited height even so, aircraft goes up to the air, and anchor support antenna height is limited, must
So there is multipath, and then lead to level to decline, for ensureing transmission reliability, dual-antenna reception on tower, path loss is pressed with distance 3
Power rule increase reference model calculate, in addition reserve again 10dB about fading margin.
Communicate between individual soldier and tower and communicate it is considered to human motion waves can not use high-gain aerial similar to machine-tower, simultaneously
Individual soldier's antenna height is limited, and the decline that signal causes through multipath transmisstion is deeper, and therefore individual soldier's transmitting power of equipment needs to improve, from
Operator's health sets out it is proposed that as follows by way of wireless local area network：
Individual soldier is not directly communicated with anchor support, first passes through wireless local area network technology and communicates with neighbouring trunking, in
The equipment that continues is communicated with anchor support again, thus constituting link.Trunking uses broad beam antenna, and gain carries compared with omnidirectional antenna
High 15dB about, antenna size about 300mm × 300mm, so can reduce transmission power.Trunking with stopping with frame, due to
Antenna beam width, therefore direction be aligned easily operates.In addition, hold must keep regarding between telescope individual soldier and trunking leading to, and away from
From less than 150m.
For making command car stand unfettered it is easy to use, tower is installed two omnidirectional antennas；With farthest 16km it is
Benchmark is calculated, and is communicated because command car can stop, and for improving communication quality, is command car configuration high-gain orientation sky
Line, carries out antenna alignment using head under manual key wire prosecutor formula；Even so, antenna broad beam still introduces multipath making
Become decline, for ensureing transmission reliability, the reference model that path loss is pressed with distance 3 power rule increases calculates, and considers further that and stays
10dB about fading margin.
It is ensured that the key of transmission quality is to forward the signal-to-noise ratio degradation bringing as far as possible little for simulation forwards, root
Theoretical according to frequency conversion, the output frequency of forwarding is：
Fout=M Fin ± N FLO
Due to each channel width 30MHz, adjacent channel spacing takes 10MHz, and four passages occupy a width of 150MHz of band, if
Interval will be forwarded to be set to 250MHz, can reasonable suppression spurious frequency with narrow band filter.
