Abstract
The present invention provides a lifting antenna system by adopting the microwave and the laser bean of a screw propeller, which overcomes the problem that the prior hydraulic lifting antenna is insufficient in height. The present invention includes a high-attitude device 1 and a ground device 2. The ground device provides power to the high-attitude device through the microwave and the laser bean, so that the screw propeller drives the high-attitude device to blast off and the height can extend to several decameters and even several hectometers. The high-attitude device is provided with a wireless device for assuming the relay mission of 'far-end user' and 'ground device' so that the communication distance surpasses 100-200km and overcomes the obstacles of natural mountains and urban buildings. Compared with helicopters and unmanned navigation, the system has the advantages of low maintenance cost, no noise and continuous operation; compared with balloons and airships, the system has the advantages of quicker and more convenient lifting, small size of the high-attitude device and the difficulty being discovered and destroyed by the enemy. The system is particularly suitable for flexible battleground communication and the spot tracing communication of public security/safety departments and can also achieve news 'field pickup' in the true sense.
Description
The present invention relates to a kind of antenna system of radio communication, automatic lifting especially quickly and easily, adjustable height can extend to tens meters to hundreds of rice, is the general hydraulic lifting antenna height that is beyond one's reach, and is particularly suitable for the flexible needs in battlefield.
At present, radio communication is subjected to the restriction of dual-mode antenna height, be subjected to receiving and dispatching blocking of high-lager building, massif between 2 easily, even can not pass too far on the sea level, reason is that the earth is a spherosome, and the surface is a circular arc, the general 50km that surpasses has been not visual air line distance just, so want to increase the communication distance of principal character by the wireless device of straightline propagation, best bet is the height that increases dual-mode antenna, allow become visual between 2 of the transmitting-receivings as far as possible.Traditional way is that dual-mode antenna is erected at building, high mountain top, and also will build iron tower in the above and increase antenna height as far as possible, and cost is very high, and general iron tower cost is about 10,000 yuans of each meter, and only is fit to the communication between the fixing point.Along with social progress, television broadcasting has been tending towards on-the-spot broadcasting, is about to on-the-spot image, the sound that takes place and directly is dealt into TV station, and TV station directly transmits to the user without editor or through simple editor, requires short as far as possible time delay.Although " news spot ", " live news " class program have all done in a lot of TV stations, they are not real on-the-spot broadcasting generally in fact, be after image, the sound of news spot are shot with video-corder with video camera, tape delivered to play again after TV station's editing and processing, middle through recording, tape transmission, editor, broadcast plurality of processes, so say not it is " on-the-spot broadcasting " on the essential meaning, had microwave, laser beam liftable antenna system just can realize the on-the-spot broadcasting of real meaning now.The audio-video signal of video camera is sent to the microwave on the mobile unit of next door, the communication forwarding unit on laser beam energy automatic lifting antenna system top " high-altitude device " by wireless mode, again signal is directly transmitted go back to TV station, and TV station plays again.Whole process is continuous, and time delay is less than 1 second.Equally, this antenna is fit to the scene tracking communication of flexible field communication, public security/security department.
At present, the height of known hydraulic lifting antenna is the highest also with regard to more than 10 meters, communication distance is still limited, particularly in built-up city, tens meters at least of common depth of buildings, then more than 100 meter to 200 meters of height is so can't cross blocking of high building with common hydraulic lifting antenna communication; Army in the mountain area, Qiu Lin runs into natural massif and blocks, communication distance with common hydraulic lifting antenna is also limited, even on Plain, desert, sea level, can not pass too far, reason is that the earth is a spherosome, the surface is a circular arc, the general 50km that surpasses has been not visual air line distance just, and communication distance is also with regard to about 50km.
In order to overcome the deficiency of existing hydraulic lifting antenna height, the invention provides a kind of microwave, laser beam liftable antenna system that adopts screw, automatic lifting quickly and easily, adjustable height can extend to tens meters to hundreds of rice, be that general hydraulic lifting antenna is beyond one's reach highly, be particularly suitable for the flexible needs in battlefield.
The technical solution adopted for the present invention to solve the technical problems is: be made up of " high-altitude device " and " ground installation " two large divisions." high-altitude device " beams back " ground installation " by top gyroscope/GPS position indicator, " ground installation " passes through to calculate with the GPS locating information of oneself again, send the coordinate position of commands for controlling " high-altitude device ", and the microwave of " high-altitude device ", receive direction and the microwave of " ground installation ", the transmit direction of laser beam transmitter of laser beam receiver are aimed at mutually, form straight line, guarantee that microwave, laser beam can normally receive and launch." ground installation " provides energy for " high-altitude device " by microwave, laser beam, makes the screw-propeller lifting of " high-altitude device " and drives " high-altitude device " lift-off; Running orbit can not departed from by factors such as wind-force in longitude, latitude coordinate position that the lateral attitude of " high-altitude device " (longitude, latitude) is set by " high-altitude device " horizontal several air push device controls.Above " high-altitude device " radio reception and forwarding unit (or other communication equipments and lighting apparatus etc.) can also be installed, " ground installation " transmitted to receive be transmitted to " remote subscriber " (as command centre etc.) again, can receive simultaneously the signal of remote subscriber again, be transmitted to " ground installation " again, make to keep unidirectional or two-way communication between " remote subscriber " and " ground installation ".
Of the present inventionly have a mind to effect and be, the height by the rising antenna reaches tens meters to hundreds of rice, makes communication distance surpass 100～200km, can cross stopping of natural massif, City Building, installs, lifting can finish in one minute, and is convenient, flexible.And compare with helicopter, unmanned machine, the native system maintenance cost is low, and noiseless during use is as long as " ground installation " provides uninterrupted power supply to move continuously; Communicate by letter with fire balloon, dirigible and to compare, lifting is faster, and the volume of " high-altitude device " is little flexibly, is difficult for being found and destroying by the enemy.
