This application is a continuation-in-part of International Patent Application No. PCT/CN2007/000937 with an international filing date of Mar. 22, 2007, the contents of which are incorporated herein by reference.
The invention relates generally to an information transceiver apparatus, and more particularly to a floating cable-fed information transceiver apparatus.
Communication towers anchored to the ground or attached to mobile carriers are generally used to implement long-range transmission and wide area coverage in the fields of communication, navigation and positioning, sensing, optics and infrared imaging. They allow detecting, receiving, and relaying various types of information and signals.
However, since the height of communication towers is limited their coverage area is correspondingly limited. In addition, performance agility and flexibility of the communication towers is relatively poor. Although planes, balloons and zeppelins have been employed as substitute of communication towers, their high cost, large size, low robustness, and the need for high-frequency of refueling makes them impracticable for many applications.
Accordingly much opportunity for improvement remains in this area of technology.
In one embodiment provided is a floating cable-fed information transceiver apparatus, comprising: a suspended object; an information transceiving device connected to the suspended object; a carrier; a power supply arranged inside the carrier; and a power cable line having a first end and a second end; wherein the first end of the power cable line is connected to the information transceiving device, and the second end is connected to the power supply.
In certain embodiments, the suspended object is a balloon, an zeppelin, a suspended object with a propeller, a suspended object with a propeller and a rudder, or a combination thereof.
In certain embodiments, the suspended object is connected to the power supply via the power cable line.
In certain embodiments, the information transceiving device transmits and/or receives information.
In certain embodiments, the information transceiving device transmits and receives a radio signal, an optical signal or an infrared signal.
In certain embodiments, the floating cable-fed information transceiver apparatus further comprises an information processing terminal having one of its ends connected to the information transceiving device.
In certain embodiments, the information processing terminal is disposed inside the carrier.
In certain embodiments, the information processing terminal is disposed outside the carrier.
In certain embodiments, the information transceiving device is disposed inside the suspended object.
In certain embodiments, the information transceiving device is disposed outside the suspended object.
In certain embodiments, the suspended object is connected to the carrier via one or more fixed lines.
In certain embodiments, the suspended object is a balloon or a zeppelin, a gas pipe is disposed between the carrier and the suspended object.
In certain embodiments, the floating cable-fed information transceiver apparatus further comprises an altitude sensor and an altitude controller being connected with the suspended object or the information transceiving device.
In certain embodiments, the floating cable-fed information transceiver apparatus further comprises a navigation and positioning device being connected with the suspended object or the information transceiving device.
In certain embodiments, the information transceiving device comprises a control rudder.
To reduce the size and the weight of the information transceiving device, the information transceiving device may be simply a front end with an antenna, an up-converter and a down-converter. In case that a loss of a carrier frequency signal is low, only an antenna, a filter, a low-noise amplifier and a power amplifier are needed. At this time, a back end is installed on a carrier on the ground or water surface, and is connected to the information transceiving device via fiber optics. The information transceiving device may also be a complete transceiver.
Energy may be provided from the ground or the water surface, so as to reduce a size, cost and weight of the suspended object and the information transceiving device.
From a broader view, a sensor may be installed on the information transceiving device for irregularly detecting a flying direction and a flying angle, and for avoiding crash.
Compared with the prior art, advantages of the invention comprises:
Other advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:
The information transceiving device 2 is arranged inside the suspended object 1 for receiving and transmitting information from and to the outside. Directions of transmitting or receiving information may be fixed or adjusted by the direction sensor and/or the rudder on the suspended object 1, or by the carrier 4. It should be noted that in other embodiments, the information transceiving device 2 may be arranged outside the suspended object 1, and the direction sensor and the rudder may be directly installed on the information transceiving device 2.
The power cable line 3 connects the information transceiving device 2 to the power supply 6.
The carrier 4 is a terrestrial carrier, such as an automotive, or an aquatic carrier, such as a ship.
The information transceiving device 2 is connected to the power supply 6 via the power cable line 3 for supplying power thereto. If the suspended object 1 needs power, the power supply 6 may supply power thereto.
The suspended object 1 moves synchronously with the carrier. For example, the suspended object 1 may be made as a helicopter-like flying object that is powered by electricity instead of fuel, controlled by a carrier on the ground or water surface, moves along with a motive carrier, and freely sets a height and a direction of the information transceiving device.
To avoid air crash, a warning lamp or a radio warning device may be installed on the suspended object 1.
If the suspended object 1 is a balloon or a zeppelin, an energy source, such as a gas source is disposed on the carrier 4 to supply, e.g., gas to the suspended object 1. In this way, the height of the suspended object 1 may be adjusted. In this embodiment, the shape of the suspended object 1 is chosen to be circular, elliptical or oblate, so as to easily change directions and to decrease the wind resistance.
The suspended object 1 and the information transceiving device 2 cooperate with the altitude sensor 8 and the altitude controller 9 to control altitudes, locations and directions of the suspended object 1, and thus to perform control of the signal transceiving direction.
In addition, the suspended object 1 and the information transceiving device 2 may cooperate with the navigation and positioning device 10, to determine, control and adjust positions, locations and altitudes of the suspended object 1. It should be noted further that in other embodiments, a control rudder is directly installed on the information transceiving device 2 and assists in changing directions of receiving/transmitting information.
In another embodiment, a propeller-like device or a direction rudder is installed on the suspended object 1 and/or the information transceiving device 2. The propeller-like device or the direction rudder make use of information provided by the navigation and positioning device 10 to adjust positions, locations and altitudes of the suspended object 1 and the information transceiving device 2.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore-described merely being preferred or exemplary embodiments.
