Description

The terrestrial space light-wave communication system

Technical field

Wireless information communication system.

Background

At present by externally providing " location-based " business in the environment such as cell phone, PDA(Personal Digital Assistant), the hand-held device that is installed in the monitor on the vehicle.It is used that this information can be various terminal uses.For example, the driver can obtain to indicate the image of the map of its position, and perhaps the deliveryman can obtain about driving to the direction of desired location.

Present global positioning system (GPS) comprises the receiver of only working in the scope that satellite launch vehicle can arrive, thereby limits the use of environment out of doors of this system.Even like this, overhead and barrier on every side also can cause disharmonious business such as trees and urban corridor.In order to obtain optimum resolution, must there be obstacle between user and the sky.In addition, because the restriction of GPS resolution, so the location-based service application of claimed accuracy within several meters can not.

Height among the GPS is measured much more inaccurate than lat/lon.In addition, the cell phone triangulation based on the measurement of the relative distance of cell phone and a plurality of sub-districts pylon can't provide measuring of any height.Therefore, even current cellular technology finally can develop into the cell phone or the PDA that can accurately locate in the building, it can not provide yet determines the required elevation information of user place floor.In other words, when using GPS separately, user (or other people) knows his (she) position on X-axis and Y-axis, but does not know the position on the Z axle.Therefore, the overall space resolution of this system only limits to tens of rice.

Safeguard the required investment height of location-based service communication system (even without widely applying required accurate spatial resolution) of these complexity and energy-intensive, and this trend keeps always.

In the best condition, the realization of location-based business provides " information in time " of information to transmit in the place of needs and the time that needs with the required and suitable language of recipient usually.But, under a large amount of situations, the user may wish under direct environment one of the many objects of identification or target, and available system lacks certainty aspect the required spatial accuracy (accuracy of positional information) when the someone for example stands in the front, hotel and receives menu, receives the hypertext information of the relevant special object of watching or receive the extend information of the sign of seeing in the relevant transition terminal but can't reading in the museum at present.This is restriction-can not the provide space selective power (just can not select in the environment one of various features to be used for identification) of present location-based business.A kind of current methods of local transmission information is based on Infrared Data Association (IrDA) infrared communication protocol.But, this agreement be special for local aided measurement device to device communication (for example notebook computer is communicated by letter to PDA to PDA or PDA) design, rather than as the integrated component of communication network.Because a plurality of reflectors of IrDA inexpectancy tight spacing are worked simultaneously, so this agreement is being uncomplicated aspect the network conflict arbitration.Therefore, promote may task based on the business of mark at distance (for example one of a plurality of overhead signs from airport terminal) acquisition of information easily in, IrDA is not the good candidate of communication strategy.In general, IrDA realization inexpectancy is worked under bright and beautiful sunshine, thereby has further reduced the effective range of outdoor medium.

At present, the environmental labelling system " the long-range infrared sign of listening " of for example selling with TALKING SIGNS  trade mark (RIAS) makes the blind person and the disability user that can't read can locate and discerns boundary mark, sign and relevant facility.It adopts the short speech sound message that is stored in the infrared transmitter to serve as a mark.User's hand held receiver will be converted to the speech message that can listen from the transmission of lightwave signal.Receiver is that special relative uniformity for indoor or outdoor sensitivity designs.The give information control of the scope that covers (from several centimetres to more than 30 meters) and width (from 6 degree to 360 angles of spending) of infrared beam pattern.The height space selectivity of RIAS receiver is that the characteristic of frequency modulation (FM) infrared signal from emission obtains, and wherein the FM phase-locked link demodulation guarantees to have only the strongest signal can pass to the user in a plurality of possible compete signals.At this on the one hand, the strongest signal is meant the signal that has maximum signal energies on receiver, and be the result of following three factors: the relative power output of (1) competition reflector, (2) relative distance from the competition reflector to receiver, and the light wave detector of (3) receiver is with respect to the angle of each competition reflector; The angle of receiver is topmost factor, and the information of controlling which mark is delivered to receiver.

Many existing systems can't provide following advantage: the three-dimensional localization ability, the simplification of the maintenance relevant with energy requirement, the timely information of ad-hoc location or object in the direct environment, a plurality of reflectors can not got rid of one regioselective system from multinomial, be convenient to the easy renewal of information, perhaps to pinpoint position remote transmission mass data.
