Description
Technical field
The present invention relates to a kind of radio communication technology field, specifically a kind of wireless simultaneous interpretation system being applied to big assembly.
Background technology
Traditional wireless simultaneous interpretation system is used in indoor meeting room usually, and for some large-scale rallies, the place of rally may out of doors, also in multiple indoor, or both may have.At this moment, if apply traditional wireless simultaneous interpretation system, just cannot get a desired effect.
Traditional wireless simultaneous interpretation system, is generally divided into following several types by technique classification:
Use the infrared simultaneous interpretation system of infrared communication.Be easy to the severe jamming being subject to outdoor daylight Infrared when system uses out of doors, cause system normally to work.
Use the analog-modulated radio frequency simultaneous interpretation system of U section or FM frequency range.The frequency range that system uses has different use regulations in the radio control department of every country, needs application, otherwise can not legally use before using.Thus constrain the scope of its application.In addition, because system there is no cryptographic means, and technology is simple, in use easily by other people interference, even captures broadcast right.
Use the simultaneous interpretation system of WiFi technology.Due to the access limited amount of WIFI system, the requirement that people up to ten thousand uses simultaneously can not be met.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of wireless simultaneous interpretation system being applied to big assembly, the switching in energy feasible region, the service efficiency improving frequency, same frequency do not interfere with each other mutually and meet people up to ten thousand and use simultaneously.
The present invention describes a kind of wireless simultaneous interpretation system being applied to big assembly, comprise main control computer, and main control computer is electrically connected with at least two indoor radio signal transmitters and at least one outdoor radio signal senders, in main control computer control room, the signal of radio signal senders and outdoor radio signal senders sends and information channel switching.Signal receiver by the signal strength signal intensity perception of the radio signal senders of indoor or outdoors, the radio signal senders that choice for use is current to be corresponded and the signalling channel of correspondence thereof.In addition, application according to the present invention also has following additional technical feature in the wireless simultaneous interpretation system of big assembly, according to some embodiments of the present invention, further concrete, described main control computer comprises frequency-hopping spread spectrum module, and the transmitting terminal of frequency-hopping spread spectrum module is connected in radio signal senders and outdoor radio signal senders.
The invention has the beneficial effects as follows: 1, receiver is when listening to the wireless transceiver signalling channel of zones of different, seamless switching can be carried out, and allocated in advance use frequency or the signalling channel of indoor radio signal transmitter or outdoor radio signal senders by main control computer, the region-wide of covering can be guaranteed and there will not be with frequency interference problem mutually; 2, frequency-hopping spread spectrum module, coordinates indoor radio signal transmitter and outdoor radio signal senders can meet people up to ten thousand and uses simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
Below with reference to Fig. 1, the wireless simultaneous interpretation system being applied to big assembly according to the embodiment of the present invention is described.
The present invention describes a kind of wireless simultaneous interpretation system being applied to big assembly, comprise main control computer 2, and main control computer 2 is electrically connected with at least two indoor radio signal transmitters 1 and at least one outdoor radio signal senders 3, receiving and sending messages and information channel switching in main control computer 2 control room between radio signal senders 1 and outdoor radio signal senders 3.Further concrete, described main control computer 2 comprises frequency-hopping spread spectrum module 2, and the transmitting terminal of frequency-hopping spread spectrum module 2 is electrically connected in radio signal senders 1 and outdoor radio signal senders 3 respectively.
Outdoor radio signal senders 3 belongs to the covering of high-power wide area, by the frequency point allocation of main control computer 2, also can ensure mutually to stagger with the frequency of indoor radio signal transmitter 1.
When participant listens to conference guide in indoor, the indoor radio signal transmitter 1 in region uses broadcast frequency A.When participant moves towards another one overlay area B from overlay area A, wireless receiver 1 can detect that the signal of frequency A weakens, and the signal of frequency B is in enhancing.So after the signal of frequency A is attenuated to certain switching threshold values, automatically communication frequency is switched on frequency B, the language channels number simultaneously also selecting back participant original.This completes seamless receipt handoff procedure.
Signal transmits and adopts the mode of broadcast to carry out, although communication mode is unidirectional, receiver, also without quantitative restriction, can meet the functional requirement of large-scale simultaneous interpretation completely.
Signal adopts the spread spectrum of FHSS, by the modulation of " pseudo noise code ", the centre frequency of carrier operation is constantly jumped conversion, thus reaches base band and encrypt and jamproof object.
This structure uses common 2.4G frequency range, develops a kind ofly can be applied to indoor, outdoor people up to ten thousand and to gather the large-scale wireless simultaneous interpretation system made.2.4G frequency range is the ISM band of exempting from the world to apply for, can freely use in the world.Indoor, open air all can use, and we have carried out digital encryption to it, ensure that the fail safe of use.Adopt the mode of broadcast, make the quantity of indoor wireless transceivers 1 or outdoor wireless transceiver 3 without restriction.
With trying one's best, few frequency passes more voice channel.At adjacent covering overlapping area, in order to avoid the appearance of co-channel interference, distribute different frequency hopping points unitedly to each overlay area by main control computer 2.Point is covered for each, is connected to each other by wired mode and accesses main control computer 2, control in real time and monitor the RST of each wireless coverage point.
Wireless receiver 1 adopts the design means of double antenna, strengthens the receiving ability at different directions.In addition, the gain of these two antennas also has different, can at overflow or complementary when crossing weak.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement or improvement etc., all should be included within protection scope of the present invention.
