The use demand of network layout.
According to the wireless quantum key distribution equipment of the present invention, it includes：Modules A lice-OD occurs for quantum, for producing
Third contact of a total solar or lunar eclipse quantum；First control unit Alice-P, modules A lice-OD occurs with the quantum and associates；Quantum receiving module Bob-
OD, module occurs with the quantum and is used cooperatively；Second control unit BOB-ID, closed with the quantum receiving module Bob-OD
Connection；The quantum occurs the modules A lice-OD and quantum receiving module Bob-OD and used in pairs, and passes through transmission of visible light
Signal.
Further, the quantum generation modules A lice-OD connects the first control unit Alice- by Ethernet
P。
Further, the first control unit Alice-P receives " acquisition key " request.
Further, the first control unit Alice-P is connected by way of wireless connection with user terminal.
Further, in same time, the quantum key distribution equipment is additionally provided with some first auxiliary unit Alice-
S, the first auxiliary unit Alice-S are connected with the first control unit Alice-P.
Further, the first auxiliary unit Alice-S receives " acquisition key " request, and the request is sent to
First control unit Alice-P.
Further, the quantum receiving module Bob-OD is provided with some detectors, each in some detectors
Individual can be matched with corresponding quantum distribution module uses.
Further, the quantum key distribution equipment is additionally provided with some second auxiliary units, second auxiliary unit
It is connected with the second controller.
Further, the quantum occurs to comprise at least laser in modules A lice-OD.
Further, the quantum occurs to pass through between the modules A lice-OD and quantum receiving module Bob-OD
The mode of relaying connects.
By the present invention, the wireless quantum key distribution equipment compared with prior art, eliminates lengthy and tedious optical fiber cloth
Net connects, and the connection use between skyscraper is more convenient, meanwhile, in certain circumstances, a quantum receiving module
With multiple quantum modules A lice-OD cooperatings can occur for Bob-OD, change each quantum in the past and modules A lice-OD occurs
A situation matched complete quantum receiving module Bob-OD just is needed, reduces quantum receiving module Bob-OD number
Amount, reduce city and arrange net construction cost, allow quantum communications to come into huge numbers of families.

Fig. 1 is prior art schematic diagram；
Fig. 2 is a kind of application scenarios of wireless quantum key distribution equipment of the invention；
Fig. 3 is a kind of topology layout schematic diagram of wireless quantum key distribution equipment of the invention；
【Embodiment】
As shown in Figures 2 and 3, it is the wireless quantum key distribution equipment of the present invention（Non- label）Application and its structural representation
Figure, the wireless quantum key distribution equipment wherein shown in Fig. 3 are a kind of topology layout embodiment of the invention.
The wireless quantum key distribution equipment comprises at least：Alice-OD, for producing light quantum；First control is single
First Alice-P, modules A lice-OD occurs with the quantum and associates；Quantum receiving module Bob-OD, mould occurs with the quantum
Block is used cooperatively；Second control unit BOB-ID, associated with the quantum receiving module Bob-OD；Module occurs for the quantum
Alice-OD is used in pairs with the quantum receiving module Bob-OD, and carries out wireless optical signal transmission by free space.
The quantum occur the modules A lice-OD and quantum receiving module Bob-OD actual installation and use up to
In outdoor, or both between connected mode be exposed in natural environment.Modules A lice-OD transmittings occur for the quantum can
See that light is communicated with the quantum receiving module Bob-OD.
The first control unit Alice-P is typically set with indoor, can be directly by wired or wirelessly
It is connected with application terminal, in the present embodiment, the quantum occurs modules A lice-OD and connects first control by Ethernet
Unit Alice-P.The first control unit Alice-P receives " acquisition key " request, and the amount is controlled according to the request
Son occurs modules A lice-OD and is communicated with the quantum receiving module Bob-OD and generate corresponding secret key.In some embodiments
In, if the quantum occurs the modules A lice-OD and quantum receiving module Bob-OD and generated compared with multi-key cipher, and part
In memory, then key that can be preferentially by the deposit sends application terminal to for deposit.
In view of the difference of practical application scene, setting for each submodule in modules A lice-OD occurs for the quantum
Put different.In the present embodiment, the quantum occurs modules A lice-OD and mainly includes light processing part：Laser LD,
It is decay Att, interference ring etc..But no matter if it is different, module at least laser LD occurs for the quantum, guarantee is most basic
