Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As it is shown on figure 3, cascade compact shelving archives light curtain of the present utility model, the light curtain group cascaded successively including at least two groups
Part, often group light curtain assembly all includes receiving unit 1 and transmitter unit 2.The reception unit 1 of this at least two groups light curtain assembly
Being positioned at the same side, the transmitter unit 2 of light curtain assembly is positioned at opposite side.And the reception unit 1 of at least two group light curtain assemblies
Being commonly connected to a power port, be used in conjunction with a signal output port, head and the tail arranged adjacent successively becomes string to install,
Equally, the transmitter unit 2 of at least two group light curtain assemblies is used in conjunction with a power port, the most adjacent installation that forms a line.
And transmitter unit 2 is separately mounted on the relative side of adjacent concentrated archive shelf with receiving unit 1.
As in figure 2 it is shown, often the top of group transmitter unit 2 is provided with synchronous signal transmitter 3, synchronous signal transmitter 3
Lower section is provided with multiple emitter 5, and for signal scanning, and the top receiving unit 1 often organizing correspondence is provided with synchronizing signal
Receptor 4, the lower section of synchronous signal receiver 4 is corresponding with above-mentioned emitter 5 is provided with multiple receptor 6, with this shape
Become light curtain.For Yi Ban, connected by electric wire, i.e. between this synchronous signal transmitter 3 and synchronous signal receiver 4
This synchronizing signal is the signal of telecommunication, but if used in a big way, it is necessary to use longer electric wire, the most inconvenient
Laying and use in light curtain.Therefore, in order to use in the larger context, above-mentioned synchronous signal transmitter 3 He
Synchronous signal receiver 4 is respectively infrared transmitter and infrared remote receiver.As in figure 2 it is shown, such synchronous signal transmitter
Avoid the need between 3 and synchronous signal receiver 4 making to run wires to, it is only necessary to synchronize to realize by optical signal.
In use, synchronous signal transmitter 3 first launches a synchronizing signal, and the synchronous signal receiver 4 of correspondence receives same
After step signal, infrared signal launched the most successively by the multiple emitters 5 in the transmitter unit 2 of this group light curtain assembly, and light curtain
The receptor 6 received in unit 1 of assembly receives infrared signal successively, as long as occurring in that stop between light curtain assembly, connects
Receive device 6 just cannot receive signal, will output signal stopping concentrated archive shelf movement.But such structure has one
Defect, it is simply that when many group light curtain assemblies cascades, a upper light curtain assembly after synchronizing signal is directed at, a upper light curtain group
The emitter 5 of part is launched successively and time receptor 6 receives successively, owing to the wireless optical launched has certain transmitting angle,
The synchronous signal receiver 4 in next light curtain assembly may be affected, as in figure 2 it is shown, be in next light curtain assembly
Synchronous signal receiver 4 may receive the signal of the emitter 5 in one group of light curtain assembly by mistake, and proceeds by scan operation.
Therefore, such structure easily causes maloperation.
Therefore, as it is shown on figure 3, the cascade concentrated archive shelf light curtain of this utility model embodiment, often group light curtain assembly is same

Signal projector 7 and feedback signal receiver 8 are respectively as the reception of synchronous feedback signal and transmitting.This feedback signal is sent out
Emitter 7 and feedback signal receiver 8 are also respectively infrared transmitter and infrared remote receiver.
During use, synchronizing signal sends from the synchronous signal transmitter 3 receiving unit 1, sends a specific synchronization
Sequential, simultaneously corresponding in transmitter unit 2 synchronous signal receiver 4 is opened, and is demodulated out by the signal of reception, sentences
Whether disconnected be the synchronizing signal sent in the synchronous signal transmitter 3 receiving unit 1 of coupling, if it is not, emitter 5
Do not perform ensuing scanning to launch, but proceed synchronous detecting, until synchronizing successfully；If synchronizing signal connects
Harvest into, feedback signal emitter 7 in execution transmitter unit 2 is sent synchronous feedback signal, after being sent completely, perform
The sequential scan of emitter 5 sends, and after sequential scan performs to terminate, re-synchronization detects, and circulates with this.
After synchronous signal transmitter 3 in reception unit 1 has sent synchronizing signal, feedback signal reception therein will be opened
Device 8, demodulates out by the signal of reception, it may be judged whether for synchronous feedback signal, will return if it is not, receive unit 1
Synchronizing the incipient stage, synchronous signal transmitter 3 will resend synchronizing signal, again detection synchronous feedback signal, effectively
Until synchronous feedback success in time, just meeting opening sequence radio scanner 6, scans the most successively, and the scan period terminates
After, re-start synchronization, once circulate.
Owing to the most first carrying out synchronized transmission operation, just can carry out sequential scan after only synchronizing to run succeeded, which ensure that
The corresponding harmonious property between light curtain.And synchronous signal receiver 4 is positioned in transmitter unit 2, even if in scanning
During, any scanning signal launched by the emitter 5 in the transmitter unit 2 of adjacent light curtain assembly, due to this synchronization
Signal receiver 4 is positioned at the homonymy of emitter 5, and synchronous signal receiver 4 can not receive sending out of adjacent light curtain assembly
Penetrate the signal that in unit 2, emitter 5 issues, even if the reception unit 1 of adjacent light curtain assembly sends synchronizing signal,
Due to distant, the synchronous signal receiver 4 of this group is also impossible to receive synchronizing signal simultaneously, so will not produce it
Raw interference.
And this cascade document shelf light curtain, when after synchronized transmission success, needs to carry out synchronous feedback signal, is used for determining together
Step is the most successful, determines the cycle sequential relationship of scanning, re-starts if it fails, synchronize needs；If it is successful, will
Execution sequence scan operation, even if the receptor 6 now receiving unit 1 receives certain co-channel interference light, also can be by
In keeping concordance with corresponding emitter, will misplace with interference or flood interference, thus it will be dynamic not result in interference wrong report
Make, it is ensured that the reliability of whole system.
Transmitter unit 2 due to the radiation direction between synchronous signal transmitter and synchronous signal receiver Yu light curtain assembly
Emitter 5 and the receptor 6 receiving unit 1 between light in opposite direction, therefore, the cascade of this light curtain assembly with
After, even if the light that the emitter 5 of a upper light curtain assembly is launched is injected in the receptor 6 of next light curtain assembly, by
Do not have synchronous signal transmitter 3 to launch synchronizing signal in next light curtain assembly, next light curtain assembly also will not be made to enter
Row scanning.
