The conventional arrangement of upstream or downstream transmission optical signal is compared and seldom have time delay.
Light transmitting element 14 can receive image and send signal of telecommunication Tx from communication control unit 15, can be by image
Send signal of telecommunication Tx and be converted into image transmission optical signal OTx, and image can be sent optical signal OTx and apply
Transmission to the optical combiner 12 being connected (preferably, be directly connected to) with the optics of light transmitting element 14 is defeated
Enter waveguide 122.
Communication control unit 15 is interpreted in the signal of telecommunication received via beam splitter 11 and light receiving unit 13
Address, control command and data that Rx includes, and if it is determined that the address of interpretation is and respective optical
Connect the corresponding address of CCTV camera apparatus 10, then communication control unit 15 will be carried from the signal of telecommunication for receiving
The control command for taking or data output are to camera function control unit 16.If conversely, interpretation address with
Respective optical connection CCTV camera apparatus 10 are uncorrelated, then reception is ignored and abandoned to communication control unit 15
Order and data.
Communication control unit 15 can be based on the view data generation image transmission that graphics processing unit 17 is produced
Signal of telecommunication Tx, and can be according to the transmission of the control command extracted from the signal of telecommunication for receiving license relevant control life
Image is sent signal of telecommunication Tx outputs to light transmitting element 14 by order.
In one embodiment, communication control unit 15 is designed to support full duplex/half couple on demand
Work communication means or synchronous/asynchronous communication means so as to have for example with traditional multiple spot EIA-485/422 nets
The compatibility of network.
Camera function control unit 16 can according to the control command transmitted from communication control unit 15 or according to
Itself determine to control the lens, the imageing sensor dress that arrange in optics connects CCTV camera apparatus 10
Put, the function of memorizer and image procossing, Object identifying, calibration, coding etc..
Graphics processing unit 17 under the control of camera function control unit 16, from image sensor apparatus
The image of acquisition produces view data, then view data is sent to into communication control unit 15.
Arranging interface 18 can switch or the like to realize using dual-inline package (DIP).User
Communication control unit 15 can be set by address for referring to or the like via interface 18 is arranged.
Fig. 2 is to illustrate to connect including the optics of multiple use passive optical components according to an embodiment of the invention
The optics for connecing CCTV camera apparatus connects the diagram of CCTV systems.
Optics connection CCTV television systems 20 may include master control server 21, descending optical cable 22, up
Optical cable 23 connects CCTV camera apparatus 24 with being connected in series from optics.
Connecting CCTV camera apparatus 24 from optics can use the multipoint iterationses of full-duplex/half-duplex type to be connected
Connect.
Exported with particular address from optics connection CCTV camera apparatus 24 by master control server 21
Downlink optical signal the beam splitter for connecting CCTV camera apparatus 24 is applied to from optics along descending optical cable 22
Descending input waveguide.
Each is from optics connection CCTV camera apparatus 24 from by will be from the detached separation light of downlink optical signal
Signal carries out the reception signal of telecommunication extraction address that electric conversion is obtained, and if the address extracted is and it
Itself corresponding address, then process and be included in the control command or data received in the signal of telecommunication, if extracted
Address be not address corresponding with its own, then abandon receive the signal of telecommunication.
Additionally, connecting uplink optical signal that CCTV camera apparatus 24 export via up from optics by each
Optical cable 23 is applied to from optics along the path for arriving master control server 21 upwards and connects CCTV camera apparatus
The up input waveguide of 24 optical combiner.
In this case, CCTV camera apparatus 24 are connected when uplink optical signal is applied to from optics
During the up input waveguide of optical combiner, uplink optical signal is immediately via the combination output waveguide of optical combiner
It is output to up optical cable 23.Therefore, do not exist from optics and connect CCTV camera apparatus 24 to up light
The process operation that signal is specifically performed.
Simultaneously as may not realize that the up light for passing through from optics connection CCTV camera apparatus 24
The presence of signal, therefore competing method can not be adopted from optics connection CCTV camera apparatus 24, and can make
With non-competing method (such as time-division communication method, polling method or interrupt method) as media interviews control
System (MAC) method.
In one embodiment, do to prevent uplink optical signal and image from sending the signal between optical signal
Disturb, using time-division communication method, any one can be in main control from optics connection CCTV camera apparatus 24
Server 21 and from optics connection CCTV camera apparatus 24 all by time synchronized in the state of, according to
Predetermined decimation-in-time algorithm is exported to main control service in each time interval using view data as uplink optical signal
Device 21.
In one embodiment, do to prevent uplink optical signal and image from sending the signal between optical signal
Disturb, using polling method, master control server 21 can be called specific from optics company according to predetermined decimation-in-time algorithm
Connect CCTV camera apparatus 24, and it is invoked it is specific can be by from optics connection CCTV camera apparatus 24
View data is exported as uplink optical signal.
In another embodiment, according to interrupt method, there is the specific of event and connected CCTV from optics
Camera apparatus 24 can produce interruption, and can optically export the interruption of generation.For example, can be in situations below
It is lower to interrupt：The shape of people is detected in the image of finite region, abnormal row is observed in crowd
For, or camera function generation problem.
In this case, master control server 21 can be received and the corresponding uplink optical signal of interruption, and can
By including data is activation license downlink optical signal be sent to produce interruption from optics connect CCTV phases
Machine equipment 24.Only having been received by the specific of data is activation license can from optics connection CCTV camera apparatus 24
It is allowed to be exported view data as uplink optical signal.
The executable control of master control server 21 is caused specific from optics connection CCTV camera apparatus 24
Just output image send optical signal and while just produce uplink optical signal in up optical cable 23 its
From optics connection CCTV camera apparatus, output image does not send optical signal for it.For example, due to downlink optical signal
It is transmitted in common to all from optics connection CCTV camera apparatus 24, therefore is sent out except having been received by data
Send the specific output for connecting the device stopping optical signal outside CCTV camera apparatus 24 from optics of license.
If master control server 21 does not send ack signal due to the conflict of the uplink optical signal for receiving,
Then when ack signal is not received within a predetermined period of time, must from optics connection CCTV camera apparatus 24
Optical signal must be resend.In this case, because the transmission speed of optic communication is very fast, therefore weight
New transmission will not very big impact overall transfer speed.
