Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.
See Fig. 1, a kind of double loop lamp light control system of the invention, including controlling terminal 1, for playing video, controls
Terminal 1 is connected with DVI distributor 2, and the vision signal multiplexing that controlling terminal 1 exports is divided into the road N and exported by DVI distributor 2,
Middle N is the even number more than or equal to 2, and the output end of DVI distributor 2 is separately connected the receiving end of fiber optical transceiver 3, fiber optical transceiver
3 receiving end is connected to the transmitting terminal of fiber optical transceiver 3 by optical fiber, and the transmitting terminal of fiber optical transceiver 3 is connected respectively to master control
Device 4 processed, master controller 4 and 5 communication connection of sub-controller, can be set interchanger between master controller 4 and sub-controller 5,
Video signal transmission to sub-controller 5, sub-controller 3 with lamps and lanterns communication connection, are controlled lamps and lanterns and play view by master controller 4 respectively
Frequently, sub-controller 5 is equipped with two groups of transmission ports, and two groups of transmission ports are connected respectively to different master controllers 4 and make each point
Device 5 is controlled to be connected by two bars transmission links simultaneously.
Specifically, sub-controller can be arranged to the sub-controller group that several grades are connected, every grade of sub-controller group includes
At least one sub-controller, when any sub-controller group is provided at least two sub-controllers, with its upper level, next fraction
The transmission port for the sub-controller that controller group is connected is equipped with an input port and two output ports, input port are used for
The vision signal that upper level sub-controller group is sent is received, one of output port is used to send the vision signal received
Next stage sub-controller group is given, another output mouth is used to for the vision signal received to be sent to another sub-control at the same level
Device processed.
Specifically, DVI distributor exports after the vision signal that controlling terminal exports is copied into two parts when N takes 2；Work as N
When taking the even number more than or equal to 4, vision signal extension is first divided into N/2 parts, then after being copied into two parts by DVI distributor respectively
Output.
Application of the above-mentioned double loop lamp light control system in heterotypic high-rise building outdoor lighting, the high level is given below
The height of irregular building is more than 400 meters, since its height is too long, video is divided into upper and lower two parts transmission and respectively by different
Master controller controls lamps and lanterns by sub-controller and plays out.
As shown in Fig. 2, Fig. 2 given the wherein two-part vision signal from fiber optical transceiver to sub-controller be
System block diagram, the system block diagram of the vision signal of remaining two-part fiber optical transceiver to sub-controller is identical therefore omits comprising
Controlling terminal 1, for playing video, vision signal extension is first divided into 2 parts and does two by the equipment for using model RT9802
Divide transmission, then exports after being copied into two parts by DVI distributor respectively to the receiving end of fiber optical transceiver 3, fiber optical transceiver 3
Receiving end connects the transmitting terminal of fiber optical transceiver by optical fiber, and the transmitting terminal of fiber optical transceiver 3 is connected respectively to master controller 4,
The equipment that master controller 4 uses RTP_8000, master controller 4 are connected to sub-controller, and sub-controller 3 is communicated with lamps and lanterns respectively
Connection, control lamps and lanterns play video, and sub-controller 5 is equipped with two groups of transmission ports, and two groups of transmission ports are connected respectively to different
Master controller 4 connects each iversion controller 5 by two bars transmission links simultaneously；
Sub-controller includes multistage sub-controller, and each grade of sub-controller should flexibly be directed to the LED illumination point of different layers
The sub-controller of quantity demand setting different number control lamps and lanterns；
When a certain grade sub-controller is only provided with one since the LED illumination point by controlling is few, in input port reception
The vision signal received is sent to next stage sub-controller by the vision signal that level-one sub-controller group is sent, output port
Group；
When a certain sub-controller group is due to more than the LED illumination point by controlling therefore when peer is provided with multiple, with its upper level,
The transmission port for the sub-controller that next stage sub-controller group is connected is equipped with an input port and two output ports, input
Port is used to receive the vision signal of upper level sub-controller group transmission, and one of output port is used for the video that will be received
Signal is sent to next stage sub-controller group, and another output mouth is used to for the vision signal received to be sent to the another of peer
One sub-controller, other sub-controllers at the same level only use its input port, are respectively used to receive two-path video signal.
In the present embodiment, sub-controller uses two kinds of models of RTP_DUAL_X6D and RTP_DUAL_X8, is owned by two groups
RJ45 mouthfuls of One In and Two Out are used as transmission port, are the LED since the LED type of the lamps and lanterns of connection is different using two kinds of sub-controllers
Density is different, therefore the control protocol inside the LED of different height is also just different, therefore two kinds of controllers are mainly according to lamps and lanterns
Depending on type.
The vision signal of controlling terminal 1 is drawn by DVI line, is accessed DVI distributor, is divided into upper and lower part from top to bottom
Divide and upper and lower part from top to bottom has four parts, the reception of four output incoming fiber optic transceivers of DVI distributor altogether in this way
It holds, and is connected to the transmitting terminal of fiber optical transceiver using optical fiber, this is to extend DVI signal so as to long distance transmission video
Signal, four fiber optical transceivers give tetrameric video signal transmission to four master controllers, and each master controller believes video
Number transmission of video is carried out to sub-controller by surpassing five class cables, each sub-controller has the hundred Broadcoms work of two groups of One In and Two Out
For transmission port, the one of every group is into the network interface for being respectively connected to two upper and lower master controls, and every group of two paths of signals gone out is all the way
Down all the way up, it is achieved that each sub-controller is connected by two bars transmission links, if wherein disconnected all the way
Another way will be alternate video source, it is achieved that double loop, when in a wherein circuit main, sub-controller because factor can not be resisted
It breaks down when occurring the case where causing lamps and lanterns not show normally, video will automatically continuously be played by another way, will not influence
The display of lamps and lanterns, entire lamp light control system can influence to continue normal play video section with uncontrolled device system operation irregularity
Mesh.
