In the lamp control system that the utility model provides, master controller and distributor include the ethernet physical layer chip with a plurality of passages, realized the monitoring of light fixture state, be convenient to the fault point of the system of searching, largely simplified the management and the maintenance of system, and the employing of data feedback channel, down going channel data transfer mode makes system have the advantage that automatic frequency is adjusted.
Description of drawings
Fig. 1 is the structure chart of the lamp control system that provides of the utility model embodiment;
Fig. 2 is the schematic diagram of the LED lamp locker data transfer mode that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Among the utility model embodiment, light-emitting diode (Light Emitting Diode, LED) light fixture of controlling as lamp control system, transfer of data adopts multichannel Ethernet data communication mode, and data channel is divided into down going channel and data feedback channel, master controller sends the instruction of lighting or extinguishing by down going channel to the LED light fixture, the LED chip for driving then by data feedback channel with the abnormal state feedback information of LED light fixture to master controller.
Fig. 1 shows the structure of the lamp control system that the utility model embodiment provides, and for convenience of description, only shows the part relevant with the utility model embodiment.
Please refer to Fig. 1, whole lamp control system comprises master controller, distributor (as D1, D2, D3, D4, D5, D6) at least, this lamp control system is connected with a plurality of LED light fixtures by distributor, and with control LED light fixture, wherein the LED light fixture comprises LED lamp and driver module.Between master controller and the distributor, transfer of data between distributor and the distributor all adopts the ethernet communication mode, master controller and distributor include ethernet physical layer chip and the programmable logic device with a plurality of passages, and the passage of ethernet physical layer chip is set to two kinds of down going channel and data feedback channels, wherein, the network packet that the down going channel of master controller by its ethernet physical layer chip will include information such as current operational order and driving parameters transfers in each distributor, distributor is finished the decoding of network packet by programmable logic device, and by the down going channel of ethernet physical layer chip current operational order and driving parameters are transferred in the light fixture chip for driving, chip for driving is lighted according to current operational order control LED lamp or is extinguished; When LED light fixture abnormal state, chip for driving by its data feedback channel with detected abnormal data message transmission to the connected distributor, distributor is the network packet that is suitable for the Ethernet transmission with the packing data that receives by programmable logic device, and network packet is transferred to master controller by the data feedback channel of ethernet physical layer chip, gather all system informations by master control, generation system situation form, for example when LED short circuit occurs or opens circuit, can feed back this information to master controller by above-mentioned path, thus convenient fault point of searching system.If just because when the frequency departure of drive signal is big so that the LED light fixture does not work, can feed back abnormal information to master controller by above-mentioned path, reset Control Parameter by master control, adjust driving frequency, light until the LED light fixture, the employing of multichannel ethernet physical layer chip simultaneously also makes the system data transmission rate improve greatly.
When system need control the LED light fixture of a greater number, can also a plurality of subsystem element be coupled together by router, by the unified control of master controller, whole lighting system layout is flexible, as shown in Figure 1, master controller passes through distributor (D7) successively to the parameter of current operational order of the control of LED light fixture and setting, router, distributor (D4, D5, D6) input to the chip for driving of LED lamp module after, and the abnormal information of chip for driving feedback is passed through distributor (D4 successively, D5, D6), router, distributor (D7) inputs to master control, router comprises ethernet physical layer chip and the programmable logic device with a plurality of passages equally, and the transfer of data of router and distributor still adopts the Ethernet data communication mode.
Among the utility model embodiment, the ethernet physical layer chip in master controller, distributor, the router is 100M ethernet physical layer chip or 1G ethernet physical layer chip, and the data transmission bauds in the whole system is improved; And because the quantity of system descending channel transfer is greater than the data feedback channel data quantity transmitted, consideration for the optimization system resource distribution, recommend to adopt data feedback channel and down going channel dissymmetrical structure in the ethernet physical layer chip, and the down going channel message transmission rate is greater than the data feedback channel message transmission rate, for example for 4 path 10 0M PHYAltima AC104-QF chips, down going channel 300M can be set, data feedback channel 100M.
For large-scale lighting system, in order to improve the problem of the long Distance Transmission signal attenuation of high-frequency signal, each LED lamp locker adopts data transfer mode as shown in Figure 2, be connected with inverter T1 and T2 respectively at each LED light fixture two ends, high-frequency signal transmits with low level signal between arrival LED light fixture, become high level behind the process inverter T1 earlier when needing the driving LED light fixture, and become low level after through inverter T2 from the signal of LED light fixture output, to be reduced in the signal attenuation that arrives before next LED light fixture.
In the utility model, lighting system is selected for use strong, the fireballing master control of disposal ability to be made as core the LED light fixture is carried out Real-time Monitor Management, whole lighting system message transmission rate improves greatly, not only can support flash program making mode, can also reach the purpose of program production methods such as support parameterization produces automatically, screen interception by executive software.
In sum, in the lamp control system that the utility model embodiment provides, master controller, distributor and router include 100M or 1G ethernet physical layer chip and the programmable logic device with a plurality of passages, realized the light fixture status detection, be convenient to the fault point of the system of searching, the management and the maintenance of system have largely been simplified, the system data transmission speed also is improved, and the employing of asymmetric data feedback channel, down going channel data transfer mode makes system have the advantage that automatic frequency is adjusted; The employing of inverter has reduced the decay of high-frequency signal between the LED light fixture, each distributor bringing onto load quantity is increased greatly, reduced the field wiring difficulty to a certain extent, and the lamp control system that has fast data transmission, master controller that processing capacity is powerful supports multiple program making mode, makes programme content more rich and varied.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
