Abstract
The utility model relates to a stage light signal coding and decoding system, comprising a stage light controller, a network coding module, a first power carrier coding and decoding module, a stage light fixture control module, a network decoding module, and a second power carrier coding and decoding module. The stage light controller, the network coding module, and the first power carrier coding and decoding module are sequentially connected. The first power carrier coding and decoding module is connected with a power line. The stage light fixture control module, the network decoding module, and the second power carrier coding and decoding module are sequentially connected. The second power carrier coding and decoding module is connected with another power line. An RS485 communication line is no longer provided between the stage light controller and a stage light fixture, and the alternating-current power lines are directly used to conduct power carrier transmission of multiple paths of DMX512 signals, so that the wiring is very convenient.
Description
Technical field
The utility model relates to light of stage signal codec system.
Background technology
In the light of stage application, the DMX512 signal that a desk lamp light device routine needs working power and RS485 to drive.In the inconvenient signal system wiring of some occasion stage light controller and light fixture distance, or signal system deploys, and follow-uply wants to increase the DMX circuit and bothers very much.
The utility model content
The purpose of this utility model is to propose a kind of light of stage signal codec system, and it can solve the problem of wiring trouble.
In order to achieve the above object, the technical scheme that the utility model adopts is as follows:
Light of stage signal codec system, it comprises stage light controller, network code module, the first power carrier coding/decoding module, stage lamp control module, network decoding module and the second power carrier coding/decoding module, stage light controller, network code module and the first power carrier coding/decoding module are connected successively, the first power carrier coding/decoding module is connected with power line, stage lamp control module, network decoding module and the second power carrier coding/decoding module are connected successively, and the second power carrier coding/decoding module is connected with power line.
Preferably, described network code module has one and sends first of address module is set for carrier signal is set; Described network decoding module has one, for second of carrier signal receiver address is set, module is set.
Preferably, the first power carrier coding/decoding module is connected with the network code module by a network signal line, and the network code module is connected with stage light controller by a DMX512 holding wire.
Preferably, the second power carrier coding/decoding module is connected with the network decoding module by another network signal line, and the network decoding module is connected with the stage lamp control module by another DMX512 holding wire.
The utlity model has following beneficial effect:
No longer include the RS485 communication line between stage light controller and stage lamp, directly by AC power cord (being power line), carry out electric force carrier transmission multichannel DMX512 signal, connect up very convenient, can transmit multichannel DMX512 signal by a 220V power line, abandoning a conventional RS485 holding wire can only transmission of one line DMX512 signal simultaneously.
The accompanying drawing explanation
The structural representation of the light of stage signal codec system that Fig. 1 is the utility model preferred embodiment.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further.
As shown in Figure 1, a kind of light of stage signal codec system, it comprises stage light controller, network code module, the first power carrier coding/decoding module, stage lamp control module, network decoding module and the second power carrier coding/decoding module.
Stage light controller, network code module and the first power carrier coding/decoding module are connected successively, the first power carrier coding/decoding module is connected with power line, stage lamp control module, network decoding module and the second power carrier coding/decoding module are connected successively, and the second power carrier coding/decoding module is connected with power line.Concrete, the first power carrier coding/decoding module is connected with the network code module by a network signal line 1, and the network code module is connected with stage light controller by a DMX512 holding wire 2.The second power carrier coding/decoding module is connected with the network decoding module by another network signal line 3, and the network decoding module is connected with the stage lamp control module by another DMX512 holding wire 4.
The network code module of the present embodiment has one, for first of carrier signal transmission address is set, module is set; The network decoding module has one, for second of carrier signal receiver address is set, module is set.
The course of work of the present embodiment is as follows:
The first power carrier coding/decoding module and the second power carrier coding/decoding module access the 220V AC power supplies by power line, by first arrange module, second arrange module to sending address, receiver address is arranged, so that control signal can send to corresponding light fixture.Stage light controller is exported control signals to the network code module by DMX512 holding wire 2, the network code module is modulated into network signal by control signal and sends to the first power carrier coding/decoding module, the first power carrier coding/decoding module is modulated into network signal carrier signal and sends to the second corresponding power carrier coding/decoding module by power line, the second power carrier coding/decoding module is decoded into carrier signal network signal and exports to the network decoding module, the network decoding module is decoded rear output DMX512 signal to the stage lamp control module to network signal again, the stage lamp control module just can be controlled corresponding light fixture according to the DMX512 signal.
It should be noted that, network decoding module, the second power carrier coding/decoding module, stage lamp control module all can be integrated in stage lamp.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and the distortion all should belong to the protection range of the utility model claim within.
