Abstract
The utility model discloses a decoding device based on a DMX512 protocol, which comprises a main controller, a peripheral circuit, a DMX512 signal input port and a DMX512 signal output port, wherein the main controller comprises an EEPROM (electrically erasable programmable read-only memory), the peripheral circuit comprises a 485 level switch circuit, a power supply circuit and an LED drive circuit, and is connected with the main controller through a lead, and the DMX 512 signal input port and the DMX512 signal output port are connected with the 485 level switch circuit through the lead. Aiming at the defect of setting the address by adopting a dial switch, the EEPROM is adopted for setting the address, thus having the advantages of saving source and being convenient for operation; and the DMX512 signal output port is adopted, so that the device has the output function of the DMX 512, and the device can be used for decoding and sending the control signal based on the DMX 512 protocol.
Description
Technical field
The utility model relates to decoding device, more particularly, relates to a kind of decoding device based on the DMX512 agreement.
Background technology
Lighting source LED light fixture has advantages such as long, low in energy consumption, lucuriant in design variable, safety of life-span, low-voltage power supply, is subjected to attracting attention of common people gradually in illumination and decoration field.In order to make LED light reach dynamically colorful variation effect, LED lighting control system is arisen at the historic moment, and wherein the lamp light control system based on the DMX512 agreement is used more and more widely, increasing control appliance correspondingly occurred.General DMX512 decoding device need cooperate outside toggle switch to realize control to corresponding LED light fixture, yet use toggle switch can take the more resource of controller, be unfavorable for the equipment mass production, cost performance is also lower, and need the address be set manually, make troubles to use.
The utility model content
The purpose of this utility model is to overcome the deficiency that method that existing decoding device based on the DMX512 agreement uses toggle switch that the address is set brings for system time and operation, a kind of decoding device based on the DMX512 agreement is provided, and it has saves resource, easy to operate advantage.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of decoding device based on the DMX512 agreement, it comprises master controller, peripheral circuit, DMX512 signal input and DMX512 signal output, described master controller comprises EEPROM, described peripheral circuit comprises 485 level shifting circuits, power circuit and led drive circuit, it is connected with master controller by lead, and described DMX512 signal input is connected 485 level shifting circuits with the DMX512 signal output by lead.
The beneficial effects of the utility model are: can use and write the location device and write the address for the EEPROM module of master controller inside by the DMX512 signal input, thereby realize the control of LED light fixture signal; Described decoding device is realized the transmission of signal and the cascade of system according to the actual instructions for use modulation DMX512 signal of LED light fixture and by the output of DMX512 signal output; The utility model has been saved the shared resource of control device, has brought convenience to practical operation, has to save resource, easy to operate advantage.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
At first see also Fig. 1 the utility model structure chart, illustrate a kind of decoding device and comprise master controller 1, peripheral circuit 3, DMX512 signal input 4 and DMX512 signal output 5 based on the DMX512 agreement.Described peripheral circuit 3 comprises 485 level shifting circuits 7, power circuit 8 and led drive circuit 9, and they all are connected with master controller 1 respectively by lead 10.Described DMX512 signal input 4 is connected 485 level shifting circuits 7 with DMX512 signal output 5 by lead 10.Described led drive circuit 9 connects LED light fixture 6 by lead 10.Described master controller 1 comprises EEPROM2, it can cooperate writes the location device and writes the address by DMX512 signal input 4, export at least three road pwm signals then, realize the control of LED light fixture 6 by led drive circuit 9, and by being used the variation effect of controlling LED light fixture 6 with the DMX512 apparatus for transmitting signal.
When the utility model specifically used, power circuit 8 provided electric energy for described decoding device, and master controller 1 is according to the pwm signal of the address output appropriate address of EEPROM2, and came driving LED light fixture 6 by led drive circuit 9, realized the variation effect of light fixture.Write the address that the location device can be reset EEPROM2 by external, realize the change of address code easily.
During concrete the use, described transitive relation based on signal in the decoding device of DMX512 agreement is as described below:
The DMX512 signal is through DMX512 signal input 4 accesss to plant, enter master controller 1 by 485 level shifting circuits 7, described master controller 1 use control logic by with EEPROM2 in the data that are provided with relatively, the output control signal is come driving LED drive circuit 9, thus control LED light fixture 6; Master controller 1 modulation DMX512 signal is by 485 level shifting circuits 7, from 5 outputs of DMX512 signal output simultaneously.
