Description

DMX decoder with RDM function
Technical field
The utility model belongs to LED light regulating technology field, and in particular to a kind of DMX decoder with RDM function.
Background technique
DMX512 is the common control protocol of recreation lamp optical arena, with its simplicity, reliability and flexibility rapidly at Preferred agreement in the case of allowing for fund.All kinds of products for having DMX agreement are met the tendency of as a result, can be by the DMX of standard It is required data packet and output that data packet analysis, which unpacks,.It, can be by the unified control of the lamps and lanterns of unlike signal in the market by DMX agreement System, master control is without being concerned about that controlled lamp type can achieve the desired results.Compare the lamp light control system of traditional analog, DMX control Though there are many benefits for system processed, due to the one-way and continuity of its data frame, it will bring to the construction maintenance in later period all It is mostly inconvenient.Such as: adjustment and expansion, the lamps and lanterns damage of engineering lamps and lanterns device location are replaced etc., in view of these situations, need to construct Personnel readjust the position i.e. address DMX according to scheme drawing one by one, if system is by the equipment group of thousands of DMX agreements up to ten thousand At such modification will be time-consuming and laborious engineering.
The appearance of RDM agreement will compensate for these deficiencies, and the agreement is run under the existing DMX network platform, It hardly needs and increases any cost, it is only necessary to increase the agreement on product software.By the agreement, can remotely set Set and browse DMX relevant parameter (address DMX, lamps and lanterns state, equipment running status etc.).Such as: certain requirement of engineering expand or more Change replacement and node location has been installed, user can be directly by the position of RDM master control remotely modifying respective nodes or in convenient position It sets and directly increases new node without modifying to computer room or high-altitude.This will substantially increase construction efficiency, reduce cost.
DMX decoder with RDM function is to realize the necessary configuration of above-mentioned purpose.There are more production classes both at home and abroad at present The product of likelihood decoder device, such as ENTTEC (Australia), eldoLED (Holland), Shanghai Euchips Industrial Co., Ltd..Mesh Before, there are still various problems for existing product, such as: the disadvantages of poor compatibility, interface complexity, less varieties, not comprehensive RDM protocol block, Constructed system is likely to occur the case where being unable to operate normally.
Utility model content
The problem of based on mentioned in background technique, the utility model proposes a kind of DMX decoder with RDM function, Its particular technique content is as follows:
A kind of DMX decoder with RDM function, including shell and positioned at the installation hanging plate of shell back side, the shell It is equipped with for obtaining the RDM/DMX input interface of upstream RDM or DMX signal, for transmitting RDM or DMX signal backward RDM/DMX output interface, and the connecting terminal for connecting DC power supply and LED light, the circuit part within the shell Including processor, RS485 bus module, power tube output module and DC-DC conversion circuit, the processor is integrated with or connects There are digital serial port, PWM timer and memory, the processor passes through the digital serial port and the RS485 bus module phase Even, and if main line pwm control signal generated by PWM timer export to power tube output module, the memory is used to deposit Store up the UUID information of the parameter and content and the machine that are arranged from RDM master control, the input terminal of the DC-DC conversion circuit, output End is connected with the connecting terminal respectively.
The utility model beneficial effect is: providing DMX and RDM decoding control, solves the control of LED light photosystem simultaneous and ask Topic is realized according to the conventional RDM setting to processor and receives RDM master information, and can correctly reply the inquiry of RDM master control Instruction possesses store function to the parameter and content of RDM master control setting, and timely responds to the parameter and content of RDM master control setting, It is powered on after power-off, does not lose the parameter and content of RDM master control setting;One RDM master control following can hang more and have RDM function DMX decoder, RDM master control can collect the information of these decoders, and can modify the related ginseng of these decoders as needed Several and content, brings convenience to project installation.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the DMX decoder with RDM function of the utility model.
Fig. 2 is the working principle diagram of the DMX decoder with RDM function of the utility model.
Fig. 3 is the utility model for lighting system networking schematic diagram.
Specific embodiment
As follows in conjunction with attached drawing 1 to 3, application scheme is further described:
A kind of DMX decoder with RDM function, including shell 1 and positioned at the installation hanging plate 2 of 1 back side of shell, the shell Body 1 be equipped with for obtain upstream RDM or DMX signal RDM/DMX input interface 3, for backward transmit RDM or DMX signal RDM/DMX output interface 4, and the connecting terminal 5 for connecting DC power supply and LED light, the bottom surface setting of the shell 1 Groove 10, the connecting terminal 5 hiding are set in the groove 10, the circuit part within the shell 1 include processor 61, RS485 bus module 62, power tube output module 63 and DC-DC conversion circuit 64, the processor 61 are integrated with or are connected with Digital serial port 611, PWM timer 612 and memory 613(EEPROM), the processor 61 by the digital serial port 611 with The RS485 bus module 62 is connected, and if being exported by the generation main line pwm control signal of PWM timer 612 defeated to power tube Module 63 out, the memory 613 are used to store the UUID information of parameter and content and the machine from RDM master control setting, institute The input, output end for stating DC-DC conversion circuit 64 is connected with the connecting terminal 5 respectively, the DC-DC conversion circuit 64 Being adapted to input voltage range is DC 12-24V, generates and includes at least DC 12-24V output, DC 5V output.
The difference of decoder and the common decoder without RDM function with RDM function is that RDM master can be received Information is controlled, and can correctly reply the inquiry instruction of RDM master control, storage function is possessed to the parameter and content of RDM master control setting Can, and the parameter and content of RDM master control setting are timely responded to, it is powered on after power-off, does not lose the parameter and interior of RDM master control setting Hold.
The RS485 bus module, which possesses, sends and receivees function control pin, when being configured to receive mode, receives RDM Master information;When being arranged to sending mode, the inquiry instruction of RDM master control is replied;It is adjusted to receive according to the timing of RDM agreement Or sending mode, achieve the purpose that two-way communication.
It is that above-mentioned preferred embodiment should be regarded as application scheme embodiment for example, all with application scheme thunder Same, approximate or technology deduction, replacement, improvement for making based on this etc., are regarded as the protection scope of this patent.
