Description

Lighting control device using protocol conversion and addressing type repeater and its control method

The present invention is proposed for compatibility of lighting control devices that are released in various ways, and in particular, a main controller using a communication protocol for lighting control and a plurality of slaves (receivers) connected thereto standardize the protocol through a protocol conversion unit, It relates to a lighting control apparatus using a protocol conversion and address assignment repeater for allocating a virtual address and a control method therefor. That is, the present invention relates to a lighting control device and a control method therefor using a protocol conversion and address assignment repeater that can be connected to any main controller / slave around the world that complies with the protocol.

In general, a lighting control device is a device that connects a light source dimming module and a light source console in hardware/software.

[0008] In particular, DMX512, which is most often used as a lighting control device, is an international standard for digital multiplex signals, DMX512 is a method of connecting one controller (controller) to multiple receivers, and DMX512 data is two wires Transmits data at a speed of 250kbps using a standard RS-485 transmission device through (DATA+ & DATA-). Accordingly, each receiving device must determine a “starting channel number (hereinafter, Start Address)” to respond to it.

1 is a detailed timing chart of DMX512 Protocol. This protocol includes reset status, start code, and data transmission for 512 bytes (8bit DATA x 512). Each receiving device counts 8-bit data sequentially from the incoming channel after the Start Code, and if their Start Address matches the value, they accept the data and output it. In the case of receiving devices that comply with the DMX512 Protocol, each Start Address is required to receive accurate data from the controller. A receiver that receives only one 8-Bit Data and uses it as one output is called a 1-channel, and a receiver that receives three 8-Bit Data and uses it as three outputs is called a 3-channel receiver.

In the case of conventional receiving devices, any one of three methods is used to designate a Start Address.

First, there is a manual type that adds a rotary switch, a DIP switch, a key, a display, etc. in hardware and reads the values connected to the I/O pins of the CPU and sets them as their own Start Address.

In this case, in the case of a one-channel receiver that complies with the DMX512 protocol, the user must operate up to 512 switches, and in the case of a three-channel receiver, 170 switches. Also, it is very cumbersome because it has to be installed in order during construction (construction), and setting this process manually also takes a long time and is a cumbersome process. Also, if the wrong Start Address is specified by mistake, the operation will be different from the intention with the user.

Second, a method to store the Start Address by developing a device such as a separate address input device and to download the Start Address after setting the Start Address when designing the first firmware. Users cannot easily change the Start Address. , even if it is possible to change it, a separate equipment is required. In addition, it becomes a very cumbersome task because it is necessary to find the number of each receiver and install them in order during construction (construction).

Third, there is no need for manual operation by the user, and it can be changed automatically at any time, so the start code is unconditionally designated as 000 or 001. It is an intelligent automatic address allocation method, but this method is not standardized. There is a problem that it is not compatible with the controller (controller).

In the related prior art, Patent Registration No. 10-0551955, Patent Registration No. 10-0934991, Patent Registration No. 10-1062874, and Patent Registration No. 10-0841900, the control device automatically Since it was not possible to receive specific codes such as DATA and power supply signals that can recognize addresses, it was impossible for each manufacturer and developer to standardize each other.

The present invention is to solve the above problems, and is proposed for compatibility with lighting control devices that are released in various ways. An object of the present invention is to provide a lighting control apparatus using a protocol conversion and address assignment repeater that standardizes a protocol through a conversion unit and allocates a virtual address, and a control method thereof.

That is, as an embodiment of the present invention, it is possible to connect with any main controller/slave in the world that conforms to the DMX512 standard protocol, so that a standardization device conforming to the DMX512 standard protocol is implemented.

A protocol conversion and address assignment type repeater according to the present invention comprises: a main for generating a lighting control signal; a program unit for generating lighting control data in software; a repeater receiving the lighting control data generated from the program unit and performing a master role; It is characterized in that it comprises a slave for driving each lighting device according to the lighting control data transmitted from the repeater.

In addition, the control method of the addressable repeater compatible with the lighting control device according to the present invention includes the steps of applying power to the main and each slave of the lighting control device (S10); Initial setting step (S20) such as I/O and PORT; Step (S30) for the control unit to determine whether the input DATA corresponds to a normal protocol, or whether it is specific data other than a normal protocol; In the case of a normal protocol, the step of giving a virtual address (S40); Transmitting the virtual address given to the data signal of the lighting control device to the slave 30 (S50); In the case of an abnormal protocol, a virtual address is given (S40) after the pre-step (S31) of first converting to a standardized protocol, and the data signal of the standardized lighting control device and the assigned virtual address are transferred to the slave (30). It is characterized in that the transmitting step (S50); sequentially proceeds.

The lighting control device and its control method using the protocol conversion and addressing repeater according to the present invention standardize the protocol through the protocol conversion unit to a plurality of slaves (receivers) connected to the main controller using the protocol to comply with the standard protocol It is possible to connect with any controllers around the world, and it has the effect of extending the number of lighting devices controlled by the main controller by allocating a virtual address.

A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In general, when transmitting a signal on a digital communication line, the signal is attenuated as the transmission distance increases. At this time, the reproduction repeater that regenerates the attenuated transmission signal and transmits it again is called a repeater, and a bit repeater that receives bits from a segment (LAN unit) and simply reproduces the signal electrically without any processing and passes it to the next segment It is divided into Bit Repeater and Buffered Repeater, which can combine LANs of different speeds because it has a memory buffer, and can construct a fast and economical LAN because it does not analyze packets. In the present invention, by applying the repeater, a lighting control apparatus and a control method thereof using a protocol conversion and address assignment repeater are proposed.

2 is a block diagram showing a schematic driving method of a lighting device using a protocol conversion and addressing repeater according to the present invention, and FIG. 3 is a schematic diagram of an embodiment implementing the same.

A lighting device using a protocol conversion and address assignment repeater according to the present invention includes a main 10 that generates a lighting control signal, a program unit 11 that generates lighting control data by software, and the program unit 11 ) receives the lighting control data generated from the repeater 20 to perform a master role, and a slave 30 for driving each lighting device according to the lighting control data transmitted from the repeater 20. .

At this time, the main 10, the program unit 11, the repeater 20, and the slave 30 are connected to each other by wire, and in particular, the slave 30 that directly controls the repeater 20 and the plurality of lighting devices is wired. Alternatively, various communication interfaces such as wireless, for example ZigBee, BlueTooth, Wi-Fi, TCP/IP, RS485, RS232, etc. can be used.

In particular, the repeater 20 includes an input protocol conversion unit 22 that converts the data signal transmitted from the main 10 into a compatible protocol, and a virtual address that gives a virtual address transmitted to the slave 30 . It is configured to include an (Adress) assigning unit 23 and an amplifying unit 24 for amplifying a data signal including the converted protocol signal and a virtual address.

The repeater 20 is a device that converts a protocol of a wired signal, assigns a virtual address to the slave 30, and transmits it to the slave 30. The repeater 20 includes a controller 21 for controlling the entire operation. and a communication unit 26 using a communication interface such as TCP/IP, ZigBee, BlueTooth, Wi-Fi, RS485, and RS232 for wireless transmission to the slave 30 may be provided.

In addition, the repeater 20 receives the protocol of the slave 30, and converts the protocol transmitted from the main 10 back to the protocol of the slave 30 and outputs the protocol conversion unit 25 at the output stage may be added. there is.

The biggest problem of the prior art is the compatibility of different protocols. In the present invention, standardization is possible through the protocol converters 22 and 25 provided in the repeater 20, and detailed techniques for protocol conversion are The detailed description of the protocol is described in the reference manual of the product released by the company, and through this, the process of standardizing according to the reference manual of the slave to be used. Since it is a well-known technology in the art, the detailed description below will be omitted.

In general, in the case of stage LED lighting devices, more than 10 slots are allocated to one lighting device for RED, GREEN, BLUE, color control, and motors to control the direction of lighting. Although the number of possible lighting devices is limited, in the present invention, virtual addresses are assigned by the repeater 20 to control more lighting devices.

On the other hand, in an embodiment of the present invention, in the conventional DMX receiver, the output of the main 10 is input to the RS485 IC of the input terminal of the first receiver (slave) to control the lighting device, and the RS485 IC of the output terminal again Since it is operated in such a way that it is transmitted to the second receiving device (an adjacent slave) through the same protocol, there is a problem in that it does not operate normally. A new idea of converting to a standardized protocol was proposed.

Hereinafter, the control method of the present invention will be described in detail through the flowchart of FIG. 4 .

First, when the power application step (S10) to the main 10 and each slave 30 is performed, an initialization setting step (S20) such as I/O and PORT is performed.

Thereafter, the control unit 21 determines whether the input DATA conforms to a normal protocol or is specific data other than a normal protocol (S30).

If it is an abnormal protocol, a virtual address is assigned (S40) after the pre-step (S31) of converting to a standardized protocol first, and the standardized data signal and the assigned virtual address are transmitted to the slave (30) ( S70).

Also, in the case of a normal protocol, a virtual address is assigned (S40).

In particular, the control unit 21 of the repeater 20 receives the protocol of the slave 30 (S50), and determines whether the protocol of the output of the repeater 20 and the protocol of the slave 30 is the same (S60). In this case, it moves to step (S70), and if it is not the same, the step (S61) of re-converting according to the protocol of the slave 30 by the output protocol conversion unit 25 is added.

Then, the virtual address assigned to the data signal of the lighting control is transmitted to the slave 30 (S70).

In an embodiment of the present invention, in the step (S31), in case of different protocols, the protocol is automatically converted by the conversion table based on the reference manual provided by the manufacturer of the main 10 through the input terminal protocol conversion unit 22. It can be configured to convert. In this case, the conversion table is arranged in advance so that a specific code used in each different protocol can be matched with a standardized code, and the conversion time can be significantly reduced.

Although the present invention has been described in detail through specific examples, this is for the purpose of describing the present invention in detail, and the present invention is not limited thereto, and modifications thereof are made by those skilled in the art within the technical details of the present invention. However, it is clear that improvement is possible.
