And a single host can limit the view angle for observing the light effect, so that the light debugging of a scene is inconvenient. The large control loop is needed by the professional stage dimming control console, the standard PC computer system is used for processing a large amount of control data to meet the requirement of high-speed data processing with large capacity by the existing large loop dimming control console (more than 2000 loops), so that the computer system based on the PC system is used as a main processing unit and is required to be managed by an operating system, such as DOS, windows and the like, meanwhile, storage devices such as a hard disk and the like are also configured, the system is too complex and expensive, the risk of virus invasion system breakdown exists, site performance is interrupted, and system faults are caused by the conditions that the existing PC system is provided with movable memory strips, CPU, hard disk, ISA and PCI slots, transportation, moisture, dust, connector oxidization and the like.

fig. 2 is a schematic diagram of a system architecture in the ethernet-based dimming data synchronization method of the present invention. Fig. 3 is a schematic diagram of a master-slave architecture in the ethernet-based dimming data synchronization method of the present invention. As shown in fig. 2 and 3, a control end cluster connected to the same ethernet switch is provided, and the ethernet switch is connected to and controls the working state of the lamp group through the decoder group. The control end cluster comprises a host 2 and a plurality of slaves 31, 32 … … N, and each host and/or slave comprises a processor module 21, an input module 22 connected with the processor module 21, a storage module 23, a network module 24 and a memory module 25. The network module is connected with the Ethernet switch 1, the memory module establishes a tree-shaped data sub-table based on the connection relation of the lamps in the lamp group, and each node in the tree-shaped data sub-table stores the illumination data group of a lamp node.

Decoder bank 41: the data in the network is decoded to DMX512 data and output to the light fixture group 42.

The above devices constitute an ethernet (master-slave, decoder) responsible for the computation of the data and the transmission in the ethernet.

As shown in FIG. 4, the master and the slave can be independently operated and controlled, the master is one, the slave can be multiple, the master and the slave are in a logical relationship rather than a physical relationship, and a user can self-control the definition of the master and the slave. The master-slave machine at least comprises a business logic, a calculation unit and a streaming unit in terms of business functions. The data input unit refers to that after receiving data through devices such as an electric push rod, an encoder, a mouse, a keyboard, a touch screen and the like, the service logic and calculation unit processes the service logic and calculates according to the input data such as a certain operation instruction, the calculated data result is delivered to the fluidization unit, the fluidization unit performs fluidization processing such as streaming through an xml stream format, and finally the data result is transmitted to the network through the output unit.

The data table adopts the C++ object-oriented concept design, derives various kinds from the basic class step by step, and stores the data in class member objects. The object of each class is a "node" in the tree data table. After the program is started, the service units of the master and slave create the data table in the memory and change the data table continuously according to the service change. The changes in the data table are divided into: three types of addition/deletion/numerical change. The addition is to add an object, namely a node, and the deletion is to delete the object, and the numerical change refers to the change of the numerical value of the member object.

Fig. 6 is a schematic diagram of data interaction performed by a master and slave in the ethernet-based dimming data synchronization method of the present invention.

Combining rules: the member objects of each class are provided with 'time members', the specific time for updating the numerical value of the object is recorded, the member objects of each class are provided with 'rule members', and the processing is carried out according to the numerical value of the 'rule members' during merging. The values of the "rule members" are as follows: locking, taking maximum value, taking minimum value, last time covering, etc. The time member and the rule member are used as operation authority attributes of the objects, and can be placed in class members, or a authority attribute data table can be independently generated, wherein the time member and the rule member of each object are recorded in the authority attribute data table, and each object is associated by referring to an object pointer in the data table. And judging whether the object of the data table of the requesting party is changed or not, performing data adjustment on the unlocked object, and updating the unlocked object into the data of the latest time, the data of the maximum value or the data of the minimum value according to the preset service requirement. If the local object is locked, it is not processed.

In the above merging method, it can be seen that the master and slave machines can work independently and synchronize through the form of a data table, and the data table adopts the concept of a c++ class object, so that the data table is hierarchical, and the objects and the data of each hierarchy are attached with "authority attribute", which specifically refers to the division of the working authorities: the host A is responsible for controlling the lamps 1 to 100, the uppermost class object which is responsible for controlling the lamps can be set to be locked, and the rest slaves can not control the lamps.
