Description
Technical Field
The present invention relates to the field of data communication technologies, and in particular, to a method for clustering a plurality of physical devices into a logical device.
Background
At present, conversion devices such as ArtNET and sabn based on control protocols of the ethernet are independent from each other, devices in the same network need to be configured independently in the use process, and various state data in the devices also need to be checked independently. When the device is used in a large amount, equipment parameters are required to be configured one by one, running state data are required to be checked one by one, and the working efficiency is too low and inconvenient. In order to be able to perform unified management, additional dedicated headquarters and other devices can be purchased, but this is certainly an increase in the cost.
The prior art needs to purchase special total control equipment, has high cost, otherwise needs to configure the equipment one by a user, checks the running state of the equipment one by one, and is inconvenient to collect the equipment data. When the consistency requirement on the working behavior of the equipment is needed, the equipment cannot be configured uniformly, the working parameters are manually input, and the defects of error and leakage and the like are easy to occur.
Therefore, there is a need for an operation mode that is simple to operate, convenient to use, low in cost, and configured in a centralized manner, so that multiple physical devices are automatically clustered into one logical device, and the usability of the product is improved.

Further, the device adjusting itself according to the modification data includes:
the device judges whether the modified data belongs to the data block of the device;
if yes, the working behavior of the self is correspondingly adjusted according to the modified data; if not, only data is stored, and the self behavior is not required to be changed.
Furthermore, the data synchronization between the devices is realized through a synchronous data mechanism.
Further, the synchronous data mechanism is formed by multicast sharing of multicast addresses.
Further, the data block is composed of a plurality of data record formats.
Further, the data recording format is used for recording the working state of the corresponding subunit of the self equipment and the information of the controlled lamp hung under the subunit.

Detailed Description
The invention will be further described with reference to the accompanying drawings, in which the directions of fig. 1 are used.
As shown in fig. 1-3, in the method for clustering a plurality of physical devices into a logical device according to an embodiment of the present invention, a plurality of devices are provided, which can be set automatically according to performance, so as to facilitate an illustration of how to implement the clustering of a plurality of devices into a logical device by the method.
A multicast address is pre-agreed between the devices, the multicast address usually selects a local link multicast address, after the device A, B, C is started, the device A, B, C sends its own data block a, data block B and data block C to the multicast address, the device A, B, C sends its data block to the multicast address and simultaneously receives the data blocks of the other two devices, that is, the device a sends the data block a to the multicast address and simultaneously receives the data block B and the data block C, so that the device a has the data of the other two devices, that is, through the data blocks of the other devices on each device after multicast, as shown in fig. 2, the device a has not only the data block a, but also the data block B and the data block C, and the devices B and C also have the data of the other devices; if the data of three devices need to be changed, only the data block is required to be modified on any device, and the data after modification can be synchronized through a synchronous data mechanism, namely, the data of the device B is modified on the device A, the device B can receive the modified data at the same time, and the device C can also receive the modified data to the device B at the same time; if the data of the device C is to be modified, the device a may also be modified, and the device B may also receive the data modified by the device C, i.e. the device a may serve as a data modification center, and the device B, the device C, or other devices may serve as data modification centers.
In this embodiment, one device must act as both a receiver and a sender. Under the support of multicast technology, as long as a device agrees with a fixed multicast address in advance (can select a local link multicast address), after the device is started, the device sends a data record to the fixed multicast address, and the data record can be received by other similar devices in the same Ethernet, namely, the other devices can sense that a new device joins the cluster, and then the other devices send the data record to the fixed multicast address, so that the just joined device can obtain complete global data, and the original device in the cluster can also obtain a latest global data.
The synchronous data mechanism is formed by multicast sharing of multicast addresses, so that data sharing among all devices is realized, each device judges whether the modified data belong to the device according to a data block, the data block is formed by a plurality of data records, each data record corresponds to a subunit of the device one by one, and the data records are used for recording the working state of the corresponding subunit and the information of all controlled lamps connected to the subunit. For example, the equipment A is provided with five subunits, the data block A is provided with five data records, and the five data records record the working states of the five subunits and the detailed information of the controlled lamps hung under the five subunits.
The data record is provided with a device identifier, a subunit number, a time stamp, detailed data and a check code, and the device judges the shared data through the data record and records the modified data.
The device identifier generally refers to a network card MAC address of the device, and indicates which device the data record belongs to, and the length is fixed; when modifying data on any device, other devices can receive the modified data at the same time, but need to judge whether the modified data belongs to the device itself, if the data is modified to be the data on the device, the device makes a corresponding reaction with the modified data; if not, no care is taken.
The subunit number is used for recording the unified numbers of all the subunits of all the devices in the whole cluster range, and the length is fixed.
The time stamp is used for modifying the time of the self equipment data record, and the equipment data are synchronously combined with each other by referring to the value to make a trade-off, and the length is fixed.
The detailed data are used for recording the working state of the subunit and the controlled lamp information thereof in detail, the length is not fixed, and the length information is contained in the data item so as to carry out data analysis.
The check code is used for ensuring the correctness of the data and checking the whole data record.
If no data record is set, the three devices A, B, C only have own data blocks, and only can modify the own settings in one device, if the data of the three devices are to be modified, the data of the three devices can be modified respectively, so that the efficiency is low and the inconvenience is high. After multicast, the data on each device can be synchronously shared, each device is provided with a data record, the shared data is judged by the data records to make corresponding changes, the data records correspond to the subunits one by one, and the subunits are divided into the same functional modules in one device in terms of logic, so that the granularity is smaller. According to the characteristic, the number of the subunits can be overlapped through a data synchronization mechanism among the devices, so that a plurality of devices are automatically clustered into one logical device physically, and the usability of products is improved.
In the working process of the equipment, as long as the data record changes, the action of sending the data record to the multicast address can be triggered no matter the working state of the sub-equipment is changed due to the modification of a user, so that the data synchronization among the equipment is realized. From the user's perspective, the data interactions between the devices are transparent. When a new device joins the cluster, the data records corresponding to the device sub-units are synchronized to each device in the cluster, the number of sub-units in the cluster increases and these newly added sub-units can be configured on any device. Therefore, the batch management of the equipment can be realized without additionally purchasing special total control equipment, and the cost is reduced.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
