example 1

[0126] like Figure 8 As shown in FIG. 1 , it is a comparison chart of the amount of data transmitted by using the data fusion method and not using the data fusion method under a single-phase connection mode provided by the embodiment of the present application. It can be seen from the figure that for a large-scale photovoltaic communication network that needs to collect a large amount of inverter data, the amount of data generated when data fusion is used to transmit data is smaller than when data fusion is not used, especially when there are many carrier communication nodes , will greatly reduce the amount of carrier communication data.

example 2

[0128] like Figure 9 As shown in the embodiment of the present application, there is a comparison chart of the amount of data transmitted by using the data fusion method and not using the data fusion method under a three-phase connection mode provided by the embodiment of the present application. Under the same network scale, assuming that the communication nodes in the network are evenly distributed on each phase, it can be seen from the figure that for the same network scale, distributing the communication nodes in the network on three phases can effectively reduce the The amount of data generated by the power line carrier communication on each phase, and the data amount of the carrier communication is significantly reduced when the data fusion method is used compared with the unfused method.

[0129] The following are method embodiments of the present application, which can be used to implement the system embodiments of the present application. For details not disclosed in ...

Abstract

The invention provides a data fusion system and method based on power line carrier communication. The system comprises a main node, a fusion node and an independent node. The independent node is connected with the main node or connected with the main node through the fusion node; and the fusion node is connected with the main node, or is connected with the main node through the independent node orthe fusion node. The independent node is used for collecting first target data of a first preset type, and determining core data of the first target data. The fusion node is used for collecting second target data of a second preset type, receiving core data of the first target data, splitting the second target data, and determining fused data according to the split second target data and the coredata of the first target data. The main node is used for receiving the fused data. Fusion in the data transmission process is realized, the data transmission space is saved, and the data transmissionaccuracy is ensured.

Description

technical field [0001] The present application relates to the communication field, in particular to a data fusion system and method based on power carrier communication. Background technique [0002] With the gradual improvement of photovoltaic power generation technology, a large number of distributed photovoltaic power generation systems have been put into production and life. Correspondingly, how to collect real-time data in the photovoltaic power generation system has also become an important research issue in the field of communication. [0003] At present, the method of power line carrier communication is mainly used to solve the problem of collecting real-time data in photovoltaic power generation systems. Specifically, the method regards each broadband carrier module as a communication node, gathers the data of the communication nodes in a certain area to a main communication node, and then transmits it. However, the existing power line carrier communication method...
