Further, the cloud terminal also comprises an information processing unit for centralizing temporary storage networking data and uniformly partitioning management, namely a cloud terminal constructed by a baseband processing unit consisting of a plurality of baseband processing devices, and a large number of information processors and information memories are also arranged in the cloud terminal. The first power distribution cabinet and the second power distribution cabinet are in communication connection with the information processing unit through another mutually independent wireless communication channel, namely two parallel lines are arranged between the first power distribution cabinet and the second power distribution cabinet, the first power distribution cabinet can directly schedule instructions with the second power distribution cabinet, and the information processing unit can also acquire working parameters of any second power distribution cabinet. Typically, the information processing unit is disposed near the location of the first power distribution cabinet, and the information processing unit is disposed between the first power distribution cabinet and the second power distribution cabinet.
Specifically, two mutually independent communication modules are arranged in the first power distribution cabinet and the second power distribution cabinet, namely, the first communication module and the second communication module are arranged in the first power distribution cabinet and the second power distribution cabinet, and the communication modes of the two communication modules are different, for example, loRa communication modules are adopted for communication connection between the first power distribution cabinet and the second power distribution cabinet, and 5G network communication connection is adopted between the first power distribution cabinet, the second power distribution cabinet and the information processing unit; or WiFi communication connection is adopted between the first power distribution cabinet and the second power distribution cabinet, and Bluetooth LE communication modules are adopted between the first power distribution cabinet, the second power distribution cabinet and the base station for communication.
The information processing unit can periodically send a preset scheduling instruction to the second power distribution cabinets, so that working parameters and networking data of each second power distribution cabinet are acquired and stored, and the acquired working parameters are stored in the information processing unit in a partitioning mode, so that the first power distribution cabinet can directionally retrieve the networking data. In the invention, the working parameters of the power distribution cabinet refer to parameter information related to the safety and the use condition of the power distribution cabinet, such as a periodic current change value, a periodic voltage change value, a power factor, an in-box environment temperature and the like.
Particularly, the information processing unit can be used as a standby data segment for data synthesis, and the second power distribution cabinet and the information processing unit are in data transmission through another communication mode, so that the relative distance is relatively short, and the integrity of data is relatively high. The second power distribution cabinet and the information processing unit are in periodic communication, relative data storage is more complete, when the first power distribution cabinet needs to schedule the second power distribution cabinet information, scheduling instructions can be directly sent to the second power distribution cabinet to obtain information, then the obtained information is sent to the information processing unit to conduct data comparison and synthesis, namely, the data in the information processing unit are used as original data, the data sent by the first power distribution cabinet are perfected and adjusted, and the finished data are fed back to the first power distribution cabinet to form latest networking data.
Further, networking data transmitted between the first power distribution cabinet and the second power distribution cabinet comprise running state data, electric energy distribution and protection data, network architecture data and power supply data of the switch cabinets, wherein the acquisition of the network architecture data and the power supply data is used for conveniently optimizing management of a networking network and guaranteeing stability and reliability of power supply.
In this embodiment, the above four types of data may be grouped and separately transmitted through two communication modules, for example: the operation state data, the electric energy distribution and the protection data of the switch cabinet are in a group, the data transmission is carried out through the first communication module, the network architecture data and the power supply data are in a group, the networking data transmission is carried out through the second communication module, and the first communication module and the second communication module carry out the networking data transmission in a communication mode of two different channels, so that good transmission efficiency and independent reliability of the networking data transmission are respectively guaranteed.
In order to ensure the reliability of the transmission of the two communication modules, when the networking data is transmitted, a compression technology can be further adopted at the transmission end to process all networking data or specific networking data, for example: sampling time sequence networking data at one end of a second power distribution cabinet to obtain sampling data of data to be compressed, then carrying out time-frequency domain transformation on the sampling data at one end of a first power distribution cabinet to obtain frequency domain sequence data of the data to be compressed, carrying out truncation processing on the frequency domain sequence data, processing the frequency domain sequence data of the data to be compressed after being truncated by using a trained neural network model to obtain characteristic data of the data to be compressed, and carrying out principal component extraction on the characteristic data of the data to be compressed by using principal component extraction parameters to obtain a compression result, thereby improving the data compression efficiency; and carrying out differential remapping on each field file at one side of the second power distribution cabinet to obtain a base file, a base index file and a difference file corresponding to each field file, and carrying out huffman coding on the base files, the base index files and the difference files corresponding to all the field files to obtain a compressed file, thereby realizing high efficiency of networking data compression and high utilization rate of hardware resources. It should be noted that, in order to realize this function, corresponding information processing modules should be further disposed in the first power distribution cabinet and the second power distribution cabinet to compress and decompress the compressed data.
Specifically, a plurality of remote radio frequency devices are also connected into the information processing unit through the outbound link, so that interval interference is reduced, and network capacity and networking data transmission efficiency are improved. Particularly, the remote radio frequency device only reserves a radio frequency function, and a cooperative multi-point technology is adopted among a plurality of remote radio frequency devices, so that flexible allocation among resources is realized, the utilization rate of the resources is further improved, and the rate of acquiring networking data by the first power distribution cabinet is greatly improved.
It will be appreciated that in a power distribution system, the power distribution cabinets include low voltage power distribution cabinets as well as high voltage power distribution cabinets. High voltage distribution cabinets are typically used to handle 3 to 35kV power systems, mainly for branches and power access to power transmission and distribution lines, while low voltage distribution cabinets typically handle 380V and below power systems. Along with the progress of science and technology, the two generally adopt the cluster networking of many mode to use, and first switch board can be the high-voltage distribution cabinet or low-voltage distribution cabinet promptly, and the second switch board can be high-voltage distribution or low-voltage distribution cabinet, and the combination mode of its cluster depends on specific service environment.

For the low-voltage power distribution cabinet A, the networking information of each of the high-voltage power distribution cabinet 1, the low-voltage power distribution cabinet B, the low-voltage power distribution cabinet C, the low-voltage power distribution cabinet D and the low-voltage power distribution cabinet E can be received, so that the number of the high-voltage power distribution cabinets is 1, the number of the low-voltage power distribution cabinets is 5, namely the high-voltage power distribution cabinets are determined to be used as primary nodes, and the low-voltage power distribution cabinets (including the low-voltage power distribution cabinets) are determined to be used as secondary nodes. Similarly, the same is true for the low-voltage power distribution cabinets B-E, and the description is omitted.
Optionally, the networking information is further used for indicating the location of the power distribution cabinet of the networking information, such as information carrying the location of the power distribution cabinet, such as longitude and latitude coordinates. The method may further comprise: the first power distribution cabinet determines a plurality of low-voltage power distribution cabinets located near the first power distribution cabinet as a power distribution cabinet cluster scheduled by the first power distribution cabinet according to networking information.
When the high-voltage power distribution cabinet 1 needs to directionally schedule the working parameters of a certain low-voltage power distribution cabinet, or when the working parameters cannot be acquired when a certain low-voltage power distribution cabinet is in a disconnection state, a scheduling instruction can be directly sent to the information processing unit, and the designated partition networking data and the working parameters are extracted.
Further, the high-voltage power distribution cabinet 1 can determine that the power distribution cabinet located nearby (such as a distance between the high-voltage power distribution cabinet and the high-voltage power distribution cabinet is smaller than a threshold distance) comprises a low-voltage power distribution cabinet A, a low-voltage power distribution cabinet B and a low-voltage power distribution cabinet C according to networking information, namely, the low-voltage power distribution cabinet A, the low-voltage power distribution cabinet B and the low-voltage power distribution cabinet C are determined to be used as a power distribution cabinet cluster 1 and are scheduled by the high-voltage power distribution cabinet.
And the same applies when the low-voltage power distribution cabinet is used as the first power distribution cabinet.

In order to ensure the reliability of the transmission of the two communication modules, when the networking data is transmitted, a compression technology can be further adopted at the transmission end to process all networking data or specific networking data, for example: sampling time sequence networking data at one end of a second power distribution cabinet to obtain sampling data of data to be compressed, then carrying out time-frequency domain transformation on the sampling data at one end of a first power distribution cabinet to obtain frequency domain sequence data of the data to be compressed, carrying out truncation processing on the frequency domain sequence data, processing the frequency domain sequence data of the data to be compressed after being truncated by using a trained neural network model to obtain characteristic data of the data to be compressed, and carrying out principal component extraction on the characteristic data of the data to be compressed by using principal component extraction parameters to obtain a compression result, thereby improving the data compression efficiency; and carrying out differential remapping on each field file at one side of the second power distribution cabinet to obtain a base file, a base index file and a difference file corresponding to each field file, and carrying out huffman coding on the base files, the base index files and the difference files corresponding to all the field files to obtain a compressed file, thereby realizing high efficiency of networking data compression and high utilization rate of hardware resources. It should be noted that, in order to realize this function, corresponding information processing modules should be further disposed in the first power distribution cabinet and the second power distribution cabinet to compress and decompress the compressed data.
Specifically, a plurality of remote radio frequency devices are also connected into the information processing unit through the outbound link, so that interval interference is reduced, and network capacity and networking data transmission efficiency are improved. Particularly, the remote radio frequency device only reserves a radio frequency function, and a cooperative multi-point technology is adopted among a plurality of remote radio frequency devices, so that flexible allocation among resources is realized, the utilization rate of the resources is further improved, and the rate of acquiring networking data by the first power distribution cabinet is greatly improved.
It will be appreciated that in a power distribution system, the power distribution cabinets include low voltage power distribution cabinets as well as high voltage power distribution cabinets. High voltage distribution cabinets are typically used to handle 3 to 35kV power systems, mainly for branches and power access to power transmission and distribution lines, while low voltage distribution cabinets typically handle 380V and below power systems. Along with the progress of science and technology, the two generally adopt the cluster networking of many mode to use, and first switch board can be the high-voltage distribution cabinet or low-voltage distribution cabinet promptly, and the second switch board can be high-voltage distribution or low-voltage distribution cabinet, and the combination mode of its cluster depends on specific service environment.
The networking mode between the first power distribution cabinet and the second power distribution cabinet is explained below. The power distribution cabinet participating in networking comprises: the high-voltage power distribution cabinet 1, the high-voltage power distribution cabinet 2, the low-voltage power distribution cabinet A, the low-voltage power distribution cabinet B, the low-voltage power distribution cabinet C, the low-voltage power distribution cabinet D and the low-voltage power distribution cabinet E are the first power distribution cabinet, and the low-voltage power distribution cabinet A-the low-voltage power distribution cabinet E are the second power distribution cabinet. The power distribution cabinets respectively carry networking information of the respective identifications. For the high-voltage power distribution cabinet 1, the networking information of each of the high-voltage power distribution cabinet 2, the low-voltage power distribution cabinet A, the low-voltage power distribution cabinet B, the low-voltage power distribution cabinet C, the low-voltage power distribution cabinet D and the low-voltage power distribution cabinet E can be received, so that the number of the low-voltage power distribution cabinets is determined to be 5, the number of the high-voltage power distribution cabinets is determined to be 2 (including the high-voltage power distribution cabinets per se), namely the high-voltage power distribution cabinets are determined to be used as primary nodes, and the low-voltage power distribution cabinets are determined to be used as secondary nodes. The high-voltage power distribution cabinet 2 is the same as the high-voltage power distribution cabinet 1.
For the low-voltage power distribution cabinet A, the networking information of each of the high-voltage power distribution cabinet 1, the high-voltage power distribution cabinet 2, the low-voltage power distribution cabinet B, the low-voltage power distribution cabinet C, the low-voltage power distribution cabinet D and the low-voltage power distribution cabinet E can be received, so that the number of the high-voltage power distribution cabinets is determined to be 2, the number of the low-voltage power distribution cabinets is determined to be 5, namely the high-voltage power distribution cabinets are determined to be used as primary nodes, and the low-voltage power distribution cabinets (including the low-voltage power distribution cabinets) are determined to be used as secondary nodes. Similarly, the same is true for the low-voltage power distribution cabinets B-E, and the description is omitted.
