Description

Technical Field

[0002] Traditional centralized metering devices for digital quantity input generally include a CPU board and multiple metering boards. Multiple metering boards each have independent sampling, calculation, metering and other functions, and each metering board is independent of each other. The CPU board is only responsible for data management, human-computer interaction and communication. Because the metering board needs to independently complete the collection, calculation and metering functions, it has high requirements for the data processing capability of the metering board, which inevitably has high requirements for the CPU performance of the metering board, which will increase the material cost of the metering board. In addition, the number of metering boards used is relatively large, which will further increase the cost of the entire device. In this design, after each metering board completes the metering function, it transmits the metering data to the CPU, and then the CPU manages and communicates the data. The amount of metering data itself is relatively large, which puts great pressure on the internal communication bandwidth. The internal communication pressure will limit the sampling rate and the number of access intervals, and will inevitably compromise on the sampling rate and the number of access intervals, which limits the performance of the centralized metering device and is not conducive to the market promotion of the centralized metering device.

[0045] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0046] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of the present application should be understood by people with ordinary skills in the field to which the present disclosure belongs.

[0047] The present application scheme is described below in conjunction with specific embodiments.

[0048] In one aspect, an embodiment of the present application provides a centralized metering data collection method.

[0049] like Figure 1 As shown, a centralized metering data collection method provided by one or more optional embodiments of the present application includes:

[0050] S1: using a plurality of data acquisition sub-boards to collect a plurality of groups of initial data, pre-processing the plurality of groups of the initial data respectively, and generating a plurality of groups of first intermediate data.

[0051] The initial data may include periodic sampling (SV) data of each interval process layer in the digital substation. The data acquisition sub-board may receive the interval process layer SV data collected in the digital substation using a data interface. A plurality of data acquisition sub-boards respectively collect SV data of different interval process layers.

[0052] S2: The plurality of data acquisition sub-boards send the plurality of groups of the first intermediate data to the data exchange chip, and the plurality of groups of the first intermediate data are forwarded to the data acquisition main board by using the data exchange chip.

[0053] The data exchange chip is used to forward data from the data acquisition sub-board to the data acquisition main board, which can ensure the rapid transmission of large amounts of data, and the multiple groups of first intermediate data of multiple data acquisition sub-boards do not interfere with each other, thereby ensuring the accuracy of data transmission.

[0054] S3: The data acquisition mainboard integrates and processes multiple groups of the first intermediate data to generate second intermediate data.

[0055] The data acquisition main board can integrate multiple groups of first intermediate data from different digital acquisition sub-boards, that is, integrate the data information content from different interval process layers of the digital substation, so as to facilitate subsequent transmission to the central metering board for centralized metering calculation.

[0056] S4: The data acquisition main board sends the second intermediate data to the data exchange chip, and uses the data exchange chip to forward the second intermediate data to the central metering board.

[0057] The digital exchange chip is also used for output transmission between the digital acquisition main board and the central metering board to ensure data transmission rate and accuracy.

[0058] In some optional embodiments of the present application, the data exchange chip is a gigabit exchange chip. Accordingly, gigabit Ethernet is used to realize data communication between the data acquisition sub-board and the data exchange chip, between the data acquisition and the data exchange chip, and between the central metering board and the data exchange chip. Compared with the large amount of data transmitted, the data transmission network is guaranteed to have sufficient margin to support faster transmission of a larger amount of data.

[0059] S5: The central-level metering board determines metering data according to the second intermediate data, and performs data integration management on the second intermediate data and the metering data.

[0060] Multiple data acquisition sub-boards are used to collect multiple sets of initial data, and the data acquisition main board is used to summarize and integrate the data. The central metering board then performs unified calculation, metering and data management. In this way, multiple data acquisition boards (including the data acquisition main board and the data acquisition sub-board) are only used to realize data collection and handling functions, which greatly reduces the data processing capacity of the data acquisition board and reduces the production cost from the overall system structure. The data exchange chip is used to transmit data between the data acquisition main board, the data acquisition sub-board and the central metering board, which can support the transmission of larger data volumes, thereby greatly reducing the pressure of data communication within the system, reducing the restrictions on the data sampling rate and the amount of access data, improving the sampling rate and sampling accuracy, and optimizing the data sampling quality.

[0061] like Figure 1 As shown, in a centralized metering data collection method provided by one or more optional embodiments of the present application, the method of collecting multiple groups of initial data using multiple data collection sub-boards includes:

[0062] Utilizing the multiple optical ports on the data acquisition sub-board to receive multiple basic data items;

[0063] The initial data is determined by combining a plurality of the basic data items.

[0064] In some optional embodiments of the present application, the number of data acquisition sub-boards used can be flexibly set according to actual conditions, and the number of optical ports set in each data acquisition sub-board can also be flexibly adjusted. This approach can effectively meet the flexibility requirements of data acquisition.

[0065] like Figure 2 As shown, in a centralized metering data collection method provided by one or more optional embodiments of the present application, the preprocessing of the multiple groups of initial data respectively to generate multiple groups of first intermediate data includes:

[0066] S201: Determine the frame format of the initial data according to the optical port communication protocol corresponding to the optical port.

[0067] S202: Parse the initial data according to the frame format to determine first parsed data corresponding to the initial data.

[0068] S203: performing frame conversion on the first parsed data according to a preset data exchange protocol to generate the first intermediate data.

[0069] When data is transmitted between the data acquisition sub-board and the data exchange chip, communication transmission can be performed according to a preset data exchange protocol to ensure the security and accuracy of data transmission.

[0070] In a centralized metering data collection method provided in one or more optional embodiments of the present application, the step of performing frame conversion on the first parsed data according to a preset data exchange protocol to generate the first intermediate data includes:

[0071] The first parsed data is compressed, and frame conversion is performed according to the data compression result to generate the first intermediate data.

[0072] The data acquisition sub-board also compresses the first parsed data when framing the first parsed data, which can greatly reduce the amount of internal data transmission, thereby further improving the data transmission network margin.

[0073] like Figure 3 As shown, in a centralized metering data collection method provided by one or more optional embodiments of the present application, the data collection mainboard integrates and processes multiple groups of the first intermediate data to generate second intermediate data, including:

[0074] S301: parsing the first intermediate data to generate second parsed data corresponding to the first intermediate data;

[0075] S302: resample the second parsed data to determine sampling data corresponding to the second parsed data.

[0076] S303: sorting and integrating the plurality of groups of the sampling data to generate the second intermediate data.

[0077] The data acquisition mainboard analyzes multiple groups of the first intermediate data and then performs sampling and sorting processing to generate second intermediate data. This method can ensure the orderliness of the integrated second intermediate data and reduce data redundancy.

[0078] In a centralized metering data collection method provided in one or more optional embodiments of the present application, the central-level metering board determines metering data according to the second intermediate data, including:

[0079] performing data parsing on the second intermediate data to determine data content of the second intermediate data;

[0080] A data metering rule corresponding to the second intermediate data is determined according to the data content, and the metering data is determined by calculation based on the second intermediate data according to the data metering rule.

[0081] In a centralized metering data collection method provided in one or more optional embodiments of the present application, after the central metering board determines the metering data according to the second intermediate data, the method further includes:

[0082] sending the second intermediate data and the metering data to the data exchange chip, and using the data exchange chip to send the second intermediate data and the metering data to a display device;

[0083] The display device visually displays the second intermediate data and the measurement data.

[0084] The central metering chip may include a multimedia data interaction (MMI) interface, and the second intermediate data and the metering data may be forwarded to a display device (such as a liquid crystal display) through the data exchange chip for visual display through the MMI interface. The visual display of the second intermediate data and the metering data facilitates the analysis of the data as a whole.

[0085] It should be noted that the method of the embodiment of the present disclosure can be performed by a single device, such as a computer or a server. The method of the present embodiment can also be applied in a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present disclosure, and the multiple devices will interact with each other to complete the described method.
