Centralized metering data acquisition method and device and electronic equipment

Abstract

The invention provides a centralized measurement data acquisition method and device and electronic equipment, which can reduce the production cost and improve the data sampling quality. The method comprises the following steps: acquiring multiple groups of initial data by utilizing multiple data acquisition subboards, and preprocessing the initial data to generate first intermediate data; forwarding the plurality of groups of first intermediate data to a data acquisition mainboard through a data exchange chip; the data acquisition mainboard performs integration processing on the multiple groups of first intermediate data to generate second intermediate data; forwarding the second intermediate data to the central metering board through the data exchange chip; and the central metering board determines metering data according to the second intermediate data and performs data integration management. The device comprises a central metering board, a data exchange chip, a data acquisition main board and a plurality of data acquisition auxiliary boards. The electronic equipment comprises a memory, a processor and a computer program which is stored on the memory and can run on the processor to execute the centralized measurement data acquisition method.

Description

technical field [0001] One or more embodiments of the present application relate to the technical field of digital automation, and in particular to a method, device and electronic equipment for collecting centralized metering data. Background technique [0002] Traditional centralized metering devices for digital input generally include a CPU board and multiple metering boards. Multiple metering boards each have independent sampling, calculation, metering and other functions. 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 higher requirements for the CPU performance of the metering board, which will increase the material cost of the metering board, and the meter...

Problems solved by technology

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 higher requirements for the CPU performance of the metering board, which will increase the material cost of the metering board, and the metering board A large number of uses will further increase the cost of the entire device; in this design, each metering board will transmit the metering data to the CPU after completing the metering function, and then the CPU will manage and communicate the data. The amount of metering data itself is relatively large. There is a great pressure on the internal communication bandwidth, and the internal communication pressure will limit the sampling rate and the number of access intervals, which will inevitably compromise the sampling rate and the number of access intervals, which limits the performance of the centralized metering device and is not conducive to the centralized metering device.
