Abstract
The invention discloses an electric quantity synchronous processing-based intelligent electric energy meter dual core communication method. A master SPI management core and a slave SPI metering core are connected via an SPI interface; a communication frame between the management core and the metering core consists of a frame start character, a control code, a data field length, a data field, a checking code and an ending character; the data field comprises data markers of electric energy meter data items that need to be read; the intelligent electric energy meter dual core communication method is advantageous in that an SPI communication protocol is built between the electric energy meter management core and the metering core, the communication frame is free from address redundancy, the electric energy meter data items that are needed are read according to the data markers, communication between the management core and the metering core is enabled to be simple and highly efficient, and electric quantity metering of the management core and the metering core can be synchronized.
Description
Technical field
The present invention relates to a kind of means of communication, especially relate to a kind of intelligent electric energy meter twin-core based on electricity synchronization process
Between the means of communication.
Background technology
Along with the progress of the Internet science and technology, daily life is changed stepwise.Wherein, the development of electrical equipment day especially
Crescent is different, and power consumption increases substantially, and the electricity charge occupy the ratio of running cost and are significantly increased, and the accuracy for electricity metering is wanted
Ask and stepping up.Thus, the IR46 standard-required that OIML issues: " legality measurement part (electric energy metrical number
According to and clock data) not by other some effects ", twin-core intelligent electric energy meter arises at the historic moment, by metering core be responsible for measure power consumption,
Management core is according to the electric energy measurement data of metering core and the clock data record electricity charge, it is therefore desirable to sets up data between twin-core and leads to
Letter, but the common means of communication have address redundancy, affect communication speed, it is difficult to reach the electricity synchronization process between twin-core.
Summary of the invention
The technical problem to be solved is to provide between a kind of intelligent electric energy meter twin-core based on electricity synchronization process
The means of communication, communication frame saves address so that the communication between management core and metering core is the simplest, efficient, with
Reach to manage the synchronization process of electric quantity metering between core and metering core.
The present invention solves the technical scheme that above-mentioned technical problem used: a kind of Intelligent electric based on electricity synchronization process
The means of communication between energy table twin-core, its main SPI management core is connected by SPI interface with from SPI metering core, management core and metering core
Between communication frame be made up of start-of-frame, control code, data field length, data field, check code and end mark, described data field
In comprise the Data Identification of electric energy meter data item that requirement is read.
Compared with prior art, it is an advantage of the current invention that to establish SPI communication between electric energy meter management core and metering core
Agreement, does not has address redundancy in communication frame, the electric energy meter data item needed for reading according to Data Identification, makes management core and metering
It is that point-to-point communication is simpler, efficient between core, thus reaches to manage the synchronization process of electric quantity metering between core and metering core.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail.
This preferred embodiment is the means of communication between a kind of intelligent electric energy meter twin-core based on electricity synchronization process, including meter
Amount core and management core, (Serial Peripheral Interface, serial peripheral connects by SPI interface for management core and metering core
Mouthful) connect, management core is main SPI, and metering core is to include from the signal of communication between SPI, management core and metering core: clock signal
SCLK, from equipment enable signal CS, main frame input/from machine output signal MISO, main frame output/from machine input signal MOSI.Pipe
Communication frame between reason core and metering core is by start-of-frame, control code, data field length, data field, check code and end mark structure
Become, communication frame format such as following table.Make between twin-core, to form point-to-point communication, thus save address redundancy, reduce chip operation
Amount, communication is the most succinct, efficiently.
