Embodiment Construction

[0036] The technical solution of the present invention is further elaborated in conjunction with the accompanying drawings and embodiments.

[0037] as Figures 1 through 3 As shown, the communication method of the present embodiment, to achieve the communication of the intelligent energy meter and the load identification module, the basic framework of the smart energy meter is multi-core modular, comprising a measurement core responsible for the basic metering, responsible for the management of the whole meter management core, and for extending the function module to the peripheral serial device interface SPI. The extended function module includes, but is not limited to, the upstream communication module, the load identification module, the multi-table collection module, the ordered charging module and the power quality analysis module; the full name of SPI is Serial Peripheral Interface, that is, the peripheral serial device interface, the working mode is divided into two types: ...

Abstract

The present invention proposes an SPI-based communication method and system between an intelligent electric energy meter and a load identification module, and adopts three measures: adding feedback signal lines, packet transmission, and error retransmission; The feedback channel of the electric energy meter; on the one hand, sub-packet transmission reduces the probability of error, on the other hand, it reduces the amount of retransmitted data; through the signal line and sub-packet transmission function, it provides the possibility for the error retransmission function, and the retransmission mechanism Adding it greatly improves the reliability of transmission and the continuity of waveform sampling.

Description

Technical field [0001] The present invention belongs to the field of intelligent energy meter communication technology, particularly relates to a SPI-based intelligent energy meter and load identification module communication method and system. Background [0002] The first draft of the specification of the next generation of intelligent energy meters released in the new release clarifies that the basic framework of the future intelligent energy meters is "multi-core modularity", "multi-core" that is, the measurement core and the management core, the measurement core is responsible for the basic measurement function, requiring high reliability and long life; the management core is responsible for the management tasks of the whole meter, including cost control, display, external communication, data recording, etc. "Modularity" refers to the extended function module of the energy meter in accordance with the unified interface type, including the upstream communication module, the l...
