Development system of interoperability electricity communication protocol

Abstract

The invention discloses a development system of an interoperability electricity communication protocol, which comprises an application data processing unit, an IEC62056 communication protocol stack module, a frame buffer zone and an information buffer zone, wherein the IEC62056 communication protocol stack module comprises a physical layer, a link layer and an application layer, data received by the physical layer are put into the frame buffer zone, an information part in the frame buffer zone is transmitted to the information buffer zone, the application layer decodes a service part in the information buffer zone, the decoded service part is processed by the application data processing unit, the returned data are coded by the application layer and sent to the frame buffer zone; the application data processing unit decodes, processes and codes the data part in the information buffer zone and sends the data part to the frame buffer zone; and the link layer codes a frame to obtain an integral frame to be stored in the frame buffer zone and sent by the physical layer. The invention can furthest save singlechip resources and ensure that an electricity meter of a small-capacity singlechip can carry out intercommunication operation according to an IEC62.56 protocol statute.

Description

technical field [0001] The invention relates to a development system for an interoperable electric meter communication protocol, in particular to a development system for the electric meter communication protocol of the IEC62056 communication in the electric meter industry. Background technique [0002] The current development direction of electric meters is automatic meter reading and intelligent services. At present, in the field of electric meters in China, the national standards DL / T645-1997 and DL / T645-2007 are the main ones. There is little reference to the advanced foreign interoperable IEC62056 protocol. Facing the increasing demand for smart meters abroad and With the demand for protocol interoperability, more and more countries are tending to the IEC62056 protocol, and the market prospect is quite broad. [0003] However, the technology of IEC62056 is complicated and the content is rich. In order to reduce the cost of the current meters, the space of the single-ch...

Problems solved by technology

[0003] However, the technology of IEC62056 is complicated and the content is rich. In order to reduce the cost of the current meters, the space of the single-chip computer is generally small, so that the IEC62056 protocol communication cannot be realized in the existing meters.
