Embodiment Construction

[0019] refer to figure 1 , a communication method of a virtual watt-hour meter proposed by the present invention, which communicates with a third-party system by establishing a virtual watt-hour meter to send required data to the third-party system.

[0020] The communication method includes the following steps:

[0021] S1. The watt-hour meter classifies the data collected in real time by data type and stores them in different memory addresses.

[0022] The real-time data collected by the watt-hour meter includes: instantaneous active power, instantaneous reactive power, voltage, current, forward active power, reverse active power, etc. These data are stored in different memory addresses after being collected by the power meter, which is convenient Reading of different types of data at any time.

[0023] S2. A virtual electricity meter model is established, and the address of the virtual electricity meter is consistent with the address of the physical electricity meter.

Abstract

The invention discloses a communication method for a virtual electric meter, which transmits desired data to a third party system by establishing the communication between the virtual electric meter and the third party system. The communication method comprises the following steps: S1, classifying data collected by the electric meter in real time according to data types, and respectively storing the data in different memory addresses; S2, establishing a model of the virtual electric meter; S3, deploying an RS485 port as a port of the virtual electric meter; S4, receiving a data collection command transmitted by the third party system, and judging the data collection command; S5, when the data collection command is correct, performing judgment analysis on the data collection command to obtain the information of the data which needs to be collected by the third party system; S6, taking the corresponding data in a memory, and sending the corresponding data to the third party system through the port of the virtual electric meter. The communication method for the virtual electric meter, disclosed by the invention, solves the problem that the electric meter only provides one or two RS485 communication ports, so that the requirement of a plurality of automated systems for collecting the data cannot be satisfied.

Description

technical field [0001] The invention relates to the technical field of intelligent meter reading, in particular to a communication method for a virtual electricity meter. Background technique [0002] In substations (stations), small hydropower stations, thermal power plants, etc., it is often encountered that multiple automation systems need to collect watt-hour meter data, but the current watt-hour meter only provides two RS485 communication ports at most, and a large number of early watt-hour meters Only one RS485 communication port is provided, and the communication ports of these watt-hour meters are not expandable, so that only 1-2 automation systems on site can collect watt-hour meter data, and other automation systems cannot collect data due to lack of ports. Features. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a communication method for a virtual watt-hour meter, which overcomes ...
