A Communication Method for Virtual Watt-hour Meter

Abstract

The present invention proposes a communication method for a virtual watt-hour meter, which sends required data to a third-party system by establishing a virtual watt-hour meter to communicate with a third-party system; the communication method includes the following steps: S1. The collected data is classified according to the data type and stored in different memory addresses respectively; S2, establishing a virtual watt-hour meter model; S3, configuring an RS485 port as a virtual watt-hour meter port; S4, receiving data collection sent by a third-party system Command and judge; S5. When the data collection command is correct, judge and analyze the data collection command to obtain the information of the data that the third-party system needs to collect; S6. Call the corresponding data in the memory and send it through the virtual watt-hour meter port to third-party systems. The communication method of a virtual electricity meter proposed by the invention overcomes the problem that the electricity meter only provides one or two RS485 communication ports and cannot meet the needs of multiple automation systems for data collection.

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. Function. 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 ...

Examples

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.
