A self-learning meter reading method for electricity consumption information of electric power users

Abstract

The invention discloses a self-learning meter reading method of a power user information collection terminal. When the collection terminal collects a certain electric energy meter data item for the first time, it collects all data items according to the requirements of the collection system, establishes a self-learning file, and During the collection process, records are made according to the support of each data item by the electric energy meter. In the next round of collection process, first read the self-learning file and collect according to the support of the data item in the self-learning file. If the current energy meter does not support the data item, it will automatically skip and no longer collect. The invention marks the support of the current electric meter for data items by establishing a self-learning folder, shortens the collection time of the electricity consumption information collection terminal, improves the collection success rate, improves the timeliness of collection, and saves system resources.

Description

technical field [0001] The invention relates to the field of smart grids, in particular to a method for reading electric energy meter data by a power user's electricity consumption information collection terminal. Background technique [0002] The power user electric energy data acquire system is a system for collecting, processing and real-time monitoring of electricity consumption information of power users, realizing automatic collection of electricity consumption information, measurement abnormality monitoring, power quality monitoring, power consumption Power analysis and management, relevant information release, distributed energy monitoring, information interaction of intelligent electrical equipment and other functions. [0003] Electric energy data acquire terminal (electric energy data acquire terminal) is a device for collecting electricity information at each information collection point, referred to as the acquisition terminal. It is a device that can realize t...

Problems solved by technology

[0007] When the terminal collects the current energy meter data, if the energy meter does not reply to the unsupported data items, the terminal will think that there is interference with the current message sending and receiving, which leads to the reply data from the energy meter not being received normally, and will try to resend and wait for the timeout period, such as normal A request-response interaction will be completed within 1s, but if the energy meter does not reply, the terminal will resend 3 times, each time waiting for a timeout of 1.5s (if it is a carrier channel, it will wait for a timeout of 45s), which will inevitably cause the current energy meter to The collection time is too long, resulting in the data items that need to be collected behind the current energy meter cannot be collected in time, and the data timeliness is not good

Regardless of whether the energy meter replies or does not reply, the repeated collection of data items not supported by the energy meter by the terminal will cause the collection time of some electric energy meters to be too long, and more than one electric energy meter is collected on the same collection channel, especially the carrier channel. Thousands of electric energy meter data, which will cause the collection of all electric energy meter data cannot be completed within one collection cycle, affecting the success rate of collection

[0008] In addition, the resources of the embedded system are limited, and repeated collection of energy meters that do not support data items will cause unnecessary CPU and memory resource consumption of the energy meter and the collection terminal, and will cause the carrier module to have no time to learn and optimize routing.

If it is a carrier channel, it will cause unnecessary interference to the power quality of residents
