Electric energy data collection method and device

Abstract

The embodiment of the invention provides an electric energy data collection method and device. A concentrator calculates a collection task of each collector according to the collection needs and issues the collection tasks to a plurality of collectors to enable the collectors to issue collection messages to an electric energy meter according to the collection tasks to collect electric energy data of the electric energy meter; when a collection time is achieved, the concentrator sends a collection command to each collector to enable each collector to pack the multiple collected electric energy data into a data block and upload the data block, then receives the data block and processes the data; so that the process that the data is collected from the electric energy meter is separated from the process that the data is reported to the concentrator, meanwhile, in the process that the data is collected from the electric energy meter, a plurality of collectors carry out meter reading concurrently without mutual inference; and in the process that the data is reported to the concentrator, the electric energy data is packed into the data block, the data block is upward sent to the concentrator through a frame of message, the whole interaction time is shortened, and the whole collection efficiency is improved.

Description

technical field [0001] The invention relates to the field of low-voltage electric energy collection, in particular to an electric energy data collection method and device. Background technique [0002] When the concentrator collects the electric energy data of the electric energy meter, generally only one data item of one electric energy meter can be collected for each frame of message. Assuming that there are m electric energy meters in a station area, and each electric energy meter has n data items to be collected, the concentrator needs to send m×n frame collection messages. Assuming that it takes t1 for the concentrator to send the message to the collector for receiving, it takes t2 for the collector to send the message to the energy meter for receiving it, and it takes t2 for the energy meter to send the message to the collector for receiving it. The concentrator takes t1 to finish receiving, and the concentrator needs to spend 2×m×n×(t1+t2) to complete all the collect...

AI Technical Summary

Problems solved by technology

[0004] 1. Generally, the concentrator can only collect one data item per frame of message, and cannot collect multiple data items as required, and the efficiency is low

[0005] 2. The concentrator’s delivery of the collection message and the collector’s forwarding of the collection message cannot be carried out at the same time, that is, the concentrator needs to wait for the electric energy meter to return the electric energy data before sending a new frame of collection message

Therefore, the channel utilization rate is low, resulting in a slow overall reading speed
