Dynamic intelligent meter reading method and system

Abstract

The invention discloses a dynamic intelligent meter reading method and system, which belong to the technical field of intelligent power grids. The method comprises the steps of: building a meter file,a collection task and a collection scheme of each electric energy meter, and calculating the total number n of electric meter data items needing to be read in a current period according to the collection task and the collection scheme, obtaining the maximum meter reading waiting reply time t1 according to the current period remaining time t2 and the meter reading remaining times (n-i-j) obtainedin the task execution frequency, according to the maximum meter reading waiting reply time t1, performing meter reading processing on each data item of the current electric energy meter, storing the successfully read data items into a successful data list, and storing the unsuccessfully read data items into a failed data list, and estimating the longest waiting time again after any time of readingis completed. The reading time of the data items is prolonged or shortened through the number of the current remaining data identifiers which are not successfully read, and all the data items needingto be read of all the electric energy meters can be ensured to be normally and successfully read.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a dynamic smart meter reading method and system. Background technique [0002] In our daily life, we cannot do without electricity. According to the official data released by the State Grid Grid, the annual electricity sales are as high as 4.2361 billion kwh, and such huge data statistics are collected from tens of thousands of electricity consumption information collection terminals. Acquisition, and as a power consumption information collection terminal, it will face all meter users under a station area or branch road. [0003] In the power system, the number of meters managed by an electricity information collection terminal is adjusted to local conditions. In some areas, there are even thousands of meters. Due to the complex environment of the site and the continuous improvement of the success rate of meter reading by various power supply companies, the The success rate ...

Problems solved by technology

[0004] However, at present, the mainstream meter reading method of most terminal manufacturers is to fix the reading order of the electric energy meter according to the fixed measurement point number or other similar attributes that can be used for distinction. Influenced by factors such as incomplete practices, this will lead to a low terminal collection rate, and other electric energy meters that cannot be collected normally will use manual copying to obtain data, which will inevitably increase the cost of on-site operation and maintenance.
