Problems solved by technology

[0003] The statistical results show that 71% of the access requests focus on 15%-28% of the data for accessing massive power consumption information data. However, the existing big data retrieval methods do not take into account the ubiquity of power consumption information This kind of data access feature directly uses the existing big data retrieval method, which will restrict the speed of power consumption information data retrieval

Embodiment 1

[0041] see figure 1 , Embodiment 1 of the present invention provides a data retrieval method for electricity consumption information, including:

[0042] Step S1: Construct a massive power consumption information database by using multiple pieces of power consumption information data; count the accumulated retrieval times of the electricity consumption information data, and construct a cache using the electricity consumption information data whose cumulative retrieval times meet the cumulative retrieval threshold;

[0043] Step S2: According to the retrieval request, look up the power consumption information data corresponding to the retrieval request in the cache;

[0044] Step S3: If the power consumption information data corresponding to the retrieval request is not found in the cache, according to the retrieval request, search for the power consumption information data corresponding to the retrieval request in the massive power consumption information database.

Abstract

The invention discloses an electricity information data retrieving method and device, and relates to the field of power. The electricity information data retrieving method and device are used for improving the speed of electricity information data retrieving. The electricity information data retrieving method comprises the steps of using multiple electricity information data to construct an electricity information database with large capacity; conducting statistics on accumulated retrieving times of the electricity information data, and utilizing the electricity information data of which accumulated retrieving times meet an accumulated retrieving threshold value to construct a cache; searching the cache for the electricity information data which corresponds to the retrieving request according to a retrieving request; searching the electricity information database with large capacity for the electricity information data which corresponds to the retrieving request according to the retrieving request if the electricity information data which corresponds to the retrieving request is not searched in the cache. The electricity information data retrieving device comprises the electricity information data retrieving method. The electricity information data retrieving method is used for improving the speed of electricity information data retrieving.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method and device for retrieving electricity information data. Background technique [0002] As an important part of the electricity consumption information collection system, smart meters will generate massive amounts of electricity consumption information data over time. In order to realize power consumption monitoring, and finally achieve the purpose of load forecasting and saving power consumption costs, it is necessary to quickly query and research and analyze power consumption information to help quickly detect faults such as power outages, and to coordinate household and business power distribution during peak power consumption, etc. Power management. [0003] The statistical results show that 71% of the access requests focus on 15%-28% of the data for accessing massive power consumption information data. However, the existing big data retrieval methods do not take into ac...
