Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] A method for compressing massive energy consumption information in an intelligent building, the steps are as follows:

[0020] 1) Design the on-line real-time monitoring of intelligent building energy consumption information. Each record is a triplet: (tagid, time, data), which respectively represent the point number, data collection time, current data status and collected data ;

[0021] 2) When the temporal attribute value of an object in the system changes, the new value is not directly stored in the data file, the system stores the value in the first-level buffer, and then directly returns to the next task, and these data are provided by The background data storage thread is responsible for storing files;

[0022] 3) Set up a secondary cache. The L1 cache is a data queue shared by the data management thread and the data storage th...

Abstract

The invention relates to a compression method of the mass energy consumption information in an intelligent building, which comprises the following steps that: (1) the data on the monitoring end in the building are collected, and each record of the recording points of the collected data is one triple group (the tagid, the time and the data); (2) when the tense attribute value of some recording point is changed, the corresponding new data are stored into the first stage of buffering, then the next task is directly carried out, and the new data are stored into files through a background data storage thread; (3) the second stage of buffering is established; (4) a historical data compression region is arranged, and the data in a buffering region are transferred to a disk file after being compressed in the compression region; (5) the data files are organized by adopting the form of a file queue, and the next file in the file queue is started after the file is fully stored; and (6) the compressed data are stored into a storer and supplied to the required client to call after the compression is finished.

Description

technical field [0001] The invention relates to the technical field of building energy consumption monitoring, in particular to a method for compressing and decompressing massive energy consumption information in intelligent buildings technical background [0002] The online real-time monitoring of energy consumption information of intelligent buildings is to use electronic measurement and control technology to realize component monitoring of water, electricity, heating and other energy consumption in intelligent buildings, and to collect electric energy sub-item data; and to apply wireless sensor network technology to realize building monitoring. Regular collection and monitoring of indoor temperature and humidity, CO2, formaldehyde content and other environments; through the establishment of a data center, a provincial and municipal multi-level energy consumption supervision system is built. The energy consumption supervision system can analyze and count energy consumption...
