And the architectural environment using the experience of people as final goal optimizes.Wherein, acquisition, processing, analysis and the intelligence of diversification data
Judgement is to realize the precondition of functional facilities manipulation and architectural environment state optimization.
Data are the bases of building intellectualization.For a long time and high-frequency acquire and preserve what is perceived from intelligent building
Data, acquire and preserve with particularly becoming more meticulous intelligent building ontology and its functional facilities in all directions, the data of polymorphic type, be real
Condition necessary to what incumbent subsequent intellectual analysis and regulation and control.At present, although the requirement of the building standards such as LEED or the long-term guarantor of encouragement

Outer a plurality of types of environmental parameters are acquired, including illumination parameter, temperature parameter, humidity parameter, noise parameter, smog sense
Should, air particle parameter etc., this just needs to install a large amount of various kinds of sensors；Meanwhile a large amount of work(is also installed inside building
Energy facility, such as headlamp, fire-fighting water spout, air-conditioner air outlet, air purifier, automatic curtain, etc..We are by above-mentioned biography
Sensor and functional facilities are referred to as operating facilities.Operating facilities quantity is more, type is more, spatial position dispersion.For example, in order to take precautions against
Fire and the smoke sensor device for being used to monitor smog, as soon as each room is at least, then entire building has hundreds of distributions
In each room；Equally, for the illumination in accurate measurements building room, each room the inside needs to install several illumination sensings
Just there is hundreds of optical sensor in device, this building, are dispersed in each place of building.It is as it can be seen that large and medium-sized at one
In building, the data sampling point being made of each operating facilities has thousands of, and the data volume of output is also very big.
Data caused by the operating facilities of these substantial amounts and spatial dispersion are analyzed and management is one non-
Often difficult and time consuming work.In traditional technology, from the background to the status data of each operating facilities obtained by Internet of Things,
All it is to be summarized, and be shown to administrative staff in the form of list records.But it is recorded and shown in a manner of list all
The state of operating facilities is not very intuitive, is also unfavorable for the effective analysis of status data expansion to operating facilities.Currently based on table
Single analysis method is mainly superthreshold alarm and the inquiry according to number or implementor name, for example, if encountering exception causes certain
The status data numerical value of a operating facilities has exceeded the normal range (NR) of permission, then shows pop-up, and giving alarm to administrative staff carries
Show.This analysis means are excessively single, it is impossible to it is true reflect in intelligent building the virtual condition of all kinds of operating facilities and its
Zonal development and change situation.Moreover, because various and standard disunity of source and type, intelligent building ought at present
In the operating facilities such as sensor, functional facilities lack unified naming ＆ numbering specification, with general querying method or
List methods of exhibiting is all difficult that desirable data point is searched in thousands of sampled data points, this greatly increases
People has been added to use the difficulty of these data in management and analysis phase.
