BIM BIMs（Building Information Modeling）It is the items with construction-engineering project
Based on relevant information data, it is established that three-dimensional BUILDINGS MODELS, by possessed by digital information analogue simulation building
Real information.It has information completeness, information relevance, consistency on messaging, visualization, harmony, simulation, optimization property and
Eight big feature of figure can be gone out.By the project participant such as construction unit, designing unit, unit in charge of construction, supervisor in identical platform
On, share same building information model.Beneficial to project visualization, become more meticulous construction.
BIM technology is frequently used to carry out the simulation before construction, is before Construction of Engineering Projects, is put down based on BIM
Platform, arrangement and method for construction is simulated, analyzed and optimized, is pinpointed the problems in advance, Prior Control is carried out, so as to instruct engineering project to apply
Work.This virtual analog can apply the arrangement simulation of the job site before bidding for project program simulation, engineering construction, vertical fortune
Coordination simulation and the simulation of complicated construction technique between defeated simulation, each professional subpackage etc..By shifting to an earlier date construction simulation,
Rework cost and management cost can be substantially reduced.
By developing rapidly for BIM technology in recent years, it has been found that closed according to the information completeness of BIM technology, information
Connection property, consistency on messaging, visualization, harmony, simulation, optimization property, BIM analogue techniques can first-class apply to building
In monitoring system, so as to improve the visualization of building monitoring system, information unified degree, optimize the standard of monitoring system
True property, the security of building is set to have obtained lifting largely.
Therefore it provides a kind of building monitoring system based on BIM technology is extremely important and urgent.
The content of the invention
It is an object of the invention to provide a kind of building monitoring system based on BIM, by establishing BIM BUILDINGS MODELSs
On the basis of building various aspects are precisely monitored, the visualization of building integral monitoring is realized, in order to coordinate associated monitoring
Equipment, when ensureing to monitor building dynamic comprehensively in place.
The present invention is achieved through the following technical solutions：A kind of building monitoring system based on BIM includes being used to gather front end
The detection unit of information, the front-end information for receiving collection are simultaneously computed being processed into the processing unit of corresponding parameter, are used for
Store the BIM data storage cells of BIM model information data, for corresponding parameter and BIM model informations to be integrated and sent out
Go out the main control server of control instruction, for receiving control instruction and carrying out the driving list of power amplifier processing offer equipment enabling signal
