Description
Technical field
The present invention relates to detection performance technology fields, specifically, more particularly to a kind of laboratory bridge prison based on BIM
Survey teaching demonstration system.
Background technique
Currently, visualization technique is to convert abstract data to using image procossing and graphics to be readily appreciated by
The technology of image or figure.Visual concept starts from visualization in scientific computing, and staff not only needs with figure or image
This visual in image mode goes description data, while being also required to understand the variation tendency of data to which the tendency to data carries out
Prediction, as the intersection between different subjects is more and more and the fast development of computer technology, visualization have been not only
Refer to visualization in scientific computing, but also the visualization including engineering field data.From 20th century, as the high speed of science and technology is sent out
Exhibition, various new materials, new process are continued to bring out in civil engineering industry, so that engineering structure is constantly to complication, enlargement hair
Exhibition, while but also the health monitoring systems of structure inevitably develop to complication, enlargement.Monitoring data are in health monitoring system
There is highly important status in system, be the scientific basis to structural stress state, degree of injury and life appraisal, after structure
Continuous maintenance and maintenance has highly important directive significance.But it with the enlargement of monitoring system, complicates, different type sensing
The magnanimity monitoring data of device acquisition can be transferred to the data acquisition subsystem in monitoring system in real time, cause staff to prison
Understanding, analysis and the processing of measurement information generate difficult.Therefore, the visualization for improving monitoring data is horizontal, reduces the understanding of data
Difficulty is necessary.
The full name in English of BIM is Building Information Modeling, and concept is by Charles earliest
In 70 generation of 19th century of Eastman et al., is put forward for the first time, and is the direct embodiment that informationization technology is applied to construction industry.By the hair of many years
There has also been more complete definition for the definition of exhibition BIM technology.BIM technology entered China in 2002, and domestic scholars also expand greatly
Quantifier elimination.Guangxi University of Science & Technology Deng Langni professor team has carried out about BIM technology in design phase, construction stage and O&M
The research of the Life cycle application in stage is difficult to realize fine-grained management to solve the problems, such as that CAD tradition arranges brick technology, utilizes
BIM kernel software Revit is platform, establishes race's file of brick, realizes the rapid and automation of simulation row's brick, reduce engineering at
This, by the integrated use to BIM kernel software, realizes that the visual simulating based on BIM model is answered to improve user experience
With.To improve the safety management problem in work progress, based on BIM model, using Pathfinder software realization to fire
The research of calamity simulation and safe early warning.Using secondary exploitation technology, the construction risk source safety management based on Revit is realized,
Reduce construction site safety accident generation and by BIM technology apply with to the research in engineering quality control.In the design phase,
Scholars utilize the function of Revit software collision detection more, carry out collision detection to the BIM model of full profession, discovery is set ahead of time
Blind area in meter reduces design alteration, improves the coordination between different majors.BIM the construction stage application more
It is mature, it can be achieved that construction site preferred arrangement, visualization construction tell somebody what one's real intentions are, progress simulation and quality examination etc., can be very good auxiliary
Help work progress, reduction is done over again, and is increased economic efficiency.In the O&M stage, many scholars, which combine RFID technique with BIM, to be answered
For by dynamic information integration into BIM model, being provided for building identification, indoor positioning, personnel escape etc. good in operation management
It is good to support.But since the problems such as operation management demand is indefinite and management is uncoordinated with technical level, leads to the O&M stage
BIM research is also in the primary stage, needs the intersection between multi-specialized.
To sum up, although BIM technology is more complete in the research of construction stage, in the research of design phase and O&M stage
There are also very long roads to need, and the problems in collection is how to carry out the interaction between different model informations and the friendship between subject
Fork research.
