- 摘要：In recent years, the development of digital management of buildings and the rise of BIM technology have greatly integrated computer automation technology into the engineering construction industry. However, there are few studies on the application of the combination of the two in the construction operation and management. This paper takes the teaching building of the School of Civil Engineering of a university as an example, establishes a platform of building digital management based on BIM technology with the help of Revit2016 software and Da Xiang Yun platform and web page production. Through this platform, users can browse 3D modeling, understand the general situation of the college and the architectural structure; Teachers and students can combine BIM model to teach and learn courses, such as project evaluation, building architecture and so on; Combined with the room distribution plan, users can also query the empty classrooms of the teaching building and monitor them. The platform of building digital management constructed in this paper achieves the visual operation of teaching and the intelligent management of buildings by integrating BIM technology with computer web design technology.关键词：BIM technology;building management;digital platform

发布时间：2022-03-17 - 摘要：In the automatic fire alarm and linkage system, a dedicated fire telephone system is an integral part. In a large building, fire telephone extensions are installed in the power distribution room, the fire fan control room, the fire pump room and the gas fire extinguishing operation devices, so that one can communicate directly with the fire control room by picking up the telephone; At the same time, fire telephone jacks are also installed next to the manual fire alarm buttons evenly distributed in the building, so that one can talk to the fire control room by inserting a portable telephone extension in case of emergency. According to the communication principle of fire telephone host and terminal equipment, fire telephone systems can be divided into two types, bus and multi-line, and their different modes of operation have an impact on the length limits of fire telephone lines. This paper examines the limiting factors for the length of telephone lines in dedicated fire telephone systems and gives the limit lengths (maximum lengths) of various commonly used telephone lines for application in fire telephone systems through calculation. According to the engineering calculation table given by the author, the main factors affecting the call quality of the fire-fighting special telephone system are the interline insulation resistance and interline capacitance.关键词：fire alarm;fire telephone;telephone line;length
