(Graduation work, everyone can see, only the teaching building and library. . . For the first time, everyone gave suggestions. The general goal of building construction is to build a multi-purpose office automation system with the support of high-performance integrated wiring system, which can adapt to the increasingly developing modern and intelligent buildings. So as to realize the complete set of on-demand control of the building's electrical, fire prevention, security, monitoring, computer communication, etc., to achieve resource sharing and external information exchange. The design scope includes the office area, management area and other public areas of the entire building. It is required to adopt an advanced, mature, reliable and practical structured wiring system, and the program-controlled switch system and computer network system in the building shall be wired and managed in a unified manner, so that the entire building can be managed in a unified manner. The building becomes a flexible and easy-to-expand intelligent building system that can meet the high-speed information transmission in the future. .....)
