The comprehensive wiring training room of network engineering is the only development of computer network engineering, and the network engineering and related majors of intelligent buildings are emerging rapidly with the development of Internet and intelligent buildings. With the rise of intelligent buildings in recent 10 years, the network engineering of intelligent buildings has developed to almost all buildings. Therefore, in 2000, the National Bureau of Standards formulated two recommended specifications for integrated wiring: Code for Engineering Design of Integrated Wiring Systems (GBT 5031KLOC-0/-2000) and GBT503 12-2000.
