(The integrated wiring system is the physical platform used by the network. As the infrastructure for carrying the network use and information technology, it plays a key role in the intellectualization of buildings. Intelligent wiring provides a more convenient, user-friendly and intelligent solution for the management of the integrated wiring system. The core of the system is the management of the physical layer, including the monitoring of the connection/disconnection status of the entire physical link. In order to achieve the real-time monitoring of the physical layer, the design and use of the hardware and the software supported by the intelligent wiring system are different from those of the ordinary integrated wiring system. Based on different office principles of software and hardware, the design of intelligent wiring can be divided into two modes: single distribution frame and double distribution frame in the intelligent distribution frame part. Here we start from the office principles of the two modes, and compare the advantages and disadvantages of the two modes in the field of engineering use.)
