Technical Field

[0001] The present application relates to the technical field of weak electricity, and in particular to a weak electricity distribution structure for floors of a building. Background Art

[0002] The weak current distribution structure of a floor refers to the layout of lines and equipment used to transmit and distribute weak current signals in a building. Weak current systems mainly include communication, monitoring, fire alarm, building automation, cable TV, access control and other systems.

[0003] With the development of science and technology, the demand for weak current systems in modern buildings is increasing. Traditional weak current wiring methods often adopt centralized management, that is, the signals of each subsystem are transmitted to each floor through the trunk cable, and then distributed to the terminal equipment by the branch lines within the floor. Although this traditional method meets the needs to a certain extent, it exposes many problems in actual application. First, centralized management leads to excessive cable length and dense and chaotic cables, which increases costs and failure rates; secondly, it is difficult to maintain multiple cables. Once a failure occurs, it takes a long time to troubleshoot and repair. Summary of the invention
