Signal equipment room construction involves a significant amount of cable laying and welding,and often faces such challenges as tight timeline,labor shortage,limited resources and poor construction environment in the case of retrofitting projects of existing lines,and projects in overseas markets and harsh environments.This paper analyzes the constraining factors in signal equipment room construction,and provides a visual comparison between the traditional construction method and the factory fabrication method to introduce the key technical aspects of the factory prefabrication technology in signal equipment room construction.The factory prefabrication technology for signal equipment room construction adjusts the equipment layout and wiring nodes,modifies the wiring method of cabinet equipment without changing the existing interlocking relationships and control circuits.Thus,it allows standardized production at the factory with cabinet as the basic unit,as well as inter-cabinet construction at the construction site featuring bundling and plug-and-play.The proposed factory fabrication method,which features modularization,standardization,plug-and-play and bundling,can greatly simplifies the on-site wiring and debugging work,and effectively reduce the on-site construction time,to ensure construction safety at low construction costs.
