- W2384130954 abstract "Research purposes: The subway is a public place that have a large passenger flow and dense population. It is more difficult to manage because of much emergency. In order to improve the security administration within the scope of the public security department of the subway,better service to the subway passengers,a wireless communication command attemper system of public security need to be set up to assure public security communication with subway employees and all departments of the public security bureau. This paper has introduced the development of wireless communication system at home and abroad,has carried on the analysis comparison of several common public security wireless communication system,and puts forward the recommended scheme of various circumstances,It can provide a reference for similar problems that meet in the subway design.Research conclusions:( 1) Public security wireless communication system scheme of urban rail transit should be consistent with the urban existing public security wireless communication system,and government affairs wireless communication system of city rail.( 2) Centralized way is recommended,which combining the scheme of wired and wireless introduction that wired scheme is given priority to and wireless solutions is standby.( 3) At the station platform layer and the underground tunnel,the leakage coaxial cable should be applied to for field coverage. At the station hall layer,the way of ceiling-mounted antenna should be adopted for coverage.( 4) Broadband multimedia cluster,such as TD-LTE with independent intellectual property,is the future development direction of public security wireless communication system in our country." @default.
