Design and research scheme of public network communication system during metro construction based on wireless indoor distribution technology
In the process of metro construction,it is difficult for operators and managers to realize real-time communication with the outside world due to the lack of public network signal coverage.To tackle this issue,this article proposes a public network communication system design scheme based on wireless indoor division technology during metro construction.To verify the feasibility and effectiveness of the scheme,the research team set up a test platform at Luojiaji station of Nanchang metro line 2 east extension section for real-time testing,at the same time,the standard attenuation factor model is used to simulate and calculate through MATLAB software,finally,the simulation theoretical value,test value and specification requirements are compared.The research results show that the system can provide stable wireless communication signals in the process of metro construction,and effectively solve the issues of discontinuous signal coverage and blocked communication in underground and above-ground wireless networks.To consider the balance between cost investment and long-term application value,the research team also conducted an in-depth analysis of the project economics,and the analysis results show that the equipment used in this project has a high rate of recycle and reuse in the construction of the subsequent extension line communication system,which could not only reduce the long-term cost,and also reflect good generalizability and sustainability,and may provide reference and inspiration for similar projects.
