Wang Jia, Shufeng Liu, Chen Zhixin, Xiaohui Wang · 2010
A network construction model of underground transportation hub safety monitoring center is proposed in this paper according to the disadvantages of present management mode in underground transportation hub. Taking transfer station from two different lines as an example, network analysis of the information transmission for BAS (Building Automatic System) and FAS (Fire Alarm System) which affect subway safety directly in the whole safety monitoring system is made and basic requirements for network deployment are obtained. Finally, data transmission and command control among PLC, hub station, HCC (Hub Control Center), and TCC (Traffic Control Center) are realized through the software platform based on Cybercontrol.
