Metro Wireless Dispath Communication System Design And Implementation

Wireless communication system for railway traffic system is an important method for efficient communication between internal fixed personnel. In this thesis, the digital trunking communication system for subway is studied. The main results include:The requirement analysis for subway wireless communication system is conducted. Moreover, a whole design scheme has been proposed by analyzing other aspects f this system, which include technological regime, components and functional characteristics digital trunking communication system. Also, current situation for Batong line in Beijing is considered.By analyzing the specific requirements of the subway wireless dispatching subsystem, a designing scheme has been proposed. In the scheme, the coverage and network design of this system is given and the coverage efficiency is studied. Additionally, function design and structure design are also accomplished.Through the function analysis of the wireless dispatching system in Batong line, tfie designs for dispatching station and vehicle platform are given. Both the software and Hardware of vehicle platform have been designed and deployed, also protocols for wireless communication between dispatching station and vehicle platform are achieved.The test for wireless dispatching communication system is accomplished and the results show that this system meets the requirements.
