Wireless Train Dispatching System Design And Implementation Based On MPT-1327 Trunking Communication Protocol

Train dispatching system is a very important part of the railway transportation. To match some new requirements, a trunking wireless train dispatching system is designed.At the beginning of the thesis, there is a general introduction of the trunking communication, MPT-1327 protocol and Radio Operation System.Then there is the overall structure of the System, and introduction of the components and network construction.For a wireless train dispatching system, the transmission and receiving of the command is the vital part of the system. The main part of the thesis describes the design and implementation of the command transmission and receiving management component. Requirements are clarified and mapped to functional points. Interfaces and relationships are also declared. According to the design, the component is divided into 6 subsystems. For each subsystem, it describes interfaces and variables. For each function, it gives the functional description and the parameters. There is also some description for the construction of the important functions. Finally, the unit test ensures the stability of the command transmission and receiving management component.The new system has the capability of centre control, can make train dispatching more normal and effective. It's a suitable design to match the new requirements.
