Design of TETRA-based Dedicated Radio Dispatching System of Urban Rail Transit

摘要

The use of IP-based TETRA dedicated dispatching system design can enhance the system reliability, flexibility and scalability. In this paper, we propose the software architecture of dispatching server and dispatching client to achieve the necessary commanding and dispatching functions of the trunked system such as calling, monitoring and dynamic grouping. All of these measures have an important significance for the security of the safe operation of urban rail transit, the increase in system transportation capacity and the improvement of punctuality and the alleviation of dispatching work intensity.
