DRTD系统固定电台数据管理控制模块的设计实现OA

The Digital Radio Communication System for Train Dispatching(DRTD)based on digital communication technology will serve as an alternative solution of the 450 MHz train dispatching system.As the functional subject of the station side in the DRTD system architecture,the fixed station is responsible for intercommunication with the center side,adjacent stations,and other wired and wireless system components that require data and voice intercommunication.This paper conducts reasonable module distribution and function design for the data management and control module of fixed radio according to the type of each sub-function and the relation between each other,which is divided into multiple sub-modules,such as database processing module,data receiving and sending module and information management and control module.The multi-threaded architecture is used for the development of the background service program of the module,to ensure the processing efficiency of the module functions,which effectively supports the function realization and system stability of the whole DRTD system.The module software has been applied in the field test and runs stably.
