| The crossing is the junction of railway and road traffic, its safety not only relates to the safety of railway traffic, but also relates to the safety of vehicles and pedestrian. In this dissertation, taking the Daqing oil field crossing as the application object, the key technology involved in crossing comprehensive supervision control system (CCSCS) is analyzed and the software of CCSCS was developed. The main research points are as follows:Firstly, by analyzing the working process of crossing system, the functional requirements of CCSCS were analyzed.Secondly, the functional decomposition scheme of CCSCS was proposed, and then interface relationship among security host, control center and outdoor equipments was defined. Furthermore, the structure of CCSCS was designed.Thirdly, the software, to achieve logical operation, gathering & driven, communication and other functions, was developed. And the assistant software, to achieve man-machine interface and information management, was developed.Finally, the integrated debugging of CCSCS was carried, and the results show that the CCSCS software proposed in thesis meet the requirements of the working processes of crossing. |
