城市交通控制系统信号控制单元集成化研究

Research of Integration of Traffic Signal Controller in Urban Traffic Control System

在分析当前城市交通信号控制系统发展趋势的基础上,针对我国城市交通实际应用中存在的各类信号控制单元自成体系难以统一的问题,提出了一个实用的信号控制单元集成的解决方案,首先介绍集成化城市交通控制系统,然后介绍信号控制单元集成化方案的功能框架和技术实施方法,从而实现了一个控制系统软件可以兼容多种不同型号信号机的目标,并且在实际系统开发中获得了应用。

Based on the analysis of development trend of urban traffic control system, intelligent and integrated, as to the problem that the integration of various traffic signal controllers in various traffic control systems, the paper presents a practical solution about the integration of urban traffic signal controllers, with integrated urban traffic control system, discussing the system architecture and two main components： Main Control Module and Communication Protocol Conversion Module, as well as the function architecture and the technology implementaion approach of the integration of urban traffic signal controllers, including the development environment, program language, database system and so on, to achieve the compatibility of urban traffic control system to several kinds of controllers of various manufactures. The Communication Protocol Conversion Module, was developed and applied in actual system.
