基于组态软件的城市交通运行演示系统

Urban Traffic Operation Demonstration System Based on the Configuration Software

结合交通类本科专业学习的重点和难点要求,开发了基于KING SCADA组态软件的城市交通运行监控实验演示系统。该系统以单点信号交叉口设计、信号相位动态演示、感应控制、交通运行状态报警控制等模块的设计为分目标,以路网交通运行状况监控与协调控制的综合实验环境设计为总目标,从精灵图设计开始,设计了各种信号灯模型、交叉口渠化模型、相位演示模型和典型相位信号灯数据模型。利用KING SCADA软件数据模型实例化的规模性,实现了复杂路网多交叉口条件下的简化设计。利用数据库模型实现了路网协调运行监控系统的动态演示,并开发了交通运行报警查询,饱和度计算,报表查询,趋势曲线等附加功能,给学生提供一个直观、生动、系统、安全和开放的实践教学环境。

Combined with the key and difficulty of traffic undergraduate learning requirements, a city traffic monitoring demonstration system based on the KING SCADA configuration software was developed. The partial objectives of the system design are single intersection design, signal phase design of dynamic demonstration, induction control, traffic state alarm control model, and the total target is the comprehensive experimental environment of traffic monitoring and coordination control design. From the designing of the elves, various signal model, intersection channelization model, phase demonstration model and typical phase signal data model were designed, too. Using the scale characteristic of the data model instantiation of the KING SCADA software, simplify design Can be realized under the condition of the complexity road network. The dynamic demonstration of the network coordinated operation monitoring system was realized by the data base model, the traffic alarm query, saturation calculation, report query, trend curve and other additional features were developed, which can provide an intuitive, vivid, system, secure and opening practice teaching environment for students.
