The invention discloses a digital twin urban traffic light control system based on Internet of Things, which relates to the technical field of intelligent control, comprises an acquisition module, an analysis module and a control module, and is used for calculating a congestion degree change rate, obtaining a concentrated time period, calculating a weight of historical natural data, constructing an interference function, and calculating an interference duration and a new concentrated time period. And establishing a traffic model, comparing the new congestion degree change rate with a congestion degree change quantity threshold value, executing a first operation, and establishing a first mapping relationship. Through real-time monitoring and analysis of traffic flow and congestion degree change conditions, consideration of influence of natural environment factors, optimization of passing time distribution of traffic flow, dynamic adjustment of a control strategy of traffic signal lamps, and analysis of historical traffic data and natural data, future traffic conditions can be predicted, and the traffic control strategy is optimized. Corresponding traffic signal adjustment and route planning are made in advance, and remote monitoring and centralized management of the traffic light control system can be achieved through application of the Internet of Things technology.

    本发明公开了基于物联网的数字孪生城市交通灯控制系统,涉及智能控制的技术领域,包括采集模块、分析模块和控制模块,计算拥挤度变化率,得到集中时间段,计算历史自然数据的权重,构造干扰函数,计算干扰时长和新的集中时间段,建立交通模型,将新的拥挤度变化率与拥挤度变化量阈值进行比较,执行第一操作,并建立第一映射关系。本发明通过实时监测和分析交通流量、拥挤度变化情况,以及考虑自然环境因素的影响,优化交通流的通行时间分配,动态调整交通信号灯的控制策略,通过历史交通数据和自然数据的分析,能够预测未来的交通情况,提前做好相应的交通信号调整和路线规划,物联网技术的应用使得交通灯控制系统能够实现远程监控和集中管理。
