Road traffic double-core signal control machine and control system with same

Abstract

The invention discloses a road traffic dual-core signal control machine and a control system with the same. The dual-core signal control machine comprises a main body cabinet, a first chip control unit and a second chip control unit, the first chip control unit is used for controlling the signal phase state of each traffic signal lamp group according to a pre-stored phase timing scheme; the second chip control unit is used for judging whether adjustment factors exist or not according to the real-time traffic data collected by the intersection detection equipment, and dynamically adjusting phase timing and an execution sequence in the current phase timing scheme executed by the first chip control unit under the condition that the adjustment factors exist, so as to generate a new phase timing scheme; and the first chip control unit controls the signal phase state of each traffic signal lamp group according to the new phase timing scheme. According to the invention, a dual-core design is adopted, the lighting of traffic lights is stably controlled, optimal timing and edge calculation are carried out on traffic signals, and the state of the traffic signals is dynamically adjusted in real time.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, and more specifically relates to a road traffic dual-core signal control machine and a control system having the same. Background technique [0002] With the rapid development of my country's economy and society, urbanization and the construction of metropolitan areas are accelerating, which greatly promotes the development of urban transportation technology, but also poses great challenges to urban transportation. According to statistics, the losses caused by traffic congestion in big cities in my country are hundreds of billions of dollars every year, and the economic losses caused account for about 5% of their GDP; and whether urban traffic congestion is restricted by each intersection in the road network, according to relevant According to statistics, about 1 / 3 of the travel time of vehicles in the city is spent at road intersections. Therefore, under the constraints of lim...

Problems solved by technology

[0003] At present, traffic signal controllers are generally used to implement cyclic control on the corresponding phases according to preset programs. Few signal controllers can combine real-time intelligent calculation and stability control according to specific traffic conditions to optimize traffic. control
