Intelligent and integrated traffic signal controller

Abstract

The invention discloses an intelligent and integrated traffic signal controller, which relates to the technical field of automatic controllers. The intelligent and integrated traffic signal controller consists of a signal input module, a data processing and storage module, a master control optimization module, a signal output module and an external interface module, wherein the signal input module is connected with the data processing and storage module and the master control optimization module; the data processing and storage module is connected with the master control optimization module; the data processing and storage module and the master control optimization module are connected with the signal output module respectively; and the master control optimization module is connected withthe external interface module. The intelligent and integrated traffic signal controller provided by the invention realizes the integrated control and information sharing of different kinds of trafficequipment comprising traffic signal control equipment, a traffic guidance screen, an electronic police and a video monitor at intersections, and is endowed with relatively higher real-time control and coordination capacity so as to meet the requirements of development of an intelligent traffic system.

Description

technical field [0001] The invention relates to the technical field of automatic controllers, in particular to the technical field of traffic control. technical background [0002] At present, the research and development of traffic signal controllers at home and abroad are only limited to controlling traffic lights at intersections. And the generation of the traffic light signal scheme is generated by the timing or multi-period control scheme stored in the traffic signal controller. Although in order to adapt to the development of traffic, some manufacturers have added control algorithms and control methods in the traffic signal controller, but it is still limited. On adjusting the traffic light signal for traffic flow; or the traffic signal controller transmits the collected traffic information of the intersection to the database server of the traffic command center, and then the signal timing optimization server of the traffic command center optimizes and generates the tr...
