Embodiment 1

[0043] The composition of the actual traffic signal control system is as follows: figure 1 shown. exist figure 1 Among them, the signal machine 11 drives the signal light 12 to control the traffic at the intersection, and at the same time, the signal machine 11 collects the vehicle arrival information of the detector 13 in real time. When the intersection signal control method adopts single-point induction or adaptive control, the signal machine 11 calculates the signal timing information according to its own control algorithm; in the coordinated control of the main line or area, the signal machines at each intersection send the vehicle detection information to the host computer 14. A signal control optimization algorithm is installed in the host computer 14, and the host computer 14 outputs signal timing information according to the control algorithm and sends it to the signal machine 11. The signal machine 11 in the traffic signal control system takes the vehicle arrival...

Abstract

The invention relates to a hardware in-loop simulation test system for a traffic signal control system, and relates to the technical field of traffic signal control and traffic simulation, for overcoming the defects that a practical signal control system cannot support prior evaluation and traffic simulation software can not simulate a timing scheme of the signal control system in real time. The test system consists of the traffic signal control system, signal conversion equipment and a traffic simulation module, wherein one-to-one or one-to-many data transmission between the signal conversion equipment and a signal machine and between the traffic simulation module and the signal conversion equipment can be realized by wire/wireless connection. The signal conversion equipment can be interface equipment which independently runs, or an input/output card on a main board of a computer, or a universal interface assembled on the signal machine and the computer. The data transmission takes the signal conversion equipment as a bridge, vehicle detecting information is transmitted to the signal machine by the traffic simulation module, and signal timing information is transmitted to the traffic simulation module by a traffic signal controller.

Description

technical field [0001] The invention belongs to the technical field of traffic signal control and traffic simulation. More specifically, the invention relates to a hardware-in-the-loop simulation test system for a traffic signal control system, which is applied to the scientific pre-evaluation of the control effect of the signal control system. As an experimental teaching tool for students majoring in traffic engineering. Background technique [0002] The traffic signal control system is an important subsystem of the intelligent traffic management system. Its main function is to automatically coordinate and control the timing scheme of the signal control machines at each intersection in the entire control area, to balance the traffic flow in the road network, and to reduce the number of stops and the delay time. and environmental pollution to a minimum, and give full play to the traffic benefits of the road system. The traffic signal control system is generally composed of ...
