A split type traffic signal controlling machine system

Abstract

The invention discloses a split type traffic signal controller system, which is characterized in that the system includes a plurality of signal controllers arranged in different directions of a traffic intersection for performing traffic control in the corresponding directions. Each signal controller has a standard structure so as to be combined based on the traffic intersection scale, thereby improving expandability.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a split traffic signal controller system. Background technique [0002] In the prior art, the traffic signal control machine system mostly adopts a centralized control type traffic signal control machine at an intersection, and the traffic signal control machine controls the traffic in all directions of the intersection. Therefore, the traffic signal control machine is relatively large in size and takes up too many road resources. [0003] On the other hand, since the centralized traffic signal control machine needs to control the signal lights in all directions of the intersection, it is unavoidable to be connected with each signal light. In the prior art, most of them are connected by wire, which leads to a longer route between the traffic signal control machine and the signal lights in each direction, which damages the road more and costs more; and, because the traffic signal c...

AI Technical Summary

Problems solved by technology

In the prior art, most of them are connected by wire, which leads to a longer route between the traffic signal control machine and the signal lights in each direction, which damages the road more and costs more; and, because the traffic signal control machine By controlling the on and off of the alternating current to control the on and off of the signal lamp, the lead wire between the traffic signal controller and the signal lamp is long, resulting in a large electromagnetic radiation pollution

[0004] In addition, the existing traffic signal controllers cannot adjust the brightness of the signal lights in real time according to the brightness of the ambient light. At night, the brightness of signal lights is rather dazzling, causing discomfort to pedestrians and drivers, and wasting electric energy

[0005] On the other hand, because a crossing in the prior art adopts a centralized control type traffic signal control machine, this traffic signal control machine can only be applicable to the situation that the crossing scale is less than or equal to this crossing after leaving the factory, and for the crossing scale greater than this crossing In other cases, it cannot be used, and the scalability is poor
