technical field

The invention relates to the field of traffic control, in particular to an intelligent traffic control system with an LED light bar and a position sensor.

Background technique

The traffic flow of the road will be significantly different and will change significantly in the opposite lane, especially in areas with obvious tidal traffic flow.

The method that utilizes movable divider bar has occurred in some traffic control modes now. When the traffic flow in the forward lane is large, the optional lane is classified as the forward lane, and when the traffic flow in the reverse lane is large, the optional lane is classified as the reverse lane. However, due to the complexity of the movement of the partition and the inability to achieve intelligent control, it is not widely used in some areas.

After that, the driving trolley is lifted off the road surface and rotated so that its longitudinal direction is along the lane dividing line between the second lane and the third lane.

Through the above scheme, since the driving trolley has a certain longitudinal length, it will have an impact on road driving when it is not in use at ordinary times, and the present invention uses a rotating mechanism to rotate it until the driving direction is consistent, thereby avoiding this problem; at the same time, using the driving The longitudinal length of the trolley can fully guarantee the stability of the partition when it is being moved. Moreover, by using the lifting drive mechanism, it can not only put down the hoisted driving trolley, but also continue to run to lift the column off the road to move it; similarly, by using the sufficient weight of the driving trolley itself, it can be separated in the next partition. Reinsert it into the column hole at the line; and use the positioning roller under the driving trolley to drive the driving trolley to a suitable position. The positioning roller has the freedom to move up and down, which can fully meet the roughness of the road and positioning during driving. The unevenness of the groove itself and other requirements.
