Example two

As shown in fig. 1 to 6, the present utility model further provides an anti-collision warning system for right turning at an intersection, which includes an anti-collision warning device 100 as described in any embodiment, where one side of one early warning display mechanism 2 of the anti-collision warning device 100, which has an information display screen 23, is disposed towards a right turning lane 101, and one side of the other early warning display mechanism 2 of the anti-collision warning device 100, which has an information display screen 23, is disposed towards a non-motor lane 102, so that a bidirectional detection and dual-screen information display manner is adopted to provide required early warning information for target groups of two lanes respectively.

Specifically, when the target detector 22 facing the right turning lane 101 detects that a large vehicle is on the right turning lane 101, that is, the right turning is performed, and the target detector 22 facing the non-motor lane 102 does not detect that the non-motor lane 102 has pedestrians or non-motor vehicle riders, the information display screen 23 facing the right turning lane 101 is triggered to display words such as "blind zone of attention, slow speed of running" and the like, and simultaneously, the information display screen 23 facing the non-motor lane 102 is triggered to display words such as "large vehicle passes, attention dodge" and the like;

when the target detector 22 facing the right turning lane 101 does not detect that a large vehicle is on the right turning lane 101, and the target detector 22 facing the non-motor lane 102 detects that a pedestrian or a non-motor vehicle driver is about to pass through an intersection, triggering the information display screen 23 facing the right turning lane 101 to display characters such as ' blind area is provided, caution is taken away ', and the like, and simultaneously triggering the information display screen 23 facing the non-motor lane 102 to display characters such as ' pass through the intersection, slow speed is reduced, and the like;

when the object detector 22 facing the right turning lane 101 detects that a large vehicle is on the right turning lane 101, the object detector 22 facing the non-motor lane 102 also detects that the non-motor lane 102 has pedestrians or non-motor vehicle riders about to pass through the intersection, the information display screen 23 facing the right turning lane 101 is triggered to display words such as 'dead zone has people, notice avoidance', and the like, and the information display screen 23 facing the non-motor lane 102 is triggered to display words such as 'large vehicle passes, notice avoidance', and the like.

In the display time period of the information display screen 23, the first voice horn 5 and the second voice horn 25 respectively broadcast the display content of the information display screen 23 on the same box 21 in a voice way, and meanwhile if the explosion flash lamp 24 is arranged, the explosion flash lamp 24 synchronously flashes to emit light for warning. Under the condition that the ambient light intensity is weak at night, in cloudy days and the like, the projector 8 automatically projects the display content of the information display screen 23 facing the non-motor vehicle lane 102 on the ground, and the projection position of the projector 8 is usually the non-motor vehicle lane 102, but when the zebra crossing area also needs to be warned, the display content can be projected on the zebra crossing area, so that the traffic safety of the large-sized vehicles at the intersection during the right turning is more comprehensively ensured.

In this embodiment, two warning display mechanisms 2 respectively provide warning information for the right turning lane 101 and the non-motor vehicle lane 102, so as to realize mutual warning between two lane target groups, thereby effectively avoiding the problem of incomplete information caused by warning only for a single target group, and effectively improving the traffic safety of different directions and different target groups at the intersection.

In some optional embodiments, the installation height of the early warning display mechanism 2 arranged towards the right turning lane 101 is greater than the installation height of the early warning display mechanism 2 arranged towards the non-motor vehicle lane 102, so that the problem of height difference between the target group of the right turning lane 101 and the target group of the non-motor vehicle lane 102 can be effectively adapted, the effectiveness and pertinence of early warning prompt are better, and the adjustment mode of the height difference is simpler and more convenient under the action of the second sleeve 7.

It should be noted that, fig. 6 only schematically illustrates the anti-collision pre-warning device 100 installed on the green belt between the right turning lane 101 and the non-motor vehicle lane 102, and the specific structure of the anti-collision pre-warning device 100 is shown in the first embodiment. In other alternative embodiments, the installation position of the collision avoidance early warning device 100 may be a position near the starting point of the right turning blind area, on the lane boundary between the right turning lane 101 and the non-vehicle lane 102, or the like, so long as the detection and early warning functions of the two lane target groups can be satisfied at the same time, which is not particularly limited in the present utility model.

The above embodiments are only for illustrating the technical idea of the present utility model, and the protection scope of the present utility model is not limited by the above embodiments, and any modification made on the basis of the technical scheme according to the technical idea of the present utility model falls within the protection scope of the present utility model; the technology not related to the utility model can be realized by the prior art.
