Report.Prevention driver all kinds of shock accidents because of negligence or caused by the reasons such as not knowing about to this height of car, effectively reduce
Personnel's property loss that vehicle brings the damage of the facilities such as bridge, culvert and accident.
2, the accident after the Overheight Vehicles early warning video of the system acquisition can occur for such collision, which is traced, provides evidence；
3, the system principle is simple, install convenient, a variety of power supply modes, and environmental suitability is strong, also can be used as the limit of other field
High ancillary equipment has prodigious market application value.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and embodiments：
Fig. 1 is the structure principle chart of the limit for height anti-collision early warning system based on laser sensor；
Fig. 2 is the hardware block diagram of the limit for height anti-collision early warning system based on laser sensor；
Fig. 3 is the working-flow figure of the limit for height anti-collision early warning system based on laser sensor.
Specific implementation mode
In order to make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment and join
According to attached drawing, the present invention is described in more detail.It should be understood that these descriptions are merely illustrative, and it is not intended to limit this hair
Bright range.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid this is unnecessarily obscured
The concept of invention.
Embodiment
As shown in Figure 1, 2, a kind of limit for height anti-collision early warning system based on laser sensor, include connect with controller by
Laser emission and reception device, video acquisition device, communication device and warning device, Laser emission includes infrared with reception device
Laser and laser sensor（Reception device）, point shaped laser spot can be formed in body surface using the laser of infrared laser transmitting
And received by sensor to realize the principle of object detection, it is installed on the limit for height point position of bridge or culvert, example in the device
In limit for height bumper frame.Infrared laser emission device is installed on driving device, and the driving device drives Infrared laser emission device water
Flat uniform rotation, after unlatching, Laser emission at the uniform velocity rotates carry out level with sensing device, and infrared laser continues to emit outward
Infrared laser, emitting area are 180 ° of front horizontal zone, transmitting range >=100m.When laser sensor is not received by reflection
When infrared laser back, show in front region without barrier, i.e. Overheight Vehicles；When sensor receive it is reflected
When infrared laser, show that there is Overheight Vehicles appearance in front, subtitle of alarming by control warning device progress sound-light alarm and by LED
Driver is prompted, meanwhile, video acquisition device is by the video information transmission of automatic recording Overheight Vehicles to network management
From the background.
Laser emission and sensing device：Including infrared laser and laser sensor, infrared laser for emitting outward
Infrared laser line, laser sensor reflects infrared light for receiving by barrier, and is filled with video acquisition device, alarm
It sets and carries out I/O communications；
