Preferably, the measurement coverage of described laser range finder is 1km, and the angle of divergence is less than 1.2mrad.
Preferably, the height being actually needed described in is the height of overhead 60cm.
Preferably, the frequency of described laser range finder is more than 10Hz.
Preferably, described single-chip microcomputer is communicated by serial ports.
Preferably, described turntable is controlled by serial communication.
Preferably, the load-carrying of described turntable is more than the weight of video camera.
Preferably, described turntable and described video camera are integration apparatus.
Preferably, described video camera is Zoom camera.
The technical solution of the utility model has the advantages that
The one that this utility model provides, based on laser positioning and high definition Along Railway safety monitoring system, utilizes laser
Ranging technology and single-chip microcomputer control technology, carry out monitoring in real time in 24 hours to railway, to avoid pedestrian or domestic animal to be strayed into road junction, from
And avoid potential safety hazard, lower security incident incidence rate；The image of the pedestrian being strayed into or entering railway road intentionally is obtained simultaneously
Take, it is warned afterwards；Simple to operate, reliability is high；Preferably auxiliary care provider carries out railway monitoring, improves work
Efficiency.
Accompanying drawing explanation
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Fig. 1 is that a kind of system structure based on laser positioning with high definition Along Railway safety monitoring system of this utility model is shown
It is intended to；

System figure.
Detailed description of the invention
In order to have a clear understanding of the technical solution of the utility model, its detailed structure be will be set forth in the description that follows.Aobvious
So, the concrete also deficiency of implementing of this utility model embodiment is limited to the specific details that those skilled in the art is familiar with.This reality
It is described in detail as follows with novel preferred embodiment, in addition to these embodiments described in detail, it is also possible to there is other embodiment party
Formula.
With embodiment, this utility model is described in further details below in conjunction with the accompanying drawings.
This utility model one is based on laser positioning and high definition Along Railway safety monitoring system, in conjunction with Fig. 1 and Fig. 2, Fig. 1
It it is a kind of system structure schematic diagram based on laser positioning Yu high definition Along Railway safety monitoring system of this utility model；Fig. 2 is
A kind of overall railway system figure based on laser positioning with high definition Along Railway safety monitoring system of this utility model.
One shown in figure is based on laser positioning and high definition Along Railway safety monitoring system, including be sequentially connected electrically
Laser range finder, control unit, video camera and rotation platform, described laser range finder height according to actual needs is pacified
Dress, described control unit includes single-chip microcomputer and audio output device, described position for video camera on described rotation platform, described laser
Diastimeter constantly sends laser pulse signal and obtains range information the range information transmission the most described control list that will reflect back into
Unit；Described single-chip microcomputer is electrically connected with described laser range finder, the reality that described single-chip microcomputer obtains according to described laser range finder
Range information determines whether that pedestrian is in orbit: if described single-chip microcomputer judges there is people on rail, described single-chip microcomputer sends control
System instruction performs alarm prompt to alarm device, alarm device, and the most described single-chip microcomputer obtains pedestrian through calculating and relatively images
The distance of machine and angle, described single-chip microcomputer sends control instruction to described rotation platform, described rotation platform according to result of calculation
Turning an angle and make pedestrian in camera field of view, and the focal length regulating photographic head makes photographic head clearly obtain person image,
Described single-chip microcomputer has serial communication function, and described turntable is controlled by serial communication, and the load-carrying of described turntable is big
Being integration apparatus in the weight of video camera, described turntable and described video camera, described video camera has zoom function.
