Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Embodiment 1
Referring to Fig. 1, the utility model provides a kind of guide waistband, including：Laser radar system 1, with laser radar
The controller 2 that system is connected, the prompting module 3 being connected with controller, and belt body 4.
Laser radar system 1 detects belt body 4 (i.e. user of service) ambient environmental conditions, the position of the testee of acquisition
Confidence ceases, and is uploaded to controller 2, and controller 2 receives and handles the positional information of testee, forms hint instructions, and will
Hint instructions pass to prompting module 3, and prompting module 3 reminds the ambient conditions around user of service.
As shown in Fig. 2 further, laser radar system 1 includes：First laser radar module 11 and second laser radar
Module 12, first laser radar system 11 are used to detect belt body surrounding environment along horizontal direction 360 degree of scannings, and second swashs
Optical radar module 12 is anterior located at belt body 4, for road conditions in front of short range scanning detection belt body.
As shown in Figures 2 and 3, in the present embodiment, belt body 4 is provided with front and rear two groups of first laser radar modules
11, two groups of first laser radar modules 11 work simultaneously, realize ring around horizontal direction 360 degree of scannings detection belt body jointly
The function in border, in other embodiments, first laser radar module 11 can be more than two, and particular number can be according to actual feelings
Depending on condition, the function of horizontal direction 360 degree of scannings detection belt body surrounding environment need to be only realized.
It is to be appreciated that first laser radar module 11 is used to detect belt body along horizontal direction 360 degree of scannings
Surrounding environment, above-mentioned horizontal direction is intended merely to description and conveniently not provided constraints, in real work, first laser thunder
Up to module detection plane 111 can with small range move up and down or and tilt, i.e., first laser radar module detection plane 111 has
The position of body can be fluctuated above and below the horizontal direction, and specific scope is depending on actual conditions.
In the present embodiment, first laser radar module 11 is obtained by the time difference for calculating modulation Laser emission and returning
Light path and then obtain the range information of testee and be uploaded to controller 2, can be achieved 360 degree of remote (in the range of 200 meters)
Environmental scanning detects, and precision is high, and scan frequency is fast, data real-time update, highly reliable, the details of detectable barrier,
Such as orientation, distance and velocity information etc., in other embodiments, first laser radar module 11 can also use other types
Laser radar obtain the range information of testee, such as the laser radar based on principle of triangulation, or its is any
Combination, same action effect can be achieved, therefore specific type is depending on actual conditions.
As shown in Figure 2 and Figure 4, second laser radar module detection plane 126 and first laser radar module detection plane
The 111 at a certain angle and transmitting of second laser radar module 12 light beams are oblique to shoot to ground.
As shown in figure 5, the emitting structural light of second laser radar module 12 detection front road conditions, second laser radar module are visited
Two dimensional surface of the plane 126 for covering certain angle is surveyed, higher angular resolution and scan frequency, second laser thunder can be achieved
The surrounding environment range information in structure light range of exposures is obtained using principle of triangulation up to module 12, accuracy of detection is high, can
It is strong by property, it can accurately detect closely interior (in the 6 meters) barrier in the front of belt body 4 and surface evenness information (barrier
Orientation, distance and shape and size information), can real-time detection road conditions.
As shown in Figure 2 and Figure 4, second laser radar module detection plane 126 and first laser radar module detection plane
Included angle A between 111 can be 0-90 degree, preferably 30-45 degree.
Included angle A between second laser radar module detection plane 126 and first laser radar module detection plane 111
For 0 degree when, second laser radar module detection plane 126 essentially coincides with first laser radar module detection plane 111, can be real
The existing front horizontal direction of belt body 4 is more accurately detected, bad to the road conditions Detection results in the front of belt body 4.
Included angle A between second laser radar module detection plane 126 and first laser radar module detection plane 111
For 90 degree when, second laser radar module detection plane 126 is vertical with first laser radar module detection plane 111, can realize

Individual region, although now detection range is farther out, sweep length is too small, and reliability is low, accident easily occurs；
When angle of coverage B is in the range of 60-110 degree, the scan area of second laser radar module detection plane 126 compared with
Ideal, when angle of coverage B be 60 degree when, the sweep length (2 meters or so) of second laser radar module detection plane 126 preferably,
The structure luminous energy that i.e. second laser radar module 12 is launched detects the region that width is 2 meters or so in front of belt body,
Farther out, Detection results are good for detection range.
When angle of coverage B is 110 degree, the sweep length (5 meters or so) of second laser radar module detection plane 126
Larger, i.e., the structure luminous energy that second laser radar module 12 is launched detects an area of 5 meters or so of width in front of belt body
Domain, detection range is moderate, and Detection results are preferable.
When angle of coverage B is 150 degree, the detection width of second laser radar module detection plane 126 is 12 meters of left sides
The structure luminous energy of the right side, i.e. second laser radar module 12 transmitting detects the area that width is 12 meters or so in front of belt body
Domain, sweep length is excessive, and detection range is excessively near, DeGrain.
It is to be appreciated that in the present embodiment, the detection width of above-mentioned second laser radar module detection plane 126 is
Refer to the length of intersecting lens when second laser radar detection plane 126 intersects with ground (ground is assumed to be horizontal plane)；Corresponding,
In the present embodiment, above-mentioned second laser radar module detection plane 126 is also based on second laser radar module detection plane
Intersecting lens when 126 detection width intersects equal to second laser radar detection plane 126 with ground (ground is assumed to be horizontal plane)
Length.
In other embodiments, second laser radar module detection plane 126 is on the basis of foregoing description and can be with
Move up and down or inclined, only need second laser radar module 12 to realize the above-mentioned function of the present embodiment or/and meet this reality
