Optical axis is parallel with center line;
(2) area of section is measured,
By the optical axis comprising range finder using laser and be parallel to the plane on ground and intersect formed curve institute with dump
The plane surrounded, is defined as cross section;Now the area in cross section is S1, including left region measurement and right region measurement;
Setting up rectangular coordinate system, i.e. make a plane being perpendicular to described cross section comprising blueline, it is with described
The intersection in cross section is x-axis;Make a plane being perpendicular to described cross section comprising center line, itself and described cross section
Intersection is y-axis;
Main control software in computer sends instruction, starts range finder using laser and carries out laser ranging, laser ranging
The laser that machine is launched advances along its optical axis, forms laser ranging line;When laser ranging line runs into obstacle,
Measure distance value k0;
Startup is just being swept the main control software in program, i.e. computer and is being sent instruction, controls rotating shaft and drives sharp clockwise
Ligh-ranging machine rotates, and rotates every timeAnd find range, then when n-th rotates, the angle turned over
The distance recorded is k+n;The main control software these data being sent in computer carries out availability deciding, to
Rotating for n time, its critical distance isThe length that i.e. laser ranging line intersects with x-axis;
Wherein, d is first rotating shaft distance away from coal yard left head of district limit;W is the rectangular zone width of coal yard;
IfIllustrating that laser ranging point has got to dump, point distance measurement is effective, now this survey
Being defined as characteristic point away from point, the coordinate calculating characteristic point is:
IfIllustrate that laser ranging Xian You district does not has dump through place, i.e. point distance measurement without
Effect, is now defined as characteristic point by the intersection point of laser ranging line Yu x-axis, and its coordinate is:
Run into for the first time when if n-th rotates point distance measurement invalid after, then again meet when rotating for (n+1)th time
Invalid to point distance measurement, illustrate to have passed over the scope of right district dump, terminate along inswept journey;Now, will be final
Number of revolutions n is designated as N1;
Start the main control software in homing procedure, i.e. computer and send instruction, control rotating shaft and drive sharp counterclockwise
Ligh-ranging machine turns to its optical axis and overlaps with y-axis, i.e. initial position;
Start and counter sweep program, i.e. main control software in computer sends instruction, controls rotating shaft and drives sharp counterclockwise
Ligh-ranging machine rotates, and rotates every timeAnd find range, then when n-th rotates, the angle turned over The distance recorded is k-n;The main control software these data being sent in computer carries out availability deciding,
Rotating n-th, its critical distance isThe length that i.e. laser ranging line intersects with x-axis;
IfIllustrating that laser ranging point has got to dump, point distance measurement is effective, now this survey
Being defined as characteristic point away from point, the coordinate calculating characteristic point is:
IfIllustrate that laser ranging Xian You district does not has dump through place, i.e. point distance measurement without
Effect, is now defined as characteristic point by the intersection point of laser ranging line Yu x-axis, and its coordinate is:
Run into for the first time when if n-th rotates point distance measurement invalid after, then again meet when rotating for (n+1)th time
Invalid to point distance measurement, illustrate to have passed over the scope of right district dump, anti-inswept journey terminates: now, will be final
Number of revolutions n is designated as N2;
Be again started up homing procedure, i.e. main control software in computer sends instruction, controls rotating shaft and carries clockwise
Dynamic range finder using laser turns to its optical axis and overlaps with y-axis, i.e. initial position;
All of characteristic point being linked in sequence, form a broken line, the region that broken line and x-axis surround is by some ladders
Shape cell area forms, and can regard the cross section area S in right district part approx asright;It is calculated as follows this region
Area:
Left region measurement is just the same with right region measurement, and similarly, available cross section is at the area S of left district partleft;
Then there is area of section S1=Sright+Sleft;
(3) move in synchronization, it may be assumed that
Main control software in computer sends instruction, Synchronization Control sliding platform vertically z move up away from
From h, now the optical axis of range finder using laser is h with the vertical dimension on ground0+h;
(4) repeating step (2), now the area in cross section is S2;
(5) repeating step (3) and (4), now the optical axis of range finder using laser with the vertical dimension on ground is
h0+ 2h, the area in cross section is S3;
(6) constantly repeat step (5), respectively obtain S4,…,Si,Si+1... until the area of section S recordedM+1
Little area value set in advance less than one;
(7) step (1) is repeated;
(8) dish coal calculates, it may be assumed that
Main control software in computer retains area of section from S1To SM;Regard the volume of dump as some
The volume sum of individual stratiform volume element, is calculated as follows the volume of dump
