Collection data are simultaneously filtered, and obtain valid data.There are two numerical value for every group of data of obliquity sensor output, are respectively
Orthogonal X/Y angle-data.
2, the mathematical model of equipment leveling
During equipment leveling, the rotation of three castors will drive the height of castor point to change, and then make to set
Standby horizontal sextant angle changes.Want to reach quick and precisely level device, needs to establish a reasonable effective mathematical model
To calculate the method for operation of three castor motors.
The mathematical model of equipment leveling as shown in Figure 3, equilateral triangle three vertex O, A, B respectively represent three castors
(mechanical structure feature), point M are the midpoints of side OA, and line segment BM is the perpendicular bisector of side OA.Obliquity sensor is fixed on equipment to put down
On face, and make X-axis forward direction identical as the direction OA, Y-axis forward direction is identical as the direction line segment MB.
When the mathematical model is placed in horizontal plane, obliquity sensor X, Y-axis output data should be 0.
3, control process is leveled
As shown in figure 4, triangle OAB is triangle OHG, the extension of the extended line and BA of GH in the upright projection of horizontal plane
Line meets at point P, connects OP, and the extended line and OP of BM intersects at point D, GD and OH and intersect at point N.

Angle, i.e. the output angle angle value of obliquity sensor X-axis.∠ BDG is the angle of DB and horizontal plane, that is, obliquity sensor Y
The angle of axis and horizontal plane, i.e. the output angle angle value of obliquity sensor Y-axis.
(2) in right angled triangle OAH, ∠ AOH is the angle of OA and horizontal plane, then AH can be equivalent to castor point A with
Castor point A is reduced height value h, the horizontal sextant angle of X axis can be adjusted to 0 value by the difference in height h of horizontal plane.
(3) according to the analysis of step (2) as a result, starting point A castor motor rotation, reduces invocation point A by height.Turn in motor
During dynamic, the ∠ AOH angle value for the moment to judge to be obtained by obliquity sensor data, when the angle value becomes 0 value, explanation
Point O and point A is in and is same as on horizontal plane, and equipment in the X-axis direction, has reached horizontality at this time.
(4) after reaching horizontality in the X-axis direction, point A, P, H will be overlapped as a bit, point M, D, N will be overlapped as a bit.
Here still with signal map analysis above, in right angled triangle BGD, ∠ BDG is the angle of DB and horizontal plane, that is, inclination angle
The angle of sensor Y-axis and horizontal plane reduces castor point B then BG can be equivalent to the difference in height h of castor point B and horizontal plane
The horizontal sextant angle of Y-axis can be adjusted to 0 value by height value h.
(5) according to the analysis of step (4) as a result, starting point B castor motor rotation, reduces invocation point B by height.Turn in motor
During dynamic, the ∠ BDG angle value for the moment to judge to be obtained by obliquity sensor data, when the angle value becomes 0 value, explanation
Point B is on horizontal plane, and equipment in the Y-axis direction, has also reached horizontality at this time.
