According to shown in Figure 2, described vertical circle is shaped as 1/4 circle.Described gage is scalable gage, and the adjustable in length scope is 0.5m to 2m.Described gage is free movable in 0 ° to 90 ° in the vertical direction.

According to shown in Figure 4, equipment frame is located near the dangerous point to be measured, the known point A of total powerstation is set up in the alignment clamp aiming, make horizontal dial zero setting, the gage end is placed on the tested point 0, recording level angle, vertical angle and gage reading record the position coordinate of interim some B again with total powerstation, can obtain the position coordinate of dangerous point O to be measured according to trigonometric conversion relation.

According to shown in Figure 4, in the practical application, use the utility model to cooperate the process of total powerstation mensuration tested point position coordinate as follows:

1, field data collection

1) settles aided measurement device

The utility model is installed on the tripod, uses pedestal will install leveling, utilize the alignment clamp on the horizontal dial to aim at the known point A that sets up total powerstation, make 0 ° of scale on the horizontal dial aim at known point; Horizontal direction is rotated vertical circle, and the gage end points is placed on the tested point O point.

2) measurement point data acquisition

A sets up total powerstation at known point, adjusts the riding position of aided measurement device, makes prism to be placed in interim some B and the known point A intervisibility that sets up total powerstation on the tripod of interim point, records the coordinate of interim some B.

3) information record

The data that need record: tested point period; Interim some period and coordinate; Known point period and coordinate; Horizontal angle beta; Vertical angle θ; The length S of gage;

Wherein, the reading of pointer indication, i.e. ∠ ABO on the horizontal dial when horizontal angle beta refers to that gage end points O point places tested point point to go up; The reading of pointer indication on vertical circle when vertical angle θ refers to that gage end points O point places tested point point to go up.

2, interior industry data are handled

1) the azimuth angle alpha AB of calculating AB

Position angle definition: to the angle that measures along clockwise direction on the survey line, be called the position angle of this straight line by the north.Its scope is 0 ° to 360 °, and the concrete computing method of the azimuth angle alpha AB of AB are as follows:

Calculate increment of coordinate Δ XAB and Δ YAB on directions X and the Y-direction at first, respectively:

ΔXAB＝XB-XA

ΔYAB＝YB-YA

Secondly, the arc-tangent value of coordinates computed increment: α AB is sharp

Judge the quadrant at α AB place by the sign of XAB and Δ YAB, obtain the azimuth angle alpha AB of AB:

Δ XAB＞0 and Δ YAB＞0 item are first quartile; α AB=α AB is sharp;

Δ XAB＜0 and Δ YAB＞0 item are second quadrant; α AB=180 °-α AB is sharp;

Δ XAB＜0 and Δ YAB＜0 item are third quadrant; α AB=180 °+α AB is sharp;

Δ XAB＞0 and Δ YAB＜0 item are fourth quadrant; α AB=360 °-α AB is sharp;

Δ YAB=0 and Δ XAB＞0 a α AB=0 °;

Δ XAB=0 and Δ YAB＞0 a α AB=90 °;

Δ YAB=0 and Δ XAB＜0 a α AB=180 °;

Δ XAB=0 and Δ YAB＜0 a α AB=270 °;

2) calculate BO azimuth angle alpha B0 angle

αBO＝αAB+180°+β

3) ask tested point O coordinate

ΔX＝S×cosθ×cosαBO；

ΔY＝S×cosθ×sinαBO；

ΔH＝-S×sinθ；

Then concern according to the position of tested point O and interim some B:

XO＝XB+ΔX；

YO＝YB+ΔY；

HO＝HB+ΔH；

The example that utilizes the utility model servicing unit specifically to measure:

1, field data collection

1) settles aided measurement device

2) information record

Record data are: O, and B, 3826127.732,472532.351,625.131,

A，3826275.637，472595.278，605.393，45°，30°，1.8。

2, interior industry data are handled

1) calculates AB azimuth angle alpha AB=246 ° 57 ' 9 ";

2) calculate BO azimuth angle alpha BO=111 ° 57 ' 9 ";

3) ask tested point O coordinate

XO＝XB+S×cosθ×cosαBO；＝3826127.732-0.583＝3826127.149

YO＝YB+S×cosθ×sinαBO；＝472532.351+1.446＝472533.797

HO＝HB-S×sinθ；＝625.131-0.9＝624.231。

That is: O point coordinate: X==3826127.149, Y=472533.797, horizontal H=624.231.
