Who has the steps and methods of total station pay off measurement, please send it to me

Connecting the power supply -- setting up the instrument -- turning on the machine -- taking a rear view -- selecting and lofting -- transmitting coordinates -- setting the zero angle -- ranging -- piling -- is a bit one-sided because the total station is not only the lofting function. There is also data acquisition, angle measurement, ranging, area measurement and advanced lofting software combined. Of course, you have to combine various methods of calculating coordinates to calculate the coordinates, so that's all.

The total station measures the specific steps for closing the wire.

1. Measure each angle and distance.

2. Calculate the internal calculation, calculate the closing difference, and then if the limit is met, the reverse number will be distributed according to the number of inner corners.

3. Calculate the corrected azimuth.

4. Coordinate increment calculation.

5. Obtain the coordinates of each point, the total station is attached to the wire is inverted and measured, and the specific steps of the direction of rotation of the instrument

The wire turn angle is divided into left and right corners

Left Corner: The horizontal angle to the left of the traverse direction is called the left corner.

Right Corner: The horizontal angle to the right of the traverse direction is called the right corner.

Observation direction is less than.

When there are 3 directions, the direction observation method is used for the traverse, and the upper half of the rounding: first observe the horizontal angle of the front mirror (disk left) of the rear viewpoint, rotate the horizontal dial clockwise to illuminate the front sight point, and observe the lower half of the horizontal angle of the front mirror (disk left): first observe the horizontal angle of the front view point inverted mirror (disk right), rotate the horizontal disk counterclockwise to illuminate the rear sight point, and observe the horizontal angle of the back sight point of the inverted mirror (disk right).

When measuring, there is little difference between it and the theodolite steel ruler wire, which is both angle measurement and edge measurement.

Specific steps: 1. Use the angle measurement function of the total station to measure the polygon inner angle of the closed wire with the rounding method, and then measure the horizontal angle between an edge and a known edge;

2. Use the ranging function of the total station to measure the horizontal length of the polygon edge.

3. Sum the inner angles of the polygon i, subtract the sum of the theoretical internal angles of the polygon (n-2) 180°, and obtain the angle closure difference f.

4. If the angle closure difference does not exceed the limit, correct the inner angle of the polygon. vi=-f n, correction = i+vi (evenly distributed).

5. Calculate the coordinate increment.

6. Find the closing difference of the full length of the wire and assign it.

7. Correct the coordinate increment.

8. Find the coordinates of each point.

The total station can be measured directly by closing the conductor and measuring the conductor, without the need for intermediate stations. The same goes for goniometry. The specific distance and angle measurement requirements need to refer to the "Engineering Survey Specification" according to the accuracy level of your wire.

Only when you understand the basics of measurement should you know what wire measurement is all about.

There are some differences in the program instructions of different instruments, and the steps are the same.

1.Angle measurement (be sure to measure the left turn angle of the line, which is exactly the inner angle of the polygon at this time, which is convenient for verification), and edge measurement (it is very easy to measure the edge of the total station, just take the average), these two items are necessary field work.

2. Internal calculation. Check whether the limit is exceeded first.

Step 1: Angle. The difference angle and (n-2)*180 ratio, the difference does not exceed the limit, even if the coordinate azimuth:

Front angle (the angle of the forward direction is the front angle) back angle (known edge) + left turn angle + (or) 180 (the first two terms and the excess are subtracted, and the number of corrections (equal to the negative difference divided by the number of edges n), to see if the final calculated value is equal to the known edge.

Step 2: Distance (use the corrected value when it comes to azimuth). The azimuth angle of the side length * cos coordinates, n is calculated as the difference in the x direction; The azimuth angle of the side length *sin coordinates, n is calculated as the difference in the y direction.

Let l = root number (x square + y square), find k l s (sum of all side lengths, and then take the whole meter). Compare whether the k-value exceeds the limit. If the limit is not exceeded, the coordinates are calculated.

x front x back + side length * cos coordinate azimuth + correction number (difference s in the negative x direction s * side length).

Before y and after y + side length * sin coordinate azimuth + correction number (the difference in the negative y direction s * corresponding to the side length), use this formula to find the starting point coordinates, and compare whether it is consistent. Its practical Excel is much more convenient.

Measurement Situation:

Close the wire A-B-C-D-E-F-A, use the total station to frame the instrument at point A, point F and point B respectively, read the reading of the horizontal dial, subtract the reading (not enough to add 360°), measure the right side of the plate again, and calculate the angle as well. Average the angles.

Then each point frame instrument measures the distance between each side.

The angles of the known edges are then measured.

Total Station Measurement Closed Traverse Steps:

1. Measure each angle and distance.

2. Calculate the closure difference in the industry, and then if you meet the limit, you will be assigned 3 according to the number of inner angles, and calculate the corrected azimuth angle.

4. Coordinate increment calculation.

5. Get the coordinates of each point.

The total station traverse measurement steps are not complicated, the following explains the detailed measurement method, the specific steps are as follows:

1. After arriving at the designated observation point, first of all, adjust the legs of the total station smoothly, and observe the position of the disc of the finger (red box) in the figure, as long as the inside is kept in the center position.

2. The next step is to adjust the upper part of the total station to keep it balanced, and observe whether the middle ball located in the red frame is in the middle, and it meets the requirements if it is in the middle.

3. Adjust the position of the red frame in the figure again, rotate the knob with your fingers, and be careful not to touch the bracket on the lower side, so as not to readjust the bracket.

4. When the upper part is adjusted, then press the main menu button, follow the prompts on the display to perform the next operation, and select lofting.

5. The next thing is to observe and adjust, use the knob to adjust, this time the part to be adjusted is the lens, pay attention to the lens to be able to see clearly.

6. Finally, you can read and record, here we should pay attention to the flexible use of front and rear view, and the rest is to put the anti-rod point. In this way, the total station wire measurement is complete.

Dear, glad to answer for you. Total station is a high-precision measuring instrument that is widely used in construction, civil engineering, road construction and other engineering surveying fields. In measuring pay-off, total stations have the following applications:

Pay-off measurement: The total station can be used for pay-off work, that is, marking the measurement point at a specific location on the ground. By setting the coordinates of the target point on the total station, the surveyor can accurately mark the target point on the ground to guide the subsequent engineering construction or measurement of the amount of jujube acacia.

Building layout: In building construction, total stations can be used for the layout and positioning of buildings. By measuring the corners and control points of a building, the total station can help construction benches and construction crews ensure that the location, angle, and dimensions of the building meet the design requirements.

Road construction: Total stations also have important applications in road construction. It can be used to measure road axes, side slopes, and intersection locations to ensure accurate layout and flatness of the road.

Earthwork quantity calculations: Total stations can be used to measure terrain elevations and volumes in earthworks. By measuring the elevation of a series of points on the ground, the total station can generate a topographic map and calculate the volume and profile of the earthwork.

Monitoring deformation: In civil engineering, total stations can also be used to monitor the deformation and displacement of structures. By regularly measuring specific points in a structure, a total station can provide accurate displacement data that helps engineers assess the safety and stability of the structure.

Total station coordinate lofting, construction line surveyor to take you to use the total station.

For the precautions when the total station is released, say the following:

1. It is best to work in a group of three people, one person is responsible for reading the picture and operating the instrument, and the other two people cooperate to determine the location (one person can put paint, pencils, stakes, nails, hammers, and walkie-talkies into the tool bag to carry, and the other person moves the prism);

2. The prism should be inspected after a period of use, when the prism bubble is centered, long-term use may cause the lower iron tip of the prism rod and the center of the prism to not be on the same plumb line, resulting in an error when aiming;

3. The prism should face the direction of the total station to avoid the inability to reflect the signal;

4 During intervals, the instrument should be in the goniometric mode, because the ranging mode will consume too much battery power.

Measuring pay-off is a job that requires a high sense of responsibility, and self-inspection should be carried out after the measurement work is completed.
