A question about total stations, questions about total stations

Check if there is a problem with the instrument parameter setting!

There is no problem with the prism constant!

Grid factor settings are not!

Prism check no!

The prism is high, the instrument is high, right!

That's too much, did you measure the high value of your instrument?

Summary. Total station related problems: Hello dear, your situation should be something wrong with the instrument's program. As we all know, the value range of the azimuth angle is [0,360], you ** in the hr display number, itself is not normal, DHR is the difference between the current line of sight azimuth and the azimuth angle to be staked, so the value range will not be greater than 360 degrees, so this is a problem with the instrument itself.

The total station is an electronic product, built-in calculation program system, so there is a certain probability of failure, in this case, it is recommended to shut down and restart first, to see if the fault is eliminated, it is really not possible to remove the battery and reinstall it. If the fault persists or the same fault occurs frequently, then it is time to find a professional repairman to repair it.

The total station, that is, the electronic total station, is a high-tech measuring instrument integrating light, machinery and electricity, and is a surveying and mapping instrument system integrating horizontal angle, vertical angle, distance (oblique distance, flat distance) and height difference measurement functions.

Key features of the total station:

1. Angle measurement function: measure horizontal angle, vertical angle or zenith distance;

2. Ranging function: measure the horizontal distance, oblique distance or height difference;

3. Tracking measurement: that is, tracking ranging and tracking angle measurement;

4. Continuous measurement: angle or distance are measured continuously or continuously at the same time.

It is mainly used in construction:

1. Distance lofting.

The difference between the design distance and the actual distance can be compared, and the design distance can be quickly put into the field.

2. Coordinate lofting.

If the coordinates of the instrument point and the coordinates of the backsight point are known, or the coordinates of the instrument point and the azimuth angle of the backsight are known, the three-dimensional coordinate lofting can be carried out, and the coordinate transformation can also be carried out if necessary.

The following is the stakeout process for the total station:

1. Set up a station. Instruments are placed on the control points and aligned.

Set the station parameters, enter the station coordinates, and the instrument height.

2. Orientation. > telescope is aimed in the rear-looking direction.

Set the backsight parameters and enter the backview coordinates.

After completing the view, you can directly measure the coordinates of the backsight point as a check.

3. Lofting. > select the lofting function in the menu (most instruments are in the main menu).

Enter the coordinates of the lofting point, and the instrument will display the distance and angle parameters after confirmation.

Turn the telescope according to the display prompts, and fix it when the horizontal angle deviation is 0.

Instruct the prism runner to walk in the direction of the line of sight, and estimate where he should go according to the distance given by the instrument.

Measure once. The instrument will show the difference in distance, generally negative numbers indicate a move in the direction of the total station total station, and positive numbers move in the opposite direction.

Measure again. Repeat this step until you know that the distance difference meets the requirements.

This is the point to be staked, measure the coordinates, and record.

Extended Materials. Total station, that is, total station electronic rangefinder (electronic

TotalStation) is a high-tech measuring instrument integrating light, machinery and electricity, and is a surveying and mapping instrument system integrating horizontal angle, vertical angle, distance (oblique distance, flat distance) and height difference measurement functions. Compared with the optical theodolite, the electronic theodolite replaces the optical dial with a photoelectric scanning dial, and replaces the artificial optical micrometer readings with automatic recording and display of the readings, which simplifies the operation of angle measurement and avoids the generation of reading errors. Because it can complete all the measurement work on the station by placing the instrument at one time, it is called a total station.

It is widely used in the field of precision engineering measurement or deformation monitoring such as large-scale above-ground buildings and underground tunnel construction.

With the continuous development and application of computer technology, as well as the special requirements of users and the application of other industrial technologies, a new period of development has emerged in the total station, and there is a total station with memory, waterproof, explosion-proof, computer and so on.

The world's most accurate total station: angle measurement accuracy (standard deviation of the direction of a return) seconds, ranging accuracy.

Using ATR (Auto

targets

recognition, automatic target recognition) function, which works both day and night (without lighting). Total stations have achieved unbelievable accuracy in angle and distance measurements, can be operated manually or automatically, can be operated remotely from a distance or under the control of an on-board application, and can be used in applications such as precision engineering measurements, deformation monitoring, and mechanically guided control with virtually no tolerance.

A total station is one that can automatically measure angles and distances, and can transmit the measurement data to the corresponding data collector according to a certain program and format. The total station has a high degree of automation, many functions and good accuracy, and the measurement data collected in the field can be directly entered into the computer for data processing or into the automated drawing system by configuring the appropriate interface. Compared with the traditional method, a large number of intermediate manual operation links are omitted, so that the labor efficiency and economic benefits are significantly improved, and the defects of high error rate in the process of manual operation and recording are also avoided.

Working characteristics of total station:

1. It can measure angle and distance at the same time and automatically record measurement data;

2. There are various field applications, which can get the calculation results at the measurement site;

3. It can realize data flow;

Total station: total station type electronic rangefinder.

In the first station, the measurement of the three basic elements of observation is completed: height difference, distance and angle. Because all the basic elements have been observed in this way, it is called a total station.

The measurement is a separate work of angle measurement, edge measurement, and level, and it is necessary to set up stations when carrying out, and use theodolite, rangefinder, and level respectively. The total station means to set up a station for them and use one instrument to carry out these tasks at the same time.

All of them can be operated standing up, and the functions of the original theodolite, rangefinder, and level are concentrated, and the three-dimensional data can be directly input and output by the keyboard.

The total station measures angles and coordinates. Help you find the buildings and facilities on the drawings in the actual location, which is mainly to build according to the drawings. Or help you redraw the facilities and buildings in the actual geographical location to the drawings, which is the later acceptance and review.

The data measured by the total station is: angle and distance.

However, through the built-in program, the measured angle and distance can be calculated to the horizontal coordinates and other data, thus simplifying the labor of human calculation, and eliminating the error of human calculation, on the construction site, he is mainly used to do construction lofting, and the points on the design drawings are calibrated on the ground.

To put it simply, a total station is like a pen, which can draw the appearance of the designed building on the site by positioning and measuring points one by one, and connecting those points into lines. It is an instrument for construction positioning.

The total station is actually an advanced measuring instrument that integrates the level and theodolite, and it is necessary to look backward when it is used, that is, to find a reference edge and point, and then realize the plane position and elevation of the total station to measure the object through the angle and distance from the reference position, and it can also be turned around to loft the plane and elevation position of the design into the actual position, which is the lofting on the construction, that is, the drawing design position is lofting to the actual position in the construction through the total station.

Generally speaking, the use of total station:

1.Know the basic measurement methods and procedures (if you've never been exposed to it before, it's best to ask your friend to take a few minutes to talk about it briefly).

2.Learn how to take and store. As well as the erection of total stations, alignment and parity.

3.Data acquisition. Learn about wire, fragment and clutter measurements.

4.Specific angle and ranging. Sketch it.

5.Data transmission.

6.Drawings, print data and drawings.

7.Pay attention to the handling and storage of the total station. Keep the instrument as clean and dry as possible.

If you want to know the specific operation and application of the instrument, you can go to a specific model. However, the basic operating requirements of each instrument are much the same. Or email me a common **.
