What is the difference between a total station, level and theodolite? It's been a long time today

In the completion of many engineering projects, many things cannot be implemented by making a guess and estimation out of thin air, so blind construction will cause a mistake. Therefore, when implementing some engineering projects, it is often completed with the help of some instruments. In civil engineering, there are actually many people who use various instruments to help people carry out measurements and assist in the construction. The most common instruments here are total stations, levels and theodolites. We all know that these instruments are various What's the role of it? What's the difference between them other than the name?

As the name suggests, the theodolite is somewhat similar to the latitude and longitude on our earth. Its function is to measure the angle, and it is an instrument that can measure the horizontal angle and the vertical angle. This principle is to measure two intersecting straight lines, and most of them are optical and electronic. However, this has certain limitations. It often requires a lot of staff to participate in the operation. The process is more complicated, and the efficiency is often not very high.

The last one is the level. When there is no such instrument, people use tubes to measure. Fill the tube with water, and then lead the tube to the two places to be measured. So now there is a level that measures the height difference between two points on the ground based on this principle. This use is that the height of the rear sight is the same and then there is a height, then this height is the height difference between the two points. Knowing the height of a certain point, this instrument can be used to calculate the height of another point.

Then it is a total station. Basically, the theodolite has all the functions it has. Compared with the theodolite, when measuring the angle, a function of measuring distance and calculation is added on the basis of the function, which can be collected by processing. Get everyone's good needs. Then what it has is a more high-precision angle measurement, which greatly reduces the preparation of a man's hands and improves a work efficiency. Therefore, the theodolite is basically useless now, and it has basically withdrawn from the market and the total station has become a mainstream.

In general, the total station is the best, more comprehensive, and more complete, but it still cannot replace the level. Well, do you think these instruments are amazing? Not to mention that they all use the same kind, is it shocking to say that there is such a difference.
