Background

The total station, namely a total station type electronic distance meter (Electronic Total Station), is a high-technology measuring instrument integrating light, mechanical and electrical functions, and is a surveying instrument system integrating horizontal angle, vertical angle, distance (inclined distance and flat distance) and height difference measuring functions. Compared with an optical theodolite, the electronic theodolite changes the optical dial into a photoelectric scanning dial, and replaces manual optical micrometer reading with automatic recording and displaying reading, so that the angle measuring operation is simplified, and reading errors can be avoided. The total station is called because it can complete all the measurement work on the station by setting the instrument at one time. The method is widely applied to the fields of precision engineering measurement or deformation monitoring such as ground large-scale building and underground tunnel construction.

The operating principle of the total station is approximately as follows: the total station emits light beams to the prism through a laser or red line emitter, and then the light beams are reflected back through an inverse prism. The computer inside the total station calculates the coordinates of the target according to the angle and distance of the light rays and stores the data in the memory. By constantly measuring, three-dimensional coordinates of the object in space can be obtained.

Therefore, when the total station is used for measurement, a measuring person needs to erect a total station machine at a known coordinate point, another measuring person erects the prism at a rear view point (point to be measured), and the mirror surface of the prism is ensured to face the light emitting end of the total station, so that the prism can well reflect infrared light emitted by the total station. The position of the prism is generally far away from the position of the total station, so that a measurer at the prism is difficult to see the specific condition of the total station, the measurer at the total station is often required to remotely guide the measurer at the prism through the interphone to adjust the position of the prism, the process not only tests the command capability of the measurer at the total station, but also needs to have higher direction sensing and understanding capability, and the communication between the two measurer is slightly problematic, so that the adjustment time of the prism can be prolonged, and the measurement efficiency is reduced.
