1, Total Station Introduction
1. The concept of Total Station
Called the Total Station Total Station Electronic Tachometer. It consists of optical range finders, electronic theodolite, microprocessors, power devices and reflective prisms etc., is a set of automatic measuring angle, ranging, measuring height in one, is to achieve the automatic acquisition of measurement data, display , storage, transmission, recognition, to handle calculations of three-dimensional coordinate measuring and positioning system. Because only placement - * sub-devices can be the completion of this station all of the measurements, it is called "Total Station."
Total Station is widely used in control surveying, topographic surveying, cadastral and real estate surveying, engineering lofting, installation surveying, offshore positioning deformation observation and measurement of aspects of work. Measured inside and outside the industry in achieving integration of engineering, automation, intelligent critical hardware systems.
2. Total Station accuracy and structure of
Many different types of total station, according to angle measurement accuracy is divided into 0.5 ", 1.0", 1.5 ", 2.0", 3.0 ", 5.0" and 7.0 ", etc. level. according to the structure can be divided into two groups combined and the overall style. Combined Total Station Total Station is an early product, which is from the electronic theodolite and distance meter combined composition, can be divided into the two can be combined. operating hours , DME is installed in the electronic theodolite, compared with 10000 cable between the data communications, operations after the end of the respective unloaded crates. such equipment in accordance with operational precision, by the user to choose a different angle measurement, distance measurement equipment be combined, good flexibility. current production of the total stations are mostly monolithic electronic total station, which is the electronic theodolite, range finders and microprocessor integrated, sharing a telescope and installed in the same enclosure as a whole can not be separated. field measurement data collected by the machine memory, automatic storage, operation is completed through the communication cable to connect the host computer for data transmission. This instrument is reliable and convenient.
The world of the equipment manufacturers to produce various types of total stations, but more and more varieties of precision higher and higher. As electronic technology and computer technology continues to evolve and application, there has been with the memory type, water-based, computer-based and other types of total stations, and the increasingly high degree of intelligence to provide users with greater convenience to .

           Figure 10-1-1 for the Leica produced by TC (R) 802-type total station, the angle measurement accuracy is 2.0 ", ranging accuracy of ± (2 +2 × 10-6D) mm, ranging scope of a ~ 3500m (single prism) can be automatically axis (vertical axis, horizontal axis, depending on the quasi-axis) compensation. manufacturers with the software listed in Table 10-1-1, some of which basic software already installed in the instrument factory, and the other Some senior software sold separately. basic software required for the provision of general basic measurement functions, then the set of advanced software control surveying, construction surveying, road lofting, adjustment calculations, digital mapping and other features and integration. has the character prompts guide, limit Poor automatic review of nuclear and overloaded functions when prompted, to a variety of levels and network-based control survey data collection, inspection, pre-processing, calculation of estimates and strict adjustment may apply to be completed by the total station automatically.
