Key points: the basic operation of total station instrument, the principle and operation method of angle measuring, edge measuring, 3D coordinate measuring and 3D coordinate setting out. Difficulty: the principle and operation method of total station measuring 3D coordinate and three-dimensional coordinate setting out. Teaching methods: take demonstration teaching. Explain the Topcon total station, each speaking a function in the classroom, using the advantages of multimedia classrooms, a live demonstration, and the operation process through the projector to the screen, the visual effect, so that students can quickly grasp the use of total station. Section 7.1 of total station (total station) function introduction With the continuous development of science and technology, the electronic speed measuring instrument (short for total station), which is made up of photoelectric range finder, electronic theodolite, micro processor and data recording device, is becoming more and more mature and gradually popularized. This marks the level of research and mapping instruments, manufacturing technology, scientific and technological content, applicability and so on, have reached a new stage. Total station refers to the automatic measurement of angle and distance, and can according to certain procedures and formats to transmit measurement data to the corresponding data collector. The total station instrument has a high degree of automation, many functions and good accuracy. By
