It is a surveying and mapping instrument system integrating horizontal angle, vertical angle, distance (slant distance, horizontal distance) and height difference measurement functions. Compared with the optical theodolite, the electronic theodolite replaces the optical degree plate with a photoelectric scanning degree plate, and replaces the manual optical micrometer reading with automatic recording and display of readings, which simplifies the angle measurement operation and avoids the occurrence of reading errors. The tripod is the supporting structure of the surveying and mapping instrument. When in use, the total station is installed on the tripod, and then the bracket on the tripod is supported on the ground, and then the tripod is adjusted to make the total station in a horizontal state, and the building is inspected by the total station.

The setting of multiple level instruments is convenient for observation from multiple directions, and they are arranged in a circular array. The three level instruments are respectively arranged between two adjacent support rods 21 and are located at the bottom end surface edge of the mounting base 1. A groove 8 is provided on the outer side of the mounting base 1, and a support assembly 2 is provided inside the groove 8. The support assembly 2 includes a support rod 21 rotatably connected to the inside of the groove 8, a round rod is fixedly connected to the inside of the groove 8, and the support rod 21 is rotatably connected to the outside of the round rod. A moving hole 22 is provided on the support rod 21, and a micro motor 23 is fixedly connected to the inner top wall of the moving hole 22. A battery is installed on the inner surface of the upper end of the support rod 21, and the battery supplies power to the micro motor 23. The battery is electrically connected to the micro motor 23, and the output end of the micro motor 23 is fixedly connected to a screw rod 24;

[0030] The micro motor 23 is controlled to drive the screw rod 24 to rotate, and the screw rod 24 rotates to drive the supporting foot 25 inside the movable hole 22 to move, thereby automatically adjusting the length of the supporting foot 25 extending out of the outside of the support rod 21. A sliding hole 26 is provided on the inner bottom wall of the movable hole 22, and the supporting foot 25 is slidably connected inside the sliding hole 26. The supporting foot 25 is composed of an integrally formed vertical rod and a pointed cone. The pointed cone is fixedly connected to the bottom end of the vertical rod. A threaded connection hole is provided in the middle of the vertical rod, and the supporting foot 25 is threadedly sleeved on the outside of the screw rod 24. The supporting foot 25 is threadedly sleeved on the outside of the screw rod 24 through the threaded connection hole. The length of the screw rod 24 threadedly inserted in the threaded connection hole is half the length of the vertical rod. The top of the mounting seat 1 is detachably connected to a mounting block 5, and the top of the mounting block 5 is fixedly connected to the total station body 3.

The outer side of the supporting foot 25 is symmetrically fixedly connected with a slide plate 251 adapted to the slide groove 221. The cooperation between the slide plate 251 and the slide groove 221 further limits the supporting foot 25. When the supporting foot 25 moves, the supporting foot 25 drives the slide plate 251 to move inside the slide groove 221, thereby improving the stability of the supporting foot 25 when moving.
