Abstract

The invention relates to a multi-functional flat panel for teaching, which comprises mutually perpendicular base rulers and parallel rulers arranged at the bottom, a telescope is arranged on the top of the flat panel, a telescope with ruler is arranged on the observation part above the telescope, and a telescope with a ruler is arranged on one side of the telescope. There is a disc-shaped vertical dial, and a level bubble is fixed in front of the vertical dial. The design is precise and the operation is simple. It can fully demonstrate the principle and function of the flat panel, and is suitable for the practical teaching of surveying and mapping in civil engineering.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a flat panel for multifunctional teaching. Background technique [0002] Flat panel measurement is to directly measure and draw objects on the ground on the drawing after being scaled down. In the measurement, because the horizontal projection of the angle and the straight line is obtained by the graphic method, it is also called the graphic measurement. At present, in practical applications, flat panel instruments have been gradually replaced by total stations and GPS-RTK digital mapping. It is often used in teaching to teach basic measurement knowledge. [0003] The existing flat panel does not have a type specifically designed to explain its working principle, and it is often difficult to explain its working process to students clearly during the teaching process. Contents of the invention [0004] The object of the present invention is to provide a multifuncti...
