Problems solved by technology

The movement of the foot pad will affect the accuracy and reliability of the leveling measurement. However, the existing structure of the foot pad will cause the surveyor to not notice it immediately after the movement of the foot pad. For correction, the measured results can only be invalidated, and re-measured from the starting point to the end point, which directly affects the work efficiency of the leveling survey

Abstract

The invention discloses an intelligent leveling measuring scale pad capable of effectively improving leveling measuring efficiency. The intelligent leveling measuring scale pad is provided with a transverse base plate (1); supporting feet (2) are arranged below the transverse base plate (1); a scale support (3) is arranged above the transverse base plate (1) and the top end of the scale support (3) is a spherical surface; a column-shaped cabin body (4) is arranged between the transverse base plate (1) and the scale support (3); an infrared reflection type photoelectric sensor (5), a scale paddisplacement detection device (6), a warning device (7), a controller (8) and a battery (9) are arranged in the column-shaped cabin body (4); the infrared reflection type photoelectric sensor (5), thescale pad displacement detection device (6), the warning device (7) and the battery (9) are connected with the controller (8) respectively; and an emitting optical axis of the infrared reflection type photoelectric sensor (5) is orthogonal in the ground.

Description

technical field [0001] The invention belongs to the technical field of geodetic and engineering surveying, in particular to an intelligent leveling pad which can effectively improve the efficiency of leveling. Background technique [0002] The traditional level measuring device is composed of a level gauge and a level rod. When measuring, first place the two leveling rods at two points A and Z on the ground (called leveling points), then set the level at the middle position of the two points, and use the horizontal line of sight of the leveling instrument telescope to aim and read Take the elevation values ​​of two leveling rods, and the difference between the measured elevation values ​​is the level difference between two points A and Z on the ground. If the elevation of one point (such as A) is known, the other point can be calculated from the height difference (such as Z) elevation. Usually, it is known that benchmarking point A is far away from target benchmarking poin...
