Problems solved by technology

[0003] The static leveling system in the prior art is composed of multiple levels. When in use, each leveling point can only measure the change in height of the point relative to the reference point. After the static leveling system is stabilized, the entire The system will form a water level internally, but the liquid level has not been calibrated, so the absolute elevation of the top of each bowl cannot be known immediately. If you want to obtain the elevation value of this point, you must perform a transfer station measurement, which is easy to cause errors Cumulative, heavy workload, poor precision

Embodiment 1

[0029] Absolute height level (such as figure 1 ), including a housing and a liquid level sensing sensor 6, the liquid level sensing sensor 6 is arranged in the housing, and the housing is divided into an upper housing 1 and a lower housing 11, the lower housing 11 is used to place the liquid 9; the upper housing The upper surface of the body 1 is provided with a reference seat 3 for placing the target ball 2;

[0030] In this embodiment, the reference seat 3 is a tapered ball seat, where various standard measurement target balls 2 can be placed on the reference seat 3 .

[0031] In this embodiment, the air pipe interface 7 is arranged at the upper end of the lower casing 11 , and the water pipe interface 8 is arranged at the lower end of the lower casing 11 .

[0032] Wherein, there are two gas pipe interfaces 7, which are respectively arranged on both sides of the lower housing 11;

[0033] In this embodiment, the lower housing 11 is provided with a temperature sensor insta...

Embodiment 2

[0035] In this embodiment, the absolute elevation level provided by multiple embodiments 1 is placed at the monitoring point and connected in series to form an absolute elevation level system (such as figure 2 ), the absolute elevation of each monitoring point can be obtained after the liquid level reaches a stable level. Wherein, the air pipe interface 7 and the water pipe interface 8 on one absolute height level are respectively connected to the air pipe interface 7 and the water pipe interface 8 on the other absolute elevation level through the gas connecting pipe and the liquid 9 connecting air pipe.

Embodiment 3

[0037] The using method of the absolute height level system, using the absolute height level system provided by embodiment 2, the method comprises the following steps:

[0038] S10, calibrating each absolute height level;

[0039] The method for calibrating each absolute height level is as follows:

[0040] S11, leveling the absolute height level;

[0041] S12. Add liquid 9 within the range of the liquid level sensing sensor 6 into the lower housing 11, and accurately calibrate the distance between the liquid level in the lower housing 11 and the center of the target ball 2 located on the outer reference surface of the upper housing 1. MD, obtain the height M of the liquid level in the lower casing 11 by the liquid level sensing sensor 6 simultaneously, the distance D=MD-M (such as figure 1 );

[0042] or

[0043] Accurately calibrate the distance MD between the liquid level in the lower casing 11 and the dome of the target ball 2 located on the outer reference surface of ...

Abstract

The invention discloses an absolute elevation level, an absolute elevation level system and a using method of the system, and belongs to the technical field of measurement, the absolute elevation level comprises a shell and a liquid level sensor, the liquid level sensor is arranged in the shell and divides the shell into an upper shell and a lower shell, and the lower shell is used for containing liquid; a reference seat for placing a target ball is arranged on the upper surface of the upper shell; the lower shell is provided with an air pipe connector and a water pipe connector. The settlement deformation of the monitoring area can be monitored, the absolute elevation of each monitoring point position can be obtained at any time without elevation transmission by taking the uniform liquid level at the stable moment as a reference, the operation is simple, and the accuracy is good.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to an absolute elevation level, an absolute elevation level system and a method for using the system. Background technique [0002] The static leveling system is a precision instrument for measuring relative elevation changes between two points or between multiple points, and measures the height difference between ground points according to the principle of leveling. [0003] The static leveling system in the prior art is composed of multiple levels. When in use, each leveling point can only measure the change in height of the point relative to the reference point. After the static leveling system is stabilized, the entire The system will form a water level internally, but the liquid level has not been calibrated, so the absolute elevation of the top of each bowl cannot be known immediately. If you want to obtain the elevation value of this point, you must perform a ...
