Problems solved by technology

[0003] (1) Low measurement efficiency and reliability
[0004] Realizing the reasonable configuration of the position between the leveling instrument and the leveling rod in a complex terrain environment often consumes a lot of energy and time of the surveyors, which affects the measurement efficiency; using a leveling instrument for measurement, it is impossible to carry out multi-observation system for the measured height difference data In order to improve the reliability of leveling, the round-trip measurement and verific...

Embodiment 1

[0023] Such as figure 1 Shown: a cylindrical scale body 1 with a height of 2 to 4 meters made of metal, plastic or wood, etc., a leveling rod 2 parallel to the axis of the cylindrical scale body 1 is fixed on the same cylinder surface of the cylindrical scale body 1 (ordinary ruler 2) and the observation unit 3 that can slide up and down. A slide rail can be installed on the cylindrical scale body 1. The slider on the observation unit 3 slides up and down along the slide rail and can be adjusted according to the needs of different terrains for the height of the horizontal line of sight. fixed on the slide rail. Observing unit 3 has mutually fixedly connected and collimation axes parallel to each other's altitude signal measuring device 4, this side's height signal measuring device 5, and the other side's height signal measuring device 4 adopts the telescope with aiming function, is placed beside leveling rod 2, and its The line of sight is perpendicular to the leveling rod 2 ...

Embodiment 2

[0033] Such as image 3 , Figure 4 , Figure 5 Shown: basic structure is as embodiment 1, and what differs from embodiment 1 is that leveling staff 2 adopts indium steel barcode scale, and the other party's height signal measuring device 4 adopts the automatic leveling electronic telescope with aiming function, and the local height signal measuring device 5 A macro camera is adopted, and the lens is directed toward the leveling rod 2 , and the collimation axes of the other side's height signal measuring device 4 and the own side's height signal measuring device 5 are all perpendicular to the leveling rod 2 . The level 6 is a leveling monitoring device that is relatively fixedly connected to the observation unit 3. The leveling monitoring device uses a high-precision dual-axis inclination sensor (Refin HCA526T), and its two sensitive axes are perpendicular to the leveling staff 2, and one of them Parallel to the collimation axis of the opponent's height signal measuring devi...

Embodiment 3

[0043] Such as Figure 6 , 7 Shown: the basic structure is the same as embodiment 2, and the difference from embodiment 2 is that the height signal measuring device 5 of our side adopts a laser or an infrared distance measuring device, and its measurement axis is parallel to the axis of the cylindrical scale body 1, and the observation direction points to the column Shape scale body 1 bottom, the other party's altitude signal measuring device 4 adopts the electronic telescope that does not have automatic leveling function. Correspondingly, handles 10 are arranged on both sides of the cylindrical scale body 1, and the button 8 is fixed on the handle 10. The button 8 can be a key switch or an adjustment knob, etc., and the output of the button 8 is connected with the digital signal processor, and the display screen 9 is not limited to touch displays.

[0044] Work process is basically the same with embodiment 2, difference is as follows:

[0045] Placement of the instrument: ...

Abstract

The invention discloses a paired type observing ruler and gauge combined composite leveling instrument; the composite leveling instrument is provided with a column-shaped ruler body (1) and a level (6), wherein a leveling staff (2) and an observing unit (3) are fixed on the same column surface of the column-shaped ruler body (1); the leveling staff (2) is parallel to the axis of the column-shaped ruler body (1); the observing unit (3) can slide up and down; the observing unit (3) is provided with an opposite side height signal detector (4) and a home height signal detector (5), which are fixedly connected with each other; and a collimation axis of the opposite side height signal detector (4) is vertical to the axis of the column-shaped ruler body (1). Point-to-point direct leveling is truly realized; point selection and point arrangement are not limited by terrain environments; and leveling can be conveniently carried out in complicated geographic conditions, such as abrupt slopes, ditches, rivers, mountainous areas and so on.

Description

technical field [0001] The invention belongs to the technical field of surveying, and in particular relates to a dual-type observation ruler-meter-integrated composite level that can effectively improve the working efficiency and reliability of leveling surveys and is not restricted by the terrain environment. Background technique [0002] At present, the known leveling device is made up of a level and two leveling rods. When measuring, first place the two leveling rods on the ground at points A and B respectively, and then set the leveling instrument at the middle position of the two points A and B. In order to ensure the measurement accuracy, the horizontal distance between the leveling device and the two leveling rods is generally required. Equal or approximately equal. Use the horizontal line of sight of the leveling instrument to read the elevation values ​​of the two leveling rods respectively. The difference between the measured elevation values ​​is the level differ...
