Description

Technical Field

[0001] This invention belongs to the field of tunnel monitoring technology, specifically relating to a total station target point aiming device and method based on ATR beam guidance. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Tunnel monitoring and measurement is an essential part of tunnel construction. Total stations are commonly used measuring equipment in this process, and after years of application and development, they have a mature technological system. Currently, total stations are gradually developing unmanned and intelligent application solutions. This approach reduces manual operation and improves the objectivity and accuracy of monitoring and measurement results. In this type of application, automatic aiming of the total station is a crucial step in achieving unmanned monitoring. Current total stations have some automatic aiming capabilities, allowing them to automatically align the eyepiece crosshairs with the center of the circular prism within a relatively small field of view according to a predetermined program. However, their aiming range is still limited, making it impossible to locate and align monitoring points with the target center within a larger field of view. Therefore, on-site personnel are still required during the total station's point-finding process. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a total station target point aiming device and method based on ATR beam guidance. This invention guides the total station to find the target monitoring point by remotely controlling the movement of the ATR beam, thereby completing unmanned monitoring work, reducing on-site personnel operation, and ensuring the safety of construction workers.

[0005] According to some embodiments, the present invention adopts the following technical solution:

[0006] In the first aspect, the present invention provides a total station target point aiming device based on ATR beam guidance.

[0007] A total station target aiming device based on ATR beam guidance includes: a laser emitting system, a telescope system, a beam splitting system, an ATR beam emitting system, and a CCD array, wherein the telescope system includes an objective lens and an eyepiece;

[0008] The ATR beam emitting system includes a remote-controlled gimbal and an ATR beam emitting probe. The front end of the remote-controlled gimbal is equipped with a component slot, and the ATR beam emitting probe is installed in the component slot.

[0009] The light emitted by the laser emission system is reflected by the monitored object and passes sequentially through the objective lens, the beam splitting system, and the ATR beam emission system before being projected onto the CCD array.

[0010] By remotely controlling the swing of the ATR beam emission probe, the total station's head movement is controlled, causing the center of the objective lens's crosshairs to move along with the center of the CCD array, thus aligning the ATR beam with the center of the CCD array and enabling the telescope's field of view to follow the beam.

[0011] Secondly, this invention provides a total station target point aiming method based on ATR beam guidance.

[0012] A total station target point aiming method based on ATR beam guidance, employing the total station target point aiming equipment based on ATR beam guidance described in Example 1, includes:

[0013] When the total station needs to find a target monitoring point and there is no monitoring point in the field of view, the ATR beam emission system is turned on, and the ATR beam mapping light spot appears on the CCD array;

[0014] The remote-controlled gimbal rotation of the remote-controlled ATR beam emission system generates relevant commands to the CCD array, adjusting the telescope's field of view so that the ATR beam coincides with the telescope's central axis. This, in turn, causes the center of the crosshairs to move the center of the CCD array, thereby aligning the ATR beam with the center of the CCD array and enabling the telescope's field of view to follow the beam.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention can guide the total station head to align with the center of the circular prism by using the ATR beam, thereby improving the automation level of monitoring using the total station and enabling unmanned monitoring inside the tunnel.

[0017] When the total station's aiming accuracy is insufficient, this method can be used for remote manual correction to improve the aiming accuracy of the total station's automatic monitoring, providing an application and solution for prism-free monitoring modes.

[0018] This invention enables monitoring personnel to remotely transmit aiming signals and guide the total station to find the target monitoring point without the need for manual follow-up, thereby completing unmanned monitoring and measurement tasks. Attached Figure Description

[0026] Example 1

[0027] This embodiment provides a total station target aiming device based on ATR beam guidance.

[0028] like Figure 1 As shown, a total station target aiming device based on ATR beam guidance includes: a laser emitting system, a telescope system, a beam splitting system 3, a CCD array 7, and an ATR beam emitting system 6. The laser emitting system is mounted on the objective lens 2 of the telescope system, and its main body is a laser emitting probe that can emit a strong laser beam to illuminate the monitored object.

[0029] The telescope system consists mainly of an objective lens 2 and an eyepiece 5. It allows observation of the monitored target, with the crosshairs aligned with the center of the circular prism 1 or reflector 4 at the monitoring point. The circular prism 1 is positioned at the tunnel monitoring point. Typical monitoring and measurement work involves observing changes in the position of the circular prism 1 to obtain information such as tunnel deformation. The circular prism 1 also serves as a receiver for the laser emission system, reflecting the laser emitted by the system to provide feedback on relevant information.

[0030] The aforementioned beam splitting system 3 can filter and classify the light reflected from objects, filtering natural light and infrared light, and selecting ATR beams for transmission and reflection onto the CCD array 7.

[0031] The CCD array 7 is the core component of the total station's automatic aiming system. Light rays, reflected by an object, pass through the objective lens 2 of the telescope system, are filtered and reflected by the beam splitter 3, and then projected onto the CCD array 7. The center of the crosshairs of the telescope objective lens 2 corresponds to the center of the CCD array 7. When their centers shift, a programmed mechanism maintains their alignment. Specifically, based on the sensitivity of the CCD array center to the ATR beam, the program determines whether a change in material properties occurs when the ATR beam passes through the CCD array center. If no change occurs, the program controls the gimbal to rotate and locate the CCD center. If a change in material properties occurs, the program is considered to have located the array center, thus preventing center shift.

[0032] CCD array 7 can identify the ATR beam. By programming, the ATR beam is always positioned in the center of CCD array 7. This is achieved by adjusting the telescope's field of view through motor rotation, aligning the ATR beam with the telescope's central axis, and then moving the center of the crosshairs to the center of CCD array 7, thus aligning the ATR beam with the center of CCD array 7.

[0033] like Figure 2 As shown, the ATR beam emitting system 6 includes a remote-controlled gimbal 8 and an ATR beam emitting probe 10. The remote-controlled gimbal 8 can rotate 360° under remote control, and its rotation angle can cover the entire CCD array 7. The front end of the remote-controlled gimbal 8 is equipped with a component slot 9, which can be used to mount a small beam emitter.

[0034] Specifically, the ATR beam emitting probe 10 is mounted on the front end component slot 9 of the remote-controlled universal joint 8 and can rotate with the remote-controlled universal joint 8. The front end of the ATR beam emitting probe 10 can emit an ATR beam and irradiate the CCD array 7, thereby guiding the center of the CCD array 7 to align with the ATR beam.

[0035] Example 2

[0036] This embodiment provides a total station target point aiming method based on ATR beam guidance.

[0037] The following details the specific operation of the total station target point aiming method based on ATR beam guidance:

[0038] First, this method uses the ATR beam to guide the total station's tilting head, aligning it with the center of the circular prism. This improves the automation of total station monitoring and allows for remote manual correction to enhance the aiming accuracy. The basic principle is based on the ATR beam alignment principle of a CCD array. An ATR beam emitting probe is installed above the total station's CCD array, and the tilting motion of the total station's head is controlled by remotely controlling the ATR beam emitting probe's movement, thus completing the aiming task. The specific approach is as follows:

[0039] A. When the total station needs to find a target monitoring point and there is no monitoring point in the field of view, turn on the ATR beam emission system and the ATR beam mapping light spot will appear on the CCD array;

[0040] B. The rotation of the gimbal of the remote-controlled ATR beam emission system generates relevant commands to the CCD array, which in turn guides the motor to rotate and adjust the telescope's field of view, aligning the ATR beam with the telescope's central axis. This, in turn, causes the center of the crosshairs to move the center of the CCD array, thereby aligning the ATR beam with the center of the CCD array and enabling the telescope's field of view to follow the beam.

[0041] C. When a monitoring point appears in the field of view, fine-tune the ATR beam emission system so that the center of the objective lens gradually moves closer to the monitoring point.

[0042] D. When the objective lens shakes, turn off the ATR beam emission system and aim it at the center of the monitoring point circular prism to complete the remote aiming process.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
