Description

Technical Field

[0001] This invention relates to the field of total station technology, specifically to an automatic target recognition total station that can optimize engineering surveying processes and its usage method. Background Technology

[0002] Automatic target recognition total stations, often referred to as "surveying robots" or "automatic total stations" in engineering surveying, are highly intelligent surveying devices integrating functions such as automatic target recognition, precise aiming, angle and distance measurement, dynamic tracking, and data recording. Existing automatic target recognition total stations include a measurement module for data acquisition and measurement. To protect this module, a protective cover is typically fitted over it. Furthermore, to stabilize the total station and improve measurement accuracy, existing automatic target recognition total stations also have tripods, for example. During use, unfolding the tripod and removing the protective cover of the measurement module must be done sequentially, and after measurement, retracting the tripod and replacing the protective cover must also be done sequentially. This makes the entire measurement process cumbersome, thus affecting measurement efficiency. Therefore, existing automatic target recognition total stations suffer from the problem of inefficient measurement due to cumbersome procedures. To address these issues, this invention proposes an automatic target recognition total station that optimizes the engineering surveying process and its usage method. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic target recognition total station and its usage method that can optimize the engineering survey process, simplify the steps of the survey process, and improve survey efficiency.

[0004] This invention is achieved through the following technical solution: According to one aspect of the present invention, an automatic target identification total station that optimizes engineering surveying processes is provided, comprising: The measurement module integrates an automatic target recognition system, an electro-optical ranging unit, and an angle encoder. The automatic target recognition system is used to acquire and process target images through an image sensor to automatically identify and aim at the measurement point. The electro-optical ranging unit is used to transmit ranging signals to the target and receive reflected signals to calculate the distance. The angle encoder is used to accurately measure the horizontal and vertical angles of the total station. A protective housing having an internal cavity for accommodating the measuring module, the internal cavity having an inlet / outlet formed on one side of the protective housing, the measuring module being vertically retractable at the inlet / outlet; and The total station tripod includes a central shaft, support legs, and connecting rods. The central shaft is slidably connected to the protective housing along the vertical direction. The central shaft is fixed to the measuring module. A plurality of support legs are arranged around the central shaft and rotatably connected to the protective housing. The plurality of support legs are linked to the central shaft through the connecting rods. The total station tripod has a folded form and an unfolded form. When the total station tripod is in the folded form, the measuring module is housed in the inner cavity of the protective housing. When the total station tripod is switched to the unfolded form, the measuring module extends out from the entrance of the protective housing.

[0005] Optionally, the measuring module is provided with a protective cover, which covers the entrance and exit of the protective housing when the total station tripod is in the folded state.

[0006] Optionally, a dustproof structure is provided between the protective housing and the protective cover. The dustproof structure includes a fan, an annular air outlet, and a sloping air guide platform. The annular air outlet is located on the side of the protective cover facing the protective housing. The sloping air guide platform is located on the outside of the protective housing. The annular air outlet is positioned directly opposite the sloping air guide surface of the sloping air guide platform. The air outlet side of the fan is connected to the annular air outlet.

[0007] Optionally, when the protective cover is fitted onto the entrance / exit of the protective housing, a first sealing ring is provided on the contact surface between the two.

[0008] Optionally, the protective housing is provided with a through hole, the central shaft moves vertically through the through hole, and a second sealing ring is provided inside the through hole.

[0009] Optionally, a plurality of radially movable gravity frames are elastically connected to the protective housing located around the second sealing ring via elastic elements. The plurality of gravity frames are magnetically connected to the second sealing ring, and the measuring module is driven to engage with the gravity frames via inclined planes.

[0010] Optionally, the second sealing ring is a hollow tubular structure, the interior of the second sealing ring is filled with magnetic powder, and the gravity frame has magnets that can attract the magnetic powder.

[0011] Optionally, the measuring module is provided with a magnetic shielding plate, and when the measuring module is housed in the protective housing, the magnetic shielding plate is positioned between the gravity frame and the second sealing ring.

[0012] Optionally, the support leg is a telescopic rod.

[0013] According to another aspect of the present invention, a method for using an automatic target identification total station that optimizes engineering surveying processes as described above is provided, comprising the following steps: Step 1: Before measurement, smoothly unfold the total station tripod, ensuring that each support point is firmly in contact with the ground. The measurement module will automatically extend from the entrance and exit of the protective housing as the total station tripod unfolds and enter the ready-to-work state. Step 2: During measurement, use the measurement module to perform engineering measurements and data acquisition. During operation, the total station with automatic target recognition must be kept stable, accurately aligned with the target point, and the measurement data must be recorded in real time to initially verify the effectiveness of the total station with automatic target recognition. Step 3: After measurement, slowly retract the total station tripod. The measuring module will smoothly retract into the inner cavity of the protective housing as the total station tripod retracts. Check that the measuring module has been completely retracted and locked. Finally, clean and store the automatic target recognition total station.

[0014] Compared with existing technologies, this invention provides an automatic target recognition total station and its usage method that can optimize engineering surveying processes, and has the following beneficial effects: 1. The measuring module of the present invention can extend out of the protective housing as the total station tripod is extended, and can also retract into the protective housing as the total station tripod is retracted. This allows the retraction or extension of the total station tripod and the action of putting on or taking off the protective housing on the outside of the measuring module to be completed simultaneously, thereby simplifying the steps of the measurement process and improving measurement efficiency. 2. This invention provides a dustproof structure between the protective housing and the protective cover. When the protective cover is opened, the fan is activated to generate airflow. The airflow is discharged from the annular air outlet and blows towards the inclined air guide surface of the inclined air guide platform. The airflow forms an annular air curtain surrounding the measuring module between the protective housing and the protective cover. The measuring module is surrounded by the air curtain, which can reduce the erosion of the measuring module by dust and water vapor and the intrusion into the inner cavity of the protective housing. 3. This invention utilizes multiple gravity frames positioned around the second sealing ring, magnetically connected to the second sealing ring. The measuring module and the gravity frames are driven by inclined planes. When the measuring module retracts into the inner cavity of the protective housing, the second sealing ring, relying on its own elasticity, tightly clamps itself onto the outer surface of the central shaft, forming a reliable radial seal and ensuring the static sealing performance at the connection between the central shaft and the protective housing. When the measuring module exits from the inner cavity of the protective housing, the gravity frames allow the inner surface of the second sealing ring to disengage from the outer wall of the central shaft, reducing the frictional resistance experienced by the central shaft during movement and preventing the second sealing ring from experiencing accelerated wear due to long-term friction, thus effectively extending its service life.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] As described in the background section, existing automatic target recognition total stations include a measurement module for data acquisition and measurement. To protect the measurement module, a protective cover is usually fitted over it. Additionally, to stably support the total station, existing automatic target recognition total stations also have tripods, such as tripods. When using the total station, unfolding the tripod and removing the protective cover of the measurement module must be done sequentially. After measurement, retracting the tripod and putting the protective cover back on the measurement module must also be done sequentially. This makes the entire measurement process cumbersome, thus affecting measurement efficiency. Therefore, existing automatic target recognition total stations suffer from the problem of cumbersome measurement procedures affecting measurement efficiency.

[0019] To address the above issues, please refer to the following implementation example: Figures 1 to 5According to one aspect of the present invention, an automatic target recognition total station that optimizes engineering surveying processes is provided. It mainly includes a measurement module 100, a protective housing 200, and a total station tripod 300. The measurement module 100 integrates an automatic target recognition system, an electro-optical distance measuring unit, and an angle encoder. The automatic target recognition system is used to acquire and process target images through an image sensor to automatically identify and aim at measurement points. The electro-optical distance measuring unit is used to transmit distance measuring signals to the target and receive reflected signals to calculate the distance. The angle encoder is used to accurately measure the horizontal and vertical angles of the total station. Through the combined operation of the automatic target recognition system, the electro-optical distance measuring unit, and the angle encoder, automated measurement with the total station can be achieved. The protective housing 200 is mainly used to protect the measuring module 100. The protective housing 200 has an inner cavity 201 to accommodate the measuring module 100. An entrance / exit 202 is formed on one side of the inner cavity 201. The measuring module 100 is vertically retractable and located at the entrance / exit 202. The total station tripod 300 mainly serves to stably support the entire total station. The total station tripod 300 specifically includes a central shaft 310, support legs 320, and connecting rods 330. The central shaft 310 is vertically slidably connected to... The protective housing 200, the central shaft 310, and the measuring module 100 are fixed together. Several support legs 320 are arranged around the central shaft 310 and rotatably connected to the protective housing 200. The support legs 320 can be rotatably connected to the protective housing 200 via pivots 340. The support legs 320 and the central shaft 310 are linked together via connecting rods 330. The connecting rods 330 and the support legs 320, as well as the connecting rods 330 and the central shaft 310, can all be connected via pivots 340, thus achieving linkage. The total station tripod 300 has both folded and unfolded configurations. Figure 1 This diagram shows the total station tripod 300 in its unfolded configuration. Figure 2 A schematic diagram is shown of the total station tripod 300 in the folded form. When the total station tripod 300 is in the folded form, the measuring module 100 is housed in the inner cavity 201 of the protective housing 200. When the total station tripod 300 is switched to the unfolded form, the measuring module 100 extends out from the inlet 202 of the protective housing 200.

[0020] The automatic target recognition total station with the above-described structure, which optimizes the engineering surveying process, allows the measuring module 100 to extend from the protective housing 200 as the total station tripod 300 unfolds, and to retract into the protective housing 200 as the total station tripod 300 retracts. This allows the unfolding or retracting of the total station tripod 300 and the application or removal of the protective housing 200 to the measuring module 100 to be completed simultaneously, thereby simplifying the measurement process and improving measurement efficiency.

[0021] like Figures 1 to 4As shown, in some embodiments, the measuring module 100 is provided with a protective cover 210, which covers the entrance 202 of the protective housing 200 when the total station tripod 300 is in a folded state. The protective cover 210 and the protective housing 200 together form a closed storage space in which the measuring module 100 is housed and better protected.

[0022] like Figure 3 As shown, in some embodiments, a dustproof structure 400 is provided between the protective housing 200 and the protective cover 210. The dustproof structure 400 includes a fan 410, an annular air outlet 420, and a sloping air guide platform 430. The annular air outlet 420 is located on the side of the protective cover 210 facing the protective housing 200, and the sloping air guide platform 430 is located on the outer side of the protective housing 200. The annular air outlet 420 is positioned directly opposite the guiding slope 431 of the sloping air guide platform 430. The air outlet side of the fan 410 is connected to the annular air outlet 420. In one embodiment, the protective cover 210 has a hollow structure inside, and the exhaust side of the fan 410 is connected to the annular air outlet 420 through the hollow part of the protective cover. In another embodiment, the exhaust side of the fan 410 can also be connected to the annular air outlet 420 through a pipeline structure. With the above settings, when the protective cover 210 is opened, the fan 410 is started to form an airflow. The airflow is discharged from the annular air outlet 420 and blows towards the guide slope 431 of the inclined air guide platform 430. The airflow forms an annular air curtain 440 surrounding the measuring module 100 between the protective shell 200 and the protective cover 210. The measuring module 100 is surrounded by the air curtain, which can reduce the erosion of the measuring module 100 by dust and water vapor and reduce the intrusion into the inner cavity 201 of the protective shell 200.

[0023] like Figure 4 As shown, in some embodiments, when the protective cover 210 covers the entrance 202 of the protective housing 200, a first sealing ring 220 is provided on the contact surface between the two. The first sealing ring 220 can improve the sealing performance between the protective cover 210 and the protective housing 200, and reduce dust and moisture intruding into the inner cavity 201 of the protective housing 200.

[0024] In some embodiments, the protective housing 200 is provided with a through hole 203, through which the central shaft 310 moves vertically, and a second sealing ring 540 is provided inside the through hole 203. When the protective cover 210 is closed, the second sealing ring 540 can improve the airtightness of the inner cavity 201 of the protective housing 200, reducing the intrusion of moisture and dust.

[0025] like Figures 3 to 5As shown, in some embodiments, multiple gravity frames 500 are radially movable along the central axis 310 and elastically connected to the protective housing 200 surrounding the second sealing ring 540 via elastic elements 510. The gravity frames 500 are magnetically connected to the second sealing ring 540, and the measuring module 100 is driven to engage with the gravity frames 500 via an inclined plane. Specifically, the elastic element 510 can be a compression spring, and the second sealing ring 540 can be an elastic rubber ring. The gravity frames 500 are L-shaped, and the bottom of the protective housing 200 has a sliding groove 204 for mounting the gravity frames 500 and a mounting groove 205 for mounting the first sealing ring 220. The sliding groove 204 and the mounting groove 205 are interconnected, and the gravity frames 500 are elastically connected to the sliding groove 204 via compression springs. The bottom of the measuring module 100 has a pushing inclined plane 530. With the above design, when the measuring module 100 is retracted into the inner cavity 201 of the protective housing 200, the measuring module 100 pushes the gravity frame 500 through the inclined plane, causing the gravity frame 500 to overcome the elastic force of the elastic element 510 and move away from the second sealing ring 540. At this time, since the gap between the gravity frame 500 and the second sealing ring 540 exceeds the effective magnetic range, the magnetic attraction between them can be ignored. In this state, the second sealing ring 540 is tightly clamped to the outer surface of the central shaft 310 by its own elastic force, forming a reliable radial seal and ensuring the static sealing performance at the connection between the central shaft 310 and the protective housing 200. When the measuring module 100 exits from the inner cavity 201 of the protective housing 200, the pressure of the measuring module 100 on the gravity frame 500 is released. Under the rebound force of the elastic element 510, the gravity frame 500 moves towards the second sealing ring 540, shortening the distance between itself and the second sealing ring 540. Once it enters the effective range of magnetic force, a magnetic attraction is generated between the gravity frame 500 and the second sealing ring 540. This attraction acts on the outer periphery of the second sealing ring 540, overcoming its own elasticity and causing it to expand radially, slightly increasing its inner diameter. At this time, the inner surface of the second sealing ring 540 disengages from the outer wall of the central shaft 310, thereby reducing the frictional resistance experienced by the central shaft 310 during movement and preventing the second sealing ring from experiencing accelerated wear due to long-term friction, effectively extending its service life.

[0026] As shown in Figure 5, in some embodiments, the second sealing ring 540 is a hollow tubular structure, and the interior of the second sealing ring 540 is filled with magnetic powder 541. The attraction frame 500 has magnets 520 that can attract the magnetic powder 541. This arrangement can cause uniform deformation in all circumferential parts of the second sealing ring 540, thus extending the service life of the second sealing ring 540.

[0027] like Figure 3 and Figure 4As shown, in some embodiments, the measuring module 100 is provided with a magnetic shielding plate 550. When the measuring module 100 is housed within the protective housing 200, the magnetic shielding plate 550 is positioned precisely between the gravity frame 500 and the second sealing ring 540. When the measuring module 100 is housed within the inner cavity 201 of the protective housing 200, the magnetic shielding plate 550 can further reduce the magnetic attraction between the gravity frame 500 and the second sealing ring 540, allowing the second sealing ring 540 to be more firmly secured to the outside of the central shaft 310, thereby improving the dustproof and waterproof performance of the protective housing 200.

[0028] like Figure 1 and Figure 2 As shown, in some embodiments, the support foot 320 is a telescopic rod. By setting the support foot 320 as a telescopic rod, the length of the support foot 320 is adjustable, thereby allowing the height of the total station to be adjusted as needed during use. When not in use, the support foot 320 can also be retracted to a shorter state, which reduces the overall volume of the total station during transport and storage.

[0029] like Figure 3 and Figure 4 As shown, in some embodiments, to reduce the radial wobble of the central shaft 310 when it moves vertically relative to the protective housing 200, a guide sleeve 600 is fixed to the bottom of the protective housing 200. The central shaft 310 slides through the guide sleeve 600, and through the guiding engagement with the guide sleeve 600, the central shaft 310 can move more stably relative to the protective housing 200 vertically. Furthermore, to facilitate fixing the total station tripod 300 in its unfolded form, a limit screw 610 is provided on the guide sleeve 600. When the limit screw 610 is loosened, the central shaft 310 can move vertically relative to the protective housing 200; when the limit screw 610 is tightened, the central shaft 310 cannot move vertically relative to the protective housing 200.

[0030] According to another aspect of the present invention, a method for using an automatic target identification total station that optimizes engineering surveying processes as described above is provided, comprising the following steps: Step 1: Before measurement, smoothly unfold the total station tripod 300, ensuring that each support point is firmly in contact with the ground. The measurement module 100 will automatically extend from the inlet 202 of the protective housing 200 as the total station tripod 300 unfolds and enter the ready-to-work state. Step 2: During measurement, use the measurement module 100 to perform engineering measurement and data acquisition. During the operation, the total station with automatic target recognition must be kept stable, accurately aligned with the target point, and the measurement data must be recorded in real time to preliminarily verify the effectiveness of the total station with automatic target recognition. Step 3: After measurement, slowly retract the total station tripod 300. The measuring module 100 will smoothly retract into the inner cavity 201 of the protective housing 200 as the total station tripod 300 retracts. Check whether the measuring module 100 has been completely retracted and locked. Finally, clean and store the automatic target recognition total station.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
