Description

[0001] This application is a divisional application of the following application, the original application's application date: January 27, 2022, the original application's application number: 202210100211.7, and the original application's invention title: A total station simulation teaching device. Technical Field

[0002] This invention relates to the field of distance and angle measurement technology, and specifically to a total station simulation device for teaching purposes. Background Technology

[0003] A total station is a high-tech surveying instrument integrating optics, mechanics, and electronics. It is a surveying instrument system that integrates the functions of measuring horizontal angles, vertical angles, distances (slope distances and horizontal distances), and elevation differences. Because it can complete all the measurement work at a station with a single instrument setup, it is called a total station. It is currently widely used in precision engineering surveying or deformation monitoring fields such as the construction of large above-ground buildings and underground tunnels.

[0004] Currently, many universities offer total station courses in related majors. However, the practical teaching of total stations generally suffers from several problems: (1) Surveying work requires multiple people to work together, and due to limitations in collaboration conditions and safety, it is difficult to conduct individual practical training; (2) Most surveying courses use the campus of the student's school for internships, but engineering projects are diverse and widely distributed, making it impossible for students to conduct actual measurements at real construction sites during practical teaching; (3) Due to course duration and weather limitations, it is difficult to conduct real-time training; (4) Total stations are high-precision instruments, which are expensive and easily damaged, making it impossible to provide one for each student for practical training; (5) Traditional surveying practice teaching is generally conducted in a centralized manner, with one teacher teaching multiple students during internships, making it impossible to ensure the training effect for each student. In general, the traditional teaching model and methods of total stations are monotonous and outdated, and are out of step with the rapidly developing digital age.

[0005] In response, Chinese utility model patent CN206339231U discloses a surveying instrument simulation model device, including a total station simulation model device, a mobile phone mounting device, an operation panel simulation device, a sensor signal acquisition device, and a server (i.e., a PC training terminal). The total station simulation model device includes a total station simulation model and an angle sensor. The total station simulation model includes the total station body, telescope, handle, vertical brake knob, base, and horizontal brake knob. The mobile phone mounting device is embedded in the telescope, and the mobile phone (i.e., the precision aiming screen) is installed in front of the telescope's objective lens, forming a precision aiming module. During use, rotating the knob allows the angle sensor to measure angle changes. The sensor signal acquisition device collects the signals and transmits them to the PC training terminal. The program background processes the operation signals by performing perspective conversion and measurement data processing, and transmits the viewpoint scene data from the virtual total station's eyepiece to the mobile phone screen in the total station simulation model.

[0006] The aforementioned surveying instrument simulation model device combines virtual simulation technology with engineering surveying teaching. Through the cooperation of angle sensors, sensor signal acquisition devices, and PC training terminals, the actual adjustment effect brought about by rotating the knob is ultimately displayed on the mobile phone screen, simulating the adjustment effect screen that a person would see after rotating the knob when actually operating a total station. This allows for indoor simulation teaching and solves the aforementioned series of technical problems.

[0007] However, the aforementioned surveying instrument simulation model can only train students in the use of the fine aiming view module. In actual teaching with a total station, before performing fine aiming, a coarse aiming operation is required. This involves using the coarse aiming device on the physical total station to align with the target and roughly determine the aiming direction. During this process, since the total station is set up outdoors, the operator can observe the distant real-world scene. However, in simulation teaching, the simulation model is placed in the laboratory and is not moved to the field. Furthermore, there is no physical target being measured; the images are transmitted from the PC training terminal to the mobile phone screen. Therefore, coarse aiming training is no longer possible.

[0008] However, if coarse aiming training is omitted as a result, students' comprehensive mastery of the total station will be compromised, failing to achieve the full teaching objective. In other words, the existing surveying instrument simulation model device is not fully functional and cannot realize richer and more comprehensive teaching functions, thus affecting students' comprehensive mastery of the total station. Summary of the Invention

[0009] The purpose of this invention is to provide a total station simulation teaching device that can not only perform fine aiming training but also coarse aiming training, has more powerful teaching functions, and can improve students' comprehensive mastery of the total station.

[0010] To achieve the above objectives, the total station simulation teaching device of this invention adopts the following technical solution:

[0011] A total station simulation teaching device includes a total station body and a fine aiming view module mounted on the total station body. A handle is provided on the top of the total station body, and a fixed bracket for fixing a coarse aiming view screen is installed on the handle. The coarse aiming view screen is used to display a coarse aiming image transmitted from a PC training terminal, simulating what the human eye sees. A rotating structure is provided on the fixed bracket to rotate the coarse aiming view screen relative to the handle, so that the display image on the coarse aiming view screen faces forward or backward, in order to cooperate with the left and right operation of the total station body and the fine aiming view module.

[0012] The beneficial effects of the above technical solution are as follows: The total station simulation teaching device of the present invention not only includes a fine aiming view module installed on the total station body for fine aiming training, but also has a fixed bracket installed on the handle of the total station body for fixing the coarse aiming view screen. The coarse aiming view screen is used to display the coarse aiming image transmitted by the PC training terminal, simulating what the human eye sees. In this way, the operator can see the overall image of the direction of the measurement target transmitted by the PC training terminal as soon as he looks up. That is, the operator can see the scene that is observed in front of him when operating a real total station outdoors as soon as he looks up, and determine whether the measurement target is in the display screen. This simulates coarse aiming training, making the teaching function more powerful. It makes up for the deficiency that the teaching device cannot allow students to conduct coarse aiming observation because it is set indoors. It gives people the feeling of still conducting measurement training outdoors, which is closer to the real total station teaching process and can improve students' comprehensive mastery of the total station.

[0013] Meanwhile, the fixed bracket is equipped with a rotating structure, which is used to rotate the coarse aiming screen relative to the handle so that the display screen faces forward or backward. In this way, during the left and right operation of the total station body and the fine aiming screen module, the display screen can be rotated to keep the display screen facing the person's face, making it easier for the person to observe the coarse aiming screen and to complete the left and right operation more realistically, achieving the same teaching effect as a real total station.

[0014] Furthermore, the top surface of the handle is flat, and the fixed bracket includes a support plate supported on the top surface of the handle and a fixing structure fixed on the support plate for fixing the coarse aiming screen. The rotating structure includes a connecting shaft connecting the support plate and the handle. The axis of the connecting shaft extends in the vertical direction so that the fixed bracket and the coarse aiming screen can rotate around the axis of the connecting shaft.

[0015] The beneficial effects of the above technical solution are as follows: the handle and the support plate of the fixed bracket are connected by a connecting shaft, and the axis of the connecting shaft extends in the vertical direction, so that the fixed bracket and the coarse viewing screen can rotate around the axis of the connecting shaft. This makes rotation more convenient and the structure simple.

[0016] Furthermore, the connecting shaft is a connecting screw.

[0017] The advantages of the above technical solution are: it is convenient to install and disassemble, and when the connecting screws are tightened, they can provide good fixation for the fixed bracket, ensuring the stability of the coarse viewing screen. When the connecting screws are loosened, the fixed bracket can be rotated, making the operation relatively convenient.

[0018] Furthermore, the connecting screw passes through the handle from bottom to top and is threaded into the support plate.

[0019] The advantages of the above technical solution are that there is generally more operating space below the handle, which facilitates the installation and adjustment of the connecting screws.

[0020] Furthermore, the fixing structure includes a fixed clamp and a movable clamp connected to the fixed clamp via an elastic element. The fixed clamp is fixed to the support plate, and the movable clamp is used to deform the elastic element under force when pulled open and clamp the coarse viewing screen together with the fixed clamp under the reaction force of the elastic element.

[0021] The advantages of the above technical solution are as follows: by using a fixed clamp and a movable clamp connected to the fixed clamp through an elastic element as a fixing structure, the fixing effect of the coarse viewing screen can be guaranteed, and the operation is simple and convenient.

[0022] Furthermore, there are two sets of fixed clamps and movable clamps, spaced apart from each other on the left and right. The two fixed clamps are fixed at both ends of the support plate, and the connection position between the connecting shaft and the support plate is located in the middle of the support plate.

[0023] The advantages of the above technical solution are: the two sets of fixed clamps and movable clamps have a better fixing effect, and the two sets are spaced apart on the left and right, respectively fixed at both ends of the support plate, while the connecting shaft is located in the middle, which makes the fixing effect of the coarse viewing screen more stable, and also facilitates the installation of the connecting shaft and avoids interference.

[0024] Furthermore, the support plate, fixed clamp, and movable clamp are all located directly above the handle so that the center of gravity of the fixed bracket and the coarse aiming screen passes through the vertical axis of the total station body.

[0025] The beneficial effects of the above technical solution are: to avoid the added fixed bracket and coarse aiming screen from affecting the center of gravity of the entire device, thereby preventing the device from rotating when performing horizontal angle measurement and ensuring the accuracy of horizontal angle measurement.

[0026] Furthermore, the total station body is the body of a physical total station, and the handle is a metal handle fixedly connected to the body. The metal handle includes a top arm and side arms connected to both ends of the top arm. The bottom of the side arms is detachably connected to the body by fasteners, and a fixed bracket is installed on the top arm.

[0027] The beneficial effects of the above technical solution are as follows: the total station body is based on the body of a physical total station, which can make full use of the structure of the physical total station itself. By modifying the physical total station, the total station simulation teaching device of this invention can be formed, using locally available materials and saving costs. At the same time, the handle is a metal handle that is fixedly connected to the body, that is, the handle is a remanufactured handle. The handle includes a top arm and a side wall. The bottom of the side arm is detachably connected to the body by fasteners, utilizing the original structure on the body for fixing the handle, which facilitates the fixing of the metal handle. Furthermore, the fixing bracket is installed on the top arm, and the remanufactured handle top arm easily meets the installation requirements of the fixing bracket.

[0028] Furthermore, the fixed bracket includes a fixed base and a screen clamp. The bottom of the fixed base is provided with at least a pair of clamps for being installed on the front and rear sides of the handle. The two clamps are fixedly connected by bolts so that the fixed base is fixed to the handle. The screen clamp is used to hold the coarse viewing screen. The screen clamp is hinged to the fixed base through a hinge shaft extending in the left and right direction so that the screen clamp can be flipped back and forth relative to the fixed base.

[0029] The beneficial effects of the above technical solution are as follows: the fixed bracket includes two parts: a fixed base for fixing to the handle and a screen clamp for clamping the coarse viewing screen to ensure the fixation of the coarse viewing screen. The screen clamp is hinged to the fixed base through a hinge shaft extending in the left and right direction, so that the screen clamp can be flipped back and forth relative to the fixed base. That is, the coarse viewing screen can be flipped back and forth to make the display screen face forward or backward, which is convenient for left and right operation.

[0030] Furthermore, the total station simulation teaching device also includes a support frame for supporting and fixing the total station body.

[0031] The beneficial effects of the above technical solution are as follows: by supporting and fixing the total station body with a support frame, it is more in line with the actual outdoor use effect of the physical total station, and it can train students to set up and operate the total station, which is closer to actual teaching.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0044] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0045] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. Additionally, the terms "above" and "below" are based on the orientation and positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention, not to indicate that the referred device or component must have a specific orientation, and therefore should not be construed as limiting the invention.

[0046] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0047] Example 1 of the total station simulation teaching device in this invention is as follows: Figure 1 As shown, it includes the main body of the device and the support frame 8, combined with Figure 2 , Figure 3 and Figure 4 As shown, the main body of the device includes a total station body 1 and a precision aiming view module 2 mounted on the total station body 1. A support frame 8 is used to support and fix the total station body 1. In this embodiment, the total station body 1 is the body of a physical total station. The entire main body of the device is modified from the original physical total station. The precision aiming view module 2 was remanufactured mainly to realize simulation teaching. The precision aiming view module 2 replaces the coaxial telescope and laser rangefinder module on the original physical total station. Its internal structure and working principle are the same as those in patent document CN206339231U, including components such as the precision aiming view screen, which will not be described in detail in this invention.

[0048] Because it uses the original physical total station body, the angle sensing function of the original machine is retained. The main body of the total station remains basically unchanged, ensuring that the instrument's measurement accuracy is not reduced. Furthermore, information such as the horizontal angle, vertical angle, and electronic bubble can be transmitted to the PC training terminal via the original machine's RS-232 interface. In addition, the operation panels 5 on the front and rear sides of the total station body 1 are also the original operation panels of the physical total station. However, since the precision aiming view module on the original machine has been removed, operation panels 5 no longer have a specific function. Their only remaining purpose is to activate the original machine's angle sensing function by pressing the power button on operation panel 5, facilitating the transmission of the aforementioned information to the PC training terminal.

[0049] To ensure that the total station simulation teaching device still possesses the functions of a physical total station and facilitates teaching and training, such as... Figures 1-4 As shown, mounting brackets 6 are respectively installed on the exterior of the front and rear operation panels 5. Each mounting bracket 6 includes a fixing part that is fixedly connected to the frame outside the operation panel 5, and a clamping part for holding a calibration simulation screen 7. The calibration simulation screen 7 is used to display the operation interface of the simulated original operation panel transmitted by the PC training terminal. The clamping part can rotate relative to the fixing part, and the angle of the clamping part can be changed by the adjustment knob on the mounting bracket 6, thereby facilitating the operation of the lower operation panel 5.

[0050] like Figures 1-4 As shown, a handle 11 is fixedly installed on the top of the total station body 1. The handle 11 is a metal handle, while the original total station's handle and body are both made of plastic. The original handle itself is detachably fixed to the total station body 1 by fixing screws 12. Therefore, this invention actually removes the original handle, re-manufacturing a new handle 11, and still uses fixing screws 12 to fix the handle 11 to the total station body 1. Specifically, as... Figure 5 , Figure 6 and Figure 7 As shown, the handle 11 includes a top arm 111 and side arms 112 connected to both ends of the top arm 111. The bottom of the side arm 112 is detachably and fixedly connected to the total station body 1 by fixing screws 12.

[0051] like Figures 1 to 7 As shown, a first fixed bracket 3 for fixing the coarse aiming view screen 4 is installed on the top arm 111 of the handle 11. The coarse aiming view screen 4 is used to display the coarse aiming image transmitted by the PC training terminal, simulating what the human eye sees. In this way, the operator can see the overall image of the direction of the measurement target transmitted by the PC training terminal as soon as he looks up. That is, the operator can see the scene that is observed in front of him when operating a real total station outdoors as soon as he looks up, and determine whether the measurement target is in the display screen. This simulates coarse aiming training, making the teaching function more powerful. It makes up for the deficiency that the teaching device cannot be used for coarse aiming observation because it is set indoors. It gives people the feeling of still conducting measurement training outdoors, which is closer to the real total station teaching process and can improve the students' comprehensive mastery of the total station.

[0052] Meanwhile, the first fixed bracket 3 is equipped with a rotating structure, which is used to rotate the coarse aiming screen 4 relative to the handle 11 so that the display screen 4 faces forward or backward. In this way, during the left and right operation of the total station body 1 and the fine aiming screen module 2, the rotation of the coarse aiming screen 4 can keep the display screen facing the face, making it easier for personnel to observe the coarse aiming screen and more realistically complete the left and right operation, achieving the same teaching effect as a real total station.

[0053] Specifically, the top and bottom surfaces of the top arm 111 are both flat. The first fixed bracket 3 includes a support plate 31 supported on the top surface of the top arm 111 and a fixing structure fixed on the support plate 31 for fixing the coarse aiming screen 4. The aforementioned rotating structure includes a connecting shaft connecting the support plate 31 and the top arm 111. The axis of the connecting shaft extends in the vertical direction so that the first fixed bracket 3 and the coarse aiming screen 4 can rotate around the axis of the connecting shaft. This makes rotation convenient and the structure simple. Furthermore, the display image of the coarse aiming screen 4 remains correct relative to the operator after rotation and will not be upside down, eliminating the need for the PC training terminal to adjust the orientation of the transmitted image.

[0054] Furthermore, the aforementioned connecting shaft is a connecting screw 34. The connecting screw 34 passes through the top arm 111 of the handle from bottom to top and is threadedly connected to the support plate 31. Therefore, the metal handle remanufactured in this invention is actually to facilitate the machining of screw holes on the handle, facilitating the installation of the connecting screw 34 and the support plate 31, thus ensuring the installation and fixing effect of the first fixed bracket 3. Using the connecting screw 34 as the connecting shaft and installing it from bottom to top facilitates installation and adjustment. Specifically, when the connecting screw 34 is tightened, it can provide a good fixing effect on the first fixed bracket 3, ensuring the stability of the coarse viewing screen 4. When the connecting screw 34 is loosened, the first fixed bracket 3 can be rotated, making the operation relatively convenient.

[0055] Furthermore, the aforementioned fixing structure includes a fixed clamp 32 and a movable clamp 33 connected to the fixed clamp 32 via an elastic element. The fixed clamp 32 is fixed on the support plate 31. The movable clamp 33 is used to deform the elastic element under force when pulled open and clamp the coarse aiming screen 4 together with the fixed clamp 32 under the reaction force of the elastic element. The fixed clamp 32 and the movable clamp 33 are similar to existing mobile phone clamps. The aforementioned mounting bracket 6 is also an existing mobile phone clamp. Therefore, the coarse aiming screen 4, the calibration simulation screen 7, and the fine aiming screen all use electronic devices such as mobile phones that can install operating systems and have displays.

[0056] In this embodiment, two sets of fixed clips 32 and movable clips 33 are provided, spaced apart horizontally. The two fixed clips 32 are respectively fixed to both ends of the support plate 31, and the connecting screw 34 is located in the middle of the support plate 31. The two sets of fixed clips 32 and movable clips 33 provide better fixing effect, and the horizontal spacing between the two sets with the connecting screw 34 in the middle makes the fixing effect of the coarse viewing screen 4 more stable, and also facilitates the installation of the connecting screw 34, avoiding interference.

[0057] Meanwhile, the support plate 31, the fixed clamp 32, and the movable clamp 33 are all located directly above the top arm 111. The support plate 31 is a regular rectangular plate with the same width as the top arm 111. The fixed clamp 32 and the movable clamp 33 are also the same width as the top arm 111. This ensures that the center of gravity of the first fixed bracket 3 and the coarse aiming screen 4 passes through the vertical axis of the total station body 1 (the vertical axis is the geometric axis around which the main instrument rotates, also known as the vertical axis or longitudinal axis. It consists of a main shaft and a bushing, which are tightly fitted and rotate flexibly. During measurement, it should be in a plumb state). This avoids the added first fixed bracket 3 and coarse aiming screen 4 from affecting the center of gravity of the entire device, that is, it avoids the instrument's center of gravity from deviating from the instrument's vertical axis, which would cause the instrument to rotate slightly during precise observation of the horizontal angle (sub-second level), thus affecting the accuracy of the horizontal angle measurement.

[0058] This invention relates to a total station simulation teaching device. To train students in coarse aiming operations similar to those of a physical total station, a coarse aiming screen 4 is added to simulate the view seen by students using the coarse aiming device of a physical total station outdoors. The screen displays the image that replaces the actual coarse aiming observation. Since the main structure of the total station remains largely unchanged and the axis relationships are correct, data is transmitted to a PC training terminal via the original instrument's RS-232 interface. Based on this information, the PC training terminal sends corresponding commands to the coarse aiming screen 4. During left-hand or right-hand operation, the coarse aiming screen 4 remains stationary on one side. Students rotate the fine aiming module 2 by operating the knobs on the original instrument, changing the horizontal or vertical angle. The original instrument's RS-232 interface transmits the angle information to the PC training terminal, which then sends it back to the coarse aiming screen 4, thus controlling the coarse aiming view to change accordingly in the horizontal or vertical direction, achieving synchronization.

[0059] During actual measurements of horizontal angles, vertical angles, and distances, the calibration simulation screen 7 replaces the original total station control panel, enabling the input of relevant information and the control of the virtual instrument in a virtual scenario. Steps that would otherwise require operation on the physical total station control panel are now performed on the calibration simulation screen 7. The calibration simulation screen 7 is connected to a PC training terminal to control and simulate the functions of the original control panel.

[0060] In summary, the total station simulation teaching device of the present invention has more powerful functions, fully possesses the teaching functions of a physical total station, is closer to the actual teaching process, can achieve the expected teaching effect, and improve students' comprehensive mastery of the total station.

[0061] Example 2 of the total station simulation teaching device in this invention is as follows: Figure 8 As shown, unlike Embodiment 1, the coarse viewing screen 4 is mounted on top of the handle 11 via a second fixing bracket 9, as... Figure 9 and Figure 10As shown, the second fixed bracket 9 includes a fixed base 91 and a screen clamp 92. The bottom of the fixed base 91 is provided with two pairs of clamping plates 93 for mounting on the front and rear sides of the handle 11. The two pairs of clamping plates 93 are fixedly connected by bolts 94 to fix the fixed base 91 to the handle 11. The screen clamp 92 is used to hold the coarse viewing screen 4, and the screen clamp 92 is hinged to the fixed base 91 through a hinge shaft 95 extending in the left-right direction, so that the screen clamp 92 can rotate back and forth relative to the fixed base 91.

[0062] The main difference between Example 2 and Example 1 is the different mounting brackets for the coarse viewing screen, which leads to a different rotation method for the coarse viewing screen 4. In Example 1, it rotates left and right, while in Example 2, it flips forward and backward. In addition, the coarse viewing screen 4 in Example 2 is equipped with a gyroscope, which the system can use to identify left and right side operations and switch the view. That is, after the coarse viewing screen 4 is flipped 180 degrees, the image will automatically be inverted, making it easier to observe.

[0063] Example 3 of the total station simulation teaching device in this invention: Unlike Example 2, the handle is the handle of the original physical total station.

[0064] In other embodiments of the total station simulation teaching device: the total station simulation teaching device does not include a support frame, and the main body of the device can be placed on a workbench or table.

[0065] In other embodiments of the total station simulation teaching device: the total station body is not the body of a physical total station, but a remanufactured body. That is, the entire teaching device is not modified from the original physical total station, but a remanufactured teaching device.

[0066] In other embodiments of the total station simulation teaching device: the support plate, fixed clamp, and movable clamp may not be located directly above the handle, but may be offset. Through the fixed position of the coarse aiming screen and the structural design of the fixed support, such as adding counterweights, it can be ensured that the center of gravity of the fixed support and the coarse aiming screen passes through the vertical axis of the total station body.

[0067] In other embodiments of the total station simulation teaching device: only one set of fixed clamp and movable clamp is provided. In this case, the fixed clamp is fixed in the middle of the support plate. In order to facilitate the installation of the connecting shaft, clearance holes can be provided on the fixed clamp.

[0068] In other embodiments of the total station simulation teaching device: the fixed structure is not in the form of a fixed clamp and a movable clamp. Since the fixed bracket and the coarse aiming screen rotate left and right as a whole, the fixed structure can be designed as a fixed frame with an insertion port at the top, and the position of the coarse aiming screen can be fixed by the fixed frame.

[0069] In other embodiments of the total station simulation teaching device: when a connecting screw is used as the connecting shaft, the connecting screw can also pass through the support plate from top to bottom and be threadedly connected to the handle.

[0070] In other embodiments of the total station simulation teaching device: the connecting shaft is not a connecting screw, but a hinge shaft that serves as a hinge.

[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
