[0002] As one of the core tools in the field of modern measurement, the total station can not only achieve high-precision measurement of angles and distances, but also has the functions of data processing and storage, which greatly improves the efficiency and reliability of measurement work.

[0003] However, since the measurement principle of the total station is based on straight-line measurement using laser ranging technology, when there are obstacles between the instrument installation location and the measurement target point, the laser signal will be blocked, resulting in the inability to effectively reach the target point. The measurement process will be affected, making it impossible to carry out effective measurement work normally.

[0004] When encountering obstacles during measurement, the traditional solution is to reposition the instrument to avoid the impact of the obstacle. However, when there are many obstacles, frequently repositioning the instrument not only wastes a lot of time, but also introduces measurement errors due to frequent repositioning, making it impossible to guarantee the accuracy of the measurement results.

DETAILED DESCRIPTION

[0032] The following describes embodiments of the present application in more detail with reference to the accompanying drawings. Although the accompanying drawings illustrate embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0033] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0035] Unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0036] Since the measurement principle of the total station 6 is a straight line measurement based on laser ranging technology, when there is an obstacle 8 between the instrument installation position and the measurement target point, the laser signal will be blocked, resulting in the inability to effectively reach the target point, the measurement process will be affected, and effective measurement work cannot be carried out normally.

[0037] When encountering obstacles 8 during measurement, the traditional solution is to change the instrument position to avoid the influence of obstacles 8. However, when there are many obstacles 8, frequently changing the instrument position not only wastes a lot of time, but also introduces measurement errors due to frequent re-setting of the station, making it impossible to guarantee the accuracy of the measurement results.

[0038] In response to the above problems, an embodiment of the present application provides a relay prism observation device that can ensure the normal progress of measurement work and the accuracy of measurement results.

[0039] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0044] Figure 5 It is a schematic diagram of the structure of the laser rangefinder 3 using calculation in an embodiment of the present application.

[0045] See also Figure 1-5 A relay prism observation device is used to cooperate with a total station 6 for detection and measurement. The relay prism observation device includes: a fixed plate 1, a goniometer 2, a laser rangefinder 3, a first prism 4 and a second prism 5.

[0046] A first through hole 101 is provided at the middle of the fixing plate 1 , and positioning baffles 103 are provided on the left and right sides of the first through hole 101 .

[0047] A positioning rod 102 is provided in the middle of the bottom of the fixing plate 1 .

[0048] In this embodiment, by providing the positioning rod 102 , the fixing plate 1 can be quickly installed through the positioning rod 102 to facilitate measurement work.

[0049] The goniometer 2 is an electronic goniometer. A mounting housing 201 is fixedly connected to the goniometer's movable axis. The reading axis of the goniometer 2 is fixedly mounted on the fixed plate 1, located to the side of the first through-hole 101. This allows the mounting housing 201 to pass through the first through-hole 101 and to be positioned centrally within the positioning baffle 103. The goniometer 2 includes a built-in Bluetooth module, enabling Bluetooth transmission of measured data.

[0050] Specifically, a reading fixing plate 202 is provided on the reading axis of the goniometer 2 . Two mounting through holes are provided on the reading fixing plate 202 . Bolts pass through the mounting through holes to fix the reading axis of the goniometer 2 .

[0051] In this embodiment, after the goniometer 2 is fixedly installed, the reading axis of the goniometer 2 is fixed, and the movable axis of the goniometer 2 can rotate around the reading axis, and the rotation angle can be measured through the reading axis.

[0052] The laser rangefinder 3 is installed in the installation housing 201 , and the internal dimensions of the installation housing 201 are set according to the dimensions of the laser rangefinder 3 .

[0053] In this embodiment, after the laser rangefinder 3 is installed in the installation housing 201, the laser rangefinder 3 is in a horizontal state, and the laser rangefinder 3 can only perform pitch and rotation movements, which is convenient for the operator to adjust and measure.

[0054] Specifically, a foam pad 203 is installed on the inner wall of the installation shell 201 .

[0055] In this embodiment, by providing and installing the foam pad 203 , the laser rangefinder 3 can be better clamped and protected.

[0056] Specifically, three positioning threaded holes 104 are sequentially provided on the diagonal line of the positioning baffle 103 from high to low, and bolts are passed through the positioning threaded holes 104 to fix the housing 201 .

[0057] In this embodiment, after the angle of the mounting housing 201 is adjusted, the positioning threaded holes 104 of different heights can be selected and the mounting housing 201 can be tightened and fixed with bolts to fix the angle of the laser rangefinder 3 in the mounting housing 201.

[0058] The first prism 4 and the second prism 5 are symmetrically mounted on the left and right sides of the first through hole 101. The center height of the first prism 4 and the second prism 5 after installation is the same as the center height of the laser rangefinder 3 when it is placed horizontally in the installation housing 201.

[0059] In this embodiment, the first prism 4 and the second prism 5 are dedicated surveying prisms, which are mounted on the fixed plate 1 by bolts. When a total station 6 is used for measurement and an obstacle 8 is encountered, the relay prism observation device is set up behind a position where both the total station 6 and the target prism 7 to be observed can be seen simultaneously. The setting direction of the relay prism observation device is then adjusted, and the pitch angle of the housing 201 is set up so that the laser rangefinder 3 is aligned with the center of the target prism 7 to be observed, and the total station 6 can simultaneously observe both prisms on the relay prism observation device. After the relay prism observation device is set up, the distance between the target prism 7 to be observed and the relay prism observation device can be measured using the laser rangefinder 3, and the deflection angle of the laser rangefinder 3 at this time can be measured using the goniometer 2.

[0060] like Figure 4As shown, in this embodiment, the first prism 4 and the second prism 5 on the relay prism observation device are observed by the total station 6, and the position coordinates of the first prism 4 and the second prism 5 relative to the total station 6 can be measured. The plane position composed of the first prism 4 and the second prism 5 can be determined in the total station 6 device through these two point position coordinates. Because the first prism 4 and the second prism 5 are symmetrically arranged on both sides of the center of the first through hole 101, the position coordinates of the laser rangefinder 3 relative to the total station 6 can be determined through these two point position coordinates.

[0061] like Figure 5 As shown, since the laser rangefinder 3 can only perform pitch motion, the deflection angle of the laser rangefinder 3 is measured by the goniometer 2 to determine the coordinate azimuth between the relay prism observation device and the target to be measured. At the same time, the distance between the target prism 7 and the relay prism observation device is measured by the laser rangefinder 3. Therefore, the position coordinates of the target prism 7 relative to the relay prism observation device can be calculated. The position coordinates of the target prism 7 relative to the total station 6 can be calculated through coordinate calculation to complete the position measurement of the target prism 7. During the measurement process, there is no need to frequently move the total station 6, effectively avoiding the introduction of measurement errors caused by frequent re-stationing, and effectively ensuring the accuracy of the measurement results.

[0062] Specifically: the relay prism observation device of this embodiment further includes: a tripod;

[0063] The tripod is provided with a mounting base.

[0064] In this embodiment, by configuring a tripod and a mounting base, a stable and flexible measurement platform can be provided for the relay prism observation device, making it convenient for operators to perform measurement work.

[0065] The technical solutions in the embodiments of the present application include the following beneficial effects:

[0066] The embodiment of the present application sets a first prism 4 and a second prism 5, so as to measure the position coordinates of the first prism 4 and the second prism 5 relative to the total station 6. At the same time, the distance between the target prism 7 to be observed and the relay prism observation device is measured by the laser rangefinder 3, and the deflection angle of the laser rangefinder 3 at this time is measured by the goniometer 2. The position coordinates of the target prism 7 to be observed relative to the relay prism observation device can be calculated, and the position coordinates of the target prism 7 to be observed relative to the total station 6 can be calculated by coordinate positive calculation to complete the position measurement of the target prism 7 to be observed, effectively avoiding the introduction of measurement errors due to frequent re-stationing, and effectively ensuring the accuracy of the measurement results.

[0067] The relay prism observation device of the embodiment of the present application is simple and low-cost to manufacture, simple and convenient to operate, and has high on-site construction efficiency. It can improve the efficiency of on-site measurement work, save time and personnel costs, ensure the normal progress of measurement work, and ensure the accuracy of measurement results.
