Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping devices, and in particular to a surveying and mapping engineering auxiliary surveying and mapping device and method thereof. Background Art

[0002] Existing engineering surveying and mapping devices mainly include GPS equipment, total stations, laser measuring instruments, etc. When conducting surveying and mapping, these devices are generally directly installed on a support structure supported by a tripod.

[0003] When conducting surveying and mapping, in order to ensure the accuracy of the measurement data and the stability of the installation of the surveying and mapping device, the mounting bracket of the surveying and mapping device is fixed. The fastening of the surveying and mapping device is relatively cumbersome. If the equipment is frequently moved over long distances, the bracket fixing structure of the surveying and mapping device must be disassembled back and forth, which is very time-consuming.

[0004] There are also relatively convenient installation brackets available, such as magnetic brackets, which can complete the installation of the surveying and mapping device by directly magnetically attaching the surveying and mapping device to the supporting plate on the upper side of the bracket.

[0005] However, since the surveying and mapping devices are generally used outdoors in a poor environment, if there are foreign objects such as dust and impurities on the magnetic structure of the bracket or the magnetic matching structure of the surveying and mapping device, it will affect the magnetic installation effect, reduce the stability of the surveying and mapping device during adjustment and measurement, and have an adverse effect on the measurement of the surveying and mapping device.

[0006] This means that surveying and mapping personnel need to inspect and clean the magnetic structure of the mounting bracket and the magnetic matching structure of the surveying and mapping device every time they install the surveying and mapping device, which increases the number of operational steps during field measurement and affects the efficiency of field surveying and mapping.

[0007] In summary, how to make the installation of surveying and mapping equipment more convenient while not increasing the use and operation of surveying and mapping personnel during field measurement, ensuring the stability of the surveying and mapping equipment during use, and improving measurement efficiency have become problems that need to be solved. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides a surveying and mapping engineering auxiliary surveying and mapping device and method thereof, which makes the installation of the surveying and mapping device more convenient, while ensuring the stability of the surveying and mapping device during use, and will not increase the cumbersome operations of surveying and mapping personnel during field measurement too much, thereby improving the measurement efficiency.

[0009] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0018] As a preferred technical solution of the device of the present invention: the insulating plastic sleeve is provided with a third through hole, and the upper opening of the third through hole and the metal protrusion can be set to an inverted truncated cone shape, so that the two can be quickly matched.

The support plate is also provided with a conductor lower through hole connected with the sunken circular groove, and the lower end of the metal rod core passes through the conductor lower through hole.

[0020] As a preferred technical solution of the device of the present invention: the vertical groove depth dimension of the second installation groove is smaller than the thickness dimension of the magnetic suction cup.

[0023] The present invention provides a method for using a surveying and mapping engineering auxiliary surveying and mapping device, comprising the following contents:

[0024] S1. Fix the support box with the assembled conductor assembly, positioning plate, and disk assembly on the upper side of the bracket structure, and then directly clamp the bottom of the measuring instrument on the upper side of the support box.

[0025] S2. The elastic travel switch is directly pressed down on the bottom side of the measuring instrument. The electric control box receives the downward pressure signal and determines that the measuring instrument has been clamped on the upper side of the support box.

[0026] S3. The magnetic metal cap at the bottom of the measuring instrument is magnetically connected to the magnetic suction cup embedded on the upper surface of the positioning plate.

[0027] S4. When there is no foreign matter on the surface of all magnetic suction cups and magnetic metal caps, the two metal protrusions of the magnetic metal caps are inserted downward into the insulating plastic sleeve and contact the top side of the metal rod core. The transverse conductor bars, longitudinal conductor bars and extension conductors of the conductor parts are connected in series to form a loop. The electrical control box detects the loop current signal and determines that the magnetic suction of the measuring instrument is installed normally. The LED indicator light shows green.

[0028] S5. When there is foreign matter on the surface of any magnetic suction cup or magnetic metal cap, the metal protrusion of the magnetic metal cap cannot contact the top side of the metal rod core downward, and the transverse conductor bars, longitudinal conductor bars and extension conductors of the conductor cannot be connected in series to form a loop. The electrical control box does not detect the loop current signal, but the electrical control box receives the downward pressure signal of the elastic travel switch, and determines that the magnetic suction installation of the measuring instrument is abnormal. The LED prompt light is displayed in red and the buzzer sounds a prompt.

[0029] S6. The surveying and mapping personnel dismantle the measuring instrument, clean the magnetic suction cup and the magnetic metal cap, and install the measuring instrument again after the surface of the magnetic suction cup and the magnetic metal cap are clean. The LED indicator light will turn green.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The present invention completes the rapid installation of the measuring instrument by magnetic attraction, and the bottom of the measuring instrument directly presses down the elastic travel switch during installation to automatically determine whether the measuring instrument has been installed. The operation is simple and quick, and no complicated fastening operation is required. Compared with the traditional installation method, it saves time and energy, and is particularly suitable for measurement scenarios where equipment is frequently migrated.

[0032] 2. The device of the present invention can automatically detect whether the magnetic installation of the measuring instrument is normal. When there is no foreign matter on the surface of the magnetic suction cup, and the magnetic metal cap and the metal rod core are in normal contact to form a loop, the LED prompt light will display green; if there is a foreign matter causing poor contact and unable to form a loop, the LED prompt light will display red and the buzzer will sound a prompt, assisting surveying and mapping personnel to promptly discover abnormalities in the magnetic connection area, avoid unstable magnetic installation of the measuring instrument due to foreign matter between the magnetic connection structure, and avoid affecting the measurement results due to abnormal magnetic installation.

[0033] 3. The convenient installation method designed by the present invention reduces the time for installation and disassembly of the surveying and mapping device. At the same time, the intelligent detection function avoids the surveying and mapping personnel from repeatedly checking and cleaning the magnetic connection structure, which shortens the measurement operation cycle as a whole, improves the efficiency of the measurement work, and enables the surveying and mapping personnel to complete more measurement tasks in a shorter time.

When there is a foreign object on the surface of any magnetic suction cup (401) or magnetic metal cap (501), the metal protrusion (5011) of the magnetic metal cap (501) cannot contact the top side of the metal rod core (405) downward, the transverse conductor (2022), the longitudinal conductor (2023), and the extension conductor (2024) of the conductor member (202) cannot be connected in series to form a loop, and the electric control box (105) does not detect the loop current signal, but the electric control box (105) receives the downward pressure signal of the elastic travel switch (106), and it is determined that the magnetic suction installation of the measuring instrument (5) is abnormal, the LED prompt light (107) is displayed in red, and the buzzer (108) emits a prompt sound; S6. The surveying and mapping personnel dismantle the measuring instrument (5), clean the magnetic suction cup (401) and the magnetic metal cap (501), and after the surfaces of the magnetic suction cup (401) and the magnetic metal cap (501) are clean, reinstall the measuring instrument (5), and the LED indicator light (107) turns green.
