[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings, i.e., embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] The present utility model embodiment proposes a positioning system, which may include a reference station 100, an antenna of the reference station 100 and a positioning base station, wherein the antenna of the reference station 100 may be installed at the reference station 100 to lift the antenna or adjust the angle of the antenna. The positioning base station may be connected to the antenna of the reference station 100 in communication, so that the positioning base station may receive satellite signals to obtain the global position of the antenna of the reference station 100.

[0029] It can be understood that the antenna of the base station 100 can receive satellite signals to obtain its own location information, the positioning base station can send the location information of the antenna of the base station 100 to the target device, the target device can obtain its own location information through the mobile station antenna, and after the target device obtains the location information of the antenna of the base station 100, it performs differential correction with its own location information, thereby helping the autonomous operating equipment to obtain a more accurate real-time location.

[0030] The antenna of the reference station 100 can be electrically connected to the positioning base station. For example, the antenna of the reference station 100 can be electrically connected to the positioning base station through a signal line, and part of the signal line can be set in the reference station 100 to protect the signal line. The positioning base station and the reference station 100 can be designed in combination, and the two can be installed outdoors in an integrated manner, or they can be designed separately, that is, the positioning base station is set indoors, and the antenna of the reference station 100 is installed in the outdoor reference station 100. Such a separate design helps to reduce the weight of the object to be supported by the reference station 100.

[0031] In the related art, the installation process of the base station 100 in the positioning system is relatively complicated. Based on this, the applicant has conducted in-depth research to solve the problem of how to simplify the installation process of the base station 100 while ensuring the structural reliability of the base station 100, so as to form the technical solution of the present application.

[0032] The structure of the technical solution of this application is described in detail below.

[0033] Please refer to Figure 4 In some embodiments, the reference station 100 provided by the utility model includes a plurality of uprights 10, which have positioning holes 11 and are hollow inside to form a threading channel 12, and two adjacent uprights 10 are connected by a connector 20; the inner wall of the upright 10 is sleeved on the outer wall of the connector 20, and the connector 20 has a retractable positioning bead 21, which protrudes from the outer wall of the connector 20, and the positioning bead 21 is adapted to the positioning hole 11 to limit the axial rotation of the upright 10 and the connector 20.

[0034] The reference station 100 provided in this embodiment is mainly used for receiving and transmitting positioning signals. During the installation of the reference station 100, the operator connects the same poles 10 through the connector 20 to achieve height adjustment. The interior of the pole 10 and the connector 20 are both hollow for passing the signal line. The outer wall of the connector 20 is smaller than the inner wall of the pole 10 to allow the two to be sleeved. The connector 20 has a positioning column bead, and the positioning bead 21 can be extended relative to the outer wall of the connector 20. In the original state, the positioning bead 21 is in an extended state and protrudes from the outer wall of the connector 20. The pole 10 has a positioning hole 11 adapted to the positioning bead 21. When the adjacent poles 10 are connected through the connector 20, after the two are sleeved, the positioning bead 21 of the connector 20 protrudes from its outer wall and is at least partially accommodated in the positioning hole 11 of the pole 10, thereby limiting the relative axial rotation of the pole 10 and the connector 20. Such a limiting effect facilitates the subsequent installation of the fixing screws.

[0035] Please refer to Figure 2 In some embodiments, the connector 20 includes connecting tubes 22 extending in a first direction and a second direction respectively and connected to each other, and the first direction is opposite to the second direction.

[0036] The connector 20 may include connecting tubes 22 extending in a first direction and a second direction, respectively, the first direction and the second direction being opposite. One pole 10 is connected to one of the connecting tubes 22, and another pole 10 is connected to another connecting tube 22. The two poles 10 are connected through the connecting tubes 22 in opposite directions of the connector 20, so that the reference station 100 is extended in the height direction.

[0037] Please refer to Figure 2In some embodiments, the connector 20 further includes a connecting tube 22 extending in a third direction and interconnected with the first direction and the second direction, and the third direction is perpendicular to the first direction.

[0038] In this embodiment, the addition of the third direction enables different combinations of the poles 10 and the connectors 20. For example, one pole 10 can be connected to the connecting tube 22 extending in the first direction, and another pole 10 can be connected to the connecting tube 22 extending in the second direction. Multiple poles 10 can be spliced ​​by the connector 20 to adjust the height of the reference station 100. For another example, one pole 10 can be connected to the connecting tube 22 in the first direction or the second direction, and another pole 10 can be connected to the connecting tube 22 extending in the third direction, so as to adjust the angle of the tubes of two adjacent poles 10, so that the angle of the reference station 100 can be adjusted. That is to say, the connector 20 extending in three directions provides the operator with the option of adjusting the height and angle of the reference station 100.

[0039] See also Figure 3 In some embodiments, an elastic member 23 is provided inside the connector 20, and the elastic member 23 is connected to the positioning bead 21. When the vertical pole 10 is connected to the connector 20, the positioning bead 21 prevents the two from rotating relative to each other. The positioning bead 21 connected to the elastic member 23 can shrink when subjected to pressure. During the sleeve connection between the vertical pole 10 and the connector 20, the positioning bead 21 shrinks under the pressure of the inner wall of the vertical pole 10, so that the vertical pole 10 can be smoothly sleeved with the connector 20. When the positioning bead 21 coincides with the positioning hole 11 of the vertical pole 10, the positioning bead 21 loses the pressure of the inner wall of the vertical pole 10 and returns to the original state and is stuck in the positioning hole 11. The positioning bead 21 with elastic characteristics makes the positioning of the vertical pole 10 and the connector 20 more convenient.

[0040] See also Figure 3 In some embodiments, the elastic member 23 has two elastic arms 231 connected to each other, and the two elastic arms 231 are in an acute angle shape.

[0041] The positioning bead 21 is connected to the elastic member 23. Since the elastic member 23 has two elastic arms 231 with sharp angles, the elastic arms 231 can expand or reduce the angle between the two elastic arms 231 under the action of external force, and the position of the positioning bead 21 changes with the size of the angle. Specifically, the elastic member 23 can be a strip plate, and the two elastic arms 231 are formed by bending the strip plate from the middle. The strip plate bent into an acute angle can be accommodated in the inner wall space of the connecting member 20. One end of the strip plate contacts the inner wall of the connecting member 20. The positioning bead 21 can be fixed to the other end of the strip plate by welding or the like. The expansion and contraction amount of the positioning bead 21 is obtained by changing the angle of the elastic arms 231 under pressure.

[0042] In some embodiments, the elastic member 23 may also be a metal wire, which is bent from the middle, one end of which is connected to the inner wall of the connecting member 20, and the other end is connected to the positioning bead 21. The metal wire has good deformation ability and can be easily bent from the middle, and the bent metal wire is easily accommodated in the hollow tube wall.

[0043] See also Figure 3 In some embodiments, the sleeved position of the connector 20 and the vertical pole 10 has a mounting hole 24 for the positioning bead 21. The mounting hole 24 provides a fixed position for the positioning bead 21 and allows the positioning bead 21 to expand and contract relative to the tube wall of the connector 20 within a certain range, effectively limiting the rotation between the vertical pole 10 and the connector 20.

[0044] See also Figure 4 In some embodiments, the connector 20 has a fixing threaded hole 25, the vertical pole 10 has a fixing hole 13 matched with the fixing threaded hole 25, and the connector and the vertical pole 10 are fixedly connected by bolts 26. The connector 20 and the vertical pole 10 are initially fixed by the positioning beads 21. In order to ensure a more stable connection between the connector 20 and the vertical pole 10, the connector 20 and the vertical pole 10 need to be fixedly connected by bolts 26 to prevent the two from coming out after the initial fitting by the positioning beads 21 is completed, and further prevent the two from rotating relative to each other.

[0045] See also Figure 4 In some embodiments, the fixing hole 13 and the positioning hole 11 are located at different heights of the vertical pole 10, and are not arranged in the same direction or opposite directions. This design is intended to solve some defects of the sleeve connection between the pipe walls. Specifically, there is an inevitable gap between the pipe walls, especially for the pipe walls of longer lengths, which are prone to shaking after being sleeved. In order to solve this problem and ensure the stability and reliability of the reference station 100, when the bolt 26 is connected, the fixing hole 13 and the positioning hole 11 are staggered in height and radial angle, which has the following supplementary advantages: First, the staggered design in height expands the connection range of the vertical pole 10 and the connecting member 20, effectively reduces the degree of shaking after the pipe wall is sleeved, and avoids the instability caused by the gap, especially when the reference station 100 is subjected to external vibration or impact, its stability is further guaranteed. Secondly, the staggered setting of the fixing hole 13 and the positioning hole 11 forms a certain angle, which effectively prevents the possibility of relative rotation between the vertical pole 10 and the connecting member 20. This angle design can provide additional constraints to prevent the connected parts from rotating or moving due to external forces or environmental factors.

[0046] Please continue reading Figure 1In some embodiments, the top of the base station 100 has a mounting platform for mounting an antenna. The mounting platform has holes for the signal line to pass through to connect the base station 100 antenna. The antenna mounting platform can be set to be rotatably connected relative to the pole 10. The antenna can flexibly adjust the mounting platform according to the actual environment to obtain the best signal reception effect. In this way, the base station 100 has two angle adjustment mechanisms: one is to adjust the installation angle of the pole 10 through the connecting pipe extending in three directions of the connecting piece 20, and the other is to directly adjust the angle of the antenna through the antenna mounting platform.
