Description

Technical Field

[0001] This utility model belongs to the field of radio direction finding technology, and specifically relates to a radar direction finding device based on a wide-area slope. Background Technology

[0002] In the field of slope monitoring, MIMO slope radar is widely used due to its high-efficiency monitoring capabilities. During operation, it requires the acquisition of coordinates from the two endpoints of the device to accurately determine the radar's installation location and orientation. This coordinate acquisition and orientation calculation step is a crucial prerequisite for the subsequent conversion of radar monitoring data into geographic coordinates, directly affecting the reliability of the slope monitoring results.

[0003] However, existing MIMO slope radars generally have a relatively short structural feature. This feature means that even a small measurement error when acquiring the coordinates of the two endpoints of the radar will be significantly amplified in the subsequent orientation calculation process, resulting in a large deviation in the radar orientation calculation results.

[0004] Significant deviations can directly cause the radar monitoring data to shift when converted to geographic coordinates, making it impossible for the monitoring data to accurately reflect the actual situation of the slope. This seriously affects the accuracy and effectiveness of slope monitoring and makes it difficult to meet the stringent requirements for data accuracy in slope safety monitoring. Utility Model Content

[0005] This invention provides a radar orientation device based on a wide-area slope, addressing the technical problem of poor orientation accuracy in wide-area slope monitoring using existing MIMO-type slope radars. By rotating and scanning the scale on the image scanner dial, and observing that the rotation degrees scanned by both scanners are increasing, it can be determined that the angle detection device is rotating clockwise, and the degree of clockwise rotation is specified. Conversely, by simultaneously rotating the two scanners counterclockwise, and observing that the rotation degrees scanned by both scanners are decreasing, it can be determined that the angle detection device is rotating counterclockwise, and the degree of counterclockwise rotation is specified. This improves the orientation accuracy of the angle detection device in monitoring.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A radar orientation device based on a wide-area slope includes:

[0008] Support rod;

[0009] The dial is fixedly mounted on the support rod and has graduations.

[0010] An angle detection device is equipped with an image scanner, which is used to scan the scale on the dial. The image scanner is located outside the angle detection device. A rotary joint is connected to the angle detection device by screws. The rotary joint is inserted into the support rod and can rotate on its own.

[0011] The rotating joint is rotated relative to the support rod by a rotation angle detection device, and the image scanner rotates and scans the scale on the dial.

[0012] Optionally, the angle detection device has a housing and a cover plate;

[0013] The housing contains two image processors, which are symmetrically arranged about the axis of the housing. The image processors are connected to the image scanner via a first wire and are used to receive images from the image scanner.

[0014] The cover is detachably attached to the housing, and a display is installed on the cover. The display can show data from the image processor, and the display is connected to the image processor via a second wire.

[0015] Optionally, the housing contains a data comparator for comparing data from two image processors. The data comparator is connected to the image processors via a third wire.

[0016] Optionally, a radar antenna is provided on the outside of the housing. The radar antenna is used to transmit data from the data comparator. The radar antenna is connected to the data comparator via a fourth wire.

[0017] Optionally, the end of the data comparator furthest from the fourth wire is provided with a shock-proof pad to prevent the data comparator from being impacted.

[0018] Optionally, the anti-collision pad on the data comparator is positioned directly opposite the push rod, which is located inside the sleeve and can move axially along the axis of the sleeve.

[0019] Optionally, the sleeve is fixedly installed inside the housing, and the sleeve is equipped with an insert that passes through the outside of the sleeve and enters the inside of the sleeve.

[0020] Optionally, the plug is inserted into the push rod, with one end of the push rod contacting the anti-collision pad and the other end of the push rod abutting against the spring.

[0021] Optionally, a positioning post is fixed inside the housing, and a spring is sleeved on the positioning post. The positioning post is used to prevent the spring 12 from moving in the lateral direction of the positioning post.

[0022] Optionally, the push rod has a rod body, an abutment, and a retaining ring;

[0023] The outer peripheral wall of the rod is provided with multiple retaining rings arranged in an array along the longitudinal direction of the rod, and there is a gap between two adjacent retaining rings, into which the positioning pin is inserted.

[0024] One end of the push rod has an abutment, which contacts the anti-collision pad.

[0025] The beneficial effects of this utility model are:

[0026] 1. This utility model uses a rotation angle detection device to rotate the rotary joint relative to the support rod, while the image scanner rotates and scans the scale on the dial. Since both image scanners rotate clockwise simultaneously, and the degree of rotation scanned by the two image scanners is increasing, it can be determined that the angle detection device is rotating clockwise, and the degree of rotation of the angle detection device in the clockwise direction is also known. Conversely, since both image scanners rotate counterclockwise simultaneously, and the degree of rotation scanned by the two image scanners is decreasing, it can be determined that the angle detection device is rotating counterclockwise, and the degree of rotation of the angle detection device in the counterclockwise direction is also known. This improves the orientation accuracy of the angle detection device in monitoring.

After the plug-in passes through the outside of the sleeve and enters the inside of the sleeve, the plug-in is inserted into the gap between two adjacent retaining rings. The plug-in can position the push rod in the up and down movement. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] Example 1;

[0040] like Figures 1-3As shown, this embodiment provides a radar orientation device based on a wide-area slope, including: a support rod 1, a scale 2, and an angle detection device 3; the scale 2 is fixedly mounted on the support rod 1 and has a scale; an image scanner 5 is fixedly mounted on the angle detection device 3, the image scanner 5 is used to scan the scale on the scale 2, the image scanner 5 is located outside the angle detection device 3, and a rotary joint 14 is connected to the angle detection device 3 by screws, the rotary joint 14 is rotatably inserted into the support rod 1;

[0041] The rotation angle detection device 3 causes the rotary joint 14 to rotate relative to the support rod 1, and the image scanner 5 rotates and scans the scale on the dial 2.

[0042] The scale 2 can be set with scale values, such as 0°-360°. That is, each scale on the scale 2 is marked with a degree value. By rotating the image scanner 5, the image scanner 5 can scan the degree value of each scale on the scale 2.

[0043] After the image scanner 5 reads the degree value of each scale on the dial 2, it transmits the data to the image processor 6, which then identifies the degree value of each scale on the dial 2.

[0044] Specifically, such as Figures 1-2 As shown, the angle detection device 3 has a housing 31 and a cover plate 32;

[0045] like Figures 3-4 As shown, an image processor 6 is provided inside the housing 31. There are two image processors 6, which are symmetrically arranged about the axis of the housing 31. The image processors 6 are connected to the image scanner 5 through a first wire 51. The image processors 6 are used to receive images from the image scanner 5.

[0046] Each of the two image scanners 5 reads the degree of each scale on the dial 2, and each of the two image processors 6 receives the data transmitted by its corresponding image scanner 5.

[0047] The cover plate 32 is detachably connected to the housing 31. The cover plate 32 is equipped with a display 4, which can display data from the image processor 6. The display 4 is connected to the image processor 6 via a second wire 61, that is, the display 4 can display the data transmitted by the two image processors 6 respectively.

[0048] The housing 31 is equipped with a data comparator 8, which is used to compare the data of the two image processors 6. The data comparator 8 is connected to the image processor 6 via a third wire 62.

[0049] The outer side of the housing 31 is provided with a radar antenna 7, which is used to transmit data from the data comparator 8. The radar antenna 7 is connected to the data comparator 8 via a fourth wire 71.

[0050] The working principle of this embodiment is as follows: Figure 4 As shown, the angle detection device 3 can rotate clockwise or counterclockwise, allowing the two image scanners 5 to rotate clockwise or counterclockwise. Since the two image scanners 5 rotate simultaneously, the angles they rotate are the same. Therefore, if the two image scanners 5 rotate clockwise simultaneously, the image scanner 5 scans the degree of each scale mark on the dial 2, and the two image scanners 5 can simultaneously read the degree of rotation they have each rotated. Because the two image scanners 5 rotate clockwise simultaneously, the two image scanners 5 can scan the same degree of rotation and the degree of rotation they have each scanned is increasing. Similarly, if the two image scanners 5 rotate counterclockwise simultaneously, the image scanner 5 scans the degree of each scale mark on the dial 2, and the two image scanners 5 can simultaneously read the degree of rotation they have each scanned. Because the two image scanners 5 rotate counterclockwise simultaneously, the two image scanners 5 can scan the same degree of rotation and the degree of rotation they have each scanned is decreasing.

[0051] If both image scanners 5 rotate clockwise simultaneously, then each of the two image processors 6 simultaneously obtains and determines the degree of rotation scanned by the two image scanners 5 and whether the degree of rotation is increasing; if both image scanners 5 rotate counterclockwise simultaneously, then each of the two image processors 6 simultaneously obtains and determines the degree of rotation scanned by the two image scanners 5 and whether the degree of rotation is decreasing; each of the two image processors 6 transmits the obtained data to the data comparator 8.

[0052] The data comparator 8 connects to the two image processors 6. Specifically, if both image scanners 5 rotate clockwise simultaneously, the data comparator 8 compares whether the rotation degrees of each image processor 6 are the same (assuming no malfunction), and whether the rotation degree of each image processor 6 is increasing (clockwise rotation increases the degree). If both image scanners 5 rotate counterclockwise simultaneously, the data comparator 8 compares whether the rotation degrees of each image processor 6 are the same (assuming no malfunction), and whether the rotation degree of each image processor 6 is decreasing (counterclockwise rotation decreases the degree). The data comparator 8 transmits the comparison results to the backend platform (not shown in the figure) via the radar antenna 7.

[0053] Therefore, in this embodiment, based on the simultaneous clockwise rotation of the two image scanners 5 and the increasing rotation degrees obtained from the scanned images by the two image scanners 5, it can be determined that the angle detection device 3 is rotating clockwise, and the degree of clockwise rotation of the angle detection device 3 is also known. Similarly, when the two image scanners 5 simultaneously rotate counterclockwise, and the decreasing rotation degrees obtained from the scanned images by the two image scanners 5 are observed, it can be determined that the angle detection device 3 is rotating counterclockwise, and the degree of counterclockwise rotation of the angle detection device 3 is also known. This improves the orientation accuracy of the angle detection device 3 in monitoring.

[0054] Example 2;

[0055] Based on Example 1, such as Figures 3-4 As shown, the lower end of the data comparator 8, which is away from the fourth wire 71, is provided with an anti-collision pad 81. The anti-collision pad 81 is used to prevent the data comparator 8 from being hit. When the push rod 10 pushes the data comparator 8, the anti-collision pad 81 can protect the data comparator 8 from being hit by the push rod 10.

[0056] like Figure 4 As shown, the anti-collision pad 81 on the data comparator 8 is directly opposite the push rod 10. The push rod 10 is set inside the sleeve 9 and can move axially along the axis of the sleeve 9. The function of the push rod 10 is to hold the anti-collision pad 81 in place to prevent the data comparator 8 from falling off and to avoid affecting the transmission of the radar antenna 7. The data comparator 8 can be stably set on the top inner wall of the housing 31. If the data comparator 8 is damaged, the push rod 10 can be moved down to replace the data comparator 8.

[0057] The sleeve 9 is fixedly installed inside the housing 31. The sleeve 9 is provided with a plug 11, which passes through the outside of the sleeve 9 and enters the inside of the sleeve 9.

[0058] The plug 11 is inserted into the push rod 10. The upper end of the push rod 10 is in contact with the anti-collision pad 81, and the lower end of the push rod 10 abuts against the spring 12.

[0059] A positioning post 13 is fixed inside the housing 31, and a spring 12 is sleeved on the positioning post 13. The positioning post 13 is used to prevent the spring 12 from moving in the lateral direction of the positioning post 13.

[0060] like Figure 5 As shown, the push rod 10 has a rod body 101, an abutment 102, and a retaining ring 103;

[0061] The outer peripheral wall of the rod 101 is provided with a plurality of retaining rings 103 arranged in an array along the longitudinal direction of the rod 101, and there is a gap 104 between two adjacent retaining rings 103, and the positioning post 13 is inserted into the gap 104.

[0062] The upper end of the push rod 10 has an abutment 102, which contacts the anti-collision pad 81. After the plug 11 passes through the outside of the sleeve 9 and enters the inside of the sleeve 9, the plug 11 is inserted into the gap 104 between two adjacent retaining rings 103. The plug 11 can position the push rod 10 in the up and down movement position.

[0063] The working principle of the push rod 10 is as follows: before the insert 11 enters the gap 104, the extension of the spring 12 pushes the push rod 10 upward, and the abutment 102 at the upper end of the push rod 10 contacts the anti-collision pad 81. Then, the insert 11 passes through the sleeve 9 from the outside and enters the inside of the sleeve 9 and the gap 104. The insert 11 can position the push rod 10. The function of the push rod 10 is to hold the anti-collision pad 81.

[0064] If the data comparator 8 is damaged and needs to be replaced, the plug 11 is removed from the inside of the sleeve 9, the push rod 10 moves down, the spring 12 is compressed, and the plug 11 passes through the outside of the sleeve 9 and enters the inside of the sleeve 9 and the gap 104. The plug 11 then positions the push rod 10 to replace the data comparator 8.

[0065] When the push rod 10 moves upward or downward, the plug 11 will be subjected to the axial force of the push rod 10. The plug 11 is provided on both the upper and lower sides of the sleeve 9, and the two plugs 11 can share the axial force of the push rod 10.

As for the software algorithms in the image scanner 5, image processor 6, and data comparator 8, they are not within the scope of protection of this invention. This invention only shows the product structure to facilitate the use of the product. As for the software algorithms, they are programs in the structural hardware.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model.
