Description

Technical Field

[0001] The present application relates to the field of power monitoring technology, and in particular to an overhead line monitoring device and system. Background Art

[0002] Overhead lines are lines that use insulators to secure electrical and / or communication lines to towers erected on the ground to transmit power and / or communication signals. These lines offer numerous advantages, including low cost, easy construction and maintenance, excellent heat dissipation, and ease of expansion and modification. They are widely used in communications, as well as in power transmission and distribution at various voltage levels. Overhead lines are typically exposed to the elements for extended periods, making them severely affected by weather factors and susceptible to external damage. These damage can occur due to vehicle collisions with towers, theft of tower materials, foreign objects (such as kites and balloons) hanging on the lines, ice buildup, and line sway. These can all lead to line failures, ultimately impacting power supply and / or communications. In related technologies, monitoring equipment is installed on towers to monitor the lines through video surveillance and issue warnings when potential line failures are detected, thereby preventing them from occurring. However, existing monitoring equipment typically has limited monitoring angles and locations, and its coverage is limited, making it difficult to achieve optimal monitoring results.

DETAILED DESCRIPTION

[0028] In the related art, monitoring equipment is installed on the towers of overhead lines. The monitoring equipment can monitor the lines by filming and issue an early warning when it detects an event that may cause a line failure, thereby preventing the line from failing. However, the monitoring equipment has a single monitoring angle and location, and its monitoring range is not comprehensive, making it impossible to achieve a good monitoring effect. Moreover, in cold weather, ice (or frost) easily forms on the lens of the monitoring equipment, which ultimately affects the monitoring equipment's ability to film the line and is not conducive to the continuity of line monitoring. In view of this, the present application proposes an overhead line monitoring device and system in the following embodiments to address the above-mentioned drawbacks existing in the related art.

[0029] In order to make the purpose, technical solutions and advantages of the present application more obvious and easy to understand, the present application will be clearly and completely described below in conjunction with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. It should be understood that the embodiments of the present application described below are only used to explain the present application and are not used to limit the present application, that is, based on the various embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0030] See also Figure 1 and Figure 2 , Figure 1It is a structural diagram of the overhead line monitoring device. Figure 2 This is a cross-sectional view of the assembled main control box, monitoring box, and camera module. This embodiment provides an overhead line monitoring device, which is applied to an overhead line. The overhead line includes multiple towers spaced apart and erected on the ground. Multiple lines are connected between any two adjacent towers. These lines can be wires for transmitting electrical energy, communication lines for transmitting communication signals, or even a mixture of wires and communication lines. The specific configuration can be based on actual needs, and this application does not impose a sole limitation on this. Specifically, the overhead line monitoring device includes a base 1, a support 2, a main control box 3, a monitoring box 4, a central controller 31, a displacement mechanism 5, an image processor 41, a camera module 6, a first motor 32 and a second motor 42. The base 1 is used to be arranged on the top of the tower, the displacement mechanism 5 is arranged on the base 1, the support 2 is arranged on the displacement mechanism 5 and is driven and connected to the displacement mechanism 5, the main control box 3 is arranged on the support 2, the central controller 31 and the first motor 32 are both arranged in the main control box 3, the monitoring box 4 is located above the main control box 3, and the first output shaft of the first motor 32 is connected from the main control box 3 to the monitoring box 4. The top of the control box 3 passes through and is connected to the monitoring box 4. The image processor 41 and the second motor 42 are both arranged in the monitoring box 4. The camera module 6 is located on one side of the monitoring box 4. The second output shaft of the second motor 42 passes through the side of the monitoring box 4 and is connected to the camera module 6. The shooting direction of the camera module 6 is perpendicular to the center line of the second output shaft. The camera module 6 is communicatively connected to the image processor 41. The image processor 41, the first motor 32, the second motor 42 and the displacement mechanism 5 are respectively communicatively connected to the central controller 31, and the central controller 31 is used to communicate with the cloud server.

[0031] In this embodiment, the camera module 6 is used to capture the line and / or pole in real time and obtain a corresponding primary monitoring image; the image processor 41 is used to determine whether the line and / or pole is abnormal based on the primary monitoring image and obtain a corresponding judgment result; and the central controller 31 is used to transmit the primary monitoring image and the judgment result to the cloud server. In other words, the camera module 6 can capture the primary monitoring image of the line and / or pole in real time and send the captured primary monitoring image to the image processor 41. The image processor 41 can process the primary monitoring image to determine whether the line and / or pole is abnormal. The image processor 41 can then send the primary monitoring image and the corresponding judgment result to the central controller 31, which then feeds it back to the cloud server. The cloud server is actually a remote monitoring platform. The monitoring personnel are located on the cloud server side. Therefore, the monitoring personnel can easily achieve remote monitoring of the line and / or pole through data exchange between the central controller 31 and the cloud server. In addition, it should be noted that the image processor 41 of this embodiment is equipped with an image recognition algorithm based on artificial intelligence, which can automatically identify abnormal conditions of the line and / or tower based on the main monitoring image, such as regional intrusion, foreign objects hanging on the line, line breakage, line icing, line dancing, external force damage, fire, etc., and feed the identified results back to the cloud server through the central controller 31 so that the monitoring personnel can respond in time; for example, the image processor 41 can perform distance monitoring on the line between two towers based on the main monitoring image, thereby realizing line monitoring and real-time monitoring of whether the line is disconnected. It should also be noted that the main monitoring image obtained by the camera module 6 when shooting the tower includes not only the tower itself, but also the various devices installed on the tower. Therefore, when monitoring the tower in this embodiment, it is not only the tower itself that is monitored, but also the various devices installed on the tower.

[0032] In this embodiment, the central controller 31 plays a master control role, which is used to control the operation of the displacement mechanism 5, the first motor 32 and the second motor 42. Of course, it is not limited to the displacement mechanism 5, the first motor 32 and the second motor 42. The central controller 31 also controls the operation of the third motor 515, the fourth motor 525, the fifth motor 43, the lifting mechanism 7 and the de-icing mechanism 8 described below; the displacement mechanism 5 is used to drive the support 2 to move in the horizontal direction and / or vertical direction, and to make the main control box 3, the monitoring box 4 and the camera module 6 move synchronously; the first motor 32 is used to drive the monitoring box 4 and the camera module 6 to rotate synchronously in the horizontal direction; the second motor 42 is used to drive the camera module 6 to rotate in the vertical direction. That is to say, the central controller 31 can control the displacement mechanism 5 to drive the support 2 to move in the horizontal direction and / or vertical direction. Since the support 2, the main control box 3, the monitoring box 4 and the camera module 6 are connected in sequence, when the support 2 moves in the horizontal direction and / or vertical direction, the main control box 3, the monitoring box 4 and the camera module 6 will naturally move synchronously, so that the point at which the camera module 6 monitors the line and / or the tower can be adjusted; the central controller 31 can also control the second motor 42 to drive the camera module 6 to rotate in the vertical direction, and control the first motor 32 to drive the monitoring box 4 to rotate in the horizontal direction. Since the camera module 6 and the monitoring box 4 are connected, when the monitoring box 4 rotates in the horizontal direction, the camera module 6 will naturally rotate synchronously, so that the angle at which the camera module 6 monitors the line and / or the tower, and the position on the line and / or the tower monitored by the camera module 6 can be adjusted.

[0033] It should be noted that the central controller 31 can adopt any controller commonly used in this field, such as a small computer, a microcontroller such as a single-chip microcomputer, an industrial control computer (IPC), a programmable logic controller (PLC) and a distributed control system (DCS), etc. The specific selection can be based on actual needs, and this application does not make a sole limitation on this. Preferably, the central controller 31 adopts a programmable logic controller. In this case, a basic monitoring process can be set for the overhead line monitoring device through programming. The basic monitoring process includes the control instructions of the central controller 31 to the displacement mechanism 5, the first motor 32, the second motor 42, the third motor 515, the fourth motor 525, the fifth motor 43, the lifting mechanism 7 and the de-icing mechanism 8 (taking the control instruction of the second motor 42 as an example, the control instruction is used to guide the second motor 42 to drive the camera module 6 to rotate a certain angle in the vertical direction), and also includes the timing of the central controller 31 controlling the displacement mechanism 5, the first motor 32, the second motor 42, the third motor 515, the fourth motor 525, the fifth motor 43, the lifting mechanism 7 and the de-icing mechanism 8 (for example, first controlling the camera module 6 to face the tower to monitor the tower, and then controlling the camera module 6 to face the line to monitor the line). Then, in the actual monitoring process, the overhead line monitoring device only needs to cyclically execute this basic monitoring process. As for the specific basic monitoring process, it can be designed according to actual needs, and this application does not make a sole limitation on this.

[0034] As can be seen from the above, this embodiment can not only realize the movement of the camera module 6 in space (i.e., movement in the horizontal and / or vertical directions) so as to adjust the points at which the camera module 6 monitors the lines and / or towers, but also realize the rotation of the camera module 6 360° in the horizontal direction and 360° in the vertical direction so as to adjust the angle at which the camera module 6 monitors the lines and / or towers, and the position on the lines and / or towers monitored by the camera module 6, so that the camera module 6 has a wider monitoring range for the lines and / or towers, thereby realizing all-weather, all-round, multi-angle, and multi-point real-time monitoring of the lines and / or towers, thereby improving the monitoring effect of the lines and / or towers.

[0035] In some embodiments, please combine Figure 3 and Figure 4 , Figure 3 This is the assembly diagram of the support and displacement, lifting and de-icing mechanisms. Figure 4It is a cross-sectional view of an overhead line monitoring device. The base 1 includes a bottom plate 11 and a side plate 12. The side plate 12 is erected on the bottom plate 11 and close to the edge of the bottom plate 11. The length direction of the bottom plate 11 and the side plate 12 are consistent. The bottom plate 11 is used to be set on the top of the tower; the displacement mechanism 5 includes a horizontal displacement mechanism 51 and a vertical displacement mechanism 52, which are respectively connected to the central controller 31 for communication. The horizontal displacement mechanism 51 is set on the side plate 12, and the vertical displacement mechanism 52 is set on the horizontal displacement mechanism 51 and is connected to the horizontal displacement mechanism 51 by driving. The support 2 is set on the vertical displacement mechanism 52 and is connected to the vertical displacement mechanism 52 by driving. Specifically, the horizontal displacement mechanism 51 is used to drive the vertical displacement mechanism 52 to move in the horizontal direction, and to make the support 2, the main control box 3, the monitoring box 4 and the camera module 6 move synchronously; the vertical displacement mechanism 52 is used to drive the support 2 to move in the vertical direction, and to make the main control box 3, the monitoring box 4 and the camera module 6 move synchronously. That is to say, the horizontal displacement mechanism 51 can drive the vertical displacement mechanism 52 to move in the horizontal direction, and since the vertical displacement mechanism 52, the support 2, the main control box 3, the monitoring box 4 and the camera module 6 are connected in sequence, when the vertical displacement mechanism 52 moves in the horizontal direction, the support 2, the main control box 3, the monitoring box 4 and the camera module 6 will naturally move synchronously; the vertical displacement mechanism 52 can drive the support 2 to move in the vertical direction, and since the support 2, the main control box 3, the monitoring box 4 and the camera module 6 are connected in sequence, when the support 2 moves in the vertical direction, the main control box 3, the monitoring box 4 and the camera module 6 will naturally move synchronously.

[0036] As one or more embodiments thereof, the horizontal displacement mechanism 51 includes a connecting plate 511, a gear 512, a rack 513, two slide rails 514 and a third motor 515 communicatively connected to the central controller 31. The two slide rails 514 are arranged on the side plate 12 at intervals along the length direction of the side plate 12. The rack 513 is arranged on the side plate 12 along the length direction of the side plate 12 and is located between the two slide rails 514. The connecting plate 511 is arranged on the two slide rails 514 and slides with the two slide rails 514. The third motor 515 is arranged on the side wall of the connecting plate 511. The gear 512 is arranged on the third output shaft of the third motor 515 and engages with the rack 513. The vertical displacement mechanism 52 is arranged on the side of the connecting plate 511 away from the slide rail 514.

[0037] It can be understood that when it is necessary to move the camera module 6 in the horizontal direction, the central controller 31 can control the third motor 515 to start, and the third motor 515 can drive the gear 512 to rotate through the third output shaft. Since the gear 512 is engaged with the rack 513 arranged along the length direction of the side panel 12, when the gear 512 rotates, it will drive the third motor 515 and the connecting plate 511 to move along the length direction of the side panel 12, that is, the connecting plate 511 will slide along the length direction of the side panel 12 on the two slide rails 514, and since the connecting plate 511, the vertical displacement mechanism 52, the support 2, the main control box 3, the monitoring box 4 and the camera module 6 are connected in sequence, when the connecting plate 511 slides along the length direction of the side panel 12, the vertical displacement mechanism 52, the support 2, the main control box 3, the monitoring box 4 and the camera module 6 will naturally move synchronously, thereby realizing the horizontal movement of the camera module 6.

[0038] As one or more embodiments thereof, the vertical displacement mechanism 52 includes a lead screw 521, a screw block 522, a vertical plate 523, two partitions 524 and a fourth motor 525 communicatively connected to the central controller 31. The vertical plate 523 is arranged on the horizontal displacement mechanism 51, and the two partitions 524 are respectively arranged on the opposite ends of the vertical plate 523. The opposite ends of the lead screw 521 are respectively arranged on the two partitions 524 and respectively rotate with the two partitions 524. The fourth motor 525 is arranged on the side of any partition 524 away from the lead screw 521. The fourth output shaft of the fourth motor 525 is connected to the lead screw 521. The screw block 522 is sleeved on the lead screw 521 and is threadedly connected (or screwed) to the lead screw 521. The support 2 is arranged on the screw block 522.

[0039] It can be understood that when it is necessary to move the camera module 6 in the vertical direction, the central controller 31 can control the fourth motor 525 to start, and the fourth motor 525 can drive the screw 521 to rotate through the fourth output shaft. Since the screw block 522 is sleeved on the screw 521 and is threadedly connected to the screw 521, when the screw 521 rotates, the screw block 522 will slide on the screw 521. Since the screw block 522, the support 2, the main control box 3, the monitoring box 4 and the camera module 6 are connected in sequence, when the screw block 522 slides along the axis of the screw 521, the support 2, the main control box 3, the monitoring box 4 and the camera module 6 will naturally move synchronously, thereby realizing the movement of the camera module 6 in the vertical direction.

[0040] In some embodiments, please combine Figure 5 and Figure 6 , Figure 5 This is a cross-sectional view of the lifting and de-icing mechanism after assembly. Figure 6The figure is a schematic diagram of the assembly of the main control box, monitoring box, and camera module. The support 2 includes a mounting plate 21 and a support plate 22. The mounting plate 21 is vertically mounted on the support plate 22 and close to the edge of the support plate 22. The mounting plate 21 is mounted on the displacement mechanism 5. In addition to the structure described above, the overhead line monitoring device also includes a lifting mechanism 7 and a de-icing mechanism 8. The lifting mechanism 7 and the main control box 3 are adjacently mounted on the support plate 22, with the lifting mechanism 7 close to the mounting plate 21 and the main control box 3 away from the mounting plate 21. The de-icing mechanism 8 is mounted on the lifting mechanism 7 and is drive-connected to the lifting mechanism 7. The lifting mechanism 7 and the de-icing mechanism 8 are respectively communicatively connected to the central controller 31. Preferably, the lifting mechanism 7 includes an electric telescopic rod 71, which is communicatively connected to the central controller 31. The electric telescopic rod 71 is mounted on the surface of the bottom of the support plate 22. The telescopic end of the electric telescopic rod 71 passes through the support plate 22 and is connected to the de-icing mechanism 8. Therefore, the telescopic movement of the electric telescopic rod 71 is the lifting movement of the de-icing mechanism 8.

[0041] Specifically, the lifting mechanism 7 is used to drive the de-icing mechanism 8 to rise when the camera module 6 is located above the de-icing mechanism 8, thereby accommodating the camera module 6 in the de-icing mechanism 8; the de-icing mechanism 8 is used to heat the camera module 6 located inside itself, thereby removing frost on the camera module 6. It is understandable that when the overhead line monitoring device works in a cold environment, ice (or frost) is easily formed on the lens of the camera module 6, which will eventually affect the camera module 6's shooting of the line and / or the tower, and is not conducive to the continuity of monitoring the line and / or the tower; in view of this, the present application is provided with a lifting mechanism 7 and a de-icing mechanism 8. When it is necessary to remove the frost on the camera module 6, the central controller 31 can control the first motor 32 to drive the monitoring box 4 and the camera module 6 to rotate in the horizontal direction, and / or control the second motor 42 to drive the camera module 6 to rotate in the vertical direction to place the camera module 6 directly above the de-icing mechanism 8, and then the lifting mechanism 7 can drive the de-icing mechanism 8 to rise, thereby accommodating the camera module 6 in the de-icing mechanism 8. The de-icing mechanism 8 will then heat the camera module 6 located inside itself, ultimately achieving the purpose of melting the frost on the camera module 6, thereby ensuring the continuity of monitoring of the line and / or pole tower, and facilitating the realization of all-weather monitoring of the line and / or pole tower. Of course, after the frost on the camera module 6 is melted, the lifting mechanism 7 can drive the de-icing mechanism 8 to descend, so that the camera module 6 is separated from the de-icing mechanism 8, so that the camera module 6 can continue to shoot the line and / or pole tower.

[0042] In one or more embodiments, the de-icing mechanism 8 includes a heating box 81, an air duct 82, and an electric heating network 83 and a fan 84, each of which is communicatively connected to the central controller 31. The heating box 81 has a receiving groove 811 that is recessed inward from the side of the heating box away from the support plate 22. The size of the receiving groove 811 is adapted to accommodate the camera module 6. One end of the air duct 82 is inserted into one end of the heating box 81 and communicates with the receiving groove 811. The electric heating network 83 and the fan 84 are spaced apart within the air duct 82, with the electric heating network 83 being close to the receiving groove 811 and the fan 84 being away from the receiving groove 811. Specifically, the electric heating network 83 is used to heat the surrounding air; the fan 84 is used to blow hot air through the electric heating network 83 toward the camera module 6 located in the receiving groove 811, thereby melting frost on the camera module 6 and preventing the operation of the camera module 6 from being affected.

[0043] That is to say, when it is necessary to remove the frost on the camera module 6, the central controller 31 can first control the first motor 32 to drive the monitoring box 4 and the camera module 6 to rotate in the horizontal direction, and / or control the second motor 42 to drive the camera module 6 to rotate in the vertical direction, so as to place the camera module 6 directly above the receiving slot 811, and then control the lifting mechanism 7 to drive the receiving slot 811 to rise, so as to accommodate the camera module 6 inside the receiving slot 811, and then control the electric heating network 83 to generate heat to heat the surrounding air through the electric heating network 83, and finally control the fan 84 to start, and the fan 84 will blow air to the camera module 6 in the receiving slot 811 through the air duct 82. Since the electric heating network 83 is arranged between the receiving slot 811 and the fan 84, the fan 84 will carry the hot air around the electric heating network 83 when blowing air to the camera module 6. In this way, the wind blown by the fan 84 to the camera module 6 is hot air, so as to melt the frost on the camera module 6. Preferably, a drainage hole 812 connected to the receiving groove 811 is provided on the other end of the heating box 81 opposite to the air duct 82, and the position of the drainage hole 812 is lower than the air duct 82; in the process of the fan 84 blowing hot air to the camera module 6, the frost on the camera module 6 will melt into water and drip into the receiving groove 811, and the water in the receiving groove 811 will be discharged to the outside through the drainage hole 812, thereby avoiding water accumulation in the receiving groove 811 and freezing in cold weather, thereby ensuring the normal operation of the de-icing mechanism 8.

[0044] In some embodiments, see Figure 1 as well as Figure 4In addition to the structure given above, the overhead line monitoring device also includes a photovoltaic module 9. The photovoltaic module 9 is arranged on the base 1. The photovoltaic module 9 is electrically connected to the central controller 31, the displacement mechanism 5, the image processor 41, the camera module 6, the first motor 32 and the second motor 42. Specifically, the photovoltaic module 9 is used to convert the solar energy it receives into electrical energy, and use the converted electrical energy to power the central controller 31, the displacement mechanism 5, the image processor 41, the camera module 6, the first motor 32 and the second motor 42. It can be understood that the central controller 31, the displacement mechanism 5, the image processor 41, the camera module 6, the first motor 32 and the second motor 42 are all electrical devices, and their operation requires the supply of electrical energy. Therefore, the present application provides a photovoltaic module 9 to provide them with the electrical energy required for their operation to ensure the normal operation of the overhead line monitoring device.

[0045] In one or more embodiments, the photovoltaic module 9 includes a bracket 91, a solar controller 93, a power supply 94, and a solar panel 92. The bracket 91 is mounted on the base 1, and the solar controller 93, power supply 94, and solar panel 92 are all mounted on the bracket 91. The solar panel 92 is electrically connected to the solar controller 93, which is electrically connected to the power supply 94. The power supply 94 is electrically connected to the central controller 31, the displacement mechanism 5, the image processor 41, the camera module 6, the first motor 32, the second motor 42, etc. Preferably, the bracket 91 is a tripod, the solar panel 92 is mounted on the inclined surface of the tripod, and the solar controller 93 and power supply 94 are both mounted within the tripod.

[0046] Specifically, the solar panel 92 is used to convert the solar energy it receives into electrical energy and transmit the electrical energy to the solar controller 93; the solar controller 93 is used to charge the power supply 94 using the electrical energy converted by the solar panel 92; and the power supply 94 is used to power the central controller 31, the displacement mechanism 5, the image processor 41, the camera module 6, the first motor 32, the second motor 42, etc. It will be understood that the power supply for the various electrical components in the overhead line monitoring device in this application is passive, that is, it does not require an electrical connection to the external power supply 94 via cables, eliminating the need for wiring and facilitating flexible installation.

[0047] It should be noted that the power supply 94 is not limited to supplying power to the central controller 31, the displacement mechanism 5, the image processor 41, the camera module 6, the first motor 32, and the second motor 42. The power supply 94 actually supplies power to all electrical components of the overhead line monitoring device, such as the third motor 515, the fourth motor 525, the fifth motor 43, the lifting mechanism 7, the electric heating network 83, and the fan 84. It should also be noted that there is not limited to one solar panel 92. In order to improve the charging effect of the power supply 94, two or more solar panels 92 can be set on the bracket 91. Preferably, the power supply 94 uses a single battery or a battery pack composed of multiple batteries, such as lead-acid batteries, lithium-ion batteries, and nickel-metal hydride batteries. The specific configuration can be based on actual needs, and this application does not make a sole limitation on this.

[0048] In some embodiments, see Figure 2 In addition to the structure described above, the overhead line monitoring device also includes a fifth motor 43 communicatively connected to the central controller 31 and a pan-tilt camera 10 communicatively connected to the image processor 41. The fifth motor 43 is disposed within the monitoring box 4, and the pan-tilt camera 10 is located on the other side of the monitoring box 4 opposite the camera module 6. The fifth output shaft of the fifth motor 43 extends from the side of the monitoring box 4 and is connected to the pan-tilt camera 10. Specifically, the pan-tilt camera 10 is used to capture auxiliary monitoring images of the line and / or tower in real time; based on this, the image processor 41 is specifically used to determine whether the line and / or tower are abnormal based on the primary monitoring image and the auxiliary monitoring image and obtain a corresponding judgment result. The central controller 31 is specifically used to transmit the primary monitoring image, the auxiliary monitoring image, and the judgment result to the cloud server. In other words, when identifying whether there are abnormalities in the lines and / or towers, not only the camera module 6 is required, but also the pan-tilt camera 10. Specifically, the image processor 41 needs to combine the primary monitoring image captured in real time by the camera module 6 with the auxiliary monitoring image captured in real time by the pan-tilt camera 10 to determine whether there are abnormalities in the lines and / or towers. The judgment result and the relevant images are then fed back to the central controller 31. For example, the pan-tilt camera 10 has a 16-megapixel high-resolution camera and an 8-megapixel CMOS sensor. The high-resolution camera can capture clear and detailed images during the day, while the CMOS sensor can enable monitoring in low-light environments. In addition, the pan-tilt camera 10 is equipped with a thermal imaging function, with a resolution of 256×192 and a focal length of 9mm. Even in darkness (or fog), it can capture temperature information of the lines and / or towers, facilitating multi-faceted monitoring of the lines and / or towers, thereby achieving comprehensive monitoring of the lines and / or towers and ensuring the safe operation of overhead lines.

[0049] In some embodiments, see Figure 2In addition to the structure given above, the overhead line monitoring device also includes a GPS positioning module 44 that is arranged in the monitoring box 4 and is communicatively connected to the central controller 31. Specifically, the GPS positioning module 44 is used to obtain the current location information of the overhead line monitoring device in real time; the central controller 31 is also used to transmit the location information to the cloud server. In other words, the GPS positioning module 44 can obtain the current location information of the overhead line monitoring device in real time, and send the obtained location information to the central controller 31, which is then fed back to the cloud server by the central controller 31, so that the monitoring personnel on the cloud server side can clearly understand the current location of the overhead line monitoring device. Then, when the line and / or tower monitored by the overhead line monitoring device has an abnormality, the monitoring personnel can quickly locate the overhead line monitoring device based on the location information, so that the monitoring personnel can rush to the scene in time for disposal.

[0050] In some embodiments, see Figure 2 and Figure 6 In addition to the aforementioned structure, the overhead line monitoring device also includes a temperature and humidity detector 45 and a wind speed detector 46, which are mounted on top of the monitoring box 4 and communicatively connected to the central controller 31. The wind speed detector 46 is mounted above the temperature and humidity detector 45. Specifically, the temperature and humidity detector 45 is used to detect the surrounding temperature and humidity in real time; the wind speed detector 46 is used to detect the surrounding wind speed in real time. The central controller 31 is also used to transmit the temperature, humidity, and wind speed information to the cloud server. That is to say, the temperature and humidity detector 45 can detect the temperature and humidity information (i.e., temperature information and humidity information) near the overhead line monitoring device in real time, and the wind detector 46 can detect the wind information (such as wind speed, wind direction, etc.) near the overhead line monitoring device in real time. The temperature and humidity detector 45 and the wind detector 46 will send the information they detect to the central controller 31, and then the central controller 31 will feed back the information it receives to the cloud server. In this way, the monitoring personnel on the cloud server side can clearly understand the temperature, humidity, wind speed, wind direction and other information near the overhead line monitoring device, so as to comprehensively evaluate the operating status of the overhead line.

[0051] In some embodiments, see Figure 6The camera module 6 includes a wide-angle camera 62, a blacklight HD camera 63, and a hollow housing 61. One side of the housing 61 is mounted on the second output shaft of the second motor 42. The wide-angle camera 62 and the blacklight HD camera 63 are both located within the housing 61 and are communicatively connected to the image processor 41. The lenses of the wide-angle camera 62 and the blacklight HD camera 63 extend from one end of the housing 61 to be exposed to the outside, facilitating their use in photographing power lines and / or poles. For example, the wide-angle camera 62 has a 2-megapixel resolution and supports picture-in-picture imaging. The blacklight HD camera 63 has an 8-megapixel resolution and utilizes a large aperture lens and a high-sensitivity sensor. It supports full-color night vision capture with a minimum illumination of 0.0001 Lux, enabling high-definition night photography of power lines and / or poles. In addition, those skilled in the art should understand that the monitoring box 4 is not limited to being configured with a wide-angle camera 62, a blacklight-level high-definition camera 63 and a pan-tilt camera 10. In fact, different online monitoring equipment and systems on the market can be flexibly selected. The ultimate goal is to achieve comprehensive and accurate monitoring of the lines and / or towers.

The plurality of overhead line monitoring devices are respectively arranged on the tops of a plurality of pole towers, and the central controller 31 in each overhead line monitoring device is communicatively connected to the cloud server. It can be understood that an overhead line monitoring device is provided on each pole tower, and all overhead line monitoring devices exchange data with the cloud server, which is convenient for the unified management of each section of the overhead line, and also convenient for timely identification of the accident location and arrangement of emergency repairs when a fault occurs in a section of the overhead line.

[0053] The above embodiments are only preferred implementations of the present application, and are not the only limitations on the overhead line monitoring device and related systems; in this regard, those skilled in the art can flexibly set them according to the actual application scenarios based on the above embodiments. It can be understood that through the implementation of the above embodiments of the present application, the overhead line monitoring device is composed of the base 1, the support 2, the main control box 3, the monitoring box 4, the central controller 31, the displacement mechanism 5, the image processor 41, the camera module 6, the first motor 32 and the second motor 42. The base 1 is arranged on the pole tower, the displacement mechanism 5 is arranged on the base 1, the support 2 is arranged on the displacement mechanism 5 and is driven and connected to the displacement mechanism 5, the main control box 3 is arranged on the support 2, the central controller 31 and the first motor 32 are both arranged in the main control box 3, and the monitoring box 4 is located in the main control box. Above the box 3, the first output shaft of the first motor 32 passes through the top of the main control box 3 and is connected to the monitoring box 4, the image processor 41 and the second motor 42 are both arranged in the monitoring box 4, and the camera module 6 is located on one side of the monitoring box 4.

The camera module 6 is communicatively connected to the image processor 41, and the image processor 41, the first motor 32, the second motor 42 and the displacement mechanism 5 are respectively communicatively connected to the central controller 31, and the central controller 31 is communicatively connected to the cloud server. During the actual monitoring process of the line and / or tower, the camera module 6 can capture the main monitoring image of the line and / or tower in real time; the image processor 41 can judge whether the line and / or tower is abnormal based on the main monitoring image, and obtain the corresponding judgment result; the central controller 31 can control the operation of the displacement mechanism 5, the first motor 32 and the second motor 42, and transmit the main monitoring image and the judgment result to the cloud server; the displacement mechanism 5 can drive the support 2 to move in the horizontal direction and / or vertical direction, and make the main control box 3, the monitoring box 4 and the camera module 6 move synchronously; the first motor 32 can drive the monitoring box 4 to rotate synchronously in the horizontal direction together with the camera module 6; the second motor 42 can drive the camera module 6 to rotate in the vertical direction. It can be seen from this that the present application can not only realize the movement of the camera module 6 in space (i.e., movement in the horizontal and / or vertical directions) so as to adjust the points at which the camera module 6 monitors the lines and / or towers, but can also realize the rotation of the camera module 6 360° in the horizontal direction and 360° in the vertical direction so as to adjust the angle at which the camera module 6 monitors the lines and / or towers, and the position on the lines and / or towers monitored by the camera module 6, so that the monitoring range of the lines and / or towers by the camera module 6 is wider, thereby realizing all-weather, all-round, multi-angle, and multi-point real-time monitoring of the lines and / or towers, thereby improving the monitoring effect of the lines and / or towers.
