[0002] The environment around the substation is suitable for the growth of small animals. Small animals have a great impact on the safe operation of the electrical equipment in the substation. If animals such as rats and wild cats climb onto the electrical equipment, the insulation of the electrical equipment to the ground will be reduced, which may easily cause single-phase grounding of the equipment and even cause phase-to-phase short circuit. It may also cause accidents such as substation switch tripping, biting network cables and causing communication interruption of protection devices. Therefore, it is necessary to monitor the environment around the electrical equipment in the substation to prevent small animals from invading.

[0003] Existing monitoring devices use infrared thermal imaging temperature measurement technology to sense animals and collect images of invading small animals through cameras for background identification and confirmation. However, due to the limited monitoring range of the camera and the difficulty in predicting the intrusion location of the small animals, it is difficult to accurately obtain images of the invading small animals.

[0030] Example

[0031] Reference Figure 1-Figure 5 The present embodiment provides a monitoring device for preventing small animals from intruding into a substation, including a mounting base 110 with a cavity, a vertical rotating shaft 120 is arranged in the mounting base 110, a driving mechanism 130 for driving the rotating shaft 120 to rotate is arranged in the mounting base 110, the rotating shaft 120 movably passes through the top of the mounting base 110 and is connected to a shell 140, an infrared sensor 150 and a camera 160 are arranged on one side wall of the shell 140, a sound source locator 170 is arranged on the top of the shell 140, the sound source locator 170 is electrically connected to a controller 180 located in the shell 140, and the driving mechanism 130, the infrared sensor 150 and the camera 160 are all electrically connected to the controller 180.

[0032] In this embodiment, the sound source locator 170 can sense the abnormal sound emitted by the invasion of small animals, and locate the direction of the sound source of the abnormal sound, and then send the located sound source direction signal to the controller 180. The controller 180 processes the signal and sends a control signal to the driving mechanism 130 to control the driving mechanism 130 to drive the rotating shaft 120 to rotate a certain angle, that is, to drive the shell 140 and the infrared sensor 150 and the camera 160 on the outside to synchronously rotate the corresponding angle toward the direction of the sound source of the abnormal sound, so that the infrared sensor 150 and the camera 160 are facing the direction of the sound source of the abnormal sound. At this time, the infrared sensor 150 senses whether there is a small animal, and after sensing, the sensing signal is sent to the controller 180. The controller 180 can control the camera 160 to collect image data of the invading small animals, thereby accurately obtaining images of invading small animals at different directions in the surrounding environment of the substation.

[0033] It should be noted that if the located sound source is within the working range of the infrared sensor 150 and the camera 160, there is no need to rotate the shell 140; when the image data acquisition is completed, the driving mechanism 130 drives the rotating shaft 120 to rotate the shell 140 and the outer infrared sensor 150 and the camera 160 to the initial position. Therefore, each time the abnormal sound source of the small animal is located, the angle between the position of the abnormal sound source and the initial position is calculated to obtain the angle that the rotating shaft 120 needs to rotate; the sound source locator 170 is a prior art, for example, an acoustic imager of model Bionic XS-56Array can be used, which consists of a combined replaceable microphone array and acoustic positioning software. Different array sizes and shape designs make the array cover a wider span of acoustic imaging frequency bands, and use high-resolution beamforming technology to quickly and accurately locate the sound source position; the controller 180 has a built-in MCU chip, and its model can be STM32WL, which has a Semtech-based The sub-GHz radio capabilities of the SX126x can meet the needs of various low-power wide area network (LPWAN) wireless applications.

[0034] As an optional embodiment, the driving mechanism 130 includes a first motor 131 arranged in the mounting base 110, the first motor 131 is electrically connected to the controller 180, the first motor 131 is connected to a driving gear 132, the driving gear 132 is meshingly connected to a driven gear 133 fixedly sleeved on the rotating shaft 120, and the bottom of the rotating shaft 120 is movably connected to the inner bottom of the mounting base 110 through a bearing.

[0035] In this embodiment, when the rotating shaft 120 needs to be driven to rotate, the first motor 131 drives the driving gear 132 and the driven gear 133 to rotate, thereby driving the rotating shaft 120 to rotate synchronously, realizing automatic control and meeting the use requirements. It should be noted that the first motor 131 here adopts a stepping motor or a servo motor, which can accurately control the speed and direction to meet the use requirements.

[0036] As an optional embodiment, a mounting plate 190 is connected to one side of the camera 160, and the mounting plate 190 is connected to a swing rod 210. A section of the swing rod 210 movably extends into the shell 140. A movable groove 141 cooperating with the swing rod 210 is provided on the side wall of the shell 140. A horizontally arranged support rod 220 is provided on the inner wall of the movable groove 141. The support rod 220 radially moves through the swing rod 210. One end of the swing rod 210 located in the shell 140 is connected to a swing mechanism 230. The swing mechanism 230 is used to drive the swing rod 210 to swing around the axis of the support rod 220.

[0037] In this embodiment, when the camera 160 rotates to the direction where the small animal makes an unusual sound, there may still be a situation where the small animal invades a higher or lower location and exceeds the shooting range of the camera 160. At this time, the first image is taken first and image recognition is performed. If the small animal is not recognized, the swing mechanism 230 drives the swing rod 210 to swing up and down around the axis of the support rod 220, thereby driving the camera 160 to swing up and down, thereby adjusting the upper and lower shooting ranges of the camera 160 until the camera 160 captures the image of the small animal, further improving the accuracy of obtaining the image of the small animal.

[0038] As a first optional embodiment, the swing mechanism 230 includes a hinge seat 231 arranged at the bottom of the shell 140, the hinge seat 231 is hinged with a first telescopic cylinder 232, the top of the first telescopic cylinder 232 is hinged to the end of the support rod 220, and the first telescopic cylinder 232 is electrically connected to the controller 180.

[0039] In this embodiment, when it is necessary to drive the swing rod 210 to rotate, the swing rod 210 can be driven to rotate around the swing rod 210 through the telescopic effect of the first telescopic cylinder 232. At the same time, the first telescopic cylinder 232 adaptively swings a certain angle accordingly, thereby achieving the effect of automatically rotating the swing rod 210.

[0040] As a second optional embodiment, the swing mechanism 230 includes a second telescopic cylinder 233 arranged on the top of the shell 140, the bottom of the second telescopic cylinder 233 is in contact with the radial upper surface of the swing rod 210, and the second telescopic cylinder 233 is electrically connected to the controller 180; the bottom of the second telescopic cylinder 233 is movably connected to a guide pulley 234, and the guide pulley 234 is in contact with the radial upper surface of the swing rod 210.

[0041] In the present embodiment, since the camera 160 has a certain weight and the weight of the camera 160 is greater than the weight of the swing arm 210, in the absence of an external force acting on the swing arm 210, the camera 160 will swing downward, while a section of the swing arm 210 will swing upward and tilt. Therefore, the guide pulley 234 at the bottom of the second telescopic cylinder 233 contacts the radial upper surface of the swing arm 210, thereby forming resistance for a section of the swing arm 210 that has a tendency to swing upward. When the second telescopic cylinder 233 is shortened, the camera 160 swings downward under the action of its own weight, thereby making the shooting range of the camera 160 aimed at a low place. When the second telescopic cylinder 233 is extended, a thrust is generated on the swing arm 210 to make it rotate downward. By utilizing the principle of leverage, the camera 160 is driven to swing upward, so that the shooting range of the camera 160 is aimed at a high place, thereby realizing automatic adjustment of the upper and lower shooting ranges of the camera 160. Moreover, the guide pulley 234 contacts the swing arm 210 here, thereby reducing wear.

[0042] As a third optional embodiment, the swing mechanism 230 includes a second motor 235 arranged at the bottom of the shell 140, the second motor 235 is electrically connected to the controller 180, the second motor 235 is connected to a winding wheel 236, a traction line 237 is wound around the winding wheel 236, the other end of the traction line 237 is connected to a connector 238, and the connector 238 is connected to the end of the swing rod 210.

[0043] In the present embodiment, similarly, utilizing the self-weight of the camera 160 and the principle of leverage, the winding wheel 236 can reel in and release the traction line 237 by rotating the second motor 235 in different directions. When releasing the line, the camera 160 swings downward under the action of its own weight. When reeling in the line, the traction line 237 generates a pulling force on the swing rod 210 to rotate it downward, thereby driving the camera 160 to rotate upward, thereby realizing automatic adjustment of the upper and lower shooting ranges of the camera 160.

[0044] As an optional embodiment, at least one sound and light alarm 240 is also provided on the outer wall of the shell 140. The sound and light alarm 240 is electrically connected to the controller 180. When the image recognizes that there are indeed invading small animals, the sound and light alarm 240 is activated to drive away the small animals, thereby preventing the invasion of small animals.

[0045] As an optional implementation, a plurality of drainage holes 111 are provided at the bottom of the mounting seat 110 to prevent rainwater from flowing into the mounting seat 110 and accumulating, thereby preventing internal parts of the mounting seat 110 from being soaked by rainwater.

[0046] As an optional embodiment, a wireless communication module (not shown) is also provided in the housing 140, and the wireless communication module is electrically connected to the controller 180. The wireless communication module can have a text message alarm function, thereby reminding the staff of the backstage monitoring room that small animals have invaded the substation. It should be noted that the wireless communication module here can adopt a WiFi module, an LTE module, a Zigbee module or an NB-IoT module, which can meet the use requirements.
