[0021] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] An unattended substation inspection and monitoring device according to an embodiment of this application includes: The main body of the inspection vehicle is 1. A base 2 that drives the camera to rotate horizontally is mounted on the main body of the inspection vehicle. A box 4 is mounted on the top of the base 2. A camera component 5 that enables simultaneous monitoring in four directions is mounted on the box 4. The camera assembly 5 includes a longitudinal adjustment assembly 51 fixed inside the housing 4. A first rotating shaft 52 is rotatably mounted on the upper ends of two non-adjacent sides of the longitudinal adjustment assembly 51. A first mounting base 54 is connected to the outer wall of one end of the first rotating shaft 52, and a first camera 55 is mounted on the first mounting base 54. The lower ends of the other two non-adjacent sides of the longitudinal adjustment component 51 are each rotatably mounted with a second rotating shaft 58. A second mounting base 510 is connected to the outer wall of one end of the second rotating shaft 58, and a second camera 511 is mounted on the second mounting base 510. The sound positioning module includes a microphone, a locator, and a controller. The microphone is located on the outer periphery of the housing 4, the locator is located on the main body 1 of the inspection vehicle, and the controller is connected to the microphone, the first camera 55, the second camera 511, and the locator.

[0023] The unattended substation inspection and monitoring device of this application improves inspection efficiency by facilitating the adjustment of image monitoring angle and monitoring of abnormal sounds.

[0024] Specifically, such as Figures 1 to 5 As shown, the lower end of the main body 1 of the inspection vehicle is equipped with at least three wheels. The interior of the main body 1 of the inspection vehicle is equipped with a drive assembly that drives the wheels to rotate. The drive assembly driving the wheels to rotate is existing technology and will not be described in detail here. The interior of the main body 1 of the inspection vehicle is also equipped with sensors for monitoring the temperature and humidity, smoke and gas leaks in the substation, as well as an alarm system for alarm processing when abnormal situations are detected. The alarm system includes multiple methods such as audible and visual alarms, voice alarms, and SMS alarms to promptly notify maintenance personnel of abnormal situations.

[0025] The main body 1 of the inspection vehicle is equipped with a base 2 that drives the camera to rotate horizontally. A box 4 is installed on the top of the base 2, and a camera assembly 5 is installed on the box 4 to achieve simultaneous monitoring in four directions (front, back, left, and right of the main body 1 of the inspection vehicle). The camera assembly 5 includes a longitudinal adjustment assembly 51 fixed inside the housing 4. The longitudinal adjustment assembly 51 is used to adjust the vertical shooting angle of the four cameras. The upper ends of the two non-adjacent sides of the longitudinal adjustment assembly 51 are rotatably mounted with a first rotating shaft 52. The two first rotating shafts 52 rotate in opposite directions. A first mounting base 54 is connected to the outer wall of one end of the first rotating shaft 52. A first camera 55 is mounted on the first mounting base 54. The lower ends of the other two non-adjacent sides of the longitudinal adjustment component 51 are each rotatably mounted with a second rotating shaft 58. The two second rotating shafts 58 rotate in opposite directions. A second mounting base 510 is connected to the outer wall of one end of the second rotating shaft 58. A second camera 511 is mounted on the second mounting base 510.

[0026] There are two second cameras 511 in the front-back direction to collect images in the front-back direction, and two first cameras 55 in the left-right direction to collect images in the left-right direction. The first rotating shaft 52 and the second rotating shaft 58 can rotate relative to the main body 1 of the inspection vehicle, so as to facilitate the adjustment of the camera angle for better image monitoring.

[0027] The sound positioning module includes a microphone, a locator, and a controller. The microphone is located on the outer periphery of the housing 4, the locator is located on the main body 1 of the inspection vehicle, and the controller is connected to the microphone, the first camera 55, the second camera 511, and the locator. The microphone is located on the outer periphery of the housing 4.

[0028] The microphone is suitable for collecting noise generated by equipment during inspections. The controller uses the sound volume during inspections to determine abnormal areas and abnormal equipment, while simultaneously monitoring abnormal equipment through image acquisition. The controller also includes a wireless transmission module to upload camera and microphone data to the monitoring system for manual review and post-incident analysis.

[0029] The unmanned substation inspection and monitoring device of this application embodiment has a microphone in the sound positioning module installed on the outer periphery of the enclosure 4, which can collect the noise emitted by the equipment during inspection in real time. The controller can quickly and accurately determine abnormal areas and abnormal equipment by analyzing the sound intensity. For example, when a piece of equipment in the substation malfunctions and emits an abnormal sound, the microphone can promptly capture the sound. The controller determines the approximate location of the faulty equipment based on the sound characteristics and intensity, providing important clues for subsequent troubleshooting and handling. The controller is connected to the first camera 55 and the second camera 511. After determining the abnormal area through sound positioning, it can immediately call the camera in the corresponding area to collect images, further monitoring the abnormal equipment. This image and sound collaborative monitoring method can evaluate the equipment status from multiple dimensions, improving the accuracy and reliability of fault detection. For example, for some equipment where the fault type and severity are difficult to determine solely by sound, image monitoring can intuitively show changes in the equipment's appearance, operating status, and other information, providing maintenance personnel with more comprehensive fault information and improving inspection efficiency. Camera data and microphone data are uploaded to the monitoring system in real time. Maintenance personnel can view the equipment status and environmental information within the substation in real time from a remote monitoring center, eliminating the need for on-site inspections and further improving inspection efficiency. Furthermore, the data upload function facilitates the storage and analysis of inspection data, providing data support for equipment maintenance and management.

[0030] In some embodiments, multiple microphones are used, spaced apart around the circumference of the inspection vehicle body 1. This arrangement allows the microphones to collect sound signals from different directions and angles. This layout enables the microphones to cover the space surrounding the inspection vehicle, avoiding blind spots that might exist with a single microphone. For example, when an abnormal sound originates from the side or rear of the inspection vehicle, the microphone located at the corresponding position can promptly capture the sound, ensuring that no sound information from any direction is missed, thereby achieving comprehensive monitoring of the sound environment within the substation.

[0031] Furthermore, microphones located at different positions will capture different sound signals due to variations in their distance from the sound source and their angle. By comprehensively analyzing the sound data collected by multiple microphones, richer sound details can be obtained. For example, in complex sound scenarios, such as when multiple devices are operating simultaneously and some devices malfunction, multiple microphones can record the sound characteristics emitted by different devices, helping to more accurately identify the location of abnormal sounds.

[0032] Furthermore, when equipment in the substation emits abnormal sounds, the sound travels to each microphone at a certain speed. Since the microphones are located at different spatial positions, the time it takes for the sound to reach each microphone varies. By measuring these time differences and combining them with the known position information of the microphones provided by the locator, the controller can use triangulation or other positioning algorithms to calculate the approximate location of the abnormal sound. For example, ideally, if there are three or more non-collinear microphones, the specific coordinates of the sound source in a plane or space can be determined by calculating the time difference of sound arrival at each microphone, greatly improving the accuracy of sound localization.

[0033] In some embodiments, the base 2 includes a platform 21 rotatably mounted on the main body 1 of the inspection vehicle. A groove 22 is provided on the platform 21, and a support column 23 is inserted into the inside of the groove 22. The box 4 is connected to the top of the support column 23.

[0034] Furthermore, the inspection trolley body 1 is equipped with a lateral adjustment component 3 that drives the base 2 to rotate. The lateral adjustment component 3 includes a motor 31 installed inside the inspection trolley body 1. A first gear 32 is sleeved on the output shaft of the motor 31, and a gear ring 33 is sleeved on the outer wall of the base 21. The first gear 32 meshes with the gear ring 33.

[0035] Specifically, such as Figures 1 to 5 As shown, the base 2 includes a platform 21 rotatably mounted on the main body 1 of the inspection vehicle. The platform 21 is frustum-shaped, with a cylindrical bottom. A groove 22 is provided on the platform 21, and a support column 23 is inserted into the groove 22. The housing 4 is connected to the top of the support column 23. The motor 31 drives the first gear 32 to rotate. With the cooperation of the first gear 32 and the gear ring 33, the base 2 rotates as a whole, which in turn drives the housing 4 and the four cameras mounted on the housing 4 to rotate laterally, so as to facilitate the recording of the substation operation status around the main body 1 of the inspection vehicle.

[0036] In some embodiments, the side of the housing 4 is provided with a plurality of through holes 41, and the first rotating shaft 52 and the second rotating shaft 58 are at least partially rotatably mounted inside the through holes 41.

[0037] A first bevel gear 53 is fitted onto the outer wall of each of the two first rotating shafts 52. A first rotating rod 56 is rotatably installed inside the housing 4. A second bevel gear 57 is fitted onto the outer wall of the first rotating rod 56. The first bevel gear 53 and the second bevel gear 57 mesh with each other.

[0038] Multiple through holes 41 are provided on the side of the housing 4, and the first rotating shaft 52 and the second rotating shaft 58 are rotatably installed inside the through holes 41.

[0039] Two first bevel gears 53 are fitted onto the outer walls of the two first rotating shafts 52. A first rotating rod 56 is rotatably mounted inside the housing 4. A second bevel gear 57 is fitted onto the outer wall of the first rotating rod 56. The first bevel gear 53 meshes with the two second bevel gears 57. Multiple through holes 41 are provided on the side of the housing 4. The first rotating shaft 52 and the second rotating shaft 58 are rotatably mounted inside the through holes 41.

[0040] A first bevel gear 53 is fitted onto the outer wall of each of the two first rotating shafts 52. A first rotating rod 56 is rotatably installed inside the housing 4. A second bevel gear 57 is fitted onto the outer wall of the first rotating rod 56. The first bevel gear 53 meshes with the two second bevel gears 57.

[0041] A third bevel gear 59 is sleeved on the outer wall of the two second rotating shafts 58. A second rotating rod 512 is rotatably installed inside the housing 4. A fourth bevel gear 513 is sleeved on the outer wall of the second rotating rod 512. The third bevel gear 59 meshes with the two fourth bevel gears 513.

[0042] The longitudinal adjustment component 51 includes a hollow column 5101, and a liftable connecting bar 5104 is installed inside the hollow column 5101. The connecting bar 5104 is located at one corner inside the hollow column 5101, and a first rack 5105 and a second rack 5106 are respectively installed on the adjacent side walls of the connecting bar 5104.

[0043] One end of the first rotating rod 56 passes through the hollow column 5101 and is fitted with the second gear 5107. One end of the second rotating rod 512 passes through the hollow column 5101 and is fitted with the third gear 5108. The second gear 5107 meshes with the first rack 5105, and the third gear 5108 meshes with the second rack 5106.

[0044] Specifically, such as Figures 1 to 5As shown, the motor 5102 drives the connecting bar 5104 to rise and fall via the lead screw 5103, which in turn drives the first rack 5105 and the second rack 5106 to rise and fall, thereby driving the second gear 5107 and the third gear 5108 to rotate. The second gear 5107 drives the first rotating rod 56 to rotate. The first rotating rod 56 drives the first rotating shaft 52 to rotate via the first bevel gear 53 and the second bevel gear 57, thereby realizing the up and down adjustment of the shooting angle of the first camera 55. Similarly, the third gear 5108 drives the second rotating rod 512 to rotate. The second rotating rod 512 drives the second rotating shaft 58 to rotate with the cooperation of the third bevel gear 59 and the fourth bevel gear 513, thereby realizing the up and down adjustment of the shooting angle of the second camera 511.

[0045] Furthermore, a lead screw 5103 is rotatably mounted inside the hollow column 5101, and a motor 5102 is mounted on the housing 4. The motor 5102 is configured as a forward and reverse motor 5102. The output shaft of the motor 5102 is connected to the top of the lead screw 5103, and a connecting bar 5104 is threaded onto the outer wall of the lead screw 5103.

[0046] During use, the main body 1 of this inspection trolley ensures the stable operation of the four cameras (two first cameras 55 and two second cameras 511) while inspecting within the substation, and adjusts the shooting angles of the four cameras in a timely manner according to specific circumstances. Specifically: The motor 31 drives the first gear 32 to rotate. With the cooperation of the first gear 32 and the gear ring 33, the base 2 rotates as a whole, which in turn drives the housing 4 and the four cameras mounted on the housing 4 to rotate laterally, so as to capture the operating status of the substation around the main body 1 of this inspection vehicle. Simultaneously, motor 5102 operates, driving connecting bar 5104 to rise and fall via lead screw 5103, which in turn drives first rack 5105 and second rack 5106 to rise and fall. Since second gear 5107 meshes with first rack 5105 and third gear 5108 meshes with second rack 5106, both gears can rotate. Furthermore, second gear 5107 drives first rotating rod 56 to rotate, which in turn drives first rotating shaft 52 to rotate via first bevel gear 53 and second bevel gear 57, thereby achieving… The shooting angle of the first camera 55 can be adjusted up and down. Similarly, the third gear 5108 drives the second rotating rod 512 to rotate. The second rotating rod 512, with the cooperation of the third bevel gear 59 and the fourth bevel gear 513, drives the second rotating shaft 58 to rotate, thereby realizing the up and down adjustment of the shooting angle of the second camera 511. In summary, it is possible to realize that all four cameras can rotate up or down at the same time, which is convenient for monitoring the conditions at different heights of the substation. This enables multiple cameras to monitor the substation simultaneously from multiple angles and over a wide area, reducing the chance of missed detections and facilitating the discovery of potential hazards in the substation.

[0047] This application provides an embodiment of an inspection method for an unattended substation inspection and monitoring device, utilizing the aforementioned inspection device, including: Set the planned inspection route; during the inspection, acquire sound information collected by the microphone and image information collected by the camera; The controller determines whether the sound decibel level exceeds the preset range based on the collected sound information. If it does, the controller will activate the buzzer to sound an alarm and reduce the inspection speed.

[0048] Before commencing inspection, a planned inspection route needs to be established. For example, based on factors such as the distribution location, importance, and frequency of past faults of various equipment within the substation, a route covering all critical areas should be planned. The planned route can be stored in the controller of the inspection device as a guide for subsequent inspections. The inspection device moves along the planned route. During movement, the microphone on the device collects sound information from the surrounding environment in real time, while the camera captures image information of the corresponding area. The microphone can capture various sounds of equipment operation, such as the running sound of motor 31, the humming sound of transformers, etc., and may also detect abnormal sounds, such as abnormal friction sounds or discharge sounds from equipment. The camera provides intuitive visual information, helping maintenance personnel observe the appearance of the equipment, the status of indicator lights, etc.

[0049] The controller analyzes the collected sound information to determine if the sound level exceeds a preset range. This preset range is set based on the sound level of normal equipment operating within the substation and relevant safety standards. For example, for some common electrical equipment, the sound level during normal operation may be between -100 and 1000 decibels. When a sound level exceeding this range is detected, it may indicate an equipment malfunction requiring on-site inspection and handling.

[0050] Because the inspection device slows down when it detects unusual sounds, the camera has more time and opportunity to observe potentially problematic areas from multiple angles. For example, when an unusual sound is detected near a device, the inspection device can slowly move around that device, allowing the camera to capture images from different directions. This provides a more comprehensive understanding of the device's appearance and can uncover hidden signs of malfunction, such as damage to the casing or loose connections. If the sound level exceeds the preset range, the controller will immediately activate the buzzer to sound an alarm, alerting nearby personnel to a potential equipment malfunction. Simultaneously, to more thoroughly inspect areas potentially emitting abnormal sounds, the controller will reduce the inspection speed, causing the inspection device to slow its movement in the vicinity of the area, thus allowing for more accurate location of the abnormal sound's source.

[0051] The inspection method of the unattended power distribution station inspection and monitoring device according to the embodiments of this application facilitates the adjustment of the image monitoring angle, monitors abnormal sounds, and improves the efficiency of inspection. A detailed description of the method provided in this application has been given above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
