Detailed Description
Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.
As described in the background art, electrical equipment such as a switch cabinet or a ring main unit has a very wide application in the electrical field. There is a constant demand for monitoring the switching devices of such switchgear cabinets (especially closed switchgear cabinets, such as ring main units filled with SF 6) in order to be able to know the operating state (e.g. switching off, switching on, grounding or abnormal operating state) of the switches in the switchgear cabinet in real time, which is very important for the safe operation of the electrical equipment.
The conventional monitoring modes for the working devices in the cabinet mainly include two modes: one is to arrange an observation window on the cabinet body, so that on-site workers can check the working state of a switch in the cabinet body in real time through the observation window. The disadvantage of this monitoring method is that the working state of the switch in the cabinet body cannot be remotely known. The other monitoring mode is that a camera is installed in the cabinet body, so that the working state of the switch can be monitored in real time. However, this monitoring method has a disadvantage that convenient maintenance or replacement of the camera cannot be achieved, especially in the case of a closed type switch cabinet (e.g., a ring main unit filled with SF 6)).
Therefore, how to provide a monitoring device capable of monitoring the working state of the devices in the cabinet body in real time and facilitating installation and maintenance is a technical problem to be considered by those skilled in the art.
The concept of the present disclosure is to provide a video monitoring assembly adapted to be mounted on one side of an aperture of a wall plate of a cabinet of an electrical apparatus and to monitor an operating state of a device located on the other side of the wall plate through the aperture. In order to enable the installation of the video surveillance assembly in the hole, the video surveillance assembly is designed to comprise at least a transparent viewing window, an annular pressure plate and a camera module, wherein the periphery of the transparent viewing window is adapted to be pressed tightly against said wall plate around the hole by the annular pressure plate, thereby enabling a sealed covering of said hole by the transparent viewing window, while the camera module is arranged at the side of the transparent viewing window opposite to the hole and adapted to monitor the operating state of the device located at the other side of the wall plate through both the transparent portion and the hole. In this way, the camera module can be assembled independently of the transparent viewing window, so that maintenance and replacement of the camera module can be carried out independently without any influence on the sealing of the transparent viewing window in the cabinet body of the electrical equipment, which is particularly advantageous for monitoring closed switchgear cabinets (e.g. ring main units filled with SF 6).
To more clearly understand the application scenario of the video surveillance assembly of the present disclosure, fig. 1 shows a schematic side view of a device integrated with a video surveillance assembly according to an example embodiment of the present disclosure; FIG. 2 shows a front view schematic diagram of a device integrated with a video surveillance assembly according to an example embodiment of the present disclosure.
As shown in fig. 1, the video monitoring assembly 20 may be mounted outside the cabinet 10 of the apparatus 100 and adapted to monitor the operating conditions of the devices located within the cabinet 10 through holes in a wall 11 of the cabinet 10 (see fig. 5). Here, the device 100 is shown in the shape of a switchgear or ring main unit. However, it will be understood that the apparatus 100 of the present disclosure is not limited to electrical equipment such as a switchgear or ring main unit, but may include any other equipment or chamber having wall panels and suitable for monitoring, even other equipment that is not electrical equipment.
Further, it should be understood that although only a single video surveillance assembly 20 is shown in FIG. 1, this is not limiting. In other embodiments, multiple video monitoring assemblies 20 may be mounted on the outside of the cabinet 10 of the apparatus 100, and these video monitoring assemblies 20 may monitor the operating status of the same device (e.g., one switch) or different devices (e.g., different switches) within the cabinet 10.
To process video data collected from video surveillance assembly 20, device 100 may also include a processing module having various functions for display, signal processing, and/or communication. In some embodiments, the processing modules may be uniformly centralized within the enclosure 30 external to the device 100 to facilitate uniform maintenance by the personnel. In still other embodiments, the processing modules may be individually or discretely arranged, thereby providing a more flexible arrangement of processing modules. For example, the processing modules may be arranged at different locations on the cabinet 10 of the apparatus 100.
By way of example only, as shown in FIG. 2, the cassette 30 may include a display 31 that may be used to display images of the operational status of devices (e.g., various switches) captured by the video surveillance assembly 20 so that the operational status of the devices may be grasped on-site by a worker. For another example, the box 30 may further include a communication device such as a hub or a gateway, so that the image collected from the video monitoring component 20 and the collected image can be uploaded to a server or a cloud in real time, so that a worker can remotely view the working status of the devices in real time. Even in some embodiments, the staff may also check the working states of the devices in real time by connecting the terminal user equipment, such as a mobile phone, to the server or the cloud, so that the checking by the user is facilitated.
The specific structure of an example video surveillance assembly of the present disclosure will be described in detail below in conjunction with fig. 3-5.
As shown in fig. 3-5, the video surveillance assembly 20 of the present disclosure may be mounted on a wall panel 11 of the device 100. To avoid the impact on the apparatus 100, the video surveillance assembly 20 is mounted on the outer side a of the wall plate 11, and the operation of the components located on the inner side B of the wall plate 11 is achieved through the holes 114 provided in the wall plate 11. By arranging the video monitoring component in this way, the operation of the device can be maximally unaffected.
To accomplish the mounting of the video monitoring assembly 20 on the wall panel 11 and its own monitoring function, the video monitoring assembly 20 can basically include a transparent viewing window 23, an annular pressure plate 25 and a camera module 22.
The purpose of the transparent viewing window 23 is to seal the aperture 114 and allow the camera module 22 to capture images relating to the operating conditions of the devices within the cabinet 10 through both the transparent viewing window 23 and the aperture 114. To this end, the transparent viewing window 23 may be sized larger than the aperture 114 and have at least a transparent portion 231 corresponding to the aperture 114.
Further, in some embodiments, the transparent viewing window 23 may be configured to be flexible, which may facilitate sealing of the transparent viewing window 23 to the aperture. It will be appreciated, however, that this is not a limitation and that in other embodiments the transparent viewing window 23 may not be flexible. In this case, the sealing of the transparent viewing window 23 on the aperture 114 may be achieved by means of other sealing means (e.g. a sealing ring).
As shown in fig. 5, when the transparent window 23 is mounted on the wall plate 11, the peripheral edge 232 of the transparent window 23 can be tightly pressed against the wall plate 11 around the hole 114. In this way, a sealed covering of the aperture 114 from all sides by the transparent viewing window 23 can be achieved.
In some embodiments, to better ensure the sealing of the transparent viewing window 23 to the aperture 114, the sealing may also be achieved by means of a sealing ring 232. In these embodiments, the peripheral edge 232 may be provided with an annular groove 233 open facing the wall plate 11, which may be used to accommodate the annular sealing ring 29, whereby the annular sealing ring 29 may be positioned between the annular groove 233 and the wall plate 11 in a state in which the transparent viewing window 23 is pressed against the wall plate 11. In this way, the degree of sealing of the transparent viewing window 23 to the aperture 114 can be improved.
In some embodiments, as shown in FIG. 4, a mount 24 may also be attached to the side of the transparent viewing window 23 opposite the aperture 114. The placement portion 24 can be used to accommodate at least a portion of the camera module 22 to facilitate assembly between the camera module 22 and the transparent viewing window 23. In some embodiments, the seating portion 24 and the transparent viewing window 23 may be integrally molded and may be made of the same material, which may facilitate the manufacture of both the seating portion 24 and the transparent viewing window 23. It will be appreciated, however, that this is not a limitation and that in other embodiments the mounting portion 24 and the transparent viewing window 23 may be separate components, both of which may then be attached to each other by means such as gluing, welding or additional fastening means. In this way, the degree of freedom in designing both the placement portion 24 and the transparent observation window 23 can be increased.
The annular pressure plate 25 serves to secure the transparent viewing window 23 to the wall plate 11. To this end, in some embodiments, the annular pressure plate 25 may have an annular pressure cover portion 251 and an annular fastening portion 252 that are stepped from each other. The annular gland portion 251 is shaped and dimensioned to press the peripheral edge 232 of the transparent viewing window 23 tightly against the wall around the aperture 114; and the annular fastening portion 252 is adapted to be fastened to the wall plate 11 via the bolts 111, 112, thereby achieving a secure fixation of the transparent viewing window.
As shown in fig. 3 and 4, the annular pressure plate 25, together with the transparent viewing window 23, can be fastened to the surrounding wall of the hole 114 using 6 bolts 111 or 112. However, it will be understood that the number of bolts used is merely an example, and is not limiting. In other embodiments, a greater or lesser number of bolts may be used to achieve the fastening. In addition, each of the 6 bolts shown in fig. 4 is welded to the wall plate 11 in advance, and the length of 2 bolts 111 may be longer than the length of the remaining 4 bolts 112, so as to facilitate the fastening of the later-mentioned pressure shell 21 to the annular pressure plate 25. These are not required and in other embodiments the length of all the bolts may be the same or the length of each bolt may be different, provided that the length is suitable for fastening the annular pressure plate 25. Alternatively, instead of being welded to the wall plate 11, the 6 bolts may be bolted to lock the annular pressure plate 25 to the wall plate 11.
The function of the camera module 22 is to acquire images relating to the operating conditions of the devices located on the inside of the wall 11. As shown in fig. 4 and 5, the camera module 22 may generally include a camera housing 221, a circuit board 223, and a camera 225, wherein the camera housing 221 may be configured to receive the circuit board 223, the camera 225, and to allow an end of the camera 225 to protrude from the camera housing 221.
The camera housing 221 may be fitted into the placement portion 24, wherein the shape and size of the placement portion 24 may be adapted to the structure and shape of the camera housing 221. In order to achieve communication and electrical connection of the camera housing 221 with the outside, a line 28 may be provided leading out from the camera housing 221 and the placement portion 24, wherein the line 28 may include a power supply line 281 (e.g., a direct current power supply line) and a data line 282.
In a state where the camera housing 221 is assembled in the mounting portion 24, an end portion of the camera 225 protruding from the inside of the camera housing 221 faces the transparent observation window 23, and may even be pressed against the transparent observation window 23, so that the camera 225 can monitor the working state of the devices in the cabinet 10 through the transparent observation window 23 and the hole 114.
In order to prevent dust from entering from a gap between the camera housing 221 and the seating portion 24, in some embodiments, a sealing ring 224 may be provided between an outer wall of the camera housing 221 and an inner wall of the seating portion 24, thereby improving a dust-proof grade.
In some embodiments, the camera module 22 can further include at least one fill light 226, and the at least one fill light 226 can be disposed around an end of the camera 225 exposed from the camera housing 221 and function to provide illumination light for monitoring of the camera 225. This is very advantageous for the device to be monitored. It should be noted that only one fill light 226 is shown in fig. 4, but the number of fill lights 226 shown is merely an example and does not constitute any limitation to the present disclosure.
To prevent the direct light from the fill light 226 from adversely affecting the end of the camera 226 exposed from the camera housing 221, in some embodiments, the end of the camera 225 may be sleeved with a reflective rubber ring 228, and the reflective rubber ring 228 may cover at least a portion of the side of the end of the camera 225, thereby preventing the direct light from the fill light 226 from being incident into the camera 225 from the portion of the side. In this way, the quality of the image captured by camera 225 may be improved. In addition, in order to further homogenize the light output from the fill light 226, in some embodiments, the camera module 22 may further include a fill light cover 228. The fill light cover 228 may be sleeved on the camera housing 221 and have an opening allowing the camera 225 to be exposed outward therefrom. By this arrangement, the light output from the fill-in light 226 is uniform, and the image collection of the camera module 22 through the transparent viewing window 23 and the aperture 114 is not affected.
The video surveillance assembly 20 may further include a press shell 21, which functions to allow the camera module 22 to be securely locked between the press shell 21 and the transparent viewing window 23, even to allow the camera module 22 to be securely abutted against the transparent viewing window 23, which is advantageous for image acquisition by the camera 225.
To this end, in some embodiments, the press shell 21 can have a concave housing that can house at least a portion of the camera module 22. Further, in some embodiments, the concave housing may include a base plate 212 and an extended edge extending from the base plate 212 in a direction toward the wall plate 11, which may be securely locked to the annular pressure plate 25 or the wall plate 11 by means of bolts.
By way of example only, as shown in fig. 4 and 5, the extension edge may be, for example, two L-shaped extensions 211 extending from both sides of the bottom plate 212 toward the wall plate 11, respectively. Via the two L-shaped extensions 211 and the bolts 111, the press shell 21 can be locked to the annular pressure plate 25 or the wall plate 11, while the base plate 212 can be made to press the camera module 22, so that the camera module 22 can be firmly positioned between the press shell 21 and the transparent viewing window 23.
It will be understood that the structure and shape of the press shell 21 shown in fig. 4 and 5 are only examples, and that in other embodiments the shape of the press shell and the extended rim, and the number of extensions 211, may vary, as long as the press shell 21 is adapted to be fastened to the wall plate 11 or the annular pressure plate 25 and force the camera module 22 to be positioned between the press shell 21 and the transparent viewing window 23. It should be noted here that the pressing shell 21 is fastened to the wall plate 11 or the annular pressing plate 25, and the fastening of the annular pressing plate 25 to the wall plate 11 is two operations independent of each other. The tight fastening of the press shell 21 to the wall plate 11 or the annular pressure plate 25 does not affect the sealing coverage of the hole 114 by the transparent viewing window 23 with the annular pressure plate 25.
The specific structure of the video surveillance assembly 20 of the present disclosure has been described above in detail. It will be appreciated that with the video surveillance assembly 20 of the present disclosure, the camera module 22 can be easily replaced and maintained by removing the press shell 21 without affecting the sealing of the transparent viewing window 23 to the aperture 114 of the cabinet 10, since, as described above, the fastening of the press shell 21 to the wall plate 11 or the annular pressure plate 25 and the fastening of the annular pressure plate 25 to the wall plate 11 are two separate operations. Accordingly, the design of the video surveillance assembly 20 of the present disclosure is highly advantageous for sealed cabinets, such as ring main units filled with SF6, or other sealed switchgear. That is, convenient maintenance or replacement of the camera module 22 can be achieved without affecting the hermeticity of the cabinet.
It will also be appreciated that the video surveillance assembly 20 of the present disclosure may be mounted at any suitable location on a wall panel of a cabinet. Thus, in some embodiments, a plurality of video monitoring assemblies 20 may be disposed on the cabinet, and each video monitoring assembly 20 may monitor a corresponding working device and capture a corresponding image.
Further, in some embodiments, images captured by the various video surveillance components 20 may be transmitted and/or processed, such as filtering the images, transmitting the images to a display 31 for viewing on-site, transmitting the images via a gateway to a server or cloud for viewing remotely.
In still further embodiments, image recognition techniques may be employed to identify images captured by the respective video surveillance assembly 20 to output the identification results. For example, in the case where the operating device is a switch, an image recognition technique may be used to identify which of four operating states, i.e., grounding, opening, closing, or abnormal, the switch is in, and output and/or display the corresponding identification result.
For example only, a Convolutional Neural Network (CNN) algorithm may be used to perform feature extraction on the acquired switch image to determine the current operating state of the switch.
In addition, different image recognition technologies can be adopted to verify the output recognition result so as to ensure the robustness of the output result, which is beneficial to electrical equipment with higher safety requirements.
