Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, and in particular to a method, device, equipment and storage medium for electrical equipment safety early warning. Background Technology

[0002] Closing a circuit breaker with the short-circuit wire and grounding wire connected is one of the most serious electrical misoperation accidents. Because the short-circuit wire and grounding wire are temporary installations without corresponding status indicators, personnel can easily forget or overlook them. Once closed with the short-circuit wire or grounding wire connected, the consequences are unimaginable. In particular, if the short-circuit wire at the top of a handcart-type high-voltage switch is not removed, a three-phase short circuit will occur on the busbar when the handcart is moved to the working position without needing to close the circuit breaker. Since the operator is right next to the switch at this time, the danger is even greater. Conventional five-proof interlocking devices cannot prevent closing the circuit breaker with the short-circuit wire or grounding wire connected, posing a significant safety hazard. Therefore, how to effectively provide safety warnings for electrical equipment and avoid closing the circuit breaker with the short-circuit wire or grounding wire connected has become an urgent problem to be solved. Summary of the Invention

[0003] The main objective of this invention is to provide a method, device, equipment, and storage medium for electrical equipment safety early warning, aiming to solve the technical problem of how to effectively provide safety early warning for electrical equipment and avoid the problem of closing the circuit with short-circuit wires or ground wires.

[0005] Determine whether there is any electrical equipment under maintenance based on the video surveillance images of the electrical equipment;

[0006] If it exists, then determine whether there is a target electrical device with a maintenance wire installed among the electrical equipment under maintenance;

[0007] If the target electrical device exists, then the operating status of the power supply switch corresponding to the target electrical device is detected;

[0008] Safety warnings are issued for the target electrical equipment based on the test results.

[0009] Optionally, the step of determining whether there is any electrical equipment under maintenance based on the video surveillance images of the electrical equipment specifically includes:

[0010] Determine whether there is an open target cabinet door based on video surveillance images of electrical equipment;

[0011] If it exists, the first electrical device corresponding to the target cabinet door is identified, and the video surveillance image is used to determine whether there is any non-operating electrical device in the first electrical device that is not in operation.

[0012] If present, it is determined that there is electrical equipment under maintenance among the electrical equipment.

[0013] Optionally, the step of detecting the operating status of the power supply switch corresponding to the target electrical device if the target electrical device exists specifically includes:

[0014] If the target electrical equipment exists, then acquire the target monitoring image of the target electrical equipment;

[0015] Based on the target monitoring image, determine whether there is a second electrical device with a maintenance wire installed in the target electrical equipment;

[0016] If present, the operating status of the power supply switch corresponding to the second electrical device is detected.

[0017] Optionally, after the step of determining whether a second electrical device with an installation maintenance wire exists in the target electrical equipment based on the target monitoring image, the method further includes:

[0018] If it does not exist, then obtain the current monitoring image and the previous monitoring image of the electrical equipment at the current moment. The previous monitoring image is the monitoring image in which the target electrical equipment has installed maintenance wires.

[0019] The current monitoring image is compared with the previous monitoring image, and the comparison result is used to determine whether the maintenance wire installed on the target electrical equipment has been removed.

[0020] If not, then detect the operating status of the power supply switch corresponding to the target electrical equipment.

[0021] Optionally, the step of acquiring the previous monitoring image specifically includes:

[0022] Acquire a first set of monitoring images showing that maintenance wires were installed in the target electrical equipment before the current time.

[0023] Determine the monitoring time corresponding to each first monitoring image in the first monitoring image set;

[0024] Determine the time interval between each monitoring moment and the current moment;

[0025] Determine the minimum time interval among all time intervals, and use the first monitoring image corresponding to the minimum time interval as the previous monitoring image.

[0026] Optionally, the step of comparing the current monitoring image with the previous monitoring image and determining whether the maintenance wire installed on the target electrical equipment has been removed based on the comparison result specifically includes:

[0027] Determine the total number of first devices in the current monitoring image and the total number of second devices in the previous monitoring image;

[0028] When the total number of the first devices is greater than or equal to the total number of the second devices, a second set of monitoring images is determined between the current time and the previous time corresponding to the previous monitoring image;

[0029] Based on each of the second monitoring images in the second monitoring image set, determine whether the maintenance wires installed on the target electrical equipment have been removed.

[0030] Optionally, the step of determining whether the maintenance wires installed on the target electrical equipment have been removed based on each of the second monitoring images in the second monitoring image set specifically includes:

[0031] The cabinet door status is determined based on each second monitoring image in the second monitoring image set;

[0032] If the status of each cabinet door remains unchanged, it is determined that the maintenance wires installed on the target electrical equipment have been removed;

[0033] When the cabinet door status changes, it is determined that the maintenance wiring installed on the target electrical equipment has not been removed.

[0034] Optionally, the step of providing a safety warning to the target electrical equipment based on the detection results specifically includes:

[0035] When the detection result includes any power supply switch being in a power-on state, a safety warning is issued based on the target electrical equipment.

[0036] Optionally, before the step of determining, based on the video surveillance images of the electrical equipment, that there is electrical equipment under maintenance, the method further includes:

[0037] Acquire pre-trained inspection wire status recognition models, cabinet door status recognition models, equipment operation status recognition models, and equipment power-on status recognition models. The inspection wire status recognition model is used to identify whether the electrical equipment has inspection wires installed. The cabinet door status recognition model is used to identify whether the cabinet door is in the open state. The equipment operation status recognition model is used to identify whether the electrical equipment is in the operation state. The equipment power-on status recognition model is used to identify whether the electrical equipment is in the power-on state.

[0038] Furthermore, to achieve the above objectives, the present invention also provides an electrical equipment safety early warning device, the electrical equipment safety early warning device comprising:

[0039] The equipment judgment module is used to determine, based on video monitoring images of the electrical equipment, whether there is any electrical equipment under maintenance.

[0040] The device determination module is also used to determine whether, when the electrical equipment under maintenance exists, there is a target electrical equipment with maintenance wires installed in the electrical equipment under maintenance.

[0041] The status detection module is used to detect the operating status of the power supply switch corresponding to the target electrical equipment when the target electrical equipment is present.

[0042] The safety warning module is used to provide safety warnings to the target electrical equipment based on the detection results.

[0043] Furthermore, to achieve the above objectives, the present invention also proposes an electrical equipment safety early warning device, which includes: a memory, a processor, and an electrical equipment safety early warning program stored in the memory and executable on the processor. The electrical equipment safety early warning program is configured to implement the steps of the electrical equipment safety early warning method described above.

[0044] In addition, to achieve the above objectives, the present invention also proposes a storage medium storing an electrical equipment safety warning program, wherein when the electrical equipment safety warning program is executed by a processor, it implements the steps of the electrical equipment safety warning method described above.

[0045] This invention determines whether any electrical equipment under maintenance exists based on video surveillance images of the electrical equipment. If so, it further determines whether any target electrical equipment with maintenance wires installed is present within the maintenance equipment. If such target electrical equipment is present, the operating status of the corresponding energizer switch is detected, and a safety warning is issued for the target electrical equipment based on the detection results. This invention first determines whether any electrical equipment under maintenance exists based on video surveillance images. It can automatically identify the presence of maintenance equipment based on video surveillance images. If present, it determines whether any target electrical equipment with maintenance wires installed is present, and whether any target electrical equipment with short-circuit wires or grounding wires is present. If present, a safety warning is issued based on the operating status of the corresponding energizer switch. It can automatically identify the energizing behavior of the energizer switch corresponding to the target electrical equipment. When the energizer switch is energized, a safety warning is effectively issued for the target electrical equipment, preventing problems such as closing the circuit breaker with short-circuit wires or grounding wires.

[0052] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0053] Reference Figure 1 , Figure 1 This is a schematic diagram of the electrical equipment safety early warning device structure in the hardware operating environment involved in the embodiments of the present invention.

[0054] like Figure 1 As shown, the electrical equipment safety warning device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005.

The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), such as a disk storage device. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0055] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on electrical equipment safety warning devices, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0056] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and an electrical equipment safety warning program.

[0057] exist Figure 1 In the electrical equipment safety early warning device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the electrical equipment safety early warning device of the present invention can be set in the electrical equipment safety early warning device, and the electrical equipment safety early warning device calls the electrical equipment safety early warning program stored in the memory 1005 through the processor 1001 and executes the electrical equipment safety early warning method provided in the embodiment of the present invention.

[0058] Based on the aforementioned electrical equipment safety early warning device, this invention provides an electrical equipment safety early warning method, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the electrical equipment safety early warning method of the present invention.

[0059] In this embodiment, the electrical equipment safety early warning method includes the following steps:

[0060] Step S10: Determine whether there is any electrical equipment under maintenance based on the video monitoring images of the electrical equipment.

[0061] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a computer, or an electronic device or electrical equipment safety early warning device capable of performing the above functions. The following description uses the electrical equipment safety early warning device as an example to illustrate this embodiment and the subsequent embodiments.

[0062] It should be understood that electrical equipment may include high-voltage switches, high-voltage voltage transformer trucks (PT trucks), transformers, inverters, converters, high-voltage dynamic var generators (SVG), generators, etc. Video surveillance images refer to images that include electrical equipment and can be captured by cameras. This embodiment does not impose a specific limit on the number of cameras, but all video surveillance images captured by cameras must include all electrical equipment.

[0063] Understandably, "maintaining electrical equipment" refers to electrical equipment that is under maintenance, meaning that the equipment needs to be maintained and can be repaired by installing shorting wires and grounding wires.

[0064] Furthermore, in order to effectively identify the status of electrical equipment, in this embodiment, before step S10, the method further includes: acquiring a pre-trained maintenance wire status identification model, a cabinet door status identification model, an equipment operation status identification model, and an equipment power-on status identification model. The maintenance wire status identification model is used to identify whether the electrical equipment has maintenance wires installed, the cabinet door status identification model is used to identify whether the cabinet door is in the open state, the equipment operation status identification model is used to identify whether the electrical equipment is in the operation state, and the equipment power-on status identification model is used to identify whether the electrical equipment is in the power-on state.

[0065] It should be understood that this embodiment can pre-train several models capable of recognizing the state of electrical equipment. Specifically, these models may include a maintenance wire status recognition model, a cabinet door status recognition model, an equipment operation status recognition model, and an equipment power-on status recognition model. The maintenance wire status recognition model can identify whether maintenance wires are installed on the electrical equipment. The cabinet door status recognition model can identify whether the cabinet door containing the electrical equipment is open. A cabinet door refers to a cabinet door on the electrical equipment where maintenance wires can be installed. These cabinet doors do not need to be opened during normal operation and only need to be opened during maintenance. The equipment operation status recognition model can identify whether the electrical equipment is in operation. The equipment power-on status recognition model can identify whether the electrical equipment is in a power-on state.

[0066] It is understood that the maintenance conductor in this embodiment may include shorting wires and grounding wires. The process of obtaining the maintenance conductor status recognition model may involve first collecting images of electrical equipment such as high-voltage switches, PT trucks, transformers, inverters, converters, SVG, and generators with shorting wires or grounding wires installed, as well as images without shorting wires or grounding wires installed, and labeling them into two categories: "with shorting wires and grounding wires" and "without shorting wires and grounding wires". Then, the labeled images are trained using a deep learning algorithm to obtain the maintenance conductor status recognition model. Therefore, when an image is input into the above maintenance conductor status recognition model, it can be determined whether the equipment in the image has shorting wires or grounding wires installed. The process of obtaining the cabinet door status recognition model can be as follows: First, collect images of several electrical equipment cabinet doors, such as high-voltage switches, PT trucks, transformers, inverters, converters, SVG, and generators, with both open and closed doors. These images are then labeled with two categories: "cabinet door open" and "cabinet door closed." Next, a deep learning algorithm is used to train the labeled images to obtain the cabinet door status recognition model. Therefore, when an image is input into the model, the open doors in the image can be identified. The OCR algorithm is then used to recognize the name on the cabinet corresponding to that door, thus revealing the electrical equipment placed inside. The OCR algorithm is a character recognition algorithm capable of recognizing characters such as letters, numbers, and symbols.

[0067] In practical implementation, the process of obtaining the equipment operation status recognition model can be as follows: First, collect images of electrical equipment such as high-voltage switches, PT trucks, transformers, inverters, converters, SVG, and generators in operation (the cabinet door is closed when the equipment is in operation) and images of equipment not in operation. These images are then labeled with two categories: "operating" and "not operating". The labeled images are then trained using a deep learning algorithm to obtain the equipment operation status recognition model. Therefore, when an image is input into the above equipment operation status recognition model, the electrical equipment in operation in the image can be identified, and the name of the electrical equipment can be recognized by calling the OCR algorithm. The process of obtaining the equipment power-on status recognition model can involve taking pictures of electrical equipment such as high-voltage switches, PT trucks, transformers, inverters, converters, SVG, and generators during the power-on process. Each step requires taking several pictures, followed by several pictures of the equipment not in the power-on process. These pictures are then labeled with two categories: "powering on" and "not powering on". The labeled pictures are then trained using a deep learning algorithm to obtain the equipment power-on status recognition model. Therefore, when an image is input into the equipment power-on status recognition model, the electrical equipment in the image that is in the power-on state can be identified, and the OCR algorithm can be used to identify the name of the electrical equipment.

[0068] Furthermore, in order to accurately determine whether there is any electrical equipment under maintenance, in this embodiment, step S10 includes: determining whether there is a target cabinet door in an open state based on the video monitoring image of the electrical equipment; if so, determining the first electrical equipment corresponding to the target cabinet door, and determining whether there is any non-operating electrical equipment in the first electrical equipment based on the video monitoring image; if so, determining that there is electrical equipment under maintenance in the electrical equipment.

[0069] Understandably, the initial state of electrical equipment is a non-maintenance state. It is possible to determine whether there are open cabinet doors based on video surveillance images. Specifically, the video surveillance images can be input into the cabinet door status recognition model to determine whether the cabinet doors in the video surveillance images are open. This allows for the detection of whether the cabinet doors corresponding to each electrical device are open. When an open target cabinet door is detected, the first electrical device corresponding to that target cabinet door can be identified. Specifically, the device name on the cabinet corresponding to the target cabinet door can be identified through an OCR algorithm, thus identifying the first electrical device corresponding to that device name.

[0070] It should be understood that the presence or absence of the first electrical equipment can be determined based on video surveillance images. Specifically, the video surveillance image corresponding to the first equipment can be input into the equipment operation status recognition model to determine whether there is any non-operating electrical equipment among the first electrical equipment. If no such equipment exists, the maintenance status of the first electrical equipment ends. If such equipment exists, the non-operating electrical equipment can be considered as being under maintenance. In other words, the cabinet door corresponding to the maintenance electrical equipment was once open and the maintenance electrical equipment was in a non-operating state.

[0071] Step S20: If it exists, determine whether there is a target electrical device with an inspection wire installed among the electrical equipment under maintenance.

[0072] Understandably, if there are electrical devices under maintenance, it can be determined whether there are target electrical devices with maintenance wires installed. Specifically, the video monitoring image corresponding to the electrical device under maintenance can be input into the aforementioned maintenance wire status recognition model to determine whether the electrical device under maintenance has maintenance wires installed, i.e., shorting wires or grounding wires. The electrical device under maintenance with maintenance wires installed can be regarded as the target electrical device.

[0073] In this specific implementation, this embodiment does not directly identify whether the electrical equipment has maintenance wires installed. Instead, it detects whether the cabinet door is open before identifying whether maintenance wires are installed. This is because when installing shorting wires or grounding wires, the electrical equipment may have been removed from its original cabinet (e.g., the switch truck has been pulled out of the switch cabinet), and there is no equipment name on the removed electrical equipment (the equipment name is on the cabinet). At this time, the equipment cabinet door may also be closed. It is impossible to distinguish from the real-time image which cabinet the equipment with shorting wires or grounding wires originally belonged to, resulting in inaccurate results for the target electrical equipment. Therefore, it is necessary to remember which equipment cabinet doors have been opened, and as long as the equipment is not running, even if the equipment cabinet door is opened and then closed, it is still recorded that the equipment is in maintenance status.

[0074] Step S30: If the target electrical device exists, then detect the operating status of the power supply switch corresponding to the target electrical device.

[0075] It should be understood that if there is a target electrical device for installing maintenance wires, the corresponding power supply switch can be determined. Specifically, the mapping relationship between electrical devices and power supply switches can be pre-entered, and the power supply switch corresponding to the target electrical device can be determined based on the mapping relationship. One electrical device may correspond to one or more power supply switches.

[0076] In the specific implementation, after obtaining the power supply switch corresponding to the target electrical equipment, the camera where the power supply switch is located can be automatically called to detect in real time whether the power supply switch is in a power supply state or an operating state. Specifically, the video monitoring image collected by the camera can be input into the equipment power supply state recognition model to determine whether the power supply switch is in a power supply state. When the power supply switch is detected to be in an operating state, the detection of whether the power supply switch is in a power supply state is stopped.

[0077] Step S40: Issue a safety warning to the target electrical equipment based on the detection results.

[0078] Understandably, this embodiment can issue safety warnings based on the detection results. Specifically, it can issue a safety warning when the power supply switch corresponding to the target electrical equipment is in a powered-on state. The warning methods include voice, ringtone, information push, automatic dialing, etc.

[0079] Furthermore, in this embodiment, step S40 includes: when the detection result includes the operating state of any power supply switch as being in a power-on state, a safety warning is issued based on the target electrical equipment.

[0080] It should be understood that a target electrical device may have multiple power supply switches. When at least one power supply switch is in the power supply state, a safety warning needs to be issued. The relevant information of the target electrical device can also be pushed to the staff so that the staff can find the target electrical device as soon as possible.

[0081] This embodiment determines whether any electrical equipment is under maintenance based on video surveillance images of the electrical equipment. If so, it determines whether any target electrical equipment with maintenance wires installed is present within the maintenance equipment. If such target electrical equipment is present, it detects the operating status of the corresponding energizer switch and then issues a safety warning for the target electrical equipment based on the detection results. This embodiment first determines whether any electrical equipment is under maintenance based on video surveillance images. It can automatically identify the presence of maintenance equipment based on video surveillance images. If present, it determines whether any target electrical equipment with maintenance wires installed is present, and whether any target electrical equipment with short-circuit wires or grounding wires is present. If present, it issues a safety warning based on the operating status of the corresponding energizer switch. It can automatically identify the energizing behavior of the energizer switch corresponding to the target electrical equipment. When the energizer switch is energized, it effectively issues a safety warning for the target electrical equipment, preventing problems such as closing the circuit breaker with short-circuit wires or grounding wires.

[0082] refer to Figure 3 , Figure 3 This is a flowchart illustrating the second embodiment of the electrical equipment safety early warning method of the present invention.

[0083] Based on the first embodiment described above, in this embodiment, step S30 includes:

[0084] Step S301: If the target electrical device exists, acquire the target monitoring image of the target electrical device.

[0085] Understandably, if there is a target electrical device with an installed maintenance wire, a target monitoring image containing the target electrical device can be obtained.

[0086] Step S302: Determine whether there is a second electrical device with a maintenance wire installed in the target electrical equipment based on the target monitoring image.

[0087] It should be understood that the second electrical device refers to the electrical equipment within the target electrical equipment that has maintenance wires installed. After identifying the target electrical equipment with maintenance wires installed, and after maintenance is completed, the maintenance wires installed on the target electrical equipment may have already been removed. At this point, the maintenance of the target electrical equipment is complete, and there will be no closing of the circuit with short-circuit wires and grounding wires. Therefore, after identifying the target electrical equipment with maintenance wires installed, it is possible to determine whether there is still a second electrical device with maintenance wires installed within the target electrical equipment after a period of time, based on the target monitoring image. If it exists, there may be a closing of the circuit with short-circuit wires and grounding wires; if it does not exist, there will be no closing of the circuit with short-circuit wires and grounding wires.

[0088] Furthermore, in order to achieve safety monitoring when there is no second electrical device, in this embodiment, after step S302, the method further includes: if there is no second electrical device, acquiring the current monitoring image and the previous monitoring image of the electrical device at the current moment, wherein the previous monitoring image is a monitoring image in which a maintenance wire is installed in the target electrical device; comparing the current monitoring image and the previous monitoring image, and determining whether the maintenance wire installed in the target electrical device has been removed based on the comparison result; if not, detecting the operating status of the power supply switch corresponding to the target electrical device.

[0089] Understandably, if there is no second electrical device with a maintenance wire installed in the target electrical equipment, it means that the staff may have removed the maintenance wire themselves. In this case, the current monitoring image and the previous monitoring image corresponding to the electrical equipment at the current moment can be obtained. The previous monitoring image refers to the monitoring image that detected the installation of the maintenance wire in the frame closest to the current monitoring image.

[0090] It should be understood that the current monitoring image can be compared with the previous monitoring image. Specifically, the number of electrical devices and the number of cabinet doors opened in the two images can be compared. Then, based on the comparison results, it can be determined whether the maintenance wires installed on the target electrical device have been removed. If none of the objects compared between the current and previous monitoring images have changed, it indicates that the maintenance wires installed on the target electrical device have been removed. If any of the objects compared between the current and previous monitoring images have changed, it indicates that the maintenance wires installed on the target electrical device have not been removed. In this case, the operating status of the power supply switch corresponding to the target electrical device can be detected. The specific process can be referred to the first embodiment described above, and will not be elaborated further in this embodiment.

[0091] Furthermore, in order to effectively determine the previous monitoring image, in this embodiment, the step of obtaining the previous monitoring image specifically includes: obtaining a first set of monitoring images showing that the target electrical equipment has installed maintenance wires before the current time; determining the monitoring time corresponding to each first monitoring image in the first set of monitoring images; determining the time interval between each monitoring time and the current time; determining the minimum time interval among the time intervals, and taking the first monitoring image corresponding to the minimum time interval as the previous monitoring image.

[0092] It is understood that the first set of monitoring images may include several first monitoring images of target electrical equipment with installed maintenance wires acquired before the current time, that is, the target electrical equipment in the first monitoring image includes the installed maintenance wires.

[0093] It should be understood that the monitoring time refers to the acquisition time corresponding to each first monitoring image in the first monitoring image set. Then, the time interval between each monitoring time and the current time is determined. The minimum time interval refers to the minimum value among the above time intervals. The first monitoring image corresponding to the minimum time interval is the previous monitoring image.

[0094] Furthermore, in order to effectively compare the current monitoring image with the previous monitoring image, in this embodiment, the step of comparing the current monitoring image with the previous monitoring image and determining whether the maintenance wire installed on the target electrical equipment has been removed based on the comparison result specifically includes: determining the total number of a first device in the current monitoring image and the total number of a second device in the previous monitoring image; when the total number of the first device is greater than or equal to the total number of the second device, determining a second set of monitoring images between the current time and the previous time corresponding to the previous monitoring image; and determining whether the maintenance wire installed on the target electrical equipment has been removed based on each second monitoring image in the second set of monitoring images.

[0095] It should be noted that the first total number of devices refers to the total number of electrical devices and the total number of detached cabinets contained in the current monitoring image. A detached cabinet refers to an electrical device that has been removed from its original cabinet. If an electrical device has been removed from its original cabinet, the total number of devices is 2; if the electrical device has not been removed from its original cabinet, the total number of devices is 1. The second total number of devices refers to the total number of electrical devices and the total number of detached cabinets contained in the previous monitoring image.

[0096] Understandably, when the total number of the first devices is greater than or equal to the total number of the second devices, all monitoring images between the current moment and the moment before the previous monitoring image was acquired can be determined to form a second monitoring image set. The second monitoring image set includes the current monitoring image and the previous monitoring image. Then, based on each second monitoring image in the second monitoring set, it can be further determined whether the maintenance wires installed on the target electrical equipment have been removed.

[0097] Furthermore, in order to effectively determine whether the maintenance wires installed on the target electrical equipment have been removed, in this embodiment, the step of determining whether the maintenance wires installed on the target electrical equipment have been removed based on each of the second monitoring images in the second monitoring image set specifically includes: determining the cabinet door status based on each of the second monitoring images in the second monitoring image set; determining that the maintenance wires installed on the target electrical equipment have been removed when the cabinet door status remains unchanged; and determining that the maintenance wires installed on the target electrical equipment have not been removed when there is a change in the cabinet door status.

[0098] It should be understood that in this embodiment, the cabinet door status can be determined by each second monitoring image in the second monitoring image set. Specifically, the cabinet door status can be determined by the cabinet door status recognition model, and the cabinet door status may include an open state and a closed state.

[0099] Understandably, when the cabinet door status corresponding to each of the second monitoring images remains unchanged (i.e., all are either open or closed), it is determined that the maintenance wires installed on the target electrical equipment have been removed. Conversely, when the status of at least one cabinet door corresponding to each of the second monitoring images changes, it is determined that the maintenance wires installed on the target electrical equipment have not been removed. Determining the total number of devices and cabinet door status in the monitoring images is to rule out the possibility that electrical equipment with jumper wires or grounding wires installed has been returned to the cabinet or that the cabinet door is closed, making the jumper wires or grounding wires invisible.

[0100] Step S303: If it exists, then detect the operating status of the power supply switch corresponding to the second electrical equipment.

[0101] It should be understood that if there is a second electrical device with an installed maintenance conductor, the operating status of the corresponding power supply switch of the second electrical device should be detected, which can be done through the device power supply status identification model.

[0102] In the specific implementation, refer to Figure 4 , Figure 4 This is a schematic diagram of the overall process of an embodiment of the electrical equipment safety early warning method of the present invention. Figure 4As shown, a model for recognizing the status of maintenance conductors, cabinet doors, equipment operation, and equipment power supply can be pre-trained. Real-time video surveillance images of electrical equipment such as switch rooms, transformers, inverters, converters, SVG, and generators are acquired. The system then determines whether the electrical equipment is currently under maintenance. Typically, the initial state of the equipment is non-maintenance. If not, the cabinet door status recognition model checks if the cabinet door is open. If it is, the equipment operation status recognition model checks if the equipment is in operation. If so, the maintenance status is considered complete, and the system returns to the step of checking if the cabinet door is open. If not, the equipment is considered under maintenance and recorded. The maintenance status recognition model then checks if any maintenance conductors (short-circuit wires or grounding wires) are installed on the electrical equipment in the video surveillance image. If so, the equipment is considered to be under maintenance. If electrical equipment has been fitted with a short-circuit wire or grounding wire, the system uses a maintenance wire status recognition model to determine if any electrical equipment with a short-circuit wire or grounding wire is still present in the video surveillance image. If not, it checks if the total number of devices in the video surveillance image has decreased. If not, it checks if the status of the equipment cabinet door in the video surveillance image has changed. If not, the process ends, indicating that there is no electrical equipment with a maintenance wire installed, and there will be no closing of the circuit breaker with a short-circuit wire or grounding wire. If electrical equipment with a short-circuit wire or grounding wire is still present in the video surveillance image, the system automatically associates the corresponding power supply switch with the installed grounding wire or short-circuit wire based on the pre-recorded correspondence between electrical equipment and power supply switches. It also automatically calls the monitoring camera where the power supply switch is located based on the pre-recorded correspondence between monitoring cameras and power supply switches. The system uses a power supply status recognition model to detect if any power supply switch corresponding to the installed short-circuit wire or grounding wire is in a power-on state. If so, a safety warning is issued.

[0103] This embodiment acquires a target monitoring image of the target electrical equipment when it exists, and then determines whether a second electrical device with a maintenance wire is installed within the target electrical equipment based on the target monitoring image. If so, it detects the operating status of the power supply switch corresponding to the second electrical device. In this embodiment, when a target electrical equipment with a maintenance wire is present, it determines whether a second electrical device with a maintenance wire is also present within the target electrical equipment based on the target monitoring image. This allows it to determine whether the maintenance wire installed on the target electrical equipment has been removed. If a second electrical device with a maintenance wire has not been removed, it detects the operating status of the power supply switch corresponding to the second electrical device, automatically identifying the power supply behavior of the power supply switch corresponding to the second electrical device.

[0104] Reference Figure 5 , Figure 5This is a structural block diagram of the first embodiment of the electrical equipment safety early warning device of the present invention.

[0105] like Figure 5 As shown, the electrical equipment safety early warning device proposed in this embodiment of the invention includes:

[0106] Equipment judgment module 10 is used to determine, based on video monitoring images of electrical equipment, whether there is electrical equipment under maintenance.

[0107] The device judgment module 10 is also used to determine whether there is a target electrical device with a maintenance wire installed in the electrical device under maintenance when the electrical device under maintenance exists.

[0108] The status detection module 20 is used to detect the operating status of the power supply switch corresponding to the target electrical equipment when the target electrical equipment is present.

[0109] The safety warning module 30 is used to provide safety warnings to the target electrical equipment based on the detection results.

[0110] This embodiment determines whether any electrical equipment is under maintenance based on video surveillance images of the electrical equipment. If so, it determines whether any target electrical equipment with maintenance wires installed is present within the maintenance equipment. If such target electrical equipment is present, it detects the operating status of the corresponding energizer switch and then issues a safety warning for the target electrical equipment based on the detection results. This embodiment first determines whether any electrical equipment is under maintenance based on video surveillance images. It can automatically identify the presence of maintenance equipment based on video surveillance images. If present, it determines whether any target electrical equipment with maintenance wires installed is present, and whether any target electrical equipment with short-circuit wires or grounding wires is present. If present, it issues a safety warning based on the operating status of the corresponding energizer switch. It can automatically identify the energizing behavior of the energizer switch corresponding to the target electrical equipment. When the energizer switch is energized, it effectively issues a safety warning for the target electrical equipment, preventing problems such as closing the circuit breaker with short-circuit wires or grounding wires.

[0111] It should be noted that the workflow described above is merely illustrative and does not limit the scope of protection of this invention. In practical applications, those skilled in the art can select some or all of the workflow to achieve the purpose of this embodiment according to actual needs, and no restrictions are imposed here.

[0112] In addition, for technical details not described in detail in this embodiment, please refer to the electrical equipment safety early warning method provided in any embodiment of the present invention, which will not be repeated here.

[0113] Based on the first embodiment of the electrical equipment safety early warning device of the present invention, a second embodiment of the electrical equipment safety early warning device of the present invention is proposed.

[0114] In this embodiment, the device judgment module 10 is further configured to determine whether there is a target cabinet door in an open state based on the video monitoring image of the electrical equipment; if there is, the first electrical equipment corresponding to the target cabinet door is identified, and the first electrical equipment is determined to be in an inactive state based on the video monitoring image; if there is, the electrical equipment is determined to be in a maintenance state.

[0115] Furthermore, the status detection module 20 is also used to acquire a target monitoring image of the target electrical equipment when the target electrical equipment exists; determine whether there is a second electrical equipment with a maintenance wire installed in the target electrical equipment based on the target monitoring image; if there is, detect the operating status of the power supply switch corresponding to the second electrical equipment.

[0116] Furthermore, the status detection module 20 is also used to acquire the current monitoring image and the previous monitoring image of the electrical equipment at the current moment when the second electrical equipment is not present, wherein the previous monitoring image is a monitoring image in which maintenance wires are installed in the target electrical equipment; compare the current monitoring image and the previous monitoring image, and determine whether the maintenance wires installed in the target electrical equipment have been removed based on the comparison result; if not, detect the operating status of the power supply switch corresponding to the target electrical equipment.

[0117] Furthermore, the status detection module 20 is also used to acquire a first set of monitoring images showing that there are maintenance wires installed in the target electrical equipment before the current time; determine the monitoring time corresponding to each first monitoring image in the first set of monitoring images; determine the time interval between each monitoring time and the current time; determine the minimum time interval among the time intervals, and use the first monitoring image corresponding to the minimum time interval as the previous monitoring image.

[0118] Furthermore, the status detection module 20 is also used to determine the total number of first devices in the current monitoring image and the total number of second devices in the previous monitoring image; when the total number of first devices is greater than or equal to the total number of second devices, determine the set of second monitoring images between the current time and the previous time corresponding to the previous monitoring image; and determine whether the maintenance wires installed on the target electrical equipment have been removed based on each second monitoring image in the set of second monitoring images.

[0119] Furthermore, the status detection module 20 is also used to determine the cabinet door status based on each of the second monitoring images in the second monitoring image set; when the status of each cabinet door remains unchanged, it is determined that the maintenance wire installed on the target electrical equipment has been removed; when there is a change in the cabinet door status, it is determined that the maintenance wire installed on the target electrical equipment has not been removed.

[0120] Furthermore, the safety warning module 30 is also used to issue a safety warning based on the target electrical equipment when the detection result includes the operating state of any power supply switch being in a power-on state.

[0121] Furthermore, the equipment judgment module 10 is also used to acquire pre-trained maintenance wire status recognition model, cabinet door status recognition model, equipment operation status recognition model, and equipment power-on status recognition model. The maintenance wire status recognition model is used to identify whether the electrical equipment has maintenance wires installed, the cabinet door status recognition model is used to identify whether the cabinet door is in the open state, the equipment operation status recognition model is used to identify whether the electrical equipment is in the operation state, and the equipment power-on status recognition model is used to identify whether the electrical equipment is in the power-on state.
