Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, and in particular to an intelligent switchgear protection and control system. Background Technology

[0002] A switchgear is a type of electrical equipment. External lines first enter the main control switch inside the cabinet, and then enter the branch control switches. Each branch circuit is configured according to its needs. Examples include instruments, automatic control systems, motor magnetic switches, various AC contactors, etc. Some switchgear also have high-voltage and low-voltage compartments, and are equipped with high-voltage busbars, such as in power plants. Some also have underfrequency load shearing to protect the main equipment.

[0003] Intelligent switchgear refers to high-performance, high-reliability cabinets with certain self-diagnostic and automatic control capabilities, as well as network communication capabilities. Formally, it can be divided into distribution type, motor control type, and other control function type. Distribution type uses intelligent circuit breakers as the core component, with a host computer enabling remote control, telemetry, remote signaling, and remote adjustment of the distribution circuit. Motor control type uses frequency converters and intelligent motor controllers as core components to achieve optimized control of motor starting, running, and stopping. Other control type intelligent switchgear uses PLC (Programmable Logic Controller) as the core, completing various control functions in the production process. It is also the most promising product for the development of automatic control in industrial production processes. Organically combining PLC technology with traditional switchgear is an effective measure for intelligent transformation of ordinary switchgear with low investment and quick results.

[0004] Intelligent switchgear for power distribution is generally used in power systems. Regarding how to achieve protection for intelligent switchgear, the existing patent CN201110428905.5 discloses a multi-functional intelligent protection and control system for switchgear. It mainly focuses on protecting the humidity inside the switchgear and the human body after being energized. However, it is not comprehensive enough in terms of protection for the switchgear and lacks protection for the safety of personnel during maintenance and operation. Summary of the Invention

[0050] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0051] The accompanying drawings are provided to further illustrate the invention and form part of the specification. They are used in conjunction with embodiments of the invention to explain the invention and do not constitute a limitation thereof. In the drawings:

[0052] Figure 1 This is a schematic diagram of an intelligent switchgear protection and control system according to an embodiment of the present invention;

[0054] Figure 3 This is a schematic diagram of another intelligent switchgear protection and control system in an embodiment of the present invention. Detailed Implementation

[0055] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example 1

[0056] This embodiment provides an intelligent switchgear protection and control system, such as Figure 1 As shown, it includes: a first image acquisition module 1, a second image acquisition module 2, a processor 3, and a communication module 4; the first image acquisition module 1, the second image acquisition module 2, and the communication module 3 are electrically connected to the processor 4 respectively;

[0057] When the processor 3 receives the periodic inspection and maintenance instruction from the server through the communication module 4, it acquires the first image inside the cabinet through the first image acquisition module 1, analyzes the first image, and determines whether to power off each component inside the cabinet based on the analysis results.

[0058] And / or,

[0059] When the processor 3 receives the regular inspection and maintenance instruction from the server through the communication module 4, it acquires a second image outside the cabinet through the second image acquisition module 2, analyzes the second image, and determines whether to power off each component inside the cabinet based on the analysis results.

[0060] The analysis steps of the processor 3 on the first image are as follows:

[0061] The first image is segmented into regions and marked for identification, resulting in multiple region images and the components corresponding to each region image are determined.

[0062] Based on the recognition and analysis library corresponding to each component, the images of each region are recognized and analyzed to determine the corresponding state description number of each component.

[0063] When a preset state description number exists in the analysis results, the corresponding component in the cabinet is powered off, or all components in the cabinet are powered off.

[0064] The analysis steps of the processor 3 on the second image are as follows:

[0065] Perform personnel recognition on the second image; when a person is recognized, extract the image of the region corresponding to the person.

[0066] Perform marker recognition on the regional image to determine whether a preset marker exists.

[0067] Specifically, if a preset flag is present in the analysis result corresponding to the second image, power is cut off to all components in the cabinet or to the components in the cabinet corresponding to the periodic inspection and maintenance instructions.

[0068] In this embodiment, the intelligent switchgear protection control system, when dealing with regular inspections and maintenance, analyzes images of various components (including switches, circuit breakers, and electric shock protectors) inside the cabinet using the first image acquisition module 1 to determine if any component is abnormal; if an abnormality is found, power is cut off. Alternatively, the second image acquisition module 2 can analyze images of the external environment to determine if maintenance personnel have arrived; if so, power is cut off. The first image acquisition module 1 consists of one or more cameras installed inside the cabinet; the second image acquisition module 2 includes one or more cameras installed at the top of the cabinet for capturing images of the front or surrounding area of ​​the cabinet. The system analyzes the first image... The system performs area segmentation and marker recognition to obtain multiple area images and identify the components corresponding to each area image. The area segmentation rules are determined in advance based on a comprehensive analysis of the camera's location, shooting angle, and the position of the components inside the cabinet. During segmentation, the system directly follows these rules to obtain the area images corresponding to each component. Marker recognition methods include: identifying the brand and model information on each component; and retrieving the corresponding identification analysis library based on the brand and model information. This library, pre-built by professionals, has a one-to-one correspondence between status description numbers and standard images. The area images are matched with the standard images to determine the corresponding status description numbers. When a preset status description number is found in the analysis results, the corresponding component or all components in the cabinet are powered off. Specifically, power is cut off when there is a status description number corresponding to a detached wiring terminal or a status description number corresponding to burn marks. In standard routine inspection and maintenance operations, the attire of maintenance personnel is regulated, typically consisting of designated work uniforms with clearly visible markings. Processor 3's recognition of the second image involves identifying these markings; upon recognition, it confirms the arrival of maintenance personnel and initiates a power outage. To ensure the system continues to operate normally after power is cut off to the components within the cabinet, a backup power supply can be configured.

[0069] The intelligent switchgear protection and control system of the present invention analyzes the situation inside the cabinet before maintenance personnel arrive, so as to cut off the power in advance; and by analyzing the situation outside the cabinet, it determines the arrival of personnel and then cuts off the power. Before the maintenance personnel arrive, it continues to serve the power system. After the personnel arrive, it cuts off the power before opening the cabinet door, so as to ensure the safety of the maintenance personnel.

[0070] To facilitate maintenance, after the maintenance personnel open the cabinet door, the processor 3 communicates with the maintenance personnel's maintenance terminal via the communication module 4, and sends relevant information such as the reason for the power outage to the maintenance terminal (which can be a mobile phone). Example 2

[0071] To address safety concerns when scheduled inspection and maintenance instructions are not received, this embodiment provides an intelligent switchgear protection and control system, comprising: a first image acquisition module 1, a second image acquisition module 2, a processor 3, and a communication module 4; the first image acquisition module 1, the second image acquisition module 2, and the communication module 4 are electrically connected to the processor 3 respectively;

[0072] When no scheduled inspection and maintenance instructions are received, the processor 3's analysis of the second image also includes:

[0073] Perform personnel recognition on the second image; when a person is recognized, extract the image of the region corresponding to the person.

[0074] Behavioral analysis is performed on the regional images; specific analyses include: analyzing the objects held by people's hands, whether there are preset markings on people's clothing, people's movement speed, and movement direction, etc.

[0075] When the analyzed behavior falls under the preset first type of behavior, the control warning device outputs a warning message and cuts off power to all components inside the cabinet. The first type of behavior includes: holding objects such as sticks or hammers, wearing clothing without preset markings, and moving at a speed exceeding a preset threshold with the direction of movement towards the switch cabinet. This behavior indicates an intent to damage the switch cabinet; the power cut-off is to prevent electrocution during the damage. The warning message includes: "Please be aware of your behavior. The switch cabinet is electrical equipment with high voltage; please stay away."

[0076] When the analyzed behavior belongs to the preset second type of behavior, the control warning reminder device outputs a reminder message. The second type of behavior includes: holding a toolbox in hand, wearing clothing with preset standards, moving at a speed within a preset threshold range and moving in the direction of the switch cabinet. The situation corresponding to this type of behavior is emergency maintenance. At this time, it is only necessary to remind personnel to pay attention to maintenance safety. In addition, when the switch cabinet is only for one end customer, it is also possible to choose to disconnect the power to the components inside the switch cabinet.

[0077] In addition, to further analyze and control the environment around the switchgear and thus further protect safety, the second image acquisition module 2 includes a dual-axis or three-axis pan-tilt unit, with the camera mounted on the dual-axis or three-axis pan-tilt unit. When no scheduled inspection or maintenance command is received, the processor 3 controls the second image acquisition module 2 to enter cruise mode. After entering cruise mode, the processor 3 also performs the following operations:

[0078] The third image captured in cruise mode is analyzed to determine whether there is a hazard. Cruise mode controls the movement of a dual-axis or three-axis gimbal to capture images around the switch cabinet. Hazard analysis can be performed using a preset image analysis library, which involves matching the third image with standard images in the pre-built hazard analysis library to determine whether there is a hazard.

[0079] The hazardous sources are analyzed to identify hazardous areas; the images containing hazardous sources are analyzed to locate the hazardous sources, mainly based on the location of the hazardous sources in the images and the shooting status of the second image acquisition module 2 at the time of shooting, to determine the location of the hazardous sources in reality.

[0080] The system monitors the area around the danger zone and outputs a warning message when it detects that someone is about to enter the danger zone.

[0081] The monitoring and analysis steps for the hazardous area by processor 3 are as follows:

[0082] Construct a monitoring map centered on the danger zone, and then construct monitoring areas around the danger zone on the monitoring map;

[0083] Analyze and identify the fourth image containing the monitored area;

[0084] When personnel are present, their locations are determined based on the fourth image, and these locations are mapped onto the monitoring image.

[0085] When personnel enter the monitored area, a direction vector representing the direction of movement of the personnel is determined based on the current position of the personnel and the position of the personnel at the previous moment (any time span from 10 seconds to 1 minute);

[0086] Based on the direction vector, determine whether personnel are preparing to enter the danger zone.

[0087] Processor 3 determines whether personnel are preparing to enter a dangerous area and performs the following operations:

[0088] Determine the first judgment vector based on the current location of personnel and the center of the danger zone;

[0089] Based on the distance of the current personnel's location from the center of the danger zone and the size of the danger zone, the judgment threshold range and behavior scoring table are determined from a pre-built standard retrieval library. The standard retrieval library is pre-built and stores multiple judgment threshold ranges and behavior scoring tables, which are linked in pairs and associated with distance values ​​and area size range parameters as retrieval benchmarks. When the distance of the current personnel's location from the center of the danger zone matches the distance value parameter and the size of the danger zone matches the area size range parameter, the corresponding associated judgment threshold range and behavior scoring table are retrieved.

[0090] Calculate the angle between the direction vector and the first judgment vector; specifically, it can be calculated using the cosine of the vector angle.

[0091] When the included angle is within the range of the judgment threshold, the subjective intention score is determined according to the included angle query behavior scoring table;

[0092] The subjective intention scores of a consecutive preset number of users are weighted and calculated to determine the subjective intention value; the subjective intention scores are sorted in chronological order from front to back, and the corresponding weights are from smallest to largest after sorting; the continuous analysis of user behavior improves the accuracy of user behavior judgment.

[0093] When the subjective intention value exceeds the preset judgment threshold, it is determined that the personnel are preparing to enter the danger zone.

[0094] Among them, processor 3 analyzes the hazard sources and determines the hazardous areas, including:

[0095] When the hazard source is a high-voltage power line drop, obtain the line conditions near the intelligent switchgear;

[0096] The voltage corresponding to the hazard source is determined by the shortest distance between the hazard source and each line; the voltage of the line with the shortest distance is the voltage corresponding to the hazard source.

[0097] Consult the voltage-to-hazard range mapping table to determine the extent of the hazardous area. This table is pre-built, and the radius of the hazardous area is correlated with the voltage. By consulting the table, you can determine the radius of the hazardous area corresponding to each voltage, thus defining the extent of the hazardous area.

[0098] The intelligent switchgear protection and control system provided in this embodiment analyzes the second image when no scheduled maintenance or inspection work is received, and then performs corresponding early warnings and emergency operations according to the situation to ensure the personal safety of personnel. In addition, for the second image device, a dual-axis or tri-axis pan-tilt unit is further adopted to further refine the analysis of the external environment, determine whether there are any hazards, monitor the hazards, and ensure that the high-voltage line drop area will not cause harm to personnel, thereby further improving the safety of the power system. Example 3

[0099] In Example 2, the processor 3 analyzes the hazard source and determines the hazardous area. The first step is to determine the voltage. The accuracy of the voltage determination contributes to the accuracy of the hazardous area determination. This example uses the following method instead of the method in Example 2 to achieve a more accurate determination of the hazardous area. The specific steps are as follows:

[0100] An analysis space is constructed based on the wiring conditions around the switchgear;

[0101] Determine the first point in the analysis space corresponding to the grounding point of the high-voltage falling line, and determine at least one first sampling point from the high-voltage falling line, and determine the second point in the analysis space corresponding to the first sampling point;

[0102] Starting from the first point and taking the second point as the direction, determine at least one first vector;

[0103] The line is sampled to obtain multiple second sampling points, and the corresponding third points in the analysis space are determined for the second sampling points.

[0104] Starting from the first point and using the third point as the direction, determine multiple second vectors;

[0105] Calculate the angle between the first vector and the second vector respectively, and take the voltage on the line corresponding to the third point where the angle between the first vector and the second vector is the smallest as the voltage of the hazard source. Example 4

[0106] In Example 2, the processor 3 analyzes the hazard source and determines the hazard area. The first step is to determine the voltage. The accuracy of the voltage determination helps to determine the hazard area accurately. However, on the other hand, in order to ensure safety, the highest voltage of the line near the switch cabinet can be directly used as the voltage of the hazard source. Example 5

[0107] When identifying the hazard of a fallen high-voltage line in Example 2, it is possible to mistakenly identify objects such as tree branches as fallen high-voltage lines. Therefore, a comprehensive analysis based on the line conditions and the inherent properties of the objects can improve the accuracy of the identification. Specific analysis steps include:

[0108] Determine whether the location of the hazard source is within the radiation area corresponding to the circuit of the switchgear, and extract features of the hazard source object;

[0109] The extracted features are input into a preset cable analysis and identification model to determine whether it is a cable.

[0110] The radiation area is associated with the cable distribution and is known. Only the location of the hazard source needs to be determined to assess whether it falls within the designated area. Feature extraction of the hazard source involves extracting features including those representing the object's shape and the width of each segment. The cable analysis and recognition model is pre-trained and converged for cable identification. Example 6

[0111] This embodiment provides an intelligent switchgear protection and control system, such as Figure 2 As shown, it includes: a first image acquisition module 1, a second image acquisition module 2, a processor 3, and a communication module 4; the first image acquisition module 1, the second image acquisition module 2, and the communication module 4 are electrically connected to the processor 3 respectively; in addition, it also includes: multiple temperature and humidity monitoring modules 5;

[0112] The temperature and humidity monitoring module 5 is electrically connected to the processor 3 and is set in a preset position inside the cabinet;

[0113] The processor 3 monitors the temperature and humidity inside the cabinet through the humidity monitoring module 5. When the humidity exceeds the preset first threshold and / or when the temperature exceeds the preset second threshold, the processor 3 controls the power-off of the components associated with the set position of the corresponding temperature and humidity monitoring module.

[0114] The system in this embodiment monitors the temperature and humidity inside the cabinet by installing temperature and humidity monitoring modules at various locations inside the cabinet. Temperature monitoring monitors whether a fire caused by a circuit fault occurs inside the cabinet, and humidity monitoring monitors whether there is leakage inside the cabinet. Power outage alarms are triggered accordingly to ensure safety. Example 7

[0115] This embodiment provides an intelligent switchgear protection and control system, such as Figure 3 As shown, it includes: a first image acquisition module 1, a second image acquisition module 2, a processor 3, and a communication module 4; the first image acquisition module 1, the second image acquisition module 2, and the communication module 4 are electrically connected to the processor 3 respectively; in addition, it also includes: at least one smoke sensor 6;

[0116] When the processor 3 detects smoke inside the cabinet through the smoke sensor 6, it shuts off power to all components.

[0117] The system in this embodiment uses smoke sensors installed inside the intelligent switchgear to monitor and cut off power to the components inside the cabinet when overheating and combustion of wiring occurs, thus cutting off the power source for the heat generated and preventing the combustion from spreading further, ensuring the safety of the switchgear. Specifically, cutting off power to all components can be achieved by configuring an electrical control switch at the incoming line section of the switchgear to disconnect the circuit.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
