[0002] Substations are places in the power system that transform voltage and current, receive and distribute electric energy, and play an indispensable and important role in the power system. Under normal circumstances, substations are usually staffed and need to be inspected at a certain time period. When the substation is abnormal, relevant maintenance personnel need to be arranged to carry out maintenance. Substations are usually large in scale, and different areas of the substation are of different importance to the operation of the substation. Therefore, the on-duty inspection personnel and maintenance personnel have different focuses in different areas.

[0003] At present, there is no differentiated control over the on-duty inspection personnel and maintenance personnel of the substation, which may lead to the intrusion of irrelevant personnel or the intrusion of intentional personnel, and it is also impossible to ensure that the relevant personnel conduct inspections or maintenance according to the standardized procedures, thus affecting the safe operation of the substation. Therefore, how to differentiate and control different types of personnel in the substation is one of the technical problems that need to be solved at present. Summary of the invention

[0047] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0048] The present invention provides a substation personnel management and control method based on a digital twin model. Figure 1 , Figure 1 It is a flow chart of the first embodiment of the substation personnel management and control method based on the digital twin model of the present invention.

[0049] The embodiment of the present invention provides an embodiment of a substation personnel management and control method based on a digital twin model. It should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that here. Specifically, the substation personnel management and control method based on a digital twin model in this embodiment includes:

[0050] Step S10, obtaining the location information of the substation personnel, and mapping the location information to the digital twin model of the substation.

[0051] The substation personnel management and control method based on the digital twin model of this embodiment is applied to a control platform that can be connected to the substation for communication. The substation is equipped with various types of sensors, such as video acquisition devices, infrared devices, ultrasonic devices, cruise robots, cruise drones, positioning devices, etc. This type of sensor monitors various equipment and personnel in the substation. Among them, the positioning information of the substation personnel can be collected through the locations of various sensors, and the positioning information of the substation personnel can also be collected through the positioning device. In addition, a digital twin model is pre-built for the substation, and various sensors transmit the collected positioning information of the substation personnel to the control center, which is mapped to the digital twin model by the control center to reflect the position of each substation personnel in the substation in the digital twin model.

[0052] The digital twin model of the substation is a holographic mapping of the complex physical entity of the substation from the real space to the virtual digital space. It depicts and simulates the real-time status and dynamic characteristics of the substation through the virtual-real connection. Its construction can be carried out based on coordinate transformation. Specifically, the step of obtaining the location information of the substation personnel and mapping the location information to the digital twin model of the substation includes:

[0053] Step a1, acquiring the design model data and physical feature data of the substation, and constructing the design model data and the physical feature data into an initial digital twin model of the substation according to the transformation relationship between the physical coordinate system corresponding to the substation and the preset model coordinate system;

[0054] Step a2: acquiring control sensor data of the substation, and updating the initial digital twin model according to the control sensor data to generate the digital twin model.

[0055] Furthermore, in order to efficiently and comprehensively reflect the physical entity of the substation, when constructing the digital twin model, the design model data and physical feature data of the substation are first obtained. Among them, the design model data is the design scheme when the substation is constructed, and the physical feature data is the actual data when the substation is constructed, that is, the change data relative to the design scheme. Then, according to the correspondence between the physical coordinate system corresponding to the substation and the preset model coordinate system, the design model data and the physical feature data are constructed as the initial digital twin model of the substation. Among them, the physical coordinate system can be a geodetic coordinate system, and the preset model coordinate system is a model coordinate system set for constructing the digital twin model. Through the position difference size of the coordinate origin between the two coordinate systems and the direction difference angle of the coordinate axis, the initial digital twin model of the substation is constructed according to the design model data and the physical feature data. On the one hand, it avoids the problem of huge detection data volume when all physical feature data are obtained by detection to construct the digital twin model, and on the other hand, it makes the constructed digital twin model more accurate by correction through actual physical feature data.

[0056] Furthermore, in order to reflect the control logic of the substation in the digital twin model, the control sensor data of the substation is also acquired, and the initial digital twin model is updated based on the acquired control sensor data to form a digital twin model that includes the physical structure and control logic of the substation.

[0057] Step S20: analyzing the mapped positioning information based on the digital twin model, screening out the personnel to be identified among the substation personnel, and determining the identification type of each of the personnel to be identified.

[0058] Furthermore, from the perspective of substation security, multiple different authority areas can be set for substations. These different authority areas usually correspond to staff members of different authority levels in the substation, and such personnel in the substation need to be subject to regional authority control. Specifically, the divided authority areas have corresponding model area manifestations in the digital twin model, so the mapped positioning information can be analyzed based on the digital twin model to screen out the personnel in the substation who are located at the boundaries of different authority areas and need to enter from one authority area to another, and the screened personnel are identified as personnel to be identified.

[0059] At the same time, inspection personnel and maintenance personnel are identified from the substation personnel. This type of personnel is mainly involved in the management and control of inspection routes and maintenance work. The digital twin model can screen out this type of personnel from the substation personnel by analyzing whether the positioning information carries the identification related to this type of personnel, and determine the screened out personnel as the personnel to be identified. And in order to distinguish and control the two types of personnel, the two are divided into different identification types of personnel to be identified. After the digital twin model analyzes the positioning information to screen out the personnel to be identified among the substation personnel, it determines the identification type of each person to be identified based on the area where the positioning information of the person to be identified is located and the identification carried. Specifically, the steps of analyzing the mapped positioning information based on the digital twin model, screening out the personnel to be identified among the substation personnel, and determining the identification type of each person to be identified include:

[0060] Step b1, determining whether the mapped positioning information is located in the entrance restricted area of ​​the digital twin model; if it is located in the entrance restricted area, determining that the substation personnel is a person to be identified, and the identification type of the person to be identified is authority identification;

[0061] Step b2: if the person is not located in the entrance restricted area, determine whether the positioning information has a corresponding activity identifier; if so, determine that the substation personnel is a person to be identified, and the identification type of the person to be identified is activity identification.

[0062] Furthermore, the different permission areas divided by the substation are provided with corresponding area entrances, and such area entrances form the entry restriction areas in the digital twin model. The positioning information mapped to the digital twin model is compared with such entry restriction areas to determine whether the positioning information is located in any entry restriction area. If it is located in any entry restriction area, the substation personnel from which the positioning information comes is judged as the person to be identified, and the identification type of such person to be identified is determined as permission identification, so as to control the authority of the substation personnel by identifying whether such personnel have the authority to enter the permission area, thereby ensuring the safety of the substation.

[0063] Furthermore, if it is determined that the positioning information is not located in any entrance restricted area, it means that the person to be identified corresponding to the positioning information did not enter from one permission area to another permission area. Continue to identify whether there is a corresponding activity identifier for the positioning information. If there is a corresponding activity identifier, it means that the person to be identified needs to be active in a certain area of ​​the substation. This type of person is also determined to be a person to be identified, and the identification type of this type of person to be identified is determined as activity identification, so as to control the activities of the person to be identified. Among them, the activity identifier corresponding to the positioning information can be uploaded when the person to be identified is identified in the entrance restricted area. That is, when the person to be identified enters the area where he needs to be active from the entrance restricted area, he uploads the activity identifier he needs to engage in when he is identified in the entrance restricted area, so that the positioning information of the person to be identified has a corresponding activity identifier since entering the entrance restricted area.

[0064] Step S30, if the identification type is authority identification, the biometric information of the person to be identified is obtained for identification, a feature identification result is obtained, and the access authority of the person to be identified is controlled based on the feature identification result.

[0065] Furthermore, if it is determined that the identification type of the person to be identified is permission identification, the biometric information of the person to be identified is obtained, and the biometric information can be any one or a combination of fingerprints, palm prints, faces, and irises. After obtaining such biometric information, identification is performed to obtain a feature identification result. The feature identification result indicates whether the person to be identified has access authority, and then the access authority of the person to be identified is controlled based on the feature identification result.

[0066] Step S40, if the identification type is activity identification, the activity trajectory of the person to be identified is obtained for identification, a trajectory identification result is obtained, and the activity standardization of the person to be identified is controlled based on the trajectory identification result.

[0067] Furthermore, if it is determined that the identification type of the person to be identified is activity identification, the activity trajectory of the person to be identified is obtained. The activity trajectory can be the trajectory of the inspection personnel who are the persons to be identified inspecting the substation, or it can be the trajectory of the maintenance personnel who are the persons to be identified performing maintenance in a certain area of ​​the substation. The inspection trajectory and the maintenance trajectory have their own norms. Whether the obtained activity trajectory of this type meets the requirements of this type of norms, the corresponding trajectory identification result is generated. Then, the activity norms of the person to be identified are controlled based on the trajectory identification results.

[0068] The substation personnel control method based on the digital twin model implemented in this embodiment, once the location information of the substation personnel is obtained, the location information is mapped to the digital twin model of the substation; and according to the analysis and processing of the mapped location information by the digital twin model, the personnel to be identified are screened out from the substation personnel, and the identification type of each person to be identified is determined; if the identification type is permission identification, the biometric information of the person to be identified is obtained for identification, and the corresponding feature identification results are obtained to control the access rights of the person to be identified; if the identification type is activity identification, the activity trajectory of the person to be identified is obtained for identification, and the corresponding trajectory identification results are obtained to control the activity norms of the person to be identified. In this way, by constructing the digital twin model of the substation and setting the area where personnel control and identification are required in the digital twin model, the personnel to be identified and their identification types that need to be controlled are determined, and the personnel to be identified are distinguished and identified according to their respective determined identification types. Then, differentiated control is carried out according to the identification results, ensuring the safety of personnel entering the substation, and the maintenance personnel and patrol personnel perform patrol and maintenance according to their respective relevant standard procedures, which is conducive to the safe operation of the substation.

[0069] For further information, please refer to Figure 2 Based on the first embodiment of the substation personnel management and control method based on the digital twin model of the present invention, a second embodiment of the substation personnel management and control method based on the digital twin model of the present invention is proposed.

[0070] The difference between the second embodiment of the substation personnel control method based on the digital twin model and the first embodiment of the substation personnel control method based on the digital twin model is that the activity trajectory includes an operation trajectory, and the step of obtaining the activity trajectory of the person to be identified for identification and obtaining the trajectory identification result includes:

[0071] Step S41, collecting the operation video of the person to be identified based on the video acquisition device of the substation, analyzing and processing the operation video, and extracting key operation information and operation sequence trajectory in the operation video;

[0072] Step S42, generating the key operation information and the operation sequence trajectory as the operation trajectory, identifying the operation trajectory, determining whether there is any safety hazard information in the operation trajectory, and generating the trajectory identification result.

[0073] Furthermore, for the maintenance personnel who are to be identified, their maintenance activity trajectory is essentially the maintenance operation of the maintenance personnel, which can be used as the operation trajectory. Specifically, the operation video of the person to be identified is collected by the video acquisition device of the substation, and the operation video is analyzed, and multiple video frames are extracted from the operation video at a certain time interval. Then, according to the time sequence of each video frame in the operation video, each video frame is identified to obtain the operation sequence trajectory of the maintenance performed by the person to be identified. At the same time, different equipment has different performances, and their respective maintenance methods and maintenance steps are also different. In order to ensure the correctness of the key maintenance steps, key step information is pre-set for each equipment. For the collected operation video, first identify the equipment corresponding to the operation video, then find the key step information corresponding to the equipment, and then identify the extracted video frame based on the key step information to obtain the key operation information.

[0074] Furthermore, the key operation information and the operation sequence trajectory are obtained to form an operation trajectory, and the operation trajectory is identified to determine whether there are safety hazards in the operation trajectory. Among them, the safety hazard reflects that the maintenance operation of the person to be identified is inconsistent with the standardized maintenance operation. For each device of the substation, in addition to the key step information pre-set, an operation specification trajectory is also set, and the key operation information in the operation trajectory is compared with the key step information to determine whether the extracted key operation information matches the key step information, and the operation sequence trajectory in the operation trajectory is compared with the operation specification trajectory to determine whether the generated operation sequence trajectory is consistent with the operation specification trajectory. If the key operation information matches the key step information, and the operation sequence trajectory matches the operation specification trajectory, it means that the maintenance operation of the person to be identified is standardized, and the generated trajectory recognition result is no safety hazard. On the contrary, if the key operation information does not match the key step information, or the operation sequence trajectory does not match the operation specification trajectory, it means that the maintenance operation of the person to be identified is not standardized, and the generated trajectory recognition result is that there is a safety hazard.

[0075] Understandably, for trajectory recognition results without safety hazards, only records can be made without other control processing, but for trajectory recognition results with safety hazards, prompt information is output to prompt the person to be identified to perform maintenance in accordance with standardized operations so as to control the maintenance operations of the person to be identified.

[0076] For the patrol personnel who are the persons to be identified, their patrol activity trajectory is actually the patrol route of the patrol personnel, and this type of activity trajectory is the patrol trajectory. For this type of patrol trajectory, the step of obtaining the activity trajectory of the person to be identified for identification and obtaining the trajectory identification result includes:

[0077] Step S43, tracking the inspection trajectory of the person to be identified based on the trajectory tracking device of the substation, and mapping the inspection trajectory to the digital twin model;

[0078] Step S44: Identify the correctness of the inspection trajectory based on the reference inspection trajectory in the digital twin model to obtain the trajectory identification result.

[0079] Furthermore, there are many devices in the substation, and different devices require different inspection cycles. If unified inspections are performed according to the longest cycle, the devices with short cycles may fail. If unified inspections are performed according to the shortest cycle, the inspections may be too frequent, increasing the cost of the inspections. Therefore, in order to balance, devices with close cycles can be set for unified inspections, so that not all devices need to be inspected in one inspection. At the same time, in order to achieve efficient inspections, the inspection route can be set according to the location of the equipment to be inspected, and inspections can be performed sequentially along the route to avoid returning back and forth and reducing the inspection efficiency. The set inspection route is pre-mapped to the digital twin model as a reference inspection trajectory.

[0080] Furthermore, for the patrol personnel who are to be identified, their positions can be located in real time through the trajectory tracking device of the substation, and then the various positions at different times are formed into the patrol trajectory of the person to be identified, and the formed patrol trajectory is mapped to the digital twin model. The mapped patrol trajectory is identified according to the reference patrol trajectory pre-generated by the digital twin model, and the similarity between the two is determined. If the similarity between the two is higher than the set value after identification, it means that the overlap between the two is high, the patrol trajectory of the person to be identified is correct, and a correct patrol trajectory identification result is generated. On the contrary, if the similarity between the two is lower than the set value after identification, it means that the overlap between the two is low, the patrol trajectory of the person to be identified is incorrect, and a certain device may be missed, generating an incorrect patrol trajectory identification result.

[0081] Furthermore, for the correct inspection trajectory recognition results, only records can be made without any other control processing, but for the incorrect inspection trajectory recognition results, prompt information is output to prompt the personnel to be identified to perform inspections according to the reference inspection trajectory so as to control the inspection route of the personnel to be identified.

[0082] This embodiment generates operation trajectories and inspection trajectories for identification of maintenance personnel and inspection personnel in the substation, and obtains corresponding identification results, which are used to manage the standardization of the activities of the identified personnel, ensure the standardization of the maintenance personnel, avoid safety hazards, and ensure the correctness of the inspection routes of the inspection personnel to avoid missing equipment that needs to be inspected, which is conducive to ensuring the safe operation of the substation.

[0083] For further information, please refer to Figure 3Based on the first and second embodiments of the substation personnel management and control method based on the digital twin model of the present invention, a third embodiment of the substation personnel management and control method based on the digital twin model of the present invention is proposed.

[0084] The third embodiment of the substation personnel management and control method based on the digital twin model is different from the first and second embodiments of the substation personnel management and control method based on the digital twin model in that the step of obtaining the biometric information of the person to be identified for identification and obtaining the feature identification result includes:

[0085] Step S31, collecting a biometric image of the person to be identified based on the biometric information collection device of the substation, and extracting biometric information from the biometric image;

[0086] Step S32, comparing the biometric information with various reference features in a biometric reference library, and identifying whether there is a target reference feature matching the biometric information among the various reference features;

[0087] Step S33, if the target reference feature exists, generating a feature recognition result that passes the authority recognition;

[0088] Step S34: if the target reference feature does not exist, a feature recognition result indicating that the authority recognition fails is generated.

[0089] Furthermore, for personnel control in the restricted entrance area, the biometric image of the person to be identified is collected by the biometric information collection device of the substation, which can be any one of a face image, a fingerprint image, a palm print image and an iris image. Then, the collected biometric image is processed to extract the biometric information from the biometric image. At the same time, a biometric reference library is pre-set, and the biometric information of the persons with access rights is collected and stored in the biometric reference library as a reference feature. The extracted biometric information is compared with each reference feature in the biometric reference library to determine whether there is a target reference feature that matches the biometric information in each reference feature. Among them, whether it matches or not can be determined by setting a similarity threshold. If the similarity value between the identified biometric information and the reference feature is greater than the similarity threshold, it means that the similarity between the two is high and the two are determined to match. Otherwise, the two are not matched.

[0090] Furthermore, for the presence of biometric information that matches the target reference feature, it means that the person to be identified corresponding to the biometric information is a person with access authority, so a feature recognition result of permission recognition is generated. On the contrary, if there is no target reference feature that matches the biometric information, it means that the person to be identified does not have access authority, and the generated feature recognition result is permission recognition failure, so as to prevent people who do not have access authority from entering the substation. After the feature recognition result is generated, the access authority of the person to be identified can be controlled based on it. Specifically, the step of controlling the access authority of the person to be identified based on the feature recognition result includes:

[0091] Step S35, if the feature recognition result is that the authority recognition is passed, the image acquisition device based on the substation collects the clothing image of the person to be identified, and identifies whether the clothing image matches the standard clothing image;

[0092] Step S36, if the image matches the standard dress image, the access permission of the person to be identified is determined as allowed entry; if the image does not match the standard dress image, the access permission of the person to be identified is determined as prohibited entry;

[0093] Step S37: If the feature recognition result is that the authority recognition fails, the entry and exit authority of the person to be identified is determined as prohibited entry.

[0094] Furthermore, for the feature recognition result of the authority recognition passing, the person to be identified has the need to enter the substation. In order to ensure the safety of the person to be identified, there are usually certain requirements for the clothing of the person to be identified, such as wearing a helmet or wearing specific radiation-proof clothing. Therefore, if the feature recognition result is that the authority recognition is passed, the image of the clothing of the person to be identified is collected by the image acquisition device of the substation. In addition, a standard dress image representing standard dress is pre-set, and the collected dress image is compared with the standard dress image to determine whether the dress image matches the standard dress image. Among them, whether the match includes at least two aspects, one is whether the dress of the person to be identified has the various dress contents required by the standard dress, and the other is whether the various dress contents have met the standard requirements of the standard dress. After the dress in the dress image is determined to match the dress content and standard requirements reflected in the standard dress image through identification, it can be determined that the two match, otherwise only one of them does not match, it is determined that the two do not match.

[0095] Furthermore, if the dress image matches the standard dress image, the access permission of the person to be identified is determined as allowed entry, that is, the person to be identified is allowed to enter the substation. If the dress image does not match the standard dress image, the access permission of the person to be identified is determined as prohibited entry, that is, the person to be identified is prohibited from entering the substation. At the same time, a prompt message can be output for the unmatched person to be identified to prompt the person to be identified to enter the substation after dressing in accordance with the standard.

[0096] In addition, for the feature recognition results that fail the authority recognition, the access authority of the person to be recognized is directly determined as prohibited entry. This avoids the risks that may be brought to the substation by people who do not have the authority to enter the substation, and the risks that the substation may bring to such people.

[0097] This embodiment controls the entry and exit rights of personnel in the restricted entrance area by combining biometric images and dress code. Only those who have passed the biometric image and dress code can enter the substation, which is conducive to ensuring the safety of the substation and the personnel to be identified.

[0098] For further information, please refer to Figure 4 Based on the first, second and third embodiments of the substation personnel management and control method based on the digital twin model of the present invention, a fourth embodiment of the substation personnel management and control method based on the digital twin model of the present invention is proposed.

[0099] The fourth embodiment of the substation personnel control method based on the digital twin model is different from the first, second and third embodiments of the substation personnel control method based on the digital twin model in that the step of mapping the positioning information to the digital twin model of the substation includes:

[0100] Step S50, determining whether the positioning information is mapped in each guard area of ​​the digital twin model;

[0101] Step S60, if there is a target guard area in each of the guard areas to which the positioning information is not mapped, the target guard area is marked as an absent guard area;

[0102] Step S70, after a preset period, determining whether there is updated positioning information for the absent duty area, and if there is updated positioning information, removing the identification of the absent duty area;

[0103] Step S80: if there is no updated positioning information, the absent duty area is generated as warning information.

[0104] Furthermore, in addition to access rights and activity control, the control of substation personnel also involves on-duty control of personnel. Specifically, a duty area can be set for important areas of the substation, and the set duty area can be mapped to the digital twin model. After mapping the positioning information to the digital twin model, it is determined whether the positioning information is mapped in each duty area of ​​the digital twin model. If the positioning information is mapped, it means that the duty areas of the substation are all staffed. On the contrary, if it is determined that there is a duty area in each duty area that does not map the relevant positioning information, it means that the duty area does not have staff on duty. At this time, the duty area is determined as the target duty area among the duty areas, and an identification is added to form an absent duty area.

[0105] Furthermore, the person who may be responsible for guarding the absent guard area may just temporarily leave the guard area, so a preset interval period is set, and timing is performed after the mark. When the timing time reaches the preset interval period, it is determined whether there is a person on duty in the absent guard area, so as to judge whether there is updated positioning information in the absent guard area. If it is determined that there is a person on duty in the absent guard area, it means that there is updated positioning information in the absent guard area, otherwise it means that there is no updated positioning information in the absent guard area.

[0106] Furthermore, for the absent duty area with updated positioning information, it means that there are corresponding duty personnel in the absent duty area, so the identification of the absent duty area is removed and restored to the original normal duty area. On the contrary, if it is determined that there is still no updated positioning information, it means that the absent duty area is still unattended. At this time, the absent duty area is generated as a warning message to remind that there is no relevant personnel on duty in the absent duty area, and relevant personnel need to be dispatched to guard to ensure the safety of the area.

[0107] This embodiment sets up a personnel on-duty control mechanism for important areas of the substation, so that each important area that requires personnel on duty has relevant personnel on duty, which is conducive to further ensuring the safety of the substation.

[0108] In addition, the embodiment of the present invention also provides a substation personnel management and control system based on the digital twin model.

[0126] If the target reference feature exists, generating a feature recognition result that passes the authority recognition;

[0128] Furthermore, the step of controlling the access rights of the person to be identified according to the feature recognition result includes:
