[0002] Substations are an important part of the power system. The smooth operation of substations is related to social stability and people's normal life. Substations contain high-voltage equipment, which will generate strong electric and magnetic fields during operation, posing serious safety risks such as electric shock and electric shock. People who stray into the substation may accidentally touch the equipment, causing damage or failure, affecting the normal operation of the substation, and may even cause large-scale power supply interruptions.

[0003] Existing technical means use warning signs, electronic fences, access control systems, etc. to alert people to mistaken entry, but most of the faulty equipment in the substation requires on-site maintenance by construction personnel; due to the complex substation maintenance site environment, the equipment carries high voltage and strong electricity, the risk factor is high, and there are many safety hazards. It is inevitable that construction personnel performing on-site maintenance may mistakenly enter the energized area of ​​the substation due to negligence at work.

[0004] In the prior art, the operation information of the live area is usually used to determine whether the personnel in the live area have entered by mistake or are working. It is impossible to accurately identify whether the personnel in the substation are workers in the live area or people who have entered by mistake, which is prone to misjudgment and random alarms. It still takes manpower to distinguish. At the same time, the operation information of each substation obtained by manpower has a certain lag, and the identification may not be accurate.

[0029] In this embodiment, a monitoring method for a substation running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0030] Figure 2 1 is a flow chart of a monitoring method for a substation according to an embodiment of the present application. The monitoring method is applied to a substation monitoring system, which includes a data module, an image acquisition module, a modeling module, a positioning module, an alarm module and a processor module. Figure 2 As shown, the method comprises the following steps:

[0031] Step 201, obtaining environmental information and historical operation information of the substation, and visually modeling the substation through a modeling module to construct a 3D model to obtain a target model, wherein the target model includes a non-energized area, a fixed energized area, and a variable energized area;

[0032] Specifically, the model module is used to establish a corresponding 3D visualization model of the substation based on the substation environmental information, and divide the substation 3D visualization model into energized areas and non-energized areas based on historical information. The energized areas include fixed energized areas and variable energized areas, and safety distances are divided for fixed energized areas and variable energized areas according to the surrounding environment.

[0033] Step 202: Real-time monitoring of the staff in the substation is performed through the image acquisition module to obtain a first target image, and the estimated direction of travel and the staff's wearing information are determined based on the first target image;

[0034] Specifically, the image acquisition module includes multiple monitors, and multiple monitors are set up in various areas of the substation for real-time monitoring of the substation for image acquisition and monitoring the entry and exit of personnel. The wearing information of the workers entering the fixed live areas and variable live areas includes personal protective equipment (work clothes, safety helmets, insulating gloves, protective glasses, terminals, etc. The work clothes of the workers are inconsistent with those of other personnel. The terminal includes a positioning function to facilitate the system to monitor the location information of the workers in real time).

[0035] Step 203, collecting real-time operation data of the substation through the data module, and collecting real-time operation information of each area in the substation through the work ticket;

[0036] Specifically, the data module includes a data acquisition unit and a data extraction unit; the data acquisition unit is used to obtain external data, including the wear information data of the operators, the operation data of each device in the substation, and the real-time operation information of each area obtained through the work ticket; the data extraction unit is used to extract relevant data from the image collected by the monitoring module, including the wear information data of the personnel in the current image. According to the operation information of the relevant area corresponding to the work ticket collected by the data module, the operators are further confirmed to prevent the operators from mistakenly entering other areas where they do not need to work.

[0037] Step 204, obtaining the real-time position of the staff in the substation through the positioning module to obtain first position information;

[0038] Specifically, the AI ​​positioning module is used to obtain the specific location information of all personnel in the current substation through the real-time monitoring information of the monitoring module combined with the 3D visualization model of the model module.

[0039] Step 205, the processor predicts the movement of the staff based on the first position information and the expected travel direction, obtains the target travel trajectory, determines the target area type based on the first position information and the target model, and identifies the staff's authority based on the target area type, the target travel trajectory, the personnel's wearing information, the real-time operation information and the first target image. If the authority identification fails, an alarm is issued through the alarm module.

[0040] Specifically, the alarm module includes a plurality of alarms, and the plurality of alarms respectively receive instructions sent by the processor to respond.

[0041] It can be seen that the processor is interconnected with the model module, monitoring module, data module, positioning module, and alarm module respectively, and is used to receive data information interaction and issue instructions between each module. By comprehensively applying location information, expected travel direction, target model, personnel wear information and real-time operation information, the system can accurately predict the movement of staff and identify permissions. This method not only improves the safety and management efficiency of the construction site, but also promotes the intelligent and standardized development of safety management through data recording and processing. The timely triggering of the alarm module also ensures a quick response in the event of failure of permission identification to ensure site safety.

[0042] The embodiment of the present application provides a monitoring method for a substation, which first obtains environmental information and historical operation information of the substation, and visually models the substation through a modeling module to construct a 3D model to obtain a target model, wherein the target model includes a non-energized area, a fixed energized area, and a variable energized area; then, the staff in the substation are monitored in real time through an image acquisition module to obtain a first target image, and the expected travel direction and wear information of the staff are determined based on the first target image; then, the real-time operation data of the substation is collected through a data module, and the real-time operation information of each area in the substation is collected through a work ticket; secondly, the real-time position of the staff in the substation is obtained through a positioning module to obtain the first position information; finally, the movement of the staff is predicted by a processor based on the first position information and the expected travel direction to obtain the target travel trajectory, the target area type is determined based on the first position information and the target model, and the authority of the staff is identified based on the target area type, the target travel trajectory, the wear information of the staff, the real-time operation information, and the first target image. If the authority identification fails, an alarm is issued through an alarm module. The present application monitors the movement of personnel in real time through surveillance images, and combines the operation information of each area of ​​the substation to determine whether the operating personnel in each area at the current moment meet the operation requirements, and then issues an alarm if they do not meet the requirements, thereby realizing real-time monitoring of the movement of staff, avoiding the accidental entry of non-operating personnel or the failure of staff to wear equipment that meets safety regulations, and solving the problem in the prior art of preventing accidental entry of personnel through means such as warning signs, electronic fences and access control, and being unable to identify whether there are safety hazards in the safety equipment of staff.

[0043] As a possible implementation method, the substation area is monitored in real time, and the personnel appearing in the substation area are identified, and the authority of the corresponding personnel is restricted according to the corresponding identification results. The authority identification of the staff is performed based on the target area type, the target movement trajectory, the personnel wearing information, the real-time operation information and the first target image, including:

[0044] When the target area type is a non-powered area, recognition is performed based on the first target image to divide the workers into operating personnel and non-operating personnel;

[0045] Specifically, the personnel in the non-electrical area are divided into non-operating personnel and operating personnel in the fixed and variable electrified areas according to their wearing information. The system also includes an identification module, which classifies operating personnel whose clothing does not meet safety standards into non-operating personnel to avoid accidents caused by entering the electrified area due to wearing clothing that does not meet safety standards.

[0046] When the worker is a non-operating personnel and the target moving trajectory passes through a fixed live area or a variable live area, if the distance between the non-operating personnel and the fixed live area or the variable live area is less than the preset safety distance, it is determined that the authority identification fails.

[0047] It can be seen that in the substation monitoring system, authority identification is a key link to ensure the safety of staff. The system also includes an identification module, which is used to compare the wearing information data of the personnel in the current image with the wearing data of the set operating personnel that meets the safety standards obtained by the data acquisition unit to determine whether the personnel in the current monitoring module are operating personnel; the identification module can use convolutional neural networks and target detection algorithms for identification. The system strictly identifies the authority of the staff by comprehensively analyzing the target area type, target travel trajectory, personnel wearing information, real-time operation information and the first target image.

[0048] As a possible implementation method, the authorization identification of the staff is performed based on the target area type, the target travel trajectory, the personnel wearing information, the real-time operation information and the first target image, and the following steps are also included:

[0049] Step S301, when the staff is an operator, the real-time operation information shows that both the variable electrified area and the fixed electrified area have operation requirements, and the personnel wear information safety specification detection passes, it is determined that the authority identification passes;

[0050] Specifically, based on the operation information of the fixed live area and the variable live area, it is determined whether the operating personnel are currently required to enter the fixed live area or the variable live area to perform operations; if there are operation requirements in the fixed live area and the variable live area, no alarm will be issued when the operating personnel approach the fixed live area and the variable live area, and the authority identification is passed.

[0051] Step S302, when the staff member is an operator, the real-time operation information indicates that there is an operation demand in the variable live area, there is no operation demand in the fixed live area, the personnel wear information safety specification detection passes, and the target moving trajectory passes through the fixed live area, if the distance between the operator and the fixed live area is less than the preset safety distance, it is determined that the authority identification fails;

[0052] Specifically, if there is an operation demand in the variable live area but not in the fixed live area, no alarm will be issued when the operator approaches the variable live area, but once the operator enters the minimum safe distance of the fixed live area, an alarm will be issued immediately.

[0053] Step S303, when the worker is an operator, the real-time operation information shows that there is no operation demand in the variable live area, there is an operation demand in the fixed live area, the personnel wear information safety specification detection passes, and the target moving trajectory passes through the variable live area, if the distance between the operator and the variable live area is less than the preset safety distance, it is determined that the authority identification fails;

[0054] Specifically, if there is an operation demand in the fixed live area but there is no operation demand in the variable live area, no alarm will be issued when the operator approaches the fixed live area, but once the operator enters the minimum safe distance of the variable live area, an alarm will be issued immediately.

[0055] Step S304, when the staff is an operating personnel, the real-time operating information shows that there is no operating demand for both the variable electrified area and the fixed electrified area, and the personnel wearing information safety specification detection passes, it is determined that the authority identification fails.

[0056] Specifically, if there is no work demand in the fixed live area and the variable live area, an alarm will be immediately issued once the operator enters the minimum safe distance of the fixed live area or the variable live area.

[0057] As a possible implementation method, the authority identification of the staff is performed based on the target area type, the target travel trajectory, the personnel wearing information, the real-time operation information and the first target image, and further includes:

[0058] In the case where the worker is an operating worker, the personnel wear information safety specification detection fails, and the target travel trajectory passes through a fixed charged area and / or a variable charged area, it is determined that the authority identification fails.

[0059] Specifically, the operator's wearing information is identified based on the current monitored live area. If it meets the safety requirements, no alarm is issued; if the operator's wearing information does not meet the safety requirements, it is determined to be a non-operating personnel and an alarm is issued.

[0060] As a possible implementation method, the authority of the staff is identified based on the target area type, the target travel trajectory, the personnel wearing information, the real-time operation information and the first target image, including:

[0061] Based on the first target image, the workers are identified and divided into operating workers and non-operating workers;

[0062] Specifically, the personnel in the non-electrical area are divided into non-operating personnel and operating personnel in the fixed electrified area and the variable electrified area according to the wearing information of the personnel in the non-electrical area.

[0063] In the case where the target area type is a fixed live area, if the real-time operation information shows that there is an operation demand in the fixed live area and the personnel wear information safety specification detection passes, it is determined that the permission identification passes;

[0064] Specifically, the operation information of the current fixed energized area is obtained according to the work ticket. If there is an operation requirement, it is identified based on the wearing information of the personnel currently monitoring the fixed energized area. If it meets the safety requirements, no alarm is issued.

[0065] When the target area type is a fixed energized area, if the real-time operation information shows that there is no operation demand in the fixed energized area and / or the personnel wearing information safety specification detection fails, it is determined that the authority identification fails.

[0066] Specifically, if the current person's wearing information does not meet safety requirements, he or she will be judged as a non-operating person, an alarm will be issued, and the guidance route information will be issued on the corresponding display screen; if there is no operating information in the current fixed live area, an alarm will be issued if a person appears in the fixed live area.

[0067] As a possible implementation method, the authority of the staff is identified based on the target area type, the target travel trajectory, the personnel wearing information, the real-time operation information and the first target image, including:

[0068] In the case where the target area type is a variable live area, if the real-time operation information shows that there is an operation demand in the variable live area and the personnel wear information safety specification detection passes, it is determined that the authority identification passes;

[0069] Specifically, the operation information of the current variable live area is obtained according to the work ticket; if there is an operation requirement, it is identified based on the personnel wearing information in the currently monitored variable live area. If it meets the safety requirements, no alarm is issued.

[0070] When the target area type is a variable electrified area, if the real-time operation information shows that there is no operation demand in the variable electrified area and / or the personnel wearing information safety specification detection fails, it is determined that the authority identification fails.

[0071] Specifically, if the safety requirements are not met, an alarm is issued and the corresponding display screen issues guidance route information; if there is no operation information in the current variable live area, an alarm is issued if personnel appear in the variable live area.

[0072] As a possible implementation, the substation monitoring system further includes a trajectory generation module and a display module. After determining that the authority identification fails, the method further includes:

[0073] A target trajectory is generated by a trajectory generation module based on the first position information, the target trajectory and the target model, wherein the target trajectory is a trajectory starting from the first position information, ending at the non-charged area and not passing through the fixed charged area and the variable charged area;

[0074] Specifically, the trajectory generation module is used to generate the best escape path based on the specific location information of the personnel who have mistakenly entered the fixed live area and the variable live area obtained from the AI ​​positioning module and the recognition module, combined with the 3D visualization model of the substation in the model module, to ensure the safety of the personnel, and send the best escape path information to the processor; the path generation module can use the RRT algorithm to generate the path.

[0075] The target trajectory is visualized through the display module.

[0076] Specifically, the display module includes multiple display screens, which are arranged in various areas of the substation.
