[0030] In this embodiment, a control method for a substation electronic safety fence 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.

[0031] Figure 3 1 is a flow chart of a control method for a substation electronic safety fence according to an embodiment of the present application. Figure 3 As shown, the method comprises the following steps:

[0032] Step S301, obtaining work ticket information, extracting coordinate data of the operation construction point according to the work ticket information, and obtaining a first target position;

[0033] Specifically, the work ticket information currently in progress is obtained from the substation management system or related equipment, and the specific coordinate data of the work construction point is extracted from the work ticket information. These data are usually recorded in safety-related documents or systems. Based on the extracted coordinate data, the specific location of the work construction point, that is, the first target location, is determined.

[0034] Step S302, determining a setting area of ​​the electronic fence based on the first target position and the preset safety distance, and obtaining a plurality of second target positions;

[0035] Specifically, according to the safety specifications and operation type of the substation, a safety distance is preset (for example, 5 meters around the operation point). Based on the first target position and the preset safety distance, the area that the electronic fence needs to cover is calculated. According to the calculated area, the specific positions of the electronic fence support columns are determined, and multiple second target positions are generated.

[0036] Step S303, controlling the movement of the electronic fence support poles according to the second target position until each electronic fence support pole reaches the corresponding second target position;

[0037] Specifically, confirm the current position of each electronic fence support post, and control the electronic fence support post to move to the corresponding position according to the second target position determined in step S302. During the movement, the position of the support post is monitored in real time through sensors or positioning systems to ensure that they accurately reach the second target position.

[0038] Step S304, activating the infrared emitting device of each electronic fence support column to realize real-time monitoring of the entry and exit of operators.

[0039] Specifically, when all the electronic fence support posts have reached the corresponding second target position, the infrared radiation device on each support post is activated. The infrared radiation device starts to work and monitors the operation area in real time to prevent unauthorized personnel from entering or operators from leaving the designated area. If an abnormal entry or exit is detected, the alarm system is triggered to notify relevant personnel to handle it.

[0040] In summary, obtaining the coordinates of the construction site through the work ticket information ensures that the workers are working in a legal and safe area, which helps to avoid unauthorized operations. According to the obtained coordinate information of the construction site and the set safety distance, the electronic fence can accurately enclose the work area to reduce the chance of accidents. The activated infrared counter-radiation device can monitor the entry and exit of personnel in real time, detect abnormal behavior in time, and reduce safety hazards. The entire process from obtaining the work ticket to setting up the electronic fence forms a traceable management system, which improves the standardization of management.

[0041] As an optional method, determining the setting area of ​​the electronic fence based on the first target position and the preset safety distance to obtain multiple second target positions includes the following steps:

[0042] Step S401, when the distance between the first target positions corresponding to the work ticket information is greater than or equal to twice the preset safety distance, the corresponding second target positions are determined with the first target positions as the center, and the distance between the boundary of the first target position and the boundary of the corresponding second target position is greater than or equal to the preset safety distance;

[0043] Specifically, the location information of each specific operation is obtained from the relevant work ticket, including the operation type, location coordinates, etc. The area where the current operation is actually performed, that is, the first target location, is determined based on the operation information. The actual distance between each first target location is calculated using geographic coordinates or other location recognition technology, and compared with the preset safety distance to confirm whether there is a potential safety hazard. If the distance between each first target location is greater than or equal to twice the preset safety distance, it indicates that these operation areas can be carried out safely and independently.

[0044] It can be seen that, with each first target position as the center, a corresponding second target position is established to ensure that the distance between the boundary of each first target position and the boundary of the corresponding second target position is greater than or equal to the preset safety distance.

[0045] Step S402, when the distance between the first target positions corresponding to each work ticket information is less than twice the preset safety distance, merge the first target positions to obtain at least one third target position, and determine the corresponding second target position with the third target position as the center, and the distance between the boundary of the third target position and the corresponding second target position is greater than or equal to the preset safety distance.

[0046] Specifically, if the distance between any two first target positions is less than twice the preset safety distance, it means that there is a risk of mutual interference in their working areas. All first target positions that meet the merging conditions will be merged to form at least one new working area, namely the third target position. The newly determined third target position and its corresponding second target position will be marked on the spot, and obvious warning signs and visual identification can be used to remind operators to pay attention to the safety area.

[0047] In summary, through the above process, the work ticket information of the construction site can be effectively integrated, the operation area can be reasonably planned, and sufficient safety distance can be ensured, thereby improving the safety management level of the construction site. This method not only helps to ensure the safety of the workers, but also improves the construction efficiency and is conducive to the optimization of the overall project management.

[0048] As an optional manner, after determining the setting area of ​​the electronic fence based on the first target position and the preset safety distance to obtain multiple second target positions, the method further includes the following steps:

[0049] Step S501, when the distance between the first target positions corresponding to the work ticket information is greater than or equal to twice the preset safety distance, obtain the work content, and set the entrance and exit of the workers in the second target position based on the work content, to obtain at least one third target position, and the second target position includes the third target position;

[0050] Specifically, with the first target position as the center, the second target position is set based on the preset safety distance to ensure safe isolation between working areas, and it is verified whether the distance between each first target position is greater than or equal to twice the preset safety distance to ensure the effectiveness of the safety area. The entrance and exit of the workers are planned in each second target position to ensure that its location is convenient for operation and does not interfere with other operations.

[0051] When the distance between the first target positions corresponding to each work ticket information is less than twice the preset safety distance, the adjacent distance between the boundaries of each first target position is intercepted at the position corresponding to the second target position, and determined as the entrance and exit corresponding to the first target position, to obtain at least one third target position.

[0052] In summary, by deeply analyzing the adjacent distances of the boundaries of the work area, carefully intercepting the entrances and exits, and forming a reasonable third target position, the safety and work efficiency of the construction site can be significantly improved. This approach not only helps to ensure the safety of the workers, but also optimizes the space utilization and management layout, providing a solid foundation for the smooth progress of the project.

[0053] As an optional method, the electronic fence support column also includes an infrared receiving unit, a camera and an alarm unit, and the infrared shooting device of each electronic fence support column is activated to realize real-time monitoring of the entry and exit of the operator, including:

[0054] Step S601, when the electronic fence support column is at the second target position and at the third target position, the infrared emitting device of each electronic fence support column is controlled to emit infrared rays to the electronic fence support columns on both sides, and the infrared receiving unit of each electronic fence support column is controlled to receive the light signal emitted by the electronic fence support column on the opposite side. When the infrared receiving unit does not receive the light signal, the camera is controlled to perform portrait tracking to collect image data, and a first alarm message is issued, where the first alarm message is used to indicate the existence of illegal intrusion into the construction area;

[0055] Specifically, when the electronic fence support column is in the second target position and in the third target position, that is, when the above-mentioned electronic fence support column is in the fence area, the infrared shooting device is used to monitor in real time whether anyone illegally breaks into the construction area. When the infrared rays are blocked, the camera is used to detect the intruder and an alarm is issued.

[0056] When the electronic fence support column is in the third target position, the infrared radiation device of each electronic fence support column is controlled to emit infrared rays to the electronic fence support columns on both sides, and the infrared receiving unit of each electronic fence support column is controlled to receive the light signal emitted by the electronic fence support column on the opposite side. When the infrared receiving unit does not receive the light signal, the operator information and safety measures information are extracted from the work ticket information, and the camera is controlled to perform portrait tracking to collect image data, and authority authentication is performed based on the image data and the operator information. If the authority authentication fails, a first alarm message is issued. If the authority authentication passes, a safety specification detection is performed based on the image data and the safety measures information. If the safety specification detection fails, a second alarm message is issued. The second alarm message is used to indicate that the operator's safety specification detection has failed.

[0057] Specifically, when the electronic fence support column is in the third target position, that is, when the above-mentioned electronic fence support column is used to detect entrances and exits, an infrared shooting device is used to detect whether someone passes by. When a person entering is detected, facial data is collected by a camera for identity matching to prevent non-staff from entering. If the match fails, an illegal intrusion alarm is issued. If the identity match passes, further detection is performed based on the image data to ensure that the staff's safety measures are qualified. If the safety measures are unqualified, an alarm is issued to prompt the staff to sort out.

[0058] In summary, through the comprehensive application of electronic fence support columns, infrared beam devices, cameras, and work ticket information, it is possible to achieve strict monitoring of the authority authentication and safety regulations of operators at the construction site. This not only improves the safety of the construction area, but also strengthens the management and responsibility of personnel, providing a strong guarantee for achieving a safe and efficient construction environment.

[0059] As an optional manner, after controlling the camera to perform portrait tracking to collect image data and issue a first alarm message, the method further includes:

[0060] The operator is extracted from the work ticket information, and the authority authentication is performed based on the image data and the operator information. If the authority authentication is passed, a third alarm message is issued. The third alarm message is used to indicate that the operator has not entered according to the prescribed entrance and exit.

[0061] When illegal entry of a person is detected in the fenced area, identity matching is performed. If the match is successful, it is determined that the staff has entered the non-standard location and the alarm level will be increased.

[0062] It can be seen that by combining work ticket information, image data and authority authentication, and implementing a strict entrance and exit management process, it is possible to effectively ensure that workers enter and exit according to the prescribed entrances and exits, and promptly detect and deal with violations. This method not only improves the safety of the construction site, but also improves the overall safety management level through detailed records and rapid response, providing a strong guarantee for achieving a safe and efficient construction environment.

[0063] As an optional method, controlling the camera to perform portrait tracking to collect image data, and performing authority authentication based on the image data and operator information includes the following steps:

[0064] Step 601, obtaining a real-time video stream of a camera, and determining a region corresponding to a human portrait in the real-time video stream based on moving target monitoring, to obtain first image data;

[0065] Specifically, real-time video stream data is obtained from surveillance cameras installed at the main entrances and exits of the construction site. Moving target detection algorithms (such as optical flow method and background difference method) are used to determine moving objects in the video stream, mainly focusing on detecting the portrait area. The area containing the portrait is extracted to form the first image data for subsequent face detection.

[0066] Step 602, performing face detection based on the first image data by using a background subtraction method modeled by a Gaussian mixture model, extracting an area corresponding to the face in the portrait area, and obtaining second image data;

[0067] Specifically, a Gaussian mixture model (GMM) is used to model the background, and background subtraction is used to distinguish the foreground (portrait) from the background. The face area in the first image data is detected, and the face position is accurately determined using face recognition technology (such as Haar features and HOG features). The second image data is extracted, containing the accurate face area, for subsequent feature extraction.

[0068] Step 603, performing preprocessing based on the second image data and extracting features through a convolutional neural network to obtain a target feature value, wherein the preprocessing at least includes grayscale conversion, face registration, data enhancement, and image filtering;

[0069] Specifically, a pre-trained convolutional neural network (such as ResNet and VGGNet) is used to perform deep feature extraction on the preprocessed image to obtain the target feature value.

[0070] Step 604, determining the face identity information by matching in a preset face database based on the target feature value, and matching the face identity information with the operator information, wherein the preset face database includes the face data and corresponding identity information of all operators;

[0071] Specifically, the target feature value is compared with the feature value in the face database, the face identity information is determined by similarity calculation, and the identified identity information is matched with the extracted operator information to confirm whether it is an authorized person.

[0072] Step 605, when the facial identity information and the operator information match, it is determined that the permission authentication is passed; when the facial identity information and the operator information do not match, it is determined that the permission authentication is failed.

[0073] Specifically, if the facial identity information matches the operator information successfully, it is determined that the permission authentication is passed, and the person is allowed to enter or operate. If the match fails, it is determined that the permission authentication is not passed, an alarm message is issued, and unauthorized personnel are denied entry or operation.

[0074] In summary, by combining cameras, face recognition, convolutional neural networks and face databases, refined and intelligent real-time monitoring and authorization authentication of construction sites can be achieved. This method not only improves the safety and management efficiency of construction sites, but also promotes the intelligent and standardized development of safety management through data recording and processing.

[0075] As an optional manner, the safety regulation detection at least includes a helmet wearing detection.

[0076] Specifically, in the safety regulation inspection of construction sites, in addition to the safety helmet wearing inspection, other safety regulation inspection items may also include protective clothing inspection, safety shoes inspection, protective glasses inspection and gloves inspection.

[0077] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the control method of the substation electronic safety fence of the present application will be described in detail below in combination with specific embodiments.

[0078] This embodiment relates to a specific control method for a substation electronic safety fence, including the following steps:

[0079] Step S1: Input work ticket information and extract work construction point coordinate data;

[0080] Step S2: Calculate the safety distance value according to the coordinate data of the operation construction point and set the electronic fence area;

[0081] Specifically, in step S2, after obtaining the coordinate data of the operation construction point, the electronic fence is generally set as a rectangle, and the electronic fence positions of the four coordinate points are determined by the horizontal and vertical safety distances. Sometimes, when the operation positions of several work tickets are close, the distance between the construction operation points will be less than the horizontal or vertical safety distance. When the distance between the construction operation points is less than the safety distance, the construction operation area is merged. The adjacent intervals between the construction operation points are used as the entrance and exit of the electronic fence area.

[0082] Step S3: Manually input the entrance and exit of the electronic fence area;

[0083] Step S4: placing the electronic fence pillars in sequence to the set positions on site, wherein the area between the first electronic fence pillar and the last electronic fence pillar is the entrance and exit;

[0084] Step S5: Among two adjacent electronic fence pillars (except the left and right electronic fence pillars at the entrance and exit), the infrared transmitting unit of one electronic fence pillar transmits infrared rays to the infrared receiving unit of the other electronic fence pillar; the infrared receiving unit determines whether a light signal is received, and if a light signal is received, the camera continues to monitor; if no light signal is received, the camera records a video, and the video image is sent to the background system, and a first alarm signal is issued;

[0085] Step S6: The infrared transmitting unit of one of the left and right electronic fence pillars at the entrance and exit transmits infrared rays to the infrared receiving unit of the other electronic fence pillar; the infrared receiving unit determines whether a light signal is received. If a light signal is received, the camera continues to monitor. When no light signal is received, the video camera records the video and sends the video image to the background system. The background system obtains the face image from the video, authenticates and identifies the personnel entering the construction area, and triggers the first alarm signal if the personnel do not have permission.

[0086] Specifically, in step S6, the video image is sent to the background system, and the background system obtains the face image and performs authority authentication and identification on the personnel entering the construction area, as follows:

[0087] Step S61, obtaining a real-time video stream captured by a video camera;

[0088] By connecting to the video camera, the real-time video stream of the camera can be obtained. For example, the opencv open source library can be used to read the RTSP (Real Time Streaming Protocol) video stream to provide a data source for face recognition.

[0089] Step S62, parse the real-time video stream, detect the moving target through the moving target detection technology to obtain an image with a face, and then extract the face features through the face recognition algorithm to obtain the structured data of the face and form the feature value of the face. Specifically, the image with the face is obtained through background subtraction based on mixed Gaussian model modeling. The image with the face is preprocessed, including image grayscale, face registration, image enhancement and filtering. The preprocessed image retains the most essential part of the face that is most beneficial to feature extraction, and filters out some external interference factors such as light, decorations, etc., and then uses the convolutional neural algorithm to extract features from the preprocessed image to form the feature value of the face;

[0090] Step S63, performing face recognition in a face database using the feature values ​​of the face to obtain face identity information;

[0091] Step S64: Authorization authentication and identification are performed based on the facial identity information. The facial information stored in the facial database is pre-labeled with a label indicating whether the person can enter the construction area. When the facial identity information cannot be matched with the information in the facial database, a first alarm signal is triggered and sent to the electronic fence pillar to remind the on-site personnel to leave and the monitoring personnel at the same time.

[0092] Step S7: The background system performs a safety standard detection on the facial image in step S6, and triggers a second alarm signal if the safety standard is not met.

[0093] Specifically, in step S2, after obtaining the coordinate data of the operation construction point, the electronic fence is generally set as a rectangle, and the electronic fence positions of the four coordinate points are determined by the horizontal and vertical safety distances. Sometimes, when the operation positions of several work tickets are close, the distance between the construction operation points will be less than the horizontal or vertical safety distance. When the distance between the construction operation points is less than the safety distance, the construction operation area is merged. The adjacent intervals between the construction operation points are used as the entrance and exit of the electronic fence area.

[0094] Specifically, the safety standard detection of the face image in step S7 includes two aspects: the helmet detection of the face image at the entrance and exit and the detection that the construction worker did not enter through the set entrance and exit.

[0095] The helmet detection of the face image at the entrance and exit includes the following steps: the face feature value extracted after step S52 is sent to the helmet wearing classification model for classification judgment to judge whether the person in the image is wearing a helmet, and the judgment result is recorded. After step S54, when the face identity information matches the information in the face database, the helmet wearing judgment result is retrieved. If the person is wearing a helmet, no alarm signal is triggered; if the person is not wearing a helmet, a second alarm signal is triggered.

[0096] After the electronic fence pillars other than the two electronic fence pillars on the left and right of the entrance and exit send out the first alarm signal in step S5, the video captured by the camera is sent to the background system, and the facial identity information is determined to be matched with the information in the facial database according to steps S61-S64. If so, an auxiliary warning is added after the first alarm signal is sent to remind the monitor that it is because the construction workers did not enter according to the designated entrance and exit, and the alarm level is lowered; if there is no match, no signal is sent. The processing strategies corresponding to different alarm signal levels are shown in Table 1.

[0099] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0100] The embodiment of the present application also provides a control device for an electronic safety fence of a substation. It should be noted that the control device for an electronic safety fence of a substation in the embodiment of the present application can be used to execute the control method for an electronic safety fence of a substation provided in the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and those that have been described will not be repeated here. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

[0101] The following is an introduction to the control device of the substation electronic safety fence provided in an embodiment of the present application.

[0102] Figure 4 1 is a structural block diagram of a control device for a substation electronic safety fence according to an embodiment of the present application. Figure 4 As shown, the device includes: a first acquisition unit 10, a first determination unit 20, a first control unit 30 and a second control unit 40.

[0103] The first acquisition unit 10 is used to acquire work ticket information, extract coordinate data of the operation construction point according to the work ticket information, and obtain a first target position;

[0104] Specifically, the work ticket information currently in progress is obtained from the substation management system or related equipment, and the specific coordinate data of the work construction point is extracted from the work ticket information. These data are usually recorded in safety-related documents or systems. Based on the extracted coordinate data, the specific location of the work construction point, that is, the first target location, is determined.

[0105] A first determining unit 20 determines a setting area of ​​the electronic fence based on the first target position and a preset safety distance to obtain a plurality of second target positions;

[0106] Specifically, according to the safety specifications and operation type of the substation, a safety distance is preset (for example, 5 meters around the operation point). Based on the first target position and the preset safety distance, the area that the electronic fence needs to cover is calculated. According to the calculated area, the specific positions of the electronic fence support columns are determined, and multiple second target positions are generated.

[0107] The first control unit 30 controls the movement of the electronic fence support poles according to the second target position until each electronic fence support pole reaches the corresponding second target position;

[0108] Specifically, confirm the current position of each electronic fence support post, and control the electronic fence support post to move to the corresponding position according to the second target position determined in step S302. During the movement, the position of the support post is monitored in real time through sensors or positioning systems to ensure that they accurately reach the second target position.

[0109] The second control unit 40 activates the infrared emitting device of each electronic fence support column to realize real-time monitoring of the entry and exit of the operating personnel.

[0110] Specifically, when all the electronic fence support posts have reached the corresponding second target position, the infrared radiation device on each support post is activated. The infrared radiation device starts to work and monitors the operation area in real time to prevent unauthorized personnel from entering or operators from leaving the designated area. If an abnormal entry or exit is detected, the alarm system is triggered to notify relevant personnel to handle it.

[0111] The present application discloses a device for constructing an electronic fence of a substation, and the device includes: a first acquisition unit, a first determination unit, a first control unit, and a second control unit. The device obtains the coordinates of the construction point through the work ticket information to ensure that the operators work in a legal and safe area, which helps to avoid unauthorized operations. According to the acquired coordinate information of the operation construction point and the set safety distance, the electronic fence is ensured to accurately enclose the operation area and reduce the probability of accidents. The activated infrared counter-radiation device can monitor the entry and exit of personnel in real time, detect abnormal behavior in time, and reduce safety hazards. A traceable management system is formed for the entire process from obtaining the work ticket to setting up the electronic fence, which improves the management standardization. The problem of operators mistakenly entering the construction area and causing accidents in the prior art during the operation of the substation is solved.

[0112] As an optional manner, the first determining unit includes: a second determining module and a third determining module.

[0113] A second determination module is used to determine the corresponding second target positions with each first target position as the center when the distance between the first target positions corresponding to each work ticket information is greater than or equal to twice the preset safety distance, and the distance between the boundary of the first target position and the boundary of the corresponding second target position is greater than or equal to the preset safety distance;

[0114] Specifically, the location information of each specific operation is obtained from the relevant work ticket, including the operation type, location coordinates, etc. The area where the current operation is actually performed, that is, the first target location, is determined based on the operation information. The actual distance between each first target location is calculated using geographic coordinates or other location recognition technology, and compared with the preset safety distance to confirm whether there is a potential safety hazard. If the distance between each first target location is greater than or equal to twice the preset safety distance, it indicates that these operation areas can be carried out safely and independently.

[0115] It can be seen that, with each first target position as the center, a corresponding second target position is established to ensure that the distance between the boundary of each first target position and the boundary of the corresponding second target position is greater than or equal to the preset safety distance.

[0116] The third determination module is used to merge the first target positions corresponding to the work ticket information to obtain at least one third target position when the distance between the first target positions corresponding to the work ticket information is less than twice the preset safety distance, and determine the corresponding second target position with the third target position as the center, and the distance between the boundary of the third target position and the corresponding second target position is greater than or equal to the preset safety distance.

[0117] Specifically, if the distance between any two first target positions is less than twice the preset safety distance, it means that there is a risk of mutual interference in their working areas. All first target positions that meet the merging conditions will be merged to form at least one new working area, namely the third target position. The newly determined third target position and its corresponding second target position will be marked on the spot, and obvious warning signs and visual identification can be used to remind operators to pay attention to the safety area.

[0118] In summary, through the above process, the work ticket information of the construction site can be effectively integrated, the operation area can be reasonably planned, and sufficient safety distance can be ensured, thereby improving the safety management level of the construction site. This method not only helps to ensure the safety of the workers, but also improves the construction efficiency and is conducive to the optimization of the overall project management.

[0119] As an optional manner, the device further includes: a target location unit and an entrance and exit determination unit.

[0120] A target position unit, used to obtain the operation content when the distance between the first target positions corresponding to the work ticket information is greater than or equal to twice the preset safety distance, and to set an entrance and exit for the operator in the second target position based on the operation content, so as to obtain at least one third target position, wherein the second target position includes the third target position;

[0121] Specifically, with the first target position as the center, the second target position is set based on the preset safety distance to ensure safe isolation between working areas, and it is verified whether the distance between each first target position is greater than or equal to twice the preset safety distance to ensure the effectiveness of the safety area. The entrance and exit of the workers are planned in each second target position to ensure that its location is convenient for operation and does not interfere with other operations.

[0122] An entrance and exit determination unit is used to intercept the position corresponding to the second target position with the adjacent distance between the boundaries of each first target position when the distance between the first target positions corresponding to each work ticket information is less than twice the preset safety distance, and determine it as the entrance and exit corresponding to the first target position to obtain at least one third target position.

[0123] In summary, by deeply analyzing the adjacent distances of the boundaries of the work area, carefully intercepting the entrances and exits, and forming a reasonable third target position, the safety and work efficiency of the construction site can be significantly improved. This approach not only helps to ensure the safety of the workers, but also optimizes the space utilization and management layout, providing a solid foundation for the smooth progress of the project.

[0124] As an optional manner, the second control unit includes: a first alarm module and a second alarm module.

[0125] A first alarm module is used to control the infrared emitting device of each electronic fence support post to emit infrared rays to the electronic fence support posts on both sides when the electronic fence support post is at the second target position and at the third target position, and to control the infrared receiving unit of each electronic fence support post to receive the light signal emitted by the electronic fence support post on the opposite side, and to control the camera to perform portrait tracking to collect image data and issue a first alarm message when the infrared receiving unit does not receive the light signal, wherein the first alarm message is used to indicate the existence of illegal intrusion into the construction area;

[0126] It can be seen that by utilizing electronic fence support columns and infrared counter-shooting technology, combined with camera tracking, real-time monitoring and rapid alarm of illegal intrusions into the construction area can be achieved, which can significantly improve the level of safety management on site.

[0127] The second alarm module is used to control the infrared emitting device of each electronic fence support post to emit infrared rays to the electronic fence support posts on both sides when the electronic fence support post is in the third target position, and control the infrared receiving unit of each electronic fence support post to receive the light signal emitted by the electronic fence support post on the opposite side; when the infrared receiving unit does not receive the light signal, extract the operator information and safety measures information from the work ticket information, and control the camera to perform portrait tracking to collect image data, perform authority authentication based on the image data and the operator information, and issue a first alarm message if the authority authentication fails, and perform a safety specification detection based on the image data and the safety measures information if the authority authentication passes, and issue a second alarm message if the safety specification detection fails, and the second alarm message is used to indicate that the operator's safety specification detection fails.

[0128] In summary, through the comprehensive application of electronic fence support columns, infrared beam devices, cameras, and work ticket information, it is possible to achieve strict monitoring of the authority authentication and safety regulations of operators at the construction site. This not only improves the safety of the construction area, but also strengthens the management and responsibility of personnel, providing a strong guarantee for achieving a safe and efficient construction environment.

[0129] As an optional manner, the second control unit further includes: a third alarm module.

[0130] The third alarm module is used to extract the operating personnel from the work ticket information and perform authority authentication based on the image data and the operating personnel information. If the authority authentication is passed, a third alarm message is issued. The third alarm message is used to indicate that the operating personnel did not enter according to the prescribed entrance and exit.

[0131] It can be seen that by combining work ticket information, image data and authority authentication, and implementing a strict entrance and exit management process, it is possible to effectively ensure that workers enter and exit according to the prescribed entrances and exits, and promptly detect and deal with violations. This method not only improves the safety of the construction site, but also improves the overall safety management level through detailed records and rapid response, providing a strong guarantee for achieving a safe and efficient construction environment.

[0132] As an optional manner, the second alarm module includes: a first image submodule, a second image submodule, a feature extraction submodule, a matching submodule and a matching determination submodule.

[0133] A first image submodule is used to obtain a real-time video stream of a camera, and determine a region corresponding to a human portrait in the real-time video stream based on motion target monitoring to obtain first image data;

[0134] Specifically, real-time video stream data is obtained from surveillance cameras installed at the main entrances and exits of the construction site. Moving target detection algorithms (such as optical flow method and background difference method) are used to determine moving objects in the video stream, mainly focusing on detecting the portrait area. The area containing the portrait is extracted to form the first image data for subsequent face detection.

[0135] The second image submodule is used to perform face detection based on the first image data by using a background subtraction method modeled by a Gaussian mixture model, extract an area corresponding to the face in the portrait area, and obtain second image data;

[0136] Specifically, a Gaussian mixture model (GMM) is used to model the background, and background subtraction is used to distinguish the foreground (portrait) from the background. The face area in the first image data is detected, and the face position is accurately determined using face recognition technology (such as Haar features and HOG features). The second image data is extracted, containing the accurate face area, for subsequent feature extraction.

[0137] A feature extraction submodule, used for performing preprocessing based on the second image data and extracting features through a convolutional neural network to obtain a target feature value, wherein the preprocessing includes at least graying, face registration, data enhancement and image filtering;

[0138] Specifically, a pre-trained convolutional neural network (such as ResNet and VGGNet) is used to perform deep feature extraction on the preprocessed image to obtain the target feature value.

[0139] A matching submodule is used to determine the face identity information by matching in a preset face database based on the target feature value, and to match the face identity information with the operator information, wherein the preset face database includes the face data and corresponding identity information of all operators;

[0140] Specifically, the target feature value is compared with the feature value in the face database, the face identity information is determined by similarity calculation, and the identified identity information is matched with the extracted operator information to confirm whether it is an authorized person.

[0141] The matching determination submodule is used to determine that the permission authentication is passed when the facial identity information matches the operator information, and to determine that the permission authentication is failed when the facial identity information does not match the operator information.

[0142] Specifically, if the facial identity information matches the operator information successfully, it is determined that the permission authentication is passed, and the person is allowed to enter or operate. If the match fails, it is determined that the permission authentication is not passed, an alarm message is issued, and unauthorized personnel are denied entry or operation.

[0143] In summary, by combining cameras, face recognition, convolutional neural networks and face databases, refined and intelligent real-time monitoring and authorization authentication of construction sites can be achieved. This method not only improves the safety and management efficiency of construction sites, but also promotes the intelligent and standardized development of safety management through data recording and processing.

[0144] As an optional manner, the device further includes: a detection unit.

[0145] The detection unit is at least used for helmet wearing detection.
