[0030] A control method of a substation electronic security fence running on a mobile terminal, a computer terminal or the like computing device is provided in the embodiment. 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 sequence is shown in the flowchart, in some cases, the steps shown or described herein can be executed in a different order.

[0031] Figure 3 is a flowchart of the control method of the substation electronic security fence according to the embodiment of the present application. As shown in Figure 3 , the method comprises the following steps:

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

[0033] Specifically, the work ticket information currently being performed 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. According to the extracted coordinate data, the specific position of the work construction point, i.e. the first target position, is determined.

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

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

[0036] Step S303, controlling the electronic fence support columns to move according to the second target positions until each electronic fence support column reaches the corresponding second target position;

[0037] Specifically, the current positions of the electronic fence support columns are confirmed, and the electronic fence support columns are controlled to move to the corresponding positions according to the second target positions determined in step S302. During the movement, the positions of the support columns are monitored in real time by sensors or positioning systems to ensure that they accurately reach the second target positions.

[0038] Step S304, activating the infrared opposite shooting devices of each electronic fence support column to realize real-time monitoring of the work personnel entering and exiting.

[0039] Specifically, when all the electronic fence support columns reach the corresponding second target positions, the infrared opposite shooting devices on the support columns are activated. The infrared opposite shooting devices start to work and monitor the working area in real time to prevent unauthorized personnel from entering or the working personnel from leaving the designated area. If an abnormal entering or leaving situation is detected, the alarm system is triggered to inform the relevant personnel to handle it.

[0040] In summary, by obtaining the construction point coordinates from the work ticket information, it is ensured that the working personnel work in a legal and safe area, which helps to avoid unauthorized work behavior. According to the obtained work construction point coordinate information and the set safety distance, it is ensured that the electronic fence accurately encloses the working area, which reduces the probability of accidents. The activated infrared opposite shooting device can monitor the personnel entering and leaving in real time, timely discover abnormal behavior, and reduce safety hazards. The entire process from obtaining the work ticket to setting the electronic fence forms a traceable management system, which improves the management standardization.

[0041] As an optional way, the setting area of the electronic fence is determined based on the first target position and the preset safety distance, and a plurality of second target positions are obtained, including the following steps:

[0042] In step S401, in the case that the distance between each first target position corresponding to the work ticket information is greater than or equal to twice the preset safety distance, the corresponding second target position is determined with each first target position 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 position information of each specific work is obtained from the relevant work ticket, including the work type, position coordinates, etc. The actual working area, i.e. the first target position, is determined according to the work information. The actual distance between each first target position is calculated by using geographic coordinates or other position 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 position is greater than or equal to twice the preset safety distance, it indicates that these work areas can be safely and independently carried out.

[0044] Therefore, the corresponding second target position is set with each first target position as the center, and the distance between the boundary of each first target position and the corresponding second target position is greater than or equal to the preset safety distance.

[0045] In step S402, in the case that the distance between each first target position corresponding to the work ticket information is less than twice the preset safety distance, each first target position is merged to obtain at least one third target position, and the corresponding second target position is determined with the third target position as the center. The distance between the third target position and the boundary of 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, indicating that there is a risk of mutual interference in their work areas, all first target positions that meet the merging condition are merged to form at least one new work area, i.e., a third target position. The newly determined third target position and its corresponding second target position are marked in the field, and obvious warning signs and visual identifiers can be used to remind workers to pay attention to safety areas.

[0047] In summary, through the above process, the work ticket information of the construction site can be effectively integrated, the work 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 workers, but also improves the construction efficiency, which is conducive to the optimization of overall project management.

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

[0049] Step S501, in the case where the distance between the first target positions corresponding to each work ticket information is greater than or equal to twice the preset safety distance, obtaining the work content, and setting the entrance and exit of the work personnel in the second target position based on the work content to obtain at least one third target position, the second target position including the third target position;

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

[0051] In the case where 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 corresponding position of the second target position to determine the entrance and exit of the corresponding first target position to obtain at least one third target position.

[0052] In summary, by deeply analyzing the adjacent distance of the work area boundary and finely intercepting the entrance and exit to form a reasonable third target position, the safety and work efficiency of the construction site can be significantly improved. This method not only helps to ensure the safety of 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 mode, the electronic fence support column further comprises an infrared receiving unit, a camera and an alarm unit, and the infrared transmitting and receiving device of each electronic fence support column is activated to realize real-time monitoring of the access of the working personnel, including:

[0054] In step S601, when the electronic fence support column is in the second target position and in the third target position, the infrared transmitting and receiving 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 signals emitted by the electronic fence support columns on the opposite side. If the infrared receiving unit does not receive the light signals, the camera is controlled to perform portrait tracking to collect image data, and a first alarm information is sent, which is used to represent the case that there is 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, i.e. in the case that the above-mentioned electronic fence support column is in the fence area, whether someone illegally intrudes into the construction area is monitored in real time by the infrared transmitting and receiving device. If the infrared rays are blocked, the camera detects the intruder and alarms.

[0056] When the electronic fence support column is in the third target position, the infrared transmitting and receiving 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 signals emitted by the electronic fence support columns on the opposite side. If the infrared receiving unit does not receive the light signals, the working personnel information and safety measure information are extracted from the work ticket information, and the camera is controlled to perform portrait tracking to collect image data. Based on the image data and the working personnel information, the authority authentication is performed. If the authority authentication is not passed, the first alarm information is sent. If the authority authentication is passed, the safety specification detection is performed based on the image data and the safety measure information. If the safety specification detection is not passed, the second alarm information is sent, which is used to represent that the safety specification detection of the working personnel is unqualified.

[0057] Specifically, when the electronic fence support column is in the third target position, i.e. in the case that the above-mentioned electronic fence support column is used to detect the entrance, whether someone passes through is detected by the infrared transmitting and receiving device. If it is detected that there is an entering person, the camera collects face data for identity matching to avoid non-working personnel from entering. If the matching is not passed, illegal intrusion alarm is performed. If the identity matching is passed, further detection is performed based on the image data to ensure that the safety measures of the working personnel are qualified. If the safety measures are unqualified, an alarm is performed to prompt the working personnel to arrange.

[0058] In summary, through the comprehensive application of electronic fence support column, infrared pair-shooting device, camera, and work ticket information, the permission authentication and strict monitoring of safety regulations of the operating personnel in the construction site can be realized. This not only improves the safety of the construction area, but also strengthens the management and responsibility implementation of personnel, and provides a strong guarantee for realizing a safe and efficient construction environment.

[0059] As an optional way, after controlling the camera to track the portrait to collect image data and send the first alarm information, the method further includes:

[0060] extracting the operating personnel from the work ticket information, and performing permission authentication based on the image data and the operating personnel information, and sending the third alarm information in the case that the permission authentication is passed, the third alarm information being used to represent that the operating personnel enters the entrance according to the regulations.

[0061] In the case that the personnel illegally enters the fence area, identity matching is performed, and in the case that the matching is passed, it is determined that the operating personnel enters the non-standard position, and the alarm level will be increased.

[0062] Therefore, by combining the work ticket information, image data and permission authentication, and implementing a strict entrance and exit management process, it can be effectively ensured that the operating personnel enters and exits according to the regulations, and the illegal behavior can be found and handled in time. 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, and provides a strong guarantee for realizing a safe and efficient construction environment.

[0063] As an optional way, controlling the camera to track the portrait to collect image data, and performing permission authentication based on the image data and the operating personnel information includes the following steps:

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

[0065] Specifically, real-time video stream data is obtained from the monitoring camera installed at each main entrance and exit of the construction site. The moving objects in the video stream are determined using a motion target detection algorithm (such as optical flow method, background difference method), mainly focusing on detecting the portrait area. The area containing the portrait is extracted to form the first image data, which is used for subsequent face detection.

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

[0067] Specifically, the background is modeled using a Gaussian Mixture Model (GMM), and the foreground (portrait) is distinguished from the background by background subtraction. The face region in the first image data is detected, and a face recognition technique (such as Haar features, HOG features) is used to accurately determine the face position. The second image data is extracted, containing the accurate face region, for subsequent feature extraction.

[0068] Step 603, based on the second image data, pre-processing and feature extraction by convolutional neural network are performed to obtain target feature values, and the pre-processing at least includes graying, face registration, data enhancement and image filtering;

[0069] Specifically, a pre-trained convolutional neural network (such as ResNet, VGGNet) is used to extract deep features from the pre-processed image to obtain target feature values.

[0070] Step 604, based on the target feature values, the face identity information is determined by matching in the preset face database, and the face identity information is matched with the worker information, and the preset face database includes face data and corresponding identity information of all workers;

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

[0072] Step 605, if the face identity information and the worker information match, it is determined that the permission authentication is passed, and if the face identity information and the worker information do not match, it is determined that the permission authentication is not passed.

[0073] Specifically, if the face identity information and the worker information match successfully, it is determined that the permission authentication is passed, and the person is allowed to enter or work. If the matching fails, it is determined that the permission authentication is not passed, and an alarm information is sent to refuse the non-authorized person to enter or work.

[0074] In summary, by combining the camera, face recognition, convolutional neural network and face database, real-time monitoring and permission authentication of the construction site are realized. 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.

[0075] As an optional way, the safety specification detection at least includes safety helmet wearing detection.

[0076] Specifically, in the safety specification detection of the construction site, in addition to the safety helmet wearing detection, it can also include protective clothing detection, safety shoes detection, protective glasses detection and glove detection, etc. safety specification detection items.

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

[0078] The present embodiment relates to a specific control method of a substation electronic safety fence, comprising the following steps:

[0079] Step S1: input work ticket information, extract work construction point coordinate data;

[0080] Step S2: calculate the safety distance value according to the work construction point coordinate data, and set the electronic fence area;

[0081] Specifically, in step S2, after obtaining the work construction point coordinate data, the electronic fence is generally set as a rectangle, and the positions of the electronic fence of the four coordinate points are determined through the horizontal and vertical safety distances. Sometimes, several work ticket work positions are adjacent, and the distance between the work construction points may be less than the horizontal or vertical safety distance. When the distance between the work construction points is less than the safety distance, the work construction areas are merged. The adjacent interval between the work construction points is taken 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: sequentially place the electronic fence supports to the set positions on site, wherein the area between the first electronic fence support and the last electronic fence support is the entrance and exit;

[0084] Step S5: in the two adjacent electronic fence supports (except the left and right electronic fence supports of the entrance and exit), the infrared emission unit of one of the electronic fence supports emits infrared rays to the infrared receiving unit of the other electronic fence support; the infrared receiving unit judges whether the light signal is received, if the light signal is received, the camera continues to monitor; if the light signal is not received, the camera records the video, the video image is sent to the background system, and the first alarm signal is sent;

[0085] Step S6: the left and right electronic fence supports of the entrance and exit, the infrared emission unit of one of the electronic fence supports emits infrared rays to the infrared receiving unit of the other electronic fence support; the infrared receiving unit judges whether the light signal is received, if the light signal is received, the camera continues to monitor, when the light signal is not 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, and the personnel entering the work construction area are authenticated and identified, if there is no permission, the first alarm signal is triggered.

[0086] Specifically, in step S6, the video image is sent to the background system, the background system obtains the face image, and the personnel entering the construction operation area are authenticated and identified, and the specific steps are as follows:

[0087] Step S61, obtaining the real-time video stream photographed by the video camera;

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

[0089] Step S62, analyzing the real-time video stream, detecting the moving target through the moving target detection technology to obtain the image with the face, and extracting the face feature through the face recognition algorithm to obtain the structured data of the face and form the feature value of the face. Specifically, the background subtraction based on the Gaussian mixture model is used to obtain the image with the face. The image with the face is preprocessed, including image graying, face registration, image enhancement and filtering. The image after preprocessing retains the most essential part of the face and is most beneficial to feature extraction, and filters out external interference factors such as light and ornaments, and then a convolution neural algorithm is selected to extract features from the preprocessed image, and then the feature value of the face is formed;

[0090] Step S63, face recognition through the feature value of the face in the face database to obtain the face identity information;

[0091] Step S64, performing permission authentication and identification according to the face identity information, and the stored face information in the face database is labeled with a label in advance, indicating whether it can enter the construction operation area. When the face identity information cannot be matched to the information in the face database, a first alarm signal is triggered to send to the electronic fence support, reminding the on-site personnel to leave and reminding the monitoring personnel.

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

[0093] Specifically, in step S2, after obtaining the construction point coordinate data, the electronic fence is generally set as a rectangle, and the positions of the four coordinate points of the electronic fence are determined through the horizontal and vertical safety distances. Sometimes, several work ticket operation positions are close to each other, and the distance between the construction operation points is 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 areas are combined. The adjacent interval between the construction operation points is taken as the entrance and exit of the electronic fence area.

[0094] Specifically, the safety regulation detection on the face image in step S7 includes two aspects of safety helmet detection on the face image of the entrance and detection that the construction worker does not enter through the set entrance.

[0095] The safety helmet detection on the face image of the entrance includes the following steps: after the face feature value extracted in step S52 is sent to the safety helmet wearing classification model for classification judgment, whether the personnel in the image wears a safety helmet is judged, and the judgment result is recorded. When the face identity information matches the information in the face database after step S54, the safety helmet wearing judgment result is called, if the safety helmet is worn, the alarm signal is not triggered; if the safety helmet is not worn, the second alarm signal is triggered.

[0096] After the electronic fence support other than the left and right electronic fence supports of the entrance sends the first alarm signal in step S5, the video captured by the camera is sent to the background system, and whether the face identity information matches the information in the face database is judged according to steps S61-S64, if yes, an auxiliary warning is added after the first alarm signal is sent, reminding the monitor that the construction worker does not enter through the designated entrance, and the alarm level is reduced; if not, 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 flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.

[0100] The embodiment of the present application also provides a control device of the electronic safety fence of the transformer substation. It should be noted that the control device of the electronic safety fence of the transformer substation of the embodiment of the present application can be used to execute the control method for the electronic safety fence of the transformer substation provided by the embodiment of the present application. The device is used to realize the above-mentioned embodiment and preferred embodiment, and the description is not repeated. As used below, the term "module" can be a combination of software and / or hardware that realizes a predetermined function. Although the device described in the following embodiment is preferably realized in software, the realization of hardware, or a combination of software and hardware, is also possible and conceived.

[0101] The control device of the electronic safety fence of the transformer substation provided by the embodiment of the present application is introduced below.

[0102] Figure 4 is a structure block diagram of the control device of the electronic safety fence of the transformer substation according to the embodiment of the present application. AsFigure 4 As shown, the device comprises 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 configured to acquire work ticket information, extract coordinate data of a work construction point from the work ticket information, and obtain a first target position.

[0104] Specifically, the work ticket information of the current ongoing work is acquired 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. According to the extracted coordinate data, the specific position of the work construction point, i.e., the first target position, is determined.

[0105] The first determination unit 20 determines the setting area of the electronic fence based on the first target position and a preset safety distance, and obtains a plurality of second target positions.

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

[0107] The first control unit 30 controls the movement of the electronic fence support columns according to the second target positions, until each electronic fence support column reaches the corresponding second target position.

[0108] Specifically, the current positions of the electronic fence support columns are confirmed, and the electronic fence support columns are controlled to move to the corresponding positions according to the second target positions determined in step S302. During the movement, the positions of the support columns are monitored in real time by sensors or positioning systems to ensure that they accurately reach the second target positions.

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

[0110] Specifically, when all the electronic fence support columns reach the corresponding second target positions, the infrared counter-shooting devices on the support columns are activated. The infrared counter-shooting devices start working and monitor the work area in real time to prevent unauthorized personnel from entering or work personnel from leaving the designated area. If an abnormal entry or exit is detected, the alarm system is triggered to notify the relevant personnel to handle it.

[0111] The application discloses a construction device of an electronic fence of a transformer substation, and the device comprises a first acquisition unit, a first determination unit, a first control unit and a second control unit. The device acquires construction point coordinates through work ticket information, ensures that workers work in a legal and safe area, and helps to avoid unauthorized work behaviors. According to the acquired work construction point coordinate information and the set safety distance, the electronic fence is ensured to accurately enclose the work area, and the probability of unexpected accidents is reduced. The activated infrared opposite-shooting device can monitor the personnel access in real time, timely find abnormal behaviors, and reduce safety hazards. The whole process from the work ticket to the electronic fence setting forms a traceable management system, and the management standardization is improved. The problem that workers misenter the construction area in the work process of the transformer substation in the prior art leads to unexpected accidents is solved.

[0112] As an optional mode, the first determination unit comprises a second determination module and a third determination module.

[0113] The second determination module is configured to, in a case where distances between the first target positions corresponding to the work ticket information are greater than or equal to twice the preset safety distance, determine, as the center of each first target position, a corresponding second target position, 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 position information of each specific work is acquired from the related work ticket, including the work type, the position coordinate and the like, the work information is used to determine the current actual work area, that is, the first target position, the geographical coordinate or other position recognition technology is used to calculate the actual distance between the first target positions, the actual distance is compared with the preset safety distance, and it is confirmed whether there is a potential safety hazard. If the distance between the first target positions is greater than or equal to twice the preset safety distance, it is indicated that the work areas can be safely and independently carried out.

[0115] Therefore, the corresponding second target position is set as the center of each first target position, and 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 configured to, in a case where the distance between the first target positions corresponding to the work ticket information is less than twice the preset safety distance, combine the first target positions to obtain at least one third target position, determine, as the center of the third target position, a corresponding second target position, and the distance between the third target position and the boundary of 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, indicating that there is a risk of mutual interference in their work areas, all first target positions that meet the merging condition are merged to form at least one new work area, i.e., a third target position. The newly determined third target position and its corresponding second target position are marked in the field, and obvious warning signs and visual identifiers can be used to remind workers to pay attention to safety areas.

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

[0119] As an optional way, the device further comprises a target position unit and a determination entrance and exit unit.

[0120] The target position unit is configured to, in a case where 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, the second target position including the third target position.

[0121] Specifically, the second target position is set based on the preset safety distance with the first target position as the center, to ensure the safety isolation between work areas, and to verify 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 the position is convenient for operation and does not interfere with other work.

[0122] The determination entrance and exit unit is configured to, in a case where the distance between the first target positions corresponding to the work ticket information is less than twice the preset safety distance, intercept the adjacent distance between the boundaries of each first target position at the corresponding position of the second target position to determine the entrance and exit of the corresponding first target position, to obtain at least one third target position.

[0123] In summary, by deeply analyzing the adjacent distance of the work area boundary and finely intercepting the entrance and exit, a reasonable third target position is formed, which can significantly improve the safety and work efficiency of the construction site. This way not only helps to protect the safety of 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 way, the second control unit comprises a first alarm module and a second alarm module.

[0125] The first alarm module is configured to control the infrared emitting and receiving device of each electronic fence support column to emit infrared rays to the electronic fence support columns on both sides when the electronic fence support column is in the second target position and the third target position, control the infrared receiving unit of each electronic fence support column to receive the light signals emitted by the electronic fence support columns on the opposite side, control the camera to perform portrait tracking to collect image data when the infrared receiving unit does not receive the light signals, and send a first alarm information, which is used to indicate that there is an illegal intrusion into the construction area.

[0126] Therefore, by using the electronic fence support column and the infrared emitting and receiving technology, combined with the camera tracking, real-time monitoring and rapid alarm of illegal intrusion into the construction area are realized, which can significantly improve the safety management level of the site.

[0127] The second alarm module is configured to control the infrared emitting and receiving device of each electronic fence support column to emit infrared rays to the electronic fence support columns on both sides when the electronic fence support column is in the third target position, control the infrared receiving unit of each electronic fence support column to receive the light signals emitted by the electronic fence support columns on the opposite side, extract the work personnel information and safety measure information from the work ticket information when the infrared receiving unit does not receive the light signals, control the camera to perform portrait tracking to collect image data, perform authority authentication based on the image data and the work personnel information, send a first alarm information when the authority authentication fails, perform safety specification detection based on the image data and the safety measure information when the authority authentication passes, and send a second alarm information when the safety specification detection fails, which is used to indicate that the safety specification detection of the work personnel is unqualified.

[0128] In summary, by comprehensively applying the electronic fence support column, the infrared emitting and receiving device, the camera, and the work ticket information, the authority authentication of the work personnel and the strict monitoring of the safety specification in the construction site can be realized. This not only improves the safety of the construction area, but also strengthens the management and responsibility implementation of the personnel, and provides a strong guarantee for realizing a safe and efficient construction environment.

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

[0130] The third alarm module is configured to extract the work personnel from the work ticket information, perform authority authentication based on the image data and the work personnel information, send a third alarm information when the authority authentication passes, and the third alarm information is used to indicate that the work personnel enters through an unauthorized entrance.

[0131] Therefore, by combining work ticket information, image data and permission authentication, implementing strict access management process can effectively ensure that the work personnel access in and out according to the regulations, and timely find and handle the irregular behavior. 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, and provides a strong guarantee for realizing a safe and efficient construction environment.

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

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

[0134] Specifically, real-time video stream data is obtained from the monitoring camera installed at each main access of the construction site. A motion target detection algorithm (such as optical flow method, background difference method) is used to determine the moving objects in the video stream, mainly focusing on detecting the portrait region. The region containing the portrait is extracted to form the first image data, which is used for subsequent face detection.

[0135] The second image submodule is configured to perform face detection based on the first image data through background subtraction modeled by a Gaussian mixture model, extract a region corresponding to a face in the portrait region, and obtain second image data.

[0136] Specifically, the background is modeled by a Gaussian mixture model (GMM), and the foreground (portrait) and background are distinguished by background subtraction. The face region in the first image data is detected, and the face recognition technology (such as Haar feature, HOG feature) is used to accurately determine the face position. The second image data containing the accurate face region is extracted for subsequent feature extraction.

[0137] The feature extraction submodule is configured to pre-process the second image data and extract features through a convolutional neural network to obtain target feature values, and the pre-processing at least includes grayscale, face registration, data enhancement and image filtering.

[0138] Specifically, a pre-trained convolutional neural network (such as ResNet, VGGNet) is used to extract deep features from the pre-processed image to obtain target feature values.

[0139] The matching submodule is configured to match the target feature values in a preset face database to determine face identity information, and match the face identity information with the work personnel information, and the preset face database includes face data and corresponding identity information of all work personnel.

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

[0141] The matching determination submodule is configured to determine that the permission authentication is passed when the face identity information and the worker information are matched, and determine that the permission authentication is not passed when the face identity information and the worker information are not matched.

[0142] Specifically, if the face identity information and the worker information are matched successfully, it is determined that the permission authentication is passed, and the person is allowed to enter or work. If the matching fails, it is determined that the permission authentication is not passed, and an alarm information is sent to refuse the non-authorized person to enter or work.

[0143] In summary, by combining the camera, face recognition, convolutional neural network and face database, real-time monitoring and permission authentication of the construction site are realized. 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.

[0144] As an optional way, the device further comprises a detection unit.

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