[0048] The security protection system and method based on intelligent laser electronic fence provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0049] The following describes a security protection system based on an intelligent laser electronic fence, provided by an embodiment of this application. For example... Figure 1 As shown, the security protection system 100 may include a test security terminal 110 and a laser electronic fence 120 deployed at the target boundary of the power test area; The laser electronic fence 120 includes a transmitter 121 and a receiver 122. The transmitter 121 is used to transmit light signals to the receiver 122. The receiver 122 is used to monitor the transmission status of the light signals. When the light signals are detected to be blocked, it sends a blocking alarm signal to the test security terminal 110. The test security terminal 110 is used to generate a first alarm message in response to a shielding alarm signal, and to obtain the test status of the target device 130. If the test status of the target device 130 is "under test", it sends a power-off command to the target device 130.

[0050] The safety protection system based on the intelligent laser electronic fence provided in the embodiments of the present application can be applied to the technical field of power safety. For example, in a strong electric test site, a plurality of strong electric test devices, i.e., target devices 130, are deployed, which bear high voltage, large current, and are expensive and complex in structure. There are potential dangers in the test process, for example, an electric shock accident may be caused by an increase in current in the test, and electric shock injury may be caused by high voltage. If an irrelevant person mistakenly enters a high-risk area or touches the device during the test, an electric shock, electric shock, or other serious accidents may occur. The user can deploy the safety protection system provided in the embodiments of the present application in the strong electric test site, i.e., the power test area.

[0051] In the embodiments of the present application, the test security terminal 110 is the core control device of the safety protection system, which can be an industrial computer, a server, etc. installed with test security software.

[0052] The laser electronic fence 120 is a perimeter security system that uses light signals as a detection medium to detect intrusion behavior by emitting and receiving light signals.

[0053] In the embodiments of the present application, the laser electronic fence 120 is deployed at the target boundary of the power test area. The user can pre-set the target boundary of the power test area and deploy the laser electronic fence 120 according to the layout of the power test site, the deployment position of the target device 130, etc.

[0054] In some embodiments, the target boundary is the physical boundary of the power test area and / or the outer peripheral boundary of the target device.

[0055] In the embodiments of the present application, the physical boundary of the power test area refers to an entity isolation facility that separates the power test area from the external environment, which can be a fence, a fence, a barrier, etc. The outer peripheral boundary of the target device refers to the physical contour line of the outer edge of the target device, which can be determined according to the outermost edge of the shell, rack, and protruding parts of the target device 130.

[0056] In this embodiment, by determining the physical boundary of the power test area and / or the outer peripheral boundary of the target device 130 as the target boundary, the subsequent deployment of the laser electronic fence 120 at the target boundary can trigger a shielding alarm signal when a person enters the power test area and / or approaches the target device 130, thereby improving the safety protection level of the power test site.

[0057] In the embodiments of the present application, the interaction process between the test security terminal 110 and the laser electronic fence 120 is as shown in Figure 2

[0058] ​Step 210, the transmitting end 121 of the laser electronic fence 120 transmits an optical signal to the receiving end 122, and the receiving end 122 monitors the transmission state of the optical signal, and sends a shielding alarm signal to the test security terminal 110 in the case of monitoring that the optical signal is shielded.

[0059] In the embodiment of the present application, the laser electronic fence 120 includes the transmitting end 121 and the receiving end 122. The transmitting end 121 can include a light source, a modulation excitation power supply, a direction adjusting device, a communication module and the like, can communicate with the test security terminal 110 through the communication module, and send an optical signal with a certain power and frequency to the receiving end 122 according to the instruction issued by the test security terminal 110. The receiving end 122 can include a sensor, a photoelectric signal processor and a communication module and the like, can receive the optical signal sent by the transmitting end 121 through the sensor, and perform photoelectric conversion and signal processing by the photoelectric signal processor to monitor the transmission state of the optical signal, and communicate with the test security terminal 110 through the communication module.

[0060] When there is no object between the transmitting end 121 and the receiving end 122 of the laser electronic fence 120, the sensor of the receiving end 122 can receive the optical signal sent by the transmitting end 121, and then no operation is performed and the monitoring is continued. When there is an object or a person between the transmitting end 121 and the receiving end 122 of the laser electronic fence 120, the optical signal is shielded, the receiving end 122 monitors that the optical signal transmission is interrupted, and then it is determined that shielding occurs, and a shielding alarm signal is sent to the test security terminal 110.

[0061] Step 220, the test security terminal 110 generates first alarm information in response to the shielding alarm signal, and acquires the test state of the target device 130, and sends a power-off instruction to the target device 130 if the test state of the target device 130 is being tested.

[0062] The test security terminal 110 generates first alarm information after receiving the shielding alarm signal sent by the laser electronic fence 120. For example, the test security terminal 110 can play a prompt sound of "electronic fence is invaded" through a loudspeaker connected to the test security terminal 110 in a sound prompt manner to alarm; or the test security terminal 110 can send a short message of "electronic fence is invaded" to the user through the communication module; of course, the first alarm information can also be generated in other forms, which is not limited in the embodiment of the present application.

[0063] At the same time, the test security terminal 110 acquires the test state of the target device 130. The test state of the target device 130 can be manually set by the user; or the current and / or voltage in the power test area can be detected, and it is determined that the test state of the target device 130 is being tested when the current and / or voltage is greater than a preset threshold.

[0064] When the test state of the target device 130 is under test, the test security terminal 110 sends a power-off instruction to the target device 130 to control the target device 130 to power off.

[0065] In some embodiments, the target device 130 includes a power test device and a power device under test; the target device 130 is connected to the test security terminal 110 through a relay interface or a smart communication interface.

[0066] In the embodiments of the present application, the power test device refers to an instrument device used to apply test conditions and measure parameters during the power test, which can include a power supply device and a measuring instrument; the power device under test refers to the power device under test.

[0067] The relay is an electrical control device that can include an electromagnetic system and a contact system, and controls the on-off of the contacts through the attraction and release of the electromagnet, thereby controlling the on-off of the circuit. The relay interface refers to the component connecting the relay to other devices. The power supply relay of the target device 130 can be connected to the test security terminal 110 using the relay interface. When the relay interface receives the power-off instruction sent by the test security terminal 110, the electromagnet is released to make the contacts open, thereby disconnecting the power supply circuit of the target device 130 and powering off the target device 130. By connecting the target device 130 to the test security terminal 110 using the relay interface, the influence of delay and fluctuation in the signal transmission process on safety protection can be reduced.

[0068] The smart communication interface is a communication connection device that can include a hardware control circuit and communication and control software. The communication module of the target device 130 can be connected to the test security terminal 110 using the smart communication interface. When the smart communication interface receives the power-off instruction sent by the test security terminal 110, the smart communication interface converts the instruction according to the pre-set communication protocol, performs data encapsulation and verification processing, converts it into a power-off control signal suitable for the target device 130, and sends the power-off control signal to the communication module of each target device 130; after each target device 130 receives the power-off control signal, the power supply is cut off through the internal relay or circuit breaker to complete the power-off operation, and the power-off execution result is returned to the test security terminal 110 through the smart communication interface. The test process can also be monitored in real time by sending the running state and other data of the target device 130 to the test security terminal 110 through the smart communication interface. In this embodiment, by connecting the target device 130 to the test security terminal 110 using the smart communication interface, the control efficiency and automation level can be improved, thereby improving the efficiency of the safety protection system.

[0069] The safety protection system based on the intelligent laser electronic fence 120 provided in the embodiments of the present application can automatically generate an alarm information when the laser electronic fence 120 sends a shielding alarm signal, and automatically send a power-off instruction to the target device 130 when the test state of the target device 130 is in the test process, so as to reduce the safety hazards caused by the response lag of manual supervision, thereby improving the safety protection level of the power test site.

[0070] In some embodiments, the test security terminal 110 is further configured to record the shielding event and generate the prompt information if the test state of the target device 130 is not in the test process.

[0071] In the embodiments of the present application, when the test security terminal 110 receives the shielding alarm signal sent by the laser electronic fence 120, the test state of the target device 130 can be obtained by querying the test state value manually set by the user, detecting the current and / or voltage in the power test area, querying the running state data of the target device 130 through the intelligent communication interface, and the like.

[0072] When the test state of the target device 130 is not in the test process, the time when the shielding alarm signal is received, the position of the laser electronic fence 120 sending the shielding alarm signal, and the like can be recorded, the shielding event record can be generated, and the prompt information can be generated in the form of voice broadcast, sending of a short message, and the like to notify the user.

[0073] In this embodiment, by recording only the shielding event and generating the prompt information when the test state of the target device 130 is not in the test process and the environmental risk is low, the number of power-off times can be reduced, thereby protecting the target device 130.

[0074] In some embodiments, the light signal emitted by the transmitting end 121 includes a visible light signal and an invisible light signal; the receiving end 122 is further configured to synchronously monitor the transmission state of the visible light signal and the invisible light signal, and send the shielding alarm signal to the test security terminal 110 when it is monitored that the visible light signal and the invisible light signal are both shielded.

[0075] In the embodiments of the present application, the transmitting end 121 can be installed with multiple types of light sources or the modulation excitation power supply of the transmitting end 121 can be adjusted, so that the transmitting end 121 sends the visible light signal and the invisible light signal to the receiving end 122; at the same time, corresponding multiple sensors or corresponding optical signal processors can be installed on the receiving end 122 to monitor the transmission state of the visible light signal and the invisible light signal sent by the transmitting end 121.

[0076] In the case that the visible light signal and the invisible light signal are both blocked, only the visible light signal is blocked, or only the invisible light signal is blocked, it is determined that no blocking occurs, no operation is performed, and monitoring is continued; in the case that the visible light signal and the invisible light signal are both blocked, it is determined that blocking occurs, and a blocking alarm signal is sent to the test security terminal 110.

[0077] In this embodiment, by sending a blocking alarm signal to the test security terminal 110 when it is monitored that the visible light signal and the invisible light signal are both blocked, the situation of false alarm can be reduced.

[0078] In some embodiments, the security protection system further comprises an access control device 140 arranged at the entrance of the power test area; The access control device 140 is configured to collect personnel biometric information and upload it to the test security terminal 110. The test security terminal 110 is further configured to match the personnel biometric information with the permission database, and in the case of successful matching, open the access control and send an activation instruction to the transmitting end 121; the permission database stores the mapping relationship between different personnel biometric information and permissions. The transmitting end 121 is further configured to, in response to the activation instruction, transmit a light signal to the receiving end 122 to form a laser fence light curtain.

[0079] The access control device 140 is a kind of security management device, which controls the access of personnel in a specific area by identifying the identity of personnel and verifying the permission of personnel according to the verification result. The access control device 140 can be arranged at the entrance of the power test area, such as the automatic door of the power test room entrance, and only the automatic door is opened when the verification is passed.

[0080] In the embodiments of the present application, the access control device 140 can include a collection module, an identification module, a communication module, a control module, etc. The collection module is a device for collecting personnel biometric data, for example, the face image data or iris image data of personnel can be collected through a camera, and the fingerprint data of personnel can be collected through a fingerprint collector. The identification module is a device that uses a specific feature recognition algorithm to analyze the biometric data collected by the collection module to obtain biometric information, for example, an edge computing device equipped with a face recognition tool can be used as an identification module to analyze the personnel face image data collected by the collection module to extract a face feature vector as biometric information. The communication module is a device for communicating with the test security terminal 110, which can be a wireless network card, etc., for uploading the extracted biometric information to the test security terminal 110 and receiving the matching result sent by the test security terminal 110. The control module is a module that drives the access switch according to the received matching result, for example, the locking and unlocking of a metal door can be realized by controlling the on-off of an electromagnet.

[0081] A relational database can be established as the permission database, a unique ID is assigned to each person as the primary key of the permission data table, and the permission information of different persons is entered into the permission data table; a biometric information data table is established, the person ID is taken as the foreign key, and the biometric information of the corresponding person is entered, thereby establishing the association between the permission data table and the biometric information data table. Thus, the biometric information can be input, the person ID corresponding to the biometric information is queried in the permission database, and then the permission information of the person is queried according to the person ID.

[0082] The permission database can be stored in the test security terminal 110. After receiving the biometric information uploaded by the access control device 140, the person and permission information corresponding to the biometric information are queried. If there is no person corresponding to the biometric information, or the person corresponding to the biometric information does not have the permission to enter the power test area, it is determined that the matching fails, and the data such as the time, place, original biological data, and biometric information of this query can be stored in the system log. If there is a person corresponding to the biometric information, and the person has the permission to enter the power test area, it is determined that the matching is successful. In the case of successful matching, the result of successful matching can be sent to the access control device 140 through the communication interface, so that the access control device 140 opens the access control in response to the matching result; at the same time, an activation instruction is sent to the transmitting end 121 of the laser electronic fence 120.

[0083] After the transmitting end 121 of the laser electronic fence 120 receives the activation instruction sent by the test security terminal 110, the light source and the modulation excitation power supply are started, and the light signal is sent to the receiving end 122 of the laser electronic fence 120 to form the laser fence light curtain.

[0084] In this embodiment, by setting the access control device 140 at the entrance of the power test area, the access control is opened in the case that the biometric information of the person and the permission database are successfully matched, which can reduce the situation that unauthorized personnel enter the power test area to interfere with the test; the laser electronic fence 120 is automatically activated at the same time that the access control is opened, which can reduce the security risks caused by the delay of manually activating the laser electronic fence 120.

[0085] In some embodiments, the safety protection system further comprises a behavior recognition camera 150 arranged in a target monitoring range in the power test area; The behavior recognition camera 150 is configured to recognize behavior information of a person located in the target monitoring range, and send the behavior information to the test security terminal 110 in the case that the behavior information is a target dangerous behavior; The test security terminal 110 is configured to generate a control instruction corresponding to the behavior information.

[0086] In the embodiment of the present application, the target monitoring range is a range in the power test area that needs to be monitored. The user can pre-set the target monitoring range of the power test area and deploy the behavior recognition camera 150 according to the layout of the power test site, the deployment position of the target device 130, and the like. For example, the user can set the area where the target device 130 is located as the target monitoring area, and deploy several behavior recognition cameras 150 near the target device 130, and make the monitoring range of each behavior recognition camera 150 cover the target monitoring area.

[0087] The behavior recognition camera is a kind of intelligent monitoring device, which can recognize the behavior of the personnel in the camera picture range in real time by using computer vision and artificial intelligence technology to analyze the image data collected by the camera. Behavior recognition is a kind of computer vision technology, which extracts the posture features of the person in each video frame of the video data by using a deep learning algorithm, and then analyzes the continuous changes of the posture features of the person in the continuous video frames to obtain the behavior information of the person in the video data. The behavior information obtained by behavior recognition can be a feature vector describing the behavior characteristics of the person, or a behavior category classified according to the feature vector, such as “reaching out to touch the device” and “approaching the device”.

[0088] The image data in the target monitoring range can be collected by using visible light cameras, thermal imaging cameras, laser radar cameras, and the like; the edge computing device deployed with the deep learning-based behavior recognition model is used to analyze the image data collected by the camera and extract the behavior information of the personnel in the target monitoring range; the communication between the behavior recognition camera 150 and the test security terminal 110 is established through optical fibers, wireless network cards, and the like, and the recognized behavior information is sent to the test security terminal 110.

[0089] After receiving the behavior information sent by the behavior recognition camera 150, the test security terminal 110 generates a control instruction corresponding to the behavior information. The control instruction corresponding to the behavior information can be determined according to the response rules pre-set by the user. For example, the user can set two response rules “reaching out to touch the device-power off” and “approaching the device-alarm”, and when the received behavior information is “reaching out to touch the device”, the control instruction “power off” is generated, and when the received behavior information is “approaching the device”, the control instruction “alarm” is generated.

[0090] In this embodiment, by using the behavior recognition camera 150 to recognize the behavior information of the personnel located in the target monitoring range, in the case of recognizing the target dangerous behavior, the behavior information is sent to the test security terminal 110 and the corresponding control instruction is automatically generated, which can reduce the safety hidden danger caused by the response lag of manual supervision, thereby improving the safety protection level of the power test site.

[0091] In some embodiments, the target monitoring range includes the high-voltage test area and the ordinary test area within the power test area; The test security terminal 110 is also used to send a power-off command to the target device 130 and generate a second alarm message when the behavior information is touching the equipment in the high-voltage test area; and to generate a third alarm message when the behavior information is being in the target period of the ordinary test area.

[0092] In this embodiment, the high-voltage test area is a high-risk area where high-voltage test equipment is deployed, while the ordinary test area is a low-risk area. Users can pre-divide the high-voltage test area and the ordinary test area based on the deployment of the test equipment. For example, the location of high-voltage equipment such as high-voltage transformers can be designated as the high-voltage test area, and the buffer zone surrounding the test equipment can be designated as the ordinary test area. Behavior recognition cameras 150 are installed at the corresponding locations, and the behavior recognition algorithm is adjusted so that the obtained behavior information includes data such as behavior type, behavior location, and duration.

[0093] After receiving behavioral information from the behavior recognition camera 150, the test security terminal 110 checks the content of the behavioral information. When the behavioral information is "touching equipment in the high-voltage test area," the control command is to send a power-off command to the target equipment 130 and generate a second alarm message; the second alarm message can be an emergency alarm message, such as playing an alarm sound through a speaker. When the behavioral information is "being in the normal test area for the target duration," the control command is to generate a third alarm message; the third alarm message can be a warning message, such as playing a "please stay away from the equipment" prompt through a speaker; the target duration is a time value that can be preset by the user. Alternatively, if the behavioral information is "being in the normal test area for more than the target duration," the control command can be escalated to a power-off command.

[0094] In this embodiment, by setting different protection modes for different types of test areas, a power-off command is sent to the target device 130 when the behavior information indicates touching equipment in the high-voltage test area and the degree of danger is high. This can reduce the number of power outages and thus protect the target device 130.

[0095] In some embodiments, a fusion analysis tool can also be deployed in the test security terminal 110 to integrate and analyze data from devices such as the laser electronic fence 120, target device 130, access control device 140, and behavior recognition camera 150 in the power test area, and generate control commands based on the fusion analysis results. Fusion analysis is a data processing technology that improves the accuracy and reliability of analysis results by analyzing data from multiple data sources and fusing them according to a certain algorithm. Time series analysis engines, rule engines, etc., can be used as fusion analysis tools.

[0096] For example, the laser electronic fence 120 and the data uploaded by the behavior recognition camera 150 can be accessed to the rule engine, when the laser fence sends a shielding alarm signal and the behavior recognition camera recognizes an intrusion behavior, the generated control instruction is a power-off instruction.

[0097] In some embodiments, a statistical analysis tool can also be deployed in the test security terminal 110 to analyze the operation data, alarm data, log data, etc. of each device in the power test area using a deep learning algorithm, generate an analysis report for optimizing the security policy and personnel training. Thus, scientific basis can be provided for security management decisions, and the safety and automation management level of the power test site can be improved.

[0098] The embodiments of the present application also provide a safety protection method based on an intelligent laser electronic fence, applied to a test security terminal. As shown in Figure 3 The safety protection method based on the intelligent laser electronic fence can include steps 310, 320 and 330.

The application embodiment can reduce the safety hidden danger caused by the response lag of manual supervision, thereby improving the safety protection level of the power test site, by automatically generating the alarm information in the case of sending the shielding alarm signal of the laser electronic fence, and automatically sending the power-off instruction to the target device when the test state of the target device is being tested.

[0102] In some embodiments, the safety protection method based on the intelligent laser electronic fence further comprises: Receiving personnel biological feature information; wherein the personnel biological feature information is collected and sent by the access control device, and the access control device is arranged at the entrance of the power test area; Matching the personnel biological feature information with the permission database, in the case of successful matching, opening the access control, and sending the activation instruction to the transmitting end to activate the transmitting end to transmit the optical signal to the receiving end to form the laser fence light curtain; the permission database stores the mapping relationship between different personnel biological feature information and permissions.

[0103] In this embodiment, by arranging the access control device at the entrance of the power test area, opening the access control in the case of successful matching of the personnel biological feature information with the permission database, the situation that the personnel without permission enter the power test area to interfere with the test can be reduced; the laser electronic fence is automatically activated at the same time of opening the access control, the safety hidden danger caused by the manual activation of the laser electronic fence not being timely can be reduced.

[0104] In some embodiments, the safety protection method based on the intelligent laser electronic fence further comprises: Receiving the behavior information of the personnel in the target monitoring range; wherein the behavior information is collected by the behavior recognition camera and is sent in the case of the target dangerous behavior, and the behavior recognition camera is arranged in the target monitoring range in the power test area; Generating the control instruction corresponding to the behavior information.

[0105] In the embodiment, the behavior information of the personnel located in the target monitoring range is recognized by using the behavior recognition camera, and in the case that a target dangerous behavior is recognized, the behavior information is sent to the test security terminal and a corresponding control instruction is automatically generated, which can reduce the security risks caused by the response lag of manual supervision, thereby improving the safety protection level of the power test site.

[0106] In some embodiments, the target monitoring range includes a high-voltage test area and a general test area in the power test area. The control instruction corresponding to the behavior information includes: In the case that the behavior information is touching the equipment in the high-voltage test area, the control instruction is to send a power-off instruction to the target equipment and generate second alarm information. In the case that the behavior information is in the target duration in the general test area, the control instruction is to generate third alarm information.

[0107] In the embodiment, different protection modes are set for different types of test areas, and in the case that the behavior information is touching the equipment in the high-voltage test area and the danger level is high, a power-off instruction is sent to the target equipment, which can reduce the number of power-off times and protect the target equipment.

[0109] When the test personnel tries to unlock the access control, the access control camera collects the facial feature information of the test personnel, uploads the facial feature information to the test security terminal, and the test security terminal matches the facial feature information with the permission database. In the case of successful matching, the access control is unlocked, and the laser electronic fence is activated, and the test personnel enters the test room.

[0110] If the test personnel pass through the laser electronic fence while shielding the visible light signal and the invisible light signal, the laser electronic fence sends a shielding alarm signal to the test security terminal. The test security terminal generates first alarm information and queries the test state of the target device. If the test has not been performed, the shielding event is recorded and prompt information is generated. If the test is being performed, a power-off instruction is sent to the target device.

[0111] The behavior recognition camera continuously collects image data of the high-voltage test area and the ordinary test area and recognizes test personnel behavior data. If it is identified that the test personnel mistakenly enter the high-voltage test area and touch the device with their hands, the test security terminal sends a power-off instruction to the target device and plays a warning prompt sound. If it is identified that the test personnel stay in the ordinary test area, a voice warning sound is played. If it is identified that the test personnel stay in the ordinary test area for more than a preset time, a power-off instruction is sent to the target device.
