Description

Technical Field

[0001] The present application relates to the technical field of coal mine video surveillance, and in particular to a security method for an open-air coal storage yard in a coal mine, a security device for an open-air coal storage yard in a coal mine, a computer program product, and a security system for an open-air coal storage yard in a coal mine. Background Art

[0002] Due to the constraints of the environment and conditions, effective electronic fences are generally not installed in open-pit coal storage yards in coal mines. Due to the large area of ​​the coal storage yard and the limited number of security personnel, they are unable to take care of all the sites. Materials are often lost, and they cannot be traced afterwards. There is a lack of effective security technical defense measures. At present, security prevention mainly relies on installing cameras at the entrances and exits and conducting video surveillance in the control room. Security personnel are required to keep a close eye on the monitoring screen at all times. When security personnel find abnormal situations, they use loudspeakers to warn illegal intruders. The level of intelligence is low and abnormal situations cannot be identified. If some key information is missed, the only way is to retrieve the video within the approximate time period from the hard disk recorder afterwards, which is labor-intensive and inefficient.

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] The existing security measures in coal yards are relatively backward. Many coal storage yards still use manual inspections or install cameras around key areas, relying on security personnel to monitor the display screens in real time to achieve security purposes. Once the security personnel are not paying attention, it is easy to miss certain key information. When abnormal situations are discovered and surveillance footage needs to be retrieved, they can only be played back one by one, and useful information cannot be found quickly, which is inefficient.

[0031] As introduced in the background technology, there are problems in the prior art of manual inspection of open-air coal storage yards in coal mines and relatively low security efficiency. To solve the above problems, the embodiments of the present application provide a security method for an open-air coal storage yard in a coal mine, a security device for an open-air coal storage yard in a coal mine, a computer program product and a security system for an open-air coal storage yard in a coal mine.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a mobile terminal of a security method for an open-pit coal storage yard of a coal mine according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0034] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the display method of device information in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, the above method is implemented. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of the above-mentioned network include but are not limited to the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof. The transmission device 106 is used to receive or send data via a network. The above-mentioned specific examples of the network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0035] In this embodiment, a security method for an open-pit coal storage yard in a coal mine is provided, which runs on a mobile terminal, a computer terminal or a similar computing device. 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.

[0036] Figure 2 FIG. 1 is a flow chart of a security method for an open-pit coal storage yard in a coal mine according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0037] Step S201, obtaining a video of an open-pit coal storage yard of a coal mine;

[0038] Specifically, the video of the open-air coal storage yard of the coal mine can be obtained. Specifically, a video acquisition device can be installed in the open-air coal storage yard of the coal mine to collect the video of the open-air coal storage yard of the coal mine. Of course, the video acquisition device can be a camera or any other feasible device.

[0039] Step S202, extracting the security area in the video, wherein the security area is a pre-demarcated area in the open-pit coal storage yard of the coal mine that needs to be protected;

[0040] Specifically, areas that need to be defended are pre-demarcated in the open-air coal storage yard of the coal mine, such as the material stacking area, the area with clean coal, or the area where coal mining equipment is docked. These areas can be extracted from the video of the open-air coal storage yard of the coal mine to facilitate security monitoring of important areas of the open-air coal storage yard of the coal mine.

[0041] Step S203: when an illegal object appears in the security area, a first alarm message is generated, wherein the illegal object is an object that has no authority to enter the open-pit coal storage yard of the coal mine.

[0042] Specifically, if an illegal object appears in the security area of ​​the open-air coal storage yard of a coal mine, that is, an unauthorized object enters the security area of ​​the open-air coal storage yard of a coal mine, a first alarm message can be generated at this time to remind the staff that there is an illegal intrusion into the open-air coal storage yard of the coal mine. The illegal object can be an illegal person or illegal equipment.

[0043] Through this embodiment, security areas are pre-set in the open-air coal storage yard of the coal mine. By performing video surveillance on the open-air coal storage yard of the coal mine, if an illegal object breaks into the security area, an alarm can be sounded in time to prompt the security personnel, thereby realizing automated security monitoring and improving the security efficiency of the open-air coal storage yard of the coal mine.

[0044] During the specific implementation process, before extracting the security area in the above video, the above method also includes the following steps: obtaining all areas in the above open-pit coal storage yard of the coal mine; if there is material accumulation in any of the above areas and / or the above areas are currently in the working time period, determining the above areas as the above security areas.

[0045] In this solution, you can customize the areas in the open-pit coal storage yard of a coal mine that require security. For example, if there are piled materials, in order to prevent illegal objects from stealing materials, the area where the materials are piled in the open-pit coal storage yard of the coal mine can be used as a security area. And when a certain area in the open-pit coal storage yard of a coal mine is working, in order to prevent illegal objects from breaking into and affecting normal work, the area where the materials are piled in the open-pit coal storage yard of the coal mine can be used as a security area. In this way, the setting of the placement area can be customized, and customized security monitoring of the open-pit coal storage yard of a coal mine can be further realized.

[0046] Specifically, a defense area is divided for each coal yard entrance and exit on the video surveillance interface, and the surrounding materials are divided into areas in the sites where different materials are piled, so that different material piles in the area can be zoned for defense.

[0047] Specifically, the system can be manually armed by staff, or automatically armed by setting a time period, or the system can be armed with one click for each area's stockpile based on the different sales times of the stockpiles in each coal storage yard.

[0048] In some embodiments, after extracting the security area in the above video, the above method also includes the following steps: obtaining a disarming demand, wherein the above disarming demand is a demand for no longer deploying defenses in the above security area and disarming the above security area; disarming the above security area and converting the above security area into an ordinary above area.

[0049] In this solution, when there is no need to provide security for the area in the open-air coal storage yard of a coal mine, the area in the open-air coal storage yard of a coal mine can also be disarmed. When the area in the open-air coal storage yard of a coal mine is not a security area, if an illegal object appears in the open-air coal storage yard of a coal mine, no alarm may be given, or other customized situations may be used to give an alarm, thereby further realizing automated disarming monitoring.

[0050] Specifically, the staff can flexibly disarm each stockpile area according to the sales time or defense needs of each coal storage yard. After the disarming, people and vehicles can freely enter and exit the area, and no alarm will be triggered after the area crosses the boundary. The cross-border alarm area is divided. During the non-sales time period, the system is in a defense state. If an area crosses the boundary and is triggered, the alarm system will immediately pop up the video interface of the area, and play voice and sound and light alarms in the area to warn illegal intruders on the scene.

[0051] During the specific implementation process, after extracting the security area in the above-mentioned video, the above-mentioned method also includes the following steps: when an object appears in the above-mentioned security area, extracting the facial information of the above-mentioned object; obtaining a target database, wherein the above-mentioned target database includes the legal facial information of multiple authorized legal objects; when the above-mentioned target database includes the above-mentioned facial information of the above-mentioned object, determining that the above-mentioned object is the above-mentioned legal object; when the above-mentioned target database does not include the above-mentioned facial information of the above-mentioned object, determining that the above-mentioned object is the above-mentioned illegal object.

[0052] In this solution, the legal facial information of legal objects with multiple permissions is pre-stored in the target database. In this way, if an object is detected entering the security area, it can be determined whether the object is a legal object in the target database or an illegal object through face recognition and matching. This allows for simple and fast custom identification without the need for manual judgment.

[0053] Specifically, this solution adopts automated intelligent control technology, and uses cameras with front-end area detection and alarm output functions to monitor key areas, solving the problem of manual inspections required for coal yard security. A WISCADA video plug-in script has been developed so that the video surveillance screen can be displayed normally in the upper software. When there is illegal intrusion by personnel and vehicles, the AI ​​camera linkage alarm transmits the signal to the upper software through the PLC, pops up the on-site monitoring screen, captures the picture and stores the video, and reminds the security personnel, which can effectively solve the problem of security personnel needing to monitor the display screen in real time. If you want to view the on-site screen at the time of the alarm later, click the alarm information in the system to pop up the surveillance video at that time, which greatly saves the time of retrieving the monitoring and improves the safety and modern management level of coal production to a certain extent.

[0054] Specifically, this security linkage system uses WISCADA as the upper software, and develops a video script plug-in that combines video surveillance and upper software WISCADA, so that the monitoring screen can be compatible with the software, and all monitoring video screens can be displayed on the operating software interface at the same time, and any screen can be called at any time. The key monitoring area is divided at the entrance and exit of the coal storage yard in the monitoring screen, and the AI ​​super brain regional intrusion event capture function is combined. When there is an illegal intrusion of personnel or vehicles, a set of wireless alarms is established in combination with the Internet of Things technology. Through a variety of technologies including TCP / IP network transmission protocol, multimedia control technology, and programmable control technology, the scene screen pops up in the upper software after the regional intrusion, and the illegal intrusion picture is captured. The upper software VB script is developed to realize the hierarchical control and classification query of event alarm information. Finally, the Linux-RT operating system is deployed in the WIHMIBOX enhanced 4G multi-protocol data acquisition terminal hardware, and the WISCADA service is deployed in the hardware. The WISCADA embedded environment is used for development, which integrates Python IDE. A variety of functions can be customized and developed. This time, the integrated Python IEC and SDK are used for interaction to realize picture capture, video stream interception and storage. Clicking the alarm record can read the video of 10 seconds before and after the corresponding time point of the hard disk recorder, which greatly saves the time for subsequent monitoring. In order to extend the storage time, the SD card function is added to the hardware, which can support external storage expansion of up to 64GB for accessing video streams after a fault. If a vehicle is found to have entered the security area, it can be displayed on the display interface.

[0055] In some embodiments, after generating the first alarm information, the method further includes the following steps: according to the first alarm information, controlling the alarm device to alarm, wherein the alarm device is located in the open-pit coal storage yard of the coal mine; according to the first alarm information, displaying the video and the image of the illegal object on the display device.

[0056] In this scheme, when the first alarm information is generated, the alarm device can be controlled to sound an alarm, which can be an audible and visual alarm to warn illegal objects on the scene. At the same time, the video and the image of the illegal object are displayed on the display device, so that the staff can check the situation of the open-pit coal storage yard of the coal mine in time.

[0057] Specifically, this plan discloses a coal yard security linkage alarm system, which is mainly composed of a central control system and a front-end perimeter system. The central control system includes an industrial control host, a liquid crystal display, a voice alarm player, a core switch, a photoelectric converter, etc. The front-end perimeter system protection consists of an active infrared detector ABH-300, a UPS voltage-stabilized power supply, a convergence layer switch, an audible and visual alarm, a loop broadcasting speaker, etc.

[0058] Specifically, cameras and sound and light alarms with front-end area detection alarm output functions are installed around and inside the coal storage yard that has no physical fences and multiple entrances and exits. Security personnel can check the on-site situation in the control room at any time. The use of this set of monitoring equipment can completely replace the previous manual inspection method of security personnel.

[0059] During the specific implementation process, after extracting the security area in the above-mentioned video, the above-mentioned method also includes the following steps: obtaining audio in the above-mentioned open-air coal storage yard of the coal mine; performing voice recognition on the above-mentioned audio to obtain a voice recognition result, wherein the above-mentioned voice recognition result is used to characterize whether there is an object that is about to break into the above-mentioned security area of ​​the above-mentioned open-air coal storage yard of the coal mine; when the above-mentioned voice recognition result characterizes that there is an object that is about to break into the above-mentioned security area of ​​the above-mentioned open-air coal storage yard of the coal mine, a second alarm information is generated.

[0060] In this solution, if the illegal object is in the blind spot of the video, voice recognition can be performed based on the audio in the open-air coal storage yard of the coal mine. If the voice recognition result indicates that the object is about to break into the security area, an alarm can be issued. This can prevent the illegal object from evading surveillance and from breaking into the security area through the blind spot, further improving the security efficiency of the open-air coal storage yard of the coal mine.

[0061] Specifically, it is necessary to deploy audio acquisition equipment, such as microphones or audio sensors, in the security area of ​​the open-pit coal storage yard of the coal mine to capture the sound signals on the scene. These devices should have the characteristics of high sensitivity and strong noise resistance to ensure that the sound information on the scene can be accurately captured.

[0062] The collected audio signals often contain various noises and interferences, so preprocessing is required to improve the accuracy of speech recognition. The preprocessing steps include:

[0063] Noise reduction processing: Remove background noise through filters and other means to improve the clarity of speech signals.

[0064] Pre-emphasis: Enhances the energy of the high-frequency part to make the speech signal flatter in the spectrum, which is beneficial for subsequent feature extraction.

[0065] Framing: Split the continuous audio signal into multiple short-time sequences, each of which is called a frame. The purpose of framing is to convert the speech signal into a series of short time segments that are easy to process.

[0066] Feature extraction: Extract parameters that can characterize speech characteristics from each frame, such as Mel-frequency cepstral coefficients (MFCC). These features will be used for subsequent speech recognition.

[0067] In order to achieve accurate recognition of audio signals, a speech recognition model needs to be trained. Collect speech data from the open-pit coal storage yard of the coal mine, including sounds under normal circumstances, sounds of intruders, etc. These data should be labeled for subsequent training and testing. Select a suitable speech recognition model, such as hidden Markov model (HMM), deep learning model (such as convolutional neural network CNN, recurrent neural network RNN ​​and its variants), etc. These models have powerful speech feature extraction and pattern recognition capabilities. Use the prepared speech data to train the model so that it can learn the mapping relationship between speech signals and corresponding texts. During the training process, the parameters of the model need to be continuously adjusted to improve the accuracy of recognition.

[0068] After the model training is completed, the collected audio signals can be recognized. The collected audio signals are preprocessed and feature extracted to obtain the same feature representation as during training. The extracted features are matched with the trained speech recognition model to find the most likely text output. Based on the recognized text content, it is determined whether there is an object trying to break into the security area of ​​the open-pit coal storage yard of the coal mine. For example, if keywords such as "break in" and "enter" are recognized, it can be considered that an object is trying to break into the security area.

[0069] In some embodiments, after extracting the security area in the above-mentioned video, the above-mentioned method also includes the following steps: obtaining detection information, wherein the above-mentioned detection information is used to characterize whether the electronic fence of the above-mentioned open-air coal storage yard of the coal mine has been invaded and / or damaged; when the above-mentioned detection information characterizes that the electronic fence of the above-mentioned open-air coal storage yard of the coal mine has been invaded and / or damaged, generating a third alarm information.

[0070] In this solution, an electronic fence is set in the open-air coal storage yard of the coal mine. If the electronic fence of the open-air coal storage yard of the coal mine is detected to be invaded and / or damaged, an alarm can be issued, which can further improve the security efficiency of the open-air coal storage yard of the coal mine.

[0071] Specifically, first check whether all the equipment of the electronic fence system is intact, including power supply, controller, sensor, etc. Make sure that the electronic fence system has been properly started and is in working condition.

[0072] By monitoring the input voltage and output current of the electronic fence, it is possible to determine whether the circuit is normal. Any abnormal voltage or current fluctuations may indicate that the fence is damaged or someone is trying to break in illegally. Once an abnormality is detected, the system should immediately sound an alarm and display the fault location.

[0073] Cameras are set up around the electronic fence to achieve real-time monitoring of the situation inside and outside the fence. When the camera captures someone trying to destroy the fence or break into the fence, an alarm should be triggered immediately and the real-time picture should be transmitted to the monitoring center.

[0074] The infrared detector can detect people or animals entering the set infrared range, and once triggered, an alarm will be sounded immediately.

[0075] The vibration sensor can sense the vibration of the fence. Whether it is caused by someone trying to destroy the fence or by animals passing through the fence, it can monitor and trigger an alarm in time.

[0076] Sound recognition technology can be used to detect abnormal sounds occurring inside a fence, such as the sound of someone destroying the fence, the sound of someone climbing over the fence, etc.

[0077] By monitoring the grounding condition of the electronic fence, it can be determined whether the fence is damaged. When there is a problem with the grounding, the electronic fence will immediately alarm.

[0078] The temperature monitoring device can detect whether there are obvious temperature changes on the electronic fence, such as abnormally high or low temperatures, and issue an alarm in time.

[0079] Specifically, in response to the problem that existing security measures require real-time human monitoring, this solution has developed a system that can realize intelligent alarm after people and vehicles enter the defense zone through real-time analysis by front-end cameras; according to the different sales periods of different coal yards, PLC control technology is used to realize the flexible change of the defense and disarming time of different coal yards, and the function of manual and automatic setting.

[0080] 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 security method for an open-pit coal storage yard in a coal mine of the present application will be described in detail below in conjunction with specific embodiments.

[0081] This embodiment relates to a specific security method for an open-pit coal storage yard in a coal mine, and the embodiments are as follows:

[0082] The alarm control program of the security system of a coal storage yard is divided into: manual control system, automatic control system and stop system.

[0083] (1) When the alarm system is put into operation, V500.1=0, then the M10.0 coil is not connected, that is, M10.0=0, and the M10.0 normally closed point is connected. When the system is in manual state, the corresponding point V500.0 is 0, that is, the V500.0 normally closed point is connected. At this time, when the out-of-bounds alarm input signal is input (the alarm camera outputs an alarm signal) (that is, when I0.0=1), the alarm signal is connected after a 1S delay (to prevent the alarm signal from being triggered by mistake), then V0.0 is connected to output the coal storage yard out-of-bounds alarm. Figure 3 A schematic diagram of a first flowchart is shown; Figure 4 A schematic diagram of a second flowchart is shown; Figure 5 A schematic diagram of a third flowchart is shown;

[0084] (2) When the alarm system is set to stop running and V500.0=1, the M10.0 coil is connected, that is, M10.0=1, and the normally closed point of M10.0 is disconnected. That is, when the system is in manual state, the corresponding point V500.0 is 0, that is, the normally closed point of V500.0 is connected. Even if there is an out-of-bounds alarm input signal (that is, when I0.0=1), the alarm signal is connected after a 1S delay (to prevent the alarm signal from being triggered by mistake), and the camera triggers the coal storage yard out-of-bounds alarm output condition is not met, that is, V0.0 is not connected, and no alarm signal is output.

[0085] (3) When the system is in automatic state, the alarm time period can be set. At this time, the time of the PLC system is read through the program reading time instruction.

[0087] The embodiment of the present application also provides a security device for an open-air coal storage yard in a coal mine. It should be noted that the security device for an open-air coal storage yard in a coal mine in the embodiment of the present application can be used to execute the security method for an open-air coal storage yard in a coal mine 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 explained will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware for 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.

[0088] The following is an introduction to the security device for an open-pit coal storage yard in a coal mine provided in an embodiment of the present application.

[0089] Fig. 9 1 is a structural block diagram of a security device for an open-pit coal storage yard of a coal mine according to an embodiment of the present application. Fig. 9 As shown, the device comprises:

[0090] A first acquisition unit 10 is used to acquire a video of an open-air coal storage yard of a coal mine;

[0091] A first extraction unit 20 is used to extract a security area in the video, wherein the security area is a pre-demarcated area in the open-pit coal storage yard of the coal mine that needs to be protected;

[0092] The first generating unit 30 is used to generate a first alarm message when an illegal object appears in the security area, wherein the illegal object is an object that has no authority to enter the open-air coal storage yard of the coal mine.

[0093] Through this embodiment, security areas are pre-set in the open-air coal storage yard of the coal mine. By performing video surveillance on the open-air coal storage yard of the coal mine, if an illegal object breaks into the security area, an alarm can be sounded in time to prompt the security personnel, thereby realizing automated security monitoring and improving the security efficiency of the open-air coal storage yard of the coal mine.

[0094] During the specific implementation process, the above-mentioned device also includes a second acquisition unit and a first determination unit. The second acquisition unit is used to acquire all areas in the above-mentioned open-pit coal storage yard of the coal mine before extracting the security area in the above-mentioned video; the first determination unit is used to determine that the above-mentioned area is the above-mentioned security area when there is material accumulation in any of the above-mentioned areas and / or the above-mentioned area is currently in the working time period.

[0095] In this solution, you can customize the areas in the open-pit coal storage yard of a coal mine that require security. For example, if there are piled materials, in order to prevent illegal objects from stealing materials, the area where the materials are piled in the open-pit coal storage yard of the coal mine can be used as a security area. And when a certain area in the open-pit coal storage yard of a coal mine is working, in order to prevent illegal objects from breaking into and affecting normal work, the area where the materials are piled in the open-pit coal storage yard of the coal mine can be used as a security area. In this way, the setting of the placement area can be customized, and customized security monitoring of the open-pit coal storage yard of a coal mine can be further realized.

[0096] In some embodiments, the above-mentioned device also includes a third acquisition unit and a processing unit, and the third acquisition unit is used to obtain a disarming demand after extracting the security area in the above-mentioned video, wherein the above-mentioned disarming demand is a demand for no longer deploying the above-mentioned security area and disarming the above-mentioned security area; the processing unit is used to disarm the above-mentioned security area and convert the above-mentioned security area into an ordinary above-mentioned area.

[0097] In this solution, when there is no need to provide security for the area in the open-air coal storage yard of a coal mine, the area in the open-air coal storage yard of a coal mine can also be disarmed. When the area in the open-air coal storage yard of a coal mine is not a security area, if an illegal object appears in the open-air coal storage yard of a coal mine, no alarm may be given, or other customized situations may be used to give an alarm, thereby further realizing automated disarming monitoring.

[0098] During the specific implementation process, the above-mentioned device also includes a second extraction unit, a fourth acquisition unit, a second determination unit and a third determination unit. The second extraction unit is used to extract the facial information of the above-mentioned object when the object appears in the above-mentioned security area after extracting the security area in the above-mentioned video; the fourth acquisition unit is used to acquire a target database, wherein the above-mentioned target database includes legal facial information of multiple authorized legal objects; the second determination unit is used to determine that the above-mentioned object is the above-mentioned legal object when the above-mentioned facial information of the above-mentioned object is included in the above-mentioned target database; the third determination unit is used to determine that the above-mentioned object is the above-mentioned illegal object when the above-mentioned facial information of the above-mentioned object is not included in the above-mentioned target database.

[0099] In this solution, the legal facial information of legal objects with multiple permissions is pre-stored in the target database. In this way, if an object is detected entering the security area, it can be determined whether the object is a legal object in the target database or an illegal object through face recognition and matching. This allows for simple and fast custom identification without the need for manual judgment.

[0100] In some embodiments, the above-mentioned device also includes a control unit and a display unit. The control unit is used to control the alarm device to alarm according to the first alarm information after generating the first alarm information, wherein the above-mentioned alarm device is located in the open-air coal storage yard of the above-mentioned coal mine; the display unit is used to display the above-mentioned video and the image of the above-mentioned illegal object in the display device according to the above-mentioned first alarm information.

[0101] In this scheme, when the first alarm information is generated, the alarm device can be controlled to sound an alarm, which can be an audible and visual alarm to warn illegal objects on the scene. At the same time, the video and the image of the illegal object are displayed on the display device, so that the staff can check the situation of the open-pit coal storage yard of the coal mine in time.

[0102] During the specific implementation process, the above-mentioned device also includes a fifth acquisition unit, an identification unit and a second generation unit. The fifth acquisition unit is used to obtain the audio in the open-air coal storage yard of the above-mentioned coal mine after extracting the security area in the above-mentioned video; the identification unit is used to perform voice recognition on the above-mentioned audio to obtain a voice recognition result, wherein the above-mentioned voice recognition result is used to characterize whether there is an object about to break into the above-mentioned security area of ​​the above-mentioned open-air coal storage yard of the above-mentioned coal mine; the second generation unit is used to generate a second alarm information when the above-mentioned voice recognition result characterizes that there is an object about to break into the above-mentioned security area of ​​the above-mentioned open-air coal storage yard of the above-mentioned coal mine.

[0103] In this solution, if the illegal object is in the blind spot of the video, voice recognition can be performed based on the audio in the open-air coal storage yard of the coal mine. If the voice recognition result indicates that the object is about to break into the security area, an alarm can be issued. This can prevent the illegal object from evading surveillance and from breaking into the security area through the blind spot, further improving the security efficiency of the open-air coal storage yard of the coal mine.

[0104] In some embodiments, the above-mentioned device also includes a sixth acquisition unit and a third generation unit, the sixth acquisition unit is used to obtain detection information after extracting the security area in the above-mentioned video, wherein the above-mentioned detection information is used to indicate whether the electronic fence of the above-mentioned coal mine open-air coal storage yard has been invaded and / or damaged; the third generation unit is used to generate third alarm information when the above-mentioned detection information indicates that the electronic fence of the above-mentioned coal mine open-air coal storage yard has been invaded and / or damaged.

[0105] In this solution, an electronic fence is set in the open-air coal storage yard of the coal mine. If the electronic fence of the open-air coal storage yard of the coal mine is detected to be invaded and / or damaged, an alarm can be issued, which can further improve the security efficiency of the open-air coal storage yard of the coal mine.
