Area safety protection methods and systems for subways

Abstract

This application discloses a method and system for area security protection in subways. The solution uses a control device to output an opening control signal to control an intrusion detection device to activate when the detection opening conditions are met. At this time, the intrusion detection device forms a detection medium at a preset position, thereby defining the area boundary, i.e., dividing the protected area into an unprotected area. The intrusion detection device detects whether an object is located at the area boundary and outputs an alarm signal when an object is detected. This can replace existing physical doors and monitor whether personnel are entering or exiting protected areas in operating locations such as shopping malls, supermarkets, libraries, stadiums, and subway stations. The location of the intrusion detection device can be flexibly set, and the shape and size of the detection medium can also be changed according to needs, providing high security flexibility while solving the problem of high maintenance and installation costs associated with physical doors.

[0018] The video management device captures an image of the surrounding environment at the boundary of the area at the corresponding time based on the alarm signal, and sends the image of the surrounding environment to the control device.

[0019] In one exemplary embodiment, before outputting the enable control signal to the intrusion detection device, the method further includes:

[0020] An audio playback control signal is sent to the audio playback device, which then plays a prompt audio message to indicate that the intrusion detection device is about to activate.

[0021] In one exemplary embodiment, the step of forming a detection medium at a preset location by the intrusion detection device to define the area boundary includes:

[0023] According to one aspect of the embodiments of this application, a regional security protection system is disclosed, including an intrusion detection device and a control device. The intrusion detection device is used to form a detection medium at a preset position to define a regional boundary. The intrusion detection device is capable of detecting whether an object is located at the regional boundary and outputting an alarm signal when an object is detected at the regional boundary.

[0045] The exemplary embodiments will now be described in detail. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the summary of the invention.

[0046] An exemplary embodiment of this application provides a regional security protection method and system, which is applicable to operating venues such as shopping malls, supermarkets, libraries, stadiums, and subway stations. It can replace existing physical doors to provide regional security protection for operating venues when regional security protection is required.

[0047] Figure 1 A block diagram of a regional security protection system that can implement the regional security protection method of the exemplary embodiments of this application is shown. Figure 1As shown, the area security protection system 100 may include an intrusion detection device 101 and a control device 102. The intrusion detection device 101 and the control device 102 are communicatively connected to realize information interaction between the intrusion detection device 101 and the control device 102, thereby realizing security protection of the operating site.

[0048] Specifically, the intrusion detection device 101 and the control device 102 can be connected via a wired connection, such as via RS485 bus, USB cable, Ethernet, etc. Alternatively, the intrusion detection device 101 and the control device 102 can be connected wirelessly, such as via Wi-Fi, Bluetooth, ZigBee, LoRa (Long Range Radio), 4G communication, 5G communication, etc.

[0049] Understandably, the intrusion detection device 101 can be any device capable of forming a specific detection medium. The detection medium can be, for example, an optical signal and / or an acoustic signal and / or an electromagnetic wave signal, or it can be, for example, a water curtain. For example, the intrusion detection device 101 is an infrared photoelectric protection device capable of forming a detection light curtain, that is, the detection medium is an optical signal; as another example, the intrusion detection device 101 is a security scanning radar capable of forming an acoustic wave, that is, the detection medium is an acoustic signal.

[0050] Understandably, the control device 102 can be any electronic device with data interaction and data processing capabilities, such as a tablet computer, desktop computer, etc.

[0051] It should be noted that the area security protection system 100 may include one intrusion detection device 101 and one control device 102, or it may include multiple intrusion detection devices 101 and multiple control devices 102. In addition to including the intrusion detection device 101 and the control device 102, the area security protection system 100 may further include other devices, such as camera devices, audio playback devices, video management devices, etc.

[0052] The regional security protection method and regional security protection system of this application will be described in detail below through the following embodiments.

[0053] First refer to Figure 2 , Figure 2 This is a flowchart illustrating a regional security protection method according to an exemplary embodiment. Figure 2 As shown, the security protection method for this area includes the following steps S101 to S102.

[0054] S101 receives configuration information for the detection opening conditions through the control device, and outputs an opening control signal to the intrusion detection device when the detection opening conditions are met.

[0055] The activation control signal is used to control the intrusion detection device to activate detection.

[0056] In some embodiments, the configuration information for the detection activation condition is the detection activation time information. The aforementioned satisfaction of the detection activation condition means that the current time reaches the corresponding detection activation time. That is, in step S101, when the current time reaches the corresponding detection activation time, the control device outputs an activation control signal to the intrusion detection device.

[0057] In some embodiments, the configuration information for detecting the opening condition is the detection opening instruction information. The aforementioned satisfaction of the detection opening condition means receiving the corresponding detection opening instruction information. That is, in step S101, when the control device receives the corresponding detection opening instruction information, it outputs an opening control signal to the intrusion detection device.

[0058] In some embodiments, the configuration information for the detection activation condition includes detection activation time information and detection activation command information. The aforementioned satisfaction of the detection activation condition means that the current time reaches the corresponding detection activation time and the corresponding detection activation command is received. That is, in step S101, when the current time reaches the corresponding detection activation time and the corresponding detection activation command is received, the control device outputs an activation control signal to the intrusion detection device.

[0059] The activation command can be manually input into the control device. Alternatively, it can be automatically generated based on pre-configuration and input into the control device.

[0060] S102, the intrusion detection device forms a detection medium at a preset position to define the area boundary, and outputs an alarm signal when an object is detected at the area boundary.

[0061] The objects include people, animals, and other items of any kind.

[0062] Specifically, the alarm signal can be an audible signal and / or a visual signal to alert staff at duty stations located near the operating site; at the same time, it alerts intruders at the boundary of the area.

[0063] Alarm signals can also be sent to the mobile phones, computers, and other electronic devices of staff at the duty station in the form of text messages to remotely notify the relevant staff.

[0064] It should be noted that the intrusion detection device only forms a detection medium at a preset position to define the area boundary upon receiving an opening control signal from the control device. That is, the detection medium formed by the intrusion detection device, instead of a physical door, divides the space into a first area and a second area. One of these two areas is designated as a protected area, and the other as an unprotected area, where personnel are permitted to remain. If an object is present at the boundary of the area defined by the detection medium, it is considered that personnel or other objects have entered or exited the protected area, thus triggering the intrusion detection device to output an alarm signal, thereby alerting staff at the duty station and other locations.

[0065] In some embodiments, in step S102, an intrusion detection device forms a detection light curtain at a preset position to define the area boundary. That is, the space is divided into a first area and a second area by using a detection light curtain instead of a physical door. Of course, in other embodiments, the detection light curtain can be replaced by other detection media, such as sound waves or water curtains.

[0066] It should be noted that during normal operation of the premises or in other situations where area security is not required, a shutdown control signal can be output from the control device to the intrusion detection device to control its shutdown. This prevents the intrusion detection device from interfering with normal operation of the premises and ensures that personnel and other objects can enter and exit the premises normally. Specifically, the control device can be configured with detection shutdown conditions, such as a shutdown time, so that when the shutdown time is reached, the control device outputs a shutdown control signal to the intrusion detection device to control its shutdown. Alternatively, during normal operation of the premises or in other situations where area security is not required, the intrusion detection device can also be manually shut down by staff.

[0067] This application uses a control device to output an activation control signal to activate an intrusion detection device when the activation conditions are met. At this time, the intrusion detection device forms a detection medium at a preset location, thereby defining the area boundary. The device detects whether an object is present at the area boundary and outputs an alarm signal upon detection, enabling monitoring of personnel entering and exiting the protected area in the operational location. The location of the intrusion detection device can be flexibly set, and the shape and size of the detection medium can be changed according to needs. The activation time of the intrusion detection device can also be flexibly configured, providing high security flexibility while solving the problem of high maintenance and installation costs associated with physical doors. Furthermore, the location forming the detection medium can be fully utilized for projecting dynamic images, static images, advertising videos, promotional films, etc., for product advertising.

[0068] It should be noted that this application can be applied to replace physical doors when an operating venue closes for monitoring whether people or other objects are entering or leaving a protected area. For example, this can be used in shopping malls, supermarkets, libraries, stadiums, subway stations, and other operating venues to monitor whether people or other objects are entering or leaving a protected area when the venue closes for business. This application can also be applied to replace physical doors during normal operating hours of an operating venue for monitoring whether people or other objects are entering or leaving a protected area. For example, this can be used in factories, schools, and other operating venues to check whether people or other objects are entering or leaving a protected area during normal operating hours.

[0069] Figure 3 This is a flowchart illustrating a regional security protection method according to another exemplary embodiment. This regional security protection method is applicable to situations where the regional security protection system includes an audio playback device, such as… Figure 3 As shown, the security protection method for this area includes the following steps S201 to S207.

[0070] S201, receives configuration information for detecting opening conditions through the control device.

[0071] S202, the control device determines whether it has received the corresponding detection start command information. If so, proceed to step S203.

[0072] S203, send an audio playback control signal to the audio playback device.

[0073] It should be noted that the audio playback control signal can be generated by the control device and sent to the audio playback device, or it can be generated by other devices and sent to the audio playback device.

[0074] S204, play a prompt audio through an audio playback device.

[0075] The audio prompts indicate that the intrusion detection device is about to activate, thus reminding people near the area boundary to leave and reminding staff to move items at the area boundary.

[0076] S205, the control device counts down for the first duration, and when the countdown ends, proceed to step S206.

[0077] The first duration can be flexibly set according to needs, such as 10 seconds, 20 seconds, or one minute. In some embodiments, the first duration is set as the time difference between the current time and the detection start time configured in step S201.

[0078] By setting a countdown timer, a buffer period is provided to allow staff to handle objects at the area boundaries and disperse lingering personnel. Of course, in some embodiments, the countdown timer may not be set, and the next step S206 can proceed immediately after sending the audio playback control signal to the audio playback device.

[0079] S206, the control device outputs an open control signal to the intrusion detection device.

[0080] The activation control signal is used to control the intrusion detection device to activate detection.

[0081] In some embodiments, when the countdown ends, an audio shutdown control signal is simultaneously sent to the audio playback device, causing the audio playback device to stop playing the prompt audio. In some embodiments, the audio playback device may also be configured to play the prompt audio based on a continuous audio playback control signal, wherein during the first countdown duration, an audio playback control signal is continuously sent to the audio playback device for a set first duration, causing the audio playback device to play the prompt audio for the first duration.

[0082] S207 uses an intrusion detection device to form a detection medium at a preset location to define the boundary of an area, and outputs an alarm signal when an object is detected at the boundary of the area.

[0083] Figure 4 This is a flowchart illustrating a regional security protection method according to yet another exemplary embodiment. This regional security protection method is applicable to situations where the regional security protection system includes an audio playback device, a camera device, and a video management device, such as… Figure 4 As shown, the security protection method for this area includes the following steps S301 to S309.

[0084] S301, the control device sends a video request message containing the identification information of the camera device to the video management device.

[0085] The video management device is connected to the control device, and the video management device stores the surrounding environment video of the area boundary collected by each camera device.

[0086] S302, the video management device retrieves the video stream corresponding to the identification information and generates a video playback address, which is then sent to the control device.

[0087] S303, the control device receives the video playback address and plays the video, and accepts the detection start command input operation after playing the video.

[0088] The detection activation command includes the identification information of the camera device. The control device stores the mapping relationship between camera devices and intrusion detection devices, and queries the corresponding intrusion detection device based on the identification information in the detection activation command.

[0089] In detail, the identification information may be, for example, the ID information of the camera device.

[0090] S304, the control device sends a detection start command to the video management device.

[0091] S305, the video management device sends an audio playback control signal to the audio playback device based on the identification information in the detection start command.

[0092] It should be noted that, in Figure 4 In the illustrated embodiment, the video management device stores a mapping relationship between the camera device and the audio playback device. The video management device sends audio playback control signals to the corresponding audio playback device. Of course, in other embodiments, the audio playback control signals can also be sent to the corresponding audio playback devices through other devices. For example, the control device stores a mapping relationship between the camera device and the audio playback device, and the control device directly sends audio playback control signals to the corresponding audio playback devices.

[0093] S306, play a prompt audio through an audio playback device.

[0094] S307, the control device counts down for the first duration, and when the countdown ends, proceed to step S308.

[0095] S308, the control device outputs an opening control signal to the intrusion detection device corresponding to the identification information based on the detection opening command.

[0096] The activation control signal is used to control the intrusion detection device corresponding to the identification information to activate detection.

[0097] S309 uses an intrusion detection device to form a detection medium at a preset location to define the boundary of an area, and outputs an alarm signal when an object is detected at the boundary of the area.

[0098] exist Figure 4 In the illustrated embodiment, before the control device outputs an activation control signal to the intrusion detection device, it first acquires video footage of the surrounding environment at the area boundary to understand the surrounding environment, such as whether there are people lingering or objects placed around the area boundary. This allows staff to take appropriate action, such as moving objects placed at the area boundary or reminding people lingering at the area boundary to leave, ensuring the normal detection function of the subsequent intrusion detection device. The video request information includes the identification information of the camera device. In the case of multiple camera devices, this ensures that the video management device can send the addresses of the surrounding environment videos collected by the corresponding camera devices to the control device.

[0099] It should be noted that in some embodiments, before step S301, the method may include receiving detection start time information through a control device. Accordingly, in step S307, the control device may be configured to start a countdown when the current time is a first duration away from the received detection start time.

[0100] In some embodiments, further, in step S309, the intrusion detection device outputs an alarm signal to the audio playback device, the control device, and the video management device when it detects an object at the area boundary. The audio playback device alerts staff at the duty station near the operating location and simultaneously warns any intruders at the area boundary. The control device displays the alarm signal and / or plays an alarm prompt audio to remotely notify the relevant staff. The video management device plays back the video based on the alarm signal and captures an image of the surrounding environment at the corresponding time of the area boundary, then sends the image to the control device so that staff can understand the cause of the alarm.

[0101] Please refer to the following. Figure 1 ,like Figure 1 As shown, the area security protection system 100 includes an intrusion detection device 101 and a control device 102.

[0102] The intrusion detection device 101 is used to form a detection medium at a preset location to define the boundary of an area. The intrusion detection device 101 can detect whether an object is at the boundary of the area and output an alarm signal when an object is detected at the boundary of the area.

[0103] In some embodiments, the intrusion detection device 101 includes a light curtain assembly for forming a detection light curtain, which serves as a detection medium to define the boundary of an area. For example, the intrusion detection device 101 is an infrared photoelectric protection device capable of forming a detection light curtain.

[0104] In some embodiments, the intrusion detection device 101 may be a device that forms other forms of detection media, such as a security scanning radar capable of forming sound waves.

[0105] The control device 102 is communicatively connected to the intrusion detection device 101, and is used to receive configuration information for the detection activation conditions, and output an activation control signal when the detection activation conditions are met. The activation control signal is used to control the intrusion detection device 101 to activate the detection.

[0106] It should be noted that the control device can be configured to output a shutdown control signal to the intrusion detection device during normal operation of the premises or in other situations where area security protection is not required, thereby controlling the intrusion detection device to shut down. This avoids the intrusion detection device's installation affecting the normal operation of the premises and ensures that personnel and other objects can enter and exit the premises normally. Specifically, the control device can be configured with detection shutdown condition information, such as a detection shutdown time. When the detection shutdown time is reached, the control device outputs a shutdown control signal to the intrusion detection device to control it to shut down.

[0107] In some embodiments, the detection start condition is the detection start time, and the control device 102 is used to output an start control signal when the current time reaches the detection start time.

[0108] In some embodiments, the detection activation condition is receiving a corresponding detection activation command, and the control device 102 is used to output an activation control signal when the corresponding detection activation command is received.

[0109] In some embodiments, the detection start conditions include detection start time and detection start command. The control device 102 is used to output an start control signal when the current time reaches the detection start time and the corresponding detection start command is received.

[0110] Furthermore, in some embodiments, the control device 102 is also configured to send video request information to the video management device to obtain the playback address of the surrounding environment video of the area boundary, and to play the surrounding environment video of the area boundary based on the playback address, and to accept the detection start command input operation after playing the video.

[0111] Please refer to the following. Figure 5 , Figure 5 This is a schematic diagram illustrating a regional security protection system according to an exemplary embodiment. Figure 5 As shown, the area security protection system 100 further includes several camera devices 103 and video management devices 104.

[0112] Among them, several camera devices 103 are set around the perimeter of the area boundary to collect video of the surrounding environment of the area boundary.

[0113] Specifically, camera devices 103 are installed on both the inner and outer sides of the area boundary to better capture video of the surrounding environment. The inner side of the area boundary refers to the protected area, while the outer side refers to the unprotected area.

[0114] In some embodiments, the camera device 103 integrates an audio playback device, which is communicatively connected to the intrusion detection device and is used to issue an alarm based on the alarm signal output by the intrusion detection device, so as to remind the staff at the duty point located near the operating site, and at the same time, to warn the intruders at the boundary of the area.

[0115] Furthermore, in some embodiments, the audio playback device can play a prompt audio based on an audio playback control signal to indicate that the intrusion detection device is about to start detection, thereby reminding personnel located around the area boundary to leave and reminding staff to move items located at the area boundary.

[0116] It should be noted that the audio playback device can be communicatively connected to the control device 102 to receive audio playback control signals. Alternatively, the audio playback device can be communicatively connected to other devices, which can output audio playback control signals to the audio playback device based on the output signals of the control device 102, causing the audio playback device to play prompt audio.

[0117] It should be noted that in some embodiments, the audio playback device may be set independently of the camera device 103, and is not limited to being integrated with the camera device 103.

[0118] The video management device 104 is communicatively connected to each camera device 103 and the control device 102. The video management device 104 is used to receive and store the surrounding environment video collected by the camera devices 103. Furthermore, the video management device 104 can send the video playback address corresponding to the surrounding environment video collected by the camera device 103 to the control device 102 based on the video request information from the control device 102.

[0119] In some embodiments, the video management device 104 is a network video recorder (NVR).

[0120] In some embodiments, the video management device 104 is also communicatively connected to the intrusion detection device 101. Based on the alarm signal output by the intrusion detection device 101, the video management device 104 plays back the corresponding video and captures the surrounding environment image of the area boundary at the corresponding time, and sends the surrounding environment image to the control device 102 so that the staff can know the reason for the alarm.

[0121] In some embodiments, the area security protection system 100 includes a plurality of intrusion detection devices 101. The control device 102 stores the mapping relationship between the camera device 103 and the intrusion detection device 101, and outputs an activation control signal to the corresponding intrusion detection device based on the detection activation command.

[0122] In some embodiments, the regional security protection system 100 includes multiple intrusion detection devices 101, multiple control devices 102, multiple camera devices 103, video management devices 104, a control server 105, and a communication network architecture, which can be used to provide security protection for multiple operating locations.

[0123] Each intrusion detection device 101 is installed in its respective operating location to replace a physical door. An operating location may have one intrusion detection device 101 or multiple intrusion detection devices 101.

[0124] Multiple control devices 102 are respectively set up at the duty point. Each control device 102 is connected to the control server 105 to independently complete data processing and control each intrusion detection device 101.

[0125] Multiple camera devices 103 are respectively installed in the corresponding operating locations to collect video of the surrounding environment at the boundaries of each area. At least some of the camera devices 103 have integrated audio playback devices and can issue alarms based on the alarm signals output by the intrusion detection device 101 and play prompt audio based on the received audio playback control signals.

[0126] The video management device 104 is communicatively connected to multiple camera devices 103 to receive and store the surrounding environment videos captured by each camera device 103. Furthermore, the video management device 104 stores identification information for each camera device 103. When it receives a video request message from the control device 102, the video management device 104 retrieves the video stream based on the identification information in the video request message and generates a video playback address, which is then sent to the control device 104. This enables the control device 104 to play the surrounding environment video of the area boundary captured by the camera device 103 corresponding to the identification information.

[0127] For example, the video request information sent by the control device 102 contains the ID information of 10 camera devices 103. The video management device 104 then generates video playback addresses corresponding to the 10 camera devices 103 and sends them to the control device 104. Subsequently, the detection start command sent by the control device contains the ID information of 8 camera devices 103. At this time, the video management device 104 outputs audio playback control signals to the 8 camera devices 103, causing the audio playback devices integrated into the corresponding 8 camera devices 103 to play prompt audio.

[0128] The communication network architecture includes an IoT server 106, a core switch 107, an aggregation switch 108, multiple access switches 109, and an edge gateway 110.

[0129] exist Figure 5In the illustrated embodiment, the IoT server 106, core switch 107, access switch 109, control server 105, and some control devices 102 are located on the central side, while other access switches 109, edge gateways 110, video management devices 104, camera devices 103, some control devices 102, and intrusion detection devices 101 are located on the local side, corresponding to the operational location. By setting up a central location, the overall architecture of the security protection system is simplified while still enabling security protection for multiple operational locations, thereby saving equipment costs.

[0130] The core switch 107 is communicatively connected to the control server 105, the IoT server 106, the aggregation switch 108, and the access switches 109 on the central side. The aggregation switch 108 is communicatively connected to each access switch 109 on the local side. On the local side, one access switch 109 is communicatively connected to the camera device 103 and the intrusion detection device 101 via the edge gateway 110, another access switch 109 is communicatively connected to the video management device 104, and multiple access switches 109 are each communicatively connected to a control device 102. On the central side, the access switches 109 are communicatively connected to each control device 102. This enables communication connections between the various devices.

[0131] It should be noted that in some embodiments, a central side may not be set up. Instead, a complete regional security protection system may be set up in each operating location. That is, the regional security protection system is suitable for providing security protection for an operating location.

[0133] It should be understood that this application is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
