[0042] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] The security communication system provided in the embodiment of the present application can be applied to the security warehouse as shown in Figure 1. The security warehouse is composed of a wall panel 101 and a door 102. The security warehouse can be a cubic structure. The wall panel 101 of the security warehouse can include a top wall panel, a bottom wall panel, and four side wall panels. The door 102 can be located on any side wall panel. A security communication system is deployed in the safe warehouse, which includes an electromagnetic field detection host 103 built into the wall panel 101 of the safe warehouse, a door lock sensor 104, a main controller 105, and a voice alarm 106 built into the safe warehouse; wherein the electromagnetic field detection host 103 is used to obtain metal information and send the metal information to the main controller 105; the door lock sensor 104 is used to detect the door status of the safe warehouse and send the door status to the main controller 105; the main controller 105 is used to obtain metal information and door status; when the metal information and door status meet the security communication conditions, the conference system is started; when the metal information and door status do not meet the security communication conditions, an alarm signal is generated and sent to the voice alarm 106; the voice alarm 106 is used to make a voice alarm when the alarm signal is received.

[0044] Among them, the safety warehouse refers to a facility for isolating sensitive information. A conference system is deployed in the safety warehouse, which can be used for participants to hold meetings in the safety warehouse. In some embodiments, the conference system can be a naked-eye 3D video conference system or other forms of conference systems. Taking the naked-eye 3D video conference system as an example, the conference system includes a 3D display screen 107. Other forms of conference systems may include ordinary video forms, voice forms, etc., and the conference equipment included in the conference system can be flexibly selected according to actual conditions.

[0045] The electromagnetic field detection host determines whether there is a metal object by measuring and detecting the electromagnetic radiation obtained. When the metal object is placed in the sensing area of ​​the electromagnetic field detection host, the metal information such as the existence and location of the metal object is determined by the echo of the electromagnetic signal. For example, the electromagnetic field detection host can be located in the rear wall panel built into the safety warehouse.

[0046] The warehouse door is opened and closed by the door lock, and the door lock sensor is used to detect the open and closed state of the door lock of the warehouse door. When the door lock is opened or closed, the door lock sensor will use the door lock state as the warehouse door state and send it to the main controller in the form of an electrical signal. For example, the door lock sensor can be built into the front wall panel of the security warehouse.

[0047] FIG2 is a block diagram of a security communication system in an embodiment. The main controller is responsible for the scheduling of the entire security communication system. It receives the metal information sent by the electromagnetic field detection host and the door status sent by the door lock sensor to determine whether the security communication conditions are met. If the security communication conditions are met, the conference system is started. If the security communication conditions are not met, the conference system is not allowed to start, and an alarm signal is generated, and a voice alarm is performed through a voice alarm. Exemplarily, the main controller can be built into the back wall of the security warehouse.

[0048] The above-mentioned security communication system is applied to the security warehouse. The system includes an electromagnetic field detection host built into the wall panel of the security warehouse, a door lock sensor, a main controller, and a voice alarm built into the security warehouse. The electromagnetic field detection host can detect metal information, and the door lock sensor can detect the door status of the security warehouse. By judging whether the metal information and the door status meet the security communication conditions, it can issue a voice alarm when metal equipment is brought into the security warehouse, and ensure that the conference system is started when no metal equipment is brought into the security warehouse, thereby avoiding information leakage of the conference system, which is conducive to improving the security of meetings in the security warehouse.

[0049] In an exemplary embodiment, the security communication system further includes: an electromagnetic field detection coil, including a transmitting coil and an induction coil; the transmitting coil and the induction coil are both connected to the electromagnetic field detection host.

[0050] The electromagnetic field detection host detects metal information through an electromagnetic field detection coil, and the electromagnetic field detection coil is connected to the electromagnetic field detection host. In some embodiments, the electromagnetic field detection coil includes a transmitting coil and an induction coil, both of which are connected to the electromagnetic field detection host.

[0051] Among them, the transmitting coil is used to transmit electromagnetic signals, and the induction coil is used to receive echo signals. The transmitting coil generates a high-frequency magnetic field through current excitation. This magnetic field will pass through the object being detected and induce eddy currents inside the metal object. Eddy currents in turn generate magnetic fields, which will be induced through the receiving coil. The receiving coil converts the induced signal into an electrical signal, which is then processed and output. Since different metals have different electrical conductivity and magnetic permeability, different metal objects respond differently to electromagnetic fields. The electromagnetic field detection host determines the metal information based on the signal in the receiving coil. The metal information includes the metal type and location.

[0052] In this embodiment, the system also includes an electromagnetic field detection coil connected to the electromagnetic field detection host. The electromagnetic signal is emitted by the transmitting coil, and the induction coil receives the echo signal to obtain metal information, which is beneficial for detecting metal objects entering the security warehouse, thereby preventing the risk of conference information leakage caused by metal equipment such as recording devices being brought into the security warehouse.

[0053] In an exemplary embodiment, the electromagnetic field detection coil includes a top transmitting coil and a top induction coil built into the top wall panel of the safety warehouse, and a bottom transmitting coil and a bottom induction coil built into the bottom wall panel of the safety warehouse.

[0054] Among them, the electromagnetic field detection coil can be deployed in the top wall panel and the bottom wall panel of the safety warehouse. For example, a group of transmitting coils and receiving coils are deployed in the top wall panel, and another group of transmitting coils and receiving coils are deployed in the bottom wall panel. As shown in Figure 3, a schematic diagram of the distribution of electromagnetic field detection coils in one embodiment. As shown in Figure 4, a top view of the distribution of the warehouse bottom detection coils in one embodiment. Among them, the warehouse bottom transmitting coil 108 and the warehouse bottom induction coil 109 are built into the bottom wall panel of the safety warehouse, and the warehouse top transmitting coil 110 and the warehouse top induction coil 111 are built into the top wall panel of the safety warehouse.

[0055] In this embodiment, by deploying electromagnetic field detection coils in the top wall panel and the bottom wall panel of the safety warehouse, the detection signals from the top and the bottom can complement and verify each other, thereby improving the overall detection effect. Even small and hidden metal objects can be effectively detected; the metal information of the safety warehouse can be detected from multiple angles, reducing detection blind spots and improving detection accuracy and reliability.

[0056] In an exemplary embodiment, the electromagnetic field detection coil includes a first door side transmitting coil and a first door side induction coil built into the wall panel on one side of the door of the safety warehouse, and a second door side transmitting coil and a second door side induction coil built into the wall panel on the other side of the door of the safety warehouse.

[0057] Among them, since the warehouse door is located on the side wall panel of the safety warehouse, the wall panel on one side of the warehouse door and the wall panel on the other side of the warehouse door are the wall panels on the left and right sides of the warehouse door.

[0058] The embodiment of the present application proposes that electromagnetic field detection coils can be deployed in the side wall panels on both sides of the warehouse door. FIG5 is a schematic diagram of the distribution of electromagnetic field detection coils in another embodiment. FIG6 is a front view of the distribution of warehouse side detection coils in one embodiment. Among them, the first door side transmitting coil 112 and the first door side induction coil 113 are built into the top wall panel of the wall panel on one side of the warehouse door, and the second door side transmitting coil 114 and the second door side induction coil 115 are built into the wall panel on the other side of the warehouse door.

[0059] In other embodiments, electromagnetic field detection coils may be deployed inside the top wall panels, bottom wall panels, and wall panels on both sides of the safety warehouse door to improve the accuracy and reliability of detection.

[0060] In this embodiment, by deploying the electromagnetic field detection coils in the wall panels on both sides of the door of the safety warehouse, the detection signals on both sides can complement and verify each other, thereby improving the overall detection effect. Even small and hidden metal objects can be effectively detected; the metal information of the safety warehouse can be detected from multiple angles, reducing detection blind spots and improving detection accuracy and reliability.

[0061] In an exemplary embodiment, the main controller is also used to generate a door not closed alarm signal and send it to the voice alarm when the door status indicates that the door is not closed, so as to instruct the voice alarm to make a voice alarm based on the door not closed alarm signal; when the door status indicates that the door is closed and the metal information indicates the presence of metal equipment, generate a metal equipment alarm signal and send it to the voice alarm, so as to instruct the voice alarm to make a voice alarm based on the metal equipment alarm signal.

[0062] In order to ensure the safety of the meeting, the door should be in a closed state before starting the conference system. When the door status indicates that the door is not closed, the main controller should generate a door not closed alarm signal to instruct the voice alarm to issue a voice alarm based on the door not closed alarm signal.

[0063] The metal detection function is activated after the door is closed. When the door status indicates that the door is closed, it is determined whether there is a metal device based on the metal information; if the metal information indicates that there is a metal device, a metal device alarm signal is generated to instruct the voice alarm to make a voice alarm based on the metal device alarm signal. In some embodiments, the metal device alarm signal is also used to prompt the user to place the metal device outside the safe warehouse.

[0064] Figure 7 is a schematic diagram of the metal detection process in an embodiment. The electromagnetic field detection host generates an electromagnetic field by exciting the transmitting coil through a changing current. After sensing the metal device, the electromagnetic field changes, and the signal induced by the induction coil is converted into a current signal, which is processed and output to the electromagnetic field detection host; the electromagnetic field detection host generates a metal device alarm signal and sends it to the voice alarm.

[0065] As shown in FIG8 , this is a flowchart of the workflow of a secure communication system in an embodiment. Among them, the user opens the door to enter the secure warehouse and turns on the conference equipment. When the conference system enters the startup procedure, the secure warehouse performs a safety check before starting the conference system. First, the signal of the door lock sensor is read to determine the state of the door to confirm whether the door is closed. If the door is not closed, the voice alarm triggers a voice alarm and prompts the user to close the door. The voice alarm stops the alarm only after the user closes the door. After confirming that the door is closed, the metal information detection link is entered. If a metal device is detected in the secure warehouse, the voice alarm triggers an alarm and prompts the user to put the metal outside the secure warehouse. When the user opens the door and puts the metal device outside the warehouse, the system will detect whether the door is closed again to ensure that the door is in a closed state.

[0066] In this embodiment, when the door status indicates that the door is not closed, a voice alarm is issued to remind the user to close the door before holding the meeting, which is beneficial to improving the security of the meeting; when the door status indicates that the door is closed and the metal information indicates the presence of metal equipment, a voice alarm is issued to remind the user that there is metal equipment entering the safety warehouse, which is beneficial to further improving the security of the meeting.

[0067] In an exemplary embodiment, the main controller is also used to start the conference system when the door status indicates that the door is closed and the metal information indicates that there is no metal equipment. At this time, the user can conduct a confidential video conference.

[0068] Among them, when the warehouse door is closed and there is no metal equipment, it means that the conditions for safe communication are met and the conference system can be started.

[0069] In this embodiment, the conference system is started when the door status indicates that the door is closed and the metal information indicates that there is no metal equipment. The door status and metal information both meet the security communication conditions, effectively avoiding the security risk of leaking conference information through metal equipment such as recording devices, which is conducive to improving the security of the meeting.

[0070] In an exemplary embodiment, the main controller is also used to generate a reminder to shut down the conference equipment when the meeting end information is detected; when the meeting end information is detected and the conference equipment has not been operated for more than a preset time, the conference equipment is shut down.

[0071] After the meeting, the main controller generates a reminder to shut down the conference equipment to remind the user to shut down the conference equipment in time. If the user does not shut down the equipment in time, the duration of inactivity of the conference equipment is detected. If the duration exceeds a preset duration, for example, 10 minutes, the conference equipment is shut down to avoid leakage of conference information.

[0072] In some embodiments, referring to FIG8 , after the meeting is over, the user leaves the safe warehouse, and the main controller needs to control the safe warehouse to close. If the door is not closed after the user leaves the safe warehouse, a reminder to close the door is generated to remind the user to close the door. After the door is closed, the reminder to close the door ends, and the use of the safe warehouse for the meeting ends.

[0073] In this embodiment, after the meeting, a reminder to shut down the conference equipment is generated. If the conference equipment has no operation for more than a preset time, the conference equipment is shut down, which is helpful to avoid leakage of conference information and improve conference security.

[0074] In an exemplary embodiment, as shown in FIG9 , a secure communication method is provided, which is described by taking the method applied to the master controller 105 in the secure communication system in FIG1 as an example, and includes the following steps 902 to 906. Among them:

[0075] Step 902, obtaining metal information and door status.

[0076] Step 904: When the metal information and the door status meet the safety communication conditions, start the conference system.

[0077] Step 906, when the metal information and the door status do not meet the safety communication conditions, an alarm signal is generated and sent to the voice alarm to instruct the voice alarm to make a voice alarm when receiving the alarm signal.

[0078] Among them, metal information is obtained by receiving the signal sent by the electromagnetic field detection host, and the door status is obtained by receiving the signal sent by the door lock sensor. Metal information is used to indicate whether a metal device is detected. The door status is used to indicate whether the door is closed.

[0079] The main controller is responsible for the scheduling of the entire security communication system. It determines whether the security communication conditions are met by receiving the metal information sent by the electromagnetic field detection host and the warehouse door status sent by the door lock sensor. If the security communication conditions are met, the conference system is started. If the security communication conditions are not met, the conference system is not allowed to be started, and an alarm signal is generated, and a voice alarm is issued through the voice alarm.

[0080] The above-mentioned security communication method is applied to the security communication system in the security warehouse. The system includes an electromagnetic field detection host built into the wall panel of the security warehouse, a door lock sensor, a main controller, and a voice alarm built into the security warehouse. The electromagnetic field detection host can detect metal information, and the door lock sensor can detect the door status of the security warehouse. By judging whether the metal information and the door status meet the security communication conditions, a voice alarm can be issued when metal equipment is brought into the security warehouse, and the conference system can be started when no metal equipment is brought into the security warehouse, thereby avoiding information leakage of the conference system and improving the security of meetings in the security warehouse.

[0081] In an exemplary embodiment, when the metal information and the warehouse door status do not meet the safety communication conditions, an alarm signal is generated and sent to the voice alarm to instruct the voice alarm to make a voice alarm when receiving the alarm signal, including: when the warehouse door status indicates that the warehouse door is not closed, a warehouse door not closed alarm signal is generated and sent to the voice alarm to instruct the voice alarm to make a voice alarm based on the warehouse door not closed alarm signal; when the warehouse door status indicates that the warehouse door is closed and the metal information indicates the presence of metal equipment, a metal equipment alarm signal is generated and sent to the voice alarm to instruct the voice alarm to make a voice alarm based on the metal equipment alarm signal.

[0082] In order to ensure the safety of the meeting, the door should be in a closed state before starting the conference system. When the door status indicates that the door is not closed, the main controller should generate a door not closed alarm signal to instruct the voice alarm to issue a voice alarm based on the door not closed alarm signal.

[0083] The metal detection function is activated after the door is closed. When the door status indicates that the door is closed, it is determined whether there is a metal device based on the metal information; if the metal information indicates that there is a metal device, a metal device alarm signal is generated to instruct the voice alarm to make a voice alarm based on the metal device alarm signal. In some embodiments, the metal device alarm signal is also used to prompt the user to place the metal device outside the safe warehouse.

[0084] Referring to Figure 7, the electromagnetic field detection host generates an electromagnetic field by exciting the transmitting coil through changing current. After sensing the metal equipment, the electromagnetic field changes, and the signal induced by the induction coil is converted into a current signal, which is output to the electromagnetic field detection host after processing; the electromagnetic field detection host generates a metal equipment alarm signal and sends it to the voice alarm.

[0085] Referring to Figure 8, the user opens the door to enter the security warehouse and turns on the conference equipment. When the conference system enters the startup procedure, the security warehouse performs a safety check before starting the conference system. First, it reads the signal of the door lock sensor to determine the state of the door to confirm whether the door is closed. If the door is not closed, the voice alarm triggers a voice alarm and prompts the user to close the door. The voice alarm stops alarming only after the user closes the door. After confirming that the door is closed, the metal information detection link is entered. If metal equipment is detected in the security warehouse, the voice alarm triggers an alarm and prompts the user to put the metal outside the security warehouse. When the user opens the door and puts the metal equipment outside the warehouse, the system will detect whether the door is closed again to ensure that the door is in a closed state.

[0086] In this embodiment, when the door status indicates that the door is not closed, a voice alarm is issued to remind the user to close the door before holding the meeting, which is beneficial to improving the security of the meeting; when the door status indicates that the door is closed and the metal information indicates the presence of metal equipment, a voice alarm is issued to remind the user that there is metal equipment entering the safety warehouse, which is beneficial to further improving the security of the meeting.

[0087] In an exemplary embodiment, when the metal information and the door status meet the safety communication conditions, starting the conference system includes: when the door status indicates that the door is closed and the metal information indicates that there is no metal equipment, starting the conference system.

[0088] Among them, when the warehouse door is closed and there is no metal equipment, it means that the conditions for safe communication are met and the conference system can be started.

[0089] In this embodiment, the conference system is started when the door status indicates that the door is closed and the metal information indicates that there is no metal equipment. The door status and metal information both meet the security communication conditions, effectively avoiding the security risk of leaking conference information through metal equipment such as recording devices, which is conducive to improving the security of the meeting.

[0090] In an exemplary embodiment, the secure communication method further includes: generating a conference device shutdown reminder when conference end information is detected; shutting down the conference device when conference end information is detected and the conference device has no operation for more than a preset time.

[0091] After the meeting, the main controller generates a reminder to shut down the conference equipment to remind the user to shut down the conference equipment in time. If the user does not shut down the equipment in time, the duration of inactivity of the conference equipment is detected. If the duration exceeds a preset duration, for example, 10 minutes, the conference equipment is shut down to avoid leakage of conference information.

[0092] In some embodiments, referring to FIG8 , after the meeting is over, the user leaves the safe warehouse, and the main controller needs to control the safe warehouse to close. If the door is not closed after the user leaves the safe warehouse, a reminder to close the door is generated to remind the user to close the door. After the door is closed, the reminder to close the door ends, and the use of the safe warehouse for the meeting ends.

[0093] In this embodiment, after the meeting, a reminder to shut down the conference equipment is generated. If the conference equipment has no operation for more than a preset time, the conference equipment is shut down, which is helpful to avoid leakage of conference information and improve conference security.

[0094] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0095] Based on the same inventive concept, the embodiment of the present application also provides a secure communication device for implementing the secure communication method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in the one or more secure communication device embodiments provided below can refer to the limitations on the secure communication method above, and will not be repeated here.

[0096] In an exemplary embodiment, as shown in FIG. 10 , a safety communication device 100 is provided, which is applied to the above-mentioned safety communication system, and includes: an acquisition module 120, a start module 140 and an alarm module 160, wherein:

[0097] The acquisition module 120 is used to acquire metal information and warehouse door status.

[0098] The starting module 140 is used to start the conference system when the metal information and the door status meet the safety communication conditions.

[0099] The alarm module 160 is used to generate an alarm signal when the metal information and the door status do not meet the safety communication conditions, and send it to the voice alarm to instruct the voice alarm to make a voice alarm when receiving the alarm signal.

[0100] The above-mentioned security communication device and security communication system are applied to the security warehouse. The system includes an electromagnetic field detection host, a door lock sensor, a main controller, and a voice alarm built into the wall panel of the security warehouse.
