Description

Technical Field

[0001] This invention relates to the field of security monitoring technology, specifically to a computer network information security monitoring device and method. Background Technology

[0002] As the core storage location for servers, the data center provides a good environment for servers through systems such as precision air conditioning, UPS uninterruptible power supply, and lightning protection grounding. It can not only alarm or handle emergency situations during server operation, but also restrict unauthorized personnel from entering through access control systems, biometric identification, surveillance cameras, and anti-tailgating devices, prevent hardware theft or damage, and reduce the risk of data leakage. It is a key facility to ensure data security, business continuity, and compliance.

[0003] In existing data center monitoring systems, camera surveillance offers real-time and continuous monitoring, recording personnel operations for easy tracing and equipment status inspections, replacing some manual checks, reducing security loopholes caused by human error, and ensuring information security. However, individual cameras have blind spots below or behind, preventing continued environmental data collection when physically damaged or obstructed by an attacker. Furthermore, data center monitoring systems typically rely on administrator privileges; if an attacker gains access, they can tamper with displayed camera data and shut down operating cameras, leading to information security breaches. Therefore, this invention provides a computer network information security monitoring device to reduce blind spots during monitoring while maintaining image data collection even when cameras are off or damaged externally. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a computer network information security monitoring device and method, which reduces blind spots during monitoring and maintains the acquisition of external image data even when the camera is turned off or damaged.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A computer network information security monitoring device includes several camera bodies arranged in a computer room. Each camera body includes a housing, an imaging mechanism for acquiring external images, and a lens group for adjusting the focus. Adjacent camera bodies are fixedly connected by a linkage mechanism, which is used to make the movement directions of adjacent cameras rotate alternately.

[0006] A connection mechanism is provided between the imaging mechanism and the lens assembly. The connection mechanism includes a central shaft, a first contact and a second contact. The first contact and the second contact are arranged vertically. The first contact is connected to an external circuit, and the second contact is electrically connected to a backup power supply located inside the housing.

[0007] The lens assembly is fixedly connected to a circuit connection channel for switching the imaging mechanism to connect to the first contact or the second contact. The side of the lens assembly closest to the imaging mechanism is fixedly connected to the central axis. An electromagnet for attracting the imaging mechanism is fixedly connected to the central axis. The circuit connection channel is located on both sides of the central axis.

[0008] When the lens assembly is in its normal state, the circuit connection channel is connected to the first contact circuit, and the electromagnet is activated; when the lens assembly and the imaging mechanism are in an alternating state, the circuit connection channel is connected to the second contact circuit, and the electromagnet is deactivated.

[0009] Furthermore, the collaborative mechanisms include both fixed and mobile testing facilities;

[0010] The fixed testing mechanism includes several fixed plates, with connecting rollers rotating inside the fixed plates. A belt is clamped onto the connecting rollers, and a guide hole is opened on one side of the fixed plate. The belt is fitted with the guide hole with a clearance.

[0011] The mobile detection mechanism includes a lead screw, a power component is coaxially fixedly connected to one end of the lead screw, a nut block is slidably fitted on the lead screw, a connecting block is fixedly connected to one side of the nut block, a driving component is fixedly connected to the connecting block, a connecting shaft is fixedly connected to the output shaft of the driving component, the connecting shaft is rotatably fitted with the nut block, and one end of the connecting shaft is fixedly connected to the outer shell.

[0012] A locking block is slidably fitted at the end of the connecting shaft away from the connecting block. Several springs are connected between the locking block and the connecting shaft. The locking block is located between the connecting roller and the connecting shaft. A slot for placing the locking block is opened at the center of the connecting roller.

[0013] Furthermore, the fixed plates on the fixed testing mechanism are arranged in the four corners of the computer room.

[0014] Furthermore, a guide groove communicating with the card slot is opened on one side of the connecting roller, and the end of the card block away from the connecting shaft is arc-shaped. A magnet block for adsorbing the card block is fixedly connected in the card slot.

[0015] Furthermore, the imaging mechanism has a groove on the side closest to the lens group, with the first contact point located on the side of the groove away from the lens group and the second contact point located on both sides of the groove;

[0016] An extension block is fixedly connected to the side of the lens assembly near the imaging mechanism. The central shaft is fixedly connected to the extension block. Both the central shaft and the electromagnet are located in the slide groove, and the central shaft slides in conjunction with the slide groove. The circuit connection channel is located on the extension block.

[0017] When the lens assembly is in its normal state, the extension block blocks the slide groove, the circuit connection channel is connected to the first contact circuit, and the electromagnet is activated; when the lens assembly and the imaging mechanism are in an interleaved state, the extension block does not completely block the slide groove, the circuit connection channel is connected to the second contact circuit, and the electromagnet is deactivated.

[0018] Furthermore, ventilation channels are connected to both sides of the lens assembly. One end of the ventilation channel is located on the side of the extension block closer to the imaging mechanism, and the other end of the ventilation channel is located on the side of the lens assembly away from the imaging mechanism.

[0019] Furthermore, a photoresistor module for measuring the intensity of external light is also installed in the ventilation channel, and the photoresistor module is electrically connected to the imaging mechanism.

[0020] The imaging mechanism is also used to compare the light intensity with a set standard value. If the light intensity is less than the standard value, an abnormal display command is sent to the outside world; if the light intensity is greater than the standard value, a normal command is sent to the outside world.

[0021] Furthermore, a computer network information security monitoring method, based on the above-mentioned computer network information security monitoring device method, includes the following steps: Step 1: Manually arrange the fixed plates in the four corners of the computer room, use belts to connect the fixed plates in the width direction of the computer room, and arrange the mobile detection mechanism in segments according to the fixed plates in the length direction of the computer room, so that the nut blocks on the screw drive the camera body to move in the length direction of the computer room respectively;

[0022] Step 2: Establish a map model of the server distribution in the computer room, input the inspection route based on the map model, and control the mobile detection mechanism to move the camera body based on the inspection route;

[0023] Step 3: Based on the inspection route, set key locations to focus on; based on the distance between the key locations and the lead screw, input the control timing and rotation direction of the drive components; and simultaneously adjust the focal length of the lens group based on the distance between the key locations and the lead screw.

[0024] Step 4: Mark the fixed position of the fixed disk based on the map model. Based on the orientation relationship between the fixed position and the key focus position, adjust the rotation speed of the drive component according to the orientation relationship. This will increase the time the lens group spends facing the key focus position and shorten the time the lens group spends facing the non-key focus position. At the same time, adjust the focal length of the lens group based on the interval distance between the fixed position and the key focus position.

[0025] Furthermore, in step three, based on the key focus locations, the interval distance between the camera body and the key focus location at different locations in the inspection route is calculated. Based on the camera body with the shortest interval distance, abnormal execution instructions are added to the imaging mechanism according to the time period.

[0026] When the camera body switches to backup power, the actuator deviates towards the key focus area based on the abnormal execution command.

[0027] Furthermore, in step four, when there is personnel activity in the computer room, the movement position of the personnel in the map model is obtained, the camera body closest to the movement position is obtained, and a separate movement command is sent to the camera body closest to the movement position so that the camera body can follow the personnel.

[0028] The above approach has the following beneficial effects:

[0029] 1. This solution utilizes a linkage mechanism to drive the adjacent camera bodies to rotate, so that the movement directions of the adjacent cameras are staggered, thereby reducing the generation of blind spots in the field of view during monitoring and facilitating the accurate acquisition of external image data.

[0030] 2. In this solution, during continuous operation of the camera, under normal conditions, the circuit connection channel remains connected to the first contact, causing the electromagnet to operate and maintain the connection between the lens assembly and the imaging mechanism. This ensures external power supply and administrator access control. In the event of camera shutdown or external damage, the electromagnet shuts off, causing the lens assembly to fall downwards due to gravity. During the rotation of the lens assembly, the circuit connection channel connects to the second contact circuit, connecting the backup power supply and activating the imaging mechanism to continue acquiring external image data.

[0031] 3. In this solution, as the lens assembly falls downwards due to gravity, the lens assembly blocks the imaging mechanism to reduce the impact of projectiles from the ground onto the imaging mechanism. At the same time, the lens assembly is separated from the imaging mechanism to remove the obstruction from the imaging mechanism, thus facilitating the continued acquisition of external image data and enabling continuous monitoring of the information security of the computer room.

[0032] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] The following detailed description illustrates the specific implementation method:

[0045] As attached Figures 1 to 7 As shown: A computer network information security monitoring device includes several camera bodies arranged in a computer room. Each camera body includes a housing 1, an imaging mechanism 2 for acquiring external images, and a lens group 3 for adjusting the focus. Both the imaging mechanism 2 and the lens group 3 are existing technologies and will not be described in detail in this embodiment. The imaging mechanism 2 is located inside the housing 1. Adjacent camera bodies are fixedly connected by a linkage mechanism, which is used to make the movement directions of adjacent cameras rotate alternately.

[0046] The linkage mechanism includes a fixed detection mechanism and a mobile detection mechanism; the fixed detection mechanism includes several fixed panels 4, which are arranged in the four corners of the computer room. These fixed panels 4 in the four corners of the computer room facilitate the acquisition and processing of overall image data of the computer room via cameras, ensuring the coverage area is maximized.

[0047] A connecting roller 42 is rotatably fitted inside the fixed disk 4. A belt is clamped onto the connecting roller 42. A guide hole 41 is opened on one side of the fixed disk 4, and the belt is clearance-fitted with the guide hole 41. The moving detection mechanism includes a lead screw 5. A power component (in this embodiment, the power component is a motor) is coaxially fixedly connected to one end of the lead screw 5. A nut block 51 is slidably fitted on the lead screw 5. A connecting block 52 is fixedly connected to one side of the nut block 51. A driving component (in this embodiment, the driving component is a double-headed motor) is fixedly connected to the output shaft of the driving component. A connecting shaft 11 is rotatably fitted with the nut block 51, and one end of the connecting shaft 11 is fixedly connected to the outer shell 1. A locking block 12 is slidably fitted at the end of the connecting shaft 11 away from the connecting block 52. Several springs 13 are connected between the locking block 12 and the connecting shaft 11. The locking block 12 is located between the connecting roller 42 and the connecting shaft 11. A slot 43 for placing the locking block 12 is opened at the center of the connecting roller 42.

[0048] A guide groove 45 communicating with the slot 43 is opened on one side of the connecting roller 42. The end of the block 12 away from the connecting shaft 11 is arc-shaped. A magnet block 44 for adsorbing the block 12 is fixedly connected in the slot 43. In another embodiment, a magnetic layer with magnetic force is fixedly connected on the block 12. The magnet block 44 is a second electromagnet 33 with the opposite magnetic force to the magnetic layer. The repulsive force of the second electromagnet 33 is used to facilitate the separation of the block 12 from the slot 43, thereby facilitating the separation and installation of the block 12 from the connecting roller 42.

[0049] A connecting mechanism is provided between the imaging mechanism 2 and the lens group 3. The connecting mechanism includes a central shaft, a first contact 22 and a second contact 23. The first contact 22 and the second contact 23 are arranged vertically. The first contact 22 is connected to an external circuit, and the second contact 23 is electrically connected to a backup power supply located inside the housing 1. A circuit connection channel 34 for switching the imaging mechanism 2 to connect to the first contact 22 or the second contact 23 is fixedly connected to the lens group 3. The side of the lens group 3 closest to the imaging mechanism 2 is fixedly connected to the central shaft. An electromagnet 33 for attracting the imaging mechanism 2 is fixedly connected to the central shaft. The circuit connection channel 34 is located on both sides of the central shaft.

[0050] The imaging mechanism 2 has a groove 21 on the side near the lens group 3. The first contact 22 is located on the side of the groove 21 away from the lens group 3, and the second contact 23 is located on both sides of the groove 21. An extension block 32 is fixedly connected to the side of the lens group 3 near the imaging mechanism 2. The central shaft is fixedly connected to the extension block 32. The central shaft and the electromagnet 33 are both located in the groove 21, and the central shaft slides in the groove 21. The circuit connection channel 34 is located on the extension block 32. In this embodiment, the circuit connection channel 34 is fan-shaped.

[0051] When the lens assembly 3 is in its normal state, the extension block 32 blocks the slide groove 21, the circuit connection channel 34 is connected to the first contact 22, and the electromagnet 33 is activated; when the lens assembly 3 and the imaging mechanism 2 are in an interleaved state, the extension block 32 does not completely block the slide groove 21, the circuit connection channel 34 is connected to the second contact 23, and the electromagnet 33 is deactivated.

[0052] The specific implementation process is as follows:

[0053] During routine inspections, as the power component drives the lead screw 5 to rotate, the nut block 51 slides horizontally on the lead screw 5, enabling the tracking and imaging of servers in different locations within the server room. This facilitates taking pictures of servers in different areas. Simultaneously, the connecting block 52 drives the drive component and the camera body to rotate. As the nut block 51 moves horizontally on the lead screw 5, the drive component drives the connecting shaft 11 to rotate, causing the imaging mechanism 2 on the connecting shaft 11 to rotate around the connecting shaft 11, thus facilitating the acquisition of image data from different directions.

[0054] When the nut block 51 overlaps with the fixed plate 4, the compressed spring 13 pushes the locking block 12 into the slot 43, so that the connecting shaft 11 drives the connecting roller 42 to rotate through the locking block 12. Then, the adjacent connecting rollers 42 are connected by a belt to form a staggered rotation between adjacent positions. That is, although the adjacent connecting rollers 42 rotate clockwise, they are in a cross shape due to the different positions of the camera bases. They all rotate towards or away from the center line at the same time to reduce the blind spots between adjacent cameras.

[0055] During the process of maintaining the connection between the drive component and the connecting roller 42, the guide groove 45 communicates with the slot 43 to facilitate the entry of the connecting shaft 11 and the locking block 12 into the connecting roller 42, thereby facilitating the entry of the locking block 12 into the slot 43. At the same time, the arc-shaped locking block 12 is used to reduce the obstruction during the contact process between the locking block 12 and the connecting roller 42. The locking block 12 is then attracted by the magnet block 44, and the repulsive force of the spring 13 is combined to improve the stability of the locking block 12 and the connecting roller 42 when they are engaged, so that the connecting shaft 11 can drive the connecting roller 42 to rotate.

[0056] During continuous operation of the camera, under normal conditions, the electromagnet 33 is connected to the first contact 22 via the circuit connection channel 34, maintaining the connection between the lens assembly 3 and the imaging mechanism 2. This ensures external power supply and access to administrator control. In the event of external damage or when administrator control is disabled, the electromagnet 33 ceases to attract the imaging mechanism 2. The lens assembly 3 moves along the slide 21 due to its own weight. After sliding a certain distance, the lens assembly 3 rotates downwards around its central axis due to its own weight, connecting to the second contact 23 via the circuit connection channel 34. This connects the imaging mechanism 2 to the backup power supply, allowing the camera to continuously acquire external images without being affected by administrator access restrictions.

[0057] Meanwhile, as the lens group 3 falls downwards due to gravity, it blocks the imaging mechanism 2 to reduce the impact of projectiles from the ground onto the imaging mechanism 2. At the same time, the lens group 3 separates from the imaging mechanism 2 to remove the obstruction from the imaging mechanism 2, thus facilitating the continued acquisition of external image data and enabling continuous monitoring of the information security of the computer room.

[0058] In another embodiment, ventilation channels 31 are connected to both sides of the lens assembly 3. One end of the ventilation channel 31 is located on the side of the extension block 32 closer to the imaging mechanism 2, and the other end of the ventilation channel 31 is located on the side of the lens assembly 3 away from the imaging mechanism 2. The ventilation channels 31 enhance the heat exchange between the imaging mechanism 2 and the outside environment during operation, facilitating the transfer of heat generated by the imaging mechanism 2 to the outside environment, thereby enabling continuous heat dissipation of the camera body during continuous operation.

[0059] The ventilation channel 31 is also equipped with a photoresistor module for measuring the intensity of external light. The photoresistor module is electrically connected to the imaging mechanism 2. The imaging mechanism 2 is also used to compare the light intensity with the set standard value. If the light intensity is less than the standard value, an abnormal display command is sent to the outside. If the light intensity is greater than the standard value, a normal command is sent to the outside.

[0060] For example, in this embodiment, the outside world is a monitoring room with administrator privileges. By observing the obstruction of the lens group 3 by the outside world, changes in light intensity are generated to alert staff to the occurrence of abnormalities, enabling them to handle the situation in a timely manner. Alternatively, the electromagnet 33 can be controlled to stop working, causing the lens group 3 to drop downwards to remove the physical obstruction of the imaging mechanism 2 and ensure continuous acquisition of image data.

[0061] A computer network information security monitoring method, based on the above-mentioned computer network information security monitoring device, includes the following steps: Step 1: Manually arrange the fixed plates 4 in the four corners of the computer room, use belts to connect the fixed plates 4 in the width direction of the computer room, and arrange the moving detection mechanism in segments according to the fixed plates 4 in the length direction of the computer room, so that the nut blocks 51 on the lead screw 5 drive the camera body to move in the length direction of the computer room respectively.

[0062] Step 2: Establish a map model of the server distribution within the computer room, input the inspection route based on the map model, and control the mobile detection mechanism to move the camera body based on the inspection route.

[0063] Step 3: Based on the inspection route, set key locations to focus on. Based on the distance between the key locations and lead screw 5, input the control timing and rotation direction of the drive components. At the same time, based on the distance between the key locations and lead screw 5, adjust the focal length of lens group 3.

[0064] Furthermore, based on key locations of interest, the system calculates the distance between the camera body and the key locations of interest at different locations along the inspection route. Based on the camera body with the shortest distance, abnormal execution instructions are added to the imaging mechanism 2 according to time periods. When the camera body is switched to backup power, the drive unit deviates towards the key location of interest based on the abnormal execution instructions.

[0065] For example, by calculating the interval between the camera and the key locations during image acquisition by different cameras along the inspection route, and by adding abnormal execution instructions in advance, the cameras in different locations can continue to acquire image data of the key locations when abnormal situations occur. This provides graphic information protection for the information security monitoring of the computer room and facilitates subsequent filing, investigation or investigation as soon as possible.

[0066] Step 4: Based on the map model, mark the fixed position of the fixed disk 4. Based on the orientation relationship between the fixed position and the key focus position, adjust the rotation speed of the drive component according to the orientation relationship. This will increase the time that the lens group 3 faces the key focus position and shorten the time that the lens group 3 faces the non-key focus position. At the same time, adjust the focal length of the lens group 3 based on the interval distance between the fixed position and the key focus position.

[0067] When personnel are active within the server room, the system acquires their movement positions on the map model, identifies the nearest camera to that position, and sends a separate movement command to that camera to track and photograph the personnel. This tracking and photographing process enhances monitoring of personnel within the server room, reduces the risk of information leakage, provides data record-keeping, and offers sufficient information support for investigating information security vulnerabilities.

[0068] For example, during the operation of the camera itself and in routine inspections, key monitoring locations are set to ensure that the camera collects image data from these locations for extended periods during daily operation. This ensures sufficient data for information security monitoring, allowing for timely detection of anomalies and safeguarding the information security of the computer room. Simultaneously, adjusting the focal length of lens group 3 ensures the accuracy and clarity of image data acquisition, providing crucial data support for computer room monitoring.

[0069] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.

A method for monitoring computer network information security, characterized in that, The method of the computer network information security monitoring device according to any one of claims 1-7 includes the following steps: Step 1: The fixed plate (4) is manually arranged in the four corners of the computer room, and the fixed plate (4) between the width direction of the computer room is connected by belt. The moving detection mechanism is arranged in sections according to the fixed plate (4) between the length direction of the computer room, so that the nut block (51) on the screw (5) drives the camera body to move in the length direction of the computer room respectively. Step 2: Establish a map model of the server distribution in the computer room, input the inspection route based on the map model, and control the mobile detection mechanism to move the camera body based on the inspection route; Step 3: Based on the inspection route, set the key focus positions, and based on the distance between the key focus positions and the lead screw (5), input the control timing and rotation direction of the drive components, and at the same time, adjust the focal length of the lens group (3) based on the distance between the key focus positions and the lead screw (5). Step 4: Mark the fixed position of the fixed disk (4) based on the map model. Based on the orientation relationship between the fixed position and the key focus position, adjust the rotation speed of the drive component according to the orientation relationship. This will extend the time when the lens group (3) faces the key focus position and shorten the time when the lens group (3) faces the non-key focus position. At the same time, adjust the focal length of the lens group (3) based on the interval distance between the fixed position and the key focus position.

9. The computer network information security monitoring method according to claim 8, characterized in that, In step three, based on the key focus location, the interval distance between the camera body and the key focus location at different locations in the inspection route is calculated. Based on the camera body with the shortest interval distance, abnormal execution instructions are added to the imaging mechanism (2) according to the time period. When the camera body switches to backup power, the actuator deviates towards the key focus area based on the abnormal execution command.

10. The computer network information security monitoring method according to claim 8, characterized in that, In step four, when there is personnel activity in the computer room, the movement position of the personnel in the map model is obtained, the camera body closest to the movement position is obtained, and a separate movement command is sent to the camera body closest to the movement position so that the camera body can follow the personnel.
