Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0017] In order to clearly understand the technical solution of the present application, the solution of the prior art is first introduced in detail. With the continuous expansion of the scale of data centers and the increasing number of equipment, the importance of data operation and maintenance has increased significantly. In the current operation and maintenance model, operation and maintenance personnel need to go to the site to operate and maintain the equipment. From the perspective of time and labor costs, on-site operation and maintenance requires operation and maintenance personnel to invest a lot of time to travel back and forth between different equipment or data centers. Especially for large-scale data centers, the equipment is widely distributed and large in number, and the time cost of a single on-site operation and maintenance is relatively high. At the same time, as the number of equipment increases, the number of operation and maintenance personnel required also increases accordingly, resulting in an increase in labor costs. In terms of emergency response, when an emergency failure occurs in the equipment, the operation and maintenance personnel need to rush to the site to deal with it. Due to factors such as geographical location, it is difficult to achieve a quick response, which may cause delays in fault handling, thereby affecting the normal operation of the equipment and the overall service quality of the data center. In addition, for the massive equipment in large-scale data centers, the efficiency of manual inspection and maintenance is low, and it is easy to miss or make operational errors, which affects the accuracy and reliability of operation and maintenance.

[0018] In order to solve the above technical problems, the inventors came up with the idea of ​​designing an equipment management system, which transfers operation and maintenance operations from on-site to remote execution through network communication between the management terminal and the control mainboard; constructs a dual-path management and control system for power management and operation management. The power management realizes remote regulation and real-time monitoring of the power supply status through the switch control module and the current detection module. The operation management converts the equipment operation control instructions into operation signals that can be recognized by the managed equipment through the control signal processing module, thereby greatly shortening the response time of a single operation, reducing labor costs, improving the efficiency of emergency fault response, and effectively ensuring the reliability of equipment operation and maintenance.

[0019] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0020] refer to Figure 1 , Figure 1 Schematic diagram of the structure of the device management system provided in the embodiment of the application Figure 1 .like Figure 1 As shown, the device management system includes: a management terminal 101, a control mainboard 102, a switch control module 103, a power processing module 104, a current detection module 105, a power connection module 106, a control signal processing module 107 and a control signal connection module 108.

[0021] The management terminal 101 is connected to the control mainboard 102 via a network.

[0022] The management terminal 101 serves as the interactive portal to the device management system, providing an operational display interface for operations personnel. It instructs users to send power control and device operation instructions to the control board 102 via the network, enabling remote management of managed devices. It also receives and displays device status information from the control board 102, allowing operations personnel to monitor the operating status of managed devices in real time.

[0023] The control board 102 serves as the core control hub of the device management system, responsible for command processing and dispatching. It communicates with the management terminal 101 via the network, receiving power control commands and device operation commands from it. It also establishes communication connections with the switch control module 103 and the control signal processing module 107, parsing the commands based on their type. If the command is a power control command, it switches the switch control module 103 on and off; if it is a device operation control command, it forwards the command to the control signal processing module 107. Furthermore, it receives current data from the current detection module 105 to determine whether the current flow of the managed device is abnormal.

[0024] Specifically, the control motherboard 102 is an embedded motherboard based on the ARM architecture (Advanced RISC Machines, a reduced instruction set processor architecture). The management terminal 101 is connected to the Ethernet controller via the network, and the Ethernet controller is connected to the processor of the control motherboard 102 via the SPI (Serial Peripheral Interface).

[0025] The control mainboard 102 is in communication with the control terminal of the switch control module 103 .

[0026] The switch control module 103 is controlled by the control motherboard 102 and is responsible for controlling the power on / off status of the managed devices. Based on power control commands sent by the control motherboard 102, it switches the circuit between the power processing module 104 and the power connection module 106 on or off, thereby controlling the power supply to the managed devices. For example, it performs power operations such as powering on, off, and restarting the managed devices.

[0027] Specifically, the control mainboard 102 is connected to the control terminal of the switch control module 103 via a switch control interface to control the switch control module 103 , wherein the switch control interface is a GPIO interface (General-Purpose Input / Output).

[0028] The control mainboard 102 is communicatively connected to the control signal processing module 107 and the control signal connection module 108 in sequence, and the control signal connection module 108 is communicatively connected to the device to be managed.

[0029] The control signal processing module 107 is responsible for processing and converting device operation control commands. After receiving device operation control commands forwarded by the control mainboard 102, it parses the commands and, based on the interface protocols and signal standards of the managed devices, converts them into operational signals recognizable by the devices, such as electrical signals or data protocol packets in a specific format.

[0030] Among them, the control signal connection module 108 serves as a physical communication bridge between the device management system and the device to be managed. It is responsible for transmitting the operation signal processed by the control signal processing module 107 to the device to be managed through an adapted physical interface such as USB (Universal Serial Bus), etc., so as to realize the remote operation control of the device to be managed by the management terminal 101. At the same time, it can also receive status information feedback from the device to be managed and transmit it back to the control signal processing module 107 and the control main board 102.

[0031] Specifically, the control mainboard 102 is connected to the control signal processing module 107 via a control signal interface to forward the device operation control instruction to the control signal processing module 107. The control signal interface is a GPIO interface.

[0032] The power processing module 104 , the switch control module 103 , the current detection module 105 and the power connection module 106 are electrically connected in sequence. The current detection module 105 is also communicatively connected to the control mainboard 102 .

[0033] The power connection module 106 is electrically connected to the device to be managed.

[0034] Among them, the power processing module 104 is the front-end processing unit of the power input, which is responsible for accessing the input power and converting unstable power or power that does not meet the requirements of the managed device into a stable and adaptive power output, providing a reliable power supply foundation for the subsequent switch control module 103, current detection module 105, power connection module 106 and the managed device.

[0035] Among them, the current detection module 105 is connected in series in the power supply circuit, and is used to monitor the current flowing through the power connection module 106 in real time, and transmit the detected current data to the control motherboard 102 in the form of a communication signal, so that the control motherboard 102 can judge the working status of the device to be managed by analyzing the current data, such as whether there are abnormal conditions such as overload and short circuit.

[0036] The power connection module 106 serves as an interface unit for power transmission, stably delivering power to the managed device, ensuring that the managed device obtains continuous and stable power and maintains normal operation of the managed device.

[0037] Based on the structural connection relationship of the device management system, the working process of the embodiment of the present application is as follows:

[0038] The management terminal 101 sends a power control instruction to the control mainboard 102 via the network. The control mainboard 102 controls the on and off of the switch control module 103 according to the power control instruction.

[0039] Specifically, the operator of the management terminal 101 selects the device to be managed on the display interface of the device management software, and selects the power operation of the device to be managed, such as power on, power off or restart. The management terminal 101 encapsulates the power operation with a specific data protocol to obtain a power control instruction. The management terminal 101 transmits it to the control mainboard 102 through the network. After receiving the power control instruction, the control mainboard 102 first parses and verifies the power control instruction to confirm the legitimacy of the power control instruction and the identification of the device to be managed. If the verification is successful, the control mainboard 102 generates a corresponding electrical signal control code and sends it to the switch control module 103 through the switch control interface. After receiving the electrical signal control code, the switch control module 103 performs a conduction or disconnection action, thereby controlling the circuit between the power processing module 104 and the power connection module 106, and realizing the power state switching of the device to be managed.

[0040] The management terminal 101 sends device operation control instructions to the control main board 102 through the network. The control main board 102 forwards the device operation control instructions to the control signal processing module 107. The control signal processing module 107 converts the device operation control instructions into an operation signal that can be recognized by the device to be managed, and transmits the operation signal to the device to be managed through the control signal connection module 108, so as to realize the operation control of the device to be managed by the management terminal 101.

[0041] Specifically, the operator of the management terminal 101 selects the device to be managed on the display interface of the device management software and selects peripheral operations for the device to be managed, such as mouse movements and / or keyboard keys. The management terminal 101 encapsulates the peripheral operations using a specific data protocol to obtain device operation control instructions. The management terminal 101 sends the device operation control instructions to the control mainboard 102 via the network. The control mainboard 102 forwards the device operation control instructions to the control signal processing module 107. The control signal processing module 107 converts the device operation control instructions into operation signals that can be recognized by the device to be managed and transmits the operation signals to the device to be managed via the control signal connection module 108, thereby realizing the operation control of the device to be managed by the management terminal 101.

[0042] Specifically, the working process of the embodiment of the present application also includes: the current detection module 105 monitors the current changes in real time and feeds back the data to the control mainboard 102, so that the management terminal 101 synchronously displays the current status of the device to be managed.

[0043] It can be seen from the above embodiments that by constructing a dual-path management and control system of power management and operation management, power management realizes remote control and real-time monitoring of the power supply status through the switch control module and the current detection module, and operation management converts the equipment operation control instructions into operation signals that can be recognized by the managed equipment through the control signal processing module, and then transfers the operation and maintenance operations from the site to remote execution through the network communication between the management terminal and the control mainboard, which can greatly shorten the response time of a single operation, reduce labor costs, improve the efficiency of emergency fault response, and effectively ensure the reliability of equipment operation and maintenance.

[0044] Figure 2 Schematic diagram of the structure of the device management system provided in the embodiment of the application Figure 2 ,refer to Figure 2 The switch control module 103 in the above embodiment includes: a plurality of relay switches 103a.

[0045] The control main board 102 is electrically connected to the control end of each relay switch 103 a.

[0046] The input end of each relay switch 103a is electrically connected to the output end of the power processing module 104, and the output end of each relay switch 103a is electrically connected to the input end of the current detection module 105. Each relay switch 103a is used to control the on and off of the current in the loop where each relay switch 103a is located.

[0047] Specifically, the switch control module 103 can control the power supply status of multiple target devices in the managed device in parallel, and each relay switch 103a has an independent power supply channel to control the power supply status of the corresponding target device.

[0048] The operating principle of each relay switch 103a is based on an electromagnetic or solid-state switching mechanism: when the control motherboard 102 outputs a high level or a specific pulse signal through the switch control interface, the coil of the relay switch 103a is energized to generate a magnetic field, driving the contacts to close. This allows the stable DC power output by the power processing module 104 to be transmitted through the input terminal of the relay switch 103a, through the closed contacts, to the output terminal of the relay switch 103a, and ultimately to the current detection module 105, thereby powering the managed device. When the control motherboard 102 outputs a low level, the coil of the relay switch 103a is de-energized, the contacts open, and the stable DC power path output by the power processing module 104 is cut off.

[0049] As can be seen from the above examples, the device management system supports remote operation of relay switches, eliminating the need for on-site manual intervention and effectively reducing maintenance costs. Furthermore, leveraging the electromagnetic isolation characteristics of relay switches, the target device's power supply can be controlled via power control signals. This effectively isolates the weak current output of the control motherboard from the strong current of the target device's power supply, preventing strong current interference from damaging the control circuit and improving the reliability of the device management system.

[0050] Continue to refer Figure 2 The current detection module 105 includes: a plurality of current detection resistors 105a, a plurality of differential amplifiers 105b and an analog-to-digital converter 105c.

[0051] The input end of each current detection resistor 105 a is electrically connected to the corresponding relay switch 103 a , and the output end of each current detection resistor 105 a is electrically connected to the device to be managed through the power connection module 106 .

[0052] Specifically, each current detection resistor 105 a is connected in series in the current path between the corresponding relay switch 103 a and the power connection module 106 .

[0053] The non-inverting input terminal of each differential amplifier 105b is electrically connected to one end of the corresponding current detection resistor 105a, and the inverting input terminal of each differential amplifier 105b is electrically connected to the other end of the corresponding current detection resistor 105a; the output terminal of each differential amplifier 105b is electrically connected to the analog-to-digital converter 105c.

[0054] Specifically, when the device is operating, current flowing through the current detection resistor generates a small voltage difference, which is collected by the differential amplifier 105b, which is responsible for amplifying the small voltage difference generated by the current detection resistor 105a into an analog voltage signal within a standard voltage range that can be recognized by the analog-to-digital converter 105c.

[0055] The output terminal of the analog-to-digital converter 105 c is connected to the control mainboard 102 .

[0056] Specifically, the analog-to-digital converter 105c converts the analog voltage signal output by the differential amplifier 105b into a digital value, and transmits the digital value to the control mainboard 102 via the communication control interface, which is an SPI interface.

[0057] Continue to refer Figure 2 The power processing module 104 includes a filter 104a and an AC-DC converter 104b.

[0058] The filter 104 a is connected to an input power supply, and an output end of the filter 104 a is electrically connected to an input end of the AC / DC converter 104 b.

[0059] Specifically, filter 104a is directly connected to an external input power source, such as a 220V AC mains power source. The electromagnetic interference filtering circuit within filter 104a removes any interference from the power grid, ensuring the purity of the input power. The filtered power then enters AC / DC converter 104b, which converts the AC power into DC power suitable for the managed device.

[0060] The output end of the AC / DC converter 104 b is electrically connected to the input end of each relay switch 103 a .

[0061] Specifically, the output end of the AC / DC converter 104b is connected to the input ends of the plurality of relay switches 103a through a star wiring structure, and each branch is configured with an independent filter capacitor to stabilize the branch voltage.

[0062] As can be seen from the above embodiments, when a device experiences a sudden abnormality, the current detection resistor captures the current mutation in real time, the differential amplifier quickly amplifies the tiny voltage difference, and the analog-to-digital converter converts the analog signal into a digital quantity, which is then transmitted to the control mainboard via the communication control interface. The control mainboard's built-in abnormality detection algorithm immediately identifies faults such as overcurrent and short circuits, and cuts off the power supply to the faulty device through the relay switch of the switch control module to prevent the fault from spreading. At the same time, the system automatically sends an alarm message to the management terminal and locates the faulty device identifier. Operations and maintenance personnel can remotely view equipment operating data and fault logs and quickly develop a solution without having to rush to the site, effectively reducing the risk of equipment damage and business interruption losses.

[0063] Continue to refer Figure 2 The control signal processing module 107 includes: a video signal processing unit 107a and a peripheral signal processing unit 107b.

[0064] The control signal processing module 107, the core unit for implementing device operations and data interaction within the device management system, employs a functionally separated architecture and is divided into a video signal processing unit 107a and a peripheral signal processing unit 107b. The video signal processing unit 107a focuses on the acquisition, processing, and transmission of device video data, while the peripheral signal processing unit 107b is responsible for parsing and executing peripheral control commands.

[0065] The video signal processing unit 107 a is in communication connection with the control signal connection module 108 ; the video signal processing unit 107 a is in communication connection with the control main board 102 .

[0066] Specifically, the video signal processing unit 107a constructs a two-way communication link in the device management system. One end is connected to the device to be managed through the control signal connection module 108 to receive the original video signal output by the device to be managed; the other end is communicated with the control main board 102, and it not only receives the processing and transmission instructions issued by the control main board 102, but also transmits the processed video data back.

[0067] The peripheral signal processing unit 107 b is in communication connection with the control signal connection module 108 ; the peripheral signal processing unit 107 b is in communication connection with the control main board 102 .

[0068] Specifically, the peripheral signal processing unit 107b establishes a two-way communication path, which is communicated with the control signal connection module 108 as an output channel for sending control instructions to the device to be managed; at the same time, it is connected to the control mainboard 102 to receive the peripheral control instructions forwarded by the control mainboard 102.

[0069] Based on the structural connection relationship of this embodiment, the working process of this embodiment is as follows:

[0070] The device to be managed transmits the original video signal to the control signal connection module 108, and the video signal processing unit 107a processes the original video signal to obtain a digital video stream. The control mainboard 102 controls the video signal processing unit 107a to send the digital video stream to the management terminal 101 through the network.

[0071] Specifically, when the device to be managed generates an original video signal, such as an analog video stream or digital video signal captured by a camera, the original video signal is first transmitted to the control signal connection module 108 and then sent to the video signal processing unit 107a. The video signal processing unit 107a has a built-in decoder and encoding algorithm to perform noise reduction, format conversion, compression and other processing on the original video signal, converting it into a digital video stream that is convenient for network transmission, such as the H.264 encoding format. After processing is completed, the control motherboard 102 controls the video signal processing unit 107a to send the digital video stream to the management terminal 101 via the network based on the request of the management terminal 101, thereby realizing remote real-time monitoring of the device video screen.

[0072] The management terminal 101 sends peripheral control instructions to the control main board 102 through the network. The control main board 102 forwards the peripheral control instructions to the peripheral signal processing unit 107b. The peripheral signal processing unit 107b processes the peripheral control instructions and sends them to the device to be managed through the control signal connection module 108, so as to realize the peripheral operation control of the device to be managed by the management terminal 101.

[0073] Specifically, when an operation and maintenance personnel inputs a peripheral control instruction, such as a mouse movement or keyboard keystroke, into the management terminal 101, the peripheral control instruction is transmitted via the network to the control mainboard 102. After parsing the instruction, the control mainboard 102 forwards it to the peripheral signal processing unit 107b. Peripheral signal processing unit 107b re-encodes and verifies the control instruction based on the interface protocol and instruction format of the peripheral device to be managed. For example, the unit converts the general instruction into a USB protocol. The processed instruction is then transmitted to the managed device via the control signal connection module 108, driving the peripheral device to perform the corresponding operation, thereby enabling the management terminal 101 to remotely control the peripheral device to be managed.

[0074] Continue to refer Figure 2 The control signal connection module 108 includes: a plurality of video control connection interfaces 108a and a plurality of peripheral control connection interfaces 108b.

[0075] Each video control connection interface 108 a is communicatively connected to the video signal processing unit 107 a , and each video control connection interface 108 a is used to transmit a video stream.

[0076] Each video control connection interface 108a is communicatively connected to a video input and output interface of a device to be managed.

[0077] Specifically, each video control connection interface 108a is directly connected to the video input and output interface of the device to be managed, and is responsible for transmitting the original video signal generated by the device to be managed to the video signal processing unit 107a.

[0078] Each peripheral control connection interface 108b is communicatively connected to the peripheral signal processing unit 107b, and each peripheral control connection interface 108b is used to transmit peripheral operation instructions.

[0079] Each peripheral control connection interface 108b is communicatively connected to the peripheral input and output interface of the device to be managed.

[0080] Specifically, the peripheral control connection interface 108b is in communication with the peripheral signal processing unit 107b, serving as a transmission channel for peripheral operation instructions. When the peripheral signal processing unit 107b receives the peripheral control instruction forwarded by the control mainboard 102 and completes the instruction format conversion and processing, it transmits the instruction to the peripheral input and output interface of the managed device through the peripheral control connection interface 108b using a specific protocol. At the same time, it transmits the status information fed back by the peripheral device to the management terminal 101.

[0081] refer to Figure 3 , Figure 3 Schematic diagram of the structure of the device management system provided in the embodiment of the application Figure 3 ,like Figure 3As shown, the video signal processing unit 107a includes a video amplifier 107a1 and a video encoder 107a2.

[0082] The video amplifier 107a1 is in communication with each video control connection interface 108a; the video amplifier 107a1 is in communication with the video encoder 107a2, and the video amplifier 107a1 is used to perform signal enhancement on the digital video stream.

[0083] Specifically, video amplifier 107a1 establishes a communication connection with each video control interface 108a to receive the raw digital video stream from the managed device. Because signal transmission may be subject to attenuation and noise interference, video amplifier 107a1 uses its built-in amplification circuit and filtering algorithm to enhance the digital video stream, improving image brightness, contrast, and clarity while suppressing noise to ensure video signal quality. The processed signal is then transmitted to video encoder 107a2 via an internal communication link.

[0084] The video encoder 107a2 is in communication with the control mainboard 102 and is used to convert the enhanced video signal into a digital video stream.

[0085] Specifically, video encoder 107a2 is directly connected to control board 102 and receives the amplified video signal from video amplifier 107a1. Video encoder 107a2 is an H.264 video encoder that uses the H.264 encoding algorithm to convert the video signal into a digital video stream format suitable for network transmission. During the encoding process, video encoder 107a2 compresses the video data, reducing data volume and network transmission pressure while maintaining image quality. The encoded digital video stream is then transmitted to management terminal 101 via the network according to instructions from control board 102, enabling remote real-time display and monitoring of the device's video feed.

[0086] As can be seen from the above embodiment, the video amplifier and video encoder in the video signal processing unit work together to enhance and compress the original video signal into a low-bandwidth digital stream. This allows maintenance personnel to remotely access high-definition device images through the management terminal, eliminating the need for on-site inspections and reducing labor costs. Furthermore, if video surveillance detects a device anomaly, the management terminal can control the mainboard to disconnect the relay, thereby improving emergency response time.

[0087] Figure 4 This is a flow chart of the device management method provided in the embodiment of the present application. Figure 4 As shown, the method includes:

[0088] S401: The control mainboard monitors the control operation events of the management terminal in real time, and when monitoring the control operation of the management terminal on the managed device, obtains the operation control instruction corresponding to the control operation.

[0089] S402: The control mainboard parses the operation control instruction to determine the operation type of the control operation, where the operation type includes power control and / or peripheral control.

[0090] S403: If the operation type is power control, extract the device identification and power setting status of the device to be managed from the operation control instruction.

[0091] S404: The control mainboard controls the on / off of the relay switch corresponding to the device to be managed according to the device identification and the power setting status.

[0092] Specifically, the process includes Sa1~Sa2:

[0093] Sa1: If the power setting status indicates that the power is turned on, the relay switch corresponding to the device to be managed is controlled to be turned on according to the device identification.

[0094] Sa2: If the power setting status indicates that the power is turned off, the relay switch corresponding to the device to be managed is controlled to be disconnected according to the device identification.

[0095] S405: If the operation type is peripheral control, extract the device identification and operation data of the device to be managed from the operation control instruction.

[0096] S406: The control mainboard forwards the device identification and the operation data to the peripheral signal processing unit.

[0097] S407: The peripheral signal processing unit converts the operation data into a standardized instruction, and sends the standardized instruction to the peripheral input and output interface of the device to be managed through the peripheral control connection interface, so as to realize the operation control of the device to be managed by the management terminal.

[0098] It can be seen from the above embodiments that by constructing a dual-path management and control system of power management and operation management, power management realizes remote control and real-time monitoring of the power supply status through the switch control module and the current detection module, and operation management converts the equipment operation control instructions into operation signals that can be recognized by the managed equipment through the control signal processing module, and then transfers the operation and maintenance operations from the site to remote execution through the network communication between the management terminal and the control mainboard, which can greatly shorten the response time of a single operation, reduce labor costs, improve the efficiency of emergency fault response, and effectively ensure the reliability of equipment operation and maintenance.

[0099] In another embodiment of the present application, the management terminal further includes a process of remotely monitoring the video signal of the device to be managed, and the process includes:

[0100] S501: The device to be managed sends an original video signal to a video amplifier through a corresponding video control connection interface.

[0101] S502: The video amplifier performs signal enhancement processing on the original video signal to obtain a signal-enhanced video signal.

[0102] S503: The video encoder converts the enhanced video signal into a digital video stream.

[0103] S504: The control mainboard controls the video encoder to send the digital video stream to the management terminal through the network.

[0104] S505: In response to the video viewing operation on the device to be managed, the management terminal decodes the digital video stream to obtain an analog video signal, and displays the analog video signal on the display interface.

[0105] As can be seen from the above embodiment, the video amplifier and video encoder in the video signal processing unit work together to enhance and compress the original video signal into a low-bandwidth digital stream. This allows maintenance personnel to remotely access high-definition device images through the management terminal, eliminating the need for on-site inspections and reducing labor costs. Furthermore, if video surveillance detects a device anomaly, the management terminal can control the mainboard to disconnect the relay, thereby improving emergency response time.
