[0015] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. The terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be a communication inside two elements.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0017] To clearly understand the technical solution of this application, the solutions of the prior art will be introduced in detail first. With the continuous expansion of the scale of data centers and the increasing number of devices, the importance of data operation and maintenance has been significantly improved. In the current operation and maintenance mode, operation and maintenance personnel need to go to the site to operate and maintain the devices. From the perspective of time and labor costs, on-site operation and maintenance requires operation and maintenance personnel to spend a lot of time traveling between different devices or data centers. Especially for large-scale data centers, the devices are widely distributed and numerous, and the time cost of a single on-site operation and maintenance is relatively high. At the same time, with the increase in the number of devices, the number of required operation and maintenance personnel also increases accordingly, resulting in an increase in labor costs. In terms of emergency response, when an emergency failure occurs in a device, operation and maintenance personnel need to rush to the site for handling. Affected by factors such as geographical location, it is difficult to achieve rapid response, which may lead to delays in fault handling, thereby affecting the normal operation of the device and the overall service quality of the data center. In addition, for the massive devices in large-scale data centers, the efficiency of manual inspection and maintenance is low, and it is easy to have omissions or operation errors, etc., affecting the accuracy and reliability of operation and maintenance.

[0018] To solve the above technical problems, the inventor thought of designing a device management system. Through the network communication between the management terminal and the control main board, the operation and maintenance operations are transferred from the site to remote execution; a dual-path management and control system for power management and operation management is constructed. Power management realizes remote regulation and real-time monitoring of the power supply status through the switch control module and the current detection module. Operation management converts the device operation control instructions into operation signals recognizable by the devices to be managed through the control signal processing module, thereby greatly shortening the single operation response time, reducing labor costs, improving the emergency failure response efficiency, and effectively ensuring the reliability of device operation and maintenance.

[0019] To enable those skilled in the art of this technology to better understand the solution of this application, the following will further elaborate on this application in combination with the accompanying drawings and specific implementation manners.

[0020] Refer to Figure 1 , Figure 1 which is the structural schematic Figure 1 of the device management system provided by the embodiment of this application. Figure 1 As shown in

[0021] The management terminal 101 is communicatively connected to the control main board 102 through the network.

[0022] Among them, the management terminal 101 serves as the interaction entry of the device management system, providing an operation display interface for the operation and maintenance personnel, instructing the user to send power control instructions and device operation instructions to the control main board 102 through the network, so as to realize the remote management operation of the device to be managed. At the same time, it receives and displays the device status information of the device to be managed fed back from the control main board 102, so as to facilitate the operation and maintenance personnel to grasp the operation status of the device to be managed in real time.

[0023] Among them, the control main board 102 serves as the core control hub of the device management system, undertaking the functions of instruction processing and scheduling. On the one hand, it communicates with the management terminal 101 through the network, receiving the power control instructions and device operation instructions from the management terminal; on the other hand, it respectively establishes communication connections with the switch control module 103 and the control signal processing module 107, and analyzes according to the instruction type. If it is a power control instruction, it controls the on / off of the switch control module 103; if it is a device operation control instruction, it forwards the device operation control instruction to the control signal processing module 107. In addition, it also receives the current data fed back by the current detection module 105 to judge whether the current of the device to be managed is abnormal.

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

[0025] The control main board 102 is communicatively connected to the control end of the switch control module 103.

[0026] Among them, the switch control module 103 is controlled by the control main board 102 and is responsible for controlling the on / off state of the power supply of the device to be managed. According to the power control instruction sent by the control main board 102, it realizes the conduction or disconnection operation of the circuit between the power processing module 104 and the power connection module 106, and then controls the power supply situation of the device to be managed. Exemplarily, it executes power operations such as turning on, turning off, and restarting the device to be managed.

[0027] Specifically, the control main board 102 is communicatively connected to the control end of the switch control module 103 through the switch control interface to realize the control of the switch control module 103, where the switch control interface is a GPIO interface (General-Purpose Input / Output).

[0028] The control main board 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] Among them, the control signal processing module 107 focuses on the processing and conversion of device operation control instructions. After receiving the device operation control instructions forwarded by the control main board 102, it analyzes the device operation control instructions and converts the device operation control instructions into operation signals recognizable by the device according to the interface protocol and signal standard of the device to be managed, such as electrical signals in a specific format, data protocol packets, etc.

[0030] Among them, the control signal connection module 108 serves as the physical communication bridge between the device management system and the device to be managed, and is responsible for transmitting the operation signals 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., 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 the status information fed back by 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 main board 102 is communicatively connected to the control signal processing module 107 through a control signal interface to realize the forwarding of device operation control instructions 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, and the current detection module 105 is also communicatively connected to the control main board 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 power input, responsible for accessing the input power, converting the unstable or power that does not meet the requirements of the device to be managed into a stable and adapted power output, and providing a reliable power supply basis for the subsequent switch control module 103, current detection module 105, power connection module 106 and the device to be managed.

[0035] Among them, the current detection module 105 is connected in series in the power supply circuit, used to monitor the magnitude of the current flowing through the power connection module 106 in real time, and transmit the detected current data to the control main board 102 in the form of a communication signal, so that the control main board 102 can judge the working state 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] Among them, the power connection module 106 serves as the interface unit for power transmission, stably delivering the power to the device to be managed, ensuring that the device to be managed obtains continuous and stable power and maintaining the normal operation of the device to be managed.

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

[0038] The management terminal 101 sends a power control instruction to the control main board 102 through the network, and the control main board 102 controls the on / 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 for 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 main board 102 through the network. After receiving the power control instruction, the control main board 102 first parses and verifies the power control instruction to confirm the legality of the power control instruction and the identifier of the device to be managed. If the verification passes, the control main board 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 on / off of the circuit between the power processing module 104 and the power connection module 106, and realizing the switching of the power state of the device to be managed.

[0040] The management terminal 101 sends a device operation control instruction to the control main board 102 through the network, and the control main board 102 forwards the device operation control instruction to the control signal processing module 107. The control signal processing module 107 converts the device operation control instruction into an operation signal recognizable 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 management terminal 101 over the device to be managed.

[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 the peripheral operation for the device to be managed, such as mouse movement and / or keyboard key presses. The management terminal 101 encapsulates the peripheral operation with a specific data protocol to obtain a device operation control instruction. The management terminal 101 sends the device operation control instruction to the control main board 102 through the network. The control main board 102 forwards the device operation control instruction to the control signal processing module 107. The control signal processing module 107 converts the device operation control instruction into an operation signal recognizable 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 management terminal 101 over the device to be managed.

[0042] Specifically, the working process of the embodiments of the present application further includes: the current detection module 105 monitors the current change in real time and feeds back the data to the control main board 102, so that the management terminal 101 synchronously displays the current state of the device to be managed.

[0043] As can be seen from the above embodiments, by constructing 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 state through the switch control module and the current detection module. The operation management converts the device operation control instruction into an operation signal recognizable by the device to be managed through the control signal processing module, and then transfers the operation and maintenance operation from the site to remote execution through the network communication between the management terminal and the control main board. This can greatly shorten the single operation response time, reduce the labor cost, improve the emergency fault response efficiency, and effectively ensure the reliability of device operation and maintenance.

[0044] Figure 2 The structural schematic of the device management system provided by the embodiment of the present 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 ends of the respective relay switches 103a.

[0046] The input ends of the respective relay switches 103a are electrically connected to the output end of the power processing module 104, the output ends of the respective relay switches 103a are electrically connected to the input end of the current detection module 105, and each relay switch 103a is used to control the on-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 states of multiple target devices in the device to be managed in parallel, and each relay switch 103a has an independent power supply channel to control the power supply state of the corresponding target device.

[0048] The working principle of each relay switch 103a is based on an electromagnetic or solid-state switch mechanism: when the control main board 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 contact to close, so that the stable direct current output by the power processing module 104 passes through the input end of the relay switch 103a, is transmitted to the output end of the relay switch 103a through the closed contact, and finally accesses the current detection module 105 to supply power to the device to be managed. When the control main board 102 outputs a low level, the coil of the relay switch 103a loses power, the contact disconnects, and the stable direct current path output by the power processing module 104 is cut off.

[0049] As can be seen from the above embodiments, the device management system supports remote operation of the relay switch without manual on-site intervention, effectively reducing the operation and maintenance labor cost. In addition, by virtue of the electromagnetic isolation characteristics of the relay switch, the power supply of the target device is controlled through the power control signal, realizing the effective isolation of the weak electrical signal output by the control main board from the strong electrical power of the target device, avoiding damage to the control circuit caused by strong electrical interference, and improving the reliability of the device management system.

[0050] Continuing to refer to 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 105a is electrically connected to the corresponding relay switch 103a, and the output end of each current detection resistor 105a is electrically connected to the device to be managed through the power connection module 106.

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

[0053] The positive input terminal of each differential amplifier 105b is electrically connected to one end of the corresponding current detection resistor 105a, and the negative 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 working, current flows through the current detection resistor to generate a small voltage difference. This small voltage difference is collected by the differential amplifier 105b, and the differential amplifier 105b is responsible for amplifying the small voltage difference generated by the current detection resistor 105a into an analog voltage signal within the standard voltage range recognizable by the analog-to-digital converter 105c.

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

[0056] Specifically, the analog-to-digital converter 105c converts the analog voltage signal output by the differential amplifier 105b into a digital quantity and transmits it to the control main board 102 through the communication control interface. The communication control interface is an SPI interface.

[0057] Continuing to refer to Figure 2 , the power processing module 104 includes: a filter 104a and an AC-DC converter 104b.

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

[0059] Specifically, the filter 104a is directly connected to an external input power supply, such as a 220V AC mains power supply. The electromagnetic interference filtering circuit inside the filter 104a filters out the clutter interference in the power grid to ensure the purity of the input power supply. The filtered power supply enters the AC-DC converter 104b, which converts the alternating current into direct current suitable for use by the device to be managed.

[0060] The output end of the AC-DC converter 104b is electrically connected to the input ends of the respective relay switches 103a.

[0061] Specifically, the output end of the AC-DC converter 104b is connected to the input ends of multiple 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 the device suddenly malfunctions, the current detection resistor captures the current mutation in real time, the differential amplifier quickly amplifies the tiny voltage difference, the analog-to-digital converter converts the analog signal into a digital quantity, and it is transmitted to the control main board through the communication control interface. The built-in anomaly detection algorithm of the control main board immediately identifies faults such as overcurrent and short circuit, and cuts off the power supply of the faulty device through the relay switch of the switch control module to prevent the spread of the fault. At the same time, the system automatically sends an alarm message to the management terminal and locates the identification of the faulty device. The operation and maintenance personnel can remotely view the device operation data and fault logs, quickly formulate a processing plan, and do not need to go to the site, effectively reducing the risk of device damage and the loss of business interruption.

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

[0064] Among them, the control signal processing module 107, as the core unit for realizing device operation and data interaction in the device management system, adopts a function-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 instructions.

[0065] The video signal processing unit 107a is communicatively connected to the control signal connection module 108; the video signal processing unit 107a is communicatively connected to 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 communicatively connected to the control main board 102, receiving both the processing and transmission instructions issued by the control main board 102 and returning the processed video data.

[0067] The peripheral signal processing unit 107b is communicatively connected to the control signal connection module 108; the peripheral signal processing unit 107b is communicatively connected to the control main board 102.

[0068] Specifically, the peripheral signal processing unit 107b establishes a bidirectional communication path. It is communicatively connected to 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 main board 102 to receive the peripheral control instructions forwarded by the control main board 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. The video signal processing unit 107a processes the original video signal to obtain a digital video stream. The control main board 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 a digital video signal collected 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 is built-in with a decoder and an encoding algorithm to perform noise reduction, format conversion, compression, etc. on the original video signal, and convert it into a digital video stream convenient for network transmission, such as the H.264 encoding format. After the processing is completed, the control main board 102 controls the video signal processing unit 107a to send the digital video stream to the management terminal 101 through the network according to the request of the management terminal 101, realizing remote real-time monitoring of the device video picture.

[0072] The management terminal 101 sends a peripheral control instruction to the control main board 102 through the network. The control main board 102 forwards the peripheral control instruction to the peripheral signal processing unit 107b. After processing the peripheral control instruction, the peripheral signal processing unit 107b sends it to the device to be managed through the control signal connection module 108 to realize the peripheral operation control of the management terminal 101 over the device to be managed.

[0073] Specifically, when an operation and maintenance personnel inputs a peripheral control instruction, such as a mouse action or a keyboard key, on the management terminal 101, the peripheral control instruction is transmitted to the control main board 102 through the network. After the control main board 102 parses the instruction, it forwards the instruction to the peripheral signal processing unit 107b. The peripheral signal processing unit 107b re-encodes, verifies, and processes the control instruction according to the interface protocol and instruction format of the peripheral of the device to be managed. Exemplarily, the general instruction is converted into a USB protocol, and the processed instruction is transmitted to the device to be managed through the control signal connection module 108, driving the peripheral to perform corresponding operations, thereby realizing the remote control of the peripheral of the device to be managed by the management terminal 101.

[0074] Continue to refer to 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 108a is communicatively connected to the video signal processing unit 107a, and each video control connection interface 108a is used for transmitting video streams.

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

[0077] Specifically, each video control connection interface 108a is directly communicatively connected to the video input / 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 for transmitting peripheral operation instructions.

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

[0080] Specifically, the peripheral control connection interface 108b is communicatively connected to the peripheral signal processing unit 107b as a transmission channel for peripheral operation instructions. When the peripheral signal processing unit 107b receives the peripheral control instruction forwarded by the control main board 102 and completes the instruction format conversion and processing, the instruction is transmitted to the peripheral input / output interface of the device to be managed through this peripheral control connection interface 108b in a specific protocol, and at the same time, the status information fed back by the peripheral of the device to be managed is transmitted back to the management terminal 101.

[0081] Refer to Figure 3 , Figure 3 is the structural schematic diagram of the device management system provided by the embodiment of the present application Figure 3 , such as Figure 3As shown in the figure, the video signal processing unit 107a includes a video amplifier 107a1 and a video encoder 107a2.

[0082] The video amplifier 107a1 is communicatively connected to each video control connection interface 108a; the video amplifier 107a1 is communicatively connected to the video encoder 107a2, and the video amplifier 107a1 is used to enhance the signal of the digital video stream.

[0083] Specifically, the video amplifier 107a1 establishes a communication connection with each video control connection interface 108a and receives the original digital video stream from the device to be managed. Since the signal may be attenuated, noise interfered, etc. during the transmission process, the video amplifier 107a1 performs signal enhancement processing on the digital video stream through the built-in amplification circuit and filtering algorithm, improves the picture brightness, contrast and clarity, and suppresses noise at the same time to ensure the quality of the video signal. The processed signal is transmitted to the video encoder 107a2 through the internal communication link.

[0084] The video encoder 107a2 is communicatively connected to the control main board 102, and the video encoder 107a2 is used to convert the video signal after signal enhancement into a digital video stream.

[0085] Specifically, the video encoder 107a2 is directly communicatively connected to the control main board 102 and receives the video signal after signal enhancement from the video amplifier 107a1. The video encoder 107a2 is an H.264 video encoder, and through the H.264 encoding algorithm, it is converted into a digital video stream format suitable for network transmission. During the encoding process, the video encoder 107a2 compresses the video data, reduces the data volume on the premise of ensuring the picture quality, and reduces the network transmission pressure. The encoded digital video stream is sent to the management terminal 101 through the network according to the instructions of the control main board 102, realizing the remote real-time display and monitoring of the device video picture.

[0086] It can be seen from the above embodiments that the video amplifier and the video encoder of the video signal processing unit work together to enhance and compress the original video signal into a low-bandwidth digital stream, enabling the operation and maintenance personnel to remotely obtain the high-definition device picture through the management terminal without on-site inspection, reducing the labor cost. In addition, when the video monitoring detects an equipment abnormality, the management terminal can cut off the relay switch through the control main board, thereby improving the emergency response time.

[0088] S401: The control main board monitors the control operation events of the management terminal in real time. When it monitors the control operation of the management terminal on the device to be managed, it obtains the operation control instruction corresponding to the control operation.

[0089] S402: The control main board analyzes 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 identifier of the device to be managed and the power setting status from the operation control instruction.

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

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

[0093] Sa1: If the power setting status indicates power on, control the relay switch corresponding to the device to be managed to conduct according to the device identifier.

[0094] Sa2: If the power setting status indicates power off, control the relay switch corresponding to the device to be managed to disconnect according to the device identifier.

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

[0096] S406: The control main board forwards the device identifier 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 / output interface of the device to be managed through the peripheral control connection interface to implement the operation control of the management terminal on the device to be managed.

[0098] As can be seen from the above embodiments, by constructing a dual-path management control system for power management and operation management, power management realizes remote regulation and real-time monitoring of the power supply status through the switch control module and the current detection module. Operation management converts the device operation control instruction into an operation signal recognizable by the device to be managed through the control signal processing module, and then through the network communication between the management terminal and the control main board, transfers the operation and maintenance operation from the site to remote execution, which can greatly shorten the single operation response time, reduce the labor cost, improve the emergency fault response efficiency, and effectively ensure the reliability of device operation and maintenance.

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

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

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

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

[0103] S504: The control main board 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 for 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 embodiments, the video amplifier and the video encoder of the video signal processing unit work together to enhance and compress the original video signal into a low-bandwidth digital stream, enabling the operation and maintenance personnel to remotely obtain the high-definition device screen through the management terminal without on-site inspection, thus reducing the labor cost. In addition, when the video monitoring detects device anomalies, the management terminal can cut off the relay switch through the control main board, thereby improving the emergency response time.
