[0053] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the 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 of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0054] The terms "include" and "have" and any variations in the specification and above drawings of the present application, as well as any variations related to "include" and "have", are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can include steps or units not listed.

[0055] In order to enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0056] The conventional wired keyboard and mouse solution has problems such as complex wiring, multiple device occupation, and low operation efficiency across servers. The Bluetooth device management technology of a general terminal only focuses on the connection control of a general terminal and does not adapt to the special needs of a data center server.

[0057] 1. Signal interference problem: In a high-density deployment environment of a data center, multiple servers coexist at a close distance, and an ordinary Bluetooth signal is easily disturbed, with poor connection stability (usually < 90%);

[0058] 2. Authority and security vulnerability: The server pairing information is not stored and controlled by encryption, which cannot meet the requirements of operation audit and information security of a data center;

[0059] 3. Hardware cooperation is missing: not deeply integrated with the server hardware architecture (such as motherboard bus, BMC system), it is difficult to realize the low delay, intelligent start and stop and other data center exclusive functions.

[0060] To solve the above technical problems, the application discloses a Bluetooth keyboard and mouse management method, device, equipment and medium, which can adapt to the anti-interference Bluetooth connection of high-density deployment of data centers and adapt to multi-server scenarios.

[0061] Referring to Figure 1 The application embodiment provides a Bluetooth keyboard and mouse management method, which comprises the following steps:

[0062] In step S11, the start-stop state of the Bluetooth keyboard and mouse is determined according to the target data of the current server, and if the Bluetooth keyboard and mouse is started, the current server and the Bluetooth keyboard and mouse are connected through a high-speed serial computer expansion bus standard channel; the target data includes the central processor occupancy rate and the load state.

[0063] In the application embodiment, the Bluetooth keyboard and mouse can be woken up by pressing the key, that is, the Bluetooth keyboard and mouse is started. In a specific embodiment, the Bluetooth keyboard and mouse is started through a wake-up combination key (such as Ctrl+Alt+F12). After the Bluetooth keyboard and mouse is started, the central processor occupancy rate and the execution task of the current server are monitored in real time; if the central processor occupancy rate is less than or equal to a target threshold, the start state of the Bluetooth keyboard and mouse is maintained; if the central processor occupancy rate is greater than the target threshold or the load of the execution task of the current server is greater than a preset load threshold, the Bluetooth keyboard and mouse is closed, and the Bluetooth keyboard and mouse is restarted based on a preset time after the execution task of the current server is completed. Specifically, if the central processor occupancy rate is less than or equal to 80%, the start state of the Bluetooth keyboard and mouse is maintained, and if the central processor occupancy rate is greater than 80%, the Bluetooth keyboard and mouse is put into a waiting queue and is retried after 30 seconds, and the central processor occupancy rate and the execution task of the current server are determined again to see whether the connection can be established. The CPU occupancy rate and the memory usage rate of the server are monitored in real time, and when the CPU occupancy rate is greater than 80% or a high-load task is executed, the Bluetooth module is automatically closed to release hardware resources; the connection is restarted and restored within 30 seconds after the task is completed. In addition, in the application, the Bluetooth control module performs load monitoring and module start-stop during the normal operation of the server: the CPU occupancy rate and the memory usage rate are collected every 10 seconds, and the Bluetooth module is automatically started or stopped according to a preset threshold (such as the CPU occupancy rate being greater than 80%).

[0064] In the process of establishing a connection, the current server and the Bluetooth keyboard and mouse are connected through the high-speed serial computer expansion bus standard channel, and in the process of connecting the current server and the Bluetooth keyboard and mouse through the high-speed serial computer expansion bus standard channel, the frequency of the signal between the current server and the Bluetooth keyboard and mouse is adjusted through digital radio frequency technology to optimize the communication between the current server and the Bluetooth keyboard and mouse. That is, the application directly connects the server CPU through the PCIe (Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard, which is a channel for connecting the special Bluetooth communication module with the server CPU (Central Processing Unit, central processor) in the application to realize efficient data transmission), adopts DRF (Digital radio frequency, digital radio frequency) technology to optimize short-distance communication, supports dynamic adjustment of signal frequency (range 2.402-2.480GHz), and reduces the interference probability in the multi-server deployment scene. In this way, through the DRF technology and the PCIe direct connection architecture, the stability of the Bluetooth connection is further improved in the multi-server high-density deployment scene, and the problem of easy interference of the data center Bluetooth signal is solved.

[0065] Step S12, judging whether the current server and the Bluetooth keyboard and mouse are connected successfully according to target information; the target information includes the media access control address of the Bluetooth keyboard and mouse, the Internet protocol address of the server and the current operation and maintenance personnel number.

[0066] In the embodiment of the present application, the target operation and maintenance personnel number corresponding to the media access control address of the Bluetooth keyboard and mouse and the Internet protocol address of the server is determined according to the pre-set matching information; the target operation and maintenance personnel number and the current operation and maintenance personnel number are compared; if the target operation and maintenance personnel number and the current operation and maintenance personnel number are consistent, it is determined that the current server and the Bluetooth keyboard and mouse are connected successfully; if the target operation and maintenance personnel number and the current operation and maintenance personnel number are inconsistent, it is determined that the current server and the Bluetooth keyboard and mouse are connected unsuccessfully, the corresponding security log is generated, and alarm processing is performed; wherein the alarm processing includes turning on the local indicator light, the baseboard management controller system pop-up prompt and the operation and maintenance management platform email notification. In the present application, when the Bluetooth keyboard and mouse are used for the first time, the operation and maintenance personnel access the Bluetooth keyboard and mouse through the server local console, triggering the security pairing process. The Bluetooth communication module automatically collects the device MAC (Media Access Control Address, media access control address) address, the server IP (Internet Protocol, Internet Protocol), and the current operation and maintenance personnel number. Because the operation and maintenance personnel corresponding to each server are different, when operating, different operation and maintenance personnel are matched in advance according to the media access control address of the Bluetooth keyboard and mouse and the Internet protocol address of the server, so the pre-set operation and maintenance personnel number can be determined according to the media access control address of the Bluetooth keyboard and mouse and the Internet protocol address of the server, and then the pre-set operation and maintenance personnel number and the current operation and maintenance personnel number are compared to see if they match. If they match, the current server and the Bluetooth keyboard and mouse can be connected. If the current server and the Bluetooth keyboard and mouse are connected unsuccessfully, the corresponding security log is generated, and alarm processing is performed. In this process, the start / stop state of the Bluetooth module, fault information (such as communication interruption, encryption key exception) is synchronized to the BMC (Baseboard Management Controller, baseboard management controller, a dedicated microcontroller on the server, which is linked with the Bluetooth module in the present application, and the module state and fault information are synchronized to the health monitoring log, and the alarm is triggered when the module fails. ) Health monitoring log, supports remote SSH (Secure Shell, an encrypted network transmission protocol, which supports remote query of the state and fault information of the Bluetooth module through the protocol in the present application), Web console query; when the module fails, three-level alarm (local LED (light-emitting diode) indicator light flashing, BMC system pop-up, operation and maintenance management platform email notification) is automatically triggered.

[0067] In addition, the device MAC address, server IP, current operation personnel ID and other information automatically collected by the Bluetooth communication module in the application are encrypted by an SM4 algorithm and stored in an NVMe SSD (Non-Volatile Memory Express) based on an NVMe (Non-Volatile Memory Express) protocol solid state disk. The integrated encryption partition in the application is used to store the pairing information encrypted by the SM4 algorithm (a national encryption algorithm used for encryption processing of pairing information in the application, and the encryption key is bound to the server BMC to ensure information security). The encryption partition is also synchronized to the data center operation management platform for recordal.

[0068] In addition, when an abnormality such as Bluetooth communication interruption or encryption key check failure occurs, the current server and the Bluetooth keyboard and mouse are reconnected based on a preset time interval within a preset number of reconnection attempts. If the number of reconnection attempts is greater than a target number, an alarm processing operation is triggered. In a specific embodiment, the Bluetooth control module automatically attempts to reconnect (reconnection strategy: retry every 10 seconds for the first minute, retry every 30 seconds from the second minute, and a maximum of 10 retries). If the reconnection fails, the BMC system is triggered to alarm, and the Bluetooth module operation permission is locked (only the local console is allowed to unlock) to prevent unauthorized access

[0069] Step S13, after successful connection, the Bluetooth keyboard and mouse interact with the current server, if there is a switching connection request, the priority of each server is determined according to the priority of each server, the server to be connected is determined as the new current server, and the step of determining the start-stop state of the Bluetooth keyboard and mouse according to the target data of the current server is rejumped until the preset cycle end condition is met.

[0070] In the embodiment of the application, after successful connection, the Bluetooth keyboard and mouse interacts with the current server, but if there are multiple servers and the Bluetooth keyboard and mouse initiates a switching server connection request, the priority of the server to be connected needs to be determined according to the priority of each server determined in advance. In the application, if the current mode of the server is the operation mode, and the server load rate is less than the target load rate, the priority of the server is determined as the first priority; if the server does not perform a task meeting the preset condition, the priority of the server is determined as the second priority; if the priority of the task performed by the server meets the preset low priority condition, the priority of the server is determined as the third priority; the server with the first priority is determined as the server to be connected. Specifically, as shown in Figure 2 When a set of Bluetooth keyboard and mouse switches connection to multiple servers, the priority is dynamically allocated according to the server state:

[0071] Priority 1 (highest): servers in "operation and maintenance mode" and load rate < 30%;

[0072] Priority 2: servers in normal operation state and no critical tasks;

[0073] Priority 3: servers performing low-priority tasks (such as log backup).

[0074] When multiple servers request connection at the same time, the priority is scheduled to avoid connection interruption caused by signal contention (in this way, the connection stability in the multi-server scene is > 99.9%).

[0075] In addition, during the data transmission process of the Bluetooth keyboard and mouse and the server, the idle time of the Bluetooth keyboard and mouse is detected; if the idle time is greater than the first time, the Bluetooth keyboard and mouse is controlled to sleep; after triggering the preset start key, the Bluetooth keyboard and mouse is restarted based on the second time. Specifically, if the idle time of the Bluetooth keyboard and mouse is greater than 5 minutes, the Bluetooth keyboard and mouse is controlled to sleep, thereby reducing power consumption, or the Bluetooth keyboard and mouse is controlled to enter a low-power mode, and when the Bluetooth keyboard and mouse needs to be awakened, the Bluetooth keyboard and mouse can be awakened according to the wake-up combination key (such as Ctrl+Alt+F12).

[0076] It should be noted that the application can also embed an independent Bluetooth module in the server, which can be combined with the system and SSH (Secure Shell, Secure Shell) service, and a multi-modal remote control system can be constructed to expand the control capability of other servers. Bluetooth can be used as an auxiliary authentication channel for SSH, for example: the physical exchange of SSH keys is completed through Bluetooth near field communication (NFC, Near Field Communication), which avoids exposing public keys to the network; combined with two-factor authentication (such as Bluetooth device dynamic token + SSH password) to improve security. In a network-free environment, a temporary SSH tunnel can be established through Bluetooth pairing to realize localized maintenance. In an industrial server cluster, Bluetooth can quickly locate the fault node, and then perform deep debugging through SSH. Through this integration method, the management barriers between devices can be further broken down, and more flexible and efficient cross-server collaborative operation and maintenance can be realized, providing more possibilities for centralized and intelligent management of data center server clusters.

[0077] Beneficial effects: The application directly connects the central processing unit through the high-speed serial computer expansion bus standard channel, greatly reduces the signal interference in the multi-server high-density deployment scene, and improves the connection stability. According to the server state, the connection priority is dynamically allocated, and when multiple servers request connection, the priority is scheduled to realize fast switching and guarantee the connection stability. Furthermore, the Bluetooth keyboard and mouse are adapted to the multi-server application scene.

[0078] For example, Figure 3As shown, this invention discloses a specific Bluetooth keyboard and mouse management method, which enables Bluetooth keyboards and mice to adapt to multiple server application scenarios and solves the industry pain point of Bluetooth signals being easily interfered with in data centers. The specific Bluetooth keyboard and mouse management process will be explained from the perspective of a server system integrating a Bluetooth keyboard and mouse.

[0079] 1. Hardware Layer: Dedicated Bluetooth communication module embedded in the server motherboard: Directly connected to the server CPU via the PCIe channel, using DRF technology to optimize short-range communication, supporting dynamic signal frequency adjustment (range 2.402-2.480GHz), reducing the probability of interference in multi-server deployment scenarios. Non-volatile storage unit (NVMe SSD integrated encrypted partition): Used to store encrypted pairing information (including server IP, Bluetooth device MAC address, and maintenance personnel permission identifier), encrypted using the SM4 national cryptographic algorithm, with the key bound to the server BMC (Baseboard Management Controller).

[0080] 2. Hardware Layer: Bluetooth Control Module (Deployed in the server OS kernel layer): Load-linked start / stop: Real-time monitoring of server CPU utilization and memory usage. When CPU utilization > 80% or high-load tasks are executed, the Bluetooth module is automatically shut down to release hardware resources; the module restarts and restores the connection within 30 seconds after the task ends. Low-power monitoring: When the server is idle (no keyboard and mouse operation for more than 5 minutes), the Bluetooth module enters sleep or low-power mode (power consumption less than or equal to 10mW), only retaining monitoring for the "wake-up key combination (such as Ctrl+Alt+F12)". After the wake-up key combination is triggered, the Bluetooth keyboard and mouse resume full-function mode within 100ms. Furthermore, during the connection process, when Bluetooth communication is interrupted, encryption key verification fails, or other abnormalities occur: the Bluetooth control module automatically attempts to reconnect (reconnection strategy: retry once every 10 seconds in the first minute, retry once every 30 seconds from the second minute onwards, with a maximum of 10 retries). If reconnection fails, trigger a BMC system alarm and lock Bluetooth module operation permissions (allowing only the local console to unlock) to prevent unauthorized access.

[0081] Connection Scheduling Unit: Multi-Server Priority Allocation: When a set of Bluetooth keyboard and mouse switches connections to multiple servers, priority is dynamically allocated based on the server status.

[0082] Priority 1 (highest): Servers in "Operation and Maintenance Mode" with a load rate of less than 30%;

[0083] Priority 2: Servers in normal operating status and without critical tasks;

[0084] Priority 3: Servers that perform low-priority tasks (such as log backups).

[0085] Conflict resolution: when multiple servers request connection at the same time, prioritize the highest priority server for connection to avoid connection interruption caused by signal contention.

[0086] 3. Management layer: linkage with server BMC system: the start / stop state of the Bluetooth module, fault information (such as communication interruption, encryption key anomaly) is synchronized to the BMC health monitoring log, remote SSH, web console query is supported; when the module fails, automatically trigger three-level alarm (local LED indicator light flashing, BMC system pop-up window, operation and maintenance management platform email notification).

[0087] In this way, the application improves the Bluetooth connection stability from less than 90% in the traditional scheme to greater than or equal to 99.9% in the multi-server high-density deployment (distance less than 1 meter) scenario through the DRF technology and PCIe direct connection architecture, solving the industry pain point of data center Bluetooth signal being easily disturbed. Using SM4 national encryption algorithm to encrypt and store pairing information, combined with BMC system linkage and operation audit, meeting the requirements of the "Data Center Information Security Management Specification" for device connection and permission control, filling the security vulnerabilities of ordinary terminal Bluetooth management scheme in the server scenario. In addition, a set of Bluetooth keyboard and mouse supports up to 32 server switching control, reducing 80% of the USB (Universal Serial Bus, Universal Serial Bus) device procurement cost, while saving 2 hours of operation and maintenance time per server per year (based on 3 times of daily switching). Finally, through the deep cooperation of hardware-software management logic, it realizes: anti-interference Bluetooth connection suitable for high-density deployment in data centers; server-level pairing information encryption storage and permission control; intelligent Bluetooth module start-stop based on server load state and cross-server connection scheduling; compatible with data center hardware management specification state monitoring and alarm.
