[0036] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] The core of this application is to provide a device, method and medium for preventing accidental unplugging of power cords, which are used to reduce the occurrence of accidental unplugging of power cords and improve the protection capabilities of systems and data.

[0038] 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. Figure 1 The present invention provides a device for preventing accidental unplugging of a power cord, such as Figure 1 As shown, the device includes a controller 1, a power sensor 2, and a clamp 3;

[0039] The clamp 3 is located at the power handle and is used to fix the power cord;

[0040] The clamping ring 3 is connected to the power sensor 2;

[0041] The controller 1 is used to send a command to control the collar 3 to the power sensor 2 ; the collar 3 is controlled to be locked or released via the power sensor 2 .

[0042] The current method of using the machine indicator light to locate the machine that needs to unplug the power cord is prone to accidental unplugging of the power cord in a dense server cluster. Therefore, in the embodiment of the present application, the locked or open state of the clamp is used to determine whether the power cord on the corresponding machine needs to be unplugged.

[0043] The clamp is located on the power handle and is used to secure the power cord. The clamp consists of an outer ring and an inner ring. The outer ring is usually made of an insulating material, such as plastic. Since the locking or release of the clamp is controlled by a power sensor, the inner ring is made of a metal ring. In practice, there is no restriction on the material of the metal ring. Preferably, in order to achieve more sensitive control of the clamp, a highly conductive metal can be selected as the inner ring of the clamp. The diameter of the clamp depends on the thickness of the power cord. In practice, the diameter of the clamp is usually slightly larger than the diameter of the power cord.

[0044] The clamp is connected to the power sensor, which is located on the power mainboard. There is a control module for the power sensor on the controller. The controller can send instructions to the power sensor, and then the magnetic attraction on the clamp is locked or opened through the power sensor.

[0045] When there are a large number of servers, all of them are controlled by a controller. Each server's power cord is equipped with a collar, and each collar is connected to a corresponding power sensor. When the controller needs to unplug the corresponding server, it usually uses the static IP address of each server to issue the command to the server that needs to be unplugged.

[0046] The device provided in this embodiment includes a controller, a clamp, and a power sensor. The clamp is located at the power handle and is used to secure the power cord. The clamp is connected to the power sensor. The controller is used to send a command to control the clamp to the power sensor. The power sensor controls the clamp to lock or release. Previous devices that used an indicator light on the entire machine to locate the machine requiring power cord unplugging were prone to accidental unplugging in dense server clusters. However, in the device provided in this embodiment, since the clamp is located at the power handle, it can more accurately determine the machine requiring power cord unplugging based on whether the clamp is locked or released, reducing the occurrence of accidental power cord unplugging and improving system and data protection.

[0047] As the demand for servers continues to increase, the number of servers in many computer rooms is getting larger and larger. Therefore, in order to facilitate the control of a large number of servers, the preferred implementation method is that the controller is a baseboard management controller (BMC).

[0048] The BMC controller supports the industry-standard Intelligent Platform Management Interface (IPMI) specification and is primarily used for remote management. Since a large number of servers need to be controlled, all servers can be controlled remotely through the BMC. When a BMC controller is used, the BMC controller has a remote control module for unlocking and locking the power sensor. This module sends a command to the power sensor to control the locking ring. The power sensor then performs the corresponding action according to the corresponding command, thereby locking or unlocking the locking ring.

[0049] The controller provided in this embodiment is a BMC controller, which enables remote control of each server and facilitates control of each server.

[0050] In practice, in order to achieve more sensitive control of the clamping ring, a preferred embodiment is that the metal ring in the clamping ring is made of silver or copper.

[0051] The material of the metal ring is not limited. If the metal ring has low conductivity, it may prevent the power sensor from locking or unlocking the clamp. Therefore, a highly conductive metal is used as the material for the metal ring in the clamp. The highly conductive metal is not limited. Since silver and copper have strong conductivity, the metal ring of the clamp used in this embodiment is made of silver or copper.

[0052] The metal ring in the clamp provided in this embodiment is made of silver or copper. Since silver or copper has good electrical conductivity, the clamp can be controlled more sensitively through the power sensor.

[0053] In order to be able to timely understand the plugging and unplugging status of the power cord and quickly find the server that needs to be plugged and unplugged, in implementation, as a preferred embodiment, the device for preventing accidental unplugging of the power cord also includes: a display screen;

[0054] The display is connected to the BMC controller and is used to display the plug-in and unplug-out status of the power cable.

[0055] The display screen is connected to the BMC controller to display the plug-in and unplug-out status of the power cord. There is no limitation on the way to display the plug-in and unplug-out status of the power cord on the display screen. For example, the plug-in and unplug-out status of each server can be displayed in the form of a list on the display screen. When the power cord is plugged in, it can be represented by 1; when the power cord is unplugged, it can be represented by 0. The plug-in and unplug-out status data of the power cord can be updated in real time on the display screen. When there is a server that is unplugging the power cord, the plug-in and unplug-out status data of the server will be marked on the display screen. According to the mark, the user can quickly find the server that needs to plug in and unplug the power cord.

[0056] The embodiment provides a display screen connected to the BMC controller to display the plug-in and unplug-out status of the power cord, so that the user can understand the plug-in and unplug-out status of the power cord through the display screen and quickly find the server that needs to plug-in and unplug the power cord.

[0057] Similarly, in order to facilitate users to find the server that needs to plug or unplug the power cord, the device for preventing accidental unplugging of the power cord also includes: an alarm device;

[0058] The alarm device is connected to the BMC controller and is used to give a prompt when the power sensor control collar is locked or released.

[0059] There are no restrictions on the specific alarm device and its corresponding alarm method, and it can be, for example, an indicator light, a buzzer, etc. When the power sensor control collar is locked or released, it indicates that the power cord has been unplugged or plugged in, and a prompt is displayed for the power cord that needs to be plugged in or out. The user can then find the corresponding server that needs to be plugged in or out according to the prompt information and plug or unplug the power cord of the corresponding server.

[0060] The embodiment provides a prompting device to notify the server that needs to plug or unplug the power cord, so that the user can quickly find the server that needs to plug or unplug the power cord.

[0061] On the basis of the above embodiments, the present application further provides a method for preventing the power cord from being unplugged by mistake, which is applied to the above-mentioned device for preventing the power cord from being unplugged by mistake. Figure 2This is a flow chart of a method for preventing accidental unplugging of a power cord provided by this application, such as Figure 2 As shown, the method includes:

[0062] S10: Sending a command to control the clamp ring to the power sensor;

[0063] S12: The power sensor controls the locking or release of the clamping ring.

[0064] The method for preventing the power cord from being unplugged accidentally provided in this embodiment has corresponding technical features to the device for preventing the power cord from being unplugged accidentally described above. The device for preventing the power cord from being unplugged accidentally has been described in detail above. Therefore, the method for preventing the power cord from being unplugged accidentally will not be described in detail here.

[0065] The method for preventing accidental power cord unplugging provided in this embodiment is applicable to the aforementioned device for preventing accidental power cord unplugging. The method includes sending a control collar instruction to a power sensor; and controlling the collar to lock or release via the power sensor. Previous methods that used indicator lights on the entire machine to locate the machine requiring power cord unplugging were prone to accidental power cord unplugging in dense server clusters. However, in the method provided in this embodiment, since the collar is located at the power handle, the locking or releasing of the collar can more accurately determine the machine requiring power cord unplugging, thereby reducing the occurrence of accidental power cord unplugging and improving system and data protection capabilities.

[0066] In practice, it is common that when the controller sends a command to control the collar to the power sensor, the power sensor is unable to control the collar. A preferred embodiment further includes:

[0067] If the clamping ring is not locked or released by the power sensor within a preset time after the command to control the clamping ring is issued, the process returns to the step of issuing the command to control the clamping ring to the power sensor.

[0068] There is no limit on the preset time. From the time the collar control command is issued, if the collar is not locked or released by the power sensor within the preset time, there is no need to wait and the collar control command is directly reissued to the power sensor, and the collar is subsequently locked or released by the power sensor.

[0069] The method provided in this embodiment can improve the control efficiency of the clamping ring by setting a preset time.

[0070] In the above embodiments, a method for preventing accidental unplugging of a power cord is described in detail. This application also provides corresponding embodiments of a device for preventing accidental unplugging of a power cord. It should be noted that this application describes the embodiments of the device from two perspectives: one is based on the functional module perspective, and the other is based on the hardware perspective.

However, in the device provided in this embodiment, since the collar is located at the power handle, it can more accurately determine the machine requiring power cord unplugging based on whether the collar is locked or released, reducing the likelihood of accidental unplugging and improving system and data protection.
