Fig. 1 is a block diagram illustrating an example of a server chassis lid opening detection apparatus according to an embodiment of the present application.

As shown in fig. 1, the server casing lid opening detection apparatus 100 includes a power interface 110 of the server, a backup battery unit 120, a lid opening detection controller 130, and a lid opening trigger switch 140. Specifically, the lid opening detection controller 130 is connected to the power interface 110 of the server and the battery backup unit 120, the first switch state and the second switch state of the lid opening trigger switch 140 correspond to the closing state and the lid opening state of the server lid, respectively, and the lid opening trigger switch 140 in the second switch state is used for triggering the battery backup unit 120 to supply power to the lid opening detection controller 130. Here, the cover opening detection controller 130 may detect whether the server chassis is in the cover opening state according to the state of the cover opening trigger switch 130.

Specifically, the uncovering detection controller 130 may perform function operations such as detection, recording and alarm on the uncovering state of the server cover, and the carrier form of the uncovering detection controller 130 may be any controller or processor on the server motherboard, for example, a CPLD (Complex Programmable Logic Device) may be used. The power interface 110 of the server may be a power plug, for example, for connecting ac power (e.g., mains ac power) to a motherboard of the server. The backup battery unit 120 may be independently powered to implement a backup power function when the power interface of the server is powered off, and it should be understood that the backup battery unit 120 may be any suitable type of power source, and should not be limited thereto. The first switch state and the second switch state of the lid opening trigger switch 140 correspond to the opening state of the server lid, respectively, for example, the first switch state represents the switch closing state and the second switch state represents the switch opening state, or the first switch state represents the switch opening state and the second switch state represents the switch closing state. For example, the cover-opening trigger switch may be disposed on the server chassis, and when the server chassis is opened, the cover-opening trigger switch is triggered to switch from the first switch state to the second switch state. In addition, the open cover trigger switch 140 in the second switching state is used to trigger the battery backup unit 120 to supply power to the open cover detection controller 130.

In one example of the embodiment of the present application, the battery backup unit 120 may monitor the switching state of the lid opening trigger switch 140, and the battery backup unit 120 enters the standby state without supplying power when the lid opening trigger switch 140 is in the first switching state, and the battery backup unit 120 enters the operating state when the lid opening trigger switch 140 is in the second switching state, thereby supplying power to the lid opening detection controller 130.

In another example of the embodiment of the present application, the cap-open trigger switch 140, the cap-open detection controller 130, and the battery backup unit 120 may be connected in series. Specifically, the open lid trigger switch 140, the open lid detection controller 130 and the battery backup unit 120 in the first switching state constitute an open circuit therebetween, and the open lid trigger switch 140, the open lid detection controller 130 and the battery backup unit 120 in the second switching state constitute a closed circuit therebetween. Therefore, when the server case is opened, the uncovering trigger switch can be switched to the second switch state to trigger the standby battery unit to supply power to the uncovering detection controller on the access, and the uncovering detection controller can still work normally under the condition that the interface power supply is powered off.

Fig. 2 is a flowchart illustrating an example of a server chassis decapping detection method according to an embodiment of the present application, which may be performed by an decapping detection controller.

As shown in fig. 2, in step 210, the switch state of the uncap trigger switch is acquired. For example, after the door opening detection controller is powered on, the door opening detection controller may detect whether the door opening trigger switch is in the first switching state or the second switching state.

In step 220, whether the server chassis is in the uncapped state is correspondingly determined according to the acquired switch state of the uncapped trigger switch. Specifically, the uncovering detection controller may determine that the server chassis is in the closed state when detecting that the uncovering trigger switch is in the first switching state, and may determine that the server chassis is in the open state when detecting that the uncovering trigger switch is in the second switching state, so that whether the server chassis is in the uncovering state may be determined by detecting the switching state of the uncovering trigger switch.

In some embodiments, when the lid opening detection controller detects that the lid opening trigger switch is switched from the second switch state to the first switch state, and the server lid is closed, the lid opening detection controller can control the standby battery unit to be powered off and reset the system.

Fig. 3 is a flowchart illustrating an example of a server chassis decapping detection method when the decapping trigger switch is in the second switch state according to an embodiment of the present application.

In step 310, the state of the power interface of the server is detected while the lid-open trigger switch is in the second switch state.

If the detection result in step 310 indicates that the power interface of the server is in a powered state, it jumps to step 321. If the detection result in step 310 indicates that the power interface of the server is in a power-off state, it jumps to step 323.

In step 321, the battery backup unit is powered down. For example, the backup battery may be in an off state or a standby state without supplying power to the open-cover detection controller.

As described above, when the lid opening trigger switch is in the second switch state, the battery backup unit is triggered to supply power to the lid opening detection controller. In addition, when the server power interface is in a power-on state, the cover opening detection controller can also supply power through the server power interface. At this time, there may be two power supply lines for the decap detection controller.

In this application embodiment, when uncap trigger switch is in the second on-off state, uncap and detect the state that controller can detect the power interface of server to when the power interface of server is in electrified state, uncap and detect the controller and can make the outage of reserve battery unit, thereby practice thrift the electric quantity of reserve battery unit, in order to ensure sufficient duration.

In step 323, the battery backup unit is de-energized after a set period of time has been reached by the battery backup unit. Here, the set time period may be set according to an application scenario to satisfy a processing time required for operations such as decap detection, information recording, user prompt, and the like.

In the embodiment of the application, the standby battery unit is powered off after the standby battery unit continuously supplies power for a set time period, so that the standby battery unit does not need to be powered off all the time, and the cruising ability of the standby battery unit can be improved while the case cover opening detection function of the server is realized.

Fig. 4 is a flowchart illustrating an example of a server chassis decapping detection method according to an embodiment of the present application.

As shown in fig. 4, in step 410, the on-off state of the lid opening trigger switch is acquired.

In step 420, whether the server chassis is in the uncapped state is correspondingly determined according to the acquired switch state of the uncapped trigger switch.

If the decap trigger switch in step 420 is in the first switch state, it jumps to step 431. If the uncap trigger switch in step 420 is in the second switch state, it jumps to step 433.

In step 431, it is determined that the server cover is in a normally closed state.

In step 433, it is determined that the server lid is in an open state and a lid open detection event is generated.

Next, in step 440, various decap management operations are performed based on the decap detection event.

In some examples of the embodiment of the present application, based on the generated decapping detection event, an decapping prompt operation is performed, for example, a corresponding decapping message may be displayed on a display screen connected to the server, or a prompt message may be sent to a preset mobile terminal through a wireless transmission device, and an operation and maintenance person may be notified in time to perform security management on the server.

In some examples of embodiments of the present application, the battery backup unit is powered down based on an open cover detection event when a power interface of the server is in a dead state. In combination with the application scenario, when the uncapping detection event is generated, the operation processes such as detection and recording for the uncapping operation at this time are already completed, and at this time, the standby battery unit is powered off, so that the power consumption of the standby battery unit can be saved.

In some examples of the embodiment of the present application, the uncap detection controller may further update the uncap detection history of the server based on the generated uncap detection event. Illustratively, when the uncapping detection event is generated, the uncapping detection event can be added into the uncapping detection history record of the server, so that operation and maintenance personnel can conveniently check the uncapping times and related information of the server, and the hardware security of the server can be comprehensively evaluated.

FIG. 5 illustrates a schematic diagram of an example of power interface (or motherboard power) power supply lines operating while BBU (Backup battery unit) power supply lines are not operating, according to an embodiment of the application.

As shown in fig. 5, in order to enable the server to realize the function of chassis cover opening detection even in the case of power failure, a BBU power supply line is designed. When the server case cover is closed and the power interface is connected with the alternating current, the CPLD of the mainboard detects that the alternating current input of the power supply is a normal High level (High), and the cover opening switch signal is the High level (High). In this state, the cover of the chassis is opened, and at this time, the CPLD (which may integrate the function of the cover opening detection controller) may detect that the cover opening switch signal is Low, and then the CPLD reads the count of the EEPROM (electrically erasable programmable read only memory) and performs cumulative addition of 1, and then stores the count in the EEPROM, thereby completing the cover opening detection record. At this time, the BBU power supply circuit can be in a standby state (Low), and the BBU is powered off.

FIG. 6 shows a schematic diagram of an example of a motherboard power supply not operating properly and a BBU power supply line operating, according to an embodiment of the present application.

As shown in fig. 6, when the server chassis cover is closed and the power interface does not receive ac power, the whole motherboard is powered off, the CPLD does not operate, the cover opening switch signal cannot be detected to be High, and cover opening detection cannot be realized. In this state, when the chassis cover is opened, the BBU circuit detects the Low level at the power interface, and the cover opening switch signal is Low level (i.e. the server chassis cover is opened), the BBU starts the power output to supply power to the CPLD and the EEPROM circuit, then the CPLD detects that the cover opening switch signal is Low, reads the count of the EEPROM and adds 1 in an accumulation manner, and then stores the count in the EEPROM to complete the cover opening detection record. And then, the CPLD can send a counting completion signal to the BBU, and the power supply output is closed after the BBU receives the counting completion signal, so that the single-switch detection function is realized. When the machine case cover is closed again, after the CPLD receives the cover opening switch signal as High, the situation is reset to wait for the next cover opening detection operation.

In the embodiment of the application, the uncovering detection function of the chassis of the server (for example, a platform server) is realized through the BBU power supply line, the BBU power supply line is controlled through the uncovering switch in the system power-off state, the BBU independently supplies power to the mainboard CPLD after uncovering for a set time period (for example, 3 seconds), the mainboard CPLD can update and store the uncovering count, and the uncovering detection function of the chassis under the power-off condition of the mainboard power supply is realized.

For the server chassis lid opening detection device 100, it should be noted that, because the contents of information interaction, execution processes and the like between the devices/units are based on the same concept as that of the method embodiment of the present application, specific functions and technical effects thereof may be specifically referred to a part of the method embodiment, and details are not described here.
