In the prior art, a detection switch power supply for executing the unpacking detection and a board level management BMC are in the same group of electricity, the detection switch power supply and the board level management BMC can be monitored after the whole server is electrified, and once the power is off, the unpacking state of the server cannot be monitored, and unpacking during transportation or other malicious unpacking cannot be detected.
According to the application, the battery module is used for supplying power, and the delay register chip records the action signal and transmits the action signal to the BMC when the BMC is electrified, so that whether the server is opened or not can be monitored in the whole process.
The embodiment of the application discloses a server unpacking detection system, which is shown in fig. 1 and comprises the following components: the battery module comprises an action switch K, a delay register chip 1, a battery module 2 for supplying power to the action switch K and the delay register chip 1, and a BMC 3 connected with the delay register chip 1, wherein the action switch K, the delay register chip 1 and the battery module 2 are arranged on a shell of a case, and the BMC 3 is characterized in that:
when the case is opened, the action switch K acts and transmits an action signal to the delay register chip 1, and the delay register chip 1 keeps the action signal;
when BMC 3 is powered on, the delay register chip 1 sends an action signal to BMC 3.
It can be understood that when the BMC 3 is not powered on, the battery module 2 supplies power to the action switch K and the delay register chip 1, and at this time, if the chassis is opened, the action switch K acts to generate an action signal and the action signal is transmitted to the delay register chip 1 for storage; after BMC 3 is powered on, the delay register chip 1 uploads the action signal received when BMC 3 is not powered on to BMC 3 so as to remind staff: the chassis is opened when the AC is powered down.
It can be understood that the action switch K is arranged on the shell of the case, the on-off state of the action switch K changes when the case is opened, and according to the relative position relation between the action switch K and the shell of the case, the action switch K can be set to be opened when the case is opened and closed when the case is closed, and the action switch K can also be set to be closed when the case is opened and opened when the case is closed; the action switch K is connected with the battery module 2 to form a power supply loop, the power supply loop is turned on when the action switch K is turned on, and is turned off when the action switch K is turned off, so that the potential change of the action switch K when the case is opened is used as an action signal to be sent to the delay register chip.
It will be appreciated that fig. 1 is taken as an example, wherein the action switch K is specifically used to:
when the case is opened, the action switch K is turned off, and an action signal is transmitted to the delay register chip 1.
Further, in this embodiment, when setting a potential change at the time of the switching operation K as an operation signal, the specific embodiment includes:
the first end of the operation switch K is grounded, and the second end is connected to the battery module 2 through the first resistor R1.
At this time, the rising edge level of the second end of the operation switch K is used as an operation signal, the operation switch K is closed when the chassis is closed, the level of the second end is the same as the ground end, the chassis is opened, the operation switch K is opened, the level of the second end is the same as the output voltage of the battery module 2, that is, the level of the second end of the operation switch K rises when the chassis is opened, and the rising edge level is used as an operation signal.
Meanwhile, when the battery module 2 is connected with the delay register chip 1, the battery module is usually connected to the corresponding pin of the delay register chip 1 through the second resistor R2 as a buffer.
Further, the action switch K is usually connected to the battery module 2 through a connector and a cable, and corresponding protection grounding wires are provided at both ends of the connector.
Further, the BMC 3 is further configured to send a reset signal to the delay register chip 1, so as to reset the delay register chip 1. It can be understood that after the BMC 3 receives the action signal when not powered on last time, the delay register chip 1 does not need to store the action signal any more, and the existence of the action signal can prevent the delay register chip 1 from monitoring the subsequent unpacking condition, so that the delay register chip 1 is reset through the BMC 3, and the full-period availability of the server unpacking detection system is ensured.
In this embodiment, the delay register chip 1 may be specifically selected as a D flip-flop, and the battery module 2 specifically includes an RTC (real_time Clock) battery. In addition, the delay registering chip 1 and the battery module 2 may be implemented by selecting other elements, which are not limited herein.

According to the application, the battery module is used for supplying power, and the delay register chip records the action signal and transmits the action signal to the BMC when the BMC is electrified, so that whether the server is opened or not can be monitored in the whole process.

Furthermore, the server out-of-box detection system further includes a filter circuit 4 connected between the delay register chip 1 and the BMC 3, and may be implemented by a schmitt trigger to ensure that the signal has no jitter and the rising edge of the signal is accurate, and the power supply of the filter circuit 4 is usually completed by the system power supply 3v3_syby.
Further, in order to save the current of the battery module 2, when the BMC 3 is powered on, the system power supply 3v3_syby may supply power to the action switch K and the delay register chip 1. The specific circuit is shown in fig. 2, the output end of the battery module 2 and the system power supply 3v3_syby are connected with a diode, and then connected with the action switch K and the power supply end of the delay register chip 1, and the arrangement of the diode ensures that no backflow occurs between the battery module 2 and the system power supply 3v3_syby.
