[0048] In order to make the person skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in the following 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, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without any creative effort should belong to the scope of protection of the present application.

[0049] In order to better understand the present application, the embodiments of the present application will be explained in detail with reference to the accompanying drawings.

[0050] Embodiment One

[0051] Reference is made to Figure 1 , Figure 1 A structural schematic diagram of an opening box detection system for a communication device provided by an embodiment of the present application. It can be known from Figure 1 that the structure of the opening box detection system for a communication device in the embodiment mainly includes: a switch module, a clock module, a microprocessor with sleep function, a storage module and a power module.

[0052] The switch module is used for closing and shutting off operation according to the detected opening or closing action of the communication device, and triggering an interrupt to wake up the microprocessor; the clock module is used for recording the opening or closing time according to the closing and shutting off state of the switch module; the microprocessor is used for adjusting the working state according to whether there is external power input, reading the current time of the clock module and starting the storage module according to the triggering of the switch module, reporting the full-function state information to the BMC or CPU, and modifying the configuration information, the working state including: a sleep state and a full-function state, the full-function state information including: power-on information and authorized start information in the full-function state, and the configuration information including: a monitoring time point, monitoring content and a remote start key; the storage module is used for storing the opening event, the closing event, the opening time, the closing time and the full-function state information; and the power module is used for supplying power for the microprocessor, the storage module and the clock module in the state of no external power input.

[0053] When the switch module detects the opening or closing of the cover operation, the microprocessor is woken up by the interrupt triggered by the switch module, the microprocessor reads the current time of the clock module and writes it into the storage module, and the next time the power is turned on, the information of the storage module can be obtained through the operating system or the BMC, so that the opening time and the closing time in the power-on and power-off states can be recorded, and the real-time and detection efficiency of the opening detection of the communication device are greatly improved.

[0054] The communication device in the embodiment includes a computer, a server and the like. The microprocessor includes a working state adjusting unit, a control unit, a reporting unit and a configuration modifying unit. The working state adjusting unit is used for adjusting the working state of the microprocessor to the sleep state when there is no external power input, and adjusting the working state of the microprocessor to the full-function state when there is external power input. The setting of the working state adjusting unit can timely adjust the working state of the microprocessor, so as to adapt to different power supply states and ensure that the microprocessor can timely control each module to perform opening detection in different power supply states. When the microprocessor is in the full-function state, the state of the microprocessor can also be modified to the real-time reporting state after the communication device is powered on and started.

[0055] The control unit is used for reading the current time of the clock module and starting the storage module according to the triggering of the switch module, that is, when the switch module triggers the interrupt to wake up the microprocessor, the control unit reads the current time of the clock module and starts the storage module to store the current opening event and opening time; when the switch module triggers the interrupt to wake up the microprocessor, the control unit reads the current time of the clock module and starts the storage module to store the current closing event and closing time.

[0056] The reporting unit is used to report full-function status information to the BMC or CPU, as well as the unpacking status during the power outage period, after external power is input. Specifically, when the microprocessor is in full-function mode, it records the power-on time and authorized startup time. When the communication device powers on and starts up, it actively reports the unpacking status during the power outage period through the reporting unit, thus providing a basis for user security review.

[0057] The configuration modification unit is used to modify the configuration information of the BIOS and BMC.

[0058] Furthermore, the microprocessor in this embodiment also includes a clearing unit, used to clear the contents of the storage module after reporting the full-function status information and the unpacking status during the power outage period. The clearing unit facilitates the storage module's next recording and prevents storage module overflow, thus promoting full utilization of storage resources.

[0059] Furthermore, during the development and production stages of communication equipment, frequent unpacking and clearing of BIOS and BMC configurations are often required. In this case, the clearing unit can complete the clearing operation by short-circuiting the factory mode switch, thereby avoiding frequent information reporting, saving resources, and improving the efficiency of unpacking and testing.

[0060] The power module can use button batteries, which power the microprocessor, clock module, and storage module respectively.

[0061] This embodiment illustrates the principle of unpacking and testing communication equipment. (See attached diagram.) Figure 2 As shown. By Figure 2 As can be seen, the working principle of the unpacking detection system for communication equipment in this embodiment can be divided into two cases. The first case is when there is no external power input, and only a button battery is powered. In the case of button battery power, the microprocessor, RTC chip, and SRAM (Static Random-Access Memory) are powered. After detecting that there is no external power input, the microprocessor automatically enters a sleep state and writes the power-off time into the SRAM space. Opening and closing the box will trigger an interrupt to wake up the microprocessor. When the unpacking detection switch is detected to be closed, the signal edge changes, that is, from high level to low level, indicating that the box is opened. This event and time are written into the SRAM. After writing, it will enter sleep again, thereby reducing power consumption and ensuring battery life. When the unpacking detection switch is detected to be open, that is, from low level to high level, it is determined that the box is closed. This event and time are also recorded and written into the SRAM.

[0062] The second case is that there is an external power input, after the external power input, the button cell no longer provides power supply for the microprocessor and the RTC chip, the SRAM, and the microprocessor state is switched to a full function state. The microprocessor records the power-on information, the authorized start information, and can support functions such as modifying the BIOS and the BMC configuration information. After the system is started, the opening box state in the power-off period is actively reported for review by the security department. After the reporting is completed, the content of the SRAM is actively cleared for the next recording to prevent the SRAM from overflowing. After power-on, the microprocessing state can be modified to a real-time opening box state.

[0063] The microprocessor in the embodiment can select any one of the processors with a sleep function. The microprocessor is connected with the BMC or the CPU through a first bus, and the microprocessor is connected with the clock module through a second bus, wherein the first bus includes any one of an SMBUS bus, an SGPIO bus and a UART bus, and the second bus includes an I2C bus. The CPU and the BMC are active processors, and a user can actively access the microprocessor through an operating system and the BMC to modify and read data.

[0064] In the power-off state, a low-power microprocessor is used to complete data recording only in the micro-power level, so that data is not lost, and the data security is improved.

[0065] Further, in the embodiment, the microprocessor accesses a secure network, so that the microprocessor can be prevented from being modified by the BMC or the operating system, and the security of the microprocessor is improved, and the security of the opening box detection system for the communication device is improved.

[0066] The embodiment can also remotely authorize a start password, and then power-on after the start is allowed.

[0067] In the embodiment, the clock module can use an RTC clock chip, and the storage module can use an SRAM with ultra-low power consumption.

[0068] The clock module and the storage module can be arranged in the same chip in the embodiment. Specifically, the RTC clock chip and the SRAM are arranged in the same chip, and taking a DS3232SN chip as an example, the chip has a standard time counting function, and internally includes 236 bytes of SRAM. This structure design can effectively save the board space, reduce the circuit complexity, control the power consumption in uA, and is also beneficial to the protection of the battery life.

[0069] Embodiment two

[0070] In Figure 1 and Figure 2 the embodiment, the clock module and the storage module can be arranged in the same chip. Figure 3 , Figure 3A flowchart of a method for detecting opening of a communication device is provided in the embodiments of the present application. The method comprises the following steps. Figure 3 It can be seen that the method for detecting opening of a communication device comprises the following steps.

[0071] S1: determining whether there is external power input.

[0072] If there is external power input, step S2 is performed: the microprocessor enters a sleep state and detects opening of the communication device in the sleep state.

[0073] Specifically, step S2 comprises the following steps.

[0074] S21: after the microprocessor detects that there is no external power input, the microprocessor enters a sleep state and writes off power time into a storage module;

[0075] S22: when opening of the communication device is detected, the signal edge of the switch module is switched from high level to low level;

[0076] S23: the microprocessor writes the opening event and opening time into the storage module and enters the sleep state again;

[0077] S24: when closing of the communication device is detected, the signal edge of the switch module is switched from low level to high level;

[0078] S25: the microprocessor writes the closing time and closing time into the storage module.

[0079] If there is no external power input, step S3 is performed: the microprocessor enters a full-function state and detects opening of the communication device in the full-function state.

[0080] Specifically, step S3 comprises the following steps.

[0081] S31: after the microprocessor detects that there is external power input, the microprocessor enters a full-function state and writes full-function state information into a storage module.

[0082] The full-function state information comprises power-on information and authorized start information in the full-function state. At this time, the microprocessor can also support modification of BIOS and BMC configuration information, wherein the configuration information comprises monitoring time points, monitoring contents, and remote start keys. The configuration information is a monitoring strategy, and specifically, only power-on time can be monitored, only power-off time can be monitored, only opening operation can be monitored, real-time monitoring and reporting can be performed, or the function can be turned off and not monitored. A remote authorized start key can also be saved to control power-on and power-off operations.

[0083] S32: after the communication device is powered on and started, the full-function state information is reported to a BMC or a CPU.

[0084] S33: After reporting the full function state information and the opening box state in the power-off time period, the microprocessor clears the content of the storage module.

[0085] Further, in the embodiment, after reporting the full function state information and the opening box state in the power-off time period, the microprocessor clears the content of the storage module. The method can be selected to clear the content in the storage module by using a short-circuit factory mode switch. Since the development and production stage of the communication device needs to frequently open the box and clear the BIOS and BMC configuration, etc., the method can avoid frequent reporting of information, and is beneficial to further improve the resource utilization rate.

[0086] For the part described in detail in the embodiment, reference can be made to the embodiments shown in Figure 1 and Figure 2 The two embodiments can be referred to each other, and will not be described here again.

[0087] The above only is the specific embodiment of the present application, so that the person skilled in the art can understand or implement the present application. Various modifications of the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
