Description

Technical Field

[0001] The utility model belongs to the technical field of server chassis, and particularly relates to an alarm device and a server based on chassis intrusion detection. Background Art

[0002] In the daily operation and maintenance of server rooms, the security and stability of server chassis are of crucial importance. However, traditional server chassis often lack real-time monitoring and alarm mechanisms. When the chassis cover is accidentally opened or accessed without authorization, the computer room administrator may not be able to discover it in time, which may lead to serious problems such as damage to internal components of the server, data loss, or security leakage.

[0003] Moreover, in the existing design of server chassis, usually only the hardware performance and heat dissipation effect inside the chassis are concerned, while the state monitoring and alarm mechanism for the chassis cover are relatively few. Some advanced server chassis may be equipped with physical security measures such as door locks or password locks, but these measures can only prevent unauthorized access and cannot monitor the state of the chassis cover in real time.

[0004] In the prior art, there are also some server management systems that provide remote monitoring and alarm functions, but these functions usually can only monitor the internal operating state of the server, such as CPU temperature, memory usage, etc., and cannot directly monitor the state of the chassis cover. Therefore, when abnormal situations such as the chassis cover being opened or accessed without authorization occur, the computer room administrator may not be notified in time and thus cannot take corresponding measures in time.

[0041] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below with reference to the drawings in the specific embodiments. Obviously, the embodiments described below are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this patent.

[0042] As Figure 1 shown, the alarm device based on chassis intrusion detection provided by the present utility model is mainly applied to the abnormal opening of the server chassis. Among them, in order to detect the opening state of the chassis, a chassis cover is provided on the upper cover of the chassis. An induction switch is provided at the closing position between the chassis and the chassis cover. The induction switch can be a contact type induction switch or an optoelectronic switch, etc.

[0043] The induction switch is connected to a detection circuit, and the output terminals of the detection circuit are respectively connected to a timing circuit and an indicator alarm circuit; the output terminal of the timing circuit is connected to a sound alarm circuit. After receiving the intrusion signal transmitted from the output terminal of the detection circuit, the timing circuit periodically sends control information to the sound alarm circuit to make the sound alarm circuit emit intermittent alarms. The indicator alarm circuit can emit light alarms.

[0044] In this embodiment, as Figure 2 shown, the detection circuit includes: resistor R1, resistor R2, resistor R3, resistor R4, resistor R5, resistor R6, resistor R7, resistor R8, capacitor C1, capacitor C2, capacitor C3, capacitor C4, and operational amplifier U1; the first ends of resistor R1, capacitor C2, and resistor R3 are respectively connected to the power supply; the second interface of operational amplifier U1 is respectively connected to the second end of resistor R1, the first end of resistor R2, the first end of capacitor C1, and the first end of resistor R5; the third interface of operational amplifier U1, the second end of resistor R2, the second end of capacitor C1, the second end of resistor R4, the second end of capacitor C4, and the second end of capacitor C3 are respectively grounded; the first interface of operational amplifier U1 is respectively connected to the second end of capacitor C2, the second end of resistor R3, the first end of resistor R4, and the first end of resistor R6; the second end of resistor R5 is connected to the first end of induction switch SW1; the second end of induction switch SW1 is respectively connected to the first end of capacitor C3 and the second end of resistor R7; the fifth interface of operational amplifier U1, the first end of capacitor C4, and the first end of resistor R8 are respectively connected to the power supply; the fourth interface of operational amplifier U1 is respectively connected to the first end of resistor R7, the second end of resistor R6, the second end of resistor R8, and the output terminal of the detection circuit. Operational amplifier U1 uses an LM321MFX / NOPB operational amplifier.

[0045] As Figure 3 shown, for the timing circuit of this application, it specifically includes: resistor R11, resistor R12, capacitor C11, capacitor C12, capacitor C13, and timing chip U2. The first end of resistor R11 is connected to the input terminal of the timing circuit; the fourth interface of timing chip U2 is respectively connected to the second end of resistor R11, the first end of capacitor C11, and the first end of resistor R12; the second end of capacitor C11, the second end of resistor R12, the second end of capacitor C12, the second end of capacitor C13, and the first interface of timing chip U2 are respectively grounded; the eighth interface of timing chip U2 and the first end of capacitor C13 are respectively connected to the power supply; the fifth interface of timing chip U2 is connected to the first end of capacitor C12; the third interface of timing chip U2 is connected to the output terminal of the timing circuit. Timing chip U2 uses an NE555 timer.

[0046] As Figure 4 and Figure 5As shown in the figure, the indicator light alarm circuit of this embodiment includes: light-emitting diode D11, triode Q11, and resistor R13; the fourth interface of timing chip U2 is also connected to the base of triode Q11; the emitter of triode Q11 is grounded; the collector of triode Q11 is connected to the power supply through light-emitting diode D11 and resistor R13 in sequence.

[0047] The sound alarm circuit includes: resistor R21, resistor R22, capacitor C21, capacitor C22, diode D12, triode Q12, and buzzer U2; the emitter of triode Q12 is grounded, and the base of triode Q12 is connected to the input end of the sound alarm circuit; the collector of triode Q12 is respectively connected to the second end of buzzer U2 and the anode of diode D12; the first end of buzzer U2 is respectively connected to the second end of resistor R21, the second end of resistor R22, the first end of capacitor C21, and the first end of capacitor C22; the second ends of capacitor C21 and capacitor C22 are respectively grounded; the cathode of diode D12, the first end of resistor R21, and the first end of resistor R22 are respectively connected to the power supply.

[0048] It should be noted that an induction switch is provided at the closing part between the chassis and the chassis cover. When the chassis cover is opened, the detection circuit receives the intrusion signal sensed by the induction switch. At this time, the operational amplifier U1 of the detection circuit sends a control signal to the timing circuit and the indicator light alarm circuit. Here, due to the effect that the voltage across capacitor C2 does not change suddenly, the instantaneous voltage at the positive terminal of operational amplifier U1 is 5V at this time, which is higher than the voltage of 2.5V at the negative terminal. Therefore, the output terminal will output a high level.

[0049] The high level can trigger the conduction of triode Q11, and then the light-emitting diode D11 emits light. The light-emitting diode D11 can be set in the monitoring room or in a position with personnel monitoring to prompt the monitoring personnel.

[0050] The RST pin of the NE555 timer used by the timing chip U2 will be at a high level, enabling the NE555 timer to enter the normal working state, and by adjusting the resistance and capacitance of the peripheral capacitor of the NE555 timer, it outputs an oscillation waveform with a certain frequency, sending a control signal with an oscillation waveform to triode Q12, enabling triode Q12 to conduct, and then driving buzzer U2 to emit an alarm sound signal, which is conducive to sending a reminder message.

[0051] The alarm device based on chassis intrusion detection provided by this application can, through the induction switch, monitor in real time whether the chassis cover is closed. If the chassis cover is accidentally opened, the induction switch will immediately trigger the detection circuit, thereby ensuring the security of the internal components of the server. Especially in situations where unauthorized access or physical damage needs to be prevented, it can be used as a physical security measure.

[0052] The present application also provides a server, including: an alarm device based on chassis intrusion detection, a GPS positioning module, a BMC module, and a wireless communication module. The output end of the timing circuit is further connected to the BMC module, and the BMC module is connected to the wireless communication module. When the BMC module receives the intrusion signal sent by the timing circuit, the BMC module sends the intrusion information to the user's handheld terminal through the wireless communication module.

[0053] The BMC module is connected to the GPS positioning module and sends the location information to the user's handheld terminal through the wireless communication module. In this way, when an intrusion signal is detected, in addition to giving an audible and visual alarm, information can also be sent to the user's handheld terminal, such as a mobile phone or other terminals, to indicate the abnormal state. And the location information of the server can be sent through the GPS positioning module to facilitate the user to handle it in time.

[0054] The wireless communication module of the present application can adopt an RFID radio frequency module or a LoRa wireless communication module.

[0055] The GPS positioning module can adopt a G91 core chip, with a built-in GPS antenna, which automatically receives and synchronizes satellite signals for positioning, and sends information such as the current latitude and longitude geographical location and the standard Greenwich Mean Time to the BMC module through the serial port. It meets the monitoring requirements for the switch state of the server chassis. Furthermore, when the chassis cover is opened, the detection circuit will trigger the indicator alarm circuit, and through the flashing of the light or a specific color indication, an immediate fault or abnormality notification is provided to the operator or administrator. This intuitive alarm method can help quickly identify problems and take corresponding measures. The introduction of the timing circuit and the sound alarm circuit enables relevant personnel to be further reminded by sound when the chassis cover is opened. Furthermore, the possibility of human negligence or delayed response can be reduced, ensuring the security and stability of the server room. Through the combination of the detection circuit and the alarm circuit, the state of the chassis cover can be monitored in real time, providing convenience for the maintenance and monitoring of the server.
