In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an uncapping alarm system provided in the present invention, the uncapping alarm system includes:
the mechanical switch 1 is arranged on the case cover and is used for communicating a first contact and a second contact of the mechanical switch when the case cover is closed;

the processor 3 is connected with the other one of the first contact and the second contact at the detection end and is used for controlling the alarm device 4 to give an alarm when the detection end cannot detect the high level;
and an alarm device 4 connected to the processor 3.
Specifically, in view of the technical problems in the background art, in the embodiment of the present invention, firstly, a mechanical opening is set on a chassis cover, and the chassis cover is intended to implement a cover opening detection through a change in a connection state of a contact, and further, in view of the fact that the cover opening detection cannot be normally performed due to a problem occurring in a detection line, two conditions, i.e., a contact state and a line normal state, may be used as necessary conditions for determining that the chassis cover is not opened in the embodiment of the present invention, and an alarm may be issued only when one of the conditions is changed, e.g., the contact state is changed to an open state and/or the detection line has a problem, and it is considered that the chassis cover is opened and/or the detection line has a problem at this time, and the case cover can be detected while preventing the cover opening detection from being impossible to perform the cover opening detection due to, The price of the level pull-up circuit 2, the processor 3 and the alarm device 4 is low, and the cover opening alarm system is low in cost.
The mechanical switch 1 may be of various types as long as the conditions required to be met by the above-mentioned mechanical switch 1 are met, and the embodiment of the present invention is not limited herein.
Specifically, the mechanical switch 1 may be connected to the chassis cover by using a connection component, so that the opening and closing of the chassis cover drives the mechanical switch 1 to move, and thus the first contact and the second contact of the mechanical switch 1 are communicated only when the chassis cover is closed.
Specifically, when detecting "non-high level", the processor 3 can only determine that the chassis cover may be opened currently, and may also be that a detection line has a problem, and the processor 3 can clearly distinguish two states of "high level" and "non-high level", so in the embodiment of the present invention, it may be determined that the chassis cover is not opened when detecting high level, and directly alarm when detecting "non-high level", where "non-high level" includes a high impedance state in which a low level and a detection line are suspended, in the embodiment of the present invention, the processor 3 may perform high level detection through a "level triggered" detection module, for example, it may be determined that high level is when the detection level voltage reaches 3V, and when a problem occurs in the detection line, the detection end is suspended and presents a high impedance state, because the high impedance state presents a half high level, therefore, the voltage value of the voltage does not reach the preset 3V, and therefore, the voltage cannot be determined as high level, that is, determined as "non-high level", so as to trigger the alarm device 4 to alarm.
The high-level voltage value provided by the level pull-up circuit 2 may be set autonomously, which is not limited herein.
Specifically, the processor 3 may be of various types, for example, BMC (Baseboard Management Controller), and the embodiment of the present invention is not limited herein.
The level pull-up circuit 2 may be of various types, for example, the level pull-up circuit 2 may be composed of a reference power supply and a pull-up resistor, and the embodiment of the present invention is not limited herein.
The invention provides a cover opening alarm system, wherein a mechanical switch is communicated with a first contact and a second contact only when a machine case cover is closed, a level pull-up circuit is enabled to pull up the level of a detection end of a processor, once a server case cover is opened, the processor can control an alarm device to alarm because the detection end cannot detect the high level, and as a lead connected between the mechanical switch, the level pull-up circuit and the processor is one of necessary conditions for ensuring that the high level is transmitted to the detection end of the processor, when the lead goes wrong, the processor can control the alarm device to alarm, so that the alarm device can be conveniently overhauled in time to ensure the normal operation of the cover opening alarm system.
