Detailed Description

To make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, an aspect of the present invention provides a cover opening detection device 3, which includes a photosensitive module 32 and a determination module 31;

the photosensitive module 32 is installed in the chassis 1, and is configured to sense light outside the chassis 1 and output a corresponding photosensitive signal when the chassis 1 is in an open state;

the judging module 31 is connected to the photosensitive module 32, and is configured to receive a photosensitive signal output by the photosensitive module 32 to determine that the chassis 1 is in an open state;

the photosensitive module 32 is disposed on the circuit board 2 in the case 1 and is in signal connection with the determining module 31.

In this embodiment, the case 1 may be a server case, a computer host case, an electrical apparatus case, and the like, and specifically includes a cover plate 12 and a case 11 having a cavity, the photosensitive module 32 is specifically installed on a surface of the circuit board 2 in the case 11, which faces an opening of the case 11, the photosensitive module 32 may be an optical sensor, a photo resistor, and the like, and the circuit board 2 may be a video card, a motherboard, a sound card, and the like. As shown in fig. 1, when the chassis 1 is in the open-lid state, external light irradiates the photosensitive module 32, and the photosensitive module 32 generates a photosensitive signal after receiving the light, where the photosensitive signal may be a pulse voltage or a variable voltage/current.

The determination module 31 may be installed on the circuit board 2 in the box 11, or may be installed at another position of the chassis 1, and is generally in signal connection with the photosensitive module 32 through a data line, and the determination module 31 may specifically be a BMC (Baseboard management Controller) module in the chassis 1, and is connected to the photosensitive module 32 through an ADC interface, or may be a light/speaker. When the light sensing module 32 sends a light sensing signal, the determining module 31 receives the light sensing signal and sends a signal indicating that the case 1 is in the open state, where the signal may be light emitting/sound emitting or may be a computer instruction.

On the contrary, when the chassis 1 is in the closed state, since the light sensing module 32 cannot sense the external illumination, and further cannot generate a corresponding light sensing signal, the determining module 31 cannot emit light/sound or generate a computer instruction, and at this time, it can be determined that the current chassis 1 is in the closed state.

From this, according to sensitization module 32 to the external illumination perception machine case 1 current state of quick-witted case 1 be state of uncapping/closed state, set up a cable module of taking telescopic switch in quick-witted case 1 for current scheme, this scheme has saved the complex construction based on telescopic switch to can be with perception module direct mount on circuit board 2, simple to operate and simple structure.

In this embodiment, the power source 321 may be a power source 321 provided in the enclosure 1, or may be an independent power source 321 such as a battery. The logic used is: when the chassis 1 is in a closed state, and the photosensitive module 32 is in a stable operation, a voltage or current value generated by a connection point a (i.e., a second end of the photosensitive element 322) between the photosensitive element 322 and the resistor 323 is a, the voltage or current value a at this time is relatively stable, when the chassis 1 is in an open state, the photosensitive element 322 is illuminated by light outside the chassis 1 and a resistance value change occurs itself, the voltage or current value a at this time is changed into a voltage or current value b, and the voltage or current value b is a photosensitive signal, where the change mode may be an increase or a decrease. After receiving the changed voltage or current signal, the determining module 31 determines that the chassis 1 is currently in the open state.

In one embodiment, the photosensitive element 322 is a photo resistor or a photo diode.

In this embodiment, the photo-resistor or the photo-diode has different resistance values under different illumination environments, taking a general visible light photo-resistor as an example, the resistance value can be changed from 100k to 1k within the range of 1-100 lux brightness, the voltage or current difference generated is large, and the detection is easy.

Another aspect of the present invention provides a chassis, where the chassis 1 at least includes the above-mentioned open cover detection device 3.

In this embodiment, the case 1 may be a server case, a computer host case, an electrical equipment case, or the like. The uncovering detection device 3 is specifically installed on one side, facing to the cover plate 12 of the case 1, of the circuit board 2 in the case 1, when the cover plate 12 of the case 1 is opened, the uncovering detection device 3 is illuminated by the outside and makes corresponding instructions to determine that the current case 1 is in an uncovering state, otherwise when the cover plate 12 of the case 1 is not opened, the uncovering detection device 3 is not illuminated by the outside, and the uncovering detection device 3 does not send instructions to determine that the current case 1 is in a closing state.
