Embodiment 1

[0023] Such as Figure 1 to Figure 5 As shown, a computer accessory with a detection function for preventing strong electromagnetic interference includes a single-chip microcomputer 1, an infrared pyroelectric sensor 2, a power supply module 3, a lighting module 4, and an illumination detection module 5; wherein, the digital power supply terminal of the power supply module 3 It is connected with the power input terminal of the single-chip microcomputer 1, the infrared pyroelectric control terminal of the single-chip microcomputer 1 is connected with the output terminal of the infrared pyroelectric sensor 2, the lighting control terminal of the single-chip microcomputer 1 is connected with the control terminal of the lighting module 4; the power supply module 3 is a single-chip microcomputer Power supply, the infrared pyroelectric sensor 2 receives the infrared rays radiated by the human body and converts it into an electrical signal and sends it to the single-chip microcomputer...

Embodiment 2

[0028] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the operational amplifier A1, operational amplifier A2, operational amplifier A3, and operational amplifier A4 are all LM324 chips.

Embodiment 3

[0030] Such as Figure 6 to Figure 7 As shown, this embodiment is a preferred solution. The difference between this embodiment and Embodiment 1 to Embodiment 2 is that the front end of the computer housing 6 is provided with a mounting part a7, and the rear end is provided with a mounting part b8. The infrared pyroelectric The sensor 2 and the light intensity detection module 5 are arranged at the installation part a7, the lighting module 4 is arranged at the installation part b7, and both the installation part a7 and the installation part b8 communicate with the outside world.

[0031] Among them, the infrared pyroelectric sensor 2 and the illuminance detection module 5 are installed at the front end of the computer for easy monitoring, and the lighting module 4 is installed at the back end of the computer, one is to prevent the LED light from directly shining on the eyes, and the other is to further create a good visual atmosphere and protect the eyes.

Abstract

The invention discloses a computer accessory with a detection function for preventing strong electromagnetic interference, which solves the problem of poor visual effect created only by the illumination emitted from a computer screen under the condition of no light at night, and having certain harm to eyes. With the feeling to open the computer, a user is easy to bump against the foot of the desk,computer hardware or other sharp places, causing harm. The computer accessory with a detection function for preventing strong electromagnetic interference of the invention comprises a single chip microcomputer, an infrared pyroelectric sensor, a power supply module, a lighting module and an illumination detection module. The invention has the advantages of lighting the lamp when a person is close, turning off the lamp when the person leaves, saving energy, creating a good visual atmosphere, protecting eyes and the like.

Description

technical field [0001] The invention relates to a computer accessory, in particular to a computer accessory with a detection function for preventing strong electromagnetic interference. Background technique [0002] Many computer rooms contain densely packed computers. On sunny days, there is enough light to meet the needs of work. However, on rainy days or in the evening, the light is not enough. When the staff checks, it is easy to touch other places and cause misuse. There are many electronic devices in the computer room, and the lights are easily damaged. electromagnetic interference. [0003] In view of the above problems, the only intuitive idea of ​​those skilled in the art is to install electric lights in the computer room, but there are many computers in the computer room, some places cannot be illuminated by electric lights, and the light is dim, which is not conducive to the daily inspection and maintenance of operators. Contents of the invention [0004] The t...
